…gyanpatwari#498) * 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 abhigyanpatwari#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 abhigyanpatwari#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. - abhigyanpatwari#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 abhigyanpatwari#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 abhigyanpatwari#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. Regex changed to lazy match stopping at REPLACING/WITH/period boundary. Targets split on whitespace and filtered against INITIALIZE_CLAUSE_KEYWORDS set. Tests (2 new): - INITIALIZE multi-target: WS-CUSTOMER WS-ORDER WS-LINE-ITEM → 3 - INITIALIZE with REPLACING: only WS-RECORD captured, not keywords Total: 241 tests passing | TypeScript clean

…atwari#756) * 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 abhigyanpatwari#756 review findings on resolveFreeCall Addresses all 7 findings from the PR abhigyanpatwari#756 review comment. Code (R1, finding #1) - Replace the literal `'Class' | 'Struct' | 'Record'` check in `hasClassTarget` with `INSTANTIABLE_CLASS_TYPES.has(c.type)`. Converts an invariant that was previously comment-enforced ("keep this list aligned with INSTANTIABLE_CLASS_TYPES") into one enforced structurally. Any future extension of the set propagates here automatically. The narrower Swift extension dedup block below still uses literal `'Class' | 'Struct'` by design — Swift extensions only produce Class duplicates in practice, Record is deliberately excluded there, and the inline comment now documents that asymmetry. Tests (+12 regression scenarios) Finding #2 — language coverage - Go free function (doStuff()) - Python free function (def helper(): ... helper()) - Rust free function outside any impl block - Java statically-imported function - JavaScript module-level function Each exercises `_resolveCallTargetForTesting` with `callForm='free'` and the language-specific file extension. `resolveFreeCall` has no file-extension branching, so these guard the dispatch chain per language without assuming extractor-specific symbol shapes. Finding #3 — argCount threading - 2-arg overload selected when argCount=2 - 0-arg overload selected when argCount=0 Finding #5 — Tier 3 (global) resolution - Function globally visible but not imported. Asserts exact `TIER_CONFIDENCE.global === 0.5` and `reason === 'global'` to catch silent drift if the tier table is ever refactored. Finding #6 — preComputedArgTypes worker path - String overload matched via preComputedArgTypes=['String'] - Int overload matched via preComputedArgTypes=['int'] (lowercase, mirroring the parse-worker's inferred-literal shape; stored 'Int' is normalized via normalizeJvmTypeName at comparison time) Finding #7 — Enum null-route documentation - Enum-only free call asserts `toBeNull()` with an explanatory comment linking to the INSTANTIABLE_CLASS_TYPES rationale. NOT marked skipped — current behavior is intentional, not broken. Finding #4 — Swift extension dedup guard - Two same-name Class entries at different path lengths; exercises the full dispatch chain: 1. filterCallableCandidates with 'free' strips Class → length 0 2. hasClassTarget triggers resolveStaticCall 3. Homonym ambiguity null-routes per SM-12 round-1 contract 4. Constructor-form retry repopulates with both Classes 5. Dedup block sorts by filePath.length → shortest path wins Verification - `tsc --noEmit` clean - 3064 unit tests pass (+12) - 1766 integration tests pass - Zero regressions Plan: docs/plans/2026-04-09-003-fix-sm13-resolve-free-call-review-findings-plan.md Review: abhigyanpatwari#756 (comment) * refactor(SM-13): extract dedupSwiftExtensionCandidates shared helper Follow-up to the PR abhigyanpatwari#756 review fix. 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: abhigyanpatwari#756 * docs(SM-13): address PR abhigyanpatwari#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: abhigyanpatwari#756 (comment) * test(SM-13): cover ownerless-Constructor retry + PHP free function Two low-severity test gaps from PR abhigyanpatwari#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.

