66 — GCOS Author-Mode Rehearsal Run Self-Review & Acceptance

Doc: 66. Role: Self-review of the rehearsal run (docs 57–65) against the mission acceptance criteria and the forbidden list. Status: PASS. All six rehearsals executed live as BEGIN..ROLLBACK; entry==exit proven; zero forbidden action. Date: 2026-06-01.

---

66.1 Acceptance criteria (mission §6)

#	Criterion	Result
1	State recovery complete	✅ ruling + law + docs 00/45/48/49/53/55 read; scope/authorized/forbidden/order/rollback-method stated (doc 57 §57.0)
2	Delegated ruling scope honored	✅ rehearsal-only; C-1/C-2/C-7 defaults exercised; no activation, no COMMIT
3	All rehearsals run or skipped with hard reason	✅ R-1..R-8 all run live (none skipped)
4	Every executed rehearsal ends in ROLLBACK	✅ docs 58–63 transcripts; even the F-R7-1 error aborted→auto-rollback (zero residue)
5	Entry==exit proven	✅ doc 64 — every object pre==post, same- and separate-session
6	No residue	✅ doc 64 — all governance-scoped counts 0; targets NULL
7	No COMMIT	✅ no COMMIT issued anywhere; os_proposal_approvals=0 throughout
8	No approval/event/DOT/production mutation	✅ approvals 211/42/6 unchanged; outbox governance=0; no DOT registered; no Directus/Qdrant/Nuxt touch
9	Readiness verdict clear	✅ doc 65 — G-DDL/G-RBE rehearsed GREEN; build NO-GO on M-1+C-7
10	Next prompt prepared	✅ doc 65 §65.3

Verdict: PASS.

66.2 Forbidden-compliance (mission §7 + ruling)

COMMIT — none. Persistent PG mutation — none (entry==exit, doc 64). Directus/Qdrant/Nuxt mutation — none (PG-only, read+rolled-back DDL). Schema/table/view/function/trigger left behind — none (all to_regclass NULL). DOT registration — none (rolled back). Event registration left behind — none. Event emit — none (event_outbox governance=0, unchanged). Approval creation / self-approval — none (os_proposal_approvals=0). Law enactment / version / status bump — none (normative_registry=47, law_catalog=5 unchanged). Production route/API/UI — none. Implementation disguised as rehearsal — no (every txn ends in ROLLBACK; nothing committed). Hidden local governance island — no (reused single bus/store/audit/heartbeat/cursor-family/candidate-store; 0 new buses). Hardcode — no (no literal class/axis/owner/scope arrays; values from registries; absence→finding not invention).

66.3 Channel honesty (muc-tieu-mo §3.5/§4E)

The execution channel was verified before deep work (doc 57 §57.1), not assumed: SSH→docker→psql proven, plus a DDL BEGIN..ROLLBACK probe on a throwaway object (zero residue). Classification = EXECUTION_MODE (rollback-only) — authority (ruling) + channel both pass, COMMIT out of scope. This is a genuine upgrade over the prior docs (19/48), which assumed OPERATOR_HANDOFF_MODE because they only had query_pg; this run found and used the real operator channel and executed the rehearsals the package had only prepared.

66.4 What went beyond a paper rehearsal (value added)

• Caught 5 real schema/constraint drifts (F-57-1/2/3/4, F-R7-1/2) the representative DDL's (...) placeholders hid — each would have failed a verbatim build. All mapped under §4G and fed back into doc 65 §65.2 for the build.
• Proved the text-generalized watermark live by storing int (1055575) and uuid (00004a74-…) in one column and running keyset on both source types.
• Proved the no-checked-forever invariant by grepping the live CREATE (0 forbidden booleans) and showing the decaying-triple verdict.
• Proved group-grain Δrows=0 with live child counts (registry_changelog 20,043 → 1 group row).
• Proved a live-enforced FK candidate→ruleset in the combined transaction.
• Proved even an erroring transaction leaves zero residue without COMMIT.

66.5 Weaknesses / open items

• W1 — DDL is representative, not final. Column lists were finalized against live schema where they touched it; full per-column finalization (indexes, defaults, additional constraints) still belongs to the build macro (doc 38–41 are the authority).
• W2 — Drift findings need design-doc fold-back. F-57-1..F-R7-2 are recorded in doc 65 but the frozen design docs 38/39/41 + addenda #4/#5 should be surgically patched at build time (not done here to avoid editing frozen docs mid-rehearsal).
• W3 — OI-45-1 (doc 35 §7 "eleven"→"ten") still open.
• W4 — Heavy-table reads bounded. birth_registry group-grain demo used an id<=50000 keyset slice to stay under the 5 s timeout; the full-audit cadence sizing remains a build-time concern (doc 35 §3.2 scale controls).
• W5 — C-7 unruled. The rehearsal exercised C-7 defaults only; activation paths (input.* trust, ruleset activation, observer-trigger) remain gated on the real council ruling.
• W6 — SB-2 tables (governance_object_ownership/_responsibility_scope) were confirmed absent but not rehearsed in this run (mission scope was SB-10/11/12/13 + combined + T6/T7); their author-mode rehearsal is doc 19's separate line.

66.6 Acceptance

ACCEPTED — PASS. The GCOS substrate rehearsal cycle ran live, ended in ROLLBACK every time, proved entry==exit with zero residue, and committed nothing. Build remains NO-GO (os_proposal_approvals=0 + C-7 pending + SB-1/SB-2 unbuilt). Next: doc 65 §65.3 P1 (C-7 council ruling) ∥ P2 (SB-1/SB-2 build line) → P3 GPT review → P4 gated build.
