Failed to persist compaction: {persistence_error}; cleanup a

Error message

Failed to persist compaction: {persistence_error}; cleanup also failed: {cleanup_error}

What it means

Compound sentinel in trigger_compaction: the primary save_turn/save_thread persistence failed (persistence_error), and the follow-up cleanup_unaccepted_turn_records rollback also failed (cleanup_error). Both error strings are embedded; the store may retain a partially persisted compaction turn that the engine never acknowledged.

Solutions

1. Resolve the store-level persistence error (permissions, disk space, lock contention)
2. Manually inspect the thread's turn list for the orphaned compaction turn id and remove it
3. Ensure no concurrent compaction or shutdown is racing this trigger

When it happens
