cmux-next: motion follow-ups to #22795 (suggestion-lists-float opens its own entries; pane motion help) by teamleaderleo · Pull Request #23357 · manaflow-ai/cmux

teamleaderleo · 2026-10-21T11:45:04Z

Two follow-ups to #22795 (directional motion), now merged.

What changes

suggestion-lists-float opens only its own gallery entries. It opened /gallery/frame.html without entryPath, which loads every gallery entry, and waited in EVERY_ENTRY_PENDING (scripts/check-browser-test-lanes.ts) because cmux-next: right-side panels slide in without lag or overflow; directional enter and exit in the agent pane #22795 changed the file. It now builds its stage URLs with galleryFrame(entry, { variant }) and warms agent-pane.composer and agent-pane.new-tab with warmGalleryFrame, as the other narrowed tests do; its line leaves EVERY_ENTRY_PENDING.
The motion.pane.variant Debug help is current. It said content keeps its final size. Since cmux-next: right-side panels slide in without lag or overflow; directional enter and exit in the agent pane #22795 it keeps the larger of its starting and final size until the spring lands (motion.pane.holdContent).

Changelog

none

No capture: the only native change is a Debug tunable's help text in Settings; no layout or motion changes.

Observed / Not run

Observed: bun scripts/check-browser-test-lanes.ts passes ("Browser test lane imports checked."); scripts/web-lint.sh passes; prepush-gate.py reports no new violations.
Not run: the browser test itself (it runs only in CI or on a Freestyle VM); CI's webview shard runs it.

Summary by cubic

Fixes two follow-ups to the directional motion changes from #22795.

The suggestion-lists-float test now loads and warms only its own gallery entries (agent-pane.composer and agent-pane.new-tab) via galleryFrame and warmGalleryFrame, instead of loading /gallery/frame.html with every entry. Its lane no longer waits in EVERY_ENTRY_PENDING.
Updates the motion.pane.variant Debug help to reflect that content keeps the larger of its starting and final size until the spring lands, not just its final size.

^{Written for commit 5ad602b. Summary will update on new commits.}

…ts own gallery entries; the pane motion help names the content hold suggestion-lists-float opened /gallery/frame.html without entryPath and waited in EVERY_ENTRY_PENDING for #22795, which changed it; it now loads and warms only agent-pane.composer and agent-pane.new-tab. The motion.pane.variant help said content keeps its final size; since #22795 it keeps the larger of its starting and final size until the spring lands.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

CI fast guards failed on 5ad602b8b7 (https://github.com/manaflow-ai/cmux/actions/runs/39594289011). It does not block the merge; a red guard merged into main breaks it for every open PR.
The log named no failed step; see the run.

Agents: python3 scripts/ci/guard_attribution.py fix applies the mechanical fixes locally.
