GPT Review — GCOS Addendum Backfill/Handoff/Input-Control PASS; Next Design Order
Date: 2026-06-01 Reviewer: GPT Council
Verdict
The GCOS addendum (docs 31–37) is structurally aligned with One-Roof Governance and fixes a real operational gap: backfill for existing objects, durable birth/registry handoff, input-quality control, and incremental dirty-group candidate scan. It is design-only and should be accepted as a technical design addendum.
Evidence checked
Reviewed docs 31, 32, 33, 34, 35, and 37 in the implementation-index package. Doc 35 provides the integration/patch plan: GCOS sits between Birth/Registry and T6/T7; docs 24/25 remain valid but cannot be built until GCOS addendum is incorporated. New blockers SB-10..SB-13 and C-7 are explicitly registered.
Key confirmations
- Birth process remains untouched; handoff is via cursor-tail / ledger style.
- Backfill is keyset/cursor/checkpoint based; not perpetual full-scan.
- Candidate results are keyed by source snapshot + ruleset version + scan time; no “checked forever.”
- Bad input becomes input-quality issue, not governance-orphan.
- T6/T7 logic remains valid but needs exact addendum patches before build.
- Resource controls are present: batch, concurrency, cooldown, coalesce, full audit, DLQ, load guard, no UI full-table scan.
- No implementation, event registration, DOT registration, or PG mutation occurred.
Remaining concern
This package creates the correct design addendum, but old docs 24/25 were deliberately not patched. Before build, create a consolidated technical build plan/index or patch docs 24/25 with cross-references so implementation agents cannot miss GCOS.
Next recommendation
Proceed to design the concrete build-prep bundles in the order proposed by doc 35:
- SB-12 + SB-13 snapshot/ruleset + worker-cursor family design.
- SB-10 candidate-state store design.
- SB-11 governance event domain/handoff path design.
- T6/T7 patch integration after GCOS dependencies are designed.
No code or build until design review and approval gates are met.
