-# Native test merge gate
-
-`Native test suites` runs on pull requests, dev/main pushes and manual dispatch.
-`Authoritative native suites` fails unless both the native Node and complete
-Chromium jobs succeed; it has no continue-on-error, retries or path bypass.
-Repository administrators must require this check alongside the four pytest
-checks in branch protection. The audited public dev branch had no protection or
-ruleset, so merely adding workflow jobs cannot prevent a manual merge.
-
-`tests/native-ci-manifest.json` exhaustively partitions all native Node files:
-16 run in the native job,14 through existing pytest wrappers, one through the
-existing frontend architecture CI step, and the formerly live email-reply file
-through an explicitly identified Playwright driver. The manifest validator fails
-for omitted/duplicate/unreachable entries. Node emits individual JUnit identities
-and propagates its failure exit. No native file is newly run in each pytest shard.
-
-The browser job uses the existing one-worker Chromium config and all original129
-cases, plus one driver for the native email-reply contract. Its ephemeral account,
-SQLite DB and server are created by the config/setup; reuseExistingServer remains
-false. NPX startup is offline/cache-only in a private cache; Notes/editor behavior
-and Python MCP services remain real. No developer app or external account is used.
-
-Default CI trace suppression remains intact. Only this job's explicit opt-in plus
-a newly generated authenticated synthetic fixture marker permits failure traces.
-The existing structured sanitizer runs before artifacts are uploaded; invalid
-ownership, failed sanitization and missing tooling purge sensitive artifacts.
-Never upload the fixture directory, database or browser storage state.
-
-The stroke budget now excludes measured synthetic event-delivery pacing and also
-bounds actual Chromium main-thread work at the original5s. All240 samples and
-pixel/thumbnail/undo/redo assertions remain. Per-case timing attachments expose
-both clocks rather than treating driver frame cadence as application work.
-
-Three Bombadil properties remain opt-in: they require a Bombadil/browser scenario
-and bounded fuzz campaign; no authoritative execution is claimed. The two model
-smoke scripts require supplied model endpoints/models and remain explicit live
-operations. No credentials or live-service authorization are implied by CI setup.
-Firefox/WebKit alternatives remain opt-in and are not certified by Chromium CI.

+## Photo Editor Release Gate

 The photo editor release gate launches an isolated Odysseus server on port
 `7013` with a temporary SQLite database and disposable authenticated account.
 
@@ -18,3 +20,53 @@ The disposable account is created in the temporary data directory and exercises
 owner-scoped draft and notification routes without using an existing account.
 `PHOTO_EDITOR_E2E_AUTH=0` selects the legacy unauthenticated configuration for

+
+## Mobile and iOS Layout Suite
+
+The dedicated mobile and iOS layout suite exercises viewport behavior,
+accessibility zoom, scrolling, mobile safe-area geometry (Notes and Documents
+panes), and floating window restoration against an isolated local Odysseus server
+running on port `17739`.
+
+```bash
+npm install
+npm run test:ios-layout:chromium
+```
+
+### Profiles and Browser Prerequisites
+
+- **Chromium profiles** (`desktop-chromium`, `phone-chromium-portrait`, `phone-chromium-landscape`, `tablet-chromium`):
+  Provide automated baseline coverage in CI and local development without requiring
+  WebKit dependencies.
+- **WebKit profiles** (`phone-webkit-portrait`, `phone-webkit-landscape`, `tablet-webkit`):
+  Used for platform-oriented WebKit rendering validation. WebKit requires browser binaries:
+
+```bash
+npm run test:ios-layout:install
+# or: npx playwright install webkit
+npm run test:ios-layout:webkit
+```
+
+To run all installed profiles:
+
+```bash
+npm run test:ios-layout
+```
+
+### Evidence and Cleanup
+
+- **Evidence artifacts**: Screenshots are written to `test-results/ios-layout/` by
+  default and traces are written to `test-results/ios-layout-traces/`. Both paths
+  are git-ignored. Set `ODYSSEUS_LAYOUT_EVIDENCE_DIR` to override the screenshot
+  output path.
+- **Teardown**: Disposable application state and database files created in the
+  OS temporary directory are automatically cleaned up on both normal and failure
+  teardown, preserving diagnostic screenshots and failure traces.
+
+### Platform Considerations
+
+Emulated Chromium and WebKit viewports validate deterministic CSS cascade,
+computed layout geometry, viewport meta tags, and JavaScript restoration. However,
+browser emulation is not a physical device substitute: physical iOS Safari and
+standalone installed PWAs should still be verified separately for native gesture
+pinch-zoom, software keyboard dismissal transitions, and dynamic hardware notch/island insets.
