Expire only a still-open (INGEDIEND/IN_BEHANDELING) registration; an already resolved one (expired, or withdrawn/decided while it waited) is left untouched so the job completes without violating the aggregate invariant (§8.6). Closes the S-10a/S-11 race where a withdrawal-while-waiting would loop the expiry job. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
