81 — SB-2 Owner-Line Rehearsal Self-Review

Doc: 81. Role: Self-review of the SB-2 owner-line author-mode rehearsal bundle (docs 75–80) against the mission acceptance criteria (§6) and forbidden list (§7). Date: 2026-06-01.

---

81.1 Acceptance criteria (mission §6) — 12/12

#	Criterion	Verdict	Evidence
1	State recovery complete	✅	doc 75 §75.0 — read muc-tieu-mo + docs 00/17/18/19/23/68/70 + both GPT rulings; SB-2 target/authorized/forbidden/rollback-method stated
2	Delegated authorization scope honored	✅	C-1 = SB-2 rehearsal-only; treated as NOT-sovereign, NOT-an-approval-record, NOT-COMMIT-permission (docs 75, 80)
3	Responsibility scope rehearsed	✅	doc 76 (R2 PASS)
4	Object ownership rehearsed	✅	doc 77 (R3 PASS)
5	Resolution/gap detection rehearsed	✅	doc 78 (R4 PASS)
6	Every executed rehearsal ends in ROLLBACK	✅	R2/R3/R4 each one BEGIN..ROLLBACK; post-rollback present=false (docs 76–78)
7	Entry == exit proven	✅	doc 79 — all pre==post across two channels
8	No residue remains	✅	doc 79 §79.1/79.2 — 4 targets NULL; all sentinel counts equal; idle_in_tx=0; sessions=0
9	No COMMIT occurred	✅	every transaction ROLLBACK; greenfield restored
10	No approval/event/DOT/production mutation	✅	approval_requests 211, apr_approvals 42, apr_action_types 6, os_proposal_approvals 0, event gov-domain 0, outbox gov 0, dot_tools 309, normative_registry 47 — all unchanged (doc 79)
11	Readiness verdict clear	✅	doc 80 — rehearsed-GREEN, build NO-GO, W6 closed
12	Next prompt prepared	✅	doc 80 §80.3 — P1 SB-1 rehearsal ∥ P2 GPT review → P3 C-1/C-2 intake → P4 gated build

81.2 Forbidden compliance (mission §7) — all clear

COMMIT ✗none · persistent PG mutation ✗none (greenfield restored) · Directus/Qdrant/Nuxt mutation ✗none (never touched) · schema/table/view/function/trigger left behind ✗none (post-rollback all NULL) · DOT registration ✗none (dot_tools 309 unchanged) · event registration left behind ✗none (event_type_registry 40, gov-domain 0) · event emit ✗none (outbox gov 0) · approval creation ✗none (approval_requests/apr_approvals/os_proposal_approvals all unchanged) · self-approval ✗none · law enactment ✗none (normative_registry 47) · version/status bump ✗none · production route/API/UI ✗none · implementation-disguised-as-rehearsal ✗none (only fresh trigger-less tables created and rolled back; no live object altered) · hidden local governance island ✗none (doc 78 D8: resolution reads only the single canonical store + scope ref + containment source) · hardcode ✗none (doc 76: scope is data; object_type resolves to meta_catalog; owner FK to governance_registry; inheritance computed).

81.3 Honesty / limitations

• SB-2 only. SB-1 (APR action-types) was not rehearsed this macro (only authorized via C-2 for rehearsal; ran SB-2 per the GPT review's specific authorization). The owner/apply line still needs SB-1 rehearsed — flagged as next P1 (doc 80).
• Fixture honesty. The R4 inheritance/gap proofs used a small _sb2_tree containment fixture standing in for production meta_catalog/registry parent linkage (rolled back). The resolution pattern is proven against a live engine; the production containment source wiring (which registry columns feed the walk) is a build-time detail, not yet wired. Stated plainly in doc 78 §78.1.
• Double-owner detector was demonstrated against an index-less probe table (legacy doubles), since the live partial unique index correctly prevents new doubles at write time (doc 78 D6). Both angles shown.
• No drift in SB-2 (contrast: GCOS rehearsals found 5). SB-2's contract used real codes/standard types, so no representative-DDL placeholder bit. If a build proceeds, re-verify governance_registry codes live again (live wins).
• Build remains NO-GO; nothing here moves M-1 or constitutes approval.

81.4 Self-review verdict

PASS — 12/12 acceptance, full forbidden compliance. SB-2 owner-line rehearsal is complete, reversible, and zero-residue; build NO-GO preserved.
