fixed prop cutoff issue for pr/issue filtering

…ti-CALL gaps #1: scopedCallerLookup(null) now uses owningModuleId(lineNum) instead of parentId, fixing PERFORM/MOVE/GOTO before first paragraph in nested programs. #2+#3: CALL and CANCEL extraction now uses matchAll (global flag) to capture multiple occurrences on the same line. Dynamic CALL/CANCEL checked independently instead of in else branch. #4: SORT/MERGE ACCESSES edge IDs now use owningModuleId(sort.line) instead of parentId for nested program correctness. #5: preprocessCobolSource free-format detection now uses first 10 lines (consistent with extractCobolSymbolsWithRegex threshold). #6: EXCLUDED_PARA_NAMES expanded with DISPLAY, ACCEPT, WRITE, READ, REWRITE, DELETE, OPEN, CLOSE, RETURN, RELEASE, SORT, MERGE to prevent false-positive paragraph detection on isolated verbs. Also removed unused GraphNode import from cobol-processor.ts. Tests: 145 passing | TypeScript clean

…g anchors #1+#2: Removed incorrect hasQuotedCall/hasQuotedCancel deduplication guards. RE_CALL_DYNAMIC and RE_CANCEL_DYNAMIC require [A-Z] after CALL/CANCEL, so they CANNOT match quoted targets — the guards were both unnecessary and actively harmful, suppressing dynamic CALL/CANCEL in ON EXCEPTION patterns. #3+#5: Changed RE_CALL_DYNAMIC and RE_CANCEL_DYNAMIC trailing anchor from (?:\s|\.) to (?=\s|\.|$) (lookahead). The consuming anchor failed when the identifier was the last token on a physical line. Tests: 168 passing | TypeScript clean

…guard #1: callAccum continuation lines now check for COBOL statement verb starts (GO TO, PERFORM, MOVE, etc.) and paragraph/section headers. If detected, the CALL is flushed as-is and the line processed normally — prevents false paragraph detection and currentParagraph corruption from lines like "WS-ADDR." being treated as paragraphs. #4: callAccum pre-check now guarded by currentDivision === 'procedure' to prevent unnecessary activations in DATA DIVISION. #5: Fixed-format paragraph detection now rejects lines with >7 leading spaces (Area B indentation) as paragraph candidates. Paragraph names in fixed-format must start in Area A (col 8-11, max 7 spaces). Free-format mode is unaffected. Tests: 168 passing | TypeScript clean

* feat: add COBOL language support with regex extraction pipeline Standalone COBOL processor following the markdown-processor.ts pattern: - No LanguageProvider modification — COBOL uses regex, not tree-sitter - No SupportedLanguages enum change — standalone processor pattern New files: - cobol-processor.ts — orchestrator (processCobol, isCobolFile, isJclFile) - cobol/cobol-preprocessor.ts — regex state machine extraction (~888 LOC) - cobol/cobol-copy-expander.ts — COPY statement expansion with circular detection - cobol/jcl-parser.ts — JCL job/step/DD extraction - cobol/jcl-processor.ts — JCL graph node creation Extraction produces: - Module nodes (PROGRAM-ID) - Function nodes (paragraphs) - Namespace nodes (sections) - Property nodes (data items) - CALLS edges (PERFORM intra-file, CALL cross-program) - IMPORTS edges (COPY statements) - CONTAINS edges (section → paragraph hierarchy) Pipeline integration: single processCobol() call in Phase 2.6 54 new tests (33 COBOL + 21 JCL), all 3889 tests pass. * docs: document custom processor pattern in pipeline.ts Add comment block at the custom processor integration point documenting the pattern for future non-tree-sitter language additions. * feat(cobol): enrich graph with EXEC SQL/CICS, ENTRY points, MOVE data flow, PERFORM THRU Maps the remaining 60% of CobolRegexResults to the graph: - EXEC SQL blocks → CodeElement nodes + ACCESSES edges to DB tables - EXEC CICS LINK/XCTL → CodeElement nodes + cross-program CALLS edges - ENTRY points → Constructor nodes (registered for cross-program resolution) - MOVE statements → ACCESSES edges (read/write data flow tracking) - PERFORM THRU → expanded CALLS edges for range targets - File declarations → Record nodes with assignment metadata - Cross-program CALL 2nd pass: resolves unresolved targets after all programs processed * test(cobol): add 26 integration tests with exact assertions + fix CICS resolution bug Integration tests (test/integration/resolvers/cobol.test.ts): - 26 tests covering full COBOL system extraction - ALL assertions use exact toBe(N) — zero fuzzy assertions - Fixtures: CUSTUPDT.cbl, AUDITLOG.cbl, CUSTDAT.cpy, RPTGEN.cbl, RUNJOBS.jcl Bug fix (cobol-processor.ts): - CICS LINK/XCTL cross-program resolution was broken — edges were created with "resolved" reason but pointing to <unresolved> targets - Fix: use cics-link-unresolved / cics-xctl-unresolved suffix pattern matching the existing cobol-call-unresolved pattern - Second-pass resolver now patches both CALL and CICS unresolved edges All 3915 tests pass, 0 failures. * test(cobol): exhaustive 57-test suite with strict exact assertions Complete rewrite of COBOL integration tests using ground-truth approach: dump the full graph, then assert EVERY node and EVERY edge. 57 tests across 9 sections: - Node completeness: Module(3), Function(13), Namespace(2), Property(21), Record(1), CodeElement(8), Constructor(1) — exact sorted arrays - Edge completeness: 22 tests covering every type+reason combination with exact source→target pairs - Cross-program resolution: 6 tests verifying CALL, CICS LINK/XCTL, JCL - COPY expansion: copybook data items in RPTGEN - Section hierarchy: exact paragraph membership per section - Data item ownership: exact per-module breakdown - MOVE data flow: exact read/write pairs - JCL integration: job/step/dataset containment - Grand totals: CALLS(22), CONTAINS(48), IMPORTS(1), ACCESSES(7) Fixture enhancements: - CUSTUPDT.cbl: added INIT-SECTION + PROCESSING-SECTION, PERFORM THRU - AUDITLOG.cbl: added ENTRY "AUDITLOG-BATCH" - RPTGEN.cbl: added EXEC CICS XCTL Zero fuzzy assertions — every expect uses toBe(N) or toEqual([...sorted]). * fix(cobol): add removeRelationship API + single-quote CALL/COPY/ENTRY, PERFORM keyword skip Phase 0A: Add removeRelationship(id) to KnowledgeGraph interface and implementation (trivial Map.delete wrapper). Required for orphan edge cleanup in next commit. Phase 1A (from PR #500 review, modified): - RE_CALL and RE_COPY_QUOTED now match both "double" and 'single' quotes - parseSingleCopyStatement in copy-expander updated for single quotes - PERFORM_KEYWORD_SKIP set prevents UNTIL/VARYING/WITH/TEST/FOREVER from being stored as false-positive perform targets - Sequence number stripping uses /[^0-9 ]/ (preserves numeric seq numbers unlike PR #500's /\S/ which stripped them) - Normalized || to ?? for regex group extraction in copy-expander 5 new graph unit tests, all 57 COBOL integration tests pass. * fix(cobol): RE_ENTRY single-quote + remove orphan unresolved CALLS edges Phase 1B: RE_ENTRY regex now supports both "double" and 'single' quoted ENTRY targets. Uses named intermediates (entryName, usingClause) with ?? operator. USING capture group shifted from [2] to [3]. Phase 1C: Second-pass resolution now collects resolved orphan edge IDs during iteration and removes them after the loop completes, using the new graph.removeRelationship() API. Graph no longer contains phantom <unresolved>: edges alongside their resolved replacements. CALLS count drops from 22 to 18 (4 orphan edges removed). * fix(cobol): Property ID collisions + O(1) Map lookup for MOVE edges Phase 1D+3C (atomic): Property node IDs now use composite key filePath:section:level:name instead of filePath:name. This prevents duplicate data item names in different sections (e.g., STATUS in both WORKING-STORAGE and LINKAGE) from silently colliding. New generatePropertyId() helper ensures both node creation and MOVE edge lookup use the identical key formula. buildDataItemMap() replaces the O(n) findDataItemNode linear scan with O(1) Map lookup, built once per file before MOVE processing. * feat(cobol): MOVE multi-target extraction with OF/IN qualifier filtering MOVE X TO A B C now produces write edges for all targets, not just the first. extractMoveTargets() helper handles OF/IN qualified names (WS-NAME OF WS-RECORD -> target is WS-NAME), subscript stripping (WS-TABLE(I) -> WS-TABLE), and MOVE_SKIP filtering on targets. Data model: CobolRegexResults.moves.to:string -> targets:string[] MOVE CORRESPONDING stays single-target per COBOL standard. Processor MOVE loop now iterates move.targets. * feat(cobol): COPY IN/OF library, pseudotext REPLACING, dynamic CALL, PERFORM TIMES, CICS MAP unquoted Phase 2B: COPY ... IN/OF library-name now captured as metadata in CopyResolution (IN and OF are synonyms per COBOL-85 standard). Phase 2C: COPY REPLACING ==pseudotext== support. Tokenizer handles ==...== delimiters alongside "quoted" strings. Pseudotext forces EXACT type. Two-pass applyReplacing: first pass handles space-containing/ non-identifier pseudotext via global string replace; second pass handles identifier-level LEADING/TRAILING/EXACT. New test file cobol-copy-expander.test.ts with 10 tests. Phase 2E: PERFORM WS-COUNT TIMES no longer produces a false-positive perform target (checks for TIMES keyword after captured identifier). Phase 2F: Dynamic CALL via data item (CALL WS-PROG-NAME without quotes) now emits a CodeElement annotation node with description 'dynamic-call' instead of silently ignoring. Adds isQuoted:boolean to call results. Phase 3A: CICS MAP(WS-MAP-NAME) unquoted identifiers now captured. Phase 3B: Normalized || to ?? in copy-expander (done in Phase 1A). * feat(cobol): nested program support — capture multiple PROGRAM-IDs per file Phase 2D: The state machine now captures all PROGRAM-IDs, not just the first. The primary program name stays in programName; additional nested programs go into nestedPrograms[]. The processor creates separate Module nodes for each nested program, contained by the outer module, and registers them in moduleNodeIds for cross-program CALL resolution. Paragraphs/data items are not yet scoped per-program (attributed to the outer module) — full per-program scoping is a future enhancement that requires END PROGRAM boundary tracking in the state machine. * test(cobol): expand integration tests for all new language features New fixtures: - NESTED.cbl — two PROGRAM-IDs (OUTER-PROG, INNER-PROG) for nested program support testing - COPYLIB.cpy — copybook for pseudotext REPLACING test target Modified fixtures: - CUSTUPDT.cbl — single-quoted ENTRY 'ALTENTRY', multi-target MOVE (WS-AMT TO FIELD-A FIELD-B), dynamic CALL WS-PROG-NAME, COPY COPYLIB with pseudotext REPLACING, LINKAGE SECTION with LS-PARAM - RPTGEN.cbl — PERFORM WS-COUNT TIMES (false-positive guard), unquoted MAP(WS-MAP-NAME), additional data items WS-COUNT WS-MAP-NAME Integration test rewritten with 62 exact assertions covering: - 5 Module, 17 Function, 33 Property, 9 CodeElement, 2 Constructor nodes - Nested program containment (OUTER-PROG -> INNER-PROG) - Dynamic CALL annotation (CodeElement with cobol-dynamic-call) - Multi-target MOVE (UPDATE-BALANCE: 2 reads, 3 writes) - Single-quoted ENTRY (ALTENTRY under CUSTUPDT) - PERFORM TIMES guard (WS-COUNT not in CALLS) - Orphan unresolved edge removal (zero -unresolved edges) - Grand totals: 21 CALLS, 68 CONTAINS, 2 IMPORTS, 10 ACCESSES * fix(cobol): pseudotext REPLACING now applies correctly via isPseudotext flag Root cause: ==PREFIX-== matched /^[A-Z][A-Z0-9-]*$/i (trailing hyphens allowed), routing it to the second-pass EXACT identifier match where PREFIX-RECORD !== PREFIX- failed silently. Fix: Propagate isPseudotext from parseReplacingClause to CopyReplacing interface, then use it in applyReplacing first-pass condition to force global string replacement for all pseudotext entries regardless of whether the content looks like an identifier. Result: COPY COPYLIB REPLACING ==PREFIX-== BY ==WS-==. now correctly transforms PREFIX-RECORD → WS-RECORD, PREFIX-CODE → WS-CODE, etc. * refactor(cobol): per-program scoping via boundary tracking + line-range grouping State machine changes (minimal, ~30 lines): - Add RE_END_PROGRAM regex for END PROGRAM program-name. detection - Replace nestedPrograms[] with programs[] containing startLine/endLine/ nestingDepth metadata for each PROGRAM-ID in the file - Reset division/section/paragraph state on new PROGRAM-ID boundary - EOF finalization flushes remaining stack entries (single-program files) - Programs sorted by startLine (outer before inner) Processor changes: - Uses programs[] with line-range containment to find enclosing parent Module for nested programs (replaces hardcoded nestedParent logic) - programModuleIds Map tracks Module node IDs per program name Fixture: NESTED.cbl now includes END PROGRAM lines for both programs. Integration test: PREFIX-* Property nodes now correctly appear as WS-* after the pseudotext REPLACING fix from the previous commit. * feat(cobol): free-format COBOL support (>>source free) Auto-detects >>SOURCE FREE directive in the first 500 chars and switches to free-format line processing: - No column-position rules (cols 1-6 are program text, not sequence area) - Comments use *> prefix instead of col 7 indicator - No continuation line indicator - Strip inline *> comments - Skip >>SOURCE directive lines preprocessCobolSource() skips col-1-6 stripping for free-format files. Paragraph/section regexes relaxed from fixed 7-space prefix to flexible whitespace with case-insensitivity (/^\s*([A-Z][A-Z0-9-]+)\.\s*$/i). EXCLUDED_PARA_NAMES expanded with COBOL verbs (GOBACK, END-READ, etc.) to prevent false-positive paragraph detection in free-format. Also fixes: entry-point-scoring.ts crash when language is 'cobol' (MERGED_ENTRY_POINT_PATTERNS[language] was undefined → optional chaining). Benchmark on ACAS 3.01 (268 GnuCOBOL free-format programs, 10MB): - Before: 407 nodes, 393 edges (near-empty, only file nodes) - After: 4,297 nodes, 3,612 edges, 542 clusters, 11 flows * fix(cobol): relax data item regexes for free-format (^\s+ to ^\s*) RE_FD, RE_DATA_ITEM, RE_ANONYMOUS_REDEFINES, and RE_88_LEVEL all used ^\s+ which requires at least 1 leading space. In free-format mode, lines are trimmed before processing, so data items like "01 WS-FIELD PIC X." have no leading whitespace after trimming. Changed to ^\s* (zero or more spaces) which works for both fixed-format (indented lines still have spaces) and free-format (trimmed lines). ACAS benchmark (268 GnuCOBOL programs): - Before: 4,297 nodes, 3,612 edges (paragraphs only) - After: 13,832 nodes, 8,615 edges (+ data items, FDs, 88-levels) * feat(cobol): 100% structural feature coverage — GO TO, SCREEN, SD/RD, SORT, SEARCH, CANCEL, Level 66 New extractions: GO TO (CALLS edges), SCREEN SECTION data items, SD/RD alongside FD (Record nodes), SORT/MERGE USING/GIVING (ACCESSES), SEARCH (ACCESSES), CANCEL (CALLS), Level 66 RENAMES (Property), IS EXTERNAL/IS GLOBAL (Property description enrichment). ACAS: 13,951 nodes | 13,193 edges | 685 clusters | 150 flows (+53% edges from new GO TO/SORT/SEARCH/CANCEL extractions) * feat(cobol): enriched CICS extraction — file I/O, dynamic PROGRAM, queues, HANDLE ABEND EXEC CICS blocks now extract: - FILE/DATASET clause: captures VSAM file name (literal or data item ref) for READ/WRITE/REWRITE/DELETE/STARTBR/READNEXT/READPREV → ACCESSES edges - PROGRAM clause: now handles unquoted variable references (dynamic CICS program transfer) → CodeElement annotation with cics-dynamic-program reason - QUEUE clause: captures TS/TD queue names from WRITEQ/READQ → ACCESSES edges - LABEL clause: captures HANDLE ABEND error handler targets → CALLS edges - TRANSID: now handles unquoted variable references CodeElement descriptions enriched with all captured fields (map, program, transid, file, queue, label). CardDemo benchmark: +49 nodes, +33 edges from enriched CICS extraction. * feat(cobol): complete CICS command extraction — all 7 expert recommendations From COBOL expert agent analysis: 1. ENDBR added to isRead file command list 2. LOAD added to PROGRAM edge commands (alongside LINK/XCTL) 3. Two-word commands expanded: WRITEQ/READQ/DELETEQ TS/TD, HANDLE ABEND/AID/CONDITION, START TRANSID 4. Queue reason differentiated: cics-queue-read/-write/-delete 5. RETURN/START TRANSID → CALLS edges to synthetic <transid> target 6. MAP → ACCESSES edges for screen traceability 7. INTO/FROM data fields extracted → ACCESSES edges to data items Also: dataItemMap built before CICS block processing (was declared after), CodeElement descriptions enriched with all captured CICS fields. * test(cobol): strict exhaustive integration tests with exact edgeSet assertions Every edge reason has exact sorted pair assertions via edgeSet(), not just counts. Any change to extraction that adds, removes, or reorders edges will produce a precise, descriptive failure. Updated RPTGEN.cbl fixture with: - GO TO EXIT-PARAGRAPH, SORT USING/GIVING, SEARCH table - EXEC CICS READ FILE INTO, WRITEQ TS QUEUE FROM, SEND MAP FROM - EXEC CICS HANDLE ABEND LABEL, RETURN TRANSID, XCTL PROGRAM(variable) - ABEND-HANDLER and EXIT-PARAGRAPH paragraphs 46 tests covering 24 CALLS + 79 CONTAINS + 18 ACCESSES + 2 IMPORTS edges across 15 distinct edge reason codes, all with exact sorted pair lists. * fix(cobol): address 5 findings from second Claude review (compiler front-end perspective) Finding #2: Numeric sequence numbers now stripped (changed /[^0-9 ]/ to /\S/ in preprocessCobolSource). Lines like "000100 MAIN-PARAGRAPH." now have cols 1-6 blanked so paragraph regex matches correctly. Finding #11: JCL in-stream PROC ordering fixed — pre-register all PROCs into moduleNames before step processing. Steps that EXEC a PROC defined later in the same file now get CALLS edges. Finding #A: PROCEDURE DIVISION USING no longer captures calling-convention keywords (BY, VALUE, REFERENCE, CONTENT, ADDRESS, OF) as parameter names. Finding #C: SORT/MERGE USING/GIVING now captures ALL file references (multi-file), not just the first. Changed from single-match to section extraction with split. Finding #D: Section headers no longer set currentParagraph, preventing PERFORM caller misattribution to Namespace instead of Function nodes. * fix(cobol): address code review findings — ReDoS fix, perf, cleanup P1 CRITICAL — ReDoS in SORT USING/GIVING: Replaced nested-quantifier regex with safe indexOf+substring+split approach. No backtracking possible on crafted input. P2 — readCopy O(M) linear scan: Added copybookByPath reverse Map for O(1) path-to-content lookup. P3 — Dead code removal: Deleted unused RE_SORT_USING and RE_SORT_GIVING constants. P3 — EXCLUDED_PARA_NAMES simplification: Replaced 20 END-* entries with startsWith('END-') prefix check. Auto-covers future END-* verbs. P3 — Misplaced JSDoc on removeRelationship: Fixed comment that described removeNodesByFile instead. Added missing JSDoc to removeNodesByFile. Review agents: architecture-strategist, performance-oracle, security-sentinel, code-simplicity-reviewer. * refactor: add Cobol to SupportedLanguages with parseStrategy: standalone New languages/cobol.ts — standalone regex processor provider with no-op tree-sitter fields. Declares parseStrategy: 'standalone' to distinguish from tree-sitter-based languages. Added parseStrategy: 'tree-sitter' | 'standalone' to LanguageProviderConfig for languages that use their own processor instead of tree-sitter. Removed all 11 'cobol' as any casts — now uses SupportedLanguages.Cobol. Added empty Cobol entries to entry-point-scoring and framework-detection. * fix(cobol): 5 fixes from third Claude review + 3 regression tests Fixes: - Line numbers now 1-indexed in fixed-format (was 0-indexed, off-by-one in jump-to-definition links) - Copybook content preprocessed before COPY expansion (sequence numbers and patch markers in copybooks no longer survive into expanded source) - ENTRY USING filters calling-convention keywords (BY, VALUE, REFERENCE, CONTENT, ADDRESS, OF) — same fix as PROCEDURE DIVISION USING - SORT/MERGE trailing period stripped from USING/GIVING file tokens - Paragraph exclusion uses exact match for SECTION/DIVISION (was substring match that excluded valid names like CROSS-SECTION-ANALYSIS) USING_KEYWORDS moved to module scope for reuse by both PROCEDURE DIVISION USING and ENTRY USING handlers. New unit tests: - ENTRY USING BY VALUE filtering - Paragraph names containing SECTION not excluded - Numeric sequence numbers stripped enabling paragraph detection * fix(cobol): address 6 findings from fourth Claude review + tests Fourth review findings fixed: - New #IV: PERFORM TIMES guard uses perfMatch.index instead of line.indexOf (prevents wrong match when target appears earlier in line) - New #V: 88-level condition values now handle single-quoted literals ('Y' no longer stored with embedded quotes) - New #I: CANCEL edges use two-pass resolution like CALL (no longer silently dropped when target indexed after source) - New #3: Multi-line SORT/MERGE accumulation — sortAccum state variable accumulates lines until period, then extracts USING/GIVING from full statement (95% of production SORT statements span multiple lines) - New #II: PROCEDURE DIVISION USING on split lines — pendingProcUsing flag defers parameter capture to next line if USING not on same line - New #6 (prior): EXCLUDED_PARA_NAMES exact match for SECTION/DIVISION Updated fixture: RPTGEN.cbl SORT now uses multi-line format with GIVING on separate line (period-terminated). New sort-giving integration test. ACCESSES total: 18 → 19 (new sort-giving edge from multi-line capture). * fix(cobol): address 4 findings from fifth Claude review Finding #B (5 reviews old): Section/paragraph node IDs now include enclosing program name to prevent collision when nested programs share section/paragraph names. New findOwningProgramName() helper uses programs[] line ranges to find the innermost enclosing program. Finding #α: pendingProcUsing now reset in the if(procUsingMatch) branch (was only set in else branch, could leak across nested programs). Finding #β: RE_CALL_DYNAMIC uses negative lookbehind (?<![A-Z0-9-]) to prevent false-positive on compound identifiers like WS-CALL OCCURS. Finding #γ: sortAccum flushed at EOF (parallel to flushSelect and pendingFdName EOF cleanup). Prevents silent loss of SORT USING/GIVING relationships in truncated files. * fix(cobol): address findings from reviews 5+6 with full test coverage Review 5 fixes: - #α: pendingProcUsing reset in if(procUsingMatch) branch - #β: RE_CALL_DYNAMIC negative lookbehind prevents WS-CALL false positive - #γ: sortAccum flushed at EOF for truncated files - #B: Section/paragraph IDs include owning program name Review 6 fixes: - #P: sectionNodeIds/paraNodeIds maps use program-scoped keys (PROGNAME:NAME). New scopedParaLookup/scopedCallerLookup helpers. findContainingSection updated with programs parameter. - #Q: RETURNING added to USING_KEYWORDS for COBOL 2002+ - #R: RE_PERFORM matches both THRU and THROUGH via alternation New unit tests (6): - PERFORM THROUGH captures thruTarget - PROCEDURE DIVISION USING RETURNING filters keyword - RE_CALL_DYNAMIC no false-match on WS-CALL compound identifier - Multi-line SORT captures USING/GIVING from continuation lines - PROCEDURE DIVISION USING on split line via pendingProcUsing - Copybook preprocessing strips sequence numbers * fix(cobol): address findings from seventh Claude review + 3 tests Review 7 fixes: - #i: findContainingSection only updates best when lookup succeeds (prevents undefined overwriting valid parent section) - #ii: RE_PROC_SECTION handles segment numbers (SECTION 30.) - #III: procedureUsing now stored per-program on boundary stack entries, propagated to programs[] output. Inner programs no longer overwrite outer program's parameters. - #δ: Dynamic CANCEL (CANCEL variable) now creates CodeElement annotation node, matching dynamic CALL behavior. RE_CANCEL_DYNAMIC with negative lookbehind. cancels[] gains isQuoted field. - #Q: RETURNING added to USING_KEYWORDS (already in prev commit) - #R: PERFORM THROUGH already fixed (THRU|THROUGH alternation) New unit tests: - Nested programs carry per-program procedureUsing - SECTION with segment number detected - Dynamic CANCEL via data item captured with isQuoted=false * feat(cobol): link PROCEDURE DIVISION USING to LINKAGE data items + close 4 findings Finding #10 FIXED: procedureUsing parameters now create ACCESSES edges with reason 'cobol-procedure-using' from Module to matching LINKAGE SECTION Property nodes. This exposes the program's parameter contract in the graph (e.g., AUDITLOG → LS-CUST-ID, AUDITLOG → LS-AMOUNT). Findings closed by expert agent consensus: - #6 COPY IN library: WONTFIX — captured metadata, no universal library-to-directory mapping exists. Field costs nothing and is useful for library queries. - #14 SQL DELETE: WONTFIX — DB2 requires FROM; existing FROM pattern handles it. Bare DELETE would risk false positives. - #E OCCURS DEPENDING ON: WONTFIX — runtime sizing concern, not structural. The static occurs count is sufficient for indexing. All 39 findings from 7 Claude reviews now resolved or closed. * fix(cobol): resolve 48 review findings across 9 review cycles Ninth deep review resolved all remaining COBOL parser gaps identified by 5 specialist agents (COBOL expert, architecture strategist, TypeScript reviewer, security sentinel, code simplicity reviewer). Fixes (P1 — critical): - SELECT OPTIONAL now correctly skips OPTIONAL keyword (C1) - RETURNING params excluded from PROCEDURE DIVISION USING list (C7) - SORT GIVING no longer captures clause keywords as file names (C5) - Extract flushSort() helper eliminating 40-line duplication (S2) - Flush unclosed EXEC blocks at EOF matching SORT/SELECT pattern (S3) - Guard undefined map key in jcl-processor moduleNames (S1) - Add MAX_TOTAL_EXPANSIONS=500 to prevent exponential COPY breadth (S4) Fixes (P2 — important): - Quote-aware stripInlineComment for | and *> in string literals (C2+C3) - Fixed-format literal continuation now handles quoted strings (C6) - PROGRAM-ID detected regardless of division state for siblings (C9) Fixes (P3 — cleanup): - EXEC SQL INTO restricted to INSERT INTO to avoid FETCH false-pos (C8) - Copy expander line numbers fixed from 0-based to 1-based (C11) - Remove dead code: inInStreamProc, fileIsLiteral, expansionDepth (S7-S10) Also fixes 8th-review findings: nested program CONTAINS attribution, multi-PERFORM on same line, INPUT/OUTPUT PROCEDURE IS in SORT, GO TO DEPENDING ON multi-target, MOVE CORR abbreviation, per-program procedureUsing ACCESSES edges. Tests: 145 COBOL tests passing (59 integration + 86 unit) Benchmarks: CardDemo 12,323 nodes/8,893 edges (7.4s) ACAS 14,016 nodes/15,452 edges (9.3s, -9% faster) * docs(cobol): update documentation for ninth review cycle fixes Update all 4 COBOL documentation files to reflect the 16 fixes from the ninth review cycle: - regex-extraction.md: quote-aware comment stripping, SELECT OPTIONAL, RETURNING exclusion, SORT_CLAUSE_NOISE filter, flushSort() helper, GO TO multi-target, PROGRAM-ID division-independent detection - copy-expansion.md: MAX_TOTAL_EXPANSIONS=500 breadth guard, 1-based line numbers, removed expansionDepth/warnedCircular param - deep-indexing.md: GO TO DEPENDING ON, INPUT/OUTPUT PROCEDURE IS, MOVE CORR edge reasons, INSERT INTO restriction, literal continuation - performance.md: updated benchmarks (CardDemo 12,323n/8,893e/7.4s, ACAS 14,016n/15,452e/9.3s), COPY breadth guard * fix(cobol): resolve 10th review findings — nested program edge attribution Fix 6 findings from the 10th review (PR #498 comment #4132201110): #A+#F: All CALL/CANCEL/CICS/ENTRY/SQL/SEARCH/file-declaration edges now use owningModuleId() for nested program attribution instead of the outer program's parentId. Added helper function owningModuleId() to centralize the pattern. #B: Added USING and GIVING to SORT_CLAUSE_NOISE set to prevent MERGE USING + OUTPUT PROCEDURE from capturing clause keywords as file names. #C: INPUT/OUTPUT PROCEDURE regex now captures optional THRU/THROUGH range end paragraph, mirroring RE_PERFORM's THRU support. #D: scopedCallerLookup fallback now uses programModuleIds.get(pgm) instead of parentId, so PERFORM/MOVE/GOTO in nested programs with unresolvable paragraphs fall back to the correct inner module. #E: pendingProcUsing only set when PROCEDURE DIVISION line is NOT period-terminated, preventing false USING expectation. Tests: 145 passing | TypeScript clean * fix(cobol): resolve 10th review findings — nested program edge attribution Fix 6 findings from the 10th review (PR #498 comment #4132201110): #A+#F: All CALL/CANCEL/CICS/ENTRY/SQL/SEARCH/file-declaration edges now use owningModuleId() for nested program attribution instead of the outer program's parentId. Added helper function owningModuleId() to centralize the pattern. #B: Added USING and GIVING to SORT_CLAUSE_NOISE set to prevent MERGE USING + OUTPUT PROCEDURE from capturing clause keywords as file names. #C: INPUT/OUTPUT PROCEDURE regex now captures optional THRU/THROUGH range end paragraph, mirroring RE_PERFORM's THRU support. #D: scopedCallerLookup fallback now uses programModuleIds.get(pgm) instead of parentId, so PERFORM/MOVE/GOTO in nested programs with unresolvable paragraphs fall back to the correct inner module. #E: pendingProcUsing only set when PROCEDURE DIVISION line is NOT period-terminated, preventing false USING expectation. Tests: 145 passing | TypeScript clean * fix(cobol): resolve 11th review findings — final nested program + multi-CALL gaps #1: scopedCallerLookup(null) now uses owningModuleId(lineNum) instead of parentId, fixing PERFORM/MOVE/GOTO before first paragraph in nested programs. #2+#3: CALL and CANCEL extraction now uses matchAll (global flag) to capture multiple occurrences on the same line. Dynamic CALL/CANCEL checked independently instead of in else branch. #4: SORT/MERGE ACCESSES edge IDs now use owningModuleId(sort.line) instead of parentId for nested program correctness. #5: preprocessCobolSource free-format detection now uses first 10 lines (consistent with extractCobolSymbolsWithRegex threshold). #6: EXCLUDED_PARA_NAMES expanded with DISPLAY, ACCEPT, WRITE, READ, REWRITE, DELETE, OPEN, CLOSE, RETURN, RELEASE, SORT, MERGE to prevent false-positive paragraph detection on isolated verbs. Also removed unused GraphNode import from cobol-processor.ts. Tests: 145 passing | TypeScript clean * docs(cobol): deepened full language coverage plan with research findings 3 research agents analyzed Phase 1-2 features and graph value ranking. Key findings: cobol-call-using is #1 edge type (9.2/10); multi-line accumulation is dominant challenge; DECLARATIVES is lowest-risk Phase 2 item; SET TO TRUE covers 80-90% of SET usage. * feat(cobol): implement Phase 1 — high-value data flow edges 4 new extraction features that create new ACCESSES and IMPORTS edges: 1.1: EXEC SQL INCLUDE -> IMPORTS edges with reason 'sql-include' Handles unquoted (SQLCA), quoted ('DBRMLIB.MEMBER'), and underscored (CUST_TBL_DCL) member names. 1.2: CALL USING parameter extraction -> ACCESSES edges Extracts parameters from CALL USING clause, filtering BY/REFERENCE/ CONTENT/VALUE/ADDRESS/OF/LENGTH/OMITTED keywords. Creates 'cobol-call-using' ACCESSES edges (graph value: 9.2/10). 1.4: OCCURS DEPENDING ON -> ACCESSES edges with reason 'cobol-depends-on' Extended OCCURS regex captures DEPENDING ON field with subscript stripping. Creates dependency edge from table to controlling field. 1.5: VALUE clause for standard data items Extracts VALUE from data item clauses: quoted strings with type prefix (X/N/G/B), ALL literals, numerics (incl negative/decimal), and figurative constants. Populates Property node values. Tests: 145 passing (+2 ACCESSES from CALL USING) | TypeScript clean * feat(cobol): implement Phase 2 — DECLARATIVES, SET, INSPECT, EXEC DLI 4 new extraction features for error handling, data flow, and IMS/DB: 2.1: EXEC DLI (IMS/DB) -> CodeElement + ACCESSES edges Accumulates EXEC DLI blocks like EXEC SQL. Parses DLI verbs (GU, GN, ISRT, REPL, DLET, CHKP, SCHD, TERM). Extracts SEGMENT, PCB, INTO/FROM, PSB. Creates dli-{verb} ACCESSES edges to <ims>:segment Record nodes. 2.2: DECLARATIVES / USE AFTER EXCEPTION -> ACCESSES edges Tracks inDeclaratives state. Detects USE AFTER STANDARD EXCEPTION ON file-name. Creates cobol-error-handler ACCESSES edge from handler section to file Record. 2.3: SET statement -> ACCESSES edges Detects SET TO TRUE (80-90% of SET usage) and SET index TO/UP BY/DOWN BY. Creates cobol-set-condition / cobol-set-index write edges + cobol-set-read for identifier values. 2.4: INSPECT -> ACCESSES edges with multi-line accumulator Accumulates INSPECT until period (like SORT). Extracts inspected field + tally counters. Creates cobol-inspect-read/write/tally edges. Form detection: tallying/replacing/converting/combined. Preprocessor: 1398 -> 1597 LOC (+199). Tests: 145 passing. * feat(cobol): implement Phase 3 — completeness fixes 6 partial features fixed to first-class support: 3.1: CALL RETURNING -> ACCESSES write edge (cobol-call-returning) 3.2: SELECT OPTIONAL flag preserved in FileDeclaration + Record node 3.3: ALTERNATE RECORD KEY extraction (matchAll for multiple keys) 3.4: COMMON attribute on nested programs (RE_PROGRAM_ID extended) 3.5: IS EXTERNAL / IS GLOBAL as first-class boolean properties (removed usage string hack) 3.6: AUTHOR / DATE-WRITTEN mapped to Module node description Tests: 145 passing | TypeScript clean * feat(cobol): implement Phase 4 — INITIALIZE + metadata completeness 4.1: INITIALIZE statement -> ACCESSES write edge (cobol-initialize) 4.2: DATE-COMPILED and INSTALLATION paragraphs extracted and mapped to Module node description alongside existing AUTHOR/DATE-WRITTEN All 4 plan phases complete. Coverage: ~95% (up from 71.9%). Tests: 145 passing | TypeScript clean * test(cobol): add 24 unit tests for Phase 1-4 features Coverage for all new extraction features: Phase 1 (8 tests): - EXEC SQL INCLUDE (unquoted, quoted, underscored) - CALL USING (simple, mixed modes, ADDRESS OF, OMITTED) - CALL RETURNING - OCCURS DEPENDING ON - VALUE clause (string, numeric, figurative constant) Phase 2 (10 tests): - EXEC DLI GU/ISRT/SCHD (verb, segment, PCB, INTO, FROM, PSB) - DECLARATIVES USE AFTER EXCEPTION (single + multiple sections) - SET TO TRUE, SET index UP BY - INSPECT TALLYING, INSPECT REPLACING Phase 3-4 (6 tests): - SELECT OPTIONAL flag - ALTERNATE RECORD KEY - PROGRAM-ID IS COMMON - IS EXTERNAL / IS GLOBAL booleans - INITIALIZE extraction - Full programMetadata (AUTHOR, DATE-WRITTEN, DATE-COMPILED, INSTALLATION) Total: 168 tests passing (145 + 24 - 1 removed duplicate) * fix(cobol): use /\r?\n/ split for Windows CRLF compatibility All 4 COBOL source files now split on /\r?\n/ instead of '\n' to handle CRLF line endings on Windows. Previously, trailing \r in lines caused RE_GOTO's $ anchor to fail on multi-line GO TO DEPENDING ON statements, producing only 1 goto edge instead of 4. Files fixed: cobol-preprocessor.ts (2 sites), cobol-processor.ts, jcl-parser.ts, cobol-copy-expander.ts Tests: 168 passing | TypeScript clean * fix(cobol): resolve 12th review — dynamic CALL/CANCEL dedup + trailing anchors #1+#2: Removed incorrect hasQuotedCall/hasQuotedCancel deduplication guards. RE_CALL_DYNAMIC and RE_CANCEL_DYNAMIC require [A-Z] after CALL/CANCEL, so they CANNOT match quoted targets — the guards were both unnecessary and actively harmful, suppressing dynamic CALL/CANCEL in ON EXCEPTION patterns. #3+#5: Changed RE_CALL_DYNAMIC and RE_CANCEL_DYNAMIC trailing anchor from (?:\s|\.) to (?=\s|\.|$) (lookahead). The consuming anchor failed when the identifier was the last token on a physical line. Tests: 168 passing | TypeScript clean * feat(cobol): add CALL accumulator + fix SORT double-statement (#4, #6) Finding #4: Multi-line CALL USING accumulator Added callAccum state variable that accumulates CALL statements spanning multiple physical lines until period or END-CALL is found. Uses flushCallAccum() to re-extract CALL target + USING parameters from the full accumulated statement. This fixes the silent loss of ACCESSES parameter edges when USING appears on lines after CALL. Finding #6: SORT double-statement on same line After flushSort(), the code now falls through to re-check the current line for a new SORT/MERGE start (was previously blocked by the sortAccum === null check evaluating before flushSort ran). Also fixed: used non-global regex for CALL detection test to avoid the classic global regex .test() lastIndex bug. Tests: 168 passing (+1 ACCESSES from multi-line CALL USING) * fix(cobol): resolve 13th review — CICS LOAD, USING extraction, file scoping #1: CICS LOAD unresolved edge no longer silently deleted in second pass. Changed narrow cics-link/cics-xctl check to catch-all pattern: rel.reason?.startsWith('cics-') && rel.reason.endsWith('-unresolved') #2: flushCallAccum USING extraction now stops before COBOL statement verbs (INSPECT, SEARCH, SORT, MERGE, DISPLAY, ACCEPT, MOVE, PERFORM, GO TO, CALL, IF, EVALUATE). Prevents absorbing adjacent statements as false USING parameters in legacy pre-COBOL-85 code without END-CALL. #3: CICS FILE Record nodes now globally-scoped (<cics-file>:FILENAME) instead of per-file-scoped. Enables cross-program CICS file access analysis, consistent with SQL table scoping (<db>:TABLE). #4: callAccum pre-check regex now has (?<![A-Z0-9-]) lookbehind to prevent false activation on compound identifiers like WS-CALL-FLAG. Tests: 168 passing | TypeScript clean * fix(cobol): resolve 14th review — callAccum false paragraph + Area A guard #1: callAccum continuation lines now check for COBOL statement verb starts (GO TO, PERFORM, MOVE, etc.) and paragraph/section headers. If detected, the CALL is flushed as-is and the line processed normally — prevents false paragraph detection and currentParagraph corruption from lines like "WS-ADDR." being treated as paragraphs. #4: callAccum pre-check now guarded by currentDivision === 'procedure' to prevent unnecessary activations in DATA DIVISION. #5: Fixed-format paragraph detection now rejects lines with >7 leading spaces (Area B indentation) as paragraph candidates. Paragraph names in fixed-format must start in Area A (col 8-11, max 7 spaces). Free-format mode is unaffected. Tests: 168 passing | TypeScript clean * fix(cobol): resolve 15th review — callAccum Area A + verb boundary fixes #A: Column-position-aware paragraph detection in callAccum flush. #B: inspectAccum early-flush on paragraph/section/verb headers. #C: Verb boundary \b → (?:\s|$) prevents MOVE-COUNT false flush. * test(cobol): add 17 edge-case regression tests + fix USING verb boundary 17 new tests covering all recurring review patterns: Multi-line CALL USING (7 tests): - Parameters on separate continuation lines (IBM mainframe style) - No absorption of INSPECT/GO TO/paragraphs following CALL - END-CALL scope terminator - Hyphenated identifiers (MOVE-COUNT) not triggering false flush - Dual quoted+dynamic CALL on same line (ON EXCEPTION) Nested program attribution (2 tests): - CALL in inner program within inner line range - PERFORM before first paragraph has null caller CRLF compatibility (1 test): - GO TO DEPENDING ON with \r\n line endings Area A paragraph detection (2 tests): - Area B (>7 spaces) rejected; Area A (7 spaces) accepted SORT/MERGE (1 test): COLLATING SEQUENCE keywords not captured PROCEDURE USING (2 tests): RETURNING excluded, period-terminated Comment stripping (1 test): pipe in quoted string preserved SELECT OPTIONAL (1 test): correct file name, not OPTIONAL keyword Bug fix: USING extraction regex verb terminators changed from \bVERB\b to \bVERB(?=\s|$) in flushCallAccum — prevents truncation on hyphenated identifiers like MOVE-COUNT, PERFORM-LIMIT. Total: 185 tests passing * test(cobol): add 32 comprehensive edge-case regression tests 13 new describe blocks covering all extraction features: - EXEC DLI: no-SEGMENT, multi-line accumulation (2 tests) - SET: multiple targets, DOWN BY, TO numeric (3 tests) - INSPECT: CONVERTING, multiple counters, tallying-replacing, paragraph flush during accumulation (4 tests) - DECLARATIVES: no-STANDARD keyword, I-O mode, post-END paragraphs (3) - COPY REPLACING: pseudotext deletion ==OLD== BY ==== (1 test) - VALUE: hex literal, negative numeric, ALL literal (3 tests) - OCCURS: TO range, fixed-size without DEPENDING ON (2 tests) - Dynamic CALL/CANCEL: end-of-line, multiple CANCELs (3 tests) - EXEC SQL: INCLUDE skips tables, SELECT INTO host vars, host variable extraction (3 tests) - INITIALIZE: target and caller context (1 test) - Nested programs: sibling scoping, PROGRAM-ID without ID DIV (2) - EXEC EOF flush: unclosed EXEC SQL flushed (1 test) - Multi-PERFORM: IF/ELSE dual PERFORM on single line (1 test) - IS EXTERNAL: USAGE not polluted by external flag (1 test) Total: 215 tests passing * fix(cobol): resolve 16th review — CANCEL in CALL block + USING boundary #1: flushCallAccum now extracts CANCEL statements from within CALL ON EXCEPTION blocks. Adds RE_CANCEL + RE_CANCEL_DYNAMIC matchAll passes alongside existing CALL extraction. #2: Added \bCANCEL(?=\s|$) to USING lookahead regex to prevent CANCEL keyword being captured as false USING parameter. #3: Multi-line CALL start now returns immediately to prevent the CALL start line from simultaneously feeding sortAccum/inspectAccum. #6: Division transitions now flush all active accumulators (callAccum, sortAccum, inspectAccum) to prevent state leakage across programs. Also added CANCEL to callAccum flush trigger verb list. Tests: 215 passing | TypeScript clean * refactor(cobol): extract shared verb constants + resolve 17th review Extract COBOL_STATEMENT_VERBS, RE_STATEMENT_VERB_START, and RE_USING_PARAMS as shared constants — eliminates 4 duplicated 25-verb regex patterns. 17th review: #1 flushCallAccum before EXEC entry, #2 inspectAccum verb parity via shared constant. Tests: 215 passing | TypeScript clean * test(cobol): replace all fuzzy assertions with exact toBe checks Replaced 7 toBeGreaterThan/toBeLessThan/toBeGreaterThanOrEqual assertions with exact toBe values: - dataItems.length: >= 3 → toBe(3) - calls.length: >= 1 → toBe(1) - calls[0].line: range check → toBe(10) - programs[].startLine/endLine: comparison → exact values - innerA.endLine/innerB.startLine: comparison → exact values Also added 11 new edge-case tests (accumulator flush on EXEC/division transitions, free-format, CANCEL in CALL block, SORT THRU, verb flush, integration). 226 tests passing — zero fuzzy assertions remain. * fix(cobol): resolve 19th review + 15 accumulator flush tests Fixes: #1: END PROGRAM flushes callAccum/sortAccum/inspectAccum #2: PROGRAM-ID sibling path flushes all accumulators #3: Added COMPUTE/ADD/SUBTRACT/MULTIPLY/DIVIDE/STRING/UNSTRING to COBOL_STATEMENT_VERBS (now 32 verbs) Tests (15 new): - END PROGRAM flush: single + nested programs (2) - PROGRAM-ID sibling flush (1) - Arithmetic verb flush: COMPUTE/ADD/SUBTRACT/MULTIPLY/DIVIDE (5) - String verb flush: STRING/UNSTRING (2) - Arithmetic not captured as false USING params (1) - SORT flushed at END PROGRAM (1) - INSPECT flushed at END PROGRAM (1) - All with exact toBe assertions (2) Total: 239 tests passing | Zero fuzzy assertions * fix(cobol): resolve 20th review — INITIALIZE multi-target + 2 tests Finding 1: INITIALIZE now captures multiple targets with REPLACING clause keyword filtering.

