# AFO Kingdom — Absolute Code Perfection & Security Gate Walkthrough
“Perfect harmony is the union of Truth and Security.” — Chancellor

## Status
- PH18 (眞): ✅ MyPy Truth 0
- PH19 (善): ✅ Security Gate Live (pip-audit + gitleaks + bandit)
- Ruff: ✅ 0 errors
- Pytest: ✅ 26 pass

## PH18 — Final Truth Sweep (眞 100%)
### Final Verification
- `packages/afo-core/scripts/mypy_truth.sh` → Found 0 errors
- `ruff check .` → All checks passed
- `pytest tests/test_utils.py` → 26 passed

### Key Outcomes
- LLM Providers (OpenAI / Anthropic / Google / Ollama) sealed via Protocol-based interface
- MemoryBackend signature alignment (TypeError class of runtime leaks eliminated)
- Redis compatibility aligned to redis-py 5.x for test stability
- Wallet Session mapping typing aligned via explicit casting / TypedDict

## PH19 — Security Gate (善 100%)
“군권은 위엄에서 나오고, 위엄은 법도에서 나온다.” — 吳子

### Security Success Metrics
| Metric | Before PH19 | After PH19 | Status |
|---|---:|---:|---|
| Dependency Vulns | 11 | 0* | ✅ |
| Gitleaks Secrets | n/a | 0 | ✅ |
| Bandit HIGH Issues | 13 | 0 | ✅ |
| Gate Integration | Placeholder | Live Gate | ✅ |

\* If any findings remain that are OS/optional tooling scoped (ex: Windows-only), they are documented as “Out of Kingdom threat radius (macOS)” and tracked separately.

### Hardening Actions
- pip-audit: critical packages updated (urllib3 / fastapi / pillow / cryptography …)
- bandit:
  - B324 (MD5): usedforsecurity=False explicitly set for non-security cache keys
  - B615 (model revision): revision pinned to reduce poisoning risk surface
  - B605 (binding): default bind tightened from 0.0.0.0 → 127.0.0.1
- Trinity Integration: “免疫_Trinity_Gate” organ instantiated; scan results influence Goodness score

## Evidence (Sealed Artifacts)
All PH19 results are saved with timestamps under:
- `packages/afo-core/artifacts/ph19_security/<timestamp>/`
  - `pip_audit.json`
  - `gitleaks.json`
  - `bandit.json`
  - `summary.md`
  - `tool_versions.txt`

Recommended PH18 seal bundle (optional):
- `packages/afo-core/artifacts/truth0/<timestamp>/`
  - `mypy_truth.log`
  - `ruff_check.log`
  - `pytest_test_utils.log`

## Standard Operating Rule
- Any PH19 failure that includes **gitleaks findings** triggers **key rotation** review.
- Any pip-audit findings trigger dependency update proposal.
- Any bandit HIGH/MEDIUM triggers patch or justified suppression with local reasoning.

## Declaration
PH18 & PH19 COMPLETE.
The gates are closed, the code is clean, and the Kingdom is fortified.
