MacProcessInspector answered the descendant tree and every member's liveness with its own `/bin/ps` fork, so one readiness poll cost N+1 full table reads for N tracked descendants. With execFileSync on that path and a 50 ms poll interval, any command spawning two or more children saturated the host event loop until it exited. ProcessInspector.snapshot() now returns one ProcessSnapshot that answers tree, session, and alive from a single observation, and signalProcess takes the caller's observation so its PID-reuse fence does not re-read the table per member. |

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, whole-tree termination, and a scrubbed starting environment for every child.
Table of Contents
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 those process and terminal spawns on the host machine | registers on ctx.subprocess |
win32-process |
Owns the shared Win32 bindings for restricted process creation, stdio, Job assignment, 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.
