Chinese counterpart translated per the terminology table and the
2026-07-18 TUI note's register; switcher lines added on both sides; pair
recorded. doc-sync 24/24.
Regenerate config-catalog for the llm-replay paceMs row; condense the
testing.md web-lane entry to pointer form and raise its ceiling 1020->1060
(the two-sentence tier entry for a genuinely new surface does not fit the
old ceiling after relocation-first trims); internalize two harness helpers
knip flagged (rawSessionLog/normalizeAria are module-internal).
Simplify the Commander adapter now that behavior can change: dispatch a leading
`web` token to its own parser instead of a subcommand of the root program, and
read opts()/processedArgs after parse() instead of action closures with a
mutable holder.
This removes enablePositionalOptions(), the parent-option leak guard, both
action closures, and the --resume/--prompt argParser threading. Behavior
changes: `dsh -p x web` is a headless prompt (extra positional dropped),
`dsh web -p x` fails loud (web has no -p), and a repeated --resume is natural
last-wins. The two real fail-loud invariants stay as post-parse checks: an empty
--resume= id (agent-loop treats '' as no-resume) and an empty -p task.
Trims args.spec.ts to the routing/fail-loud/help behavior that matters; the
tui-agent keyless PTY smoke still covers bin.ts dispatch end to end. Net ~114
fewer lines across adapter and tests.
testing.md gains the web browser snapshot tier entry (divergent
DSH_SNAPSHOT=... test:web commands) and names apps/web/tests/snapshots/
as the web surface's snapshot home. The GUI testing note's tier map and
lane map gain the e2e scenarios (both languages, pair re-recorded) and
drop the stale verify-session-real references (those scripts left with
the missions/ tree). packages/client/AGENTS.md check ladder covers the
wire-carriage trigger and refresh/record commands. acp-snapshot README
stops claiming the whole package is ACP-specific — its normalizers are
transport-neutral with three consumers now. vitest.web.config.ts header
carries TODO(ci-browser) with the staged-reversal pointer.
The design-study Agent Note moves proposed/ -> implemented/ rewritten in
present tense: all review decisions recorded (llm:false seam over the
placeholder-key hack, providers-mode replay, whenIdle barrier stack,
single aria golden + anchors, TUI-style inline modes over a suite
factory, scrub-only header stance, CI deferral) with re-entry triggers
under Deferred.
apps/web/tests/harness.ts boots the real web assembly in-process
(startHost llm:false -> installLlmReplay providers-mode -> mountWebPlugins
-> startWebServer) under DSH_SNAPSHOT replay/record/refresh. Barrier
stack: in-process turn/end -> agent.whenIdle (covers the persistence
flush) -> browser settled-poll. Seeding goes through the real persistence
API (semantic-checkpoint precedent); record harvests fixtures from live
session memory and tokenizes {{sessionId}}/{{cwd}}; refresh is the sole
golden writer. Console tripwires fail scenarios on reconnect/gap-repair
self-healing; harness close asserts full replay-fixture consumption.
Scenarios, each with fixtures recorded against THIS assembly via a live
model run: replay-round-trip (real composer -> real bash echo -> settled
markdown + aria golden + world-state event asserts) and seeded-history
(cold sidebar list -> implicit resume on open -> history tool cards from
the log, zero model calls). apps/web/tests are host-plane programs:
excluded from the client-registered apps/web project, included in
tsconfig.host.json (one program cannot hold both Context merge sides).
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).
