When compaction fails, the \"Error during compaction:\" message is now built from a fixed prefix followed by the error detail. The wording you see is likely the same as before.\n\n**Why**\n\nA fixed prefix means compaction errors may now be recognised in other places by that prefix.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
