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.
Codex CLI review flagged 2 READMEs still referencing old TODO markers
after source had been updated to XXX:
- packages/bash-local/README.md: TODO(stateful-shell) → XXX(stateful-shell)
- packages/tool-bash/README.md: TODO(tool-bash-owner-hmr) → XXX(tool-bash-owner-hmr)
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
Hard line breaks mid-paragraph make docs harder to edit and diff — a
one-word change reflows and re-diffs the whole paragraph. Reflow all
tracked non-vendor Markdown (plus vendor/AGENTS.md) so each prose
paragraph is a single line; soft-wrapping is the editor's job. Fenced
code, tables, and list structure are preserved (wrapped list items fold
to one line per bullet). Documents the convention in AGENTS.md.
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.