* Initial plan * feat(SM-13): extract resolveFreeCall from resolveCallTarget Extract the free-function call resolution path into a dedicated `resolveFreeCall(calledName, filePath, ctx)` function that uses `lookupExact` + import-scoped resolution via `ctx.resolve()`. - Free function calls (foo()) now route through `resolveFreeCall` - Swift/Kotlin implicit constructors (User()) delegate to `resolveStaticCall` within `resolveFreeCall` - `resolveCallTarget` dispatches `callForm === 'free'` early, removing the inline freeFormHasClassTarget logic - S0 block simplified to only handle `callForm === 'constructor'` - Global (Tier 3) fallthrough preserved via ctx.resolve() until Phase 5 - 9 new unit tests for resolveFreeCall - All 163 unit tests pass, all 1199 integration resolver tests pass Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/c5f2e73a-259a-438c-b5c8-286b82e3c215 Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * chore: revert unrelated package-lock.json change Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/c5f2e73a-259a-438c-b5c8-286b82e3c215 Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix(SM-13): address PR #756 review findings on resolveFreeCall Addresses all 7 findings from the PR #756 review comment.

SM-13 duplicated the Swift extension same-name collision dedup block between `resolveCallTarget` and `resolveFreeCall` — two copies of identical 15-line logic with the same heuristic (`filePath.length` sort, Class/Struct-only, `length > 1` guard). Extract a single shared helper so the two sites cannot drift. Changes - New `dedupSwiftExtensionCandidates(candidates, tier)` helper defined alongside `tryOverloadDisambiguation`, with JSDoc documenting: - The Swift extension scenario it addresses - Why it is intentionally narrower than INSTANTIABLE_CLASS_TYPES (Class/Struct only, not Record — C#/Kotlin records don't exhibit the multi-file definition pattern, widening risks accidental dedup of legitimately distinct record types) - The return-null-on-no-match contract so callers can fall through - `resolveCallTarget` tail dedup (was lines 1593-1610): replaced with a single `dedupSwiftExtensionCandidates` call - `resolveFreeCall` tail dedup (was lines 1994-2012): same replacement - Net line count: -32 insertions, -9 deletions in the consumer sites, +36 for the shared helper + JSDoc Verification - `tsc --noEmit` clean - 3064 unit tests pass (including the R7 Swift dedup guard test added in the previous commit that exercises the full free-form retry chain through this helper) - 1766 integration tests pass - Zero regressions Follows-up on: #756 * docs(SM-13): address PR #756 final review — comment cleanup only Three documentation-only findings from the approval review. No behavior change, no new tests, no code path modifications. Finding #1 — stale line-number comment - The comment inside `resolveFreeCall` at the `hasClassTarget` site referenced "lines ~1994-2008" for the Swift extension dedup block. Those lines were the inlined pre-SM-13 version; the block has since been extracted to `dedupSwiftExtensionCandidates`. Replaced the line reference with the helper name so future readers don't chase dead line numbers. Finding #2 — fuzzy-widening asymmetry undocumented - `resolveFreeCall` intentionally has no `widenCache` parameter and no D2 fuzzy-widening pass (unlike `resolveCallTarget`'s member-call path). Added an explicit "Asymmetry vs `resolveCallTarget`" paragraph to the JSDoc so a caller comparing the two signatures knows the skipped pass is deliberate and tied to Phase 5. Finding #3 — constructor-form retry reasons undocumented - `resolveStaticCall` can return null for three distinct reasons (empty instantiable pool, homonym ambiguity, ownerless Constructor nodes). The retry below it unconditionally re-filters with `'constructor'` form, which is correct for all three but not obvious. Added a structured three-case comment enumerating each reason and linking (a) to the SM-12 null-route contract, (b) to the R7 dedup test, and (c) to the currently-uncovered ownerless- Constructor path (noted as a future test candidate). Verification - `tsc --noEmit` clean - 175 `resolveFreeCall` + `resolveStaticCall` + sibling tests pass (sanity check — no behavior change expected) - No regressions Follows-up on: #756 (comment) * test(SM-13): cover ownerless-Constructor retry + PHP free function Two low-severity test gaps from PR #756 review comment 4215739052 — previously addressed doc-only, now have concrete test coverage. Finding #3 low — ownerless-Constructor retry path (previously comment-only) - The retry after resolveStaticCall returns null handles three distinct null-return reasons. Cases (a) and (b) were already tested (Interface/ Trait null-route from SM-12, Swift shadowing dedup from R7). Case (c) — resolveStaticCall step-4 bailout when the tiered pool contains ownerless Constructor nodes — was only covered by a comment. - New test: Class + ownerless Constructor in tiered pool, callForm='free'. Exercises the full chain: 1. resolveStaticCall step 3 walks classCandidates via lookupMethodByOwner — ownerless Constructor not in methodByOwner, nothing found. 2. Step 4 detects Constructor in tiered pool, bails with null. 3. resolveFreeCall retry re-runs filterCallableCandidates with 'constructor' form, which prefers Constructor over Class per CONSTRUCTOR_TARGET_TYPES ordering. 4. Single survivor returned. - Asserts the Constructor node (not the Class) is the resolved target. Low — PHP free function coverage gap - The language coverage table in the same review flagged PHP free functions (top-level `function helper()` outside any class) as uncovered. Added a test mirroring the existing Go/Python/Rust/Java/ JS language tests — exercises the `.php` dispatch path for free calls. Ruby and C/C++ remain uncovered; deferred to a future round since those languages also have other gaps in the broader test file.

Fixes all 5 test failures (2 unit + 3 integration) and addresses 10 review findings from comment 4225312416. Critical fix — singleCandidate null-route guard The SM-19 dispatcher chained singleCandidate as an unconditional tail fallback for member calls with receiverTypeName. This bypassed the SM-10 R3 null-route contract: when the receiver type IS in the index but file/owner filtering produced zero matches, the old code returned null (genuine miss), but the new code fell through to singleCandidate (false-positive CALLS edge). Root cause: resolveMemberCallByFile returns null for two semantically different reasons — (1) type not found in the index at all, and (2) type found but no candidate matched after narrowing. The dispatcher treated both as "try the next fallback." The old resolveCallTarget exited the entire function on case 2. Fix: after the scoped resolvers both return null, check whether the receiver type resolves in the index. If it does (case 2), null-route — the scoped resolvers made the right decision. If it doesn't (case 1, e.g. PHP 'mixed', dynamic types), singleCandidate is the correct last resort. ctx.resolve is cached so the check is free. This fixes: - Unit: no heritageMap null-route test (was getting 1 edge, expects 0) - Integration: Rust c.trait_only() negative test - Integration: 3 PHP heritage + alias tests (singleCandidate correctly fires when the receiver type is not in the index) Performance (findings #1, #2, #3) - Thread pre-computed tiered result into resolveModuleAliasedCall via new tieredOverride parameter — eliminates the duplicate ctx.resolve call on every module-alias path. - Add countCallableCandidates helper that short-circuits at threshold without allocating an intermediate array — replaces the filterCallableCandidates(...).length > 1 allocation in skipMember. - resolveMemberCallByFile lookupCallableByName caching deferred to a follow-up (finding #2) — the fix requires threading widenCache through the file-scoped resolver which is a larger change. Code quality (findings #4, #5) - Remove dead code: redundant conditional in resolveMemberCallByFile where both branches returned null. - Move WidenCache type declaration from mid-file (between JSDoc blocks) to adjacent to CONSTRUCTOR_TARGET_TYPES with other type declarations.

When two homonym receiver types are both imported by the caller, the import-scoped tier no longer narrows and the owner/file resolvers see genuine ambiguity. The dispatcher null-routed silently, dropping valid CALLS edges. Fix: consult `resolveModuleAliasedCall` at the top of the typed-member branch so an active alias on `call.receiverName` picks the aliased file before the generic resolvers run. Finding 2 [medium] — Constructor dispatch lost overload disambiguation. When `resolveStaticCall` bails (ambiguous or ownerless Constructor pool) and the caller supplied `overloadHints` / `preComputedArgTypes`, the branch fell straight through to `singleCandidate` — which also bails on multiple same-arity survivors. Fix: between `resolveStaticCall` and `singleCandidate`, run constructor-filtered overload disambiguation on the tiered pool. Only engages when a narrowing signal is present; preserves SM-10 R3 null-route for genuinely ambiguous cases. Tests: - call-processor.test.ts: 3 new dispatcher-level regression tests covering real-homonym alias narrowing, constructor overload disambiguation with `argTypes`, and null-route control - symbol-table.test.ts: update `module alias homonyms` test which previously codified the Finding 1 regression; now asserts resolution to the aliased file's method Verification: 3191 unit + 2398 integration tests pass; tsc --noEmit clean; prettier clean. * refactor(SM-19): address code review findings with clean-code pass Code review on commit f424685 surfaced one P1 correctness regression and two P2 maintainability concerns. This commit closes all ten findings: P1 — Alias helper placement regression - resolveModuleAliasedCall now runs as a FALLBACK in the typed-member branch, after resolveMemberCall/resolveMemberCallByFile return null. Previously it short-circuited BEFORE scoped resolvers, leaking unrelated homonyms from the aliased file when a local var coincidentally matched a module alias. - Added type-file verification guard: alias narrowing only fires when the alias target file is among the receiver type's defining files. Prevents cross-type false positives and hardens SM-10 R3. P2 — Thin-dispatcher drift (roadmap Phase 3) - Extracted disambiguateByOverloadOrArgTypes shared helper. Centralizes the overloadHints → preComputedArgTypes precedence rule used by both member and constructor resolvers. - Folded constructor overload disambiguation into resolveStaticCall as step 4.5 (between the ambiguous-pool bail and the instantiable-class fallback). resolveStaticCall now accepts optional overloadHints / preComputedArgTypes symmetric with resolveMemberCallByFile. - Dispatcher's constructor branch returns to a 2-line delegation. - resolveMemberCallByFile now calls the shared helper instead of inlining the ternary. P2 — Missing test coverage - owner-scoped wins over alias narrowing (alias with unrelated target class must not override unique owner-scoped answer) - alias narrowing rejects unrelated target type (type-file guard) - alias fallthrough: receiverName not in alias map - alias fallthrough: alias target file has no matching method (overloadHints-for-constructor variant transitively covered via the extracted helper's member-path tests; direct dispatcher test deferred as it requires real OverloadHints fixture parsing) P3 — Clarity and durability - Stripped "Codex SM-19 Finding N" prefixes from comments. Replaced with durable explanations of WHY each guarded branch exists. - Added cross-reference comment at the tail-branch resolveModuleAliasedCall call site pointing to the typed-member branch usage. Verification: 3195 unit + 1766 resolver integration + 2398 full integration tests pass. tsc --noEmit clean. prettier clean.

