 ## iPhone Duo testing
 
 Read [docs/iphone-duo-testing.md](docs/iphone-duo-testing.md) before Duo layout, pose, or recording work. Native `agent-device@0.21.20` hinge control is verified for open, book, and closed; use the scoped Duo toolchain and confirm angle plus app-visible geometry. A manual tabletop quarter-turn is verified; automated physical rotation remains unverified. Capture the lit panel explicitly and distinguish live continuity from saved-state reopening. Use `uv run` for Python helpers. Keep `CLAUDE.md` as the compatibility symlink to this file.
 
-Keep the catalog's OP card grid in both compact navigation and board/thread workspaces. Compact phones, the closed Duo, and an active native Duo division use two columns. With the Duo flat or on iPad, derive additional columns from the catalog pane's available width; a narrow iPad sidebar may still fit only two. Check the real two-to-more-to-two transition without relaunching or losing the selected thread and visible reply.

+- The build/test step has a 35-minute limit within the 40-minute job. A cold hosted build plus the full UI suite exceeded the earlier 25-minute limit while tests were still passing; keep time for compilation and slower simulator interaction. Gallery paging returns to the post associated with the selected media; test that post after dismissing the gallery instead of expecting the first post to remain onscreen. Favorites export checks must identify the actual `Browse View (Picker)` plus either `DOCPicker.filenameTextField` or Save. Verify the expected backup filename whenever its field is exposed. Captured hosted runs show that Browse can expose the filename without Save, while a folder can expose Save without the filename field.

 ## App behavior and validation
 
-Regular-width windows at least 580 pt wide use a board and thread workspace. Compact windows retain pushed thread navigation. Keep catalog selection visible, the selected thread readable, and the catalog title inline in the workspace. The sidebar uses the same OP card grid as compact navigation; the detail shows the selected thread and its media/actions. Compact phones and active Duo divisions keep two catalog columns. Flat Duo and regular iPad layouts add columns when the actual catalog pane has room, with approximately 140 pt per card; a narrow iPad sidebar still uses two. Selected cards have an accent outline. On a native horizontal Duo division, the catalog sits above the thread, with the system division and both 20 pt margins kept clear. iPad uses the balanced NavigationSplitView. Thread scrolling tracks post identity with scrollPosition(id:anchor:), so a window resize can keep the reading post visible. Build 1.3 (4) is the app version.
+Build 1.3 (5) uses the full available catalog width on iPad, with approximately 140 pt per OP card and at least two columns. Tapping a card pushes a full-screen thread. Back returns to the existing catalog and scroll position. This same navigation applies to compact phones and Duo, including Tabletop. Compact phones, the closed Duo, and active Duo divisions keep two catalog columns. The catalog is not a persistent sidebar or upper pane. Thread scrolling tracks post identity with `scrollPosition(id:anchor:)`, so resizing and activation can retain the reading post.
 
-Use debug-only in-memory catalog/thread/media fixtures. Check switching threads, returning to boards, gallery next-image/filmstrip/dismissal, favorites, settings, following a general, and post actions. The normal regression suite passes 95 unit tests and 20 UI tests on iPhone Air 26.5; pose-only cases skip there. After adding the post-ID scroll binding, 95 unit tests and eight focused quote, jump, resume, unread, recent-thread, and linked-post UI regressions pass on the final source. Mini portrait and Pro landscape walkthroughs both pass on that source.
+Use debug-only in-memory catalog/thread/media fixtures. `testCatalogOpensThreadsFullScreenAndReturnsToGrid` scrolls to the last invented card, opens its thread, checks that the thread fills the window, and returns to the same visible card. The opt-in walkthrough also checks returning to boards, gallery next-image/filmstrip/dismissal, favorites, settings, following a general, and post actions. The new twelve-card fixture is `--ui-catalog-grid-fixture`. Do not enable Duo pose-test flags on ordinary CI phones.
 
-Those counts describe build 3. Build 4 adds `testCompactCatalogKeepsTwoColumnsAndOpensThreads`, which checks real card frames and pushed navigation, and the opt-in `testDuoCatalogGridExpandsAndRefoldsWithoutLosingThread`. The native grid transition passes with two columns at 130 degrees, four at 180 degrees, and two after returning to 130 degrees, while thread 200 and reply 205 remain visible. Use `--ui-catalog-grid-fixture` for twelve invented catalog cards. Do not enable pose-test flags on ordinary CI phones.

