prompt required — there is no empty-commander case on either client. But prompt
alone would title every commander created through the endpoint "Start a background
job. The mechanics below are load-bearing..." — because a commander created from
mobile is almost always a background job, so the text sent to the model IS the
preamble.
The websocket already solved this: title is displayText ?? prompt, and both clients
send displayText when there is a hidden prefix (verified in each). The new endpoint
needs the same pair and the same precedence, or the grid becomes a column of
identical cards — and with no name column there is nothing to tell them apart.
Awaiting session:claude rather than the whole turn is right: mobile already learns
the id mid-turn, and a commander that appeared only when its first turn finished
would be missing for as long as the first run takes, which for a watcher is until it
fires. Offered to review the extraction diff.
