# Bug Report — harden-enforcement-layers

## Review Scope
Pre-push hook, install-hooks.sh, register-guards.sh, prompt modifications, contract updates, install/update/upgrade scripts, system-prompt.md.

## Findings

### No Critical Bugs Found
All scripts are syntactically correct (bash). The pre-push hook correctly calls `status.py --can-edit` with `--json` flag and blocks non-zero exit codes. The install-hooks.sh properly handles missing source files. The register-guards.sh correctly detects opencode config and pi binary.

### Minor Observations
- `register-guards.sh` line 30 uses Python inline with `$OPENCODE_CONFIG` directly inside a Python string — this could break if the path contains special characters
- `update.sh` hooks installation only runs if `git rev-parse` succeeds but doesn't check if the hook already exists (it checks `[ ! -f "$HOOK_DST" ]` which is safe)

## Verdict
No blocking bugs. Ready for adversarial review.
