Anthropic is removing the 5-hour limit in stages (from 2026-10-31), and
an account without it reports the weekly window alone. Until now the pool
took such an account for an unprobed seat: always eligible, ranked after
every other, never held to the weekly cutoff, with no cap on its passes.
- The burst window is the 5-hour one, else the weekly one
(Seats::BurstWindow). An account whose burst window is the weekly one is
ranked by it and admitted under the 95 % cutoff with the passes in
flight projected on it, at the measured share per pass (0.04 at xhigh,
0.125 otherwise; REVIEW_GATES_LENS_COST_7D_PCT), and waits for the weekly
reset when over it.
- Every OAuth account and the local login takes at most 128 passes at once,
every driver's counted (REVIEW_GATES_OAUTH_CONCURRENCY): every run
measured with 149 or more in flight on one account drew usage-limit
rejections, none of the 119 with 139 or fewer.
- A 'concurrents' rejection pauses the seat for 20 s or its retry-after,
not until a window's reset (a seat sat two hours at 10 % on one).
- Board entries, the folded foreign record and the board's view carry
cost7d, so the drivers see each other's weekly load.
- `seats` and the log table say `no limit` in such an account's 5-hour
column; the board's others-line names its weekly projection.