* feat: shared resilient-fetch (retries + circuit breaker) Add a small, runtime-agnostic resilience layer in gitnexus-shared and migrate every backend HTTP outbound call (CLI, MCP, wiki LLM, web → backend) through it. Helpers (gitnexus-shared/src/integrations/): - retry.ts — withRetry(fn, opts) with caller-supplied retryability classification and full-jitter exponential backoff. - circuit-breaker.ts — closed/open/half-open per-process breaker with injectable clock, plus a keyed registry so callers targeting the same endpoint share state. - resilient-fetch.ts — composed wrapper: retries 5xx + 429 + retryable network throws, treats AbortSignal.timeout() and 4xx (other than 429) as terminal, honors Retry-After (capped at 30s), throws CircuitOpenError when the breaker opens. Migrations (no behaviour regression — all existing tests pass): - gitnexus/src/core/embeddings/http-client.ts (covers analyze + MCP query path) — replaces inline linear-backoff retry. - gitnexus/src/core/wiki/llm-client.ts — preserves Azure content-filter branch; resilientFetch handles 5xx/429. - gitnexus-web/src/services/backend-client.ts (fetchWithTimeout helper) — small retry budget (2 attempts, 250–1500 ms) so a dead local backend still fails fast for the user. - gitnexus-web/src/core/llm/settings-service.ts (OpenRouter model list). Deliberately not migrated: - gitnexus-web/src/services/backend-client.ts streamJob() — Server-Sent Events stream; the existing reconnect-with-Last-Event-ID logic is not unary-fetch shaped. - gitnexus-web/src/components/SettingsPanel.tsx checkOllamaStatus() — one-shot health probe; retrying delays the "Ollama not running" error rather than improving UX. 41 new helper tests cover backoff math, breaker state transitions, Retry-After parsing (delta-seconds + HTTP-date), 401/422 terminal classification, and breaker fail-fast on three exhausted retry batches. * fix(review): apply autofix feedback Address Claude's two MEDIUM blocking findings on PR #1448 plus the CodeQL SSRF false-positive flag. - backend-client `fetchWithTimeout` now uses `AbortSignal.timeout()` merged with the caller's signal via `AbortSignal.any()`. Timer-fired aborts surface as `DOMException(name='TimeoutError')` so resilientFetch routes them through the terminal-network branch (no retry, no breaker hit), instead of incrementing the breaker for user-side network slowness. - Method-aware retry budget in `fetchWithTimeout`: idempotent verbs (GET/HEAD/OPTIONS) keep the 2-attempt budget; POST/PATCH/PUT/DELETE default to single-attempt so a 5xx on `startAnalyze` cannot start a duplicate job. New `forceRetry` parameter for callers that know-idempotent mutations (e.g. DELETE of a known-deleted resource). - `resilient-fetch.ts` carries a documented suppression for CodeQL js/server-side-request-forgery on the inner fetch call. Every concrete caller passes a hardcoded URL constant or a value from configuration (env vars, saved settings); user request input never flows into the URL parameter. - New test file `backend-client-retry.test.ts` covers all three paths: GET retries on 503, POST does not retry, timeout does not increment the breaker. * fix(resilient-fetch): address Codex adversarial findings Closes the three blocking issues from Codex's review on PR #1448. U1 — Add `recordNeutral()` to CircuitBreaker. Third outcome path that's an explicit no-op for state and the consecutive-failure counter. Distinct from `recordSuccess` (closes the breaker) and `recordFailure` (may open it). Used for outcomes that are neither evidence of backend health nor evidence of backend failure. U2 — Route terminal-client / terminal-network through `recordNeutral`. Previously a 401 or local timeout called `recordSuccess`, which reset `consecutiveFailures` to 0. A 5xx → 401 → 5xx → 401 → 5xx sequence would NEVER trip the breaker because each 4xx in between erased the running count. Also classify external `AbortError` as terminal-network (was retryable-network), so caller-driven cancellation no longer retries against an already-aborted signal or counts toward breaker failures on exhaustion. U3 — Per-origin breaker key in web `fetchWithTimeout`. Was hardcoded to `'web-backend'` even though `_backendUrl` is mutable via `setBackendUrl`. Switching backend URLs after a circuit tripped on host-A would strand the user during the full cooldown. Key is now `web-backend:<origin>`, so each backend URL gets its own breaker state. Tests: +5 recordNeutral, +4 resilient-fetch (interleaved 4xx/5xx, external AbortError, prior-state preservation), +1 web switch-backend regression. All 70 gitnexus integration tests + 15 web tests green. * fix(resilient-fetch): tolerate header-less fetch mocks on 429 `classifyOutcome` called `resp.headers.get('Retry-After')` directly, which crashed when a test stubs `fetch` with a plain object like `{ ok: false, status: 429 }` (no `headers` field). Real `Response` always has Headers, so this surfaces only in test setups, but the helper has no business assuming caller-side correctness on this — the defensive guard is cheap and a missing `Retry-After` falls through to exponential-backoff retry like any 429 without the header. Surfaced by `gitnexus/test/unit/http-embedder.test.ts > retries on rate limit`, which the embeddings migration exercises against a plain-object 429 stub. Locked in with a new `classifies 429 from a header-less fetch mock without throwing` case. * fix(review): apply autofix feedback Closes findings from the third multi-agent review pass on PR #1448. #1 (P1) callLLM had no per-attempt timeout Wiki LLM calls passed no `signal` to resilientFetch; each of three retry attempts could hang indefinitely on a frozen TCP connection. Add `signal: AbortSignal.timeout(60_000)` so the per-attempt budget matches what http-client.ts and backend-client.ts already provide. #2 (P2) drop dead `lastRetryableResp` post-loop fallback Variable was set in one switch arm but only read in unreachable code after the loop. The retry loop always returns/throws on every iteration. Keep only the defensive `throw` so TypeScript's control-flow analysis still sees `Promise<Response>` as the return. #5 (P2) gate test-only exports behind a subpath `__resetBreakerRegistry__` and `classifyOutcome` were reachable from the main `gitnexus-shared` barrel — production code calling `__resetBreakerRegistry__` from a tool implementation would silently nuke every circuit breaker process-wide. Move to a new `gitnexus-shared/test-helpers` subpath export. Production callers see the cleaner public API; tests import via the explicit `gitnexus-shared/test-helpers` path. #6 (P2) exhaustiveness guard on Outcome switch Add a `default: const _: never = outcome` arm so a future sixth `Outcome.kind` won't compile silently — it'll surface at the switch site rather than fall through to a retry/no-retry default. #9 (P3) document cumulative wall-clock budget Add a "Cumulative wall-clock budget" paragraph to resilientFetch's JSDoc explaining the worst-case total wait (`maxAttempts × (per-attempt timeout + capDelayMs)` ≈ 60s with defaults) and pointing callers at outer `AbortSignal.timeout()` when they want a tighter bound. Deferred to follow-up PRs (per review's Auto-resolve recommendation): - #3 idempotency knob to shared API (forceRetry into ResilientFetchOptions) - #4 publish.ts migration to resilientFetch - #7 parseRetryAfter past-HTTP-date / negative-seconds asymmetry - #8 recordNeutral counter time-decay (documented breaker semantic) * fix(circuit-breaker): gate half-open to a single in-flight probe Closes the Codex adversarial-review finding on PR #1448 that flagged a recovery-time thundering herd: when cooldown expired, every concurrent caller transitioned the breaker to half-open and probed the still- recovering dependency in lockstep, defeating the breaker's "fail fast" promise. U1 — probe-permit gate in CircuitBreaker.check() Added a `probeInFlight: boolean` field. After cooldown expires, the first `check()` admits the probe and consumes the permit; subsequent callers throw `CircuitOpenError` with a configurable `halfOpenRetryAfterMs` (default 1000ms) until the probe resolves. Critical design point: `recordNeutral` now RELEASES the permit but does NOT transition state. Without that split, a single `TimeoutError` from per-attempt `AbortSignal.timeout` (which routes through neutral classification) would permanently park the breaker in half-open. By separating permit-release from state-resolution, we keep the "neutral doesn't claim health" semantic without creating that wedge. Other changes: - `halfOpenRetryAfterMs` is now a constructor option for consumers with long-running protected ops (LLM streaming, large uploads). - `getState()` is documented as a pure read; the implicit Open -> Half-Open transition lives in `check()` only, so tests that inspect state never inadvertently consume a probe permit. - `isProbeInFlight()` test-only accessor for assertion clarity. - JSDoc on `check()` records the JS event-loop atomicity dependency and the load-bearing `try/finally` pairing invariant. U2 — End-to-end concurrency regression through resilientFetch Three new scenarios in resilient-fetch.test.ts (26 -> 29): - 3 concurrent calls + probe gets 200 -> 1 hits fetch, 2 throw CircuitOpenError, breaker closes. - 3 concurrent calls + probe gets 503 -> ResilientFetchExhaustedError on probe; concurrent callers see halfOpenRetryAfterMs (1000ms); fresh caller after probe resolves sees the FULL new cooldown (10000ms), not the probe-in-flight default. - Probe cancelled mid-flight via AbortError -> permit released, state stays half-open, next caller becomes the new probe and succeeds. Plus 9 new circuit-breaker unit tests (16 -> 25) covering the permit gate, recordNeutral-releases-permit semantic, fresh-cooldown distinction, default vs configurable halfOpenRetryAfterMs, getState() purity, and the three-probes-via-neutrals chain. Total integration test count: 70 -> 82. All 106 gitnexus + 15 web tests pass; both packages typecheck. Maintainer decisions (deferred per plan 003 Open Questions): - Plan 002's deferral judgement was reversed on Codex's argument without new measurement / incident data. The reversal is defensible on principle (Hystrix / Resilience4j alignment) but lacks workload- driven evidence. - Probe-blocked callers throw silently (no log / event hook). R4's "no new public API" prevents adding observability; loosen if a debug log on probe-blocked is wanted. * refactor(embeddings): replace bespoke HF breaker with shared CircuitBreaker Deleted the local `HfDownloadCircuitBreaker` class and the manual retry loop in `withHfDownloadRetry`. Both are now backed by the shared `gitnexus-shared` primitives: - `hfDownloadCircuit` is `new CircuitBreaker({ failureThreshold, cooldownMs, key: 'hf-download' })` — same state machine as before PLUS the single-permit half-open gate that prevents recovery-time stampedes when CLI + MCP embedders concurrently re-load the model. - `withHfDownloadRetry` delegates the loop to `withRetry` from the shared package. Per-attempt timeout (`withDownloadTimeout`), network-vs-non-network classification, circuit recording, and the `onRetry` callback wire through `withRetry`'s `isRetryable` callback. Behaviour preserved: - Pre-flight `CIRCUIT_OPEN_TAG` rejection when the breaker is open. - Mid-loop `CIRCUIT_OPEN_TAG` "opened after N consecutive failures" when a network error trips the threshold. - Non-network errors (e.g. CUDA unavailable) bypass retry and go through `recordNeutral` instead of resetting the breaker's failure-count progress. - `onRetry(attempt+1, max, err)` fires only when there's a next attempt, matching the prior semantic. Generic CircuitBreaker gained two inspection accessors: - `getOpenedAt(): number | null` - `getCooldownMs(): number` Used by `withHfDownloadRetry` to compute `secsUntilReset` without consuming a probe permit (which `check()` would do). Test consolidation: the 7 bespoke `HfDownloadCircuitBreaker` state-machine tests in hf-env.test.ts were 1:1 duplicates of existing tests in `circuit-breaker.test.ts` and were deleted. Remaining 42 hf-env tests all pass; full integration sweep (148 gitnexus + 15 web) green.

ce-code-review surfaced 15 findings on PR #1458; this commit applies the 7 with concrete fixes (#1, #2, #3, #4, #5, #9, #13). Five P2 findings (#6, #7, #8, #10, #12) are recorded as residual actionable work for follow-up; two advisory items (#11, #14) skipped. #1 — applied_run_id schema drift (CONTRIBUTING.md): v2 docs claimed `state: applied` enum value and an `applied_run_id` field that no code path emits. Trimmed docs to match what the workflow actually writes (state: fixes-available; v1 field set as superset). Implementing the apply-side sticky upsert that would populate `applied_run_id` is deferred — cleaner than carrying a contract claim with no code. #2 — result= unset between idempotency probe and lease push (pr-autofix-apply.yml): After `git apply --check` passed, an early non-zero exit from `git config` / `git apply` / `git add` / `git commit` left `result=` unset, sending the user to the `*` "unexpected state (`unknown`)" arm. Wrapped the apply/commit phase in a single if-test that sets `result=apply-failed` on any failure. New React-and-reply branch surfaces an actionable message. #3 — permission lookup conflated transient API failures with denial (pr-autofix-apply.yml): `gh api … 2>/dev/null || echo "none"` swallowed 5xx, 429 secondary rate-limit, and network failures, surfacing them as a public 👎 refusal to legitimate maintainers. Now distinguishes 404 (genuine non-collaborator) from other API failures via stderr match. New `allowed=api-failed` state triggers a 😕 reaction with a "transient API failure, retry" reply instead of a misleading refusal. #4 — lease-failure grep missed git's "remote rejected" / branch- deleted phrasings (pr-autofix-apply.yml): Real lease failures got classified as `push-failed` → user told to enable maintainer-edit, which won't help. Expanded regex to match `remote rejected` and `! [rejected]`. #5 — broken bullet continuation in CONTRIBUTING.md release-candidate section: rejoined the split bullet so it renders correctly. #9 — base64 GITHUB_TOKEN bypassed GitHub's secret-masker (pr-autofix-apply.yml): Added `::add-mask::${auth_header}` immediately after construction so any subsequent log line (set -x, GIT_TRACE) gets *** redacted. #13 — misleading schema-bump comment in pr-autofix-publish.yml: Comment claimed all v1 fields preserved exactly, but the `state` enum was redefined v1→v2. Updated to make the migration path explicit (v1 readers see unfamiliar schema, fall back to prose). Residual actionable work (deferred to follow-up): #6 locate step gh api retry; #7 artifact-expired graceful fallback; #8 re-entrancy comment-spam guard; #10 producer-still-running UX; #12 gh_retry wrapper for apply.yml. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK.

…1458) * fix(autofix): verify reviewdog actually posted before claiming "click Apply" The sticky summary comment was stating "Posted formatting suggestions inline. Click Apply suggestion on each" even when reviewdog landed zero inline review comments — typical case: the formatter touched lines outside the PR's added range, so `-filter-mode=added` (correctly) filtered everything out. The script unconditionally set `posted=true` after running reviewdog regardless of whether any comments were actually created, leaving the user staring at a sticky that promised buttons that didn't exist. The publish job now snapshots the count of `github-actions[bot]` review comments before and after reviewdog. If the delta is zero, surface a new `diff-no-overlap` UI state that tells the user plainly: "Formatter found fixable issues, but they're on lines outside this PR's added range — there's nothing to click here. Run locally: npm run lint:fix && npm run format." Plus a matching `gitnexus/autofix` Check Run conclusion (still neutral, distinct title) so agents reading `gh pr checks` see the same signal. Three states are now machine-distinguishable in the sticky's gitnexus-autofix JSON block: suggestions-posted (delta > 0), diff-no-overlap (delta == 0), skipped-too-large (>3k lines). * feat(autofix): replace inline reviewdog with /autofix ChatOps button Pivot the PR autofix UX from per-line reviewdog suggestions to a single slash-command button. Contributors comment `/autofix` on the PR; a new trusted workflow downloads the existing autofix patch artifact, applies it to the PR head, and pushes a commit back. Why: - 3K+ diffs hit GitHub's review-comment API 406 limit -> dead end. - Diffs where the formatter touches lines outside the PR's added range ("no-overlap") get filtered by reviewdog's -filter-mode=added -> dead end (PR #1457 patched the lying sticky but the underlying UX gap remained). - Per-line click-Apply-suggestion is high-friction for big diffs and easy to apply unevenly. - A single `git apply` + push works at any size and lands fixes atomically. Changes: - pr-autofix-publish.yml: remove `Install reviewdog` and `Post inline suggestions` steps. Collapse three sticky states (suggestions-posted, diff-no-overlap, skipped-too-large) into one (fixes-available). Bump JSON schema v1 -> v2 with `apply_command` field; all v1 fields preserved. - pr-autofix-apply.yml (new): triggers on issue_comment with body `/autofix`, validates body via strict regex, validates commenter has write/admin/maintain or is the PR author, locates latest successful pr-autofix run for PR head SHA, downloads artifact, applies patch, pushes commit. Reacts +1/-1/eyes on triggering comment per outcome. Idempotent (`git apply --check --reverse` detects already-applied state). - CONTRIBUTING.md: document v2 schema and the /autofix flow, including the maintainer-edit requirement for fork PR pushes. Trust posture: apply workflow runs from default-branch code only, under issue_comment trigger. Comment body and author login flow through env vars and pattern-matched, never interpolated into shell. Permission gate (write/admin/maintain OR PR author) before any artifact fetch. Fork PRs require "Allow edits by maintainers" (GitHub-native; we don't bypass). Net YAML: -139 lines in publish.yml, +260 in apply.yml. Removes reviewdog binary pin and the entire review-comment API surface. * fix(autofix): address Codex adversarial findings on PR #1458 Two findings from the Codex adversarial review of the autofix ChatOps pivot. Both are localized YAML changes that close trust gaps the pivot inherited from the original PR #1446 design. U1 — Cross-verify metadata against workflow_run authority (.github/workflows/pr-autofix-publish.yml): Previously the trusted publisher accepted pr_number, head_sha, and head_repo from metadata.json after only an allowlist regex. A fork-controlled `npm run lint:fix` could have written a syntactically valid metadata.json referencing another PR/SHA, redirecting the write-scoped sticky/check-run onto an attacker-chosen target. New `Verify metadata against workflow_run authority` step compares artifact-claimed identity against: - github.event.workflow_run.head_sha - github.event.workflow_run.head_repository.full_name - workflow_run.pull_requests[].number (within-repo PRs) - gh api commits/{sha}/pulls fallback (fork PRs, where pull_requests[] is empty) Fail closed on mismatch — no sticky, no check-run, no override. U2 — Lease-protected push in apply workflow (.github/workflows/pr-autofix-apply.yml): Previously the apply step pushed `HEAD:${HEAD_REF}` plain. A force- push between resolve (Step 5) and push (Step 9) would silently fast-forward an older commit graph over the contributor's newer state. Push now uses `--force-with-lease=refs/heads/${HEAD_REF}:${HEAD_SHA}` against the SHA resolved earlier. Distinct `lease-failed` result code + retry-message reply, separated from `push-failed` (fork without maintainer-edit) so contributors can diagnose the actual cause. Plan: docs/plans/2026-05-09-005-fix-autofix-codex-adversarial-findings-plan.md (local-only per repo convention). Trust posture preserved: no new permissions, no new workflows, no contract change. JSON v2 schema unchanged. CodeQL js/server-side- request-forgery and template-injection posture unchanged — all new inputs flow via env vars and pattern-matched. * fix(autofix): close zizmor credential-persistence finding on apply checkout actions/checkout's default behavior writes the GITHUB_TOKEN into .git/config as an extraheader. The token then sits on disk in the checkout directory — an actions/upload-artifact step on that directory would leak it. We don't upload, but zizmor's credential-persistence lint correctly flags the latent risk. Set persist-credentials: false on the Checkout PR head step. Provide push auth inline via `git -c http.extraheader="Authorization: Basic <base64-of-x-access-token:TOKEN>"` so the credential never lands on disk and never appears in process listings (the URL form https://x-access-token:TOKEN@… is rejected here because it leaks via ps and git remote -v). Push lease semantics from U2 unchanged — same --force-with-lease against the resolved HEAD_SHA, same lease-failed/push-failed/stale result codes. * fix(review): apply autofix feedback ce-code-review surfaced 15 findings on PR #1458; this commit applies the 7 with concrete fixes (#1, #2, #3, #4, #5, #9, #13). Five P2 findings (#6, #7, #8, #10, #12) are recorded as residual actionable work for follow-up; two advisory items (#11, #14) skipped. #1 — applied_run_id schema drift (CONTRIBUTING.md): v2 docs claimed `state: applied` enum value and an `applied_run_id` field that no code path emits. Trimmed docs to match what the workflow actually writes (state: fixes-available; v1 field set as superset). Implementing the apply-side sticky upsert that would populate `applied_run_id` is deferred — cleaner than carrying a contract claim with no code. #2 — result= unset between idempotency probe and lease push (pr-autofix-apply.yml): After `git apply --check` passed, an early non-zero exit from `git config` / `git apply` / `git add` / `git commit` left `result=` unset, sending the user to the `*` "unexpected state (`unknown`)" arm. Wrapped the apply/commit phase in a single if-test that sets `result=apply-failed` on any failure. New React-and-reply branch surfaces an actionable message. #3 — permission lookup conflated transient API failures with denial (pr-autofix-apply.yml): `gh api … 2>/dev/null || echo "none"` swallowed 5xx, 429 secondary rate-limit, and network failures, surfacing them as a public 👎 refusal to legitimate maintainers. Now distinguishes 404 (genuine non-collaborator) from other API failures via stderr match. New `allowed=api-failed` state triggers a 😕 reaction with a "transient API failure, retry" reply instead of a misleading refusal. #4 — lease-failure grep missed git's "remote rejected" / branch- deleted phrasings (pr-autofix-apply.yml): Real lease failures got classified as `push-failed` → user told to enable maintainer-edit, which won't help. Expanded regex to match `remote rejected` and `! [rejected]`. #5 — broken bullet continuation in CONTRIBUTING.md release-candidate section: rejoined the split bullet so it renders correctly. #9 — base64 GITHUB_TOKEN bypassed GitHub's secret-masker (pr-autofix-apply.yml): Added `::add-mask::${auth_header}` immediately after construction so any subsequent log line (set -x, GIT_TRACE) gets *** redacted. #13 — misleading schema-bump comment in pr-autofix-publish.yml: Comment claimed all v1 fields preserved exactly, but the `state` enum was redefined v1→v2. Updated to make the migration path explicit (v1 readers see unfamiliar schema, fall back to prose). Residual actionable work (deferred to follow-up): #6 locate step gh api retry; #7 artifact-expired graceful fallback; #8 re-entrancy comment-spam guard; #10 producer-still-running UX; #12 gh_retry wrapper for apply.yml. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK. * fix(autofix): apply remaining ce-code-review residual findings (#6, #7, #8, #10, #12) Pulls the deferred items from the previous review pass into this PR so the workflow ships with full reliability + UX coverage rather than follow-up debt. #6 + #12 — gh_retry wrapper on idempotent GETs in apply.yml: Permission lookup, PR metadata fetch, and workflow-run lookup are now wrapped in the same gh_retry helper publish.yml uses (3 attempts, linear backoff). Reaction/comment POSTs remain unwrapped (retrying POST would dupe the resource). #10 — producer-still-running UX: The locate step now distinguishes three cases via `found_status` output: success (proceed), in-progress / queued / pending / waiting (reply ⏳ "wait for autofix run to finish"), not-found (reply 🤔 "push a commit"), api-failed (reply ⚠️ "transient API failure"). The "no successful autofix run" message no longer fires immediately after a fresh push while the producer is still mid-run. #7 — artifact-expired graceful fallback: actions/download-artifact gains `continue-on-error: true`. The apply step distinguishes patch-file-missing (artifact expired, 1-day retention elapsed) from patch-file-zero-bytes (formatter found nothing). New `result=artifact-expired` case + ⏳ "push a new commit to regenerate" reply. #8 — re-entrancy loop guard: After checkout but before applying, check if HEAD itself is a github-actions[bot] `chore(autofix)` commit. If so, refuse to re-apply (`result=loop-prevented`) with a 🔁 reply telling the user to push a human-authored commit or revert before retrying. Prevents formatter-config-drift loops where an automated agent watching the sticky could pump arbitrary apply commits. Net effect: every code path in apply.yml now sets a meaningful `result=` that maps to a specific user-facing reaction + reply. The `*` "unexpected state (unknown)" arm becomes truly unreachable in normal operation. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK. * fix(autofix): refresh stale reviewdog comments + reject patches touching .github/ Two follow-up findings on PR #1458: #1 — Stale reviewdog references in workflow header comments: pr-autofix-publish.yml's header still described the removed inline- suggestion path ("posts inline review-comment suggestions to the PR using `reviewdog`", "Reviewdog reporter: github-pr-review reads $REVIEWDOG_GITHUB_API_TOKEN…"). The Check Run permissions comment enumerated the old outcomes (clean / suggestions-posted / skipped-too-large) instead of the current set (clean / fixes- available). pr-autofix.yml's header described the trusted job as posting "inline review-comment suggestions" and the changed_lines comment referenced the dead 3000-line cap. Refreshed all three to describe the actual sticky + Check Run + /autofix flow. #2 — Reject patches touching .github/ (sensitive-paths guard): Theoretical supply-chain vector: a malicious PR could ship a custom prettier/ESLint config that reformats workflow YAML, dependabot.yml, or CODEOWNERS. The producer would capture those edits in autofix.patch; a maintainer running `/autofix` would push them under `contents: write` without human review. The default GITHUB_TOKEN lacks the `workflows` scope so workflow-file pushes would fail at the platform layer anyway, but as a generic `push-failed` (which misleads users into enabling maintainer-edit). Reject early with a specific reason. Match runs against the patch with grep on `^(diff --git|---|+++) [ab]?/?\.github/`. New `result=sensitive-paths` case + 🛑 reply telling the user to apply .github/ formatter changes manually. Documented the constraint in CONTRIBUTING.md under the /autofix section so contributors aren't surprised when the workflow refuses a patch that includes formatter changes to workflow files. Validations: yaml.safe_load OK, check-workflow-concurrency.py OK.

Walks the full set of findings from a multi-agent code review (11 reviewers, 1 maintainability dispatch lost to tool-permission denial) of the PR #1693 branch. All 16 actionable findings — 4 P1, 4 P2, 8 P3 — applied in a single pass against a consistent tree. Tests pass (269/269 unit files, 29/29 integration). P1 — bounds-only / disguised-bounds assertions across 4 test files (per user-memory DoD §2.7): - worker-pool.test.ts: 5 sites — `nodes.length > 0` dropped (redundant after `.toContain('validateInput')`); `files.length >= 4` pinned to `.toBe(7)` (mini-repo/src has exactly 7 .ts files); `results.length > 0` pinned to `.toHaveLength(1)` (default sub-batch absorbs all 7); `result.fileCount >= 0` pinned to `.toBe(1)` (empty file is still "processed"); `warnRecords.length > 0` replaced with content- predicate `/respawn|dropping|replacement|did not report ready/` (catches silenced warnings); `fallbackExcludePaths.length > 0` pinned to exact `['one.ts', 'two.ts']` (deterministic given the single-slot pool + 2 items + per-item starting-file). - parse-impl-fallback.test.ts: 3 sites — `astCacheClearCalls >= 1` pinned to exact 4 (per-chunk × 2 + finally × 2); the two error-path delta checks pinned to exact +2 and +3 (verified empirically). - parse-impl-progress-monotonic.test.ts: `percents.length > 0` → `.not.toEqual([])`; per-element `Math.max(prev, cur)` tautology replaced with direct `if (cur < prev) throw`; final-percent `Math.min(last, 95)` tautology pinned to exact `.toBe(70)` (3-file skipWorkers fixture's deferred band lands at the band start). - parse-impl-large-fixture.test.ts: `Math.min(elapsedMs, BUDGET)` tautology removed; Promise.race rejection is the load-bearing wall-clock check. P1 — terminate() lacks `.catch` mask: - worker-pool.ts terminate() now matches the `.catch(() => undefined)` pattern used at every other internal terminate site. Prevents a hung/OOM worker's terminate rejection from masking the original pipeline error when called from parse-impl.ts's finally block, and guarantees `workers.length = 0` / `activeSlots.clear()` always run. P1 — hybrid envelope length-mismatch + null-payload silent data loss: - parse-worker.ts decodeIncomingMessage: explicit non-null-and-typed check before `.type` access (decodeMessage permits null payloads per encodeMessage contract); explicit length-equality assertion between `decoded.files` and `contents` before zipping. Without these, `TextDecoder.decode(undefined)` silently returns "" and produces empty-content graph nodes — a contract violation that used to be undetectable. Both throws route through the outer try/catch → worker `error` reply → pool's recoverAndResume. P1 — unsafe casts at the IPC boundary: - buildDispatchMessage now uses a properly-typed `isParseWorkerItemArray` type guard. The narrowed branch accesses `item.path` and `item.content` as statically-typed strings — a future rename of `ParseWorkerInput.content` would fail to compile inside the branch instead of silently mismatching at runtime. The remaining decodeMessage payload casts are bounded by the F3/F6 runtime guards. P2 — idle-timeout retry bypasses circuit breaker: - worker-pool.ts timeout-retry IIFE now increments `consecutiveFailuresPerSlot[workerIndex]` alongside `respawnCount`. A slot that consistently times out (vs crashes) now trips the per-slot breaker, instead of consuming its full respawn budget over potentially tens of minutes without the breaker firing. P2 — null/non-object worker message crashes pool handler: - Dispatch handler in worker-pool.ts now guards `null / non-object / no string type discriminant` before `msg.type` access and routes through recoverAndResume on violation. Previously a legitimate `null` payload would throw TypeError out of the EventEmitter listener → uncaughtException on main, crashing the analyze. P2 — workerPoolSize === 0 creates unusable pool: - parse-impl.ts now treats `workerPoolSize === 0` as `skipWorkers` at the gate. Matches the PipelineOptions docstring contract ("0 disables the pool entirely — equivalent to skipWorkers"); avoids constructing a pool that rejects every dispatch and logs "Worker pool parsing stopped" per chunk. P2 — encodeMessage 2-buffer allocation per frame: - protocol.ts encodeMessage coalesced to a single `Buffer.allocUnsafe + writeUInt8 + writeUInt32LE + buf.write (string, offset, 'utf8')`. Drops the intermediate `Buffer.from(JSON.stringify(...), 'utf8')` allocation + memcpy. Length pre-check via `Buffer.byteLength(string, 'utf8')` surfaces the uint32 cap before any allocation. P3 — slotGenerations made optional on WorkerPoolStats so external implementations of getStats() that predate U12 don't compile-break; in-repo callers already use optional chaining. P3 — buildDispatchMessage marked `@internal` so it isn't surfaced as public API by typedoc / api-extractor (it's a test-only export). P3 — verboseThroughputLog hoisted above the chunk loop (env vars can't change mid-run; one O(env-read) per analyze, not per chunk). P3 — corrected the messageerror routing comment in worker-pool.ts dispatch handler. `ProtocolDecodeError` is caught by the surrounding try/catch — distinct from `messageerror`, which fires for V8 structured-clone failures before the message body would reach the handler. P3 — initial pool spawn now uses a `Promise.allSettled` ready-handshake gate symmetric with `replaceWorker`. Dispatch awaits this gate before selecting slots, so an init-crashing initial worker is dropped from `activeSlots` and a downstream OOM/missing-native-binding failure surfaces in seconds (bounded by WORKER_READY_TIMEOUT_MS) rather than waiting for the first idle timeout (30s default). P3 — `GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT`, `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS`, `GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD` added to: - CLI `--help` text in src/cli/index.ts - Root README env-var table - gitnexus/README troubleshooting section (new "Worker pool resilience tuning" subsection) P3 — CLI `catch (e: any)` / `catch (err: any)` in analyze.ts replaced with `catch (err: unknown)` + narrowed access; matches modern TS best practice and the codebase pattern at other catch sites. P3 — `WorkerPoolStats.terminated: boolean` field added (optional, for backward compatibility). `terminate()` sets it true; `getStats()` surfaces it. Distinguishes graceful shutdown from a circuit-breaker trip in observability surfaces. Coverage / advisory items not addressed in this commit (kept in the report only): - maintainability reviewer failed (Read/Bash denied) — god-module audit on worker-pool.ts (~1400 LOC) carried as residual risk - quarantine case-sensitivity contract unpinned (adversarial #8) - WORKER_READY_TIMEOUT_MS env-configurability (adversarial #2) - chunk-byte-budget × parseChunkConcurrency memory multiplier doc (adversarial #5) - MCP discoverability gaps for env vars / verbose (agent-native W1/W2) - bench/parse-throughput.md scaffold-with-TBD-rows (PS RR-003)

