1558 -> 1430줄. 손수 abort 리스너가 0이 되어 래칫을 23에서 22로 조인다.
보존한 동작 셋:
- blockedTimeoutMs를 넘기지 않는다. blocked 이벤트는 유지보수에게 종단이다
— 배치는 opt-in 백그라운드 패스라 다른 컨텍스트가 사라지길 기대하며
데드라인만큼 매다는 비용이 BLOCKED를 보고하고 재시도시키는 것보다 크다
- upgrade 콜백을 생략한다. 커널은 생략을 "어떤 upgrade든 예상 밖"으로 읽고
거절하는데, 그게 유지보수가 늘 해온 동작이다. 빈 APPLIED를 넣으면 잘못된
스키마로 열린다
- onversionchange는 admit 안, 바인딩 검증 앞에 등록한다
계획이 blocked 회귀 테스트로 지목한 indexeddb-maintenance.test.ts:289-290은
실제로는 onblocked 경로가 아니라 drain 검사였다. MT의 진짜 blocked 경로에는
테스트가 없었으므로 새로 썼다.

STO-06: the IndexedDB codec migration commit chain runs entirely inside
IndexedDB callbacks, so up to maxRows records could keep executing past the
caller's cooperative deadline. The monotonic budget is now re-checked before
each record's first write; a started record still completes atomically, the
checkpoint advances only to the last safe key, and a clock failure aborts the
transaction rather than committing an unbounded batch.
STO-07: every OPFS worker request and response now carries
OPFS_WORKER_PROTOCOL_VERSION = 2, responses echo their request kind, and the
client validates the envelope and failure shape strictly while remembering the
expected kind per pending request. A page/worker release mismatch or a reply for
a different operation closes as UNSUPPORTED instead of being decoded as a value
of the wrong shape. UNSUPPORTED is used deliberately: the closed browser-data
taxonomy has no INCOMPATIBLE code and none was invented.
SW-10 and the OPFS/Web Push V2 wire rollouts remain deferred: they are
expand/dual-read/drain/contract deployments across releases rather than a single
in-repo change. The ledger records them as DEFERRED_TO_MIGRATION.
