The session did the task and stopped on make verify-device. The cause was not the server: run-plan.sh and the device tests both read BOXMAKER_MODEL, and the run's value (OpenCode's provider-prefixed id) reached llama-server as the model name. With it unset, verify-device passes 6 of 6. The copied files are identical to the plan's, and the gate prints gate: ok, 936 tests. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
