The desktop app is 0.3.2, and its runner updates are fast, seen and only ever g1t's. The app now trusts a g1t-runner release only when its manifest's Ed25519 signature, latest.json.sig, checks out against g1t's runner release key, which is built into the app (the public half of RUNNER_RELEASE_PUBLIC_KEY, kept in runner/native.rs, where development builds have it too; G1T_RUNNER_RELEASE_KEY overrides it for a g1t with its own key), as the runner already did with its own updates. A manifest with no signature, or one that doesn't check out, is refused and nothing in it is used: the runner keeps the version it has and says "Update refused: not signed by g1t", or, with no runner installed yet, "Not running: the runner's release isn't signed by g1t", each with why and what to do. It looks every hour rather than every six, on a thread of its own so the runner is looked after meanwhile, and what it finds waits, downloaded and checked, until each kind of job is idle, then goes in kind by kind, never cutting a job short: Linux jobs take the release's image (sandbox update) as soon as they have no job, while Windows jobs, whose runner is the program itself, are stopped after their job (sandbox down --only windows --drain), the program is replaced and they start again, the other kind running on throughout; a runner in Docker or on the computer stops between jobs and starts on the new one. The program there is moved aside rather than overwritten, so a status the app is asking at that moment can't stop it. Each kind of job's card in Settings shows its runner version, when the app last looked ("Checked 12 min ago") and a newer one waiting ("0.3.2 ready, installs after this job", "Installing 0.3.2"), and "Check for runner updates" beside the computer's name looks at once and installs what it finds, even with "Download updates by themselves" off, which otherwise stops the hourly look. The desktop report carries the same (snake_case: the diagnosis's update, with checked_at, ready and note, and each kind's update), so the Runners page's Desktops cards show it, "Checked" with how long ago, and this computer's row has the button too. All the words are diagnosis.rs's. The desktop guide says how updates work, what each card shows, the new troubleshooting rows and where the release key lives. Tests cover the signature with a key pair of their own and with release 0.3.0's manifest and signature as g1t.sh published them, kept byte for byte (.gitattributes), the wording, the cards and the report.
