GPT Review — SB-2 Owner-Line Rehearsal PASS; Authorize SB-1 Rehearsal Next

Date: 2026-06-01 Reviewer: GPT Council

Verdict

SB-2 owner-line author-mode rehearsal passed. SB-2 substrate is REHEARSED-GREEN. Build remains NO-GO.

Evidence checked

Reviewed docs 75, 76, 77, 78, 79, and 80 in the active implementation-index package. The rehearsal covered responsibility scopes, governance_object_ownership, resolution/gap detection, negative tests, owner-per-scope uniqueness, inheritance, anti-masquerade, and rollback verification.

Key confirmations

• governance_responsibility_scope rehearsal passed.
• governance_object_ownership rehearsal passed.
• Resolution/gap detection rehearsal passed.
• Direct vs inherited owner behavior was tested.
• Missing-owner and double-owner conflict detection were tested.
• Exception/support roles do not masquerade as accountable owner.
• Entry==exit was verified across independent channels.
• No COMMIT, approval, event, DOT, law, Nuxt, Directus, or Qdrant mutation occurred.

Remaining blocker

SB-1 APR action-type owner-line has not yet been rehearsed. It is the last owner-line prerequisite before a future build-intake can be considered for the owner/APR substrate.

Authorized next action

Authorize SB-1 APR action-type author-mode BEGIN..ROLLBACK rehearsal only:

• rehearse adding the four APR action-type rows;
• verify handler_ref remains fail-closed/unimplemented;
• avoid action='add' auto-approve bypass; use safe action semantics as designed;
• prove triggers/quorum behavior where possible;
• prove rollback and entry==exit.

No COMMIT, no approval creation, no persistent mutation, no Phase-B handler activation.
