… process is a lost controller On Windows the name a rename installs can be refused to a reader for a short interval. The waiter read that refusal as an unreadable controller record and declared a running compiler lost: 10 of 40 Windows-host cross builds failed this way (#890). Records and statuses are now opened with a bounded backoff (kRecordSettle, 250 ms) while the name exists; an absent name is absent at once and a refusal that outlasts the bound is an error. The controller's state is three-valued: only an identity that names an ended process is ended; an unreadable record is unknown and the waiter keeps waiting within its existing bounds. A loss is reported with the observation that decided it. copy_atomic publishes through the host namespace like every other record of the module, so a name in Windows' long spelling stays valid. A cancelled managed supervisor writes its status, and a registration failure reaches the supervisor log. Co-authored-by: speak-agent <248744407+speak-agent@users.noreply.github.com>
