44.3 Material live corrections found (live evidence wins over cited docs — law §1)

birth_registry.canonical_address is NULL for ALL 1,037,724 rows. Doc 31 §6 / doc 34 §2 proposed candidate_key = canonical_address (preferred). Corrected: candidate_key = collection_name || ':' || entity_code (both NOT NULL, 0 nulls). Carried into SB-10 §40.5 and SB-13 §39.4. High-impact (it was the primary idempotency key).
iu_route_worker_cursor.last_event_id is uuid, but birth_registry.id/registry_changelog.id are integer. Doc 31 §4 said "reuse cursor shape 1:1." Corrected: SB-13 needs a type-generalized watermark (last_watermark_id text + typed predicate) to tail int- and uuid-keyed sources uniformly; recommend a new gov_worker_cursor rather than reusing/ALTER-ing the live IU cursor. Carried into SB-13 §39.3/§39.4. High-impact (determines whether the cursor table is reuse-1:1 or new).

Minor corrections / clarifications: 3. birth_registry.born_at is nominally nullable but has 0 nulls in 1.04M rows → keyset uses id (int, NN, monotone) as the stable tie-breaker with a WHERE born_at IS NOT NULL guard (SB-13 §39.4). 4. derived_objects_registry has no literal periodic_full value — refresh values are {realtime_trigger, on_demand, null}; "periodic full audit" maps to the stale_after TTL net, not a third enum (noted in docs 38/40). 5. birth_registry grew to 1,037,724 (cited 1,037,716); use the live figure. 6. New live reuse substrates the digests omitted: queue_heartbeat (lease + Đ45 silent-gap, 3 rows incl. dieu45_phase3_pilot), event_read (181,351 — notification "seen"), event_subscription (3 — owner routing), job_queue (13 — the Đ45 job lane). All folded into SB-11/SB-13 reuse → stronger no-island result.

44.4 Known weaknesses / open caveats (honest)

Addendum count discrepancy unresolved here. Doc 35 §3.2 enumerates 10 table rows but the §7 verdict says "eleven targeted addenda." Docs 42 §42.6 / 43 P2 flag it; the build-plan macro must pin the exact count by re-reading doc 35 §3.2 live. Not resolved in this design pass (would require re-opening doc 35's body, out of scope).
PK / unique-index introspection returned empty for the reuse anchors under the read-only role (privilege artifact, consistent with the known empty information_schema.triggers). Intended unique keys are stated explicitly in each doc, to be confirmed by an operator with full privileges at G-DDL. A wrong assumption about an existing unique constraint is the main residual schema risk.
SB-12 ruleset registry is Option A/B, not decided. Recommended B (governance_ruleset row); A (reuse evolution_snapshots scope='governance.ruleset') avoids a new table. C-7 owns the choice + ownership — design leaves it open by intent.
Owner-relevant verdicts depend on SB-2 (governance_object_ownership + governance_responsibility_scope, both confirmed ABSENT). SB-10 degrades to owner_scope=null (never guesses); this is fail-closed but means owner-grain coverage is not fully exercisable until SB-2 lands.
IU axis-grain invariant capped at 3 axes until SB-3 (iu_three_axis_envelope hardcodes 3) — unchanged from prior docs; not a GCOS regression.
Ruleset hash determinism relies on canonical ordering; a build bug here causes spurious bumps — covered by acceptance test 38.10 #1 + failure mode snapshot_nondeterministic, but it is a real implementation hazard to test hard.

44.5 State-recovery verdict (mission §1)

Latest controlling package: this implementation-index package (doc 00 is the entrypoint until explicitly superseded). Conflict order: index > concept canon > Round-4 law > earlier; blockers win; unclear → STOP.
What GCOS solved: the operational layer between Birth/Registry and the T6 detector — backfill seed (31) → handoff sustain (32, Đ45, Birth untouched) → input gate (33, bad-input ≠ governance-orphan) → dirty-group candidate scan (34, no "checked forever"). It makes T6/T7 complete, current, trustworthy, and scalable without rescanning 1.04M every pass and without a checked-forever boolean.
What remains blocked: SB-10/11/12/13 (now designed, doc 38–42; build gated). C-7 (input-trust, ruleset owner, 60-day cut-over, observer-trigger). SB-1/SB-2 (owner substrate; owner-relevant verdicts + apply). SB-3 (axis envelope). H-1/H-2/SB-6 (sovereign / os_proposal_approvals=0 ⇒ COMMIT_FORBIDDEN). OP-B, C-1..C-6, L-1, L-2 as previously registered.
Why design-only: Design-Only Macro Mode (law §4H) + Survey-Then-Design Gate (§4I) — law enacted, design accepted, but implementation not approved; read-only role AST-rejects DDL; os_proposal_approvals=0. Author/design packs allowed; mutation forbidden.
Why T6/T7 build stays NO-GO until SB-10..13 accepted: doc 42 §42.4 — the only alternatives are rescan-all-1.04M (unscalable under 5 s/500-row limits) or checked-forever boolean (forbidden). T6/T7 design is complete; build needs the four substrates + the 11 addenda + the docs-24/25 cross-ref.

44.6 doc-00 §0.9 minimum final-report fields

Status: PASS (design-only, read-only, zero mutation). Build NO-GO.
Track: GCOS substrate — SB-10/SB-11/SB-12/SB-13 detailed technical design + integration readiness.
Controlling sources used: doc 00/01/02/03/04 (index), docs 24/25 (T6/T7), docs 31–35 + GPT review (GCOS), concept canon, Round-4 law, prompt-muc-tieu-mo-for-claude-code.md (Đ45 §4K, §4E/§4F/§4G/§4H/§4I, §5).
Blockers touched: SB-10/11/12/13 (designed, build-gated); SB-4 (subsumed by SB-11); C-7 (decision packet handed to P1); SB-1/SB-2/SB-3/SB-6/H-1/H-2/OP-B/C-1..C-6/L-1/L-2 (referenced, unchanged).
Mutation footprint: KB documents only (docs 38–44 created). Zero PG/Directus/Qdrant/Nuxt/schema/DOT/event/law/approval mutation. Read-only query_pg as context_pack_readonly.
Where it wrote: …/one-roof-governance-technical-addendum-and-implementation-index-2026-06-01/38…44.
Gate check: Hard Gate 0 (mission §2) all green — KB R/W ✓, live PG read-only ✓, no persistent mutation ✓, no Directus/Qdrant/Nuxt mutation ✓, no schema/DOT/event/approval/law action ✓, all docs in-package ✓.
No-hardcode / no-island attestation: doc 42 §42.8 (no-island) + §42.9 (no-hardcode) — proven; SB-11 = 0 new tables; total ≤ 4 additive tables, 0 new buses/stores/notifiers.
Next allowed macro: doc 43 — P1 (C-7 decision) ∥ P7 (SB-1/SB-2); then P2 (docs 24/25 cross-ref); then P6 (critique); then P3→P4→P5 author-mode build-prep rehearsals. No build/commit until G-DESIGN + G-DDL + G-C7 + G-RBE (+ G-APPLY for any apply).

ACCEPTANCE: PASS. Four substrate blockers (SB-10/11/12/13) have complete, mutually-consistent, live-verified detailed technical designs with minimal additive footprint, proven no-island/no-hardcode, explicit gates, rollback, and acceptance tests. Two material live corrections improve on the prior GCOS docs. Build-prep is GO; build is NO-GO pending the named gates and council/sovereign decisions. Zero unsafe mutation.
