65 — Rehearsal Readiness Verdict & Next Prompts

Doc: 65. Role: Readiness verdict after the GCOS author-mode rehearsal run (docs 57–64) and the paste-ready next prompts. Authority: doc 42 §42.5 gate table; doc 49 gate checklist; doc 53 orchestration; the GPT delegated ruling. Status: REHEARSAL GREEN (G-DDL + G-RBE for the substrate). BUILD = NO-GO. Master gate os_proposal_approvals=0 ⇒ COMMIT_FORBIDDEN; C-7 pending; SB-1/SB-2 not built. Date: 2026-06-01.

65.1 Readiness verdict

The GCOS substrate is rehearsal-proven additive, reversible, no-island, no-hardcode, register-before-emit, and zero-emit — under live execution. Every rehearsal (R-2..R-7) ran as BEGIN..ROLLBACK on the live directus DB via the operator channel and proved entry==exit (doc 64). This converts the previously-untested G-DDL and G-RBE gates from "not rehearsed" to rehearsed-GREEN.

Gate (doc 42 §42.5)	Before this run	After this run
G-DESIGN (docs 38–41 accepted)	MET	MET
G-DDL (operator reversible BEGIN/ROLLBACK, 0 collisions, tables confirmed absent)	NOT rehearsed	MET (rehearsed GREEN, docs 58–62)
G-RBE (register-before-emit discipline; rows active=false; zero emit)	NOT rehearsed	MET as rehearsal (docs 61–62); active=true flip still deferred to T7 build
G-C7 (council ruling A-3..A-7)	PENDING	PENDING (ruling authorizes rehearsal, not activation)
G-SB2 / G-SB1A (owner table / Phase-A action-types)	design only	design only (SB-1/SB-2 not built)
G-APPLY (os_proposal_approvals>0 + sovereign)	NOT-MET	NOT-MET (still 0)
M-1 master gate os_proposal_approvals>0	NOT-MET (0)	NOT-MET (0) ⇒ COMMIT_FORBIDDEN

Build = NO-GO. What is now ready is the DDL/registration itself (proven reversible & live-compatible). What is not ready: a recorded human sovereign approval (M-1), the C-7 council rulings (A-3..A-7), and SB-1/SB-2 build for owner-relevant work and the apply DOT.

65.2 Drift findings to fold into the build (discovered live)

These must be applied before any COMMIT build (all are §4G surgical drift, contract unchanged):

• F-57-1 queue_heartbeat: use executor_name/executor_kind (PK executor_name); executor_kind∈{…,PG_worker,…}; metadata Điều-45 safe-check (no body/content/secret keys). SB-13 build DDL/inserts must use these names.
• F-57-2/3/4 event_type_registry: delivery_lane='delayed' (not deferred); event_stream∈{alert(findings),health(heartbeats)} (not governance); default_severity medium→warning. SB-11 registration must use these enum values; event_domain='governance' is the new free-text domain.
• F-R7-1 dot_coverage_required.domain FK → dot_domains(code): build addendum #5 must register governance.{backfill,handoff,input,candidate} in dot_domains first.
• F-R7-2 dot_tools Birth-Gate code-format PREFIX-NNN warning on dot_governance_* (non-blocking): decide rename to GOVDOT-### vs accept warning — addendum #4.
• OI-45-1 doc 35 §7 "eleven" → "ten" reconciliation (count pinned at 10).

65.3 Next macro (the gated-build line is still NO-GO)

Recommended order (doc 53 §53.8 / doc 50 / doc 55):

1. P1 — C-7 council ruling session (doc 46 motions A-3..A-7): input-trust, ruleset owner, backfill-ruleset, 60-day cut-over, observer-trigger. Decision-intake only; no self-approval; silence ≠ approval (doc 52). Unblocks G-C7.
2. P2 — SB-1/SB-2 build line (after C-1/C-2 ruling, doc 23): owner table + 6-row scope + v_object_effective_owner; Phase-A action-types (handler_ref='unimplemented'). Owner-relevant T6 routing + the apply DOT depend on it.
3. P3 — Post-rehearsal GPT review of docs 57–66 (this run): confirm the drift findings and the rehearsal evidence are sufficient to author the build macro.
4. P4 — Gated build macro only after M-1 (os_proposal_approvals>0 with named sovereign sign-off) + every doc-49 MUST item green for the step: build SB-12→SB-13→SB-10 (COMMIT), register SB-11 active=false (COMMIT), then the 10 addenda for T6/T7. Each step re-runs the doc-45 §45.3 live block and the doc-48 pre-flight first.
5. P5 — Activation (Phase 2): Branch B handoff intake (Option A cursor-tail) → Branch A backfill seed (under C-7.3 ruleset) → Branch C/D input-gate + candidate scan → T7 active=true flip after full taxonomy.

Each next prompt starts from: muc-tieu-mo law → doc 00 → doc 45 → doc 42 → docs 38–41 → doc 46 → doc 49 → docs 57–64 (this run) → doc 66. No step may be flipped to GO by self-approval.

65.4 One-line state for the next agent

GCOS substrate (SB-10/11/12/13) is design-complete + rehearsal-GREEN (live BEGIN..ROLLBACK, entry==exit, docs 57–64); build remains NO-GO on os_proposal_approvals=0 + C-7 pending + SB-1/SB-2 unbuilt; fold drift findings F-57-1/2/3/4 + F-R7-1/2 into the build DDL.
