Production code matches reviewed d7e381517352601b3185d74bd2ff43ca03c09406; final commit only compares the asserted stored state directly so TypeScript does not require null narrowing.

RED original production source3728adf, final regression cases: 3 expected failures. Raw16557-terminal-red2.log.
RED guard-only source60e9e3a: terminal-update publish failure leaves running row, 1 failed2 passed. Raw16557-terminal-red-guardonly.log.
GREEN final implementation before final test assertion adjustment: whole RunExecutionService.test.ts46 passed exit0. Raw16557-terminal-green2.log.

Earlier original-issue current-main red/green plus provider-core typecheck and all-five-file lint are recorded in16557-final-verification.txt. Recovery files and provider-core source unchanged since that verification. Independent fresh Sol/Opus reviews approve production revisiond7e3815. No new runtime capture or visual row: this is additional server lifecycle preservation proof, with no reachable rendered change.
