The probe child now runs with the harness's credential-shaped variables scrubbed — the one rule every spawner uses, now defined in dsh-launch-environment and re-exported by dsh-subprocess — and its report is the one message echoing a per-run token the child removes from its environment, together with process.send, before importing anything. The failure text keeps the last 16 KiB of stderr instead of every byte, and the probe settles only on the child's close, so no pipe or channel outlives the call.

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.

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.
