Prunes tests that check styling, layout, exact wording or wall-clock time, and makes the editor tests independent of WebKit's animation frames. Every test that guards a person's text or data, the Marfa mapping, link resolution and the Live plan is unchanged.

What was removed or changed

Test	Reason
SoftSelectionTests (2 tests)	Checked the frames of a drawn selection mark. Pure layout.
WebViewContainerTests	Checked the web view's frame against layout constants.
LibraryPerformanceTests	Wall-clock ceilings (50 ms) that fail on a loaded machine and only report on a fixture library.
InterfaceStyleTests.semanticFontsScaleWithoutChangingTheirTraits	Restated how fonts scale. The test for unreadable stored sizes stays.
ItemTableLayoutTests.theRingFollowsTheTone	Restated a mapping from status to a drawn mark.
SidebarTests.theFootsDotIsOrange...	Restated a mapping from connection state to a dot color.
SyncStatusTests.countsAgreeWithTheirNouns	Restated string formatting that the other wording tests already exercise.
SyncWordingTests (exact paragraphs)	Exact-sentence assertions replaced with the facts that matter (kind, actions, counts, the way out named). Both no-jargon tests stay.
EditorTests.nativeFindGeometryFollowsViewportAndAppearanceChanges	Needed the page to draw frames, which a covered window never does (#144). Layout of Find marks only.
EditorTests+Header margin loop	Checked title and text margins at four widths after waiting for frames (#144). Layout only. The scroll and crossing checks stay.
changingItemsAfterScrollingStartsAtTheTopAndStaysThere	Kept, rewritten to wait on conditions instead of frames (#144).
MarfaSourceOfflineTests.aWriteIsQueuedAtOnceWhileTheServerHangs	Depended on a real address (10.255.255.1), which answers "connection refused" on some networks, so it failed every time here. Replaced by aWriteIsQueuedAtOnceWhileARefreshIsHeld, which holds a fake refresh in flight, submits a write, and checks it is shown and queued before the refresh is released. It uses no socket and no real address.
DownloadedFilesTests deadline loop	A hand-rolled 5 s loop replaced with eventuallyAsking.
editor every pin is one height...	Checked CSS custom properties and a pin count.
editor the header and the text share one column...	Matched regular expressions against style.css.
editor embed label tests	Two fixed 20 ms sleeps replaced with vi.waitFor.

Counts

	Before	After
Swift @Test declarations	870	861
Unit plan test cases passed	985 (1 failed)	978 (0 failed)
Editor tests (vitest)	68	66

The fixed sleeps left in the unit tests are "did not happen" checks with a comment saying so, as AGENTS.md allows.

Tested

• Unit plan through heavy-run: all 978 cases pass.
• Editor tests: 66 pass, run three times in a row.
• Not run: the UI plan (takes over the screen; the UI tests are unchanged) and the Live plan.

Issues

Closes #144.

Closes #64. It does not reproduce. Both tests (aCopyExpiredByAMoveKeepsEveryQueuedWriteAndTheView and aConflictedCopyIsShownBesideItsOriginal) passed 20 of 20 in isolation and in the full Unit plan, on the current Swift SDK (0.0.37). The issue was filed against 0.0.8, 29 releases ago, so the cause was fixed in the package, not in this repository. No test was changed for it.
