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).

…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

…coping

#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
magyargergo added a commit that referenced this pull request Mar 26, 2026
#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
magyargergo added a commit that referenced this pull request Mar 26, 2026
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

* 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 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

- eslint: replace unsafe parser.parse() with parseSourceSafe()
- eslint: suppress intentional console.warn/log in sync.ts

- eslint: suppress intentional console.warn in manifest-extractor.ts
- typecheck: restore 'thrift' in ContractType union (was accidentally

* fix(ci): revert unintended group module changes that broke tests

Restore types.ts, config-parser.ts, matching.ts, sync.ts, and
manifest-extractor.ts to upstream/main versions. The original commit
accidentally removed fields (thrift, workspace_deps, exclude_links_paths,
exclude_links_param_only_paths) from DetectConfig/MatchingConfig/ContractType
which are still referenced by matching.test.ts, config-parser.test.ts,
sync.test.ts and other integration tests.

This PR's scope is C++ scope-resolution parity only — group module
type definitions and logic should remain unchanged.

* fix(codeql): address security and quality alerts

- arity-metadata.ts, interpret.ts: replace single-pass template strip
  regex (/<[^>]*>/g) with a while-loop to fully handle nested templates
  like Map<List<int>> — resolves 'Incomplete multi-character sanitization'
- cpp.test.ts: remove unused vitest 'it' import since the file defines
  its own 'it' via createResolverParityIt — resolves 'Assignment to constant'
- include-extractor.test.ts: use fs.mkdtempSync() instead of predictable
  os.tmpdir()+Date.now() paths — resolves 'Insecure temporary file'
- interpret.ts: remove redundant 'name !== undefined' check (already
  guaranteed by early return) — resolves 'Comparison between inconvertible types'

* review: address Claude review findings on PR #1520

- Findings 1-3 (BLOCKERS): restore include-extractor.ts and its test to
  the main baseline. Block-comment fallback regression, suffix-resolve
  false-positive suppression, and the four deleted regression tests
  (#3-#6) are now back. These changes were unrelated to C++ scope
  parity and should not have been in this PR.

- Finding 4 (MAJOR, partial): revert COMPOUND_RECEIVER_MAX_DEPTH 6 to
  4. No C++ test exercises depth > 4 (cpp-chain-call uses a 2-hop
  chain), so the bump risked silent regressions on other migrated
  languages without justification. The wildcard-origin propagation in
  imported-return-types.ts is retained — C++ #include and using
  namespace both emit wildcard-origin bindings (cpp/import-decomposer
  .ts:40,90), so wildcard propagation is causal to C++ parity.

- Finding 6: tighten write-access dedup test with exact per-field
  counts (nameWrites = 2, addrWrites = 1) instead of total-count + sub
  string containment, so a regression in one of the two name writes
  can no longer be masked.

- Finding 8: skipped. Box-drawing characters in cpp/query.ts comments
  match the established convention used in csharp/java/php query
  files.

Finding 5 (int/long normalization tie-breaker) left as documented
follow-up — proper fix requires resolver-level tie-breaker logic and
risks regressing other arity-matching tests.

* fix(cpp): stop #include from leaking class methods and namespace members (U1)

The C++ registry-primary resolver was emitting impossible CALLS edges
for ordinary headers: an including file's unqualified save() resolved
to User::save and unqualified foo() resolved to ns::foo. Two leak
paths converged on localDefs:

1. expandCppWildcardNames (file-local-linkage.ts) iterated the
   flattened localDefs and exported every simple tail, including
   class-owned methods and namespace-contained symbols. Replaced with
   a scope-aware filter: build nodeId -> owning Scope from
   Scope.ownedDefs and skip defs whose owning scope is Namespace or
   Class.

2. The shared global free-call fallback's pickUniqueGlobalCallable
   walks the workspace registry by simple name and would still hit
   class methods / namespace members even with wildcard expansion
   fixed. Plugged the gap via the existing isFileLocalDef hook —
   semantically 'logically invisible cross-file' — by tracking per-
   file non-globally-visible nodeIds (populateCppNonGloballyVisible,
   called from populateOwners) and adding an ownerId !== undefined
   fast-path for class-owned defs.

Side fix in shared finalize-algorithm.ts: when wildcard expansion
resolves to a real target but produces zero propagating names, the
edge was dropped, taking the file-level IMPORTS edge with it.
Preserve the original wildcard edge so #include dependencies survive
even when the header exposes no unqualified bindings.

Tests: cpp-include-no-class-leak, cpp-include-no-namespace-leak, and
cpp-anon-ns-same-file-visible fixtures. Negative tests mode-gated to
REGISTRY_PRIMARY_CPP=1 via the expected-failures registry — legacy
DAG has no scope-aware filtering on the global fallback; backporting
is out of scope. All 2104 resolver integration tests pass under
registry-primary mode.

* fix(cpp): suppress receiver-bound CALLS when integer-width overloads collide (U2)

C++ arity-metadata normalizes int, long, short, unsigned, size_t to
'int' so single-candidate flows like 'process(42L)' match a 'long'-
typed parameter via loose matching. But when both 'process(int)' and
'process(long)' coexist as method overloads, they both end up with
parameterTypes=['int'] in the registry, and pickOverload's narrowing
returns 2 candidates with no way to disambiguate. The previous code
picked candidates[0] arbitrarily, emitting a CALLS edge to the wrong
overload roughly half the time.

Fix:
- Add isOverloadAmbiguousAfterNormalization in overload-narrowing.ts
  that detects >1 candidate sharing identical parameterTypes sequences.
- Have pickOverload return a new OVERLOAD_AMBIGUOUS sentinel when this
  fires.
- In the receiver-bound-calls loop, when pickOverload signals ambiguity,
  suppress the edge AND add the site to handledSites so the late-stage
  emitReferencesViaLookup pass does not re-emit the pre-resolved
  reference. Without the handled-mark, the reference index still
  carries a toDef and emits the same wrong edge.

Graph schema has no ambiguous-target edge model, so emitting two
edges (one per candidate) would require a separate schema change.
Zero-edge is the only safe outcome.

Other languages: the ambiguity check is a precondition gate, not a
behavior change for normal narrowing. Languages whose normalizers do
not collapse distinct types into a single token (verified by grep
over *-arity-metadata.ts) will never produce >1 candidate with
identical parameterTypes from genuinely distinct declarations, so
the branch is effectively C++-only in practice.

Test: cpp-overload-int-long fixture asserts exactly .toBe(0) CALLS
edges. Count=1 = arbitrary pick (the bug); count>1 = unsupported
ambiguous-edge model. Mode-gated to REGISTRY_PRIMARY_CPP=1 — legacy
DAG has no OVERLOAD_AMBIGUOUS wiring; backporting is out of scope.

All 2105 resolver integration tests pass under registry-primary; all
139 cpp tests pass under both modes (3 negative tests skipped in
legacy as documented).

* test(cpp): add integration coverage for anonymous-namespace, using-namespace conflict, and std-shim leakage (U3+U4+U5)

Three new end-to-end fixtures exercise the resolver pipeline against
scenarios that previously had only unit-level coverage or no coverage
at all (Claude review Finding 7):

U3 — cpp-anon-ns-cross-file:
  helper.cpp declares 'namespace { void worker(); }' and calls it
  internally. caller.cpp declares a separate 'void worker()' and calls
  it. Asserts (a) the cross-file CALLS edge from caller's run() does
  not target helper.cpp's anonymous-namespace worker, and (b) the
  same-file edge from helper_entry() to its own worker still resolves
  (positive guard against a 'no edges at all' regression making the
  negative check vacuously pass). Includes a state-isolation guard
  that re-runs the same fixture and asserts identical results,
  proving clearFileLocalNames() is called by the pipeline entry.

U4 — cpp-using-namespace-conflict:
  Two headers each declaring 'namespace a { foo() }' and
  'namespace b { foo() }' respectively, plus a caller doing
  'using namespace a; using namespace b; foo()'. Asserts exactly
  zero CALLS edges. One edge = arbitrary pick (the bug); two edges
  would require an ambiguous-target edge model GitNexus does not
  have. Depends on U1 — without scope-aware filtering, both foo()s
  would already be in the importer's wildcard binding set as simple
  'foo', so the test would pass for the wrong reason.

U5 — cpp-using-namespace-std-smoke:
  Fixture-local 'namespace std { void cout_write(); void println(); }'
  shim rather than real <iostream> — captures the wildcard-leak
  shape deterministically without depending on system-header modeling
  stability (out of scope per plan). Asserts (a) the project-local
  call resolves correctly, (b) no leak to shim STL symbols, and (c)
  no CALLS/ACCESSES edges from the caller into std-shim.h at all.

