New package on the domain data form: one session_projcache record per
session (key → {stateVersion, observedSeq, state}), landing beside
workspace.json under the shipped json backend. Write policy: two mandatory
points (turn/end + session disposal) with count/interval throttling between
them (both Config fields required — flush cadence is a deployment choice);
every background write is fail-soft (log + stay stale, self-heal on the
next write or cold read). coldSnapshot(id) runs the read ladder — cached
rows + persistence readFrom from the registry's anchored restore floor +
registry restore + fail-soft write-back — detecting crash-repair-shrunk
logs via the one-below anchor and degrading to a single full re-read.
Mounted in apps/cli/cordis.yml (writeEveryEvents 200 / writeIntervalMs
5000).
directory-picker-browse becomes dual-face: its browser half fills
ui-workspace's two directory-flow holes with the Select Workspace Directory
dialog (figma Harness 813-23126 family — Miller two-column view, breadcrumb
with click-to-edit path zone, nested New-folder dialog), driving the node
half's host.listDirectory/host.createDirectory and owning its locale
namespace (directory-browser, zh default / en). The dialog moves here from
ui-workspace wholesale — the trigger surfaces keep only the flow-hole owner
conversation.
apps/cli flips its one directory-picker row -native -> -browse, swapping the
host backend and the client interaction together; picking now works for
remote deployments out of the box. The keyless workspace-flow snapshot boots
the browse bundle and drives menu -> dialog -> Documents -> project -> Open
against the fixture tree.
ui-workspace's two trigger surfaces each declare a single-kind directory-flow
hole (conversation.hero.workspace.directoryFlow / sidebar.workspaces.directoryFlow,
same owner contract) and keep only the trigger and the adoption: the Open-local-
folder entry renders while the surface's hole is occupied, and the occupant
reports one picked path per open through the hole's owner conversation
(open/busy/onPicked/onCancel/onError).
directory-picker-native becomes dual-face: its browser half fills both holes
with a renderless occupant driving host.pickDirectory, so the cordis.yml row
that mounts the backend also composes the client interaction — a mismatch is
impossible and a second flow package fails at client load.
With composition wiring both sides, the host.describe.directoryPicker
advertisement and the client's kind branching lose their last consumer:
the field, WorkspacesService.directoryPickerKind(), the DirectoryPickerKind
wire type, and the picker's per-open describe read are deleted. The connection
fixture now serves a deterministic pickDirectory path so the keyless snapshot
drives the full pick-then-adopt flow. ui-workspace's hand-rolled declaration
deferral is replaced by the deferRegistration helper it duplicated.
Add @deepseek-ai/dsh-tmux-context: an opt-in per-turn context plugin that
reads which tmux session/window/pane this agent process runs in (plus the
window layout tree) via the ctx.bash seam, and injects it as one durable,
source-attributed user/message when the location changes.
- Pull on the first step of each turn; no tmux hook or background process.
- Detect a real pane by tty, not $TMUX_PANE alone: a terminal launched from
a tmux shell inherits $TMUX/$TMUX_PANE from that ancestor, so the command
also matches the pane's #{pane_tty} against this process's controlling
terminal and emits fields only on a match.
- No-op outside a real pane, without a bash executor, or on a malformed
reading.
- Own location and layout only: no pane sizes, no sibling-pane scraping.
- Unit tests at 100% per-file coverage, plus a keyless Loader e2e with a
mock bash provider so it replays without tmux.
- Agent Note: 2026-07-27-tmux-location-context.
master's toolcall-open extracted runNativeCommand inside apiproxy for the
openPath opener while the picker seam had moved the native chooser (its other
consumer) into directory-picker-native; after the merge the two packages each
carried a verbatim copy. The runner now lives in packages/util/native-command
(zero-dependency library, per the util-group contract) and both native
integrations depend on it.
The browse interaction also presents a dialog (the in-app modal), so 'dialog'
failed to discriminate the two capability kinds; 'native' names where the
chooser runs. Package directory-picker-dialog -> directory-picker-native, kind
'dialog' -> 'native', with every seam/gateway/client/doc reference updated and
the seam Agent Note's naming rationale rewritten to match.
The web GUI's folder picking was hardwired to one interaction: a native
OS chooser compiled into the gateway, unusable for remote deployments
and swappable only by editing apiproxy source.
