installer-script+desktop -> hermes-desktop-app-update failed on
"The submitted draft must clear before the idle control proves completion"
(15s predicate), while the failure screenshot shows a healthy, configured app --
Gateway ready, Mock Model selected, and the exchange COMPLETED
("Hello from the mock inference server! The full boot chain is working.") with an
empty composer by capture time.
So the submit was accepted and QUEUED, not rejected: v2026.8.31's composer routes
a submit to its queue while a turn is in flight (its own comment: "busy submit
routes text to the queue instead of a steer"), so the draft legitimately stays
visible past 15s and clears once the queue drains. That is why this leg differs
from its sibling, whose app the capture step builds from HEAD.
The draft-clear poll now uses 90s like the mock-receipt and reply polls beside it;
those still enforce delivery, so a genuinely stuck composer fails there instead.
