A recycled shell pid could donate an unrelated process's children to the terminal session's cleanup signalling: post-exit rescans queried processTree/processSession by numeric pid alone. The handle now captures the spawned shell's start identity at construction and adopts newly scanned members only while the root pid still carries it; already-adopted members keep their own identities, which every signal already rechecks. Regressions cover a recycled root donating an imposter child and a shell whose identity was never observable; the terminal fakes now model the root row the real /proc and ps scans include. Also from the review round: tool-pty's dependency list is re-sorted, and the LSP renderer documents the deliberate drive-letter reading of ambiguous file: URIs (display-only blast radius).
subprocess/ — subprocess capability family
English | 中文
The shared process substrate for one execution world: executable lookup, fully-specified managed child-process trees with raw or collected stdio, and one deep terminal-process primitive that owns PTY allocation, foreground groups, and provider-observable session cleanup. Command defaulting, shell semantics, deadlines, protocol framing, readiness, and presentation stay with consumers — the bash executors, LSP host, PTY shell backend, and ACP subagent backend. See the subprocess seam Agent Note.

The seam: executable lookup, ordinary managed spawns, the terminal-process primitive, handle lifecycles, and shared environment/output vocabulary |
subprocess-local (@deepseek-ai/dsh-subprocess-local) |
— | The local implementation: detached process trees, bounded collection/spill, node-pty, foreground/session inspection, tree signalling, and terminate-and-join disposal |
The service owns process lifetime across consumer reloads; consumers own what a process means (a bash command, a future non-shell runner) and every default that shapes one.
