How far a self-upgrade this deck set in motion has gotten.

POST /api/upgrade answers 202 and returns immediately - see its own doc for why - so Progress is the only way a phone that asked for an upgrade learns anything about it afterwards.

Variants

Downloading

Downloading the release asset and replacing the binary. This bundles what would otherwise be two stages: kaishin re-confirms the release and downloads it inside one await with no hook to split, so from here a phone cannot tell “still checking” from “still downloading” - only that nothing has been swapped in yet. The confirmation that ran before this stage started is already known to the phone: it is what the to version in the 202 answered with.

Replaced

The new binary is in place and crate::web’s handover has been signalled, but has not acted yet.

Parking

The handover is waiting for the run in flight, if any, to reach its next node boundary. The deck answers throughout this - it is not the unreachable gap, see web::hand_over.

Restarting

The listener has been released and the successor is starting. This is the one genuinely unreachable moment, and it is meant to be sub-second - see web::bind_waiting.

Done

A successor came up and confirmed it is running the release this upgrade asked for.

Failed

The upgrade did not reach Stage::Done. detail on Progress says why.
