| Total sessions on guest | 449 |
| Active/recent sessions (protected) | All 50 returned by session_info (most recent slice) |

The runbook's SELF-RECOVERY clause prescribes the exact response when the guest is already at ENOSPC before the task can preflight: no in-guest deletes, write a host SUMMARY, post a Notion MCQ recommending one restart, and rely on the daily cadence to self-maintain after the restart. That is what this run did. Zero files were touched on the guest. Every NEVER TOUCH protection held trivially because no candidate set was ever built.
The ENOSPC signature was confirmed twice:
ENOSPC: no space left on device, mkdir '/sessions/relaxed-festive-clarke/tmp/claude-1492'
session_info.list_sessions returned "50 of 449" — the 449 figure is the proximate cause. Closed-session working directories under /sessions/* have accumulated faster than the daily cleanup cycle has been removing them.
Restart the Cowork desktop app once. The restart clears closed-session ephemeral /sessions data and unblocks the guest immediately. The 3 AM ET cycle should self-stabilize after that. No host-side VHDX compaction is being requested in this run; the session backlog alone explains the fill.
COWORK-VM-CLEANUP-DEADLOCK-2026-06-07.md was written to the user-selected workspace folder (the mounted host path reachable from this run). It contains the same deadlock recap plus the table of skipped steps. Canonical host folder C:\Users\SAguiar\Documents\Codex\folder-cleanup-runs\ was not reachable because Desktop Commander was not loaded for this scheduled run; that is one of the items in the QA reflection below.C:\Users\SAguiar\Documents\Codex\folder-cleanup-runs\ path and not the user-selected workspace fallback. Reason: today's deadlock SUMMARY landed in the selected workspace folder because Desktop Commander was unavailable, which means future agents searching the canonical path will not find it.
