Background-task ownership needs a stable home that survives a consumer HMR
reload. Add an optional `owner?: string` to `BashExecRequest` and a
required-but-nullable `owner: string | undefined` to the resolved
`BashExecSpec` (mirroring how `workdir`/`timeoutMs` are required on the spec —
a forgotten owner is a visible `undefined`, never a silently-absent property
that yields an unowned, cross-session-readable task). `resolve()` carries it
through.
Expose the stored token via a new `BashExecutor.ownerOf(id): string |
undefined` seam (ONE read path — not also on the public `BashTask`). The
executor stores and returns the token verbatim and NEVER interprets it: the
access POLICY lives in the consumer (`dsh-tool-bash`). `bash-local` stores
`owner` on its `TrackedTask` and implements `ownerOf`; unknown-id and
known-but-ownerless both read as `undefined`. Because ownership lives on the
task in the executor (disposed with the `dsh-bash` fiber), it survives a
`tool-bash` HMR reload.
Updates the StubExecutor seam test and the bash/bash-local READMEs.
Reclassify 4 markers that did not match their actual urgency per
docs/development.md:
TODO → XXX (someday-maybe, no commitment):
vendor/cordis/src/reflect.ts:250 — enhance error message
packages/bash-local/src/run.ts:248 — stateful-shell design reference
FIXME → TODO (should fix soon, not blocking release):
vendor/loader/src/index.ts:108 — merge config
vendor/cordis/src/fiber.ts:376 — internal/fiber-info
Three packages following the new capability-seam pattern (interface /
implementation / consumer, now documented in docs/architecture.md):
- dsh-bash: abstract BashExecutor service (ctx.bash) + vocabulary types.
- dsh-bash-local: local subprocesses — bash -c per call in a detached
process group, SIGTERM→SIGKILL group kills, tail-keep truncation with
full-stream spill files, model-friendly env, background task registry.
- dsh-tool-bash: the bash / bash_output / bash_kill tool schemas with
runtime arg validation and background completion notices via
agent.inject(). Non-zero exits are reported, not errored.
Design surveyed against the bash tools of Claude Code, OpenCode, Codex,
and pi (notes in the package READMEs). Permissions/sandbox stay TODO on
the tools/execute waterfall seam; stateful-shell alternatives recorded
in run.ts.