Negative tests for U2/U4 mode-gated to REGISTRY_PRIMARY_CPP=1 via
the expected-failures registry; legacy DAG lacks the OVERLOAD_AMBIGUOUS
suppression and the namespace-aware filtering, so the leaks persist
there. All 2112 resolver integration tests pass under registry-primary;
all 146 cpp tests pass under both modes (4 negative tests skipped in
legacy as documented).

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(cpp): scope-aware isSuperReceiver classification (U1)

The C++ isSuperReceiver hook used a regex `/^[A-Z]\w*::/` that
misclassified any uppercase-qualified call as a super-receiver call.
Singleton::getInstance(), std::Foo::bar(), and PascalCase namespace
calls all entered the super branch, where the absence of an enclosing
class (or wrong MRO context) dropped the resolution entirely.

Fix:
- New optional ScopeResolver hook isSuperReceiverInContext(text,
  callerScope, scopes). Languages where super classification depends
  on caller context define it; receiver-bound-calls.ts prefers it
  when defined and falls back to the simple isSuperReceiver(text)
  otherwise. Other migrated languages (Python, Java, C#, PHP, Go,
  TypeScript) are unchanged.
- C++ implementation: parse the LHS of '::' from the receiver text,
  resolve via findClassBindingInScope, and return true only when
  the LHS is a class-like def in the caller's enclosing class's MRO.
  Returns false for namespace LHS, unresolved LHS, self-class LHS
  (qualified self-calls aren't super), and any non-'::' form.
- Extended the C++ tree-sitter query to capture the LHS of
  qualified_identifier as @reference.receiver so qualified static
  member calls (Singleton::getInstance()) reach the receiver-bound
  Case 2 (class-name receiver) path. Without the receiver capture,
  qualified calls had no explicit receiver and could not resolve
  through any receiver-bound branch.

Test: cpp-namespace-qualified-not-super fixture. Singleton::getInstance()
from a free function asserts exactly 1 CALLS edge through the
qualified-call path. Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2113 resolver integration tests pass; all 147 cpp tests pass under
both modes.

* fix(cpp): suppress receiver-bound CALLS when default-arg overloads collide (U4)

ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and
'void f(int, int = 0)' are declared on S. The previous resolver
returned the first viable candidate via pickOverload's fallback.

Extended isOverloadAmbiguousAfterNormalization to take an optional
argCount: when provided, the predicate compares only the first
argCount slots of each candidate's parameterTypes. Candidates whose
declared-prefix matches up to argCount are treated as ambiguous
because default arguments make all of them equally viable for the
call.

Without argCount, behavior is unchanged (the original int/long
normalization-collapse contract, full-length equality required).
pickOverload now passes site.arity so default-arg ambiguity fires.

Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has
f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges.
Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2114 resolver integration tests pass; all 148 cpp tests pass
under both modes.

* fix(cpp): two-phase template lookup suppresses dependent-base members (U3)

ISO C++ two-phase name lookup: inside a class template body, unqualified
calls MUST NOT bind to members of a dependent base class. Only this->name
or Base<T>::name forms make the lookup dependent. GCC and Clang both
reject the unqualified form with 'declaration of f must be available'.

Before this fix, GitNexus's global free-call fallback walked the
workspace registry by simple name and bound unqualified calls inside
template bodies to dependent-base members, producing CALLS edges the
compiler would reject.

Implementation:
- New languages/cpp/two-phase-lookup.ts module: per-pipeline state
  recording (className, dependentBaseName) pairs at capture time and
  resolving them to nodeId sets during populateOwners.
- captures.ts detectCppDependentBases walks the AST once finding every
  template_declaration containing a class/struct definition. For each,
  it collects template-parameter names (typename T, class T, non-type
  int N, template-template parameters) and walks each base in the
  base_class_clause checking whether any inner type_identifier matches
  a template parameter. Conservative bias: typename T::U, decltype,
  and template-template-parameter shapes also classified as dependent.
- Extended scope-resolution contract's isCallableVisibleFromCaller
  hook with optional callerScope and scopes fields. C++ implements
  the hook to consult isCppDependentBaseMember: when the candidate
  is a member of a dependent base of the caller's enclosing class,
  the hook returns false and pickUniqueGlobalCallable skips the
  candidate.
- clearFileLocalNames also clears the dependent-base state per
  pipeline run.

Fixtures:
- cpp-two-phase-dependent-base: Derived<T> deriving from Base<T>,
  unqualified f() and i inside Derived's body. Asserts zero CALLS
  edges and zero ACCESSES edges respectively.
- cpp-two-phase-this-qualified, cpp-two-phase-non-dependent-base,
  cpp-two-phase-namespace-free-call-inside-template: positive
  fixtures left as documented gaps (this-> and qualified-name
  resolution inside template bodies are pre-existing resolver
  weaknesses independent of U3). Tracked separately.

Negative test mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-
failures registry; legacy DAG has no two-phase lookup.

All 2116 resolver integration tests pass under registry-primary; all
150 cpp tests pass under both modes (5 negative tests skipped in legacy
as documented).

* fix(cpp): implement V1 ADL (Koenig lookup) for free-function calls (U2)

Plan 2026-05-13-001 U2. Adds argument-dependent lookup as a new
candidate-generating tier in `emitFreeCallFallback`: when ordinary
unqualified lookup is empty, ADL surfaces candidates from each
value-class-typed argument's enclosing namespace.

V1 boundary (locked by cpp-adl-pointer-arg-boundary fixture):
- only direct enclosing-namespace closure
- only directly-named class-type values (pointer / reference / template-
  spec args excluded; closure rules deferred to V2)
- ADL fires ONLY when ordinary lookup is empty (no union-and-resolve)

Parenthesized name `(f)(s)` suppresses ADL per ISO C++
[basic.lookup.argdep]/3.1. Multi-candidate ambiguity (e.g. `process(int)`
vs `process(long)` after C++ int-width normalization) returns the
ADL_AMBIGUOUS sentinel — caller suppresses entirely, mirroring the
OVERLOAD_AMBIGUOUS contract from plan 2026-05-12-002 U2.

Implementation:
- `cpp/adl.ts` — new module: per-pipeline argInfoBySite + noAdlSites Maps
  populated at capture time, classToNamespaceQualifiedName Map populated
  during populateOwners; `pickCppAdlCandidates` returns
  SymbolDefinition | ADL_AMBIGUOUS | undefined
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveAdlCandidates` hook
- `scope-resolution/passes/free-call-fallback.ts` — invokes ADL hook
  between `findCallableBindingInScope` and `pickUniqueGlobalCallable`;
  marks site handled on `'ambiguous'` so emit-references doesn't retry
- `cpp/captures.ts` — detects `parenthesized_expression` function wrap;
  per-arg classification (pointer/reference/value class) preserving the
  shape info the existing arity-narrowing normalizer strips
- `cpp/scope-resolver.ts` — registers hook, populates associated
  namespaces, clears state in loadResolutionConfig

Negative tests (parens, pointer-boundary, ambiguous) gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG has no V1/V2
ADL boundary or ADL_AMBIGUOUS suppression.

154/154 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
147 pass + 7 skipped under =0 (legacy parity baseline).

* fix(cpp): inline namespace transitive walking + qualified namespace resolution (U5)

Plan 2026-05-13-001 U5. Two ISO C++ inline-namespace semantics:

1. Unqualified-lookup transitive visibility: inline-namespace members
   reach the enclosing namespace's scope as if declared there. The
   `populateCppNonGloballyVisible` exemption keeps them globally visible
   so cross-file unqualified lookup finds them.

2. Qualified-receiver transitive visibility: `outer::foo()` resolves to
   `outer::v1::foo()` when `v1` is inline (and through arbitrarily-deep
   nesting like `outer::v1::experimental::foo`, matching libc++ `__1` /
   libstdc++ `__cxx11`).

The second behavior required a new resolver case in
`receiver-bound-calls.ts` (Case 1.5: language-specific qualified-receiver
member lookup) because C++ qualified-namespace member calls had no prior
resolution path — receiver-bound Case 1 only handled
`ParsedImport.kind === 'namespace'` (Python/JS-style) and Case 2 handles
class receivers, neither of which fired for `outer::foo()`. The new
hook `resolveQualifiedReceiverMember` is opt-in; languages without
C++-style qualified-name semantics omit it.

Implementation:
- `cpp/inline-namespaces.ts` — new module: per-pipeline
  `inlineNamespaceRangesByFile` + `inlineNamespaceScopeIds` Sets;
  `markCppInlineNamespaceRange` at capture time;
  `populateCppInlineNamespaceScopes` resolves ranges → scope IDs;
  `resolveCppQualifiedNamespaceMember` walks namespace scopes by simple
  name and descends transitively through inline children only.
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveQualifiedReceiverMember` hook to the contract.
- `scope-resolution/passes/receiver-bound-calls.ts` — Case 1.5 invokes
  the hook between Case 1 (namespace imports) and Case 2 (class-name
  receiver). Returns undefined for non-namespace receivers so Case 2
  still resolves class-qualified calls.
- `cpp/captures.ts` — detects `inline` keyword child on
  `namespace_definition`; records 1-based range to match Scope.range.
- `cpp/file-local-linkage.ts` — `populateCppNonGloballyVisible` exempts
  inline-namespace scopes so cross-file unqualified lookup keeps their
  members visible.
- `cpp/scope-resolver.ts` — wires `populateCppInlineNamespaceScopes`
  into populateOwners (BEFORE `populateCppNonGloballyVisible` so the
  exemption sees populated state); registers
  `resolveQualifiedReceiverMember` hook.

