Address review and cut ceremony: the adapter no longer models help/version/
errors as DshInvocation members. Commander owns those under exitOverride — it
prints usage or the diagnostic and one try/catch in parseDshArgs turns the
thrown CommanderError into process.exit with the intended code. bin.ts drops its
help/version/error cases; the union is the three real modes.
Domain checks bail via command.error(print + exit 1): --prompt rejects an empty
task or a stray config/--resume, empty --resume= fails loud, and --host/--port
are validated. A repeated --resume or a flag captured as a value is Commander's
standard behavior, left alone (a bad id fails loud downstream). dsh --help
discloses web via addHelpText. Net: args.ts 185 -> 112 lines.
Also fixes review nits: built-bin e2e resolves on `close`; the /resume handoff
uses `dsh --resume=<id> -- <config>` so a config named `web` stays a positional;
and stale prose (cordis.yml comment, app-boot module doc + duplicate JSDoc,
ui/README, two feature notes, an agent-loop test name) tracks the shipped state.
Removes tui-demo's now-dead plugin-include dep and vendor/loader + app-boot
tsconfig references.
Integrate the Commander argument adapter with master's safe session-resume
feature and dsh web --dev flag.
- args.ts: add --dev to the web parser.
- tui.ts: keep master's process.execve in-place resume handoff, but take the
adapter's parsed (config, resume); inject the resume id through boot's
prepare(ctx) hook via ctx.provide(RESUME_SESSION_ID_KEY, id) instead of the
RESUME_SESSION_ID env var; rebuild the re-exec argv as `dsh --resume <id>`.
- app-boot: drop master's replaceResumeArg (no longer needed) alongside the
already-removed parseResumeArg; add RESUME_SESSION_ID_KEY.
- the four tui-agent/cordis configs read the ctx-provided resumeSessionId via a
typeof-guarded !!js expression, so resume needs no env var.
- web.ts: keep master's client roster and --dev watch, take parsed host/port/dev.
Master's log-backed session-title capability already titles sessions durably
(deterministic fallback in the spine, optional model providers). Remove the
TUI's own autoTitle generation — the latch, prompt, cap, and llm stream call —
and keep the terminal rename: the TUI folds the logged title on mount and sets
'<session title> — <configured title>' on every accepted session/title event.
The tui-agent example and the scripted PTY fixture mount
session-title-first-message-llm so titles stay model-made; the scripted
adapter's tool-less branch now answers that provider's auxiliary request.

Replace /mode [name] with same-named no-argument commands such as /plan. Update the TUI and ACP snapshots, and validate mode names against command syntax.
Delete packages/ui/stdio and examples/repl-agent; rename stdio-demo to
@deepseek-ai/dsh-tui-demo (TUI-only, refuses pipes before Loader boot).
tui-agent owns the coding composition inline; echo-agent and the CI demo
smoke move to the one-shot cli-demo bin, which gains -p/--prompt. The
UI-independent with-key e2es move verbatim to tui-agent. SDK wizard's
'stdio' interface becomes 'tui'. PTY testing stays confined to TUI
surfaces; all other subprocess tests ride pipes.

Four ds-review-bot findings:
- examples/tui-agent composed dsh-mode without the now-required
modes.plan.section, so the TUI leaf failed at Loader startup (the keyless
smoke only asserts the banner and missed it); graft the same deployment
plan instructions the ACP leaf carries.
- The prompt-submit and turn-continuation flushes ran before next(), so a
session/set_mode arriving while a downstream async listener (the shipped
hooks listeners' shape) awaited applied one request late; both listeners
now prepend and flush after next(), matching the request-error wrapper,
with a regression test pinning the ordering.
- An HMR unload during the exit_plan_mode review let a later approval write
into the disposed service and claim an exit whose flush could never land;
the execute path now checks the fiber lifetime after the await and fails
the call (the mode stays plan; the model re-presents).
- resolveConfig accepted empty/untrimmed mode names that list()/ACP then
advertised while the package invariant rejected their selection,
desynchronizing the picker; names are validated non-empty and trimmed at
load, the same shape the invariant enforces.
Master arrivals re-grafted onto the plan-mode surfaces:
- Package invariant runtime contracts: every package owns ./invariant —
added the dsh-mode companion (mode/set payload validation: non-empty
trimmed name), its unit spec, exports/peer wiring, and the mode group in
the tsconfig invariant paths glob.
- Interception waterfalls gained an AbortSignal parameter
(agent/prompt-submit, agent/turn-continuation) and ToolExecutionInput.signal
became required: listeners and test dispatch updated; the exit tool now
forwards exec.signal unconditionally.
- TUI question dialog: master's position/unanswered header layout kept,
the plan-review detail block re-grafted between question and answers.
- LSP capability family arrived: lsp tool joins the catalog pin, dsh-lsp
examples deps beside dsh-mode; lsp-definition snapshot refreshed with
the mode command and modes advertisement.
- docs/architecture.md and packages/README.md regenerated tables re-grafted
(ctx.modes row, mode package row) and condensed within word ceilings.
- examples/acp-agent cordis.yml: kept the deployment-owned plan instructions
(incl. the conversational-agreement sentence) beside master's routed-model
compaction comment; snapshot expected outputs refreshed keyless and noise
fixtures restored.
The master merge brought the tool registry's per-scope restriction layer
(tools.restrict), which makes dsh-mode's prepend assemble filter a duplicate
enforcement shape: it re-implemented the registry's SDK-section rendering
(renderToolsSdk + the RUN_CODE_NAME exclusion) and hid the exit tool from
prompts only — dispatch stayed open and the execute-time re-check was the
real gate. The service now reconciles a per-agent deny restriction on
agent.ctx at agent/created and at every boundary flush, so wire schemas, the
Code Mode tools:sdk section, AND dispatch resolve exit_plan_mode through the
one registry view (a default-mode call answers UNKNOWN_TOOL, byte-identical
to a no-dsh-mode deployment). The execute-time folded-mode re-check stays as
defense in depth for a direct foreign mode/set append no boundary has
reconciled yet.
Two zero-consumer surfaces removed per the pre-release stance:
- AgentOptions.mode creation seeding (declaration merge + agent/created
listener); a caller selects through set() before the first turn, and the
deferred subagent inheritance returns together with its consumer.
- The dropped-definition boundary notice (droppedNoticed + narration):
custom mode definitions have no production consumer, so nothing can be
dropped; fold-to-default degradation is unchanged.
The stdio removal had left plan mode ACP-only while docs still claimed a
/mode command. dsh-mode now registers /mode on the plugin-owned command
registry through an optional ctx.inject(['commands']) child (type-only peer
edge on dsh-commands), so the TUI and the ACP slash-command surface both
gain it; examples/tui-agent composes dsh-mode. ACP/TUI expected outputs
refreshed keyless for the available_commands_update delta.
Docs updated in place (mode READMEs, the plan-mode Agent Note's realization
sections); catalogs and graphs regenerated.
Name the runnable leaf for the line-oriented front door it owns, matching the existing tui-agent and acp-agent organization. Move the complete config, Code Mode overlay, tests, metadata, and generated composition graph together, then update every loader path and repository reference.
Keep the shared model identity independent of its terminal front door by phrasing the persona as a coding-agent role rather than retaining the retired leaf name. Regenerate graph and tool catalogs and re-record each affected bilingual pair so derived documentation cannot point at the removed path.
