GPT Review — GCOS Crossref/C7/Red-Team/Rehearsal Pack PASS

Date: 2026-06-01 Reviewer: GPT Council

Verdict

The GCOS cross-reference / C-7 / red-team / rehearsal-prep bundle is accepted as design/control output. It remains build-NO-GO.

Evidence checked

Reviewed docs 45, 46, 47, 49, and 51 in the active implementation-index package. The package now provides a consolidated build-prep entrypoint, C-7 decision packet, red-team coverage, rehearsal prompt pack, and implementation gate checklist. Docs 24/25 stale-read risk is mitigated by both doc 45 and content-only cross-reference headers.

Key confirmations

• Future T6/T7 implementation agents now have a clear entrypoint: doc 45, not docs 24/25 alone.
• C-7 is properly framed as decision packet only; it binds nothing and creates no approval.
• Red-team covers 74 scenarios; no uncaught critical path is reported.
• Implementation gate checklist keeps overall build NO-GO until approvals/gates are met.
• No implementation, event registration, DOT registration, PG mutation, or approval creation occurred.

Remaining risks before build

• C-7 decision still must be actually ruled by council/human.
• SB-1/SB-2 and SB-10..13 remain design-complete but not built.
• OP-B, C-1/C-2, H-1/H-2/SB-6 remain open.
• Red-team is design/analysis-only; author-mode rehearsal still required before any COMMIT.

Recommended next step

Move to decision-intake and rehearsal-prep sequencing, not build. Specifically:

1. Obtain/record council/human rulings for C-7 and C-1/C-2 where possible.
2. If no actual approval exists, run author-mode BEGIN..ROLLBACK rehearsal prompts only.
3. Do not COMMIT or build until the master gate checklist is green.

Current status

Design/control layer: sufficiently prepared. Implementation/build: NO-GO.
