Why a crew needs a doctor
A publish fails because a host was slow. A scan fails because a model returned nothing. A key expires. Left alone, each of those becomes a silent gap in the work. The doctor runs on every pass, recognises the known failures and applies the remedy: retry, reconnect, clear the stuck job, close the alert that was already solved.
The CTO reads the code
Some failures are new. Those go to Forge, the CTO agent, with the trace and the context. It reads the code that failed, writes up the cause and the fix, and the owner's team ships it. You see it in the record as a note, not as a broken screen.
The self-test is bug testing you never have to do
Every night the self-test calls every read endpoint for every brand and checks the invariants: the database is healthy, backups are fresh, no job is stuck, no text carries a forbidden character. What it finds becomes suggestions for the doctor and, if needed, an alert for you.
Alerts you can read
An alert says what happened, why, what was done, and what, if anything, needs you. The ones that need nobody close themselves with the reason. Only needs-you alerts and serious failures reach your inbox, at most a dozen a day.