4 fixtures: `cpp-inline-namespace-unqualified`, `-versioned`,
`-nested` (two transitive inline hops, STL `__1` shape), and
`-adl-participation` (composes with U2 — ADL surfaces records declared
inside inline child namespaces). All 4 assert exactly 1 CALLS edge with
correct target file.

Versioned fixture gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp
— legacy DAG can't disambiguate two same-name foos without inline
awareness. Other 3 coincidentally resolve in legacy.

158/158 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
150 pass + 8 skipped under =0 (legacy parity baseline).

* test(cpp): Phase 5 cross-unit composition tests for U1/U2/U3/U5

Plan 2026-05-13-001 Phase 5. Locks in correct behavior at the
intersections between the previously-shipped scope-resolver units.

Enhancement to U1: `isSuperReceiverInContext` strips template-argument
lists (`Base<T>` → `Base`) and namespace prefixes (`outer::v1::Base` →
`Base`) before resolving the receiver in the caller's scope chain. This
makes the super-receiver classification work for template-class
heritage shapes like `Base<T>::method()` and `outer::v1::Base<T>::f()`.

Three fixtures + four tests:

- `cpp-phase5-u1-u3-qualified-base-call`:
  `template<class T> struct Derived : Base<T>` with
  `Base<T>::method()` inside a template body. Asserts NO mis-routing
  (count = 0) — documents the V1 gap that template-class inheritance
  isn't captured as EXTENDS by the legacy DAG, so MRO walks are empty
  and the super branch can't dispatch. The composition still works
  correctly: U1's template-arg-stripping classifies `Base<T>` as a
  super candidate, but the empty-MRO terminates without false edges.

- `cpp-phase5-u2-u3-adl-from-derived`:
  `Derived : Base<T>` where `Base::record` shadows `audit::record`.
  Unqualified `record(e)` inside the template body should resolve via
  ADL to `audit::record` (because U3 + the `isFileLocalDef` class-
  owned filter suppress `Base::record`). Asserts 1 edge to audit.h
  and 0 edges to base.h.

- `cpp-phase5-u3-u5-inline-base`:
  `template<class T> struct Derived : outer::v1::Base<T>` where `v1`
  is inline. Unqualified `f()` inside `Derived<T>::g()` should NOT
  bind to Base::f (dependent-base suppression even across inline
  namespace prefix). Asserts count = 0.

Phase 5 tests asserting no-false-positives are gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG over-
resolves without the template-arg-stripping qualified-receiver path
and without two-phase dependent-base suppression.

162/162 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
152 pass + 10 skipped under =0 (legacy parity baseline).

…lution (#1657)

* perf(scope-resolution): use owner-keyed lookup for Step 2 member resolution (#1656)

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(scope-resolution): index Const/Static in FieldRegistry for Step 2 lookup

Extend FieldRegistry to hold multiple defs per (owner, name), reconcile Const and Static into the owner-keyed index, and wire lookupAllByOwner through the production hook so Step 2 does not drop field kinds the registry never indexed. Pass explicitReceiver on read/write reference sites and document undefined-vs-empty hook semantics for defs fallback.

Co-authored-by: Cursor <cursoragent@cursor.com>

* perf(scope-resolution): centralize O(1) owned-member hook and guard hot path

Extract lookupOwnedMembersByOwner for the production Step 2 hook so merges stay O(1) per registry with no defs.byId scan. Add a perf-contract unit test that throws if byId.values runs when the hook is wired. Reuse a frozen empty sentinel on double miss to avoid per-probe allocations.

Co-authored-by: Cursor <cursoragent@cursor.com>

* chore: drop unused buildFieldRegistry import

* chore(scope-resolution): apply ce-code-review safe_auto fixes

- Drop unreachable return + unused values() capture in perf-contract trap (Finding #7)
- Type lookupOwnedMembersByOwner ownerDefId as DefId (Finding #9)
- Add Static-kind Step 2 lookup test mirroring the Const case (Finding #11)

* docs(field-registry): document lookupFieldByOwner first-wins semantics

Audit of all 6 production callers (call-processor.ts:2279, walkers.ts:535,
receiver-bound-calls.ts:380+730, type-env.ts:627+631) confirms none depends
on last-wins precedence — all treat the return as a generic 'field with
this name owned by this class'. Clarify the JSDoc to surface the semantic
change introduced when FieldRegistry moved from last-wins to append-order
storage (ce-code-review finding #2).

* test(scope-resolution): extend Step 2 perf contract to implicit-self, MRO, field paths

Adds three sibling tests under the Step 2 perf contract describe block, each
asserting defs.byId.values() does NOT execute when ownedMembersByOwner is wired:

- implicit-self receiver via typeBindings.self (no explicitReceiver branch)
- 2-level MRO chain (Child extends Parent, save resolves on Parent at depth 1)
- FieldRegistry read via Step 2 (property lookup, separate registry path)

Pins the perf invariant on every distinct entry into walkReceiverTypeBinding
so a regression bypassing the hook on any sub-path now fails CI immediately
(ce-code-review finding #8).

* test(resolve-references): cover arity-overload filtering via resolveReferenceSites

Pins the orchestration-layer wiring of providers.arityCompatibility:
hook returns [save(arity 1), save(arity 2)], referenceSite.arity = 1,
arityCompatibility verdicts 'compatible'/'incompatible' by parameterCount,
exactly one reference emitted with toDef = the arity-1 overload.

registries.test.ts already covered arity at the buildMethodRegistry level;
this adds the missing entry-point check that resolveReferenceSites threads
providers correctly through to lookupCore.Step5 (ce-code-review finding #10).

* test(resolve-references): add hook-on vs hook-off parity test

Runs resolveReferenceSites twice on the same fixture (Parent.save method
hit + Child.name field hit, Child extends Parent MRO chain) — once with
ownedMembersByOwner wired to a synthetic registry, once with the hook
absent so collectOwnedMembers takes the defs.byId fallback. Asserts:

- stats are identical (sitesProcessed / referencesEmitted / unresolved)
- referenceIndex.bySourceScope entries have equal length
- toDef sets are equal
- each per-site reference (including evidence and depth) is .toEqual

Locks the semantic-parity claim in code while both paths still exist.
Will be removed alongside the fallback in finding #1 (ce-code-review #3).

* test(typescript): probe Step 2 MRO walk against ambient (declare class) base

Adds typescript-ambient-base-class fixture with an export declare class
AmbientBase + Derived extends AmbientBase and a call site d.ambientMethod().
Integration assertions:

- Both classes are detected
- EXTENDS edge Derived → AmbientBase emitted
- CALLS edge to ambient.ts:ambientMethod resolved via MRO walk

Probes the ce-code-review #6 concern that ambient-only owners (whose
bodies are never parsed) might be silently skipped by Step 2 after the
owner-keyed lookup change. Result: the call resolves correctly — the
method signature inside the declare class body still flows through
reconcileOwnership into model.methods, so the hook returns the right
ancestor hits. Residual risk is empirically closed.

* feat(scope-resolution): route nested types via owner-keyed TypeRegistry

Closes the Step 2 contract footgun where 'hook returns [] = authoritative
miss' silently dropped any owned def whose NodeLabel was outside the
method/field if-chain in reconcileOwnership.

- TypeRegistry: add nestedByOwner Map + lookupAllByOwner(owner, simple)
  + registerByOwner(owner, simple, def). Mirrors MethodRegistry/
  FieldRegistry shape; cleared with the rest on cascade clear.
- reconcileOwnership: route class-like NodeLabels (Class/Interface/Enum/
  Struct/Union/Trait/TypeAlias/Typedef/Record/Delegate/Annotation/
  Template/Namespace) via types.registerByOwner. New nestedTypesRegistered
  stat. Idempotent skip via nodeId match.
- validateOwnershipParity: extend the I9 invariant check to nested types.
- lookupOwnedMembersByOwner: merge methods + fields + nested-type hits;
  short-circuit when any one source contributes the full result.

Unblocks future receiver-MRO registries that need to resolve 'Outer.Inner'
through the receiver's type-binding chain (ce-code-review finding #5a).

