projects/<key>/memory/ (Claude Code's auto memory) sits beside the session dirs, and `purge claude memory` removed it whole. Only an 8-4-4-4-12 hex id now reaches the session's directories, session files, jobs and tmp dirs. Any other id keeps the pre-#31 reach, the `<id>.jsonl` file alone (test_a4 still purges "uuid-c"); its residual is that file and nothing holds it in use. The shared _plausible_id is unchanged for the other adapters. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
