This repository is public, and published git text is not reliably retractable. This adds a fast local guard so a configured term cannot reach a commit message, a staged path, or an added line. - `scripts/git_hooks/commit-msg` scans the commit message. - `scripts/git_hooks/pre-commit` scans staged paths and added lines. - `scripts/git_hooks/leak_guard.py` is the shared scanner. - `scripts/install-git-hooks.sh` points `core.hooksPath` at the tracked directory, so the guard is version-controlled and shared rather than living untracked in `.git/hooks`. Run once per clone. Terms are stored as SHA-256 hashes in `blocked-terms.sha256`, never as plaintext: a readable denylist in a public repo would defeat its own purpose. Hashing resists casual grep and search indexing; it is not meant to withstand a dictionary attack. `--add-term` prompts for the term instead of taking argv, so it never lands in shell history. Matching is on whole alphanumeric tokens of the lowercased text, which covers the realistic shapes (prose, paths, `org/repo#123`, CamelCase run together) while a term buried mid-word is deliberately out of scope, to keep false positives near zero. The guard is regex-only and instant. It does not run tests -- that stays the agent's responsibility, per the existing policy, and CLAUDE.md is updated so the note about hooks stays accurate. Hooks cannot see PR bodies or issue comments, since those never pass through git. `leak_guard.py --stdin` is provided so that prose can be checked before it is published. Verified: blocks a configured term in a commit message and in a staged file, passes clean text, does not false-positive on similar-looking words, and `--no-verify` still bypasses.
