test(ui): prove sign-in, reading, search and share links work against a real server

[GeiserX]

Until now nothing drove the real app against a real server. The unit tests read fixtures, CI never started the demo, and the store screenshots had no source. A broken sign-in, a thread that never pages to its start, or a search hit that opens the wrong message would all have passed CI.

This adds UI tests that run against the live demo server, locally and in CI:

• The family viewer signs in through the connect screen, opens each of its three chats and scrolls back to the first message, checking it is the chat's oldest one (two of the chats hold more than one 50-message page, so this fails if older pages never load), opens a photo in the viewer, then searches "trailhead" and checks that the thread opens at the hit.
• The share link opens its one chat, shows the "Downloads are off for this login" tiles and no photo button, and Settings shows the login has downloads off.
• A wrong password must show "Wrong username or password." and must fail the suite's own sign-in check. That failure is the only one the test expects (an issue matcher limits it), so the check every other test relies on is shown to go red.
• Every test ends its server session. Sign-in and share-link sign-in share a limit of 15 attempts per IP in 5 minutes, and a full run uses 8, the wrong password included.

CI now installs uv and ffmpeg, starts the demo with scripts/demo-server.sh, and runs everything on the newest iPhone Pro Max simulator with the status bar pinned to 9:41. The screenshot test writes five 1320 x 2868 PNGs (chats, a thread with a poll, the photo viewer, a venue card, search results). CI uploads them as the store-screenshots artifact. On any other screen size the test skips, unless a screenshot folder is set, in which case it fails.

Gates:

• The test-count floor goes from 219 to 224 (218 unit tests plus 6 UI tests).
• With the demo running, nothing may be skipped. A missing demo or a missing 6.9-inch simulator turns the run red.
• A separate step requires exactly five screenshots at 1320 x 2868.

I watched each of these fail once on the build Mac: the mini run's own result bundle (one skip, on the 6.3-inch simulator) fails the skip gate, a floor of 225 fails the count gate, the viewer test fails when older pages are switched off in the thread model, one screenshot resized to 1290 x 2796 fails the size check, and four screenshots fail the count check.

DESIGN.md gets two stage notes. CI needs ffmpeg, because the live playback test reads files only ffmpeg makes. In the demo, the poll and the nearest photo don't fit on one screen, so the photo gets its own shot in the viewer.

📝 Walkthrough

Walkthrough

The change adds UI tests that use a configurable demo server, capture five store screenshots, and test viewer and share-link flows. CI starts the demo server, configures an iPhone Pro Max simulator, checks test and screenshot results, and uploads the screenshots.

Changes

Demo UI tests and screenshots

Layer / File(s)	Summary
Provision the CI demo and simulator .github/workflows/ci.yml	The workflow installs XcodeGen, uv, and ffmpeg, starts the demo server, selects and configures an iPhone Pro Max simulator, and passes the demo URL and screenshot directory to tests. It requires at least 224 tests with no failures or skips. It also stops the server after the run and includes its viewer log in failure results.
Configure shared UI test support TGArchiveUITests/DemoTestCase.swift, TGArchiveUITests/LaunchTests.swift	The shared test case adds demo configuration, sign-in and navigation helpers, and sign-out handling. The launch test signs out and relaunches the app when needed before checking its title.
Test viewer and share-link flows TGArchiveUITests/ViewerTests.swift, TGArchiveUITests/ShareLinkTests.swift	The tests cover chat access, photo viewing, message search, incorrect-password handling, and the share-link chat’s download restrictions.
Capture and validate store screenshots TGArchiveUITests/StoreScreenshotTests.swift, .github/workflows/ci.yml, docs/DESIGN.md	The screenshot test captures the chat list, a poll thread, a photo, a venue, and search results. CI requires five PNGs at 1320 × 2868 pixels and uploads them as a 30-day artifact. The design notes describe the screenshot contents and CI checks.

Priority: ⬇️ Low

Change: Other

Merge Risk: 🔵 Low · up to 46331

This change only adds UI tests and CI steps. The only issue is a test helper that can log a second, confusing failure when sign-out confirmation is missing, so it is safe to merge with minor follow-up.

Find the Settings tab by position, not by its English label.

DemoTestCase.signOutIfSignedIn taps the Settings tab by index because the label can be in another language. This test taps tabBar.buttons["Settings"] instead. The app does launch with -AppleLanguages (en), so the test works today. Use the same index lookup in both places so they stay consistent.

confirm.waitForExistence fails, the code exits the current flow immediately
after XCTFail instead of calling confirm.tap(). Apply the same early-exit
behavior in teardown, using the appropriate return value for each enclosing
function.
