Scope

Advances #435 as the durable generation/configuration-registry slice, stacked directly on #434 exact 68bdf2d984ca7686219c335a85a6574195675cbe. Current exact head remains 30d89fa8f4ba95d7ddb84dde8e3b7e5faebf0343, open · Draft · mergeable=true, 31 commits / 14 changed files. This PR owns immutable generation/configuration authority only.

The implementation persists canonical generation / owner-release / route / route-method records and reconstructs fresh #434 values while recomputing the canonical configuration digest. Generation IDs are non-reassignable; exact re-registration is idempotent only on a complete durable match. #434 optional-route admission remains durable without laundering absence into availability. Public generation DB capability identity remains construction-bound with weak lifetime evidence.

Current dependent stack

Draft #437 is exact 8a67b5cef24332619b3a4466e3787a851c299215, 258 ahead / 0 behind this parent with this parent as merge base. It owns 0019→0025 activation/recovery and serving-currentness behavior, not generation truth.

Its latest database repair closes a mismatch with application evidence semantics: bundle validity may not outlive an owner-operation observation. PostgreSQL RED 0e4d0b2... proves activation and recovery hostile cases; repair 2311c0d... requires evidence_valid_until_unix_ms <= observation.valid_until_unix_ms in both final 0025 validators and restores activation-side observed_at <= wall_clock parity. Source contract 127388c... pins those validators; 8a67b5c... preserves executable mode for the new PostgreSQL root. Lineage remains 0018→0025.

Draft #438 is ordinary-forward on that exact #437 and now d642eb71c05ae3990349a26facf30593a5703914, 7 ahead / 0 behind with #437 exact as merge base. It owns request selection only and adds no migration bytes. Its latest RED ef991ff... proves unknown declared paths and undeclared methods must be rejected before crossing PostgreSQL currentness; repair d642eb71... preselects the declared Path Item/method and pins the route ID before calling #437 availability/currentness. This does not move generation truth out of #436.

Architecture and verification boundary

#433 remains source exact 6fc85e4d8bb273adb0d5866d87554067c749179d, ADR 0432 Proposed/Draft. It must ordinary-forward adopt final admissible implementation evidence before Accepted/Ready; PR metadata is not source currentization.

Canonical package/PostgreSQL acceptance must use one unchanged exact #438 candidate tree. #260 package handoff includes request-routing currentness, preselection-before-DB regression, inherited #437 tests and 100% owned statement/branch/docstring/edge coverage. #311 PostgreSQL handoff includes complete 0018→0025 roots plus the evidence-lifetime regression. No predecessor GREEN transfers.

Production runtime/migrator DB-role separation and supported restore/failover provenance remain separate deployment acceptance. Migration 0026 remains owned by active Employment-absence work and must not be stolen.

Keep Draft. No force-push, destructive rebase, self-approval, gate weakening, mutable sibling source copy, cross-service SQL, synthetic status, predecessor-GREEN transfer, blind/no-op rerun, migration-number theft, premature Ready/merge, or simple Close is authorized.

Focused scope: exact 30d89fa8f4ba95d7ddb84dde8e3b7e5faebf0343, especially RED d9a96b8... and the route-partition change in GenerationRecordSet.from_admitted(). Please verify that canonical required-route admission may persist the complete declared generation when only required=False routes are unavailable, without allowing a required route to appear unavailable or conflating durable configuration with positive activation evidence.

@seonghobae Reviewed exact commit 30d89fa8f4ba95d7ddb84dde8e3b7e5faebf0343. I found no blocking issue in the requested scope.

GenerationRecordSet.from_admitted() first forces canonical receipt and source-generation revalidation through receipt.required_routes_admitted. Canonical admission fails closed when a required route has a missing or mismatched owner release.

The route-set check now requires the combined admitted_route_ids and unavailable_optional_route_ids to match every declared generation route. The additional required-route check rejects any required route in the unavailable set.

The durable record set is built from generation.routes, not from admitted routes. It therefore persists the complete declared configuration, including an unavailable required=False route. The RED test at test_generation_optional_route_persistence.py verifies this case and verifies reconstruction to the original generation.

The durable rows do not store observed-owner availability, receipt status, activation state, or authorization state. The implementation therefore does not convert optional-route persistence into positive activation evidence.

I did not execute repository tests because this review environment prohibits executing repository code.

ORDER BY 순서가 DB collation에 따라 달라집니다. 그래서 정확한 재등록이 거부될 수 있습니다.

  • register는 Line 206에서 existing != records로 tuple 순서까지 비교합니다.
  • recordsfrom_admitted에서 Python codepoint 순서로 정렬됩니다.
  • _load_record_setORDER BY service_id, ORDER BY route_id, ORDER BY route_id, method를 사용합니다. 이 정렬은 DB 기본 collation을 따릅니다.
  • DB collation이 en_US.UTF-8처럼 C가 아니면 _의 정렬 가중치가 다릅니다. route_idjob_viewjobs_list를 예로 듭니다. Python에서는 job_view가 먼저 옵니다. en_US collation에서는 jobs_list가 먼저 옵니다.
  • 이 경우 같은 자료를 다시 등록해도 "generation_id is already bound to different durable material" 오류가 발생합니다.
  • load는 영향이 없습니다. restore_generation이 Python에서 다시 정렬합니다.

모든 정렬에 COLLATE "C"를 지정하십시오. 다른 방법도 있습니다. _load_record_set에서 tuple을 Python sorted()로 정규화할 수 있습니다.

🐛 수정안
 FROM public.product_composition_owner_release
 WHERE generation_id = %s
-ORDER BY service_id
+ORDER BY service_id COLLATE "C"
 FROM public.product_composition_route
 WHERE generation_id = %s
-ORDER BY route_id
+ORDER BY route_id COLLATE "C"
 FROM public.product_composition_route_method
 WHERE generation_id = %s
-ORDER BY route_id, method
+ORDER BY route_id COLLATE "C", method COLLATE "C"

ID 두 개가 _로 인해 정렬 순서가 달라지는 경우를 회귀 테스트로 추가하십시오. test_postgres_generation_registry.py의 스크립트 테스트는 이미 정렬된 행을 주입합니다. 그래서 이 결함을 잡지 못합니다.

migration 텍스트 테스트 두 개가 한정되지 않은 이름을 찾습니다. 그래서 두 테스트가 실패합니다.

migration은 모든 테이블과 트리거 대상에 public.을 붙입니다. 두 테스트는 아직 public.이 없는 문자열을 찾습니다. "... ON product_composition_generation""... ON public.product_composition_generation"의 부분 문자열이 아닙니다. 그래서 assert가 실패합니다.
