* feat(relay): drain pace window as a reviewed same-cap input, with drain-aware 503 gates The same-cap roll drained every cell over a fixed 300 s window, so a US roll re-placed hosts at ~2/s and spent ~10 minutes draining and waiting for quiet. The window is now a dispatch input from a closed set (300000, 60000, 30000), defaulting to today's 300000. - Below the default is refused for anything but US general cells; Asia drains are bound by their targets' accept rate, and migration-only cells hold no hosts. - A non-default window must be named in the confirmation, the canary authority records it (v2), and a batch may run at its canary's window or slower only. - Each cell job re-checks the window, scales the restart-safe timeout with it (15-min lease + window, unchanged at the default), and records what the cell applied and when it settled. - The report-only shadow gate takes the director's drain-return deferrals out of the 503 count (window and baselines), adds the rung's 5-min non-drain 503 budget and a Retry-After check, and reports the measured re-placement rate. - relay-workflows.md documents the pace ladder and what each rung records. * fix(relay): judge paced drains on counted 503s against the pre-drain minutes, and seal the canary's pace verdict Review of #25639 replayed the shadow gate: it read 10-01 c29 as unverified (the log read stopped at 20k entries), false-blocked 10-02 c22, and was blind on four cells whose 24 h/48 h baseline held an incident. - Director 503s now come from Cloud Run's request_count, aligned per minute by Cloud Monitoring, so volume cannot truncate the count. - The background is the median of the 10 same-day minutes before the drain; the 24 h/48 h baselines are gone. - Scheduled 503s come out: drain-return deferrals and sticky/placement answers to a host's own early retry (host-rate-limited, host-in-flight), each split across the minutes its 30 s sample covers. - The rung budget counts only sustained breaches: two straight minutes over max(1.5x, +20) warn, over max(2x, +40) would-block. - The report carries a paceVerdict over the three pace checks. seal_canary downloads the canary cell's report and seals that verdict; a batch below the default pace needs PASS, from a report on the same cell that drained at that pace. - Docs: the step-down rule reads paceVerdict, 30 s waits for the lane service time (#25645), and the staging step is dropped since staging drains unpaced. Replayed read-only: 10-01 c29 would-block (9 minutes over 41.5/min); all nine 10-02 cells and 10-01 c25 paceVerdict PASS. * fix(relay): a partial count already past a block line blocks, in the shadow gate's Cloud SQL and pool checks A truncated FATAL count is a floor, and one runtime sample over the SQL-failure line is a fact, so neither waits for a complete read. The waiter-run rule still needs a complete run, since holes can join two runs into one. * fix(relay): a canary pace PASS needs a real cohort and whole telemetry; one median-based 503 check From the final review of #25639: - canaryPaceVerdict seals PASS only from a report that drained at least 400 hosts (about half a 10-02 US cell), so a near-empty canary cannot authorize a fast batch. - A director-metrics sub-window with fewer samples than one instance emits is unverified, so an empty or short Logging answer is never a calm drain. - seal_canary names the shadow artifact, report path and cell from the gate's normalized cell list, as cell_1 uploads it. - director503 folds into nonDrain503Budget as a single-minute spike rule, max(10x median, 200), dropping the pre-drain peak statistic. All 30 replayed windows keep their verdicts.
