webviews/test/browser/grid-lines.test.ts:146 fails on base (runs 41568146239 at 7d8ae70, 41568701123 at 68fbf49) in all four session-info/grid-expanded scenes. Two merged PRs changed Session Info on purpose, and the scene still measured the old layout:

• Session Info: the page draws it by default again, with the native panel's header buttons (held for Leo) #32817 (Session Info header buttons) moved the fold chevron "one grid gap after the title" and made it visibility: hidden at rest (cmux#32765). The scene's section headings: trail cx line still looked for it on the trailing column, so it reported missing visible selector .acpmux-session-info-section__fold as a coverage failure. That line is removed. SessionInfo.gallery.tsx (chevronOnHoverAfterTitle, from Session Info: the page draws it by default again, with the native panel's header buttons (held for Leo) #32817) already checks where the chevron sits and that it shows on hover.
• Session Info: the machine, Context, what it runs, then Sources by default #32850 changed the default order to environment, context, usage, subagents, tasks, sources, changes, outputs, connectors (Leo: "1. Machines showing up so I know if it's cloud or not 2. context 3. Subagents/background tasks running 4. Sources"). usage to connectors (inner gap: got 1236, expected 12), about to made and made to running (block gaps: got 548 and -1188, expected 24) measured pairs that are no longer next to each other. The inner-gap pairs are now the about block's adjacent ones (environment to context, context to usage). The block-gap pairs are the runs the new order draws: about to running, running to made, and made to about (Connectors).

Only the test changes, no product code. Both PRs changed the behaviour on purpose.

Summary by cubic

Updates the grid-lines test scene so Session Info measurements match the behavior from #32817 and #32850, fixing a failure in all four session-info/grid-expanded scenes on base.

• Removes the fold chevron trail line; Session Info: the page draws it by default again, with the native panel's header buttons (held for Leo) #32817 moved the chevron after the title and hides it at rest, so it no longer sits on the trailing column.
• Swaps the inner-gap pairs to the adjacent sections in the new default order (environment to context, context to usage).
• Swaps the block-gap pairs to the runs the new order draws: about to running, running to made, and made to about.

Only the test changes; no product code.

Review (subagent opus-5.5 medium): SHIP at f1ead67
Visual verdict: unchanged by this diff (test-only)

Checked that #32817 (the fold chevron after the title, hidden at rest) and #32850 (the new DEFAULT_ORDER) changed these things on purpose. Checked that the new block pairs pick the first and last slot of each run (usage→subagents, tasks→sources, outputs→connectors) under gridLines.ts select's first-match rule. Checked that the remaining inner pairs are still adjacent. The diff changes only the test and hides no product regression.

Follow-ups:

• [follow-up] With the fold's trail line gone, nothing measures the exact one-grid-gap distance from the title to the chevron. chevronOnHoverAfterTitle only checks that the chevron comes after the title.
