Checkpoint — Phase 2 Execution Substrate & Offline MVP Path

Date: 2026-06-10 · Final status: APPROVED_CI_OR_OPERATOR_PACKET_READY (terminal state B) Production mutation: NO · Codex: NO · Mac-local evidence: NO · Article 13: PASS · Article 14: PASS

Scope

Program macro: close the entire Phase 2 execution substrate + offline-MVP path end-to-end, or leave only a true operator/authority blocker. Read-only except KB document writes (the 7 deliverables below). No install, no container run, no prod mutation, no external publish.

Track outcomes

Track	Outcome
T1 KB readback	PASS — 14 docs read in full (via subagent digest); statuses consistent; no blocking contradiction; index rev82
T2 Substrate inventory	DONE — 10 surfaces matrixed; no agent-runnable approved substrate; S7 CI + S9 operator triggerable
T3 Route decision	DONE — Route 2 CI primary, Route 3 operator fallback; Routes 1/4/5 rejected with evidence
T4 Direct VPS run	NOT RUN — VPS Docker socket read-only by design; no run/create/exec
T5 CI packet	DELIVERED — workflow + 12-probe harness + §7 emitter + packet
T6 Operator packet	DELIVERED — consolidated final, references 06-09 SSOT
T7 Build MVP	NOT BUILT (gated) — prohibited until B4′ PASS
T8 Acceptance/negative tests	NOT RUN — L1 tests need attested sandbox
T9 FIX7 read/report fixture	NOT RUN — part of gated MVP
T11 Cleanup	N/A — nothing disposable created
T12 Article 13	PASS
T13 Article 14	PASS

Fresh evidence (2026-06-10)

• VPS list_docker: 11 containers up; socket read-only by design; no run/create/exec/shell tool.
• Local gh auth status: authenticated Huyen1974, scopes incl. workflow,repo,admin:org. /Users/nmhuyen not a git repo; no tool-kiem-thu project repo.

Key advance

Blocker reclassified missing host Docker → missing authorized execution substrate/trigger. CI route found reachable and made turnkey; the action collapses to a single owner venue-authorization + trigger.

• 00-index.md patched (rev82 → rev83).

Intentionally absent (no fake-green): B4′ attestation evidence (not run), MVP execution report/JSON/matrix-binding/raw-log (MVP gated).

Remaining blocker

B4_PRIME_AUTHORIZATION_AND_EXECUTION_REQUIRED — owner authorizes one venue (CI-A/CI-B/operator); human/CI runs it; returns §7 bundle; follow-up agent verifies read-only vs matrix #24–#37; then run gated build prompt.
