From 274f5917d49d2ca1b990cbad31e68fff1593e3c4 Mon Sep 17 00:00:00 2001 From: Aaron Stainback Date: Sat, 16 May 2026 02:53:30 -0400 Subject: [PATCH 1/2] =?UTF-8?q?feat(B-0557=20slice=203):=20chdir=20to=20re?= =?UTF-8?q?po=20root=20via=20git=20rev-parse=20=E2=80=94=20cwd-independent?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per Copilot P1 on PR #3758: tool previously assumed cwd = repo root. Running from a subdirectory caused all existsSync(p) checks to fail and produced false negatives. Fix: at main() start, detect repo root via git rev-parse --show-toplevel and chdir. All subsequent relative-path reads + existence-checks now work regardless of invocation cwd. Fallback: if git unavailable or not in a repo, retain cwd. Verified by smoke-testing from /tmp — tool produces the same 33+ candidate output as when run from repo root. 16/16 existing tests pass (no regression).

P1: detectRepoRoot() was internal-only; no test verified the cwd- independent behavior. Fix: export detectRepoRoot + add 2 tests (verifies repo root contains the tool itself + canonical top-level files like CLAUDE.md). 2. P2: Source comment embedded reviewer attribution ("Copilot P1 on PR #3758"). Repo guidance keeps historical attribution in backlog/ PR-history surfaces and asks reusable code comments to describe current invariants. Cleaned the docblock; preserved B-0557 ref. bun test → 18 pass / 0 fail (was 16; +2 for detectRepoRoot).
