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.

The seats of .env and the ledger, the probe, placement, settling a
finished pass, the child's credentials, the OpenRouter seats, and the
board every driver on the machine shares, in one shape and under one
lock. A driver is alive while its lifetime lock is held; with no lock file
natively its pid and start time decide, and in the sandbox it is taken for
alive.
:Http is the HTTP the driver needs, on FetchHTTP1: a status outside 2xx is
HttpError, every other failure carries a fixed text. :Platform gains
MakeDirs, with the last directory's own mode, and errno texts for its
writes and locks.
The tests cover the seat pool and several drivers at once, less the checks
that drive the pool's Scheduler, Admission and Stacks.