* refactor(scope-resolution): make ownedMembersByOwner required; delete byId fallback

Per ce-code-review finding #1, the optional-hook design encoded a silent
O(|defs|) perf cliff into the type system: any RegistryContext built
without the hook regressed Step 2 to scanning every def per probe with
no warning. Production wires the hook unconditionally; the fallback was
exercised only by tests.

- RegistryContext.ownedMembersByOwner: required, returns readonly
  SymbolDefinition[] (no | undefined). Implementations MUST return [] on
  authoritative miss.
- collectOwnedMembers in lookup-core.ts collapses to a one-line forward
  to the hook; the defs.byId.values() scan and simpleNameOf helper are
  deleted (simpleNameOf had no other consumers).
- ResolveReferencesInput.ownedMembersByOwner: required to match.
- Tests: drop three fallback-path tests (registries Const fallback,
  resolveReferenceSites no-hook fallback, resolveReferenceSites Const-
  undefined fallback) and the hook-vs-fallback parity test added by
  finding #3. makeCtx in registries.test.ts now defaults to a real
  owner-keyed scan over the test fixture defs so tests that don't care
  about the hook keep working.

* perf(free-call-fallback): cache global callables by simple name once per pass

pickUniqueGlobalCallable scanned scopes.defs.byId.values() on every
free-call fallback site. After PR #1656 fixed Step 2, this scan became
the dominant remaining O(|defs|) hot path on large repos (ce-code-review
finding #4).

- buildGlobalCallableIndex builds a Map<simpleName, SymbolDefinition[]>
  over scopes.defs once at the top of emitFreeCallFallback. Same filter
  the per-site scan applied: Function / Method / Constructor, keyed by
  the last .-segment of qualifiedName.
- pickUniqueGlobalCallable consumes the prebuilt index via O(1) Map.get
  instead of iterating every def. Per-site complexity drops from
  O(|defs|) to O(|defs with this simple name|).
- Cost: O(|defs|) once per pass instead of O(|defs| * |free-call sites|).

Subsequent narrowing (arity, conversion-rank) and the model-side fallback
(model.symbols.lookupCallableByName + model.methods.lookupMethodByName)
are unchanged.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* ci: trigger build

…ri#938) (abhigyanpatwari#1520)

* fix(ci): revert unintended group module changes that broke tests

Restore types.ts, config-parser.ts, matching.ts, sync.ts, and
manifest-extractor.ts to upstream/main versions. The original commit
accidentally removed fields (thrift, workspace_deps, exclude_links_paths,
exclude_links_param_only_paths) from DetectConfig/MatchingConfig/ContractType
which are still referenced by matching.test.ts, config-parser.test.ts,
sync.test.ts and other integration tests.

This PR's scope is C++ scope-resolution parity only — group module
type definitions and logic should remain unchanged.

* fix(codeql): address security and quality alerts

- arity-metadata.ts, interpret.ts: replace single-pass template strip
  regex (/<[^>]*>/g) with a while-loop to fully handle nested templates
  like Map<List<int>> — resolves 'Incomplete multi-character sanitization'
- cpp.test.ts: remove unused vitest 'it' import since the file defines
  its own 'it' via createResolverParityIt — resolves 'Assignment to constant'
- include-extractor.test.ts: use fs.mkdtempSync() instead of predictable
  os.tmpdir()+Date.now() paths — resolves 'Insecure temporary file'
- interpret.ts: remove redundant 'name !== undefined' check (already
  guaranteed by early return) — resolves 'Comparison between inconvertible types'

* review: address Claude review findings on PR abhigyanpatwari#1520

- Findings 1-3 (BLOCKERS): restore include-extractor.ts and its test to
  the main baseline. Block-comment fallback regression, suffix-resolve
  false-positive suppression, and the four deleted regression tests
  (abhigyanpatwari#3-abhigyanpatwari#6) are now back. These changes were unrelated to C++ scope
  parity and should not have been in this PR.

- Finding 4 (MAJOR, partial): revert COMPOUND_RECEIVER_MAX_DEPTH 6 to
  4. No C++ test exercises depth > 4 (cpp-chain-call uses a 2-hop
  chain), so the bump risked silent regressions on other migrated
  languages without justification. The wildcard-origin propagation in
  imported-return-types.ts is retained — C++ #include and using
  namespace both emit wildcard-origin bindings (cpp/import-decomposer
  .ts:40,90), so wildcard propagation is causal to C++ parity.

- Finding 6: tighten write-access dedup test with exact per-field
  counts (nameWrites = 2, addrWrites = 1) instead of total-count + sub
  string containment, so a regression in one of the two name writes
  can no longer be masked.

- Finding 8: skipped. Box-drawing characters in cpp/query.ts comments
  match the established convention used in csharp/java/php query
  files.

Finding 5 (int/long normalization tie-breaker) left as documented
follow-up — proper fix requires resolver-level tie-breaker logic and
risks regressing other arity-matching tests.

* fix(cpp): stop #include from leaking class methods and namespace members (U1)

The C++ registry-primary resolver was emitting impossible CALLS edges
for ordinary headers: an including file's unqualified save() resolved
to User::save and unqualified foo() resolved to ns::foo. Two leak
paths converged on localDefs:

1. expandCppWildcardNames (file-local-linkage.ts) iterated the
   flattened localDefs and exported every simple tail, including
   class-owned methods and namespace-contained symbols. Replaced with
   a scope-aware filter: build nodeId -> owning Scope from
   Scope.ownedDefs and skip defs whose owning scope is Namespace or
   Class.

2. The shared global free-call fallback's pickUniqueGlobalCallable
   walks the workspace registry by simple name and would still hit
   class methods / namespace members even with wildcard expansion
   fixed. Plugged the gap via the existing isFileLocalDef hook —
   semantically 'logically invisible cross-file' — by tracking per-
   file non-globally-visible nodeIds (populateCppNonGloballyVisible,
   called from populateOwners) and adding an ownerId !== undefined
   fast-path for class-owned defs.

Side fix in shared finalize-algorithm.ts: when wildcard expansion
resolves to a real target but produces zero propagating names, the
edge was dropped, taking the file-level IMPORTS edge with it.
Preserve the original wildcard edge so #include dependencies survive
even when the header exposes no unqualified bindings.

Tests: cpp-include-no-class-leak, cpp-include-no-namespace-leak, and
cpp-anon-ns-same-file-visible fixtures. Negative tests mode-gated to
REGISTRY_PRIMARY_CPP=1 via the expected-failures registry — legacy
DAG has no scope-aware filtering on the global fallback; backporting
is out of scope. All 2104 resolver integration tests pass under
registry-primary mode.

* fix(cpp): suppress receiver-bound CALLS when integer-width overloads collide (U2)

C++ arity-metadata normalizes int, long, short, unsigned, size_t to
'int' so single-candidate flows like 'process(42L)' match a 'long'-
typed parameter via loose matching. But when both 'process(int)' and
'process(long)' coexist as method overloads, they both end up with
parameterTypes=['int'] in the registry, and pickOverload's narrowing
returns 2 candidates with no way to disambiguate. The previous code
picked candidates[0] arbitrarily, emitting a CALLS edge to the wrong
overload roughly half the time.

Fix:
- Add isOverloadAmbiguousAfterNormalization in overload-narrowing.ts
  that detects >1 candidate sharing identical parameterTypes sequences.
- Have pickOverload return a new OVERLOAD_AMBIGUOUS sentinel when this
  fires.
- In the receiver-bound-calls loop, when pickOverload signals ambiguity,
  suppress the edge AND add the site to handledSites so the late-stage
  emitReferencesViaLookup pass does not re-emit the pre-resolved
  reference. Without the handled-mark, the reference index still
  carries a toDef and emits the same wrong edge.

Graph schema has no ambiguous-target edge model, so emitting two
edges (one per candidate) would require a separate schema change.
Zero-edge is the only safe outcome.

Other languages: the ambiguity check is a precondition gate, not a
behavior change for normal narrowing. Languages whose normalizers do
not collapse distinct types into a single token (verified by grep
over *-arity-metadata.ts) will never produce >1 candidate with
identical parameterTypes from genuinely distinct declarations, so
the branch is effectively C++-only in practice.

Test: cpp-overload-int-long fixture asserts exactly .toBe(0) CALLS
edges. Count=1 = arbitrary pick (the bug); count>1 = unsupported
ambiguous-edge model. Mode-gated to REGISTRY_PRIMARY_CPP=1 — legacy
DAG has no OVERLOAD_AMBIGUOUS wiring; backporting is out of scope.

All 2105 resolver integration tests pass under registry-primary; all
139 cpp tests pass under both modes (3 negative tests skipped in
legacy as documented).

