R76's decision 4 planned a nightly run on two phones attached to emi, and two phones will not be attached there for months at a time. The plan now asks for an on-demand run instead, made whenever two phones are at hand and before each peer phase closes, beside the recorded home run across the other machines. This PR is that run, stacked on #142.

connetto-android-proof --peer-serial <second> --every-join builds, installs and signs both phones in once, then joins the second phone to the first one's hotspot by the typed form, by the Bluetooth beacon and by the pasted WIFI: payload in turn. It brings the phones back to rest after each join, records a failed join and goes on to the next, and writes a summary.txt naming the commit and each step's result and time beside the screenshots.

The first run on two Galaxy A35s passed the single-phone proof and all three joins in about four minutes, and left both phones on their usual network with Bluetooth off.

📝 Walkthrough

⚠️ A high-level summary could not be generated for this review. CodeRabbit will regenerate it on the next update, or you can request a refresh with @coderabbitai summary.

Walkthrough

The Android proof harness can run the form, beacon, and payload peer joins in sequence. It records each route’s duration and result, captures route-specific evidence, restores the phones between joins, and writes summary.txt. The implementation plan now specifies an on-demand two-phone run.

Changes

Android peer join proof

Layer / File(s) Summary
Route selection and run reporting
crates/connetto-test-harness/src/bin/connetto-android-proof.rs
The --every-join option selects the form, beacon, and payload routes and requires --peer-serial. The harness times the single-phone proof, collects peer join reports, writes summary.txt, and returns an error if a join failed. Tests cover passing and failing joins and a setup failure.
Peer route execution and restoration
crates/connetto-test-harness/src/bin/connetto-android-proof.rs, plans/master-implementation-plan.md
The harness runs each selected route independently, records failures, and captures route-specific screenshots. It restores phone state between joins. The plan criteria specify an on-demand two-phone run and retain the recorded home run requirement.

Merge Risk: 🔵 Low · up to 2425c

A failed join in the two-phone proof run can leave a phone with Bluetooth on or on the wrong network. Later joins in the same run can then fail as well, which weakens the run's per-join results. This affects only the developer test tool, so the risk is bounded, but fix the cleanup paths before relying on the summary.

- Around line 795-798: Update the error flow in one_join so a failed hosted
operation does not return before network cleanup: when offer_ssid is known,
still call restore_joiner_networks and wait for the joiner to return to
usual_ssid. Preserve and return the original hosted error if restoration also
fails.
- Around line 764-769: In one_join, prevent bluetooth_on failures in the Beacon
setup from returning early; retain the enable result and use the existing hosted
restore path to turn Bluetooth off on both phones regardless of enable or
hosting outcome. Run hosting only when Bluetooth enabling succeeds, and preserve
the existing join result handling.