Directory picking becomes a three-package capability seam in
packages/host: ctx.directoryPicker returns a discriminated capability —
dialog (the extracted native chooser; host-display only) or browse
(new: one-level listing + child creation over Node stdlib, hidden flags
host-stamped, symlinks followed, ancestry crumbs; remote-capable). The
gateway injects the seam, advertises the kind via
host.describe.directoryPicker, serves host.listDirectory /
host.createDirectory under browse, and answers
directory-picker-unavailable across kinds. cordis.yml is the swap
point; apps/cli keeps dialog mounted, so behavior is unchanged until
the in-app browser PR flips the default. The connection fixture serves
a deterministic browse tree; WorkspacesService gains the browse calls
the browser UI will drive. Decision record:
.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md
Every scaffold-importing e2e compiles on the host plane, so the new file
goes in tsconfig.host.json's include list and apps/web/tsconfig.json's
exclude list. Without both, tsc -p apps/web/tsconfig.json fails with
TS6059/TS6307.
The group's convention is package suffix == provider default
(subagent-acp/'acp', subagent-spawn/'spawn', subagent-fork/'fork'), and the
provider default became dsh-sdk in the last review round — so the package
follows: @deepseek-ai/dsh-subagent-dsh-sdk at
packages/subagent/subagent-dsh-sdk, plugin name subagent-dsh-sdk,
diagnostics prefixed subagent-dsh-sdk:. The dsh echo has precedent
(dsh-llm-deepseek). Directory, fixture path, knip/tsconfig/examples
registrations, catalogs, READMEs (en+zh), and the Agent Note follow; the
sdk-client dispose ladder moves to its own module (src/dispose.ts) with the
deterministic FakeChild tier tests restored alongside it.
Master's #660 replaced dsh-subagent-subprocess with the dsh-subprocess
capability seam (ctx.subprocess + scrubbedParentEnv, tree-scoped teardown)
and moved subagent-acp onto it. Convergence for this branch's packages:
- The shared out-of-process provider vocabulary this branch had grown in
the deleted library (NO_START_CAPABILITIES, assertPositiveFinite, cwd
resolution, settleRunResult, subprocessRunHandle) moves into the subagent
seam package as out-of-process.ts — it enforces subagent-seam contracts,
not process mechanics, and both out-of-process backends now import it
from there (subagent-acp keeps master's shape otherwise).
- subagent-sdk spawns THROUGH the SDK client (the subprocess README's
documented exception for SDK-managed transports) and now applies the
seam's scrubbedParentEnv() + explicit-env merge in place of the deleted
buildChildEnv.
- sdk-client inlines the EOF→SIGTERM→SIGKILL ladder as private helpers (it
runs outside any harness context, so it cannot ride ctx.subprocess).
- The child harness fixture gains the now-required dsh-subprocess-local
entry for bash-local; the fixture cordis.yml keeps exercising the
shipped provider default.
Resolutions: regenerate the conflicted generated docs (cordis services
catalog, event-producer-consumer, module-graph); take master's
packages/README pair and re-insert the telemetry row on both sides;
re-record the README and session-doc translation pairs.
- @deepseek-ai/dsh-sdk-protocol: extract the line transport from dsh-jsonrpc
and name the request/result/notification wire types both ends share; error
responses preserve wire code/data via JsonRpcResponseError.
- @deepseek-ai/dsh-sdk-client: TypeScript twin of the Python SDK — spawns the
dsh-jsonrpc-agent runtime as a subprocess, drives stdio JSON-RPC turns
(DeepSeekHarness high-level API + HarnessClient protocol client), scopes
notifications to session trees client-side, and reaps the child through the
shared subprocess dispose ladder.
- @deepseek-ai/dsh-subagent-sdk: out-of-process subagent backend driving a
child harness runtime through the TS SDK; shares cwd resolution with
subagent-acp via new dsh-subagent-subprocess cwd helpers.
- Keyless unit suites drive real subprocesses (scripted fake runtime peer);
100% per-file coverage on all touched packages.
