📄 Description

Summary

Fixes #1781. analyze-javascript-application cut a //# or //@ sourceMappingURL at the first *. For //# sourceMappingURL=app*part.js.map it recorded declared_url: "app" and linked an unavailable reference instead of the inventoried app*part.js.map.

Problem and expected behavior

addSourceMapDirectives ended every directive URL at /[\s*]/u. Stopping at * is only needed so a block-comment URL ends before */. A line comment has no closing delimiter, and ECMA-426 MatchSourceMapURL takes the URL as a run of non-whitespace. Expected: the full declared URL, available: true, and a maps_to edge to the inventoried map.

Change and scope

Line comments (comment.type === "CommentLine") now end the URL at whitespace only. Block comments keep the existing [\s*] boundary. URL resolution is not touched (percent-encoded local paths are #1782).

Contract and boundary impact

  • Semantic owner and earliest changed stage: source-map directive extraction in src/domain/javascript/javascriptStaticAnalysisCalls.ts.
  • CLI and MCP/tool-catalog contract: none; existing fields carry the corrected value.
  • Provider, bridge, target-format, or platform compatibility: none.
  • Evidence, artifact, provenance, or reconstruction contract: declared_url, its digest and source range now cover the whole line-comment URL.
  • Process execution, authorization, cleanup, or containment impact: none.
  • Generated metadata, package, or installation impact: none.

Evidence and regression coverage

  • Tests added or updated:
    • src/domain/javascript/javascriptStaticAnalysisSourceMaps.test.ts: //# and //@ line comments containing *.
    • tests/boundary/filesystem/javascriptSourceMapComments.test.ts: reconstruction of a directory with a real app*part.js.map for both markers. Asserts a single source-map node, the full declared_url, available: true, the maps_to target and its source range.
  • Base reproduction: on 85ccef34 all four new cases fail (declared_url is app, two source-map nodes). They pass with this change.
  • User-visible CLI output (built CLI, issue fixture, --max-heap-mb 512 --json), source-map reference observation:
    • before: {"declared_url":"app","resolved_path":"app.js","available":false}
    • after: {"declared_url":"app*part.js.map","resolved_path":"app*part.js.map","available":true}
    • same result for //@; block-comment control /*# sourceMappingURL=app.js.map*/ still resolves app.js.map.
  • Remaining proof gaps: * is not a valid Windows filename, so the boundary fixture only runs on Linux/macOS. These files are not in the Windows curated lane.

For evidence-bearing changes:

  • Observed, derived, and inferred claims remain distinguishable.
  • Artifact identity, source provenance, and failed attempts remain preserved.
  • Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Validation performed

Linux x64, Node 24.18.0, npm 11.16.0:

  • npm run test:focused -- all src/domain/javascript/*.test.ts plus tests/boundary/filesystem/javascriptSourceMapComments.test.ts tests/boundary/filesystem/javascriptSourceMapLocations.test.ts tests/boundary/filesystem/sourceToBundlePaths.test.ts tests/boundary/filesystem/javascriptArtifactGraphObservationLookup.test.ts src/application/javascript/JavaScriptApplicationEmptyLiterals.test.ts: 48 files, 904 tests passed.
  • npm run check: passed (0 lint errors, warning count unchanged from main; architecture guards passed).
  • npm run verify:test-discovery: passed.
  • npm run build:cached, then node scripts/rea.mjs analyze-javascript-application <fixture> --max-heap-mb 512 --json for //#, //@ and the block-comment control: output above.
  • git diff --check: passed.

Compatibility, safety, and release

  • Breaking changes or migration steps: none.
  • Real Hopper/Ghidra, browser, or OS coverage: not applicable; Linux only.
  • Package or release metadata impact: none.
  • Security, privacy, process, or containment review: no new file access; the longer URL still goes through the existing confined resolver.

Review checklist

  • This PR addresses a concrete problem or an agreed enhancement.
  • The PR has one focused outcome and the title follows type(scope): outcome.
  • Related issue is linked, or the reason for not linking one is stated above.
  • Tests cover changed observable behavior and meaningful failure paths.
  • Owning docs, contracts, and generated metadata are updated where needed.
  • User-visible CLI/MCP changes include representative output.
  • I checked the final diff for secrets, unrelated cleanup, and unsupported claims.
