+## Drive agent turns for free
+
+Do not spend a paid model to see a turn render. `vp run dev` registers the
+`Replay (dev)` provider, which replays recorded turns with simulated streaming
+through the real adapter and orchestration. Its models are scenarios:
+`showcase` covers thinking, a plan, tool calls, an approval, and markdown.
+Press `Ctrl+Alt+Shift+R` for a picker (GNOME takes that key for screen
+recording), call `window.t3dev.replay("showcase")`
+with `preview_evaluate`, or run
+`node apps/server/src/bin.ts thread start --base-dir .t3 --provider devReplay --model showcase <project> "go"`.
+When the test needs real provider behavior, use that provider's cheapest
+model, such as Haiku for Claude or Luna for Codex.

 From the checkout being tested on the selected device host, run:
 
 ```bash
-node scripts/mobile-native-client.ts ensure <ios|android> <device-id>

 ```
 
-This reuses a matching native client or builds and installs one. Authorized
-mobile verification includes that build step unless the user prohibits it.
+This installs the dev client for the checkout's native fingerprint: from the
+device, the local cache, or the shared cache in seconds, building once only
+when no machine has that fingerprint yet (5-15 minutes, logged to the file it
+names). The device id may be omitted when exactly one device is booted. It
+prints one JSON line; on failure it names the next command. Authorized mobile
+verification includes that step unless the user prohibits it.
+
+For a device you opened in an agent-device session elsewhere (a device pool,
+cloud, or remote host), run `vp run mobile:install <ios|android> --session <s>`
+from the directory you opened the session in. It installs the cached build into
+that session (`--abi arm64-v8a` for an ARM Android device; `--metro <url>` also
+opens it against Metro) and never builds.
 
 Start `vp run dev:client` from `apps/mobile`, or reuse a healthy Metro belonging
 to this checkout. Open its printed development-client URL with AgentDevice
