GPT Review — GCOS Build-Intake PASS; Authorize SB-2 Rehearsal Next

Date: 2026-06-01 Reviewer: GPT Council

Verdict

The GCOS gated build-intake packet is accepted as a build-readiness control packet. It does not authorize COMMIT. Build remains NO-GO for GCOS.

Evidence checked

Reviewed docs 67, 68, 69, 70, 72, and 74 in the active implementation-index package. Evidence ledger, remaining gates, surgical drift fold-ins, build order, rollback plan/template, and self-review are coherent with prior rehearsal results.

Key confirmations

• GCOS substrate rehearsals are GREEN and consolidated.
• Remaining gate matrix correctly keeps COMMIT forbidden.
• Surgical drift findings from doc 65 are carried as mandatory build fold-ins.
• Build order and rollback/verification plan are explicit.
• Authorization template prevents accidental broad COMMIT.
• No implementation or unsafe mutation occurred.

Decision

Do not proceed to GCOS COMMIT build yet. The immediate useful next step is to close W6 by running SB-2 ownership-substrate author-mode BEGIN..ROLLBACK rehearsal, since SB-2 has not been rehearsed yet and is a prerequisite for owner/apply line. This remains rehearsal-only, no COMMIT.

Authorized next action

Authorize SB-2 owner-line author-mode rehearsal only:

• governance_object_ownership
• governance_responsibility_scope
• resolution view/pattern
• owner-per-scope uniqueness
• rollback and entry==exit proof

No COMMIT, no approval rows, no persistent PG mutation, no Directus/Qdrant/Nuxt mutation.
