Opus Confirmation — GPT Patches to B3-A2 — 2026-05-12

Source

User relayed Opus confirmation after reading patched files:

• knowledge/dev/laws/dieu44-trien-khai/design/p3d-birth-system-b3a2-blocker-resolution-design.md rev6
• knowledge/dev/laws/dieu44-trien-khai/reports/p3d-birth-system-b3a2-blocker-resolution-design-report.md rev3

Opus confirmation summary

Opus confirmed both GPT patches as correct:

1. coverage_scope_status='SYSTEM_MANAGED' is invalid under current CHECK constraint. Correct approach:

   • keep coverage_scope_status within allowed values: IN_SCOPE, USER_EXCLUDED, FUTURE_SCOPE, ORPHAN_REGISTRY;
   • for birth_registry, use coverage_scope_status='IN_SCOPE' plus coverage_exemption_reason='SYSTEM_MANAGED: self-referential birth system table — recursive trigger risk';
   • use coverage_status='BIRTH_EXEMPT_SYSTEM_LOG_OR_AUDIT'.

2. fn_birth_registry_auto_id whitelist is conditional. It becomes validator-green only after read-only equivalence probe using pg_get_functiondef(), sample birth rows, and GPT review. Until then the 3 variant-bound collections remain accepted-by-design-but-not-yet-validator-green.

Additional GPT cleanup after Opus confirmation

GPT made two minor clarification patches after reading Opus confirmation:

• B3-A2 report: clarified that B3-A3 trigger install prompt comes only after B3-A2a probe and B3-A2b exemption prompt/review pass.
• B3-A2 design: changed option-table wording to CONDITIONAL whitelist, preventing accidental immediate validator acceptance.
