When a thread runs many local servers, the Servers list in the thread details card grows very long and pushes everything else down.
Now it shows 4 servers, then a "Show N more" row that adds 4 more each time, then "Show less" to collapse back to 4. It uses the same chevron row as the PR list in this card. Extra server rows are left out of the card's density measurement, the same way expanded PR rows are. Without that, expanding could switch the card to compact mode and hide the list, including the "Show less" row.
| Before | After | Expanded |
|---|---|---|
| before.png | after-1.png | after-3.png |
Proof: new browser tests for paging (ThreadServersPanel.browser.test.tsx) and for the card staying full while expanded (ThreadDetailsCard.browser.test.tsx). Both fail on main and pass with this change. vp run check:changed passes. The screenshots come from the real component in the browser test runner, because T3's Browser panel cannot start Chrome as root on this host. Mobile has no Servers list, so it needs no change.

Taken over from @Bil0000 (land). No code changes; evidence and verification added below. The branch gained two merges of main: the first resolves a conflict with #28585, which added [data-thread-automations-panel] to the same density-exclusion selector in ThreadDetailsCard.tsx, by keeping both entries (and both tests). The second, 44a5e8f65c, touches no file in this PR; captures were taken at 7c0cf8340c.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — The server list now shows four servers initially, with controls to reveal more or collapse. Human confirmation is required for this changed default visibility, although server operations and permissions remain unchanged.

Wait for the row-count assertions.
Wrap the row-count assertions in vi.waitFor so they wait for DOM updates after each click.

Fixed in cea5473. Row counts now use vi.waitFor, and the 8-row state also checks the four overflow markers that ThreadDetailsCard measures.
@Bil0000 Thanks for the fix in cea5473. The reported vi.waitFor changes address this finding. The overflow-marker assertion also checks the markers used for density measurement.

Key the server list by thread so expansion does not carry over.
ThreadServersPanel keeps visibleCount in component state. Nothing resets it when threadId changes. Server-thread navigation reuses the same ChatView, ThreadDetailsPanel, and ThreadServersPanel instances. If one thread's list is expanded and the user opens another thread, the new thread starts with the expanded count instead of four. Its "Show less" control is also shown in the expanded state. A key on the ThreadServersPanel element in ThreadDetailsPanel resets this state on each thread change.

Valid. Fixed in cea5473. I put the key inside the panel instead of in ThreadDetailsPanel: ThreadServersPanel renders an inner list keyed by environmentId:threadId, so paging remounts per thread. The test now expands thread A, switches to B, then back to A, and expects 4 rows each time. It fails without the key (8 rows).
@Bil0000 The internal key works. In the supplied code, ThreadServersList owns visibleCount and remounts when either environmentId or threadId changes. This resets paging to four rows without a key in ThreadDetailsPanel.
The reported A → B → A regression test covers the original failure.
