Address ds-review-bot: the bounded-request-recovery Agent Note stated the
shipped default carried four transient codes, and the llm-streaming contract
omitted the new cross-adapter empty-response classification. Update both
current-state contract docs to the five-code default and cross-link the
empty-response bug-fix note.
Replace the dsh CLI's three hand-rolled parsing idioms (raw argv[0]/includes
dispatch in bin.ts, per-mode node:util parseArgs in headless.ts/web.ts, and the
bespoke parseResumeArg scanner in dsh-app-boot) with a single Commander adapter
in apps/cli/src/args.ts. parseDshArgs resolves argv into a discriminated
DshInvocation union; bin.ts switches on the mode and dynamic-imports the chosen
module, which now consumes already-parsed values.
- web is a real subcommand; --host uses choices and --port an argParser range
check, moving validation into the parser.
- --resume rejects empty and repeated forms; --prompt rejects empty; a config
positional after --prompt and a root flag placed before web fail loud.
- adds --help/--version; removes parseResumeArg from dsh-app-boot.
- new apps/cli/tests/args.spec.ts (apps/*/tests added to vitest include,
apps/cli/tests to tsconfig.host.json); the tui-agent keyless PTY smoke covers
bin.ts dispatch end to end unchanged.
The fake terminal retains earlier autocomplete frames, so the directory follow-up assertion could pass before the scoped lookup completed. Wait for the quoted file mention to be applied before submitting.
A well-formed provider stream that ends with finish_reason stop and zero
content blocks previously became a successful empty assistant message: the
turn completed silently, and drivers like goal-session counted the no-op
round. Both adapters now map that degenerate completion to a finish
{kind:'error'} with the new canonical EMPTY_RESPONSE code from dsh-llm, and
dsh-llm-retry adds the code to its default retryable set, so the existing
closed-step recovery path retries it and fails loud once the budget is
exhausted.
Covered by adapter unit tests, an llm-retry default-policy test, and a new
authored keyless ACP snapshot (empty-response-retry) with a deterministic
1 ms zero-jitter retry overlay.
BootHostOptions.llm: 'deepseek' | false — false mounts no adapter, boots
keyless, and leaves the llm capability seam open for the embedder to fill
on RunningHost.ctx (now the third sanctioned ctx use, JSDoc + README
amended); an unfilled seam fails loud with NO_ADAPTER at the first stream.
dsh-llm-replay grows two additive surfaces for the web browser e2e lane:
paceMs (validated per-chunk delay so a real transport shows incremental
delivery; abort during a pace wait cancels promptly) and a ReplayHandle
return — dispose() plus assertConsumed(), the teardown check that every
recorded script bound and drained, converting silent fixture underruns
into diagnostics. Existing callers updated; config catalog regenerated.
Design study for a deterministic, keyless browser e2e lane over the real
assembled web chain (chromium -> SSE/HTTP wire -> apiproxy -> agent loop ->
persistence), replayed through dsh-llm-replay from recorded session-log
fixtures, with aria-tree goldens plus in-process world-state assertions.
Synthesized from an OSS prior-art survey (LibreChat, ai-chatbot, lobe-chat,
OpenHands, cline, aimock...), a repo seam deep-dive, and three adversarial
critiques (doctrine, flakiness, YAGNI). Records the settled shape (no new
package, no suite factory, seed via the real persistence API, whenIdle
barrier stack, no transient-DOM assertions) and the open questions (LLM
seam, Loader-izing dsh web, header pin, golden breadth, settled signal).
