-### #302 — `/compact` has no dry-run or preview mode before irreversible compaction
+### #305 — `/compact` has no dry-run or preview mode before irreversible compaction
 
 **Exact pinpoint:** When a user runs `/compact`, the operation executes immediately with no preview of: (1) which messages/turns will be removed, (2) how much context will be freed, (3) what summary will replace the removed turns, (4) estimated new token count post-compaction. Compaction is effectively irreversible within a session — there is no `/compact --dry-run` or `/compact --preview` that shows the plan before committing. Users discover the compaction result only after it has already modified session state.
