* topology: keep the oversized verdict after the location list is gone The per-replica oversized marks live in the volume's location list, which is deleted when its last location leaves and recreated flagless on the next registration. Between that recreation and the next heartbeat that re-measures the volume, ensureCorrectWritables saw no mark and re-admitted an oversized volume to the writable list; two other paths (quarantine release, mark-writable) never consulted the marks at all. VolumeLayout now remembers the oversized verdict per vid, written only by heartbeat sizes and forgotten only when a report measures the volume under the limit. The writable admission gate itself refuses a marked volume, and the vacuum commit path drops a verdict its live size check has just disproved.

When the registering report knows the volume's size, refresh the oversized state before the writable check instead of waiting for the next heartbeat pass.

Keep one verdict per reporting replica: an under-limit report clears only its own, and a replica that never returns cannot pin its volume out of writables forever because the verdict ages out. The vacuum commit now feeds the node's fresh answer through the same per-replica bookkeeping instead of erasing the whole verdict.

Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * topology: cover per-replica oversized verdicts in tests One replica shrinking must not clear a still-oversized replica's remembered verdict; cover that plus a size-less re-registration before the second replica is re-measured. The vacuum-commit case now shrinks the stored record first, since the commit re-derives the mark from the node's own answer. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * topology: judge the vacuum commit by the size it just measured SetVolumeAvailable rebuilt the oversized verdict from the cached VolumeInfo, which still carries the pre-compaction size until the next heartbeat. A commit that shrank a volume under the limit re-marked the replica oversized and never restored writes. The commit path already asks every replica for its fresh size; pass it through per replica and record it on the mark, the verdict, and the size tracking seed. * topology: hold an expired oversized verdict while its replica is back The TTL forgives a replica that never returns, but a remount announces the volume without a size and registration skips the oversized check. Deleting the verdict on expiry then re-admitted a still-oversized volume until the next size-bearing heartbeat. Keep counting an expired verdict while its replica sits in the live location list, and keep sweeping verdicts whose replicas stayed gone. --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: chrislusf <chrislusf@gmail.com>
