What changed

Fix with AI on the Updates completion screen could appear unresponsive for 50 to 94 seconds while a health scan ran before the terminal opened. Launch failures disappeared because the page discarded the command output. Codex was also missing from the supported repair harnesses.

Open the terminal before scanning, show an immediate opening state, reject duplicate pending launches, and display the launch result or error. The terminal keeps scan errors visible. Rashin can now select Codex for repairs independently of its chat agent, with a model and reasoning effort for that session only. For example:

"fix": {"agent": "codex", "model": "gpt-6.1-sol", "effort": "low"}

Existing harness preferences stay the same when fix is unset. General Codex settings are unchanged.

Area

ryoku, including the Settings Hub and Rashin.

How it was tested

• Backend go test ./... and go vet ./... passed. Regression tests cover the configured Codex arguments and opening a terminal before the health scan.
• The real Updates QML page ran in an isolated headless Quickshell harness with a simulated completed update and fake terminal, doctor and agent boundaries. Invoking the button's action twice produced one launch, immediate feedback, and the expected Codex arguments. A failed terminal launcher produced a visible error and allowed retry.
• A separate offscreen Quickshell process probe confirmed a missing Rashin command returns collected stderr and exit 127.
• The repository's Hub QML lint gate and commit/push hooks passed.
• Local packages containing only the changed binary and QML were installed on an existing packaged system. Package integrity, materialized QML, service executable and repair settings were checked.
• Earlier harmless codex exec probing confirmed the requested model and low effort work. No actual AI repair ran.

The headless check invoked the button's action signal, not a pointer click. The user's live Hub button and native terminal window were not exercised. The scan timeout still applies inside the terminal. New UI strings await translation.
