 ## Choose build or launch
 
+For T3 Code Mobile, run `node scripts/mobile-native-client.ts ensure ios <simulator-udid>` from the checkout on the simulator host first. It checks the local Expo native fingerprint against the installed client and builds/installs when stale, missing, or unknown. Then launch with the intended Metro bundle. Authorized verification includes native builds and installs; do not stop because the existing client is old. Use `check` instead of `ensure` only when the user explicitly prohibits rebuilding or requests a read-only check.

 - Use `build_run_sim` when native source, native dependencies, entitlements, or project configuration changed.
 - Use `test_sim` for the smallest relevant native test target or test cases; do not run an entire workspace test matrix routinely.
 - Use `launch_app_sim` when a compatible app is already installed and no native rebuild is needed.

+- When the change is platform-specific, test that platform. When neither platform is viable, report the missing SDK or emulator prerequisite rather than claiming verification. A missing development client is a build step, not a blocker.
 
 Do not treat unavailable iOS tooling as a blocker when Android is a valid representative target.
 
-## Choose the lightest valid launch path
+## Ensure a compatible native client
 
-- For JavaScript, TypeScript, or asset-only changes, reuse a compatible installed development client and start Metro. Do not rebuild native code merely to load a new bundle.
-- For native source, native dependencies, entitlements, config plugins, or generated project changes, rebuild the affected platform.
-- Use `vp run ios:dev` or `vp run android:dev` only when an Expo clean prebuild is actually required; both commands regenerate the native project.
-- If the user requested no native rebuild and no compatible app is installed, reuse an existing compatible `.app` or `.apk` artifact when available. Otherwise report the missing dev client instead of silently rebuilding.
+Authorized mobile verification includes building and installing a development client. A missing, stale, or unknown native client is not a reason to skip verification or leave a PR in draft. Build and install it, then continue. Respect an explicit user instruction not to rebuild; otherwise do not ask for separate permission.
 
-The development identity on both platforms is:
+Run this from the checkout being tested, on the machine that hosts the selected simulator or emulator. Select and boot one explicit iOS UDID or Android emulator serial first:
 
-- App: `T3 Code Dev`
-- Bundle/package identifier: `com.t3tools.t3code.dev`
-- URL scheme: `t3code-dev`
+```bash
+node scripts/mobile-native-client.ts ensure ios <simulator-udid>
+node scripts/mobile-native-client.ts ensure android <emulator-serial>
+```
+
+`ensure` compares the checkout's local Expo development fingerprint and the installed app's binary contents against the last successful build record. It reuses a matching client; otherwise it runs a clean prebuild, builds and installs the development app, and records the successful result. It does not start Metro. Start Metro below after it succeeds. On hosts with an `agent-job` requirement, run the entire `ensure` command through that queue.
+
+For a read-only decision, use `check` in place of `ensure`. Exit 0 means compatible, 2 means build required, and 1 means an operational error. An app installed outside this helper is initially unknown and gets rebuilt once. Records are local to the simulator host under `~/.cache/t3code/native-clients` and work across checkouts. Do not copy records between machines or write them manually.
+
+A JavaScript-only diff, bundle identifier, app version, or recent install date does not prove native compatibility. Always check the whole checkout. Expo fingerprints are computed locally with `APP_VARIANT=development`; no EAS credentials or cloud build are required. Generated `ios/` and `android/` directories are excluded by `.fingerprintignore`, so edit native source modules or config plugins rather than generated output.
 
-Bundle or package presence proves the correct variant, not native compatibility. Reuse it only when the current changes did not alter its Expo SDK, native dependencies, config plugins, entitlements, generated project, or native source.
+The development identity is `T3 Code Dev`, bundle/package `com.t3tools.t3code.dev`, scheme `t3code-dev`. If a build fails, investigate the build error and fix the local prerequisites. Report the concrete failure if it cannot be resolved, not “no compatible client.”

