GPT Review — Final Pre-Code Bundle PASS; Engineering Ready, Needs Explicit Build Authorization

Date: 2026-06-01 Reviewer: GPT Council

Verdict

The final pre-code bundle is accepted. Engineering pre-code work is complete for the first build candidates. The system is not yet authorized to build because build authorization has not been explicitly granted.

Evidence checked

Reviewed docs 87, 88, 89, 91, and 92 in the active implementation-index package. The readiness matrix, blocker ledger, build handoff, and entry==exit verification are coherent with the final report. The handoff correctly says M-1 absence means COMMIT_FORBIDDEN.

Key confirmations

• SB-1, SB-2, SB-10, SB-11, SB-12, SB-13 are marked BUILD_READY_NEEDS_AUTH, not silently built.
• T6/T7/backfill/handoff/input remain BUILD_NO_GO until substrate build and fold-ins.
• OP-B/SB-3/L-1/L-2 remain FUTURE_LAW_OR_DESIGN.
• Entry==exit is proven; no residue remains.
• Final build handoff doc 89 is the correct future build entrypoint.
• Critical drift F-83-1 is correctly identified: SB-1 build must rewire birth trigger to use action_code before inserting APR action-type rows.

Decision

Conditionally authorize the next step as a narrow build-authorization preparation decision, not automatic build. GPT may decide whether to authorize the first actual build step if the user explicitly delegates build authority and the prompt is narrow, reversible, and starts from doc 89.

Recommended first build if authorized: SB-12 + SB-13 only, because they are prerequisite substrate and do not touch SB-1 trigger/birth complexity. Alternatively, SB-2 is also rehearsed-green, but SB-12/SB-13 are the cleanest foundation for GCOS.

Non-negotiable guardrails for build

• One build step per mission.
• Preflight live re-verify.
• pg_dump/rollback plan before COMMIT.
• Exact object list allowed.
• Stop if M-1/build authorization text is absent.
• No DOT/event registration or production behavior in the first build.
• No SB-1 build until F-83-1 trigger fix is included and verified.
