+# PR #3788: feat(B-0557 slice 2): try/catch readFileSync + readdirSync in audit tool
+
+## PR description
+
+## Summary
+
+- Addresses Copilot P1 finding from PR #3758: `enumerateOpenRows()` could throw and abort the whole audit on a single unreadable backlog file (permission denied, transient FS error, etc.).
+- Fix: wrap both `readdirSync` and `readFileSync` in try/catch; warn to stderr; continue with remaining files.
+- Bundles peer Otto-Desktop's tick shard `10fb6e5` (brief-ack extreme cost-aware tier substrate).
+
+## Test plan
+
+- [x] `bun test tools/hygiene/audit-backlog-status-drift.test.ts` → 16 pass / 0 fail / 28 expect calls (no regression)
+- [x] `bun tools/hygiene/audit-backlog-status-drift.ts --json` still produces 33+ candidates from main
+- [x] Stderr warnings clearly name the failed file(s) when triggered
+
+## Composes with

+
+## Pull request overview
+
+Improves the resilience of the `audit-backlog-status-drift` hygiene tool by preventing filesystem read errors from aborting the entire audit run, and adds a new hygiene-history tick shard documenting related operational context.
+
+**Changes:**
+- Wraps `readdirSync` and `readFileSync` in `try/catch` inside `enumerateOpenRows()` to warn-and-continue on unreadable directories/files.
+- Emits stderr warnings with the directory/file path and error message when reads fail.
+- Adds a new `docs/hygiene-history/ticks/...` shard documenting the session tick.

+**@copilot-pull-request-reviewer** (2026-05-16T06:52:02Z):
+
+`err` is typed as `unknown` here, but the message formatting casts to `Error` (`(err as Error).message`). This can print `undefined` (or miss useful info) for non-`Error` throws. Prefer the repo’s existing pattern: `err instanceof Error ? err.message : String(err)` (optionally include `code` when present).

+This issue also appears on line 210 of the same file.

+
+**@copilot-pull-request-reviewer** (2026-05-16T06:52:03Z):
+
+This tick shard doesn’t follow the documented shard schema: `docs/hygiene-history/ticks/README.md` requires the first non-empty line to be a single-row `| <ISO timestamp> | ... |` table entry. Starting with an `# Tick ...` heading will fail existing shard validators/parsers that look at the first non-empty line. Consider adding the required pipe-row as the first line (and keep the prose below), or update the schema/tooling in the same PR if the format change is intentional.

+# PR #3790: feat(B-0557 slice 3): chdir to repo root via git rev-parse (cwd-independent)
+
+## PR description
+
+## Summary
+
+- Adds `process.chdir(detectRepoRoot())` at the start of `main()` in the audit tool.
+- `detectRepoRoot()` invokes `git rev-parse --show-toplevel` and falls back to `process.cwd()` if git is unavailable or the tool runs outside a repo.
+- Per Copilot P1 on PR #3758 ([B-0557](docs/backlog/P3/B-0557-audit-backlog-status-drift-quality-improvements-2026-05-16.md) slice 3).
+
+## Test plan
+
+- [x] 16/16 existing tests pass (no regression)
+- [x] Smoke from `/tmp` returns honest `[]` (correctly handles outside-repo case)
+- [ ] Smoke from a subdir of the repo (e.g., `cd docs && bun ../tools/...`) — should now produce same 33+ candidate output as from root (would be regression-test material in follow-up)
+
+## Known limitation (follow-up candidate)
+
+If invoked from outside any git repo, `git rev-parse` errors and the fallback `process.cwd()` doesn't locate the Zeta repo. A future iteration could use `import.meta.dir` to derive repo root from the tool's own file location (making truly cwd-independent — works from any cwd including non-repo dirs).

+## Pull request overview
+
+This PR makes the backlog status-drift audit tool work from repository subdirectories by detecting the Git repo root and changing the process cwd before relative path checks run.
+
+**Changes:**
+- Adds `detectRepoRoot()` using `git rev-parse --show-toplevel` with a cwd fallback.
+- Calls `process.chdir(detectRepoRoot())` at the start of `main()`.
+- Preserves existing argument parsing and reporting behavior after cwd normalization.

+### Thread 1: tools/hygiene/audit-backlog-status-drift.ts:269 (resolved)
+
+**@copilot-pull-request-reviewer** (2026-05-16T07:01:50Z):
+
+P1: The cwd-independent behavior is now implemented only through `main()` and `detectRepoRoot()`, but neither is exported or exercised by the existing test suite. The linked test file covers parsing and candidate filtering, so this regression (invoking from a repo subdirectory and getting the same results as repo root) can slip again without a smoke/unit test that runs the CLI from a subdirectory.
+
+### Thread 2: tools/hygiene/audit-backlog-status-drift.ts:50 (resolved)
+
+**@copilot-pull-request-reviewer** (2026-05-16T07:01:51Z):
+
+P2: This current-state tool comment embeds PR-review provenance (`Copilot P1 on PR #3758`) in source code. The repository guidance keeps historical attribution in backlog/PR-history surfaces and asks reusable code comments to describe the current invariant instead; the B-0557 reference is enough context without the reviewer attribution.
+
+### Thread 3: tools/hygiene/audit-backlog-status-drift.ts:56 (unresolved)
+
+**@chatgpt-codex-connector** (2026-05-16T07:22:48Z):
+
+**<sub><sub>![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)</sub></sub>  Silence git stderr in repo-root detection fallback**
+
+When this tool is invoked from a directory that is not a Git worktree, `execFileSync("git", ["rev-parse", "--show-toplevel"])` throws as expected, but Git’s fatal message is still emitted to stderr before the catch fallback runs. That means a successful run can now produce unexpected stderr noise (including in `--json` mode), which can break automation that treats any stderr output as a failed check. This behavior is introduced by the new root-detection path and should be suppressed when the fallback path is intentional.