+# Untrusted half of the macOS preview. This runs PR code (including fork PRs)
+# with a read-only token and no secrets, and only produces the JS bundle. The
+# trusted half, desktop-macos-preview-publish.yml, runs on workflow_run from
+# main, verifies the PR author is vouched, then packages, signs, notarizes, and
+# publishes the bundle without ever executing it.
+#
+# The label is a one-shot request for the commit it was applied to, not a
+# standing subscription: the trusted half removes it once this run completes,
+# and later pushes do not build until a maintainer applies it again. Each
+# signed preview is therefore an explicit per-commit decision.
+#
+# Closing the PR is handled by the publish workflow too, since deleting the
+# download needs a write token.

 - Upon request, user-visible frontend changes should get one integrated pass in a real client: `test-t3-app` for web, `test-t3-mobile` for mobile. The primary agent does this once after integrating.

 The app's minimum is Android 7.0 (API 24), declared in `app.config.ts` and enforced by the relay's device-registration schema. Compile/target SDK versions follow the locked Expo/React Native toolchain (currently API 36). Notification channels begin at API 26; the notification permission prompt begins at API 33. Live Update promotion requires API 36 and remains subject to system settings and device support. Alerts and ordinary activity cards work below API 36.
 
+On Android 16+, open T3 Code Settings → Live Update Settings to allow status bar chips. Android controls this separately from notification permission. The chip reads `Working` during work, `Approve` for approvals, and `Answer` for input requests; completed work returns to a normal notification. Use an Android 16 QPR2 or newer emulator image to verify the shipped promotion behavior.
+
 API 24–25 use a single inexact system alarm to expire cards after process exit, with no exact-alarm permission. Android can delay that alarm in power-saving modes. API 26+ use notification timeouts. Disabling activity, dismissal, account changes and sign-out cancel the legacy alarm. A stale expiry broadcast cannot remove a newer run's card.
 
 The native notification tests cover API 24, 26, 33 and 36 (plus API 25 for legacy expiry) using Robolectric. To compile the module, run these tests and run Android lint, use the following command from a generated `apps/mobile/android` project with JDK 21 available. No Firebase, signing or relay secrets are required:

+## Pull request macOS previews
+
+Labeling a PR `preview:mac` publishes a signed, notarized Apple Silicon DMG with T3 Connect enabled
+to the rolling `desktop-preview` prerelease, and works for fork PRs. The label is a one-shot request
+for the commit it is applied to: the trusted workflow removes it once the build is in hand, and later
+pushes do not build until a maintainer applies it again. Every signed preview is therefore a
+per-commit maintainer decision, which matters because the result carries the Developer ID signature.
+Vouching a contributor lets their labeled commits be signed; it is not a standing grant. The build is
+split so the Developer ID certificate never shares a job with PR code:
+
+- `.github/workflows/desktop-macos-preview.yml` runs on `pull_request` with no secrets and builds
+  only the JS bundle from the PR (the same `js-bundle` artifact `release.yml` produces).
+- `.github/workflows/desktop-macos-preview-publish.yml` runs on `workflow_run` from `main`. It
+  refuses unless the PR is open, still labeled, its head is the built commit, and the author is a
+  bot, a collaborator, or listed in `.github/VOUCHED.td` (read from the default branch, so a PR cannot vouch
+  for itself). It then packages and signs the bundle through `release-desktop.yml` checked out at
+  `main`, so packaging, native helpers, and the Electron/desktop dependencies come from `main`, not
+  the PR. Only the version and the public T3 Connect identifiers in `.env.example` are read from the
+  PR commit, as data, so the signed app's passkey entitlement matches the bundle. A PR that changes
+  packaging must use the `channel=preview` release train above instead.
+
+Before handing the bundle to the signing runner, the trusted workflow validates its ZIP entries
+and accepts only regular files under `server/dist` and `desktop/dist-electron`, plus the directory
+entries that lead to those roots. The artifact cannot
+overwrite packaging code or installed dependencies. The bundle is copied into the app, never executed,
+on the signing runner. The
+`pull_request_target` cleanup job in the publish workflow removes the download when the PR closes, or
+when the label is removed by hand before a build consumed it, and never checks out PR code.