…nalyze hangs on TS-root-scale loads (#1693) * Initial plan * fix: skip worker-timeout files in sequential fallback and optimize TS capture node lookup Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/0e53743e-0600-4690-bd0d-198894daef58 * refactor: clarify TS capture helpers after validation feedback Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/0e53743e-0600-4690-bd0d-198894daef58 * fix(workers): exclude in-flight file on worker error/exit, not just singleton timeout WorkerPoolDispatchError previously surfaced the stalled path only for the singleton-timeout final-fail branch. Worker `error` and `exit` events (and the msg-channel `error` reply) fell back to plain `Error`, so the sequential fallback re-attempted every file in the active job — re-hanging on the same pathological file when the worker crashed mid-parse. Lift the in-flight-file inference into `inFlightExcludePath(job, lastProgress)` and wire it into the three remaining in-pool failure sites. `lastProgress` is already in `runWorker` scope, so `items[lastProgress]` (the next file the worker was about to acknowledge) is the best single guess at the culprit; earlier files are still re-tried sequentially. Returns `[]` when no path is determinable (`lastProgress >= items.length`, or path missing/non-string) so sequential retries the whole job. Replacement-worker startup failures stay plain `Error` (no job context); the result-before-flush protocol bug stays plain `Error` (code fault, not file). Tests cover the three new exclusion paths plus a negative test confirming non-WorkerPoolDispatchError throws fall through to full sequential retry. * fix(review): apply autofix feedback - Use cause-neutral "worker-excluded" label in skip messages and tests now that worker error/exit paths share the same exclusion contract as singleton-timeout (correctness + maintainability reviewers). - Add JSDoc to findSelfOrAncestorOfType{s} explaining the parent-walk short-circuit vs root-DFS fallback (maintainability reviewer). * feat(workers): resilient + scalable worker pool Restructures `createWorkerPool` so a single bad file no longer kills the pool for the rest of an analyze run. Five interlocking layers: 1. **Auto-respawn on error/exit** — worker death triggers `replaceWorker` on the same slot, bounded by `maxRespawnsPerSlot` (default 3). The slot is dropped from rotation when the budget is exhausted; other slots keep running. 2. **Circuit breaker** — replaces the permanent `poolBroken=true` with a consecutive-failure counter. The pool only trips after `consecutiveFailureThreshold` deaths (default `max(3, poolSize)`) with no successful job in between. A successful job resets the counter so transient bursts of bad files don't escalate. 3. **Session-scoped file quarantine** — paths identified as the in-flight file at the moment of a worker death are added to a `Set<string>` on the pool. `dispatch()` filters quarantined items up front (they never reach a worker again this pool lifetime). Exposed via the new `WorkerPool.getQuarantinedPaths()` so callers can log/route them. `processParsing` surfaces the per-chunk quarantine summary alongside the existing fallback-exclusion log. 4. **Authoritative in-flight tracking** — `parse-worker.ts` emits `{type:'starting-file', path}` before each file. The pool tracks this per slot and uses it for crash attribution, falling back to the `items[lastProgress]` heuristic only when no starting-file has been observed (very-early crash, older worker build). Closes the reorder/race concerns raised by reviewers C1 and R3 in the earlier review run. 5. **Per-job cumulative timeout budget** — each `WorkerJob` tracks the total wall time spent across attempts/splits/retries. When the budget is exhausted (default 5x `subBatchIdleTimeoutMs`), the pool surfaces the in-flight path instead of letting exponential backoff balloon into multi-hour stalls. Cross-layer wiring: a new `wakeIdleSlots` helper kicks any non-busy live slot when items are requeued (after a death or split-retry), so a dropped slot doesn't strand work in the queue. `recoverAndResume` consolidates the per-job teardown shared by the three in-pool death sites (`error`, `exit`, msg-channel `error`). New env knobs: `GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT`, `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS`, `GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD`. New `WorkerPoolOptions.workerFactory` injection point for unit tests. Tests: 12 new unit tests using a FakeWorker mock cover quarantine seeding, slot-respawn, slot-drop after budget, breaker trip + reset, and quarantine filtering. Plus option-resolution tests for the three new env vars. All 19 worker-pool/-fallback/-options tests pass; full unit suite 6040 passed / 30 skipped / 0 failed. * fix(workers): apply code-review fixes (12 findings) Walks through every finding from ce-code-review run 20260519-094648-3549cf5e. All 12 picked Apply. Critical: - F1 — Layer 5 cumulative-timeout exhaustion no longer silently drops the rest of the job. `requeueRemainder` is now invoked before `handleWorkerDeath` in both Layer 5 and singleton-final-fail give-up paths so non-quarantined items get re-tried by another worker. - F2 — idle-timer recovery overhaul. `!shouldContinue` branch no longer calls `replaceWorker` (double-spawn race with the `handleWorkerDeath` inside `requeueAfterTimeout`). `shouldContinue` branch now enforces `maxRespawnsPerSlot` before respawning, closing the budget-bypass for the timeout-retry path. Also fixes premature `maybeDone` by simplifying the bookkeeping. - F3 — `requeueRemainder` no longer pre-charges `cumulativeTimeoutMs` by `job.timeoutMs`. The death itself consumed no budget, so the next `requeueAfterTimeout` was double-billing the first attempt. - F4 — `WorkerPool.getQuarantinedPaths` is now optional on the interface, matching the defensive `?.()` call site and the existing mocks. Removes the contract-vs-callsite contradiction. - F5 — per-job unattributed-death tracking. When a worker dies with no exclusion attribution, `requeueRemainder` tracks death count per `startIndex`. First time: re-queue intact. Second time: quarantine items[0] as best guess, or drop the job entirely when items lack paths. Bounds the death loop the original design admitted to. - F6 — per-slot consecutive-failure counter. Replaces the pool-wide scalar so a chronically-failing slot trips the breaker on its own streak instead of being masked by another slot's successes. Smaller: - F7 — exhaustiveness `never` check on `WorkerOutgoingMessage` union. - F8 — recursive `runWorker` on fully-quarantined jobs converted to a while-loop. - F9 — `tripBreaker` calls `reject(err)` BEFORE awaiting `worker.terminate()`. A stuck terminate no longer blocks the caller. - F10 — `parsing-processor.ts` quarantine log de-duplicates per pool instance via a `WeakMap`. Only newly-quarantined paths are logged in each chunk; the per-chunk count still surfaces via progress. - F11 — extract `firstPath` local in `requeueAfterTimeout`; eliminates double `itemPath` call and the `unknown as string` cast. Tests (F12, 6 new): - crash-error event path (errorHandler). - F5 drop-branch coverage via items without `.path`. - Common-case unattributable crash falling back to items[0] heuristic. - `replaceWorker` startup failure (workerFactory emits 'exit' before 'online'). - All-slots-dropped breaker trip. - `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS` env override. Residual gap (deferred): no unit test exercises the Layer 5 cumulative-budget runtime path — requires fake-timer interleaving with FakeWorker that's too brittle for this iteration. Tracked. Unit suite: 257 files / 6056 passed / 30 skipped / 0 failed. * test(workers): integration tests for resilience layers + fix requeue-after-timeout flow Adds 6 new real-worker integration tests covering the PR #1693 resilience layers + fixes 3 follow-on bugs surfaced while writing them. New integration coverage (real worker threads + temp fixture scripts): - `respawns the slot after worker process.exit and finishes the work on the replacement` — exercises Layer 1 auto-respawn + Layer 3 quarantine through real IPC. - `attributes exactly via authoritative starting-file message on worker crash` — Layer 4 end-to-end: starting-file message → exact quarantine attribution (not the items[0] heuristic). - `quarantine filters subsequent dispatches without sending to a worker` — second dispatch's sub-batch payload audited via filesystem; the quarantined path is never sent across the message channel. - `drops a slot after maxRespawnsPerSlot and continues on the survivor` — 2-slot pool, slot dies twice past budget, survivor finishes re-queued remainder. - `trips the circuit breaker on cascading per-slot consecutive failures` — single-slot pool, dies on every job, breaker trips after consecutiveFailureThreshold with WorkerPoolDispatchError carrying the cumulative quarantine. - `survives a worker error event (uncaught throw) the same as a process.exit` — validates recoverAndResume on the errorHandler path via a real worker `throw` (not just process.exit). Bug fixes uncovered while writing these tests: 1. **Stack-overflow recursion in runWorker's no-worker branch** — `if (!worker) { ...; wakeIdleSlots(); maybeDone(); }` recursed indefinitely when multiple slots were mid-respawn simultaneously (wakeIdleSlots → runWorker → no worker → wakeIdleSlots → …). Removed the wakeIdleSlots call: the slot's own respawn IIFE owns runWorker post-respawn, and other slots will pick up work via finishJob's runWorker. 2. **requeueAfterTimeout dispatched work before respawn completed** — the F2 fix had `requeueAfterTimeout` `void`-discarding `handleWorkerDeath`, so the `!shouldContinue` IIFE had no way to know when the respawn finished. New design: `requeueAfterTimeout` returns a `TimeoutDecision` discriminated union; the IIFE owns the death-and-respawn-and-dispatch orchestration in an async closure so it can `await handleWorkerDeath` and then call `runWorker` deterministically. 3. **Stalled-singleton + protocol-error + replacement-startup-crash tests** had stale contracts predating the resilience refactor. The stalled-singleton no longer rejects (it quarantines + resolves `[]`); the protocol-error rejection message now mentions "circuit breaker tripped"; the replacement-startup-crash test documents the known `waitForWorkerOnline` race (online fires before the worker's main script runs, so a top-level throw looks like a successful spawn) — the test asserts the file is quarantined via the second-idle-timeout give-up path. Full suite: 334 files / 8982 passed / 43 skipped / 0 failed (second run; first run had a Vitest-reported flake from an uncaught worker exception bleeding into the test report — repeated runs are clean). * perf(workers): raise pool cap to cores-1 + defer per-chunk extraction to keep workers busy User reported 4-5% CPU utilization on a multi-core machine during ingestion. Two structural reasons: 1. **Pool cap.** `createWorkerPool` resolved size as `Math.min(8, max(1, os.cpus().length - 1))` — a 16-core box got 8 workers (50% theoretical max). U1 lifts the default to `min(16, max(1, cores - 1))`, exposes `GITNEXUS_WORKER_POOL_SIZE` env override, and adds `--workers <N>` CLI flag (`0` disables the pool for sequential fallback). 2. **Per-chunk extraction serialized the loop.** Per chunk: dispatch → await workers → main-thread `processImportsFromExtracted` + `processHeritageFromExtracted` + `processRoutesFromExtracted` + `synthesizeWildcardImportBindings` + `seedCrossFileReceiverTypes` → next chunk dispatch. Workers sat idle through every extraction block. U2 (revised from the plan's pipelined-chunks design) defers these passes to a single end-of-loop batch. Chunk loop becomes parse + merge + accumulate. Resolution sees strictly-more-info (full repo graph) so cross-chunk import/heritage targets resolve at least as well as before. Memory cost: `deferredWorkerImports` accumulates across chunks; bounded by total file count, acceptable. Plan deviation note: the plan called for an in-flight chunk pipeline (N concurrent dispatches with bounded memory). That design needed either a `processParsing` API refactor or duplicating its catch-block fallback in `parse-impl`. The deferred-extraction approach delivers the same "workers stay busy" outcome with much smaller surface area and zero changes to `processParsing`. The `GITNEXUS_PARSE_CHUNK_CONCURRENCY` env var documented in U2 of the plan is therefore not implemented in this commit; if memory growth from `deferredWorkerImports` becomes a problem at very-large-repo scale, a bounded sliding-window variant can land as a follow-up. Tests: - New `test/unit/analyze-worker-pool-size.test.ts` covers --workers validation (5 invalid inputs rejected with exit code 1 + clear error; valid integers set the env var; `--workers 0` routes to sequential). - Extended `worker-pool-resilience.test.ts` with `resolveAutoPoolSize` scenarios: env override, env=0, env above cap, invalid env fallback, auto-formula match, integer return type. - Full unit suite: 6097 / 6127 passed / 30 skipped / 0 failed. - Full integration suite (second run): 77 / 78 passed / 1 skipped / 0 failed. First run had a known cosmetic flake from an uncaught worker exception bleeding into the test reporter. Resilience contract from PR #1693 preserved: per-slot respawn budget, circuit breaker, quarantine, authoritative in-flight tracking, cumulative timeout budget — all unchanged. New env vars surfaced in --help: GITNEXUS_WORKER_POOL_SIZE, GITNEXUS_PARSE_CHUNK_CONCURRENCY (reserved for future bounded pipelining). * docs(readme): document --workers CLI flag * feat(workers): add getStats() and per-chunk throughput logging * test(workers): cleanup leaked temp-dirs and drop duplicate option-resolution block - Add afterEach to worker-pool-resilience.test.ts cleaning up the per-test temp directory created by beforeEach (~25 stale dirs per CI run previously). - Delete the duplicated describe('worker pool option resolution', ...) block. Verified the first block (lines 490-532) is a strict superset (includes the GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS env test the second block omitted), so deletion loses no test coverage. Addresses PR #1693 review findings L2 (temp-dir leak) and L3 (duplicate block). * feat(cli): thread --workers via PipelineOptions + snapshot/restore CLI env Resolves PR #1693 review B2 (env-var leak in long-running hosts): - --workers is now threaded through AnalyzeOptions -> runFullAnalysis -> PipelineOptions.workerPoolSize -> createWorkerPool's explicit poolSize arg, bypassing the GITNEXUS_WORKER_POOL_SIZE env channel. The env var remains as a back-compat fallback inside resolveAutoPoolSize for operators who set it directly. - analyzeCommand and wikiCommand snapshot the GITNEXUS_* env vars they mutate at function entry and restore them in finally. Inner *Impl extraction keeps the diff surgical (no body re-indent). process.exit(0) on the CLI success path still terminates the process; restoration matters for programmatic callers (tests, long-running hosts) reaching early-return paths or the alreadyUpToDate fast path. - Tests updated to assert the new behavior: analyze-worker-pool-size.test.ts: workerPoolSize flows through runFullAnalysis options; env is not mutated; back-to-back calls see their own values, not the previous call's leak. analyze-worker-timeout.test.ts: env IS set during the runFullAnalysis call (captured via mockImplementation) and restored after, proving the timeout reaches downstream while the leak fix holds. - Also addresses L4: afterEach NODE_OPTIONS restore so back-to-back test runs don't accumulate --max-old-space-size=8192 tokens. Addresses PR #1693 review B2 (blocker) and L4 (test polish). * feat(workers): harden worker lifecycle (messageerror + availableParallelism + ready handshake) Resolves PR #1693 review H1, H2, M4: H1 - messageerror handler at every dispatch site V8 deserialization failure on postMessage previously left the message silently lost; the pool would wait out the idle timeout (default 30s) instead of treating it as worker death. The dispatch loop now wires worker.once('messageerror', ...) alongside error/exit and routes through recoverAndResume so the existing per-slot respawn budget, in-flight file attribution, and circuit-breaker layers fire as designed. H2 - resolveAutoPoolSize uses os.availableParallelism() Mirrors the pattern at capabilities.ts:85 (defaultEmbeddingThreads). os.cpus().length returns the host CPU count, which over-sizes the pool on cgroup-limited containers, taskset-restricted runtimes, and CI runners with explicit CPU quotas. Falls back to os.cpus().length on Node < 18.14. M4 - worker-side ready handshake replaces online-trust parse-worker.ts now emits {type: 'ready'} after all top-of-script initialization completes, BEFORE the message handler is attached. The pool's renamed waitForWorkerReady listens for this message under a bounded WORKER_READY_TIMEOUT_MS (5s) budget instead of trusting Node's online event - which fires when the worker thread starts, BEFORE the script body runs, letting init crashes slip past pool startup. ready is added to WorkerOutgoingMessage with an exhaustiveness-checked no-op branch in the dispatch handler (defensive: the message is consumed by waitForWorkerReady before dispatch handlers attach). messageerror is wired into waitForWorkerReady the same way. Test scaffolding: - FakeWorker emits {type: 'ready'} in addition to 'online' so replacement workers in unit tests don't hit the 5s budget. - Integration test ad-hoc worker scripts go through a writeReadyWorker helper that prepends the ready handshake. Tests intending to script "crash BEFORE ready" can bypass the helper. 61/61 worker-pool unit tests pass; 28/28 integration tests pass. * feat(parse-impl): monotonic progress + verbose-gated throughput log + seed-before-build Resolves PR #1693 review M2, M3, L1, L5 in a single parse-impl.ts pass: M2 - Monotonic progress through deferred phase (no more "stuck at 82%") Previously the deferred resolution stages (imports, heritage, routes, calls) all emitted percent: 82 — the UI looked frozen for the duration of the deferred work, which on large repos is several seconds to minutes and visually identical to the hang PR #1693 set out to fix. Redistributed: parse phase: 20-70 (was 20-82) imports: 70-75 heritage: 75-80 routes: 80-85 calls: 85-95 Each deferred stage now advances through its own band via the existing per-batch progress callback. Skipped stages (zero deferred input) leave their band as a no-op jump - the next stage still starts at its own band, preserving strict monotonicity. The "no parseable files" early return now jumps to 95 (was 82), and the duplicate "Parsing N files..." announcement is suppressed when totalParseable === 0 to avoid a non-monotonic 95 -> 20 regression that pre-existed (uncovered by the new monotonic test). M3 - Throughput log gated on `--verbose`, not just NODE_ENV=development The per-chunk files/s log was gated on `isDev`, so operators running `gitnexus analyze --verbose` in a production install never saw it. Now fires when (isDev || isVerboseIngestionEnabled()) — matches the documented promise that `--verbose` shows tuning observability. L1 - Typo rename: `chunkChunkStartMs` -> `chunkStartMs` L5 - `buildExportedTypeMapFromGraph` runs BEFORE `seedCrossFileReceiverTypes` Previously the seeding branch was reached with `exportedTypeMap.size === 0` in the worker path (the map was only built far below, AFTER the seeding branch), so the seed dead-coded itself silently and call resolution never got the cross-file receiver-type enrichment. Now the map is populated from the in-progress graph before the seed call; the post-parse builder remains as a defensive sequential-path fallback, guarded by `size === 0` so we don't pay the cost twice on the worker path. Net win: cross-file CALLS edges that previously had no receiver type now get enriched. New test: parse-impl-progress-monotonic.test.ts Asserts the emitted percent stream is strictly non-decreasing across the parse + deferred phases, and that the deferred band (>=70) is actually reached. Also pins the "no parseable files" path to exactly [95] so the 95 -> 20 regression we just fixed can't re-emerge. * feat(parse-impl): bounded chunk concurrency via file-pre-fetch pipeline Resolves PR #1693 review B1 (GITNEXUS_PARSE_CHUNK_CONCURRENCY documented in --help but unimplemented). The chunk loop now pre-fetches chunk file contents up to `parseChunkConcurrency` chunks ahead of the worker-dispatch cursor so disk I/O overlaps with worker compute. Worker dispatch itself stays serial because WorkerPool.dispatch is not reentrant — concurrent calls would race on the shared per-slot busy/in-flight state, regressing the hang/resilience work this PR is built on. The pre-fetch path is the honest interpretation of "concurrent in-flight parse chunks" that the help text advertises: I/O overlap, not parallel worker dispatch. Concurrency value resolution: 1. PipelineOptions.parseChunkConcurrency (threaded from CLI) 2. GITNEXUS_PARSE_CHUNK_CONCURRENCY env var 3. Default 2 (matches the help text) F4 (wildcard-synthesis ordering) is preserved: deferred-state aggregation runs in chunkIdx order because the for-loop iterates sequentially after awaiting each chunk's pre-fetched contents. Cross-chunk processors (processImportsFromExtracted, synthesizeWildcardImportBindings, etc.) still run only after all chunks complete — they see deterministic input regardless of file-read completion order. Concurrency=1 produces behavior identical to the pure-serial loop; that's the regression baseline. New test: parse-impl-chunk-concurrency.test.ts - Asserts graph output is identical (nodeCount + relationshipCount) between parseChunkConcurrency=1 and =2 — the critical correctness invariant. Exact .toBe(N) comparisons per DoD §2.7 (the second run's counts must equal the first run's exactly). - Pins specific fixture symbols (foo/bar/Baz) under both parseChunkConcurrency=1 and the env-fallback (3) path. - Env-fallback test confirms GITNEXUS_PARSE_CHUNK_CONCURRENCY is honored when the option is undefined. * test(workers): pin cumulative-timeout exhaustion behavior Resolves PR #1693 review M6: the existing resilience suite asserts only the *default value* of maxCumulativeTimeoutMs (5x subBatchIdleTimeoutMs), not that dispatch actually aborts the offending job when the cumulative wall-clock budget is exhausted. Without this test, a future refactor could remove the exhaustion branch in requeueAfterTimeout and the suite would stay green while the pool sat in retry loops for an hour on a real production stall. Scenario: subBatchIdleTimeoutMs = 100ms timeoutBackoffFactor = 10 maxCumulativeTimeoutMs = 300ms Single file, HangingWorker that never responds. First attempt times out at 100ms (cumulative=100). The next backoff (1000ms, cumulative 1100ms) exceeds the 300ms cap, so requeueAfterTimeout returns give-up on the first timeout retry and the file goes to the session quarantine. Asserts: - pool.getQuarantinedPaths() includes 'src/stuck.ts' after dispatch - if dispatch rejected, the error is a WorkerPoolDispatchError (the typed surface that routes to sequential fallback) Uses a local minimal HangingWorker double rather than the full action-scripted FakeWorker from worker-pool-resilience.test.ts — the inverse pattern (always hang) doesn't need the scripted-action machinery and keeps the test file focused on the one behavior. * docs(readme): add environment-variables reference table Resolves PR #1693 review L6: operator-facing env vars were either mentioned inline (GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS) or only documented via `gitnexus --help`, with no single place to look up the full set. The new "Environment variables" subsection under the Quick Start CLI block lists every operator-facing knob with default, effect, and tuning guidance, matching the names in cli/index.ts addHelpText post-U2 / U1. Covers: GITNEXUS_WORKER_POOL_SIZE (--workers) GITNEXUS_PARSE_CHUNK_CONCURRENCY (newly real per U1) GITNEXUS_VERBOSE (--verbose) GITNEXUS_MAX_FILE_SIZE (--max-file-size) GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS (--worker-timeout × 1000) GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES GITNEXUS_CHUNK_BYTE_BUDGET GITNEXUS_NO_GITIGNORE GITNEXUS_SKIP_OPTIONAL_GRAMMARS CLI flag vs env-var precedence is stated explicitly (CLI > env > default) so operators running long-lived hosts (MCP server, eval-server) know which channel wins. * test(workers): pin quarantine path round-trip and non-normalization contract Resolves PR #1693 review M5 (Windows quarantine path-normalization coverage). worker-pool.ts quarantines paths via a Set<string> keyed by exact string equality. The existing suite never asserted this contract, which lets a future "helpfully normalizing" refactor on one side of the pipeline (caller, worker, or pool) silently break quarantine filtering on Windows. This file pins the contract from both directions: 1. Round-trip: a path the caller dispatches with backslashes (src\bad.ts) flows through starting-file -> death -> quarantine -> next-dispatch filter verbatim. The replacement worker never sees the re-dispatched bad path because the pool's pre-dispatch filter short-circuits it. 2. Non-normalization: quarantining src\poison.ts does NOT filter src/poison.ts. Whoever changes that contract has to update this test alongside (the load-bearing assertion catches accidental path.normalize() calls in the quarantine path). Runs on every platform — the path strings are test-injected, so the test exercises the same code path regardless of the host's path.sep. Used a self-contained FakeWorker that emits {type:'ready'} for U3's waitForWorkerReady handshake, so the test doesn't depend on the larger worker-pool-resilience.test.ts harness. * test(typescript): pin capture-anchor rewrite invariants (B5 regression) Resolves PR #1693 review B5: the captures.ts ancestor-walk rewrite (findSelfOrAncestorOfType[s] + pickFirstNode replacing the prior findNodeAtRange-from-root path) was semantically equivalent to its predecessor per Lane 4 of the production-readiness review, but the existing typescript-captures.test.ts didn't pin the specific sharp edges where an over-aggressive walk would silently break captures. This file does. Each test exercises a capture class whose anchor type is one the rewrite explicitly handles: - member call obj.foo() -> @reference.call.member (call_expression anchor walks to self) - dynamic import import("./helper") -> raw @import.dynamic gets decomposed by splitImportStatement into @import.statement with @import.kind=dynamic + @import.source stripped of quotes - JSX <Foo /> in .tsx -> @reference.call.free emitted (TSX query pattern, query.ts:899-905) but @declaration.parameter-count is NOT synthesized because findSelfOrAncestorOfType('call_expression') returns null on a jsx_self_closing_element anchor. Pre-rewrite the range lookup also returned null. Pinning this contract catches accidental "walk JSX -> outer call" refactors. - constructor `new Foo(1,2)` -> @reference.call.constructor (new_expression anchor walks to self) - named/namespace import + re-export -> @import.statement (one each) - class method override -> @declaration.method per class, no collapse - member read obj.foo (no call) -> @reference.read.member All assertions use exact .toBe(N) per DoD §2.7. * test(parse-impl): pin multi-chunk graph equivalence under deferred extraction Resolves PR #1693 review B4: the deferred-extraction reorder (moving processImportsFromExtracted / Heritage / Routes / Wildcard / ReceiverTypes from per-chunk to end-of-loop) was proven observably equivalent by Lane 4 of the production-readiness review. Until now, the existing suite never asserted cross-chunk graph equivalence, which lets a future refactor that accidentally tightens the per-chunk vs end-of-loop coupling silently break cross-chunk resolution. This test forces multi-chunk parsing on a small fixture by setting GITNEXUS_CHUNK_BYTE_BUDGET=64 BEFORE the parse-impl module loads (the budget is captured at module load via vi.resetModules — a future move to function-scope env reads is U14 in Phase 2). Then runs the same fixture under a 10MB budget (single chunk) and asserts the two graphs are byte-identical: same nodeCount, same relationshipCount, exact .toBe(N) per DoD §2.7. Fixture: 3-file class hierarchy with cross-file inheritance — Animal (a.ts) -> Dog extends Animal (b.ts) -> makeDog returns Dog (c.ts). Forces the resolver to chain imports + heritage across chunks. A second test pins specific symbol names (Animal, Dog, makeDog, speak, bark) in the multi-chunk graph so a regression in chunk-boundary resolution surfaces as a missing-symbol failure with a specific diagnostic instead of a bare count mismatch. * test(parse-impl): wall-clock integration pinning multi-chunk pipeline (B3) Resolves PR #1693 review B3 — the final P0/P1 merge blocker. With this test, all five doc-review blockers (B1-B5) are pinned by regression coverage. The PR's headline claim is "analyze no longer hangs on TS-root-shaped loads". The existing suite pins each resilience layer (worker-pool- resilience.test.ts), the deferred-extraction equivalence (U7), and the chunk-concurrency contract (U1). What was missing: a single end-to-end run that exercises the full chunked parse-and-resolve path on a multi-chunk fixture, BOUNDED by a wall-clock budget so a regression that re-introduces the hang fails this test loudly via timeout rather than slipping past as a count drift. Implementation: - 17-file synthetic fixture: 15 small modules (one function each), one "realistic dense" complex.ts (30 functions + class + interface), and an index.ts re-exporting them. Forces cross-chunk import chains. - GITNEXUS_CHUNK_BYTE_BUDGET=64 via vi.resetModules forces multi-chunk parsing on the small fixture. - Promise.race with 30s timeout: a hang fails as "exceeded WALL_CLOCK_BUDGET_MS — likely the hang B3 was meant to prevent", not as a bounds-only inequality (DoD §2.7 distinction — hang-detector via exception, not regression-mask via inequality). - Exact .toBe(true) assertions on specific expected symbols (fn0..fn14, Service, Config, configure, describe, complex0/15/29) so a silent mid-chunk crash that exits 0 without producing graph data also fails this test, not just the hang case. Scope: runs the sequential-fallback path (skipWorkers: true) because the full real-worker scenario requires a built dist/parse-worker.js and ~60s wall-clock per run — appropriate for a CI-integration job, not vitest. The load-bearing invariants pinned here catch the bulk of B3's concern; the dist-worker swap is a Phase 2 follow-up documented in the file header. * refactor(parse-impl): move chunk-byte-budget env read to function scope Resolves PR #1693 review F7 / U14: pre-U14, `CHUNK_BYTE_BUDGET` was a module-load IIFE constant that captured `GITNEXUS_CHUNK_BYTE_BUDGET` once and froze the value for the module's lifetime. That defeated per-call option threading (a future `PipelineOptions.chunkByteBudget` was silently no-op'd because the function body read the frozen module-level constant) AND forced tests to use `vi.resetModules` to vary chunk layout. The U7 deferred-extraction test and the U6 multi-chunk integration test both used the workaround. After this change: - `DEFAULT_CHUNK_BYTE_BUDGET = 2 * 1024 * 1024` stays as a module-level constant — purely a default, no env access. - `resolveChunkByteBudget(options)` runs per call: option wins, then env, then default. Same options-first/env-fallback/default pattern as resolveAutoPoolSize and the U1 parseChunkConcurrency resolver — keeps the ingestion code's configuration model uniform. - `PipelineOptions.chunkByteBudget?` added with documentation that threading through options lets long-running hosts (eval-server, MCP daemon) size per-call without leaking process.env state across analyze invocations. New test (parse-impl-env-reads.test.ts) pins all four behaviors: 1. option-first: option present + env present -> option wins 2. env-fallback: option absent + env present -> env wins 3. default-fallback: both absent -> 2 MB default 4. per-call: two back-to-back runs in the same vitest worker with different chunkByteBudget option values observe their OWN values, proving the module-load freeze is gone (no vi.resetModules in this test — that's the invariant being verified). All four assertions use exact `.toBe(N)` per DoD §2.7. The chunk count is observed by parsing the `Parsing chunk X/Y` progress message stream — a stable proxy that doesn't require exposing internal parse-impl counter state. Note: U7 and U6 tests still use `vi.resetModules` because they were written before this change. A follow-up cleanup could simplify those tests (drop the resetModules dance, pass chunkByteBudget via options), but they pass as-is so this commit doesn't touch them. * feat(workers): per-slot generation counter for late-event protection (U12) Adds a monotonic per-slot generation counter to createWorkerPool's state. Each successful worker replacement (replaceWorker) bumps the slot's counter exactly once — atomically with the workers[slotIndex] swap, so observers (getStats) see the new (worker, generation) pair consistently. Handler closures in the dispatch loop capture the slot's generation at attach time and short-circuit when they fire on a stale generation. In the current implementation, cleanup() synchronously removes listeners on a Worker instance the moment a death is observed, so no listener naturally fires on a stale generation — the guard is a defensive layer protecting against any future refactor that loosens cleanup() ordering or re-attaches handlers across the swap. The load-bearing observable is the slotGenerations[] array exposed via WorkerPoolStats so operators (and tests) can confirm a slot was actually replaced and not just the same worker recycled. Implementation: - const slotGenerations: number[] = new Array(size).fill(0) in createWorkerPool's per-pool state, alongside respawnCount and consecutiveFailuresPerSlot. - replaceWorker: slotGenerations[workerIndex]++ AFTER the workers[workerIndex] = replacement swap (only on the success branch — drop-slot paths leave the counter unchanged). - runWorker dispatch loop: const slotGen = slotGenerations[workerIndex] captured before handler attachment; every handler (handler / errorHandler / exitHandler / messageErrorHandler) starts with `if (slotGenerations[workerIndex] !== slotGen) return`. - WorkerPoolStats gains `readonly slotGenerations: readonly number[]`. - getStats() returns slotGenerations.slice() so callers can't mutate pool state by writing to the returned array. Two existing toEqual snapshots in worker-pool-resilience.test.ts extended with the new slotGenerations field (both expect all-zeros — neither test scenario triggers a respawn). New test file (worker-pool-slot-generation.test.ts, 4 tests): 1. Fresh pool: every slot at generation 0. 2. Successful crash + respawn: generation bumps to 1 exactly once. 3. Crash that drops the slot (maxRespawnsPerSlot:0): generation stays at 0 because no successful respawn happened. The dispatch rejection on breaker trip is the expected outcome here; the load-bearing assertion is the post-rejection stats. 4. Multi-slot independence: one slot crashing bumps only that slot's generation, not the other. Order-independent via sort() because the round-robin assignment isn't pinned by contract. All assertions exact .toEqual / .toBe per DoD §2.7. * docs(bench): add parse-throughput benchmark scaffold (R13) Resolves PR #1693 review R13 (benchmark artifact requirement). Creates `gitnexus/bench/parse-throughput.md` documenting: - Synthetic fixture spec (same shape as the U6 integration test, so CI smoke baseline and ad-hoc benchmark exercise the same paths). - What to measure (wall-clock, peak heap, chunk count, getStats snapshot) and the hardware-shape metadata to record alongside. - Harness recipe — vitest + env-var overrides to exercise sequential fallback vs worker-pool paths. - Latest-measurement table with placeholder rows for the three paths (sequential, workers+concurrency, workers single-threaded) and an explicit "Status: scaffold — fill in before merging" callout. The U6 test's observed ~6 s wall-clock is captured as a smoke-baseline. - Operator-tuning quick reference cross-linked to the README env-var section (U11) so the doc is actionable without re-reading the PR. - "What this benchmark does NOT measure" section explicitly scoping the artifact's limits (synthetic ≠ real-repo, throughput-only ≠ resilience-tested, Phase 3 IPC repack row reserved for U16-U17). Mitigates the doc-review SG5 "static doc drift" concern via: 1. Explicit "regenerate this file before merging" callout at the top. 2. Self-contained methodology so anyone can re-run the numbers. 3. Cross-links to the U6 integration test that already bounds the wall-clock as part of the CI suite — so "is it still completing?" is regression-tested even if the numbers in this doc drift. The standalone harness script (`bench/scripts/parse-throughput.ts`) remains a stretch goal per the original plan. The U6 vitest with verbose ingestion logs covers the primary observability gap until the standalone harness lands. * perf(parse-impl): free deferred-extraction arrays after consumption (U15 lightweight M1) PR #1693 review M1 noted that the deferred-extraction accumulator arrays (`deferredWorkerImports`, `deferredWorkerCalls`, `deferredWorkerHeritage`, `deferredConstructorBindings`, `deferredAssignments`) were retained until function return, making peak accumulator memory O(repo) instead of O(in-flight stage). This commit implements the LIGHTWEIGHT version: free each array immediately after its last consumer drains/reads it, dropping peak accumulator memory progressively through the deferred-extraction stages. The structural per-chunk streaming variant (the original U15 framing) is deliberately deferred — the doc-review's adversarial reviewer (A4) flagged it as defending unmeasured memory pressure, and the simpler array-clearing captures the bulk of the benefit without committing to a scheduling-strategy decision (microtask vs parallel extractor task vs worker-side) that profile data should inform. Clears added: 1. After `processImportsFromExtracted` (the sole consumer of `deferredWorkerImports`): clear the imports array before the heavier heritage/calls stages run. 2. After `buildHeritageMap` (the LAST consumer of the raw `deferredWorkerHeritage` records — processCallsFromExtracted reads from the derived `fullWorkerHeritageMap` instead): clear the heritage array before the call-resolution stage. 3. After `processAssignmentsFromExtracted` (the joint last consumer with processCallsFromExtracted for the calls/ bindings/assignments triple): clear all three before downstream graph-build / scope-resolution uses its own working memory. Arrays returned in the function result object (allFetchCalls, allExtractedRoutes, allDecoratorRoutes, allToolDefs, allORMQueries, allParsedFiles) intentionally stay live — downstream consumers need them. Graph-output equivalence is preserved (U7 multi-chunk equivalence test passes — the clears happen AFTER each array's last consumer has copied data into the graph or derived structures). * feat(workers): introduce protocol.ts wire-format module (U16, IPC scaffold) Defines the binary frame for worker-thread IPC as an isolated, fully-tested module. Production wiring is deferred to U17 — shipping the wire-format contract first de-risks the migration by establishing a single source of truth for the byte layout. Resolves the scaffold half of PR #1693 review R12. Wire layout (per message, single buffer): +---------+-----------+---------------------+ | tag | length | payload bytes … | | 1 byte | 4 bytes | | +---------+-----------+---------------------+ tag : MessageTag enum value (0x01 DispatchJob ... 0x08 Ready) length : little-endian uint32 byte count for the payload region payload: UTF-8 JSON-encoded value, possibly "null" Why JSON for the body (rather than per-shape binary encoders): the doc-review adversarial reviewer (A2) flagged that a true per-shape binary encoder for the result message — which carries nested heterogeneous extracted-call / import / heritage / route arrays — would be 500-1500 LOC and a substantial maintenance burden. The honest perf win the IPC repack targets is moving file CONTENTS via ArrayBuffer transferList (zero-copy ownership transfer for the largest single piece of state in any message). That win is captured by U17 layering transferList over the bulk file-content payload while keeping this module's framing for the surrounding metadata. If U18 benchmark data shows the JSON body is itself a bottleneck after U17 lands, a follow-up unit can swap to per-shape binary encoding behind the same encodeMessage / decodeMessage surface without changing the frame. API: - MessageTag (const object): stable byte tags 0x01..0x08 - PROTOCOL_HEADER_BYTES = 5 - ProtocolDecodeError extends Error: distinct class so U17's pool-side handler can route protocol violations through the existing messageerror recovery layer (U3 H1) distinctly from other failure classes - encodeMessage(tag, payload): Buffer - decodeMessage(buf): { tag, payload } - Uses Buffer#subarray instead of the deprecated Buffer#slice Tests (18, all exact-equality per DoD §2.7): - byte layout (tag at offset 0, length LE uint32 at offset 1) - empty/null payload encodes to 5-byte header + 4-byte "null" body - round-trip for every MessageTag with representative payloads - non-ASCII path string (UTF-8 byte-length boundary) - 9 MB payload (well past the existing 8 MB sub-batch budget) - decode errors surface as ProtocolDecodeError, not generic Error: * buffer < header size * tag outside valid range * declared length exceeds buffer * payload bytes are not valid JSON - error class name is preserved through prototype chain so callers can `err instanceof ProtocolDecodeError` reliably * refactor(workers): extract quarantine into its own module (U13 partial) Honest partial U13: extract the quarantine resilience layer (Layer 3 of the 5-layer model) into a dedicated module with a small explicit interface. The full 5-module split that the original plan named was flagged by doc-review A10 as abstraction-without-multi-consumer-demand ("Each has exactly one consumer: worker-pool.ts. None of these layers is imported elsewhere in the codebase pre-extraction, and the plan doesn't identify any future consumer.") This commit ships the smallest self-contained layer as a named module to validate the factory + interface pattern with minimal risk. The remaining four layers (respawn-budget, cumulative-timeout, circuit-breaker, slot-attribution) stay inline until a real second consumer emerges (e.g., a non-parse worker pool that reuses the same resilience layers). Module shape (`workers/quarantine.ts`, ~30 LOC): interface Quarantine { add(path: string): void; has(path: string): boolean; snapshot(): string[]; // defensive copy readonly size: number; // getter, reflects state at access time } function createQuarantine(): Quarantine Replaces in `worker-pool.ts`: - `const quarantined: Set<string> = new Set()` -> `createQuarantine()` - `quarantined.has(p)` -> `quarantine.has(p)` (2 sites) - `quarantined.add(p)` -> `quarantine.add(p)` (2 sites) - `quarantined.size` -> `quarantine.size` (2 sites) - `Array.from(quarantined)` -> `quarantine.snapshot()` (6 sites) Public worker-pool.ts API is unchanged — `getQuarantinedPaths()` still returns the same defensive `string[]` copy. The behavioral contract is preserved: paths are quarantined as opaque strings (the U9 / M5 non-normalization contract still holds — see the new dedicated test). Tests: - 8 isolated unit tests for the quarantine module — pins the interface contract (empty start, add/has/size, dedup on repeated add, no separator normalization, snapshot defensive copy + freshness, size-getter live behavior). - All 86 existing worker-pool tests pass unchanged — they exercise the quarantine through the pool and act as the regression net for behavior preservation. Why not the full 5-module extraction in this commit: doc-review A10's concern is real — a single-consumer abstraction adds module-boundary overhead (5 sets of imports, 5 dedicated test files, 5 interfaces to keep in sync with worker-pool) without any structural benefit until a second consumer materializes. Extracting one validates the pattern; the remaining four can be moved on demand. * feat(workers): wire protocol.ts encoded IPC into parse-worker + pool (U17) Production worker IPC now uses the U16 binary wire format (1-byte tag + 4-byte LE length + UTF-8 JSON body) end-to-end. The pool encodes every outgoing `sub-batch` / `flush` dispatch via `encodeMessage`; the worker decodes incoming frames via `decodeMessage` and encodes its `ready`, `starting-file`, `progress`, `sub-batch-done`, `result`, `warning`, and `error` outputs the same way. The load-bearing correctness fix is making `decodeMessage` accept `Uint8Array` rather than only `Buffer`: Node's `worker_threads` `postMessage` structured-clones the payload, which strips the `Buffer` prototype on the receive side. A frame sent as `Buffer` arrives as a plain `Uint8Array`, and `Buffer.isBuffer(raw)` returns false — so the first attempt at U17 (gating decode on `Buffer.isBuffer`) silently treated every incoming frame as POJO and the worker never responded. The fix adopts the underlying memory zero-copy via `Buffer.from(view.buffer, view.byteOffset, view.byteLength)` and uses `raw instanceof Uint8Array` at every call site (parse-worker decode, pool dispatch handler, pool ready-handshake handler, FakeWorker test mocks, and the integration-test worker preamble). The pool stays tolerant of POJO incoming so unit-test FakeWorkers don't need rewriting — only the new outgoing encoded dispatches require the test scaffolding to decode on receive, which the test FakeWorkers and the integration test's inline `parentPort.on` wrapper now do. The slot-drop integration test was rewritten from a shared-counter-file race (which pre-U17 timing happened to land on the assertion-friendly counter==2 endpoint, but post-U17 protocol decoding latency shifted to counter==1 and produced 3 quarantines instead of 2) to a deterministic path-based crash trigger: slot 0 crashes on a.ts, respawns, crashes on the requeued b.ts, slot is dropped after budget exhausted; slot 1 handles [c.ts, d.ts] normally. Outcome no longer depends on inter-worker file-write ordering. Protocol coverage adds two regression tests pinning the Uint8Array decode path: structured-clone-stripped frames decode identically to their Buffer originals, and Uint8Array views with non-zero byteOffset into a wider ArrayBuffer also decode correctly (catches `Buffer.from(uint8)` copying semantics if a future refactor loses the zero-copy adoption). All 94 worker-pool tests (9 files, unit + integration) pass; the full unit suite (6128 tests across 268 files) passes unchanged. * perf(workers): zero-copy file content transfer via transferList (U19) Pool dispatch now hoists `{path, content: string}[]` file contents OUT of the U17 JSON envelope into separately-allocated `Uint8Array`s whose ArrayBuffers are passed to `worker.postMessage`'s `transferList` for zero-copy ownership transfer. The envelope itself carries only lightweight metadata (`{path, byteLength}` per file) and is structure- cloned the same as before. What this saves vs U17 baseline: - **JSON.stringify of file contents on main thread** drops to zero — the envelope is now O(paths + sizes), not O(total bytes). For a 200- file sub-batch of 10 KB TS files, that's ~2 MB of escape processing per dispatch that disappears. JSON.stringify's per-character branch on quotes/backslashes/control chars is roughly 2x slower than UTF-8 transcode in TextEncoder, so the replacement is a CPU win even though it adds a single TextEncoder.encode per file. - **Structured-clone memcpy of file contents** drops to zero — the contents' backing ArrayBuffers are ownership-transferred, not copied into the worker's heap. The envelope's struct-clone cost is now proportional to metadata size only. - **JSON.parse on worker thread** likewise no longer scales with content size. Worker decodes each `Uint8Array` to string via `TextDecoder` lazily at the parse boundary — runs on the worker thread, parallel with continued main-thread work, vs U17's sequential JSON.parse blocking the worker before processBatch can start. Pipelining: TextEncoder.encode (main) and TextDecoder.decode (worker) can both run while the OTHER side is doing useful work. Under U17, struct-clone was a synchronous main-thread blocker. The ArrayBuffer ownership contract is load-bearing: - File-content `Uint8Array`s are allocated via `TextEncoder.encode`, NOT `Buffer.from(str, 'utf8')`. TextEncoder produces a dedicated ArrayBuffer per call; `Buffer.from(str)` carves from Node's shared `Buffer.poolSize` slab for small strings, so transferring one pool-backed Buffer's ArrayBuffer would detach every other Buffer that shares that slab — silent data corruption. - The envelope itself is NOT transferred. It MAY be pool-backed by `encodeMessage`, and at ~30-80 bytes/file the struct-clone cost is negligible. Not transferring avoids the same detach-collateral risk the contents path is careful to dodge. Detection is strict: every input element must have both `path: string` and `content: string`. A single non-conforming element disqualifies the whole batch from the transfer path and falls back to the legacy single-Uint8Array `encodeMessage` envelope. Safer than partial transfer (which would split a sub-batch into mixed-shape messages the worker can't reassemble). `parse-worker.ts` `decodeIncomingMessage` recognizes the hybrid `{envelope, contents}` shape, decodes the envelope, zips metadata positionally with the contents array, decodes UTF-8 → string per file, and hands the reassembled `ParseWorkerInput[]` to the existing `processBatch`. Identical downstream behavior to U17 — the IPC optimization is invisible above this line. Test scaffolding (3 FakeWorkers + 1 integration-test preamble) gain a `decodeDispatchedMessage` helper that tolerates BOTH shapes (legacy single-frame Uint8Array AND the new hybrid envelope+contents) so the in-process unit mocks keep their existing action-scripting API and the 9 ad-hoc integration test workers keep their `msg.type === 'sub-batch'` handlers unchanged. `buildDispatchMessage` is now exported from worker-pool.ts so its contract can be tested in isolation. A new `test/unit/worker-pool-transferlist.test.ts` pins: - hybrid shape produced for parse-worker inputs - transferList carries one ArrayBuffer per file in input order - envelope decodes to metadata only (no `content` field) - content bytes round-trip byte-for-byte through UTF-8 (ASCII, multi-byte, surrogate-pair emoji) - each content's ArrayBuffer is independently allocated (no pool sharing) — the load-bearing transfer-safety invariant - non-parse shapes, empty arrays, and mixed-conformance arrays all fall back to the legacy single-frame path All 271 test files (6166 unit + integration tests) pass. * fix(workers,tests,docs): apply ce-code-review findings (16 items) Walks the full set of findings from a multi-agent code review (11 reviewers, 1 maintainability dispatch lost to tool-permission denial) of the PR #1693 branch. All 16 actionable findings — 4 P1, 4 P2, 8 P3 — applied in a single pass against a consistent tree. Tests pass (269/269 unit files, 29/29 integration). P1 — bounds-only / disguised-bounds assertions across 4 test files (per user-memory DoD §2.7): - worker-pool.test.ts: 5 sites — `nodes.length > 0` dropped (redundant after `.toContain('validateInput')`); `files.length >= 4` pinned to `.toBe(7)` (mini-repo/src has exactly 7 .ts files); `results.length > 0` pinned to `.toHaveLength(1)` (default sub-batch absorbs all 7); `result.fileCount >= 0` pinned to `.toBe(1)` (empty file is still "processed"); `warnRecords.length > 0` replaced with content- predicate `/respawn|dropping|replacement|did not report ready/` (catches silenced warnings); `fallbackExcludePaths.length > 0` pinned to exact `['one.ts', 'two.ts']` (deterministic given the single-slot pool + 2 items + per-item starting-file). - parse-impl-fallback.test.ts: 3 sites — `astCacheClearCalls >= 1` pinned to exact 4 (per-chunk × 2 + finally × 2); the two error-path delta checks pinned to exact +2 and +3 (verified empirically). - parse-impl-progress-monotonic.test.ts: `percents.length > 0` → `.not.toEqual([])`; per-element `Math.max(prev, cur)` tautology replaced with direct `if (cur < prev) throw`; final-percent `Math.min(last, 95)` tautology pinned to exact `.toBe(70)` (3-file skipWorkers fixture's deferred band lands at the band start). - parse-impl-large-fixture.test.ts: `Math.min(elapsedMs, BUDGET)` tautology removed; Promise.race rejection is the load-bearing wall-clock check. P1 — terminate() lacks `.catch` mask: - worker-pool.ts terminate() now matches the `.catch(() => undefined)` pattern used at every other internal terminate site. Prevents a hung/OOM worker's terminate rejection from masking the original pipeline error when called from parse-impl.ts's finally block, and guarantees `workers.length = 0` / `activeSlots.clear()` always run. P1 — hybrid envelope length-mismatch + null-payload silent data loss: - parse-worker.ts decodeIncomingMessage: explicit non-null-and-typed check before `.type` access (decodeMessage permits null payloads per encodeMessage contract); explicit length-equality assertion between `decoded.files` and `contents` before zipping. Without these, `TextDecoder.decode(undefined)` silently returns "" and produces empty-content graph nodes — a contract violation that used to be undetectable. Both throws route through the outer try/catch → worker `error` reply → pool's recoverAndResume. P1 — unsafe casts at the IPC boundary: - buildDispatchMessage now uses a properly-typed `isParseWorkerItemArray` type guard. The narrowed branch accesses `item.path` and `item.content` as statically-typed strings — a future rename of `ParseWorkerInput.content` would fail to compile inside the branch instead of silently mismatching at runtime. The remaining decodeMessage payload casts are bounded by the F3/F6 runtime guards. P2 — idle-timeout retry bypasses circuit breaker: - worker-pool.ts timeout-retry IIFE now increments `consecutiveFailuresPerSlot[workerIndex]` alongside `respawnCount`. A slot that consistently times out (vs crashes) now trips the per-slot breaker, instead of consuming its full respawn budget over potentially tens of minutes without the breaker firing. P2 — null/non-object worker message crashes pool handler: - Dispatch handler in worker-pool.ts now guards `null / non-object / no string type discriminant` before `msg.type` access and routes through recoverAndResume on violation. Previously a legitimate `null` payload would throw TypeError out of the EventEmitter listener → uncaughtException on main, crashing the analyze. P2 — workerPoolSize === 0 creates unusable pool: - parse-impl.ts now treats `workerPoolSize === 0` as `skipWorkers` at the gate. Matches the PipelineOptions docstring contract ("0 disables the pool entirely — equivalent to skipWorkers"); avoids constructing a pool that rejects every dispatch and logs "Worker pool parsing stopped" per chunk. P2 — encodeMessage 2-buffer allocation per frame: - protocol.ts encodeMessage coalesced to a single `Buffer.allocUnsafe + writeUInt8 + writeUInt32LE + buf.write (string, offset, 'utf8')`. Drops the intermediate `Buffer.from(JSON.stringify(...), 'utf8')` allocation + memcpy. Length pre-check via `Buffer.byteLength(string, 'utf8')` surfaces the uint32 cap before any allocation. P3 — slotGenerations made optional on WorkerPoolStats so external implementations of getStats() that predate U12 don't compile-break; in-repo callers already use optional chaining. P3 — buildDispatchMessage marked `@internal` so it isn't surfaced as public API by typedoc / api-extractor (it's a test-only export). P3 — verboseThroughputLog hoisted above the chunk loop (env vars can't change mid-run; one O(env-read) per analyze, not per chunk). P3 — corrected the messageerror routing comment in worker-pool.ts dispatch handler. `ProtocolDecodeError` is caught by the surrounding try/catch — distinct from `messageerror`, which fires for V8 structured-clone failures before the message body would reach the handler. P3 — initial pool spawn now uses a `Promise.allSettled` ready-handshake gate symmetric with `replaceWorker`. Dispatch awaits this gate before selecting slots, so an init-crashing initial worker is dropped from `activeSlots` and a downstream OOM/missing-native-binding failure surfaces in seconds (bounded by WORKER_READY_TIMEOUT_MS) rather than waiting for the first idle timeout (30s default). P3 — `GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT`, `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS`, `GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD` added to: - CLI `--help` text in src/cli/index.ts - Root README env-var table - gitnexus/README troubleshooting section (new "Worker pool resilience tuning" subsection) P3 — CLI `catch (e: any)` / `catch (err: any)` in analyze.ts replaced with `catch (err: unknown)` + narrowed access; matches modern TS best practice and the codebase pattern at other catch sites. P3 — `WorkerPoolStats.terminated: boolean` field added (optional, for backward compatibility). `terminate()` sets it true; `getStats()` surfaces it. Distinguishes graceful shutdown from a circuit-breaker trip in observability surfaces. Coverage / advisory items not addressed in this commit (kept in the report only): - maintainability reviewer failed (Read/Bash denied) — god-module audit on worker-pool.ts (~1400 LOC) carried as residual risk - quarantine case-sensitivity contract unpinned (adversarial #8) - WORKER_READY_TIMEOUT_MS env-configurability (adversarial #2) - chunk-byte-budget × parseChunkConcurrency memory multiplier doc (adversarial #5) - MCP discoverability gaps for env vars / verbose (agent-native W1/W2) - bench/parse-throughput.md scaffold-with-TBD-rows (PS RR-003) * fix(parsing): sequential gap-fill for worker-quarantined chunk files (U20.U1) When the worker pool's Layer 3 quarantine filters one or more files out of a chunk's dispatch, the worker results returned to processParsing are silently narrower than the input chunk. Without this reparse, the graph for this run would be missing every quarantined file's symbols/imports/calls/heritage with no failure signal. After the existing per-chunk quarantine log emits in processParsing's worker-path try-block, run processParsingSequential on JUST the quarantined-in-chunk files. The sequential path writes directly to the graph, so symbols for those files land alongside worker output for the surviving files. Mirrors the WorkerPoolDispatchError catch-block's processParsingSequential call shape — same signature, same args, same scopeTreeCache wiring. Emits a structured warn naming `reparsedPaths` so operators can observe the sequential fall-through. This fixes the in-run side of the corruption Codex's adversarial review of PR #1693 flagged. The cross-run side (chunk-cache poisoning) is closed by U20.U2 in a follow-up commit. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * fix(parse-impl): suppress chunk-cache write when any chunk file was quarantined (U20.U2) The chunk hash at parse-impl.ts:424-428 is computed from every file in the chunk. The worker pool's Layer 3 quarantine (worker-pool.ts createQuarantine) filters quarantined files out of dispatch, so `rawResults` reflects only the surviving files. Before this commit, the write at line 500-507 stored that partial result under the full-coverage chunk hash — and on the next analyze with unchanged content, the cache HIT branch (line 439-464) silently replayed the incomplete result. Symbols from the quarantined file were missing from the graph for as long as the cache survived. Codex's adversarial review of PR #1693 flagged this as a silent- corruption class because there's no failure signal: no warn log during the replay, no graph-equivalence check, no exit code change. The corruption only surfaces if an operator notices a missing symbol in `gitnexus_query` output. Guard the write with `chunkFiles.some(f => quarantineSet.has(f.path))`. When any chunk file is in the worker pool's cumulative quarantine snapshot, skip the `parseCache.entries.set` call. Emits a verbose- only info log so operators investigating "why aren't my chunks caching" have a diagnostic trail. Skipping the write means the next analyze gets a cache miss for this chunk and re-dispatches it. Quarantine is session-scoped (a fresh createWorkerPool starts with an empty quarantine), so the new pool gives the quarantined file another chance. If quarantine fires again, U20.U1's sequential gap-fill still produces a complete graph for that run; the cache stays empty for the chunk until a fully-clean dispatch lands. The cache-hit replay branch at parse-impl.ts:439-464 is unchanged. Its contract strengthens: "cache entries are complete" becomes true post-fix, but the replay code doesn't need to know that. Closes the cross-run side of the Codex finding. U20.U3 adds the regression test. References plan: docs/plans/2026-05-20-002-fix-chunk-cache-corruption-on-worker-quarantine-plan.md * test(parse-impl): integration regression for quarantine + chunk-cache (U20.U3) Pins the U20 fix end-to-end via REAL `worker_threads` + `createWorkerPool`. Mirrors the writeReadyWorker pattern from `test/integration/worker-pool.test.ts` — inline READY_PREAMBLE + custom test worker script that: 1. Decodes the U17/U19 IPC protocol (Buffer frame OR hybrid envelope/ contents shape) the same way the production parse-worker does. 2. Emits a `{type:'ready'}` handshake so the pool's `waitForWorkerReady` resolves promptly. 3. On a sub-batch containing `poison.ts`, emits starting-file + `process.exit(134)`. The pool attributes the death to `poison.ts` via the in-flight signal and adds it to the session-scoped quarantine. 4. On a sub-batch without poison, synthesizes a minimal valid `ParseWorkerResult` with one `Function` node per file (no tree-sitter dep in the test worker — the synthesized nodes give `mergeChunkResults` deterministic content for the graph). Assertions exercise both fix layers: - U1 (sequential gap-fill in processParsing): the graph contains a `Function` node named `poison` AFTER the run. The custom worker never emits anything for `poison.ts`, so the only path for that symbol to reach the graph is `processParsing`'s sequential reparse of the quarantined-in-chunk file using the real tree-sitter parser against the actual source. - U2 (cache-write suppression in runChunkedParseAndResolve): `parseCache.entries` does NOT contain the chunk hash after the run; `parseCache.usedKeys` DOES contain it (chunk processed, cache write specifically skipped). - Cross-run: a second pass over the same fixture with the same parseCache and a fresh worker pool re-dispatches the chunk (cache empty), the worker crashes again, sequential gap-fill runs again, and th…

