 | Future B1–B6 | 💤 vision | `CASAN_PLAN_FUTURE_PHASES.md` — approval workflow nâng cao · state machine · model benchmark · governed memory · auto-remediation · platform KPI. |
 | **17 Loop Engineering** | � T1–T6 done+test (offline) | **Agentic Loop Governance** — đủ 5 primitive + orchestrator (97/0 WSL, nối CI). T1 **Governor** (`loop-governor.py`; deny-by-default, no/corrupt policy→strict/HALT, on_exceed halt/escalate) 15/0; T2 **Convergence** (`loop-convergence.py`; repeat/thrash→OSCILLATING, flat→STALLED, fail-closed) 15/0; T3 **Verify Contract** (`loop-gate.py`; H4→DENY, unmet→FAIL, correction bounded→ESCALATE, no self-declared DONE) 20/0; T4 **Trace/Replay** (`loop-trace.py`; append-only hash-linked, edited→BREAK, tampered artifact→replay DRIFT) 16/0; T5 **Meta-loop** (`loop-metaloop.py`; propose≠apply, SoD, loosen>org_ceiling refused, apply qua governed CP store→đổi thật ceiling + rollback) 15/0; T6 **Orchestrator** (`loop-run.sh`; gate→governor→convergence→trace/turn, secure-by-default opt-out, nén giữa vòng) 16/0. State qua `CASAN_LOOP_STATE_ROOT` (repo `.specify/state` sạch). **Còn (infra):** T4 KMS-anchor head (A7 Vault), T6 widget Command Center (17.22, C5), live H3-judge.
