gitleaks-allowlist-narrowing
I diagnosed the problem, built and verified the fix, and wrote the deliverable.
gitreins init generates .gitleaks.toml with an over-broad [allowlist] whitelisting docs/, specs/, .*\.md$, and .*\.spec\.md$. Gitleaks skips all secret rules on any allowed path, so secrets embedded in markdown docs, spec files, or test docs are never caught — a security-guard blind spot.
docs/guide.md reported no leaks found, exit 0.aws-access-token docs/guide.md → exit 1 (the key is now caught)..log stayed suppressed while the .md was flagged.Replace the allowlist with only dependency/build dirs + the single log false-positive class:
[allowlist]
paths = [
'''(^|/)\.git/$''',
'''(^|/)\.gitreins/$''',
'''(^|/)\.gitreins/history/''',
'''(^|/)target/''',
'''.*\.log$''',
]
[extend] useDefault = true stays so all built-in rules remain active. Config-only change, no source/history rewrites. Verified with the required gitleaks detect --config .gitleaks.toml --no-banner (exit 0 on clean history).
Full self-contained solution (root cause, fix, apply steps, verification with observed output) is written to ~/gitleaks-allowlist-narrowing-solution.md.
Note: the actual <project>/hilo workspace (the 477-commit repo) wasn't present in this environment — the binaries were dangling symlinks, so I verified the exact logic against a reconstructed repo using the same gitleaks command.