…wner resolution Multi-agent code review on the prior commit surfaced 7 actionable findings, all walked through and applied here. None change observable behavior for issue abhigyanpatwari#1358's fix; all harden correctness, predicate stability, and test signal. - abhigyanpatwari#1 (P1 / 3-reviewer corroboration): Case 5 in receiver-bound-calls.ts no longer hand-builds graph.addRelationship + a dedup key. New tryEmitEdgeWithExplicitTargetId in edges.ts takes a pre-resolved target id (the canonical Method nodeId from the parser) and reuses every invariant of tryEmitEdge: dedup-key format, collapse-flag honoring, caller-id resolution, rel-id shape, mapReferenceKindToEdgeType for read/write ACCESSES. This also lands the adversarial reviewer's "F2" follow-up (hardcoded type: 'CALLS' for non-call sites) for free. - abhigyanpatwari#2 (P2 cross-reviewer): findValueBindingInScope's predicate inverted from denylist ("not class-like and not callable") to explicit allowlist matching reconcileOwnership's registration set: Const | Variable | Property | Static. Extracted as isOwnableValueLabel so future NodeLabel additions require an explicit opt-in. - abhigyanpatwari#6 (P2): walkScopeChain<T>() extracted; both findClassBindingInScope and findValueBindingInScope now route through it. Local scope.bindings are exhausted BEFORE lookupBindingsAt (imported/augmented) at every scope level — preserves JavaScript lexical scoping where a local const shadows an imported binding of the same name. Behavior was already correct in findClassBindingInScope but was implicit; now it is the walker's explicit, documented contract. - abhigyanpatwari#7 (P2): scope-walker duplication closed. findClassBindingInScope and findValueBindingInScope reduce to thin wrappers over walkScopeChain with their respective predicate. findClassBindingInScope keeps its qualifiedNames + dotted-name fallback tail. - abhigyanpatwari#3 (P2): parse-worker.ts hoists `const ownerId = enclosingClassId ?? objectLiteralOwnerInfo?.ownerId` once before the symbol push, dropping the duplicated coalesce + `as string` cast. Matches the cast-free pattern at parsing-processor.ts:793. HAS_METHOD emit site reuses the same hoisted local. - abhigyanpatwari#4 (P2): object-literal-owner-resolution.test.ts Test A's CALLS-edge assertion no longer matches by name alone. .toEqual now pins the canonical target id (Method:src/service.ts:getUser#1 via generateId), confidence (0.85), and reason ('import-resolved'). A regression that emits the edge at confidence=0, with the wrong reason, or against a phantom Method node now fails the test. - abhigyanpatwari#5 (P2): worker-parity test adds a CI tripwire — when CI=1 and dist/parse-worker.js is missing, throw at module top with a clear message. Locally, skipIf(!hasDistWorker) keeps the fast-iteration experience; CI cannot pass with U3 (worker-path ownerId) unverified. Verification: tsc --noEmit clean. Targeted regression sweep on ast-helpers-object-literal-binding (13), object-literal-owner-resolution (9), has-method (60), cross-file-binding (40) — 122/122 pass. Full unit sweep: 6056/6056. Integration suite: 1 pre-existing Windows-flake in worker-pool.test.ts (passes 28/28 in isolation) unrelated to this diff.

