Provides workspace command, terminal and protocol-process services. protocol handles structured subprocess communication; terminal manages interactive terminal resources. Configuration supplies the installation ceiling, and each call still needs its own authority. Closing an observer does not terminate ownership of a running process.
Live terminal screens and background-process logs come from the original worker handle. Output alone does not update the durable resource revision, updatedAt, or watchList; start, state, actual resize and final output still commit durably. Detail watches accept new output at the same durable revision. After a Host crash, orphan recovery retains the last durable snapshot, which may predate the last live output.
health (the default BackgroundTaskHealth model tool) reads the original session-owned process, including live logs when retained. updatedAt denotes the last durable resource update, not output activity or endpoint health. Logs require include_logs: true. An optional HTTP(S) URL is probed by the bound Web service under separate network permission; the process result and endpoint observation are independent. A responding endpoint proves neither listener ownership nor browser readiness. Health calls and their nested probes retain original operation receipts.
The Terminal raw output contract uses the original PTY owner and complete replay in two resource-owned anonymous temporary files. Temporary storage grows with output and is released when the original resource and all existing readers are dropped. Closing an output observer leaves the process and controller unchanged; existing sequenced control and mutation receipts retain their original authority.
