# Prompt Audit implementation evidence

This file records reproducible implementation-time evidence. It contains no prompt bodies, Guard credentials, Authorization values, or Redis payloads.

## 2026-07-16 — source freeze and target baseline

### Frozen source restore

- Base commit: `7a50378851a80650cb0c086260b23abeb3469e6b`
- Freeze manifest: `source-freeze/MANIFEST.md`
- Manifest SHA-256: `badab312bf6af4d2c77857a9400381f4da4fbf45722d9f4a6df23bc7005273b6`
- Restore result: tracked patch and untracked archive restored into a detached worktree; `git diff --check` passed.
- `go test ./internal/service/promptaudit -count=1`: passed.
- `go test ./internal/router ./internal/relay ./internal/gatewayadapter/transport -run 'PromptGuard|PromptAudit|ConcurrencyOrder' -count=1`: passed.

### Target pre-change baseline

- `cd backend && go test ./internal/service -run ContentModeration -count=1`: passed (`1.138s`).
- `pnpm --dir frontend exec vitest run src/views/admin/__tests__/RiskControlView.spec.ts src/router/__tests__/feature-access.spec.ts`: passed (2 files, 9 tests).

### Review slices

Implementation is partitioned into independently reviewable slices without changing the final scope:

1. Data and core contracts.
2. Async audit engine.
3. Admin API and console.
4. Coordinator and synchronous guard.
5. Observability, verification, rollout, and deployment evidence.

The feature remains default-off throughout implementation. Production blocking remains prohibited until the signed rollout gates in `verification.md` are satisfied.