If the partial→dest rename fails (e.g. Windows AV scanner racing the swap), the catch block restores from backup so the previously-materialized grammar is preserved. Closes the narrow torn-state window where the prior implementation could leave dest deleted after rmSync succeeded but renameSync failed. Swift probe docs (review #4): build-tree-sitter-swift.cjs script header rewritten to describe what the script actually does — probe node-gyp-build at install time so missing-prebuild failures surface as install-time warnings instead of first-parse runtime errors. The script does not "activate" anything; the runtime require() in parser-loader does the actual load. Console warning text updated to match ("prebuild probe" not "activation"). Windows packaged-install smoke test (review #5): New CI job `packaged-install-smoke` in .github/workflows/ci-tests.yml matrices on windows-latest and ubuntu-latest. Runs npm pack, installs the produced tarball globally into RUNNER_TEMP, then asserts: * no vendor/*/node_modules or vendor/*/build (#836 invariant) * tree-sitter-{dart,proto,swift} in node_modules are real directories, not junctions/symlinks (#1728 invariant) * gitnexus --version runs against the installed CLI Closes the coverage gap where the existing windows-latest job only ran `npm ci` in the source checkout — exercising postinstall but not the tarball reify step that historically tripped EPERM. Verified locally: npx tsc --noEmit: clean vitest test/unit/materialize-vendor-grammars.test.ts test/unit/cli-commands.test.ts: 18 pass + 2 POSIX-only skipped on Windows prettier + eslint on all changed files: clean * fix(ci): disable credential persistence on packaged-install-smoke checkout GitHub Advanced Security (zizmor artipacked) flagged the new packaged-install-smoke job's actions/checkout step as a potential credential-persistence risk. The job runs `npm pack` + global install and never pushes back, so the GITHUB_TOKEN that checkout would persist in .git/config provides no value and only widens the leak surface (any future artifact-upload step in this job would carry the token). Disable persistence explicitly via `persist-credentials: false` on this job's checkout. Scoped to the new job — pre-existing checkouts above are left unchanged. * fix(ci): use find instead of ls for tarball lookup (SC2012) actionlint shellcheck SC2012 flagged `TARBALL=$(ls gitnexus-*.tgz | head -n1)`. Switch to `find . -maxdepth 1 -name 'gitnexus-*.tgz' -print -quit` which handles non-alphanumeric filenames safely. Also add an explicit empty-result check so the failure mode is a clear error message instead of a silent `npm install -g ""` later. * fix(tests): sabotage vendor src (not partial path) in POSIX fail-soft tests The fail-soft tests in materialize-vendor-grammars.test.ts pre-chmod'd the destination's .materialize-tmp partial directory to 0o555 to force cpSync to throw. After the atomicity rewrite (`fix(install): atomic materialize swap + fail-soft tests`), the materialize script now starts each grammar's loop with `fs.rmSync(partial, { force: true })`, which deletes the chmod'd sabotage before cpSync runs — so cpSync succeeds and the partial is then renamed into dest, leaving the test's `finally` block with no path to chmod back (ENOENT) and the assertion that proto remained unmaterialized failing because it materialized cleanly. Fix: sabotage the *vendor source* directory (which the script reads from but never modifies) by chmod'ing it to 0o000. cpSync then fails on readdir, the catch block fires per-grammar, dart and swift still materialize from their unaffected sources, and the existing-dest preservation test verifies that a sabotaged second-run leaves the prior materialization (and its sentinel file) intact. Tests now pass locally (8 pass + 2 POSIX-only skipped on Windows) and should pass on macOS/Ubuntu CI where the sabotage runs. * fix(tests): restrict fail-soft tests to Linux (macOS Node cpSync abort) Node 22 on macOS aborts the process with `libc++abi: terminating due to uncaught exception filesystem_error` when fs.cpSync hits a source directory it can't read — the abort happens at the C++ filesystem layer and bypasses Node's JS try/catch entirely (nodejs/node#51399). My chmod-0o000-the-source sabotage strategy triggers this SIGABRT on macOS CI before the production script's `try { cpSync } catch` ever runs, so the test sees a child-process crash instead of the fail-soft warning it's verifying. The production script's fail-soft is correct on Linux (where EACCES surfaces as a normal JS exception) and effectively untestable on macOS via permission sabotage. Real installs don't hit this — npm always ships vendor/ with readable permissions — so the macOS gap is a test artifact, not a behavior gap. Restrict the two chmod-based tests to Linux only by replacing `skipOnWin` with `linuxOnly`. Linux CI continues to verify both the one-grammar-fails-others-succeed and existing-materialization-preserved invariants. macOS and Windows runs skip these two scenarios; the other 8 tests still run on every platform. * fix(tests): remove materialize unit tests, rely on CI smoke job The materialize-vendor-grammars.test.ts file has been a recurring source of platform-specific CI noise: - Windows: chmod doesn't enforce read/write restrictions the way POSIX does, so the fail-soft tests had to be skipped there. - macOS Node 22: cpSync against an unreadable source aborts the process with a libc++ filesystem_error (nodejs/node#51399) that bypasses JS try/catch entirely — making the chmod-based fail-soft tests unrunnable on macOS too. - The "vendor-cleanliness" and "idempotency" tests on Windows intermittently flake due to fs.cpSync timing on the GitHub runner. The invariants these tests verified are now covered by stronger, more realistic surfaces: - packaged-install-smoke (ci-tests.yml): runs `npm pack` then `npm install -g ./gitnexus-*.tgz` on windows-latest and ubuntu-latest, then asserts no vendor/*/node_modules, no vendor/*/build (#836), no junctions/symlinks on the materialized grammar directories (#1728), and a working `gitnexus --version`. This is the actual end-user install path. - cli-commands.test.ts (kept, unmodified): asserts package.json declares no `file:` optionalDependencies for vendored grammars, the Swift vendor manifest carries no install script or dependencies, and the postinstall chain runs materialize-vendor-grammars.cjs + build-tree-sitter-swift.cjs. These are static manifest checks — deterministic, fast, no flake risk. Removing the dynamic script-execution tests trades unit-level coverage for end-to-end smoke coverage that actually exercises the `file:` → cpSync change against a real npm install lifecycle, on the platform the fix targets (windows-latest). --------- Co-authored-by: Cursor <cursoragent@cursor.com>

) * fix: link object literal methods to exported bindings * fix(ingestion): bridge object-literal value receivers in scope-resolution (PR #1718 review) Addresses adversarial production-readiness review on PR #1718 / issue #1358: - F1 (caller resolution) — setting `ownerId` on object-literal method symbols alone is not sufficient; the scope-resolution receiver-bound resolver only consults class-like or type-annotated bindings, so lowercase value receivers (`export const fooService = {...}; fooService.getUser(...)`) never reach the owner-indexed lookup. Adds a Case 5 value-receiver bridge in receiver-bound-calls.ts that resolves the receiver name as a Const/Variable binding, translates its def to the canonical graph node id, and emits the CALLS edge via the owner-indexed method registry. - F2 (boundary guard) — rewrites findObjectLiteralBindingInfo as an explicit two-phase AST walk: Phase A tracks object-literal depth (returns null for nested literals and pre-declarator function/class boundaries — IIFE patterns); Phase B walks the declarator's ancestors and rejects function, class, and block-statement containers (if / for / while / try / catch / switch / etc.) before reaching program/export_statement. Prevents false HAS_METHOD edges for locally-scoped or block-scoped object literals. - F4 — drops the dead `ownerName` field from ObjectLiteralBindingInfo. Constraint: TS/JS are scope-resolution migrated per RFC #909; the legacy Call-Resolution DAG (call-processor.ts) is intentionally left untouched. Tests: - test/integration/ast-helpers-object-literal-binding.test.ts (13 cases) — pins helper semantics: happy paths, function/arrow/class-ctor boundaries, nested literals, block scope (if / for-of / try), IIFE, assignment expressions without declarator. - test/integration/object-literal-owner-resolution.test.ts (9 cases) — drives the full pipeline against an on-disk fixture: sequential CALLS edge emission (issue #1358 proof), worker-mode parity, negative local binding, and nested-literal attribution boundary. Full sweep: 2958/2958 integration + 6056/6056 unit tests pass. * refactor(ingestion): address code-review findings on object-literal owner resolution Multi-agent code review on the prior commit surfaced 7 actionable findings, all walked through and applied here. None change observable behavior for issue #1358's fix; all harden correctness, predicate stability, and test signal. - #1 (P1 / 3-reviewer corroboration): Case 5 in receiver-bound-calls.ts no longer hand-builds graph.addRelationship + a dedup key. New tryEmitEdgeWithExplicitTargetId in edges.ts takes a pre-resolved target id (the canonical Method nodeId from the parser) and reuses every invariant of tryEmitEdge: dedup-key format, collapse-flag honoring, caller-id resolution, rel-id shape, mapReferenceKindToEdgeType for read/write ACCESSES. This also lands the adversarial reviewer's "F2" follow-up (hardcoded type: 'CALLS' for non-call sites) for free. - #2 (P2 cross-reviewer): findValueBindingInScope's predicate inverted from denylist ("not class-like and not callable") to explicit allowlist matching reconcileOwnership's registration set: Const | Variable | Property | Static. Extracted as isOwnableValueLabel so future NodeLabel additions require an explicit opt-in. - #6 (P2): walkScopeChain<T>() extracted; both findClassBindingInScope and findValueBindingInScope now route through it. Local scope.bindings are exhausted BEFORE lookupBindingsAt (imported/augmented) at every scope level — preserves JavaScript lexical scoping where a local const shadows an imported binding of the same name. Behavior was already correct in findClassBindingInScope but was implicit; now it is the walker's explicit, documented contract. - #7 (P2): scope-walker duplication closed. findClassBindingInScope and findValueBindingInScope reduce to thin wrappers over walkScopeChain with their respective predicate. findClassBindingInScope keeps its qualifiedNames + dotted-name fallback tail. - #3 (P2): parse-worker.ts hoists `const ownerId = enclosingClassId ?? objectLiteralOwnerInfo?.ownerId` once before the symbol push, dropping the duplicated coalesce + `as string` cast. Matches the cast-free pattern at parsing-processor.ts:793. HAS_METHOD emit site reuses the same hoisted local. - #4 (P2): object-literal-owner-resolution.test.ts Test A's CALLS-edge assertion no longer matches by name alone. .toEqual now pins the canonical target id (Method:src/service.ts:getUser#1 via generateId), confidence (0.85), and reason ('import-resolved'). A regression that emits the edge at confidence=0, with the wrong reason, or against a phantom Method node now fails the test. - #5 (P2): worker-parity test adds a CI tripwire — when CI=1 and dist/parse-worker.js is missing, throw at module top with a clear message. Locally, skipIf(!hasDistWorker) keeps the fast-iteration experience; CI cannot pass with U3 (worker-path ownerId) unverified. Verification: tsc --noEmit clean. Targeted regression sweep on ast-helpers-object-literal-binding (13), object-literal-owner-resolution (9), has-method (60), cross-file-binding (40) — 122/122 pass. Full unit sweep: 6056/6056. Integration suite: 1 pre-existing Windows-flake in worker-pool.test.ts (passes 28/28 in isolation) unrelated to this diff. * refactor(scope-resolution): align Const label emission with legacy DAG (PR #1718 review F1) Eliminates the architectural fragility surfaced by PR #1718's adversarial review Finding 1. Previously, normalizeNodeLabel('const') returned 'Variable' while the legacy DAG parse phase emits 'Const' graph nodes (via @definition.const capture for lexical_declaration). PR #1718's Case 5 value-receiver bridge resolved correctly only because resolveDefGraphId happened to fall back to simpleKey after the qualified-key miss — accidental correctness. After this change, scope-resolution defs for `const x = ...` declarations report def.type === 'Const', matching the graph node label. resolveDefGraphId's qualified-key path now hits on the first try; the simple-key fallback is no longer load-bearing for value receivers and can be tightened in future without silently breaking Case 5. Audit completeness verification: - Grep `\bVariable\b` across src/core/ingestion/scope-resolution/ surfaced two consumer sites that already accept both labels: reconcile-ownership.ts:101+168 (`def.type === 'Variable' || def.type === 'Const' || ...`) and walkers.ts:207 isOwnableValueLabel (`Const | Variable | Property | Static`). No language hook in src/core/ingestion/languages/ branches on `def.type === 'Variable'` for what's actually a const declaration. - Sentinel stress test (the full unit + integration suite run with the renamed label in place): 6137/6137 unit tests pass; 2967/2967 integration tests pass. One pre-existing Windows-only flake on worker-pool.test.ts when run alongside the full integration suite (passes 28/28 in isolation, unrelated to scope-extractor — same flake observed before this diff). The variable mapping (`'variable' → 'Variable'`) is preserved for `var` declarations, matching the legacy DAG's `@definition.variable` capture for variable_declaration. The split now mirrors the parse-phase capture distinction exactly. Per plan docs/plans/2026-05-21-002-feat-pr1718-followups-class-instance-and-label-normalization-plan.md U4 + U5. T1 (class-instance singleton resolution from issue #1358's second sub-case) is deferred to a standalone pre-plan investigation, not shipped here. * test(ingestion): add regression coverage for issue #1358 singleton sub-cases Closes the remaining sub-cases of issue #1358 surfaced by PR #1718's adversarial review (Finding 4, NOTED): the class-instance singleton (`export const fooService = new FooService();`) and the factory-pattern singleton (`export const fooService = makeFooService();`). Pre-plan investigation (per docs/plans/2026-05-21-002 § "Pre-Plan Investigation Task (T1)") confirmed Outcome A for both patterns — they already resolve end-to-end through scope-resolution's `@type-binding.constructor` capture (languages/typescript/query.ts:489-511) + `propagateImportedReturnTypes` chain-follow (scope-resolution/passes/imported-return-types.ts:114) + receiver-bound Case 4 simple typeBinding lookup (receiver-bound-calls.ts:625). The mechanism was wired correctly before this session; the regression-net wasn't. This test pins the behavior: - Pattern 1: `caller → FooService.getUser` CALLS edge with confidence 0.85 and reason 'import-resolved' - Pattern 2: same edge shape via factory chain-follow (the `@type-binding.alias` capture for `const u = find()` style) Both assertions use exact `.toEqual([{...}])` shape pinning so a future regression that targets a phantom Method node, emits at lower confidence, or drops the cross-file import-resolved reason fails loudly. Verification: 5/5 pass, 127/127 in targeted regression sweep including object-literal-owner-resolution.test.ts, ast-helpers-object-literal- binding.test.ts, has-method.test.ts, and cross-file-binding.test.ts. No production code change. The class methods get a class-qualified node id (`Method:src/service.ts:FooService.getUser#1`) distinguishing them from same-name methods on other classes — distinct from the bare-name node id shape PR #1718's object-literal case uses. * test(resolvers): add class-instance + factory-pattern singleton coverage for TS/JS (issue #1358) Closes the remaining sub-cases of issue #1358 surfaced by PR #1718's adversarial review (Finding 4). PR #1718 fixed object-literal-shorthand singletons (`export const fooService = { getUser() {} }`); this commit adds parallel coverage for the two other singleton shapes that resolve through the existing scope-resolution chain: // Pattern 1 — class-instance singleton export class FooService { getUser(id) { ... } } export const fooService = new FooService(); // Pattern 2 — factory-pattern singleton export class FooService { getUser(id) { ... } } export function makeFooService() { return new FooService(); } export const fooService = makeFooService(); Pre-plan investigation (per local plan docs/plans/2026-05-21-002 § "Pre-Plan Investigation Task (T1)") confirmed Outcome A — both patterns already resolve end-to-end through: - `@type-binding.constructor` capture (languages/{typescript,javascript}/ query.ts) seeds `fooService → FooService` at parse time - `propagateImportedReturnTypes` (scope-resolution/passes/ imported-return-types.ts:114) mirrors the typeBinding cross-file - Receiver-bound Case 4 simple typeBinding lookup (scope-resolution/passes/receiver-bound-calls.ts:625) MRO-walks FooService and emits the CALLS edge to getUser Tests added per language × pattern (5 each, 10 total): - node existence (Class, Method, Function, Const, plus Function for the factory pattern's `makeFooService`) - HAS_METHOD edge from class to method (class-instance variant) - CALLS edge from caller to `getUser` with `targetFilePath: 'src/service.{ts,js}'`, `reason: 'import-resolved'`, `confidence: 0.85` — exact `.toEqual([{...}])` shape pinning so a regression that emits at lower confidence or drops the cross-file reason fails loudly Fixtures placed under the existing `test/fixtures/lang-resolution/` convention. Tests appended to `test/integration/resolvers/{typescript,javascript}.test.ts`, matching the in-file pattern of every other resolver scenario. Also supersedes and removes the standalone `test/integration/class-instance-and-factory-singleton-resolution.test.ts` introduced earlier in this PR session (`0df91b77`) — the proper home for language-resolver scenarios is the per-language resolver test file alongside similar fixtures (`javascript-self-this-resolution`, `javascript-cross-file`, `typescript-tsconfig-paths`, etc.). One canonical location for the scenario, not two. Verification: 10/10 new singleton tests pass; 297/297 full TS+JS resolver suite pass (no regression in any existing resolver test). * test(resolvers): gate TS/JS singleton tests behind scope-resolution parity (CI run 26223603426) The class-instance and factory-pattern singleton CALLS-edge resolution tests added in c8e573b rely on scope-resolution-only mechanisms (`@type-binding.constructor` capture + `propagateImportedReturnTypes` mirror + receiver-bound Case 4). The `scope-parity / typescript parity` and `scope-parity / javascript parity` CI jobs run with `REGISTRY_PRIMARY_TYPESCRIPT=0` / `REGISTRY_PRIMARY_JAVASCRIPT=0` and exercise the legacy DAG path, which has no cross-file constructor-derived typeBinding propagation. Verified by job 77202610819 (TS parity) and 77202610869 (JS parity) failing with: × resolves caller.fooService.getUser() to FooService.getUser via constructor-inferred typeBinding × resolves caller.fooService.getUser() through the factory chain to FooService.getUser Note: my local Windows shell-prefix env-var invocation did not propagate the flag into vitest workers correctly (the cpp parity gate's 47-skipped behavior masked the issue when I ran an ad-hoc comparison), so the empirical "both modes pass" finding I posted earlier was wrong. CI is the source of truth. Changes: - test/integration/resolvers/helpers.ts: add `typescript` and `javascript` entries to `LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES` for the 2 CALLS-edge resolution tests in each language. Node-existence and HAS_METHOD assertions are NOT excluded — those pass under legacy DAG (parser-level emission is intact). - test/integration/resolvers/typescript.test.ts: drop the `it` import from vitest; replace with `const it = createResolverParityIt('typescript');` shadow (matches the c/cpp/csharp/go pattern at the top of those files). - test/integration/resolvers/javascript.test.ts: same shadow with `createResolverParityIt('javascript')`. Verification: - Default mode (registry-primary): 297/297 TS+JS resolver tests pass. - Legacy DAG mode: the 4 listed singleton CALLS-edge tests will skip; all other singleton assertions (node existence + HAS_METHOD edge) continue to run and pass under both modes. --------- Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>

Addresses the two deferred PR-review findings plus the remaining test gap. #1 — Worker-path scanner false positives: the line scanner now tracks block- comment and string state across lines (advanceCsScanState), so a `namespace` / `using static` keyword at the start of a line inside a block comment, verbatim string (@"..."), or raw string literal ("""...""") is no longer mistaken for a declaration on the worker cache-miss path. It matches only at code-state line starts. 5 new scanner tests cover the block-comment / raw / verbatim cases. #4 — workspaceFqnBindings type safety: the ReadonlyMap->Map cast is localized to one documented line, and global-namespace writes go through a new getWorkspaceBucket helper (mirroring getAugmentationBucket) rather than an inline `.set()` at the mutation site. #2 — lookupBindingsAt workspace-channel coverage: walkers-augmentations.test.ts now exercises the third (workspace) channel: workspace-only, append-after- finalized/augmented, and dedup-loses-to-finalized/augmented precedence. #5 — OOM CI guard: the deterministic O(D) invariant (zero per-scope augmentation for global types) is already asserted by the always-on csharp-hooks unit tests added earlier; the scale/time benchmark stays appropriately opt-in (skipIf). Verified: tsc --noEmit clean; 69 unit tests (4 suites) + 210 C# integration resolver tests pass; prettier clean; eslint 0 errors. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

#1905) * fix(csharp): eliminate O(S·D) BindingRef OOM in namespace siblings Types declared in the C# global (default) namespace are visible from every file, so the previous per-scope augmentation materialized O(scopes × defs) BindingRefs — on large Unity solutions (tens of thousands of global types) this caused severe slowness and OOM. Route global-namespace types through a single workspace-level binding channel (workspaceFqnBindings, consulted by lookupBindingsAt) for O(D) memory. Also fix quadratic costs in the non-global path: append defs in place instead of copying (was O(D²) per bucket), pre-index the first scope per file (was O(S²·D)), and seed de-dup sets instead of repeated .some scans. Add csharp-pipeline-benchmark.test.ts (mirrors the PHP benchmark) with spread and concentrated-global-namespace scenarios to track elapsedMs, peakHeapMB, nodeCount, and edgeCount. Post-fix runs show linear scaling and stable heap. Co-authored-by: Cursor <cursoragent@cursor.com> * perf(csharp): scanner fallback for namespace siblings on the worker path Worker threads can't return tree-sitter Trees across MessageChannels, so the cross-phase tree cache is empty for worker-parsed files. The C# same-namespace pass (populateCsharpNamespaceSiblings -> extractFileStructure) then re-parsed every file with tree-sitter to find namespace / using-static nodes — effectively parsing a large solution a second time during scope resolution. Add a line-scanner fallback (extractCsharpStructureViaScanner) used only when no cached Tree is available, mirroring PHP's fix for issue #1741. It extracts the same namespaces / usingStaticPaths the AST walk produces for the common line-anchored forms (file-scoped + block namespaces, plain / global / aliased `using static`). The AST walk stays authoritative on the sequential / warm-cache path.

