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).
The tasks/ family now matches the capability-seam shape: @deepseek-ai/dsh-tasks
keeps the abstract TaskService (ctx.tasks contract, vocabulary types, snapshot
invariant companion) and the new @deepseek-ai/dsh-tasks-local carries the
process-local registry (LocalTaskService: in-memory store, settlement,
owner-cleanup effects, teardown, TASK_WAIT_TIMEOUT). Compositions and test
harnesses now load dsh-tasks-local; producers, TaskKindMap merges, and
dsh-tool-tasks keep importing the seam only.
Producer misconfiguration diagnostics name dsh-tasks-local because loading the
implementation is the fix. The registry behavior suite moves to tasks-local;
the seam keeps a stub-subclass registration test and the probe-based invariant
suite.