* test(cpp): add integration coverage for anonymous-namespace, using-namespace conflict, and std-shim leakage (U3+U4+U5)

Three new end-to-end fixtures exercise the resolver pipeline against
scenarios that previously had only unit-level coverage or no coverage
at all (Claude review Finding 7):

U3 — cpp-anon-ns-cross-file:
  helper.cpp declares 'namespace { void worker(); }' and calls it
  internally. caller.cpp declares a separate 'void worker()' and calls
  it. Asserts (a) the cross-file CALLS edge from caller's run() does
  not target helper.cpp's anonymous-namespace worker, and (b) the
  same-file edge from helper_entry() to its own worker still resolves
  (positive guard against a 'no edges at all' regression making the
  negative check vacuously pass). Includes a state-isolation guard
  that re-runs the same fixture and asserts identical results,
  proving clearFileLocalNames() is called by the pipeline entry.

U4 — cpp-using-namespace-conflict:
  Two headers each declaring 'namespace a { foo() }' and
  'namespace b { foo() }' respectively, plus a caller doing
  'using namespace a; using namespace b; foo()'. Asserts exactly
  zero CALLS edges. One edge = arbitrary pick (the bug); two edges
  would require an ambiguous-target edge model GitNexus does not
  have. Depends on U1 — without scope-aware filtering, both foo()s
  would already be in the importer's wildcard binding set as simple
  'foo', so the test would pass for the wrong reason.

U5 — cpp-using-namespace-std-smoke:
  Fixture-local 'namespace std { void cout_write(); void println(); }'
  shim rather than real <iostream> — captures the wildcard-leak
  shape deterministically without depending on system-header modeling
  stability (out of scope per plan). Asserts (a) the project-local
  call resolves correctly, (b) no leak to shim STL symbols, and (c)
  no CALLS/ACCESSES edges from the caller into std-shim.h at all.

Negative tests for U2/U4 mode-gated to REGISTRY_PRIMARY_CPP=1 via
the expected-failures registry; legacy DAG lacks the OVERLOAD_AMBIGUOUS
suppression and the namespace-aware filtering, so the leaks persist
there. All 2112 resolver integration tests pass under registry-primary;
all 146 cpp tests pass under both modes (4 negative tests skipped in
legacy as documented).

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(cpp): scope-aware isSuperReceiver classification (U1)

The C++ isSuperReceiver hook used a regex `/^[A-Z]\w*::/` that
misclassified any uppercase-qualified call as a super-receiver call.
Singleton::getInstance(), std::Foo::bar(), and PascalCase namespace
calls all entered the super branch, where the absence of an enclosing
class (or wrong MRO context) dropped the resolution entirely.

Fix:
- New optional ScopeResolver hook isSuperReceiverInContext(text,
  callerScope, scopes). Languages where super classification depends
  on caller context define it; receiver-bound-calls.ts prefers it
  when defined and falls back to the simple isSuperReceiver(text)
  otherwise. Other migrated languages (Python, Java, C#, PHP, Go,
  TypeScript) are unchanged.
- C++ implementation: parse the LHS of '::' from the receiver text,
  resolve via findClassBindingInScope, and return true only when
  the LHS is a class-like def in the caller's enclosing class's MRO.
  Returns false for namespace LHS, unresolved LHS, self-class LHS
  (qualified self-calls aren't super), and any non-'::' form.
- Extended the C++ tree-sitter query to capture the LHS of
  qualified_identifier as @reference.receiver so qualified static
  member calls (Singleton::getInstance()) reach the receiver-bound
  Case 2 (class-name receiver) path. Without the receiver capture,
  qualified calls had no explicit receiver and could not resolve
  through any receiver-bound branch.

Test: cpp-namespace-qualified-not-super fixture. Singleton::getInstance()
from a free function asserts exactly 1 CALLS edge through the
qualified-call path. Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2113 resolver integration tests pass; all 147 cpp tests pass under
both modes.

* fix(cpp): suppress receiver-bound CALLS when default-arg overloads collide (U4)

ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and
'void f(int, int = 0)' are declared on S. The previous resolver
returned the first viable candidate via pickOverload's fallback.

Extended isOverloadAmbiguousAfterNormalization to take an optional
argCount: when provided, the predicate compares only the first
argCount slots of each candidate's parameterTypes. Candidates whose
declared-prefix matches up to argCount are treated as ambiguous
because default arguments make all of them equally viable for the
call.

Without argCount, behavior is unchanged (the original int/long
normalization-collapse contract, full-length equality required).
pickOverload now passes site.arity so default-arg ambiguity fires.

Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has
f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges.
Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2114 resolver integration tests pass; all 148 cpp tests pass
under both modes.

* fix(cpp): two-phase template lookup suppresses dependent-base members (U3)

ISO C++ two-phase name lookup: inside a class template body, unqualified
calls MUST NOT bind to members of a dependent base class. Only this->name
or Base<T>::name forms make the lookup dependent. GCC and Clang both
reject the unqualified form with 'declaration of f must be available'.

Before this fix, GitNexus's global free-call fallback walked the
workspace registry by simple name and bound unqualified calls inside
template bodies to dependent-base members, producing CALLS edges the
compiler would reject.

Implementation:
- New languages/cpp/two-phase-lookup.ts module: per-pipeline state
  recording (className, dependentBaseName) pairs at capture time and
  resolving them to nodeId sets during populateOwners.
- captures.ts detectCppDependentBases walks the AST once finding every
  template_declaration containing a class/struct definition. For each,
  it collects template-parameter names (typename T, class T, non-type
  int N, template-template parameters) and walks each base in the
  base_class_clause checking whether any inner type_identifier matches
  a template parameter. Conservative bias: typename T::U, decltype,
  and template-template-parameter shapes also classified as dependent.
- Extended scope-resolution contract's isCallableVisibleFromCaller
  hook with optional callerScope and scopes fields. C++ implements
  the hook to consult isCppDependentBaseMember: when the candidate
  is a member of a dependent base of the caller's enclosing class,
  the hook returns false and pickUniqueGlobalCallable skips the
  candidate.
- clearFileLocalNames also clears the dependent-base state per
  pipeline run.

Fixtures:
- cpp-two-phase-dependent-base: Derived<T> deriving from Base<T>,
  unqualified f() and i inside Derived's body. Asserts zero CALLS
  edges and zero ACCESSES edges respectively.
- cpp-two-phase-this-qualified, cpp-two-phase-non-dependent-base,
  cpp-two-phase-namespace-free-call-inside-template: positive
  fixtures left as documented gaps (this-> and qualified-name
  resolution inside template bodies are pre-existing resolver
  weaknesses independent of U3). Tracked separately.

Negative test mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-
failures registry; legacy DAG has no two-phase lookup.

All 2116 resolver integration tests pass under registry-primary; all
150 cpp tests pass under both modes (5 negative tests skipped in legacy
as documented).

* fix(cpp): implement V1 ADL (Koenig lookup) for free-function calls (U2)

Plan 2026-05-13-001 U2. Adds argument-dependent lookup as a new
candidate-generating tier in `emitFreeCallFallback`: when ordinary
unqualified lookup is empty, ADL surfaces candidates from each
value-class-typed argument's enclosing namespace.

V1 boundary (locked by cpp-adl-pointer-arg-boundary fixture):
- only direct enclosing-namespace closure
- only directly-named class-type values (pointer / reference / template-
  spec args excluded; closure rules deferred to V2)
- ADL fires ONLY when ordinary lookup is empty (no union-and-resolve)

Parenthesized name `(f)(s)` suppresses ADL per ISO C++
[basic.lookup.argdep]/3.1. Multi-candidate ambiguity (e.g. `process(int)`
vs `process(long)` after C++ int-width normalization) returns the
ADL_AMBIGUOUS sentinel — caller suppresses entirely, mirroring the
OVERLOAD_AMBIGUOUS contract from plan 2026-05-12-002 U2.

Implementation:
- `cpp/adl.ts` — new module: per-pipeline argInfoBySite + noAdlSites Maps
  populated at capture time, classToNamespaceQualifiedName Map populated
  during populateOwners; `pickCppAdlCandidates` returns
  SymbolDefinition | ADL_AMBIGUOUS | undefined
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveAdlCandidates` hook
- `scope-resolution/passes/free-call-fallback.ts` — invokes ADL hook
  between `findCallableBindingInScope` and `pickUniqueGlobalCallable`;
  marks site handled on `'ambiguous'` so emit-references doesn't retry
- `cpp/captures.ts` — detects `parenthesized_expression` function wrap;
  per-arg classification (pointer/reference/value class) preserving the
  shape info the existing arity-narrowing normalizer strips
- `cpp/scope-resolver.ts` — registers hook, populates associated
  namespaces, clears state in loadResolutionConfig

Negative tests (parens, pointer-boundary, ambiguous) gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG has no V1/V2
ADL boundary or ADL_AMBIGUOUS suppression.

154/154 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
147 pass + 7 skipped under =0 (legacy parity baseline).

