This directory is a cockpit, not an archive.
If someone clones this repo and reads only /docs/status, they should know —
in under 5 minutes — exactly what is safe, what is experimental, and what is drifting.
Narrative documents, temporal plans, and time-bound reports live in docs/records/.
- DCP / verified deterministic surface means the surface is inside the deterministic-core boundary and backed by registry/enforcement evidence.
- Governed non-DCP means the surface is policy-bounded and important, but not entitled to full deterministic-surface claims.
- Experimental / non-DCP means the surface is outside release-grade deterministic guarantees unless later promoted.
| Question | Document |
|---|---|
| What is frozen? | FROZEN_CORE_PROFILE.md |
| What is drifting? | DRIFT_DECOMPOSITION.md |
| What is risky? | ACTIVE_RISKS.md |
| What is blocked / being hardened? | HARDENING_BACKLOG.md |
| What is governed non-DCP or experimental? | EXTENSION_PROFILE.md |
| What is the review protocol? | GOVERNANCE_REVIEW_CADENCE.md |
PROJECT_CONTROL_CENTER.md— phase, health, gates, drift summary, top risks, next decisions, and deterministic-surface classification
FROZEN_CORE_PROFILE.md— directory boundary, opcode whitelist, DCP guarantees, exclusions, firewall
IMPLEMENTATION_MATRIX.md— spec authority, implementation maturity, promotion state, drift risk, last review date per subsystemAI_CLI_IMPLEMENTATION_MATRIX.md— concrete reality check fort81 ai ...; distinguishes real surfaces from scaffolded or stubbed inference commands
ACTIVE_RISKS.md— short risk table; refreshed weeklyDECISION_LOG.md— what was decided, by whom, when, alternatives considered
DRIFT_DECOMPOSITION.md— spec claim → implementation reality → closure plan, per surfaceHARDENING_BACKLOG.md— structural hardening and determinism tightening only (no features)DETERMINISM_AUDIT_LOG.md— chronological: what was audited, what failed, what was patched, what remains open
EXTENSION_PROFILE.md— governed non-DCP and experimental surfaces; what is not frozen, what can break, what has no DCP guaranteeAI_RFC_BACKLOG.md— prioritized AI RFC execution order, ownership, dependencies, and compliance snapshot
GOVERNANCE_REVIEW_CADENCE.md— monthly review checklist, drift protocol, registry update procedure, promotion gate
CI_GATE_STATUS.md— required gates, informational gates, known failures, benchmark guardrail, flaky-test inventoryDEPENDENCY_HEALTH.md— dependency versions, upgrade policy, CVE tracking, determinism impactTASKS.md— active implementation tasks (C2 close, stdlib fixture suites)AI_CLI_MILESTONE_EVIDENCE.md— current bounded native AI inference milestone snapshot, runnable proof points, and remaining gap
