test(voice): prove ADR 0252 A→B→A history on live PostgreSQL - #763
Conversation
Add synthetic PostgreSQL integration tests for imported primary Voice intervals at before/between/after cutoffs, concurrent voc_type_code updates, GiST non-overlap, additional-assignment close, and 0237→0243 trigger replay. Bump to 2.22.1. Do not close #748 until protected delivery.
📝 WalkthroughWalkthroughADR 0252 Voice primary history에 대한 PostgreSQL 실통합 테스트를 추가했습니다. 테스트는 cutoff 조회, A→B→A 복원, 동시 업데이트, primary 비중첩, 추가 assignment 종료, 마이그레이션 재생을 검증합니다. 버전을 2.22.1로 갱신하고 관련 문서를 수정했습니다. ChangesVoice primary history 검증
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds live PostgreSQL coverage without changing production behavior. A test fixture uses a migration replay range that differs from deployment, so the tests may not fully validate the production migration path; the change is otherwise mergeable with explicit owner awareness or follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

📝 Info: Concurrent test serializes via the source_post row lock
The two workers serialize because each update source_post holds a row lock until commit; the second transaction re-reads the committed voc_type_code under READ COMMITTED and its trigger closes the prior interval before opening the new one. The GiST exclusion never fires, so errors == [] and the three non-overlapping rows hold as asserted.

📝 Info: Replay test mutates shared module database
test_combination_replay_is_replaced_by_history_migration replays 0237 then 0243 against the module-scoped database shared by every test in the file. It restores the correct trigger at the end and runs last by definition order, so default runs are safe. Under reordering (e.g. pytest-randomly) or a mid-test failure, the shared database is left with the ON CONFLICT trigger body, breaking the other tests.

📝 Info: First primary interval width relies on clock advancing
The first interval spans the post insert to the first update with no pg_sleep between them (the sleep sits between updates 1 and 2). first_from < first_to relies on wall-clock advancing across the two transactions. Equal timestamps would violate the effective_from < effective_to check constraint and fail the update. Negligible in practice, but a theoretical flakiness source.

_apply_migrations의 재생 범위를 migrate.sh와 일치시키십시오. migrate.sh는 0001~0011을 건너뛰고 0012부터 적용하지만, _apply_migrations는 migrations/*.sql 전체를 적용합니다. 따라서 이 테스트는 배포 재생 경로를 그대로 검증하지 않습니다.
