The full documented flow verifies end-to-end. Here's the summary.

Solution delivered

I diagnosed the problem by extracting the gitreins source and reproducing the exact failure, then fixing and re-verifying it. The writeup is in ~/SOLUTION.md.

Root cause (what I actually found)

The failing step is not gitleaks git. gitreins' pipeline secrets step (engine/pipeline.py, DF-012) runs the built-in _builtin_secrets_scan(staged_only=False), which:

Traverses the entire workdir with os.walk() — including untracked files, and .coding-hermes isn't in its skip_dirs. (It never consults .gitignore, so ignoring the dir doesn't help.)
Reads each file as text with errors="replace" and line-scans it against regex danger_patterns (e.g. AWS AKIA[0-9A-Z]{16}).
A SQLite page read as text exposes an embedded task-ID/secret-looking bytes surrounded by binary — so gitreins re-prints the raw bytes as the "binary garbage" finding.

gitleaks git stays clean because it scans committed history, and gitleaks itself skips binary .db files. The built-in text scanner is the trip.

Fix (exactly as billed)

Add the cache dir to .gitleaks.toml [allowlist].paths — gitreins' built-in scanner intentionally parses every '''...''' string there as a regex and skips matching file paths (and gitleaks honors the same allowlist):

[allowlist]
paths = [ '''\.coding-hermes/board/''', ]

Verified

In a throwaway repo with an untracked board.db:

step	result
guard scan before fix	`PASSED: False` — `board.db [AWS access key] <raw binary bytes>` (reproduced)
after adding allowlist	allowlist parsed → `PASSED: True` — "Scanned 3 files — clean"
gitleaks w/ same config	clean (allowlist applied)

The repo state I used for verification was /tmp/repro and /tmp/verify; the gitleaks 8.30.1 binary is at /tmp/gitleaks.
