The subprocess group map: the shared child-process service and its local host provider, for users and maintainers navigating the group.	package-group

subprocess/ — subprocess capability family

English | 中文

Summary

Every child process and terminal session the harness runs — bash commands, language servers, persistent shells, and out-of-process subagent backends — starts, observes, and terminates through one shared service (ctx.subprocess), with a local provider running them on the host machine. It is not a standalone product feature: the consuming capability seams decide what each process means, and command semantics, deadlines, and model-facing presentation stay with them. The group provides executable lookup, bounded output capture with spill recovery, provider-managed process ranges with disclosed weaker fallbacks, and a scrubbed starting environment for every child.

Packages

Package	Role	ctx key
subprocess	Defines the child-process service: executable lookup, managed process spawns, and real terminal sessions	ctx.subprocess
subprocess-local	Runs host processes and terminals with native managed ranges where supported and explicit weaker fallbacks elsewhere	registers on ctx.subprocess
win32-process	Owns shared Win32 bindings for sandbox and ordinary process creation, stdio, Job assignment, polling, waits, and handle cleanup	library — no ctx key

The service keeps process lifetime across consumer reloads; consumers own what a process means (a bash command, a language server) and every default that shapes one.