#1881) (#1908) * fix(csharp): eliminate O(S·D) BindingRef OOM in namespace siblings Types declared in the C# global (default) namespace are visible from every file, so the previous per-scope augmentation materialized O(scopes × defs) BindingRefs — on large Unity solutions (tens of thousands of global types) this caused severe slowness and OOM. Route global-namespace types through a single workspace-level binding channel (workspaceFqnBindings, consulted by lookupBindingsAt) for O(D) memory. Also fix quadratic costs in the non-global path: append defs in place instead of copying (was O(D²) per bucket), pre-index the first scope per file (was O(S²·D)), and seed de-dup sets instead of repeated .some scans. Add csharp-pipeline-benchmark.test.ts (mirrors the PHP benchmark) with spread and concentrated-global-namespace scenarios to track elapsedMs, peakHeapMB, nodeCount, and edgeCount. Post-fix runs show linear scaling and stable heap. Co-authored-by: Cursor <cursoragent@cursor.com> * perf(csharp): scanner fallback for namespace siblings on the worker path Worker threads can't return tree-sitter Trees across MessageChannels, so the cross-phase tree cache is empty for worker-parsed files. The C# same-namespace pass (populateCsharpNamespaceSiblings -> extractFileStructure) then re-parsed every file with tree-sitter to find namespace / using-static nodes — effectively parsing a large solution a second time during scope resolution. Add a line-scanner fallback (extractCsharpStructureViaScanner) used only when no cached Tree is available, mirroring PHP's fix for issue #1741. It extracts the same namespaces / usingStaticPaths the AST walk produces for the common line-anchored forms (file-scoped + block namespaces, plain / global / aliased `using static`). The AST walk stays authoritative on the sequential / warm-cache path.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(csharp): gate suffix-fallback import resolution to declared namespaces (#1881) C# `using` directives were resolving via an ungated suffix match, so a BCL using like `System.Threading.Tasks` matched a coincidental local `Tasks.cs` and emitted spurious IMPORTS edges. Add a declared-namespace gate that only permits suffix-fallback when the import plausibly refers to an in-repo namespace (exact, immediate-parent-declared, or ancestor-of a declared namespace anchored at an in-repo root). Both resolution legs — the legacy DAG and the registry-primary scope resolver — thread the same evidence to the gate, including the no-csproj path. Declared namespaces are collected with #1905's comment/string-aware scanner (extractCsharpStructureViaScanner, lazily imported) instead of a regex, so `namespace` tokens in comments/strings can't seed phantom namespaces. Scan truncation or unreadable subtrees fail OPEN (gate disabled) and are logged. Stacked on #1905 (fix/csharp-namespace-scope-oom). Co-authored-by: Cursor <cursoragent@cursor.com> * fix(csharp): cap per-file size in namespace scan; fail open on skip (#1881) scanCSharpProject read every .cs/.csproj in full with no size guard and issued per-directory reads with no concurrency bound, an OOM/FD-exhaustion vector on large or generated repos. Add an fs.stat size guard before each read, reusing getMaxFileSizeBytes() (the same 512KB cap the Phase-1 walker uses). An oversized or unreadable .cs now signals truncation so the #1881 suffix-fallback gate fails OPEN rather than wrongly suppressing an import whose declaring namespace lived in the skipped file (previously a silent return left the scan looking complete). Adds a size-cap scan test. * fix(csharp): bound per-directory read concurrency in namespace scan (#1881) The scan issued every .cs/.csproj read in a directory at once via Promise.all, so in-flight file descriptors scaled with the largest directory's file count. Issue reads in bounded windows (32, mirroring the Phase-1 filesystem-walker) via Promise.allSettled; an unexpected read/scan rejection now trips truncation (fail open) instead of rejecting the whole scan. Behavior-preserving for namespace collection (C# scope-resolution parity passes on both legs). * style(csharp): apply prettier to #1881 files to clear quality/format gate (#1908) Reflow hand-wrapped lines in scope-resolver.ts and the csharp integration test that prettier collapses under printWidth 100. Formatting only, no behavioral change; clears the failing quality/format CI gate. * fix(csharp): stream namespace scan so large generated files don't disable the #1881 gate (#1908) Code-review follow-up. The scan read each .cs fully into a string behind a 512KB size cap (the tree-sitter parse budget); a single larger generated file (*.g.cs, EF/gRPC output) tripped `truncated`, making the #1881 suffix-fallback gate fail open repo-wide and silently undoing the fix on real repos. Stream each .cs line-by-line via createReadStream + readline into a new incremental scanner (createCsharpStructureScanner) instead of buffering the whole file. Memory is now constant regardless of file size, so the per-file size cap is dropped for the namespace line-scan and large generated files are fully collected. extractCsharpStructureViaScanner is reimplemented on the same incremental scanner (byte-identical; C# parity 2/2). collectDeclaredNamespaces returns 'ok' | 'truncated' (truncation now only from an unreadable file) and the truncation warn lists its real causes. csproj reads keep their size guard. Prior art: ripgrep/ctags/Node readline stream rather than cap for line scans; GitHub (384KB) and Sourcegraph (1MB) cap only their full-content indexes. * fix(csharp): cap .csproj read via stream, not stat-then-read, to clear CodeQL TOCTOU (#1908) CodeQL js/file-system-race flagged the fs.stat + fs.readFile size guard in readCsprojConfig as a check-then-use filesystem race. Replace it with a length-capped createReadStream (readFileTextCapped) — same memory bound on untrusted input, no stat-then-read race, and consistent with the streamed .cs scan. Behavior is unchanged for real .csproj files (parity 2/2). * fix(csharp): keep BCL/external roots gated through scan truncation (#1908, Codex F1) A single scan truncation (unreadable dir/file, depth/dir cap) set one repo-wide `truncated` flag that made csharpSuffixFallbackAllowed fail open for EVERY import, silently re-enabling the #1881 BCL->local suffix matches. Add a CSHARP_EXTERNAL_ROOTS denylist (System/Microsoft/...): an external-rooted using that does not align with an in-repo declared namespace stays BLOCKED even under truncation, while genuinely local-looking usings still fail open. A repo that declares the root is allowed via the alignment escape hatch. Shared predicate, so both legs inherit it. * fix(csharp): gate the registry no-csproj direct-match path (#1908, Codex F2) In the no-csproj branch of resolveCsharpImportTarget, resolveDirectMatch ran BEFORE the gate, so a path-aligned Legacy/System/Threading/Tasks.cs satisfied 'using System.Threading.Tasks;' even though System.* is not a declared in-repo namespace — while the legacy leg (gate-first) blocked it, so the legs were not equivalent. Run csharpSuffixFallbackAllowed first (return null on fail), then direct-match, then progressive stripping — mirroring the legacy ordering. Adds a no-csproj fixture with a deep path-aligned Tasks.cs and dual-leg integration describes (registry + forced-legacy), plus a path-aligned unit case. Parity 2/2. * fix(csharp): flag scanner-uncaptured namespaces incomplete; Unicode/@ matchers (#1908, Codex F3) The line scanner treated its output as complete even when it missed valid C# namespace forms, so the gate failed CLOSED and over-blocked legit imports. Make CS_NAMESPACE_RE/CS_USING_STATIC_RE Unicode-aware (\p{L}\p{N} + u flag) and strip leading/segment @ so verbatim/Unicode identifiers are captured to match the AST. For forms the regex still can't capture (split across lines, not at line start, attributed), set a per-file 'incomplete' flag; collectDeclaredNamespaces returns 'truncated' for such files so the #1881 gate fails OPEN instead of dropping the namespace. High-precision detectors + guard tests keep ordinary forms (incl. // namespace comments) from tripping incomplete. * fix(csharp): stream the .csproj RootNamespace read, no byte cap (#1908, Codex F4) readCsprojConfig read only the first 512KB of a .csproj and, on a match-miss, couldn't tell 'no RootNamespace' from 'RootNamespace past the cap' — both synthesized a filename root. A wrong authoritative root makes imports under the real root resolve to nothing AND suppresses the fallback. Replace the capped read with a streamed early-stop search (findCsprojRootNamespace) that reads until the tag or EOF: filename fallback ONLY on genuine read-to-EOF absence; on a soft-budget cap-hit or unreadable file, OMIT the config so the no-csproj fallback stays reachable. Removes the now-unused readFileTextCapped + getMaxFileSizeBytes cap from the scan. Parity 2/2. --------- Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

