The F6 once-gate was non-atomic: `settled.has` was read BEFORE the awaited terminal UPDATE and `settled.add` only after, so two concurrent finalizeRun calls for the same run (the documented safety-net catch vs a streamText terminal callback) both passed the check and both wrote the terminal row — double-write + last-write-wins status clobber, a window the bounded retry only widened. Restore a SYNCHRONOUS atomic claim before any await: capture the entry, then `active.delete` as a check-and-clear in one tick. The first caller claims and proceeds; a concurrent second caller finds the entry gone and returns at the claim, before any UPDATE. On a successful write we arm `settled` (post-write idempotency gate) and do not restore; on total bounded-retry failure we restore the claimed entry so a retrier can complete it — never both write and restore. Also fix the F6(b) JSDoc/comment to not overclaim an in-process retrier on the no-streamText path: there the only settler is the safety-net, so recovery on total UPDATE failure is the unconditional boot sweep on the next restart. Adds a concurrency test firing two simultaneous finalizeRun on one run (update held on a pending promise) asserting update is called EXACTLY ONCE; existing F6 retry-rides-transient + retain-on-total-failure tests stay green.