Two new keyless scenarios for the functionality master gained since this
lane's base (#644 websettings, #643 workspace browser rework), both zero
model calls:
- settings-chrome: the modal shell (sidebar-foot trigger aria states,
role=dialog, aria-current section switch to the deliberately empty
Models, Escape + close-button paths, dialog aria golden); the Appearance
row as the REAL theme gesture — retiring lifecycle-chrome's
TODO(web-theme-gesture): clicking 深色 runs aria-pressed -> persisted
dsh.theme -> body[data-ds-dark-theme] -> alias-token flip, survives
reload, and 'system' follows the emulated OS scheme both ways; the
Language row switches the settings-scoped copy to English (dsh.locale
persisted, survives reload) and restores zh. Intentional reloads tear
the SSE stream, so the spec drains exactly its own reconnect warnings —
the tripwire still fails on unexpected connection loss.
- workspace-management: create-by-name twice through the region-header
dialog (host-durable via ctx.workspace.list()); rename end to end —
hover-revealed row menu (the button is display:none until the row
hovers), duplicate-name pre-check (inline role=alert + disabled primary
before any wire call), then workspace.rename through the real RPC,
row update, host durability, reload survival; the flat 'In one list'
view (section label flips, group headers drop, dsh.workspace.view
persists across reload, grouped restored); the session hover card
(dwell to open, closes on pointer leave). The one session row reuses
seeded-history's committed seed — no new recording. Deliberately not
driven: the inert menu rows and drag reorder (deferred in the note
with re-entry triggers).
Agent Note gains scenarios 8-9 and the drag-reorder deferred item in both
languages; llm-replay README's zh side catches up with the { patches }
paragraph; pairings re-recorded.
Resolutions: regenerate docs/capability-seams.md (the only conflict);
master widened the bilingual pairing scope to package READMEs, so this
merge adds the Chinese counterparts and i18n records for the three
telemetry READMEs and patches packages/README.zh.md with the telemetry
group row.
Review direction (tianyicui, PR #660): in a stacked PR, change all other
process-running places to use the new service.
- lsp-local: LspConnection spawns through ctx.subprocess (piped protocol
streams + a no-spill collected stderr tail); its private process-tree
helpers (POSIX group signalling, Windows taskkill, liveness polling) are
deleted in favor of the seam's handle verbs, and its buildChildEnv now
rides scrubbedParentEnv (LSP children also stop inheriting stale DSH_*).
The plugin injects 'subprocess'; compositions/tests mount
dsh-subprocess-local.
- subagent-acp: the ACP child spawns through the seam (piped ndjson streams,
inherited stderr); spawn failure surfaces through done-rejection into the
same startup race; disposal is handle.dispose with the plugin's configured
graces. dsh-subagent-subprocess is DELETED — its dispose ladder and scrub
are the seam's, and the isolated-config-dir helper had no consumer.
- mcp-client, pty-local, sdk-helper: adopt scrubbedParentEnv as the one
scrub definition (their spawns stay put by ownership: the MCP SDK and
node-pty own those calls; the SDK wizard runs outside any composition).
- Coverage: per-file 100% over every touched src file, with each v8 ignore
carrying a platform or contract reason; new suites cover stdio
dispositions, the dispose ladder tiers, injected-win32 tree semantics,
waitForExit, settled-kill/terminate no-ops, and spawn-failure disposal.
- Docs: consumer-migration Agent Note (en; zh follows in this PR), seam note
updated in place, subprocess.md rewritten for the reshaped vocabulary
(type-equiv re-registered), READMEs and SERVICE_ROLES updated, taskkill
added to knip ignoreBinaries.
Review feedback (tianyicui): 'process' is a poor service name. The family is
now packages/subprocess/ — @deepseek-ai/dsh-subprocess (ctx.subprocess,
abstract SubprocessService, Subprocess* vocabulary) and
@deepseek-ai/dsh-subprocess-local (LocalSubprocessService) — renamed
throughout code, compositions, docs (en+zh, pairs re-recorded), catalogs,
and gates. 'subprocess' is the precise term for managed OS children (the
Python-stdlib sense), avoids colliding with Node's global process object,
and reads as one system beside dsh-subagent-subprocess.
ds-review-bot findings addressed:
- kill() on a settled handle is now a no-op (no signal to a possibly-reused
pgid, no referenced grace timer delaying exit); pinned by a spy test.
