Carry the existing write fence across Hermes-owned spawn boundaries without
dropping board routing or changing credential policy. Grant dispatcher and
managed tool runtimes explicit task scope; align CLI task mutations with tools.
Verify real shell/CLI descendants, dispatcher startup, and supervised stdio
transport against isolated SQLite boards. This is cooperative runtime scoping,
not OS confinement.

For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
