Atomically delete all Lives in this workspace
Delete all Lives owned by the authenticated personal workspace in one account-locked transaction. Current live.delete authority is rechecked after lock acquisition; foreign account IDs return 404. Returns 200 with the actual deleted count, including zero. No per-Live If-Match is used. Concurrent creation serializes on the same account lock; session shutdown follows committed deletion. Idempotency-Key is unsupported. Inspect the collection after an ambiguous response instead of blindly retrying, since a later retry could delete newly created Lives.
Required scopes: live.delete. Scopes intersect current authority; browser cookies never authenticate REST.
Authentication
Personal bearer credential issued through existing account settings or browser-approved CLI flow. Must be active, finite, unexpired, unrevoked, within any rotation overlap, and bound to an active personal membership/user/account. Explicit scopes intersect current user permissions; empty existing personal scopes inherit current user authority. Not an OAuth grant or service token. Browser cookies are ignored.
