test(webviews): mark the two 3 s frame-watch windows as fixed waits (base red) by teamleaderleo · Pull Request #23414 · manaflow-ai/cmux

teamleaderleo · 2026-10-21T12:53:45Z

feat-cmux-next is over the fixed-wait baseline. #23374 merged after the ratchet (#23365) had run its CI, and it added a 3 s waitForTimeout to agent-pane-stream-jitter.test.ts and to agent-pane-history-paging.test.ts. Every PR's webviews check now fails on check:fixed-waits.

Both waits are observation windows. Each test records every painted frame for 3 s after the chat opens, then asserts that nothing jumped. The fixed time is what the test measures, so each wait gets a // fixed-wait: marker and the baseline stays where it is.

Verified with bun run check:fixed-waits (992 on the baseline) and scripts/web-lint.sh. The change is comments only.

Summary by cubic

Marks the two 3-second frame-watch windows in the webviews tests as fixed waits so check:fixed-waits passes again on the baseline.

#23374 added the waits after the fixed-wait ratchet (#23365) had run CI, putting feat-cmux-next over its baseline. Both waits are observation windows: each test records painted frames for 3 s after the chat opens and asserts no jumps, so the fixed time is what the test measures. The change adds // fixed-wait: markers to both waits and is comments only.

^{Written for commit 93771bc. Summary will update on new commits.}

#23374 merged after the fixed-wait ratchet (#23365) ran CI, and it added a 3 s waitForTimeout in two tests, which puts feat-cmux-next over its baseline. Both waits are observation windows: the test records every painted frame for 3 s after the chat opens and asserts none jumped, so the time is the test. They carry a fixed-wait marker instead of a raised baseline.

cmux-next guards / defaults-snapshot is red on 18 of 21 fresh feat-cmux-next PR heads in the last 2:00:00, so it is most likely a base red, not this PR's. The base-reds lane has it; a base merge picks up the fix once it lands.

Review (subagent): SHIP at 93771bc

Reds are not this PR's (it only adds two // fixed-wait: comments in two test files):

react-apps-check (4) / shard check: TIMEOUT test/composer-type-scale.test.ts (known flaky timeout, also on other PRs).
defaults-snapshot: check-menu-actions flags FileExplorerSectionView.swift, a file this PR doesn't touch (base).
fast-gates post: GitHub installation API rate limit when posting the status; the gates themselves were success.

…#23450) * webviews: composer-type-scale reads its variants four pages at a time The file checks 41 gallery states one after another. Each one opens a fresh page that loads ~700 dev-server modules (~2.2 s), after a ~30 s cold warm-up, so the file ran 122-173 s alone on Huge Blue and 134 s next to five other browser test files: past the runner's 120 s file limit (react-apps-check timed it out on #23414). Four pages now read variants at once, each variant still in its own page, and each test awaits its own result. 73-84 s alone and under the same load, 41 pass.
