TestFlight can't install TG Archive (Apple's missing beta contract on the app record), so we're publishing it on the App Store. App Review needs a way into the app. Running a public demo server for them means a host to keep up and a share link that expires every 14 days.

This adds a "Try the Demo" button on the connect screen. It opens the demo server's invented archive, which now ships inside the app: 15 chats, 398 messages and 27 photos, built from the committed fixtures by scripts/build-demo-archive.sh. DemoURLProtocol answers an ordinary APIClient for demo.tgarchive.invalid, a host that can never resolve. Every screen above it (chat list, threads, topics, search, the media viewer, settings) runs unchanged, and no archive request goes over the network (location cards still load Apple Maps tiles; videos and voice notes are not bundled and show as unavailable). The demo is never saved to the Keychain. A strip at the top of every screen says it is the demo, and "Exit Demo" (in the strip or in Settings) goes back to the connect screen. A relaunch also lands there.

Also in this PR:

  • The review notes template becomes the real notes, built around the demo: no sign-in, every endpoint the app calls, and why local-network http is allowed.
  • One line in each store description points to the demo.
  • The DESIGN cut-list entry against a demo button gets a note: it no longer needs a hostname.
  • Version 0.2.0, build 3, for the App Store upload.

Tests: 8 unit tests (routes, all three cursors, topics, search, photos and 404s, every bundled message decodes and every photo it shows is bundled, the session never touches the Keychain or the last server) and one UI test (open the demo, read a thread, open a photo, search, open a hit, exit, relaunch). CI's test-count floor goes from 228 to 237.

…ith no server

App Review, and anyone curious, can now open TG Archive without running a
Telegram-Archive server. "Try the Demo" on the connect screen opens the demo
server's invented archive, bundled in the app and answered by a URLProtocol
behind the ordinary APIClient, so no request leaves the phone. Every screen
says it is the demo, and Exit Demo returns to the connect screen.

📝 Walkthrough

The app now includes a synthetic archive that it serves locally, with a connect-screen entry point and demo-specific browsing and exit behavior. The changes also add archive-building instructions, tests, localized strings, App Store and review-note updates, and new version and CI test-count values.

Changes: Bundled demo experience

Layer / File(s) Summary
Build the bundled archive
scripts/build-demo-archive.sh, AGENTS.md
The script assembles archive data from fixtures and can convert referenced photos when a media directory is supplied. The build instructions describe the script and when to rerun it.
Serve archive API responses
TGArchive/Demo/DemoArchive.swift, TGArchiveTests/DemoArchiveTests.swift, docs/DESIGN.md
DemoArchive serves chat lists, message pages, search results, and bundled photos through DemoURLProtocol. Tests cover response data, cursors, topics, media, and demo-host routing.
Connect, browse, and exit demo
TGArchive/Session/SessionStore.swift, TGArchive/Features/Connect/ConnectView.swift, TGArchive/App/MainTabView.swift, TGArchive/Features/Settings/SettingsView.swift, TGArchive/Resources/*/Localizable.strings, TGArchiveTests/*, TGArchiveUITests/DemoModeTests.swift, TGArchiveTests/StoreTextTests.swift, docs/DESIGN.md, docs/app-store/*, docs/app-store/review-notes-template.md, .github/workflows/ci.yml, project.yml
The connect screen starts a non-persistent demo session. The app displays demo status and provides an exit action. Tests and documentation describe the flow; the CI test minimum and project version values are updated.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to a4bfd

The demo is usable, but its review notes should not promise that the app makes no network requests while demo content can invoke system map or media services. Correct the disclosure before submission.

- Line 15: Update the external-services disclosure in the review-notes template,
connect.demo.footer, and the DESIGN note to state that demo mode has no archive
server but MapKit may contact Apple and AVFoundation may attempt to load
unavailable video or audio; clarify that the archive and photos are bundled.
Keep the non-demo server disclosure and note that MapKit may also contact Apple
for location cards outside demo mode.
