From fa06ebcba8a0e9807eec72d4d15e4ad60f865195 Mon Sep 17 00:00:00 2001 From: Edgar Arakelyan Date: Fri, 13 Nov 2026 10:42:39 -0800 Subject: [PATCH 1/4] fix(computers): three checks that failed on a busy runner give it room From the last day and a half of local-backends runs, main's included: - The probe's recording check required a 2 s recording's segments to span 1.6 s; a recorder that took a moment to start spanned 1.40 s and 1.59 s, failing gate 3, so whichever test composed that computer failed (computer_app_test, website_browser_test). It now requires half the recording, as it does of the frames, which a stream that stalls still fails. - desktop_example_test required the recording's first frame showing a clicked cell within one frame interval of the screenshot that first showed it; a frame written 37 ms late failed it. It allows two intervals. - page_driver_test checked that no session owner was left 0.1 s after a bounded call; it now waits up to 5 s for them to end, so one that never ends still fails it.

The driver does ask them at once (runtime.ready_checks gathers them). The clock now starts at the request, and each app's check takes 2 s, so asked at once the status takes about 2 s, one after another 6 s, and the bound is 4 s.

Both come down to when the recorder writes a frame under load. The test still checks each screenshot against the recording's nearest frame, in time and in pixels, which is what puts the two on one clock. The probe test failed on #666 with "scored below 1 (probe: 0)" and nothing more; it now names each probe check that failed and why, from the run's verification.
