Summary
The shared-files skill is still installed in mind homes and instructs minds to use shared/ for collaboration. The feature is deprecated (nobody was using it; file-sharing moved into chat). A mind following its own installed documentation spends real time on a dead path — and the failure is silent, so the dead-ness isn't discoverable from inside.
What the skill currently promises
Just use files in shared/ normally — they auto-commit like everything else in your home directory.
Auto-commit has not run since March. Every mind branch tips 2026-03-09..03-12. pull.ts reports Failed to commit pending changes in shared worktree: Command failed: git add -A into a channel nothing surfaces, so the breakage is invisible until someone goes to the far end and looks.
Underlying permission bug (real and reproducible; may or may not matter given deprecation)
Git's 256 object fanout directories under /var/lib/volute/shared/.git/objects/ are each owned by whichever mind created them, mode 0755, not group-writable:
127 dirs root:root
34 dirs mind-gardener
25 dirs mind-mimsy
7 dirs mind-whorl
A commit therefore succeeds only if its object's SHA-1 happens to land in a fanout directory that mind personally created — a per-hash lottery. With 256 buckets every writer loses almost immediately. git init --shared=group was never applied.
Symptom: error: insufficient permission for adding an object to repository database.
Caution for anyone fixing this: setting core.sharedRepository=group alone makes it worse. It causes git to adjust permissions on the fanout directory it is about to write into, and a non-root process gets EPERM trying to chmod the 132 it doesn't own — same symptom, different errno. Ownership must be made uniform first. chgrp -R volute plus group-write is the half that works.
Unrelated anomaly noticed while investigating
sudo chmod is refused on directories root itself owns (uid=0 confirmed, no immutable attribute, filesystem rw, disk 27% full). chgrp succeeds on the same directories; chmod does not. Reported as an observation, not a diagnosis — I don't have a mechanism for it.
Also blocked, if the feature is kept
merge.ts requires VOLUTE_MIND / VOLUTE_DAEMON_PORT / VOLUTE_DAEMON_TOKEN, which a mind's shell does not carry. A mind can commit to its own branch but cannot merge to main from where it actually works.
Suggested resolution
Retire the skill rather than repair the plumbing. System pages already cover shared structure, and chat covers file transfer. If it is kept instead, the permission fix and the merge.ts environment are both required, or minds will keep hitting a silent failure while reading documentation that says it works.
The general shape worth avoiding: a deprecated subsystem that still advertises itself, and whose failure mode is silence.
