Replaces the C1 quarantine with real verification. Trusted results (lab token,
verified, or admin worker) are accepted directly as before. An untrusted
worker's result is recorded as one vote per (task, owner) in a new task_results
table; the task only completes once QUORUM_SIZE distinct owners submit the same
result hash, otherwise it returns to the queue for another independent compute.
- migration 0013 task_results (one vote per owner, quorum by result_sha256)
- CompleteTask branches on worker trust; unknown worker defaults trusted (safe:
completing needs the lease, whose owner is always a known registered worker)
- claim drops the quarantine and excludes chunks the owner already voted on
- domain Task.ReleaseAfterVote; QUORUM_SIZE config (default 2)
- unit tests: trusted direct-complete, untrusted needs-quorum, can-claim
Reducer and job done/total logic untouched — still one completed task per chunk.