* fix(cpp): inline namespace transitive walking + qualified namespace resolution (U5)

Plan 2026-05-13-001 U5. Two ISO C++ inline-namespace semantics:

1. Unqualified-lookup transitive visibility: inline-namespace members
   reach the enclosing namespace's scope as if declared there. The
   `populateCppNonGloballyVisible` exemption keeps them globally visible
   so cross-file unqualified lookup finds them.

2. Qualified-receiver transitive visibility: `outer::foo()` resolves to
   `outer::v1::foo()` when `v1` is inline (and through arbitrarily-deep
   nesting like `outer::v1::experimental::foo`, matching libc++ `__1` /
   libstdc++ `__cxx11`).

The second behavior required a new resolver case in
`receiver-bound-calls.ts` (Case 1.5: language-specific qualified-receiver
member lookup) because C++ qualified-namespace member calls had no prior
resolution path — receiver-bound Case 1 only handled
`ParsedImport.kind === 'namespace'` (Python/JS-style) and Case 2 handles
class receivers, neither of which fired for `outer::foo()`. The new
hook `resolveQualifiedReceiverMember` is opt-in; languages without
C++-style qualified-name semantics omit it.

Implementation:
- `cpp/inline-namespaces.ts` — new module: per-pipeline
  `inlineNamespaceRangesByFile` + `inlineNamespaceScopeIds` Sets;
  `markCppInlineNamespaceRange` at capture time;
  `populateCppInlineNamespaceScopes` resolves ranges → scope IDs;
  `resolveCppQualifiedNamespaceMember` walks namespace scopes by simple
  name and descends transitively through inline children only.
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveQualifiedReceiverMember` hook to the contract.
- `scope-resolution/passes/receiver-bound-calls.ts` — Case 1.5 invokes
  the hook between Case 1 (namespace imports) and Case 2 (class-name
  receiver). Returns undefined for non-namespace receivers so Case 2
  still resolves class-qualified calls.
- `cpp/captures.ts` — detects `inline` keyword child on
  `namespace_definition`; records 1-based range to match Scope.range.
- `cpp/file-local-linkage.ts` — `populateCppNonGloballyVisible` exempts
  inline-namespace scopes so cross-file unqualified lookup keeps their
  members visible.
- `cpp/scope-resolver.ts` — wires `populateCppInlineNamespaceScopes`
  into populateOwners (BEFORE `populateCppNonGloballyVisible` so the
  exemption sees populated state); registers
  `resolveQualifiedReceiverMember` hook.

4 fixtures: `cpp-inline-namespace-unqualified`, `-versioned`,
`-nested` (two transitive inline hops, STL `__1` shape), and
`-adl-participation` (composes with U2 — ADL surfaces records declared
inside inline child namespaces). All 4 assert exactly 1 CALLS edge with
correct target file.

Versioned fixture gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp
— legacy DAG can't disambiguate two same-name foos without inline
awareness. Other 3 coincidentally resolve in legacy.

158/158 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
150 pass + 8 skipped under =0 (legacy parity baseline).

* test(cpp): Phase 5 cross-unit composition tests for U1/U2/U3/U5

Plan 2026-05-13-001 Phase 5. Locks in correct behavior at the
intersections between the previously-shipped scope-resolver units.

Enhancement to U1: `isSuperReceiverInContext` strips template-argument
lists (`Base<T>` → `Base`) and namespace prefixes (`outer::v1::Base` →
`Base`) before resolving the receiver in the caller's scope chain. This
makes the super-receiver classification work for template-class
heritage shapes like `Base<T>::method()` and `outer::v1::Base<T>::f()`.

Three fixtures + four tests:

- `cpp-phase5-u1-u3-qualified-base-call`:
  `template<class T> struct Derived : Base<T>` with
  `Base<T>::method()` inside a template body. Asserts NO mis-routing
  (count = 0) — documents the V1 gap that template-class inheritance
  isn't captured as EXTENDS by the legacy DAG, so MRO walks are empty
  and the super branch can't dispatch. The composition still works
  correctly: U1's template-arg-stripping classifies `Base<T>` as a
  super candidate, but the empty-MRO terminates without false edges.

- `cpp-phase5-u2-u3-adl-from-derived`:
  `Derived : Base<T>` where `Base::record` shadows `audit::record`.
  Unqualified `record(e)` inside the template body should resolve via
  ADL to `audit::record` (because U3 + the `isFileLocalDef` class-
  owned filter suppress `Base::record`). Asserts 1 edge to audit.h
  and 0 edges to base.h.

- `cpp-phase5-u3-u5-inline-base`:
  `template<class T> struct Derived : outer::v1::Base<T>` where `v1`
  is inline. Unqualified `f()` inside `Derived<T>::g()` should NOT
  bind to Base::f (dependent-base suppression even across inline
  namespace prefix). Asserts count = 0.

Phase 5 tests asserting no-false-positives are gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG over-
resolves without the template-arg-stripping qualified-receiver path
and without two-phase dependent-base suppression.

162/162 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
152 pass + 10 skipped under =0 (legacy parity baseline).

…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.

…moke

Resolves all findings from the automated production-readiness review on
verify/issue-1728-symlink.

Swift warning parity (review #2):
  Add tree-sitter-swift to OPTIONAL_GRAMMARS in src/cli/optional-grammars.ts
  alongside Dart and Proto. Before this commit, Swift was materialized at
  postinstall and probed by build-tree-sitter-swift.cjs but the runtime
  warnMissingOptionalGrammars() never warned when it failed to load —
  users got silent Swift degradation from the optional-grammars surface
  (parser-loader's separate unavailableNote only fires on demand). Now
  the warning path matches the materialize path.

README env-var table (review #1):
  Update the GITNEXUS_SKIP_OPTIONAL_GRAMMARS row at README.md line 248 to
  list all three vendored grammars (dart, proto, swift). The quick note
  earlier in the README already mentioned all three; only the table row
  was stale.

Atomicity hardening (review #3):
  materialize-vendor-grammars.cjs now copies to {dest}.materialize-tmp,
  renames the existing dest to {dest}.materialize-bak (if present), then
  renames the partial into dest, then removes the backup. 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.

…) (#1729)

* fix(install): materialize vendored grammars to fix Windows EPERM (#1728)

Stop using file: optionalDependencies for tree-sitter-dart/proto/swift,
which made npm symlink vendor paths on install and fail on Windows without
symlink privileges. Copy vendor trees into node_modules at postinstall
instead; keep native builds and #836 vendor hygiene.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(install): atomic materialize swap + fail-soft tests (#1728, #836)

Hardens PR #1729 against two issues the original implementation could
still hit:

1. Torn-state on rmSync→cpSync. The previous loop deleted the
   destination before copying. If cpSync threw — the exact Windows EPERM
   scenario this PR targets — a previously-working grammar was silently
   wiped. Now we copy to {dest}.materialize-tmp first and renameSync into
   place, so an interrupted copy leaves the prior materialization intact.

2. Fail-soft try/catch had no test coverage. Adds two POSIX-only tests
   (chmod 0o555 to deterministically force cpSync to throw) that verify
   (a) a single grammar failure does not abort the other two, and (b) an
   existing materialization survives a partial-copy failure. Skipped on
   Windows where chmod doesn't enforce write restriction; runs on Linux
   CI.

Other test improvements locking in the install-hygiene invariants:

- All three vendored grammars (dart/proto/swift) checked, not just dart.
- GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1 short-circuit is exercised.
- Vendor cleanliness (#836): no node_modules/build under vendor/.
- Idempotent re-runs (clean overwrite verified via sentinel file).
- Missing-vendor warn+continue path now has explicit coverage.
- Vendored package manifests asserted to carry no install script or
  runtime dependencies.
- package.json optionalDependencies asserted free of vendored grammars.
- package-lock.json assertion tightened from `if (entry !== undefined)
  { expect(entry.link).not.toBe(true); }` (vacuous when entry is absent,
  i.e. the expected post-fix state) to `expect(...).toBeUndefined()`.

Verified locally:
- npx tsc --noEmit: clean
- vitest test/unit/materialize-vendor-grammars.test.ts: 8 pass + 2
  POSIX-only skipped on Windows
- npm pack tarball: no vendor/*/node_modules or vendor/*/build entries
- Isolated global install (clean + upgrade + SKIP env) into temp prefix:
  succeeds; gitnexus --version → 1.6.5; vendor stays clean post-install.

* fix(install): address review feedback — Swift parity, atomicity, CI smoke

Resolves all findings from the automated production-readiness review on
verify/issue-1728-symlink.

* 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).

* 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.

* feat(mcp): add limit/offset/summaryOnly pagination to impact tool (#414)

The impact tool returns unbounded byDepth arrays for hub symbols (base
error classes, shared utilities), producing 140KB+ responses that get
truncated by MCP clients. maxDepth alone does not help when most
dependents are at depth 1.

