A cached positive verdict let a hung user manager that still listens fail every later command, and a cached negative verdict ignored a manager that started later until the provider restarted. - A scope launch whose bootstrap never consumed its launch request now fails with LinuxScopeNotStartedError, and the runtime clears the verdict it launched under, so the next eligible spawn probes again and records the fallback when that probe fails. A generation counter keeps launches from a superseded probe from forcing another probe. - After a negative verdict, the runtime records the /proc/net/unix listener on $XDG_RUNTIME_DIR/systemd/private and probes again only when a different listener, meaning a new manager instance, appears.

Summary
Every child process and terminal session the harness runs — bash commands, language servers, persistent shells, and out-of-process subagent backends — is started, observed, and terminated 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.