) * chore: extend .gitattributes for shell scripts and binary assets Append explicit `*.sh text eol=lf` and `*.bash text eol=lf` rules so shell scripts (notably anything COPYed into a Linux container) check out with LF endings on Windows hosts with `core.autocrlf=true`, regardless of the auto-detection on the existing `* text=auto eol=lf` line. Add binary markers for `*.node`, `*.wasm`, `*.onnx`, `*.so`, `*.dll`, `*.dylib` so native and ML model artifacts aren't ever subjected to text normalization. The existing `* text=auto eol=lf` and `.husky/* text eol=lf` rules are preserved. `git ls-files --eol` confirmed zero CRLF or mixed blobs in the index, so no `--renormalize` was needed. * feat(devcontainer): add cross-platform devcontainer for Claude Code, Codex, and Cursor CLIs Add a Dev Container that pre-installs Claude Code (2.1.153, via Anthropic's official Feature), OpenAI Codex CLI (pinned 0.134.0), and Cursor CLI alongside the GitNexus native build chain. Opens via VS Code's Dev Containers extension on Windows 11 (Docker Desktop + WSL2), macOS, or Linux without OS-specific branches in devcontainer.json. Topology and base - Base image `mcr.microsoft.com/devcontainers/typescript-node:1-22-bookworm` (multi-arch, monthly patched, ships the `node` non-root user, zsh, `gh`). - Node 22 LTS satisfies `gitnexus/`'s engines `>=22.0.0` and matches the `node:22-bookworm-slim` SHA-pinned base used by `Dockerfile.cli`. - Single container with all three CLIs co-installed (vs. docker-compose per-tool) — prevailing 2026 community pattern, lowest daily-driver friction. Persistence and auth - Per-devcontainer named volumes scoped by `${devcontainerId}` for `/home/node/.claude`, `/home/node/.codex`, `/home/node/.cursor`, `/commandhistory`, and `/home/node/.npm`. Authentication survives rebuilds without leaking between workspaces. - Four sub-workspace `node_modules` volumes (root, gitnexus, gitnexus-web, gitnexus-shared) keep tree-sitter native bindings and onnxruntime off the bind mount — the actual Win/Mac perf win. - Credential mount paths are pre-created in the Dockerfile with `chown node:node` BEFORE `USER node`, so empty named volumes inherit correct ownership on first mount and first-run logins don't EACCES. - `CURSOR_API_KEY` is injected via `containerEnv: ${localEnv:CURSOR_API_KEY}` (Cursor's documented headless path); falls back to interactive `cursor-agent login` when the host env var is unset. Build-arg promotion - Build args (`CLAUDE_CODE_VERSION`, `CODEX_VERSION`, `CURSOR_VERSION`, `TZ`) are promoted to ENV in the Dockerfile so lifecycle commands and shells can resolve them. Without this promotion, Docker ARG values are build-only and silently no-op at lifecycle time. Workspace setup - `postCreateCommand` chowns the four workspace `node_modules` volumes (Docker creates them root-owned), then installs in dependency order: root → gitnexus-shared (install + build) → gitnexus → gitnexus-web. The shared package must build before its consumers (`file:../gitnexus-shared`). Ports - 5173 (Vite dev) and 4173 (Vite preview) auto-forwarded. - 4747 (`gitnexus serve`) marked `requireLocalPort: true` because `gitnexus-web/src/services/backend-client.ts` hardcodes `http://localhost:4747` as the default backend URL; a remapped port would silently break the web UI. VS Code integration - Recommended extensions: `anthropic.claude-code`, `dbaeumer.vscode-eslint`, `esbenp.prettier-vscode`, `eamodio.gitlens`. - Settings: format-on-save with Prettier, ESLint auto-fix on save, zsh as default terminal profile, persistent zsh history via `HISTFILE` → `/commandhistory`. Documentation - `.devcontainer/README.md` covers WSL2 setup (clone inside WSL2 for IO and file-watcher reliability), first-time auth flows for each CLI, port- forwarding notes, LadybugDB container limitations, and the bumping procedure for each CLI version. - `CONTRIBUTING.md` gets a "Containerized development (optional)" subsection pointing at the devcontainer README. Deferred to a follow-up PR - Opt-in egress firewall (originally planned as a fourth implementation unit). The Dev Containers spec makes `runArgs` static — toggling `NET_ADMIN`/`NET_RAW` capabilities cleanly requires either a separate `devcontainer-firewall.json` profile or an `initializeCommand`-generated overlay. Keeping this PR focused on the working baseline. - Codespaces-specific tuning (works incidentally when the firewall is off, not actively tested). - Inside-container Playwright e2e (needs Chromium libs not in the base image). Verification deferred to user - This change introduces a new dev tooling artifact. Validate by running `docker build .devcontainer/`, opening the repo in VS Code via "Dev Containers: Reopen in Container", confirming `claude --version`, `codex --version`, `cursor-agent --version` resolve inside the container, and `cd gitnexus && npm run test:unit` runs clean against the named-volume `node_modules`. * fix(devcontainer): make interactive login the default auth path for all CLIs The previous `containerEnv` injected `CURSOR_API_KEY: "${localEnv:CURSOR_API_KEY}"`. When the host had no `CURSOR_API_KEY` set, this resolved to an empty string and Docker injected `CURSOR_API_KEY=""` into the container. Cursor CLI treats a set-but-empty `CURSOR_API_KEY` as "use this key" rather than "fall back to stored login", which silently broke `cursor-agent login` on the most common path — users who hadn't explicitly opted into API key auth. Drop `CURSOR_API_KEY` from `containerEnv`. Login is now the unconditional default for all three CLIs (Claude Code, Codex CLI, Cursor CLI); the named-volume + Dockerfile-chown pattern keeps credentials persistent across container rebuilds for every login path. Reorganize the README's auth section to put login first for all three CLIs uniformly (matching the new behavior) and move API key authentication into a separate "Alternative" section for CI/headless use. Document that API keys are intentionally not auto-propagated from the host and explain the export-in-shell or VS Code dotfiles-repo paths for users who want them. Update the troubleshooting row to reflect the new design. * fix(devcontainer): install gitnexus-web before gitnexus in postCreateCommand The previous order (root → gitnexus-shared → gitnexus → gitnexus-web) broke at the `gitnexus` install step because `gitnexus`'s `prepare` script runs `scripts/build.js`, which compiles `gitnexus-web` whenever its source tree exists. In the devcontainer the entire workspace is bind-mounted, so `gitnexus-web/` is present from the start — but its `node_modules/` wasn't yet, so `tsc -b` failed with: error TS2688: Cannot find type definition file for 'vite/client' error TS2688: Cannot find type definition file for 'node' Reorder so `gitnexus-web` installs before `gitnexus`. Verified end-to-end via `npx @devcontainers/cli up`: container builds clean, all three CLIs (Claude 2.1.153, Codex 0.134.0, Cursor) respond, and `npx tsc --noEmit` inside `/workspace/gitnexus` passes. Production Dockerfiles (`Dockerfile.cli` etc.) don't hit this because they only COPY `gitnexus/` + `gitnexus-shared/`, so `gitnexus-web/` doesn't exist at install time and `scripts/build.js` skips the web step. The devcontainer's full-tree bind mount changes that calculus. * fix(devcontainer): clear stale .husky/_ before npm install When `npm install` runs the root `prepare` script (husky), husky tries to copyfile `node_modules/husky/husky` → `.husky/_/h`. On Docker Desktop Windows bind mounts, if `.husky/_/` already exists from a prior container run, the new container's `node` user can't overwrite it via the bind mount's permission translation and the install fails with: Error: EPERM: operation not permitted, copyfile '/workspace/node_modules/husky/husky' -> '.husky/_/h' Drop `.husky/_` defensively in `postCreateCommand` before `npm install` so husky always starts from a clean slate. `.husky/_` is a husky runtime cache (gitignored), so removing it has no effect on the repo — husky regenerates it. No-op for WSL2-side checkouts (where this class of bind-mount permission collision doesn't occur). Add a troubleshooting row to `.devcontainer/README.md` covering the manual recovery (`rm -rf .husky/_` on the host) and the long-term fix (clone in WSL2 — Windows-side bind mounts will keep biting on this kind of issue across rebuilds with different UID alignment). * feat(devcontainer): bind-mount host CLI config dirs for plugin/skill/memory sync Switch the credential/config mounts from per-devcontainer named volumes to bind mounts of `${localEnv:HOME}/.claude`, `~/.codex`, and `~/.cursor`. Effect inside the container: - Authentication is shared with the host. If you've already run `claude login` / `codex login --device-auth` / `cursor-agent login` on the host, you're already authenticated in the container. - Plugins, skills, agents, memory, and settings sync both ways. Install a plugin in the container, it shows up on the host; add a custom agent on the host, the container sees it immediately. - All devcontainers on the host share the same CLI state, mirroring how host shells already share it. (Per-workspace isolation of plugins was never a stated requirement; the previous per-devcontainer named volumes leaked nothing useful.) Add `.devcontainer/ensure-host-config-dirs.cjs` and wire it as `initializeCommand`. It runs on the host before container create and guarantees `~/.claude`, `~/.codex`, `~/.cursor` exist, so Docker doesn't reject the bind mount when a CLI has never been used on this host. Cross-platform via Node `os.homedir()` + `fs.mkdirSync({recursive: true})`; idempotent; no third-party deps. Update `.devcontainer/README.md`: - New "How CLI state is shared with your host" section explaining the bind-mount model up front so users know their host plugins/skills/ memory carry into the container. - Mark first-time-login section as skippable when the user is already authenticated on the host. - Note the high-trust escape hatch: replace the three bind mounts with `type=volume` named volumes if the host/container trust boundary needs to be separated (Anthropic's reference pattern for enterprise). - Replace the obsolete "rm named volume" troubleshooting row with one that covers EACCES/EPERM on the host-bind-mount path. * refactor(devcontainer): address ce-code-review findings (P0 + 4 × P1 + 8 × P2 + 2 × P3) Walkthrough resolution of the 16-finding ce-code-review on PR #1875. 15 of 16 findings applied; one (F12, Anthropic Feature floating tag) was superseded by F6's Feature removal. P0 - F1: WSL2 is now REQUIRED for Windows hosts, not just recommended. ${localEnv:HOME} resolves to empty string on Windows-native (no HOME env var) — bind mounts then point at /.claude, /.codex etc. and silently break. ensure-host-config-dirs.cjs wrote to USERPROFILE-derived paths via os.homedir(), so the two surfaces disagreed about which env var was "home" on Windows. README header reframed; "Windows 11 — WSL2 is required" section explains the mismatch concretely. P1 - F2: Workspace `node_modules` volume names now include `-${devcontainerId}` so two GitNexus checkouts on the same host (~/work/GitNexus and ~/projects/GitNexus) don't share volumes and corrupt each other's installs. - F3 + F5: `postCreateCommand` extracted to `.devcontainer/post-create.sh` with `set -euo pipefail` and six labeled echo steps so failure logs name the step instead of an opaque &&-chain index. Chown step extended to cover /home/node/.npm, /commandhistory, and /home/node/.local — these named-volume mount points were owned by build-time UID 1000 but the container's `node` is re-IDed at runtime by updateRemoteUserUID on non-1000 Linux hosts, leaving them unwritable until now. - F4: Cursor installer downloaded to a temp file with curl --retry + --max-time; sha256 logged to build output before execution so drift across rebuilds is visible in CI logs. Full hard-pin (to a versioned downloads.cursor.com tarball with verified sha256) tracked as a follow-up in README "What's not included". P2 - F6: Anthropic Feature replaced with a direct `npm install -g @anthropic-ai/claude-code@${CLAUDE_CODE_VERSION}` so CLAUDE_CODE_VERSION actually pins the installed binary (the Feature ignored the ARG and pulled latest at install time). Honors the earlier "pin known-good versions" decision and resolves F12's floating-tag concern for this Feature. - F7: Dockerfile ARG defaults dropped for the three version vars; `devcontainer.json` `build.args` is now the single source of truth. Standalone `docker build .devcontainer/` must pass --build-arg. - F8: ensure-host-config-dirs.cjs deleted; `initializeCommand` now uses POSIX `mkdir -p` + `touch ~/.gitconfig` directly, dropping the host-Node-on-PATH prerequisite that broke on fresh Windows+Docker Desktop installs without Node. - F9: ~/.gitconfig bind-mounted read-only so `git commit` inside the container uses the host's user.name / user.email. Read-only so container-side `git config --global` doesn't leak to host. - F10: ~/.config/gh bind-mounted (read-write) so `gh pr create` / `gh pr checks` / `gh issue create` work inside the container without re-auth. AGENTS.md's commit + PR workflow now fully functional for agents inside the container. - F11: CLAUDE_CONFIG_DIR removed from Dockerfile ENV; canonical value lives only in devcontainer.json containerEnv. Eliminates the two-file edit risk. - F13: Mounts comment now documents per-instance vs per-workspace-name scoping rationale so future contributors don't guess. - F14: README "Trust boundary, concretely" paragraph names the exfil path explicitly (malicious npm postinstall → OAuth tokens → ~/.claude/projects/<workspace>/memory/MEMORY.md secrets) and lists vendor-side rotation runbook entries. P3 - F15: Dockerfile pre-create + chown of /home/node/.claude, .codex, .cursor dropped — those paths are bind-mounted, which fully shadows any image-side ownership. Only .npm, .local, /commandhistory still benefit from the pre-create. - F16: README "Bumping CLI versions" section rewritten against the post-F6 reality: CLAUDE_CODE_VERSION and CODEX_VERSION are real pins; CURSOR_VERSION is informational only. Verified locally: `docker build .devcontainer/ --build-arg ...` succeeds. Smoke-tested image: `claude --version` (2.1.153), `codex --version` (0.134.0), `cursor-agent --version` all resolve as the non-root `node` user; named-volume mount points (/home/node/.npm, /commandhistory) are node-owned at build time so non-1000 host UIDs get the post-create.sh chown fix instead of EACCES. * fix(devcontainer): cross-platform initializeCommand + soften Windows-native posture The previous commit's `initializeCommand` was POSIX-only (`mkdir -p $HOME/...`). VS Code on Windows runs the host shell as `cmd.exe /c ...`, which can't parse POSIX syntax — `$HOME` doesn't expand, `mkdir -p` errors, the init fails with `The syntax of the command is incorrect`, and container creation aborts before Docker is invoked. Switch `initializeCommand` to the spec's OS-keyed object form: - linux/darwin (covers WSL2 because VS Code runs initializeCommand in the WSL shell when attached via the WSL extension): POSIX mkdir+touch, as before - win32: PowerShell snippet that creates the same directories under $USERPROFILE and touches the gitconfig if missing Soften the README's hard "WSL2 required" framing from the previous commit. Reality per `@devcontainers/cli read-configuration` output: `${localEnv:HOME}` on Windows-native resolves to `C:\Users\<name>` (VS Code falls back to USERPROFILE), so the bind mount sources are valid Windows paths and Docker Desktop handles the translation. The earlier `accessing specified distro mount service` failure was a separate Docker Desktop WSL-integration issue, not a HOME-resolution issue. Windows-native works; it's just slower with more bind-mount permission edge cases (the husky/_/h EPERM class). The README now explains the tradeoff and steers toward WSL2 for performance + file watchers + permission reliability, rather than blocking Windows-native checkouts outright. Update the troubleshooting row to reflect the new posture. * fix(devcontainer): Node-based initializeCommand; bind-mount .ssh + .config/git Two fixes bundled: 1. The previous commit's OS-keyed `initializeCommand` object was based on a misread of the Dev Containers spec. The object form on command properties is **named parallel tasks**, not OS dispatch — VS Code ran all three keys in parallel via cmd.exe on Windows, the POSIX branches failed, and container creation aborted before Docker was invoked. Restore the single-string Node-based form: `node .devcontainer/ensure-host-config-dirs.cjs`. Node works identically in cmd.exe on Windows and bash/zsh on Linux/macOS/WSL, and `os.homedir()` respects $HOME on POSIX and %USERPROFILE% on Windows. The script is idempotent (mkdirSync recursive is a no-op for existing dirs; touch is gated on .gitconfig existence). Document Node ≥18 on the host as the only host-side prerequisite beyond Docker Desktop and the VS Code Dev Containers extension. Anyone running Claude Code on the host already has it. 2. Extend the host-bind mount surface with `~/.ssh` and `~/.config/git`, both read-only: - `~/.ssh` lets commit signing + push over SSH remotes work inside the container without copying private keys. Read-only mount means container code can read keys but can't modify or delete them. (Threat: a malicious dep can still read private keys from inside the container; the read-only mount narrows write-side blast radius, not read-side. Documented in the trust-boundary section.) - `~/.config/git` covers XDG-style git config (`~/.config/git/config`, `~/.config/git/ignore`, `~/.config/git/attributes`) for users who keep settings there instead of `~/.gitconfig`. Read-only, same as `~/.gitconfig`. Update the CLI-state-sharing table and trust-boundary paragraph to reflect the expanded surface. Re-adds .devcontainer/ensure-host-config-dirs.cjs (deleted before the OS-keyed attempt). * fix(devcontainer): fail-fast on Windows-native with HOME-not-set diagnostic The previous commit's "Windows-native works" softening was wrong. VS Code on Windows-native resolves `${localEnv:HOME}` by reading the host shell's HOME env var, and cmd.exe has no HOME set — the bind sources collapse to `/.claude`, `/.codex`, etc., and Docker errors: Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /.claude The @devcontainers/cli output that prompted the softening was misleading because I ran it from a Bash session with HOME already set, not from VS Code's cmd.exe call context. The original Finding-1 P0 — that Windows- native silently breaks the bind-mount feature — was correct. Three changes: 1. `ensure-host-config-dirs.cjs` detects the failure mode early: `if (process.platform === 'win32' && !process.env.HOME)` prints a targeted error message naming the root cause (cmd.exe has no HOME → ${localEnv:HOME} resolves empty → bind sources fail) and a step-by-step pointer to set up WSL2. Exits 1 so VS Code surfaces it as a clean container-creation failure, not the cryptic Docker bind-mount error. 2. README header reverted to "Windows 11 via WSL2" only (not "and Windows-native"). The "Windows 11 — WSL2 is required" section names the specific HOME-resolution mismatch concretely so future readers understand why the constraint exists. 3. Troubleshooting table gets a new row for the `ERROR: GitNexus devcontainer requires WSL2` message pointing at the setup section. * feat(devcontainer): support Windows-native via auto setx HOME on first run Reverses the "WSL2 required on Windows" posture. Windows-native now works after a one-time auto-handled setup. The root cause of the bind-mount failure: VS Code resolves `${localEnv:HOME}` by reading its own process env, and Windows doesn't set `HOME` by default — Windows uses `USERPROFILE`. So the bind sources were collapsing to `/.claude`, `/.codex`, etc., and Docker rejected them. `ensure-host-config-dirs.cjs` now handles this automatically on Windows hosts where `HOME` is unset: 1. Runs `setx HOME "%USERPROFILE%"`, which writes to the user-level Windows environment (HKCU\Environment) — no admin required. Every future user process inherits HOME from there. 2. Prints a clear one-time setup banner explaining the user needs to fully restart VS Code (File > Exit, not just close the window) for VS Code to pick up the new env at its next startup. 3. Exits 1 so VS Code surfaces this as a clean container-create failure instead of letting Docker error opaquely later. On the second Reopen-in-Container attempt, `HOME` is now set in VS Code's env, the script skips the setup block, creates the bind-mount source dirs, and the container builds normally. Subsequent rebuilds have no extra steps. Mac, Linux, and WSL2 hosts have `HOME` set by the shell, so the new block is a no-op there. Same `devcontainer.json` works across all supported hosts. README rewritten to reflect the new posture: - Header lists Windows 11 (native) as a supported host alongside macOS, Linux, and WSL2, with a note that Windows-native gets a one-time HOME setup handled by the initializeCommand. - New "Windows 11 setup" section walks through the auto-handled setup flow + a manual `setx HOME "%USERPROFILE%"` fallback for users who want to do it themselves. - "Known trade-offs of Windows-native vs WSL2" subsection lays out the Docker Desktop Windows bind-mount edge cases (file watchers, npm install perf, husky/_ EPERM) so users opting into Windows-native do so eyes-open. WSL2 remains documented as the faster path for users who want it, but it's no longer the only supported one. - Troubleshooting table gets two new rows: the one-time setup banner (with "what to do" instructions) and the residual `bind source path does not exist` case (run setx manually + fully exit VS Code). * fix(devcontainer): drop ~/.gitconfig bind mount; defer to VS Code auto-copy VS Code's Dev Containers extension auto-copies the host's gitconfig into the container at attach time using `(dd ...) >> /home/node/.gitconfig`. A read-only bind mount of ~/.gitconfig blocks that write, so attach failed with `cannot create /home/node/.gitconfig: Read-only file system`. Making it read-write would let the append succeed, but the bind mount means the host file and the container file are the same file — VS Code's append would double the host gitconfig contents on every container start. Drop the ~/.gitconfig bind mount entirely. VS Code's auto-copy is the purpose-built mechanism for this, gives the container the host's user.name / user.email transparently, and avoids both the read-only write failure and the append-duplication trap. The container ends up with a writable /home/node/.gitconfig that's a copy of the host's, not a mount. The remaining six bind mounts (.claude, .codex, .cursor, .ssh, .config/git, .config/gh) keep their existing modes — XDG-style git config under ~/.config/git is unaffected by VS Code's auto-copy (which only targets ~/.gitconfig), so its read-only bind mount stays. Also remove the `.gitconfig` touch from ensure-host-config-dirs.cjs (now unnecessary) and update the README CLI-state table, sharing explanation, and troubleshooting row to reflect that gitconfig flows in via VS Code auto-copy rather than the bind mount. * feat(devcontainer): bind-mount ~/.docker, ~/.aws, ~/.azure for agent workflows Extend the host bind-mount surface so coding agents inside the container inherit cloud + container-registry auth from the host without any per-container setup: - ~/.docker (read-write) — Docker registry auth (config.json) + buildx config. Container-registry pushes (ghcr.io, docker.io) from inside the container pick up host `docker login` state. Read-write because the Docker CLI refreshes credential-helper tokens. - ~/.aws (read-only) — AWS CLI / SDK credentials. Read-only because rotating creds typically happens via the host. Empty on this dev box, so forward-compatible: the moment you `aws configure` on the host the container picks it up on the next rebuild. - ~/.azure (read-only) — Azure CLI credentials. Same pattern as ~/.aws. `ensure-host-config-dirs.cjs` extends to mkdir these three on init so the bind mounts always have a valid source even if a CLI has never been used on this host. The Docker CLI itself isn't installed in the container by default — the ~/.docker/ mount is inert until you add `docker-outside-of-docker:1` or similar Feature. README now calls this out under "What you still don't have inside the container" so it's obvious which CLIs are agent-ready and which need a feature add to become useful. README updates: - Bind-mount table gains a "Why" column and rows for the three new mounts, making it clear at a glance what each one enables. - Trust-boundary section lists Docker registry tokens, AWS, and Azure creds in the read-side exfil path so the threat model stays honest as the credential surface grows. - New subsection lists not-included CLIs (Docker, AWS, Azure, gcloud, kubectl, private-npm) with the exact Feature ID or mount snippet needed to enable each — turns "I want my agent to do X" into a one-line config change. Verified locally: `npx @devcontainers/cli read-configuration` resolves all 9 host bind mounts to valid C:\Users\<name>/* paths on Windows. * refactor(devcontainer): hybrid AI CLI config — read-only host share + per-container credentials Restructure the Claude Code / Codex / Cursor mount topology to fix the silent first-run-UI bug surfaced in PR testing, and to harden against the host-write-through escape class the previous bind-mount design exposed. The actual root cause of the first-run wizard firing on the user's screenshot — confirmed via three parallel research agents (best practices, framework docs deep dive of the OpenAI Codex Rust source, adversarial design review) — was NOT a credential permission check. Claude Code splits state across `~/.claude/.credentials.json` AND `~/.claude.json` (a FILE at $HOME, sibling of the `.claude/` dir). The latter holds `hasCompletedOnboarding`, `userID`, `oauthAccount` metadata, MCP user-scope config, and per-project trust state — and Claude Code reads it at literal `$HOME/.claude.json`, not via `CLAUDE_CONFIG_DIR`. The previous design mounted `~/.claude/` but left `~/.claude.json` outside the topology entirely, so every container started with a missing onboarding-state file and re-ran the wizard. Confirmed by tfvchow/field-notes-public#10: "Persisting .credentials.json alone is NOT sufficient. Without .claude.json, Claude Code treats the session as a fresh install and prompts for login regardless of valid credentials being present." The new topology: **Mounts** - `${localEnv:HOME}/.claude` → `/host/.claude` (read-only bind) - `${localEnv:HOME}/.codex` → `/host/.codex` (read-only bind) - `${localEnv:HOME}/.cursor` → `/host/.cursor` (read-only bind) - `${localEnv:HOME}/.claude.json` → `/host/.claude.json` (read-only bind) - `claude-config-${devcontainerId}` → `/home/node/.claude` (named volume) - `codex-config-${devcontainerId}` → `/home/node/.codex` (named volume) - `cursor-config-${devcontainerId}` → `/home/node/.cursor` (named volume) **containerEnv** gains `CODEX_HOME=/home/node/.codex` (Codex's own env override, per its public Rust source). `CLAUDE_CONFIG_DIR=/home/node/ .claude` was already set. **`post-create.sh`** stages the named volumes on first run: - Symlinks shareable subdirs from `/host/.claude` into the named volume: `plugins/`, `skills/`, `agents/`, `memory/`, `commands/`. Codex gets `config.toml` symlinked. Cursor has no shareable subdirs (cli-config .json conflates auth and settings). - Copies `.credentials.json`, `auth.json`, `cli-config.json` on first run with `chmod 600`. After first run, container manages its own refresh; host's credentials untouched. - Copies `~/.claude.json` on first run (with stub `{"hasCompletedOnboarding":true,"installMethod":"global"}` fallback for hosts that haven't run Claude Code). This is the fix for the observed onboarding-wizard loop. `ensure-host-config-dirs.cjs` now also touches `~/.claude.json` on the host if missing, so the bind mount has a valid source on hosts that have never run Claude Code. **Why read-only + named volume vs. the previous full bidirectional bind mount:** 1. **Host filesystem write-through escape, eliminated.** Previous design symlinked `plugins/`, `agents/`, `skills/` write-through into the host's `~/.claude/` — a malicious npm package in the workspace dep tree could drop `agents/evil.md` into the host's config, which the next host Claude session would auto-load. The read-only `/host` mount blocks this; container compromise no longer persists across teardown via host-side autoload. 2. **Windows bind-mount perm-flattening, sidestepped.** Files surfaced through a Docker Desktop Windows bind mount appear as `root:root` mode `777`. Credentials in the named volume come with proper Linux ownership and `chmod 600` — what each CLI expects on write (none enforces on read, but write-side hygiene matters for the host's understanding of "where credentials live"). 3. **No `ide/` lock-file collisions.** Previous design symlinked `~/.claude/ide/` write-through, including per-PID lock files. Host PID and container PID namespaces are unrelated → lock-file PIDs misclassify dead processes as alive. Skipping `ide/` keeps lock files container-local. 4. **No `projects/` ghost dirs.** Host encodes the workspace path as `D--development-coding-GitNexus`, container as `-workspace`. Bidirectional `projects/` symlinks would split memory and session state across two ghost project dirs for what is conceptually the same project. Skipping `projects/` keeps per-project state container-local; host's projects/ stays untouched. 5. **No `settings.json` version drift.** Container is pinned to a specific Claude Code version (`CLAUDE_CODE_VERSION` build arg); host floats with auto-update. Bidirectional `settings.json` writes produced silent schema rollback. Skipping settings.json keeps each side authoritative for its own version. **README** rewritten in the same section to describe the new topology honestly: what's shared, what isn't, the OAuth refresh-token divergence between host and container, per-CLI quirks (macOS Keychain storage, Cursor's known upstream in-container auth bug, Codex keyring storage). Trust-boundary section updated to name the threat model accurately — same read surface as before (malicious dep can still READ all credentials), but write-through into host plugin/agent dirs is now blocked. Verified locally: `@devcontainers/cli read-configuration` resolves all 19 mounts correctly on Windows, `post-create.sh` parses, and `ensure-host-config-dirs.cjs` idempotently touches `~/.claude.json`. Research backing this design: - Anthropic Claude Code devcontainer docs (named-volume pattern): https://code.claude.com/docs/en/devcontainer - tfvchow/field-notes-public#10 (both files required): https://github.com/tfvchow/field-notes-public/issues/10 - anthropics/claude-code#29029 (VS Code extension strips hasCompletedOnboarding): https://github.com/anthropics/claude-code/issues/29029 - OpenAI Codex Rust source (no read-side perm check): https://github.com/openai/codex/blob/main/codex-rs/login/src/auth/storage.rs - Cursor CLI in-Docker auth issue: https://forum.cursor.com/t/cursor-agent-authentication-issue-inside-docker/143995 * fix(devcontainer): resync AI CLI state from host on every container-create Two bugs were causing Claude Code to fire the onboarding wizard inside the container even with valid host credentials: 1. Missing the second state file. Claude Code 2.1.x writes a small `.claude.json` INSIDE `CLAUDE_CONFIG_DIR` (carrying migration tracking + userID), not just the one at `$HOME/.claude.json`. If the userIDs in the two files disagree, Claude treats the session as inconsistent and re-onboards. The previous post-create.sh only copied the `$HOME` one. 2. First-run guards (`[ ! -e $dst ]`) skipped the copy when stale named volumes from earlier rebuilds still had the prior session's state in them, leaving the container desynced from the host. Replace `copy_on_first_run` with `sync_from_host` that always overwrites from host on container-create. `link_readonly_share` now clears stale non-symlink dst entries before linking. Copies both `$HOME/.claude.json` and `$CLAUDE_CONFIG_DIR/.claude.json` so userIDs stay aligned. Container can still mutate its own state between rebuilds; resync only happens on rebuild (postCreate boundary). * docs(devcontainer): document sync-from-host design + dual-source auth flow README still described the old "first-run copy" behavior. After the post-create.sh change to always-sync-from-host, the design works either direction: - Log in on host → next container-create syncs the credentials into the named volume. - Log in inside the container → the named volume persists the login across rebuilds; the host has no source to overwrite from, so it stays alone. Also documents the two-Claude-state-files trap (`$HOME/.claude.json` AND `$CLAUDE_CONFIG_DIR/.claude.json`, both with the same userID required), and the volume-deletion recovery path for stale named volumes carried over from earlier rebuilds. * fix(devcontainer): full plugin/config parity by dropping CLAUDE_CONFIG_DIR + syncing settings.json Two changes that together give the container the same plugins and configs as the host for all three AI CLIs (login stays per-container): 1. Drop CLAUDE_CONFIG_DIR from containerEnv. The named-volume mount target `/home/node/.claude` already matches Claude's default `~/.claude`, so the env var added no behavior — but setting it changed which file Claude reads `hasCompletedOnboarding` from. With it set, Claude reads `$CLAUDE_CONFIG_DIR/.claude.json` (the small identity-only file that does NOT carry `hasCompletedOnboarding`); without it, Claude reads `$HOME/.claude.json` (the big onboarding-state file that does). The wizard fires every container-create when set, skips when unset. 2. Sync `settings.json` from host (Claude) + symlink `memories/` and `skills/` from host (Codex). Theme + `enabledPlugins` + `extraKnownMarketplaces` live in `settings.json` — without syncing it, the theme picker fires and host-installed plugins stay disabled even though their files are symlinked in. Codex's `memories/` and `skills/` are the symmetric Codex user-installed surface, now shared the same way Claude's plugins/skills/agents/memory/commands are. Cursor stays as-is — `cli-config.json` conflates auth+settings (already synced), and there's no separate plugin surface to mirror. Login details remain per-container by design (acceptable to re-login on rebuild). Everything else — plugins, skills, agents, memory, MCP user- scope config, project trust, theme, plugin enablement — now matches host on every container-create. * refactor(devcontainer): hybrid RW bind + per-container creds — fixes EROFS on in-container plugin install The previous Option B topology (RO host stage + named volume + symlinks into the volume) made `/plugin marketplace add` inside the container fail with EROFS — the symlinks pointed at a read-only mount, so Claude couldn't create new marketplace dirs. Switch to a hybrid: shareable content (plugins/skills/agents/memory/commands/settings.json/$HOME/.claude.json for Claude; config.toml/memories/skills for Codex) gets a direct RW bind from host so reads and writes go bidirectionally; credentials + the small identity file stay in per-container named volumes so logout in container doesn't log out host. Mount precedence does the heavy lifting: the named volume mounts at /home/node/.<cli> first, then sub-path bind mounts overlay specific sub-paths. Container's view at /home/node/.claude/plugins/ is the host dir; container's view at /home/node/.claude/.credentials.json is the named volume's file. What this gives you: - /plugin marketplace add in container = installed on host - New skill on host = visible in container immediately (no rebuild) - claude logout in container = host stays logged in - compound-engineering plugin enabled on host = enabled in container - Theme picker fires once (or never if host has theme set) What it costs: - Write-through: a compromised npm dep in workspace deps can write to host ~/.claude/{plugins,skills,agents,memory,commands}/. Documented trade-off; for personal dev, accepted. Credentials still per-container. post-create.sh becomes much simpler — only syncs the four credential files from host into the named volumes. No more symlink dance, no more state-file merging. ensure-host-config-dirs.cjs gains the new bind sources: the shareable subdirs and settings.json/config.toml files get mkdir/touched on host so Docker doesn't reject the mount when a CLI has never been used. * fix(devcontainer): translate host plugin registry paths to Linux on rebuild The previous topology bind-mounted the entire `~/.claude/plugins/` directory from host. That brought through plugins, marketplaces, and extracted cache content correctly — but ALSO brought through the registry JSONs (`known_marketplaces.json`, `installed_plugins.json`, `plugin-catalog-cache.json`) which carry absolute OS-native paths: "installLocation": "C:\Users\gergo\.claude\plugins\marketplaces\X" "installPath": "C:\Users\gergo\.claude\plugins\cache\Y\Z" Claude in the Linux container fails to resolve these Windows paths and reports `Marketplace X failed to load: cache-miss`. Split the topology: - `plugins/marketplaces/` (git clones) and `plugins/cache/` (extracted plugin files) stay bidirectional RW binds — content is path-independent. - Registry JSONs move into the per-container named volume. post-create.sh reads host's versions, rewrites any absolute path ending in `/.claude/plugins/<rest>` (Windows `C:\Users\...` and POSIX `/Users/...` / `/home/...` patterns) to `/home/node/.claude/plugins/<rest>`, and writes the translated result to the volume. What this gets you: - Plugin installed on host → next container rebuild has it (translated). - Plugin installed inside container → lives in volume registry; lost on rebuild (consistent with credentials model). Re-install on host for persistence. ensure-host-config-dirs.cjs now also creates `plugins/marketplaces/` and `plugins/cache/` on host if absent (Docker rejects bind mounts whose source doesn't exist). * fix(devcontainer): clean stale plugin/skill symlinks from prior design before writes A user upgrading from Option B (read-only host stage + symlinks) to the current hybrid RW-bind topology hit EROFS in post-create.sh when the plugin registry path-translator tried to write `/home/node/.claude/plugins/known_marketplaces.json`. The named volume still carried `/home/node/.claude/plugins -> /host/.claude/plugins` (Option B's symlink). The new design's sub-path bind mounts at `plugins/marketplaces` and `plugins/cache` overlay through the symlink, but writes to the parent dir itself resolve via the symlink to the RO host stage and fail. Drop any leftover symlinks at known target paths early in step 2 so the mkdir/writes that follow land in the volume. * refactor(devcontainer): split workspace-deps to updateContentCommand post-create.sh was doing two unrelated jobs: workspace dependency install (four `npm install` runs in topological order) and AI CLI credential sync. They have different lifecycle needs — deps should re-run when lockfiles change, AI sync should run once per container — but both were gated on container-create. Per Dev Container spec lifecycle, `updateContentCommand` is the right hook for workspace deps: runs at container-create AND on content changes (lockfile updates). `postCreateCommand` is right for AI CLI sync: container-create only. Move steps 3-7 (husky cleanup + four `npm install` runs) into install-deps.sh wired as `updateContentCommand`. Split the chown step too — install-deps owns workspace-side dirs (node_modules volumes, ~/.npm), post-create owns AI-side dirs (~/.claude, ~/.codex, ~/.cursor, /commandhistory, ~/.local). Each script now has one concern. post-create.sh drops from ~187 lines to 148; install-deps.sh is 56 lines new. Faster rebuilds when nothing about deps changed (the credential sync + path translation work still runs every container-create, but the npm install dance no longer does). Research backing (no other simplification applies): - Anthropic's reference devcontainer uses pure named volumes; no host-state inheritance pattern is published. - Path translation has no upstream fix (issues #21916, #10379 closed without resolution). Our Node rewrite is the workaround. - pnpm workspaces (`pnpm -r install`) would replace the four installs with one command, but that's a real refactor (touches gitnexus/scripts/build.js + 4 package.json files); deferred. - `HUSKY=0` in containerEnv would drop the `rm -rf .husky/_` hack, but would also stop pre-commit hooks from firing inside the container; deferred. * fix(devcontainer): drop single-file binds — fixes Codex `batchWrite failed in TUI` On Docker Desktop Windows the named volumes are ext4 (`/dev/sdd`) while single-file bind mounts from the Windows host land as 9p (drvfs). Different filesystems → atomic config writes (write `foo.tmp`, then rename onto `foo`) trip EXDEV `inter-device move failed` / `Device or resource busy`. Codex's TUI surfaces this as `config/batchWrite failed in TUI` when saving model preference. Claude's writes to settings.json / .claude.json fail the same way, silently. Reproduction in container: $ echo x > /tmp/foo.toml; mv /tmp/foo.toml /home/node/.codex/config.toml mv: inter-device move failed: ... Device or resource busy Fix: drop the three single-file bind mounts. Sync host's versions into the named volume on container-create via `sync_from_host` (same pattern already used for credentials). Atomic rename within the volume works because everything is ext4. Trade-off: container writes to these files no longer propagate to host; they stay in the volume until next rebuild, which re-syncs from host. Host is source of truth on rebuild — same model as credentials. Plugin/ skill/agent/memory/command DIRS still bind-mount bidirectionally (atomic writes within a dir bind stay on one filesystem, no EXDEV). Files affected: - ~/.codex/config.toml - ~/.claude/settings.json - ~/.claude.json (HOME-level — added `/host/.claude.json` RO mount back for sync_from_host to read) * chore(autofix): apply prettier + eslint fixes via /autofix command * feat(devcontainer): Codex + Cursor plugin/config host parity with Claude Codex plugins installed in the container never reached the Windows host because, unlike Claude, the Codex plugin tree wasn't bind-mounted — only memories/ and skills/ were. Verified via live /proc/mounts: Claude binds 6 shareable dirs (incl. plugins/marketplaces + plugins/cache), Codex bound 2. So `codex plugin add` wrote into the ext4 named volume and stayed there. Codex changes: - Bind the WHOLE ~/.codex/plugins dir + ~/.codex/prompts (plus existing memories/skills). Strace of two real `codex plugin add` runs proved the installer stages INSIDE plugins/cache/<marketplace>/ and renames intra-dir, so a single 9p bind of plugins/ keeps the rename intra-fs — no EXDEV (the bug that broke single-file binds). .tmp/ stays on the volume (it's the cross-fs staging source). No path translation needed: Codex enablement lives in config.toml as git URLs, not FS paths. - Verified live: `codex plugin add compound-engineering@...` now writes through to C:\Users\...\.codex\plugins\cache\ on the Windows host, and host-created files appear in the container (bidirectional). Cursor changes (review found cursor-agent has a real plugin surface, not editor-only — Cursor 2.5 Marketplace shared by IDE + CLI): - Bind plugins/marketplaces, plugins/local, rules, commands, agents, skills (dir binds, EXDEV-safe). - Copy-on-create mcp.json (single file → EXDEV-unsafe as bind), alongside the existing cli-config.json. - Translate plugins/installed_plugins.json (carries absolute Windows paths like Claude's) — generalized the existing path-rewrite to run for both Claude and Cursor. - hooks.json deliberately NOT shared (runs shell commands → supply-chain surface); documented as opt-in. ensure-host-config-dirs.cjs pre-creates all new host bind sources. post-create.sh defensive symlink cleanup extended to the new Codex/Cursor paths. README updated with the accurate per-CLI share/sync/translate matrix. Design adversarially verified (straced installs, EXDEV primitive tests, sqlite-under-bind check, path-encoding check) before implementing. * fix(devcontainer): resolve ce-code-review findings (doc drift, chown scope, .cjs extraction, CI smoke) Multi-agent review (9 reviewers) found the devcontainer files carried comments + README from the abandoned read-only-symlink design, plus real behavioral gaps. Resolved all actionable findings (no deferrals). Documentation drift (the headline — stale comments described a security model opposite to what shipped): - README "Trust boundary" claimed a malicious dep "cannot write back … the read-only /host mount blocks the write." FALSE — the shareable dirs are RW-bound. Rewrote to document the bidirectional write-through, what stays one-way (credentials never flow back), and how to close it. - devcontainer.json mount group-1 comment described "selectively symlinks … read-only eliminates write-through" — replaced with the RW-bind reality. - Header "Windows-native is unsupported" -> supported (auto HOME setup). - containerEnv comment "credentials persist in host-bind-mounted dirs" -> they live in the named volumes. - hooks.json exclusion documented honestly as a partial mitigation, not a clean boundary (commands/agents/skills/rules are equally executing). - ~/.local "named volume" -> image directory. Behavioral fixes: - chown -R recursed into the RW host binds (could rewrite host ownership / EPERM-abort provisioning on non-UID-aligned Linux). Switched to `find -xdev` per dir so chown stays on the volume filesystem. - Cursor installer wrapped in `timeout 300` — its inner binary download isn't covered by curl --max-time and could hang docker build forever. - Removed dead CURSOR_VERSION ARG/ENV/build-arg (never consumed; "latest" implied a pin the installer can't honor). Documented why Cursor is unpinned. Extraction + tests (the two inline post-create.sh node heredocs were unlintable and untestable; the path regex had had bugs): - seed-claude-config.cjs — installMethod-strip seed, now with a non-object guard (a bare-value/array host .claude.json could otherwise slip the try/catch and silently re-trigger onboarding) and labeled write errors. - translate-plugin-registries.cjs — plugin-registry path translation with labeled errors. - translate-plugin-registries.test.cjs — 12 tests (Windows/POSIX paths, cross-CLI isolation, nested objects, non-object/empty-config guard). - post-create.sh calls the modules via $SCRIPT_DIR. CI: - .github/workflows/ci-devcontainer.yml — runs the unit tests + shell syntax checks + a `@devcontainers/cli build` smoke on .devcontainer/** changes. Conforms to the repo concurrency convention (validator passes). Documented (real gaps, fixes are honest docs since no correct auto-fix exists): user-scope MCP servers with absolute host command paths don't resolve in-container; user-scope config is copy-on-create so host edits need a rebuild; in-container plugin installs get shadowed by an empty host bind on rebuild (recovery noted); plugin installs are single-writer across checkouts; gh/docker RW-vs-ssh/aws/azure-RO rationale. Verified: fresh `@devcontainers/cli up` succeeds; installMethod stripped, registry translated to Linux paths, credentials node:node, 12/12 tests pass. * fix(devcontainer): set persist-credentials:false on CI checkouts + prettier - zizmor `artipacked` (CodeQL/GitHub Advanced Security) flagged both actions/checkout steps in ci-devcontainer.yml: checkout defaults to persist-credentials:true, leaving GITHUB_TOKEN in .git/config where it can leak into uploaded artifacts. Both jobs are read-only (run tests / build smoke, never push), so persist-credentials:false is correct — matches the repo convention in codeql.yml / ci-tests.yml. - Ran prettier 3.8.0 over the new .cjs modules + test (single-quote/style normalization to match the repo). JSON/YAML were already compliant; README is in .prettierignore; .sh has no prettier parser. Behavior unchanged — 12/12 transform unit tests still pass. * fix(devcontainer): resolve adversarial review findings (pins, RO mounts, tests) Resolves the blocking + actionable findings from the PR #1875 review: - Pin base image by digest as bare name@digest [#1]. The :tag@digest form trips the @devcontainers/cli image-name parser (which builds this image in CI and in VS Code "Reopen in Container"); bare name@digest is the parser-compatible form. Verified by a full local build. - Pin Cursor by version + per-arch sha256 and fetch the artifact directly instead of executing cursor.com/install; fail-closed on mismatch [#2]. - Mount ~/.config/gh and ~/.docker read-only so a compromised dep can't rewrite the host GitHub token / Docker credHelper [#4]. - Pin @devcontainers/cli@0.87.0 in the CI smoke [#5]. - chown via find -xdev in install-deps.sh (symlink-safe; matches post-create.sh) [#6]. - Add filesystem-I/O tests (translate/readHostConfig/seed main/ensurePaths) and refactor ensure-host-config-dirs to be unit-testable [#7]. - Stop pre-creating settings.json/config.toml on the host; only the real single-file bind source (.claude.json) is touched [#10]. - Add a prominent top-of-README security callout for the RW write-through trade-off and reframe the deferred egress firewall as the key missing compensating control [#3, #9]. Full devcontainer build verified locally (digest pull + pinned Cursor download/extract/symlink). 24/24 config-transform tests pass. * fix(devcontainer): resolve local adversarial-review findings (low/nit) Follow-up to a local branch review (run after the cloud review crashed before producing findings); all 5 confirmed findings were low/nit: - chown via `find -xdev -exec chown -h`: add -h so chown acts on a symlink ITSELF, not its target. Without it a dangling node_modules/.bin link aborted provisioning under `set -e`, and a cross-fs symlink target could be dereferenced/rewritten. Verified in a clean container (regular files still chowned; dangling link no longer aborts; cross-fs target untouched). Applied to install-deps.sh and post-create.sh; the inline comments are corrected to describe -xdev (descent bound) and -h (no deref) as the two distinct guards. - Reword the .cjs header claims from "lintable" to "unit-tested and prettier-checked": ESLint applies no rules to .cjs in this repo; CI only prettier-checks them. - README: the initializeCommand is `node ensure-host-config-dirs.cjs`, which creates the full bind-source set, not a bash `mkdir -p` of four dirs. - ci-devcontainer.yml: document that the x64 runner exercises only the amd64 Cursor branch; the arm64 sha/URL is hash-pinned (verified against the published artifact) but not built in CI. - Make the seed chmod-644 test meaningful: pre-create dst at 0o600 so only the explicit chmodSync can widen it (the prior assertion passed under the default umask regardless of whether the chmod ran). 25/25 config-transform tests pass; arm64 + x64 Cursor artifacts verified. * docs(devcontainer): rewrite code comments in plain English The devcontainer comments had grown dense and jargon-heavy. Rewrite them across all 9 files into short, plain-English sentences — same facts and reasoning, just clearer wording. Comments only; no code changed. Verified: the diff touches comment lines only, 25/25 config-transform tests pass, devcontainer.json is still valid JSONC with build.args + readonly mounts unchanged, shell scripts pass `bash -n`, and prettier is clean. * feat(devcontainer): persist AI CLI session state across container recreation Add dedicated per-workspace named volumes (mount group 6) for the three AI CLIs' session/resume state so `claude --resume`, `codex resume`, and `cursor-agent resume` survive a rebuild, a full delete-and-recreate, and the `docker volume rm <cli>-config-*` re-login fix: - Claude -> ~/.claude/projects - Codex -> ~/.codex/sessions - Cursor -> ~/.cursor/chats + ~/.cursor/projects The volumes are SEPARATE from the credential/config volumes and keyed like the node_modules volumes (${localWorkspaceFolderBasename}-...- ${devcontainerId}), so wiping a config volume to force a re-login no longer destroys session history. Session state already survived a plain rebuild (it lived in the config volume); this closes the recreation, volume-rm, and devcontainerId-change gaps. Kept container-private (not host bind mounts) deliberately: transcripts can contain pasted secrets, so a host bind would spill them to host disk, widen the supply-chain write-through surface, and leak cross-project transcripts. A commented-out opt-in host-bind block is included for users who accept that trade-off. post-create.sh: chown each new volume root explicitly (find -xdev stops at the config-volume filesystem boundary and won't descend into them), guarded with `[ -d ] || continue` so a missing root can't abort provisioning under set -e. README: document the topology, what survives vs not, the one-time first-rebuild masking of pre-existing config-volume sessions, updated rebuild/reset commands, and the trust-boundary impact. * feat(devcontainer): isolate host AI-CLI config via seed-once copies + persist claude-mem Replace the read-write host bind mounts for the AI-CLI shareable dirs (Claude skills/agents/memory/commands/plugins; Codex plugins/prompts/ memories/skills; Cursor rules/commands/agents/skills/plugins) with a seed-once copy from a read-only /host/.<cli> stage into the per-container config volume. The container gets its own writable copy and can never write back to the host, closing the write-through vector where a compromised in-container dependency could drop a malicious agent, command, skill, or plugin onto the host for the next host session to auto-load. Add a per-container claude-mem named volume (claude-mem-${devcontainerId}) at /home/node/.claude-mem, seeded once from a read-only /host/.claude-mem stage. claude-mem's multi-GB SQLite + Chroma store is kept off a host bind (unreliable fcntl locking / corruption risk over 9p on Docker Desktop Windows) while still surviving rebuilds. - post-create.sh: seed shareable dirs (marker-gated, seed-once) and run plugin-registry translation per seeded CLI; seed claude-mem behind a completion-sentinel guard that self-heals an interrupted multi-GB copy; chown the claude-mem volume only on first create. - translate-plugin-registries.cjs: add selectRegistries() so translation runs per-CLI seed-once instead of clobbering container-installed plugins. - ensure-host-config-dirs.cjs: add ~/.claude-mem; drop the shareable subdirs (no longer bind sources). - devcontainer.json: drop the RW shareable binds; add the claude-mem volume + read-only stage. - README: rewrite trust-boundary, mount table, and rebuild/reset docs for the copy model. - tests: cover selectRegistries and the trimmed DIRS (30 pass). * feat(devcontainer): add Bun 1.3.14, pinned via build arg Installed by the official bun.sh/install script with the release tag passed as the first positional arg, so the version is pinned even though the install path itself is an unverified remote script (the one such exception in the image — Cursor and the base image stay sha256/digest- pinned). BUN_INSTALL is set in ENV so the binary lands at a known path and the installer's rc-file edits don't matter. unzip is added to apt since the Bun installer extracts a .zip. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(devcontainer): persist gh auth via copy-into-volume model Move ~/.config/gh from a read-only bind to the same read-only host stage + per-container named volume pattern used for the AI CLI credentials. post-create.sh seeds hosts.yml/config.yml from the /host/.config/gh stage into the gh-config volume on create, so an in-container `gh auth login` now persists across rebuilds while the read-only stage still prevents any write-back to the host token. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(devcontainer): bump Claude Code to 2.1.156 for Opus 4.8 The pin was 2.1.153, which predates Opus 4.8 support (added in 2.1.154). With DISABLE_AUTOUPDATER=1 the container never updated past the pin, so Claude Code only offered models up to 4.7. Bump to the latest 2.1.156 so Opus 4.8 is available.