 `orientation portrait` and `orientation landscape-right` returned success here, but the live native probe still reported the same 951 x 669 pt viewport and active vertical division. Therefore automated tabletop rotation is **unverified**. Do not label a book capture as tabletop, or treat an orientation command's success message as proof. A tabletop check must observe an active horizontal division in the app and inspect the actual rendered controls. Use the simulator's physical rotation control when available, and retain this manual requirement until app-visible geometry confirms a working automation path.
 
-The user's physical quarter-turn was verified on 2026-10-04: the native viewport became 669 x 951 pt, with an active horizontal division at y=455.5, height=40, width=669 pt, and 20 pt top/bottom margins. This proves the manual tabletop geometry; it does not prove an automated rotation command. Capture harnesses must preserve that orientation instead of setting landscape again during setup. Native arrangement views can then place primary and secondary content above and below the fold.

 ## App-specific checks
 
-Use the workspace. Verify the board catalog beside the selected thread, a visible scrolled reply, and background/foreground restoration. Background snapshot geometry must not push a standalone thread route. Once the device exposes a division (including inactive regions), retain the native ArrangementView container across folding and background snapshots. Keep the remembered workspace mode while inactive. Use a post-ID scroll position binding so pane resizing keeps the reading post visible rather than preserving a stale pixel offset. Keep navigation outside the arrangement.
+Use the workspace. Build 1.3 (5) uses a full-screen catalog and ordinary pushed thread navigation on every device. Tapping a card replaces the catalog with the thread; Back returns to the same scrolled catalog. Tabletop must not retain a catalog above a half-height thread, and iPad must not retain a catalog sidebar. Keep the post-ID scroll position binding for reading restoration. Navigation no longer depends on workspace mode or transient background geometry.
 
-The live native Tabletop-to-flat check passes with thread 200 and reply 205 visible before and after background reactivation. All four app process IDs remain unchanged; the other assertions cover Bible chapters 3/4, Mango reading page 2, and advancing real Earmark playback. The Tabletop tour also passes catalog/thread switching, all primary routes, and media actions.
+The closed outer display and an active native division keep two catalog columns. Flat Duo derives more columns from the full catalog width. For an active vertical division, use its native frame and margins to keep the two card columns clear of the hinge. The twelve-card fixture (`--ui-catalog-grid-fixture`) is debug-only.
 
-Build 1.3 (4) preserves the OP card catalog grid in the workspace. The closed outer display and an active native division keep two columns. Flat Duo uses the actual catalog pane width to add columns. `testDuoCatalogGridExpandsAndRefoldsWithoutLosingThread` passes a foreground 130-to-180-to-130-degree transition: two columns, four columns, then two, with thread 200 and reply 205 still visible. Run it with `TEST_RUNNER_CATALOG_GRID_CAPTURE=1`, preserve the verified manual tabletop quarter-turn, and use native hinge watchers at `CATALOG_GRID_READY_TO_UNFOLD` and `CATALOG_GRID_READY_TO_FOLD`. The twelve-card fixture is debug-only. The follow-up videos and native PNGs live in `../iphone-duo-review/2026-10-04-grid/`; earlier build 3 clips retain their original provenance.
+`testCatalogOpensThreadsFullScreenAndReturnsToGrid` checks a scrolled catalog, full-screen thread geometry, and Back restoring the same visible card. `testDuoCatalogGridExpandsAndRefoldsThenOpensThreadFullScreen` additionally checks a live 130-to-180-to-130-degree transition, opening and returning from threads, and reply 205 surviving background activation. Run it with `TEST_RUNNER_CATALOG_GRID_CAPTURE=1`, preserve the verified manual tabletop quarter-turn, and use native hinge watchers at `CATALOG_GRID_READY_TO_UNFOLD` and `CATALOG_GRID_READY_TO_FOLD`. Other opt-in cases cover full-screen Tabletop, background activation, and a vertical catalog hinge gutter. Do not enable native pose flags on ordinary CI phones.

+Historical build 3 and build 4 catalog/thread workspace checks remain in `../iphone-duo-review/2026-10-04-current/` and `../iphone-duo-review/2026-10-04-grid/`. They show the previous design.
