Device testing checklist

Simulator verification covered connect/disconnect, transcripts (text mode), tasks panel, and the hardening pass. The items below need a real iPhone on the LAN (https://192.168.86.2:9178) because mic input, WebRTC capture, and audio session behavior don't work in this simulator environment (CoreAudio -4010, 0 input channels).

Setup: recheck device availability and signing, then build/install with Xcode or the installed XcodeBuildMCP skill workflow. The phone was paired and the Nearlight build launched successfully on September 12; that does not prove today's availability or a still-valid provisioning profile. Verify the server certificate pin after an actual certificate rotation, not automatically after every container restart.

For each check, record date, source revision, device/iOS version, backend/model, observed result and supporting logs. Leave unchecked items unqualified; installing the app or passing a simulator state test is not equivalent to hearing a reply.

1. Mic input with real speech

• Start → agent joins → mic enables without -4010.
• Speak: Lightwell/status transitions to listening; mic meter moves with voice level.
• Stop speaking, wait >2 s while agent is silent → thinking chip appears.
• Agent replies: state goes to speaking (remote audio drives it), TTS audible.
• User transcript finals arrive in the list with correct role/timestamps.

2. Barge-in

• While the agent is speaking, start talking → conversation continues without a "barge-in" glitch; state returns to listening/thinking as expected.
• Switching to Type leaves microphone capture off and text messaging usable.

3. Wake lock (screen off)

• During an active conversation, observe that auto-lock is suppressed (isIdleTimerDisabled prevents the device from locking due to inactivity).
• Note: isIdleTimerDisabled does not prevent a user from pressing the side button to lock the device. It only disables the automatic idle timeout.
• After hang-up, auto-lock returns (idle timer re-enabled).

4. Audio interruption (phone call / Siri)

• Mid-conversation, trigger an interruption (incoming call or "Hey Siri").
• On end (with shouldResume), mic and conversation resume automatically.

5. Mic permission denied fallback

• Deny microphone permission in iOS Settings for the app, relaunch.
• Start → session reaches ready despite mic failure (non-fatal); a visible error explains the problem and offers iPhone Settings recovery; Type remains usable.

6. General device sanity

• Connect / hang-up / reconnect matrix (3×) — no crashes, state resets cleanly.
• Change server URL in Settings while idle → session recreates without crash.
• Reconnect banner appears on network loss mid-call; recovers on return.
• Voice/model picker changes take effect live on the agent and survive relaunch.
