The flaky test "a person sees their own with its status; the admin sees all and bans" in test/tui-notes.test.ts should now pass regardless of machine load. I only ran that file, and it passed (4/4, 8 s). The gate and tsc printed nothing, which I took as clean. I haven't seen the forge's check on this push.

Cause. The test's palette() helper typed each key and then waited only for the terminal to go quiet. The palette runs a local search after about 120 ms and a live re-run after about 400 ms, which redraws the list. On a loaded check machine, Enter could land in the gap between them. It then opened a row the redraw moved, so the test saw the wrong screen. The earlier fix (#8138) only raised the timeouts to 30 s, which did nothing for this.

Change. palette() now waits with settlePalette after each key. That is the existing helper from test/helpers/tui.ts, and test/egress-admin.test.ts already uses it the same way. It waits until app.paletteSettled is true and then settles the app. This is a test-only change: one import and one call in test/tui-notes.test.ts.

Left out. I did not touch the other TUI tests that press Enter after a palette query without settlePalette. I didn't audit them, so some may share the same weakness.

To try it. Run bun test test/tui-notes.test.ts.

Closes #8170