…yanpatwari#770) * Initial plan * SM-19: Replace resolveCallTarget with thin dispatcher Delete the monolithic resolveCallTarget function (~200 lines) and replace it with a 15-line thin dispatcher that routes to resolveMemberCall, resolveStaticCall, or resolveFreeCall. Extract module-alias resolution and file-based member-call fallback into dedicated helper functions. - resolveCallTarget body reduced from ~200 lines to ~15 lines - Extract resolveModuleAliasedCall helper (Python/Ruby module imports) - Extract resolveMemberCallByFile helper (trait dispatch, overload disambiguation) - Extract singleCandidate helper (constructor alias fallback, name-based fallback) - Update unit tests for new dispatcher semantics - Update doc comments referencing deleted D0-D4 paths Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/469eac38-b0c0-4a26-a2ff-3eb06299730b Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * SM-19: Add singleCandidate tail fallback for member calls with unresolvable receiver type Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/469eac38-b0c0-4a26-a2ff-3eb06299730b Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix(SM-19): address all PR abhigyanpatwari#770 review findings + fix CI 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. Formatting - Applied prettier to call-processor.ts (CI format check was failing). Verification - tsc --noEmit clean - 3188 unit tests pass (0 skipped real tests) - 1766 resolver integration tests pass - Zero regressions — all PHP, Rust, and no-heritageMap tests green Review: abhigyanpatwari#770 (comment) * fix(SM-19): restore module-alias narrowing and constructor disambiguation Codex adversarial review on PR abhigyanpatwari#770 surfaced two silent regressions in the SM-19 thin dispatcher: Finding 1 [high] — Typed member calls bypassed module-alias narrowing. 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.

Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/b8c4f6b0-4095-4507-a15d-d8469793efac Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix: narrow Column error match to 'contentHash' in lbug-adapter fallback checks Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/b8c4f6b0-4095-4507-a15d-d8469793efac Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix: address production-readiness review — eliminate competing state, use schema constants, hard-fail on stale DELETE, add incremental filter tests Gap A / Arch Violation 1: Remove duplicate vectorExtensionLoaded flag from embedding-pipeline.ts — delegate to lbug-adapter's loadVectorExtension() which owns the VECTOR extension lifecycle and resets on DB reconnect. Arch Violation 2: Replace all hardcoded 'CodeEmbedding' and 'code_embedding_idx' strings in embedding-pipeline.ts and run-analyze.ts with EMBEDDING_TABLE_NAME, EMBEDDING_INDEX_NAME, and CREATE_VECTOR_INDEX_QUERY imported from schema.ts. Add EMBEDDING_INDEX_NAME export to schema.ts. Gap B: Make DELETE failure for stale vectors a hard throw (not just a warning). Continuing after failed DELETE risks Kuzu vector-index corruption since the constraint requires DELETE-before-INSERT for vector-indexed properties. "not found" / "does not exist" errors are still safe to ignore. STALE_HASH_SENTINEL: Define a named constant in embedding types.ts for the empty-string sentinel convention. Used consistently in lbug-adapter.ts and run-analyze.ts so the invariant is self-documenting. Tests: Add comprehensive unit tests for the incremental filter logic with mocked embedder: - New node → embedded - Unchanged node (hash matches) → skipped - Stale node (hash mismatch) → DELETE + re-embed - STALE_HASH_SENTINEL → treated as stale - Zero nodes after filter → createVectorIndex still called - DELETE failure with non-trivial error → throws Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/b21edee7-c9c5-4742-947b-d0def4fb26aa Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix: tighten error classification — extract isMissingColumnOrTableError helper, remove broad pattern matching - Extract isMissingColumnOrTableError() helper in lbug-adapter for consistent schema-error detection (replaces duplicate inline checks) - Tighten 'contentHash' match: now requires 'property' AND 'contentHash' (Kuzu-specific pattern) instead of broad 'contentHash' substring - Tighten DELETE error check: only ignore 'does not exist' (Kuzu's actual message), not broad 'not found' which could mask connection errors - Fix test node ID/name/filePath consistency Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/b21edee7-c9c5-4742-947b-d0def4fb26aa Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix: CI failures and final review — move STALE_HASH_SENTINEL to schema, tighten error matching, fix test mocking, format - Move STALE_HASH_SENTINEL from embeddings/types.ts to lbug/schema.ts (fixes inverted layer dependency: lbug should not import from embeddings) - Tighten isMissingColumnOrTableError: replace broad msg.includes('not found') with /(table|column|property).*not found/i regex to avoid matching transient errors - Add vi.resetModules() in test beforeEach for explicit module isolation (fixes vi.doMock not intercepting loadVectorExtension in CI) - Skip precomputedHashes.set() on unchanged (return false) path - Run prettier on all 5 files flagged by CI format check Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/e20311fd-4361-47b4-a137-9adc3e533b35 * fix: address remaining review nits — rename precomputedHashes, generalize error matcher, revert package-lock - Rename precomputedHashes → computedStaleHashes (hashes are computed on-demand during filter, only cached for stale nodes being re-embedded) - Remove contentHash-specific clause from isMissingColumnOrTableError — the regex /(table|column|property).*not found/i already covers it - Revert package-lock.json ssh→https protocol change Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/e20311fd-4361-47b4-a137-9adc3e533b35 --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com>
