Verified against the actual PR base rather than the local worktree (which has diverged on this file). The removed fields (jobRepository, the @Qualifier("jdbcTransactionManager") jdbcTransactionManager) have no usage anywhere in the class body, and the class itself has zero references anywhere in the repo outside its own declaration, so the constructor-arity change from @RequiredArgsConstructor is safe. No reflection/classgraph/MapStruct surface touches injected field names, so nothing else could break either.

One red CI shard (MySQL Shard 1) looks like unrelated infrastructure flake (actuator health check timeout), not something this change could cause.

Small note for a follow-up, not this PR: the exact same dead pair (jobRepository + jdbcTransactionManager) also exists in the sibling LoanCOBWorkerConfiguration.java, which was clearly the copy-paste source. Worth a separate cleanup PR.

Recommendation: APPROVE
