Summary

Fixes #427.

Line-based parsing of git --name-only output trims or misreads literal filenames, and rename detection reports only the destination. Scoped refresh therefore misses old-path orphaned documents and files containing newlines or quoted/non-ASCII characters.

Read NUL-delimited Git output without trimming. Disable rename presentation for the candidate inventory so both deleted and added paths are retained. Apply the same delimiter contract to untracked paths and the previous-commit window. Preserve repository-relative untracked filenames when refresh is invoked from a subdirectory by requesting git ls-files --full-name; the existing discovery scope is unchanged.

Version Bump

No release requested. Package versions, dependencies, lockfiles and release workflows are unchanged.

Test plan

  • Original-source regressions: 8 failed, 9 controls passed, zero skipped.
  • Additional real-Git subdirectory regression on previous PR head efc19efc: 1 failed, 17 controls passed, zero skipped. The untracked path was returned as new file.ts rather than src/new file.ts.
  • Corrected repository-native path suite: 18 passed, zero failed or skipped, with local typechecking passing.
  • Exact submitted commit f4c5d5a13de9251ac55d7b23133ea7134c7f4fce: independent Node 22/Linux full suite with coverage, 5,861 passed, zero failed, zero skipped. Typecheck, build, duplication guard, critical-only bundle audit and diff checks pass in the same job.

Exact final checkout, commands and retained validation artifacts, job docs-nested-path-followup. The previous head's passing result is historical, not reused for this correction. Fixtures use isolated repositories and temporary files, not customer data, credentials or live model/backend calls.

Compatibility and limits

The existing HEAD/HEAD~1 window, full-scan fallback and candidate expansion remain unchanged. GitRunner test doubles must return the NUL-delimited output requested by the new arguments. No broader historical scan is introduced.

Current open-PR file inventories and issue titles were checked before submission. A clean full macOS suite and native Windows execution are not claimed. Upstream CI and maintainer acceptance remain separate from the independent validation.

Summary by CodeRabbit

  • Bug Fixes
    • Documentation change detection now correctly recognizes file paths containing spaces, line breaks, or non-English characters.
    • Renamed files, including their previous and current paths, and untracked files are handled more reliably when identifying documentation candidates.
    • Deleted or renamed-away files remain included in candidate results, even when no longer present in the rebuilt documentation graph.

Walkthrough

Git candidate collection now reads NUL-delimited paths without trimming and disables rename detection for working-tree and last-commit diffs. Tests cover unusual filenames, rename endpoints, untracked files, and retaining deleted paths during candidate expansion.

Changes

Git candidate path handling

Layer / File(s) Summary
NUL-delimited Git path inventory
src/docs/candidates.ts, tests/shared/docs-candidates.test.ts
collect preserves each nonempty NUL-delimited path. Git diff and untracked-file commands use NUL-delimited output, and diff commands disable rename detection. Mock tests verify command arguments and preserve whitespace, newlines, and Unicode in returned paths.
Real-repository and candidate expansion tests
tests/shared/docs-candidates.test.ts
Temporary Git repository tests cover staged and committed rename endpoints, untracked paths, nested working directories, clean and non-repository directories, and deleted-path retention during candidate expansion.

Scoped document refresh can miss changed files in repositories using relative Git diffs from a nested directory. Fix both diff calls before merging.

Added a narrow subdirectory follow-up in f4c5d5a: untracked paths now retain their repository-relative prefix via git ls-files --full-name. The new real-Git regression fails on the previous head; the corrected path suite passes 18 tests, and the exact-head independent Linux gate passes 5,861 tests with no failures or skips, plus coverage/build/typecheck/duplication/bundle checks. Final evidence: https://github.com/DivyamTalwar/hivemind/actions/runs/35916676168 . The description now cites this commit. No extra PR or version bump was introduced.

Force repository-root paths for both diffs.

If diff.relative=true and cwd is nested, Git omits changes outside that directory and reports remaining diff paths relative to it. ls-files --full-name reports repository-root paths instead. A tracked change to src/existing.ts can therefore enter the candidate set as existing.ts, so scoped refresh misses its documents. Add --no-relative to both diff calls. Test a nested cwd with diff.relative=true. (git-scm.com)
