GPT Review — After Registries-Pivot Master Design Closeout

Date: 2026-05-31 Reviewer: GPT Council

Current status

The interrupted Registries-Pivot Master Design v0.1 package has been successfully closed out.

Canonical docs exist under: knowledge/dev/design/registries-pivot-os-agency/

Report summary exists: knowledge/dev/reports/architecture/registries-pivot-master-design-v0-1-readiness-gate-2026-05-31.md

Meaning

We now have an official design package, but it is not yet implementation-ready. The readiness verdict is: DESIGN COMPLETE / NOT YET IMPLEMENTABLE.

The main blocker is not missing design. It is the required ratification and count-integrity evidence gate.

What is done

• Master Design v0.1 completed.
• Law/principle map completed.
• Live substrate map completed.
• Data contract completed.
• Dynamic drilldown model completed.
• Pivot-only counting and invariant completed.
• Orphan/phantom policy completed with phantom still LAW_DEFINITION_GAP.
• Label/grouping policy completed.
• Pin/ghim policy completed.
• Notification/cleanup trigger contract completed.
• UI contract completed.
• No-hardcode acceptance tests completed.
• Implementation readiness gate completed.
• Next macro prompts completed.

Next step

Before implementation, run: REGISTRIES_PIVOT_COUNT_INTEGRITY_READONLY_REHEARSAL

Purpose:

• read-only/BEGIN..ROLLBACK validation of v_count_integrity over the correct leaf set;
• prove the count-integrity failure numbers;
• classify all drift rows;
• confirm missing pivots;
• decide what can move to PG view/function rehearsal.

Guardrails

• No production Nuxt.
• No schema commit.
• No route implementation.
• No fake approval.
• No hardcode.
• No frontend count logic.
• Every displayed count remains pivot-backed or PIVOT_MISSING.
