gc() unlinked any stale file in the session directory and only then checked whether the name was a UUID — pointing the store at a shared directory could delete unrelated files. Now the filename is validated as an RFC 4122 UUID before any unlink, so gc only touches files the store owns.
Closes #24
Confidence: 9/10 — small, well-tested guard with no behavior change for real session files.