Add three new parameters:
- summaryOnly: returns counts/risk/processes/modules without byDepth
- limit: caps symbols per depth level (default 100)
- offset: skips symbols for pagination

Also adds byDepthCounts to all responses so agents can see total counts
even when the symbol list is paginated or omitted.

Closes #414

* fix(mcp): prevent pagination from silently truncating cross-repo impact

Address review findings on #1818:

- F1 (blocker): _runImpactBFS no longer defaults to limit 100 when
  limit is not set — only _impactImpl (MCP entry) applies the default.
  Internal callers (impactByUid, group impact) get complete results.
  GroupToolPort.impact interface gains optional limit param, and
  cross-impact.ts passes limit: 10000 for local UID collection.

- F2 (blocker): tool description updated — byDepth is now documented
  as paginated, not 'all affected symbols'.

- F3: impactByUid calls _runImpactBFS without limit, so Phase-2
  neighbor results are no longer capped at 100.

- F4: pagination metadata now appears when offset > 0 (head truncation),
  not just tail truncation. Pagination.limit is null when uncapped.

- F5: limit/offset schema types changed from number to integer;
  Math.trunc applied in implementation as defense-in-depth.

- F6: 7 new tests — multi-depth pagination, offset-only truncation,
  offset past end, float inputs, _runImpactBFS internal uncapped path,
  collectImpactSymbolUids with paginated vs complete data.

* fix(mcp): NaN guard on pagination params, complete GroupToolPort interface

- Add Number.isFinite guard to limit/offset in _runImpactBFS so NaN
  inputs fall through to uncapped/zero defaults instead of producing
  silent empty byDepth with no truncation signal.

- Add offset and summaryOnly to GroupToolPort.impact interface to
  match the implementation and prevent silent param loss at the
  port boundary.

- Replace bounds-only toBeLessThan assertion with exact byDepthCounts
  and pagination assertions per DoD §2.7.

* fix(mcp): address remaining review findings for impact pagination

- #3: Forward limit/offset/summaryOnly through callToolAtGroupRepo
  so group-mode MCP callers can use the new pagination params.

- #4: Extract GROUP_LOCAL_PHASE_LIMIT constant from magic 10000 in

fix(mcp): address Copilot review feedback on impact pagination

- Sanitize limit/offset with Number.isFinite in _impactImpl to prevent
  NaN passthrough from bypassing the default limit of 100
- Omit pagination.limit field instead of emitting null when paginationLimit
  is Infinity, keeping the response schema consistent
- Move GROUP_LOCAL_PHASE_LIMIT after all imports in cross-impact.ts
- Stop forwarding limit/offset/summaryOnly to group-mode impact since
  runGroupImpact overrides limit with GROUP_LOCAL_PHASE_LIMIT for UID
  collection and does not re-paginate
- Validate CLI parseInt results with Number.isFinite before passing to
  the backend, falling back to undefined so defaults apply
- Use byDepthCounts to decide whether to render depth sections in
  formatImpactResult, handling empty pages from offset past end

fix(mcp): address code review findings on impact pagination

- Fix formatImpactResult "N more" count: use Math.min(items.length, 12)
  instead of hardcoded 12, so paginated pages with <12 items show the
  correct remaining count
- Detect summaryOnly responses (byDepth absent, byDepthCounts present)
  and show a summary-mode message instead of misleading "(0 items on
  this page — adjust offset)" per depth level
- Document that limit/offset/summaryOnly are single-repo only and
  ignored in group mode (@groupName) in MCP tool schema descriptions
- List byDepthCounts in summaryOnly description and note byDepth
  absence when summaryOnly is true
- Remove unused limit/offset/summaryOnly from GroupToolPort.impact
  interface since they are never forwarded to group impact
- Deduplicate parseInt calls in CLI tool.ts: extract to local variables
  with consistent optional-chain usage

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.

Note: Compare/Play SUCCESS still needs warm baselines/diffs for the target

## P0 abhigyanpatwari#1 — missing scope-resolution hooks in vueProvider
`pass3CollectImports` early-returns when `interpretImport` is undefined,
producing zero IMPORTS and zero cross-file CALLS edges. Add the four
hooks to `vueProvider` in `vue.ts`:
  - `interpretImport: interpretTsImport`
  - `interpretTypeBinding: interpretTsTypeBinding`
  - `bindingScopeFor: tsBindingScopeFor`
  - `importOwningScope: tsImportOwningScope`
Also add `receiverBinding`, `mergeBindings`, `arityCompatibility`, and
`resolveImportTarget` to complete the scope-resolution contract.

## P0 abhigyanpatwari#2 — template-component CALLS dropped when Vue is registry-primary
`isRegistryPrimary(Vue) → true` makes the main call-processor loop skip
Vue files entirely, silencing the inline `vue-template-component` CALLS
emitter at ≈L1506. Add a dedicated post-loop pass in `call-processor.ts`
that emits template-component CALLS for Vue files whenever Vue is
registry-primary. Update the stale `vue/index.ts` limitation comment to
reflect the new emit site.

## P1 abhigyanpatwari#3 — worker-mode double-extraction → zero captures
In worker mode (≥15 files) the parse worker pre-extracts the `<script>`
block and passes `scriptContent` as `sourceText`. `emitVueScopeCaptures`
was calling `extractVueScript` a second time, getting null, and returning
`[]`. Fix: if extraction returns null and the content has no SFC block-
level markers (`<template`, `<style`), treat it as already-extracted
script text and delegate directly to `emitTsScopeCaptures`.

## Test assertion strictness
Replace all `toBeGreaterThanOrEqual(1)` assertions with exact `toBe(N)`
counts. IMPORTS counts reflect per-symbol scope-based edges (value imports
only; `import type` is not emitted as an IMPORTS edge). CALLS counts are
1 per single-call-site.

* 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`.

* 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.

* 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.

* 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.

## P0 abhigyanpatwari#1 — missing scope-resolution hooks in vueProvider
`pass3CollectImports` early-returns when `interpretImport` is undefined,
producing zero IMPORTS and zero cross-file CALLS edges. Add the four
hooks to `vueProvider` in `vue.ts`:
  - `interpretImport: interpretTsImport`
  - `interpretTypeBinding: interpretTsTypeBinding`
  - `bindingScopeFor: tsBindingScopeFor`
  - `importOwningScope: tsImportOwningScope`
Also add `receiverBinding`, `mergeBindings`, `arityCompatibility`, and
`resolveImportTarget` to complete the scope-resolution contract.

## P0 abhigyanpatwari#2 — template-component CALLS dropped when Vue is registry-primary
`isRegistryPrimary(Vue) → true` makes the main call-processor loop skip
Vue files entirely, silencing the inline `vue-template-component` CALLS
emitter at ≈L1506. Add a dedicated post-loop pass in `call-processor.ts`
that emits template-component CALLS for Vue files whenever Vue is
registry-primary. Update the stale `vue/index.ts` limitation comment to
reflect the new emit site.

## P1 abhigyanpatwari#3 — worker-mode double-extraction → zero captures
In worker mode (≥15 files) the parse worker pre-extracts the `<script>`
block and passes `scriptContent` as `sourceText`. `emitVueScopeCaptures`
was calling `extractVueScript` a second time, getting null, and returning
`[]`. Fix: if extraction returns null and the content has no SFC block-
level markers (`<template`, `<style`), treat it as already-extracted
script text and delegate directly to `emitTsScopeCaptures`.

## Test assertion strictness
Replace all `toBeGreaterThanOrEqual(1)` assertions with exact `toBe(N)`
counts. IMPORTS counts reflect per-symbol scope-based edges (value imports
only; `import type` is not emitted as an IMPORTS edge). CALLS counts are
1 per single-call-site.

…closes #940) (#1950)

* feat(vue): migrate Vue SFC to scope-based resolution (RFC #909 Ring 3, closes #940)

Adds `vueScopeResolver` and wires Vue into the scope-resolution pipeline
(`SCOPE_RESOLVERS`, `MIGRATED_LANGUAGES`). Vue's `<script>` / `<script
setup>` blocks are TypeScript — `emitVueScopeCaptures` extracts the script
block via the existing `extractVueScript` utility and delegates to
`emitTsScopeCaptures`, keeping grammar identity consistent with the cached
tree the parse-worker already builds.

