GPT Direction — Add Backfill, Handoff Queue, and Input Control to Governance Design

Date: 2026-06-01 Reviewer: GPT Council

Decision

The One-Roof Governance technical design must be extended before implementation. The current scanner/DOT/event design is not sufficient unless it explicitly covers two operational gaps:

1. Existing objects already born before governance coverage existed must be backfilled without omission and without repeated full rescans.
2. Future handoff from Birth/Registry into Governance Candidate/Coverage processing must be durable, replayable, and auditable.

Required additions

Add technical design branches for:

• Legacy/backfill governance onboarding for existing born/registered objects.
• Durable birth-to-governance handoff queue or ledger.
• Governance input quality gate.
• Incremental candidate scan using dirty group/source invalidation.
• Source snapshot and ruleset version tracking.
• Rescan/replay/backfill semantics.
• Proof of no missed objects and no duplicate processing.
• Failure recovery, idempotency, retry, DLQ, and audit.
• Compatibility with Điều 37, Điều 0-G Birth, Điều 2 Registry, Điều 36 Collection, Điều 45 Event/Queue, and Điều 31 System Integrity.

Principles

• Do not modify the existing Birth gate unless proven necessary.
• Birth remains responsible for existence/ID/registry visibility.
• Governance processing begins after birth/registry visibility.
• Do not store “object checked forever.” Store processing state by object/group + source snapshot + ruleset version.
• For large existing datasets, use backfill cursor/checkpoint and idempotent processing.
• For future events, use durable queue/ledger, not memory or prompt discipline.
• Governance scanner must only process inputs that pass minimum input-quality gates; bad inputs become input-quality/system issues, not silent classifications.

Placement

This addendum should be incorporated into the active implementation package:

Future agents must read this direction before continuing scanner/DOT implementation design.
