Brings in migrations 0023/0024. Batch-txn interaction reviewed: the batch holds 0023 push-gate shared locks (per community, insert-time) and 0024 channel-TTL shared locks (per channel, deferred at COMMIT) for all events in the lane until batch commit. Shared-shared admits concurrent lanes and direct inserts; no path takes two exclusive advisory locks, so no deadlock ordering is introduced by multi-key batches. Savepoint rollback of a poisoned event does not release its already-acquired shared push-gate lock (held to txn end) - correctness-neutral, slightly extends the window an exclusive lease activation may wait.