- `languages/vue/captures.ts`     — `emitVueScopeCaptures`
- `languages/vue/import-target.ts` — `makeVueResolveImportTarget` (TS
  resolver + tsconfig path-alias support; explicit `.vue` imports
  resolve via the exact-path branch)
- `languages/vue/scope-resolver.ts` — `vueScopeResolver`
- `languages/vue/index.ts`         — barrel + known-limitations doc

- `languages/vue.ts`                  — `emitScopeCaptures` hooked up
- `scope-resolution/pipeline/registry.ts` — Vue entry added
- `registry-primary-flag.ts`          — `SupportedLanguages.Vue` added
  to `MIGRATED_LANGUAGES` (production default → registry-primary)

- `vue-composition-api` — `<script setup lang="ts">`, defineProps /
  defineEmits macros, cross-file TS imports, computed refs
- `vue-options-api`     — `defineComponent({methods, computed, data})`,
  this-based method calls, imported utility calls
- `vue-cross-file`      — composable functions returning class instances,
  multi-level import chains, UserModel/PostModel method calls

- `fieldFallbackOnMethodLookup: true` — Options API `this.X()` calls may
  not resolve through the type-binding layer (no formal class); fallback
  catches common patterns via declared field names.
- `allowGlobalFreeCallFallback: false` — Vue uses explicit imports;
  workspace-wide unique-name fallback would produce spurious edges for
  built-ins (ref, reactive, defineProps, …).
- Template expression calls intentionally out of scope: component-
  reference CALLS edges are already emitted by the legacy template
  extractor. Remaining template gaps tracked in #1647.

* fix(vue): address P0/P1 review findings from #1950

* feat(vue): template-derived edges + pipeline benchmark (#1950 review)

Addresses the reviewer's request for template edge attribution and a
performance benchmark.

## Template event-handler CALLS (`vue-template-callback`)
Add `extractTemplateEventHandlers` to `vue-sfc-extractor.ts`. Extracts
bare single-identifier handlers from `@event="methodName"` and
`v-on:event="methodName"` attributes. Inline expressions with arguments
or operators (`@click="toggle(item)"`) are intentionally excluded.

Wire into the dedicated registry-primary Vue template pass in
`call-processor.ts`. For each extracted handler name, `ctx.resolve`
finds the in-file Function/Method node and emits a CALLS edge with
`reason: 'vue-template-callback'`.

## Template attribute-binding ACCESSES (`vue-template-attribute`)
Add `extractTemplateAttributeBindings` to `vue-sfc-extractor.ts`.
Extracts bare single-identifier values from `:prop="varName"` and
`v-bind:prop="varName"` bindings. Member-access (`:key="post.id"`) and
literals are excluded by the identifier-boundary regex.

Wire into the same template pass. For each extracted variable, `ctx.resolve`
finds the in-file node and emits an ACCESSES edge with
`reason: 'vue-template-attribute'`.

## `vue/index.ts` limitations comment
Updated to accurately describe all three categories of template-derived
edges and explicitly document the complex-expression exclusions.

## Tests
Add 6 new assertions in `vue-scope.test.ts`:
- `@click="handleSave"` → CALLS `handleSave` (UserProfile.vue)
- `@select="onPostSelected"` → CALLS `onPostSelected` (App.vue composition)
- `@keyup.enter="addTodo"` → CALLS `addTodo` (TodoList.vue)
- `@loaded="onUserLoaded"` → CALLS `onUserLoaded` (App.vue cross-file)
- `:userId="currentUserId"` → ACCESSES `currentUserId` (App.vue composition)
- `:posts="allPosts"` → ACCESSES `allPosts` (App.vue composition)

Add `vue` entry to `LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES` in
`helpers.ts` documenting which assertions are registry-primary-only
(IMPORTS cardinality, template-derived edges, `<script setup>` export).

## Benchmark
Add `vue-pipeline-benchmark.test.ts` (gated by `GITNEXUS_BENCH=1`).
Generates N-component synthetic repos (10 / 25 / 50 / 100) and asserts
that wall-clock and node counts scale sub-quadratically with component
count, guarding against O(n²) regressions in the template extraction
or scope-resolution passes.

* feat(vue): BINDS_EVENT_HANDLER/EMITS_EVENT edges via ScopeResolver hook

Per maintainer feedback on PR #1950:
- Do not edit call-processor.ts (will be removed when all languages migrate)
- Model Vue component-event system with dedicated edge types to avoid CALLS
  noise in deep component hierarchies (per contributor discussion)

Changes:
- gitnexus-shared: add BINDS_EVENT_HANDLER and EMITS_EVENT to RelationshipType
- vue-sfc-extractor: add extractComponentEventBindings, extractNativeElementEventHandlers,
  and extractScriptEmitCalls
- ScopeResolver contract: add optional emitPostResolutionEdges hook
- run.ts: wire emitPostResolutionEdges after emitImportEdges
- vue/scope-resolver: implement emitPostResolutionEdges emitting:
    1. CALLS (vue-template-component) — PascalCase component File refs
    2. CALLS (vue-template-callback) — @event on native HTML elements
    3. BINDS_EVENT_HANDLER (vue-event: @name) — @event on component elements;
       source = handler fn in parent, target = child component File (not CALLS)
    4. EMITS_EVENT (vue-emit: name) — emit() calls; self-loop on component File,
       joinable with BINDS_EVENT_HANDLER via Cypher for impact tracing
    5. ACCESSES (vue-template-attribute) — :prop="var" bindings
- call-processor.ts: revert dedicated Vue post-loop pass; moved to scope resolver
- Tests and parity expected-failures updated accordingly

* fix(vue): close review gaps in scope/parity extraction

Resolve the new PR #1950 review findings by widening Vue scope context to include TS/JS import closures, fixing BINDS_EVENT_HANDLER endpoint assertions, hardening emit/event extraction to avoid comment/property false positives, supporting kebab-case component tags, and ensuring parity runs include vue-scope suites.

* fix(vue): address second review round — regex safety, emit coverage, arch

Closes items raised in the Jun 2 review comment on PR #1950.

Correctness fixes:
- ReDoS mitigation: bound attribute-capture spans to [^>]{0,512}? in all
  three template tag regexes to prevent pathological backtracking.
- Kebab-case misclassified as native: added (?![A-Za-z0-9-]) negative
  lookahead to NATIVE_TAG_RE so <post-list> is no longer split as native
  tag `post` with attrs `-list ...`.
- Hyphenated event names dropped: widened TAG_EVENT_RE from [\w:.]+ to
  [\w:.-]+ so @user-loaded and @update:model-value are captured.
- this.$emit silently dropped: collectBareEmitEventNames now allows
  this.$emit(...) by looking back past the '.' to verify preceding token
  is exactly `this`; socket.emit etc. remain blocked.
- Event names with colon rejected: extended validator to accept
  update:modelValue and update:model-value patterns.

Architecture fix:
- Moved collectVueScopeFilePaths out of shared phase.ts into a new
  collectScopeContextPaths optional hook on ScopeResolver, keeping shared
  pipeline code language-agnostic. vueScopeResolver implements the hook.
- Fixed memory leak: preExtractedByPath cleanup now iterates filePaths
  (all context files) not just primaryFilePaths (only .vue files).

Cleanup:
- Removed unused extractTemplateEventHandlers and duplicate EVENT_HANDLER_RE.
- Fixed skipped comment numbers in emitPostResolutionEdges (1,2,4,5,6 -> 1-6).
- Updated vue/index.ts: four categories -> five (added EMITS_EVENT).
- Fixed gitnexus-shared EMITS_EVENT JSDoc to reflect File->File reality.

Tests: 7 new unit tests covering hyphenated events, this.$emit, kebab-case
native-tag exclusion, and update:modelValue event name validation.

* fix(vue): eliminate double file-read and per-file template re-scans

Two performance fixes from the self-review pass:

1. **No more double read of .vue files in phase.ts**: primary files were
   previously read once for `collectScopeContextPaths` (via
   `entryFileContents`) and again in the blanket `readFileContents(filePaths)`
   call. Now the primary-file map is passed directly and only the extra
   context files (TS/JS import closure) require a second I/O round-trip.

2. **Single template parse per .vue file in emitPostResolutionEdges**:
   previously each of the five extractor functions (components, native
   handlers, component event bindings, emit calls, attribute bindings) ran
   `TEMPLATE_RE.exec(content)` independently — five full-file scans per
   `.vue` file. Replaced with a new `extractVueTemplateEdgeData` batching
   helper that parses the template and script blocks once and feeds all five
   extractors from the pre-extracted content. emitPostResolutionEdges now
   calls a single function and destructures the results.

* fix(parity): exclude TypeScript HOC/HOF/JSX scope-resolver tests from legacy DAG parity gate

Three test files introduced in prior PRs exercise scope-resolver-only
correctness wins: HOC-wrapped const declarations, HOF-callback caller
attribution, and JSX-as-call CALLS edges. The parity runner's
${slug}-*.test.ts glob now picks them up, causing typescript [legacy]
failures in CI.

Fix: convert each file to use createResolverParityIt('typescript') and
register all 26 legacy-failing test names in
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.typescript with explanatory
comments. Legacy mode: 11+11+4 tests skipped, zero failures.
Registry-primary mode: all 37 tests pass as before.

* chore(test): remove registry-primary-flag unit tests after migration complete

All languages are now in MIGRATED_LANGUAGES; the per-language flip
tests are no longer needed. Addresses PR #1950 review feedback.