- The moved DshEnvironmentKey/DshEnvironment/CollectedOutput types get
drift-checked type-equiv blocks on the new subprocess.md page, restoring
their manifest registration.
- subprocess.md is registered in the core.md sub-page index (en+zh).
New process/ capability family: @deepseek-ai/dsh-process owns ctx.processes —
abstract ProcessManager.spawn(spec) over a fully-explicit ProcessSpawnSpec —
plus the shared DSH_* managed-environment and CollectedOutput vocabulary;
@deepseek-ai/dsh-process-local carries the former bash-local run.ts plumbing
(detached groups, tail-keep spill-backed output, credential scrub, kill
escalation, kill-and-join disposal) with no config of its own.
dsh-bash-local becomes a consumer: it keeps command defaulting, the fused
deadline timedOut/aborted classification, the model-friendly terminal env
(now merged through the ordinary env channel), and the [stderr]-marked
background read merge, and spawns through ctx.processes. Background-process
lifetime moves to the manager, so an executor reload no longer kills live
background work; a background spawn failure is injected once into the read
path instead of being buffered as fake stderr. dsh-bash re-exports the moved
vocabulary so bash consumers keep one import root; dsh-bash-sandbox only
redeclares the inherited inject.
Every composition loading a bash executor now loads dsh-process-local (CLI,
examples, python bundled runtime, create-sdk bash feature, inline test
configs).
One tiny recorded text turn drives three whole-page concerns:
- workspace flow over the real wire: the empty-state hero's first send
materializes a real Workspace + Session (the jsdom workspace-flow suite
pins this state machine over the fixture client; this scenario pins it
through HTTP RPC + SSE + the gateway). Durable proof: the session
header's cwd is the create-by-name target <workspaceRoot>/workspace.
Adds the hero waiting-state aria golden.
- reload recovery: collapse the sidebar (persisted dsh.layout.panels),
page.reload, and the surface comes back whole from persistence alone —
layout collapsed, selection restored (dsh.sessions.current), the
recorded turn re-rendered from session.history with zero model calls
(the drained replay cursor makes any stray request fail loud at close).
- dark mode: no product control flips the theme yet, so the scenario
drives the ThemeService's entire DOM contract — body[data-ds-dark-theme]
— and pins the shipped cascade: the alias token flips, a painted surface
repaints, and removing the attribute restores the light sample exactly.
TODO(web-theme-gesture) upgrades to a real settings control; no theme
golden per the lane's scope ruling (aria is color-blind).
Agent Note scenario list extended in both languages; pairing re-recorded.
One two-turn seed (turn 1: bash + two parallel reads in a single assistant
message; turn 2: a markdown-heavy reply) rendered cold through the
seeded-history pattern — zero model calls — serving four surfaces:
- sidebar search: client-side title filter; asserted only after the durable
title lands with the attach baseline (a cold SessionSummary carries no
title — search matches the displayTitle the user sees). Negative query
empties the tree, positive narrows to the match + its force-expanded
group, clear restores.
- Trajectory tab: turn sections, the step group's tool mix ('bash read×2'),
and a view-area aria golden.
- Waterfall tab: span stats header + one lane per span. The P-I fold counts
a turn-0 prologue span (only assistant/steering nodes carry a turn
number) — pinned as-is; real spans are P-III per the view's ledger.
- details column: the bash toolview row routes click to openDetails;
open/closed is asserted on the frame's data-details-collapsed attribute
because close collapses the grid column to width 0 without unmounting
the subtree (hidden, not absent, is the contract).
Agent Note scenario list extended in both languages; pairing re-recorded.
The tasks/ family now matches the capability-seam shape: @deepseek-ai/dsh-tasks
keeps the abstract TaskService (ctx.tasks contract, vocabulary types, snapshot
invariant companion) and the new @deepseek-ai/dsh-tasks-local carries the
process-local registry (LocalTaskService: in-memory store, settlement,
owner-cleanup effects, teardown, TASK_WAIT_TIMEOUT). Compositions and test
harnesses now load dsh-tasks-local; producers, TaskKindMap merges, and
dsh-tool-tasks keep importing the seam only.
Producer misconfiguration diagnostics name dsh-tasks-local because loading the
implementation is the fix. The registry behavior suite moves to tasks-local;
the seam keeps a stub-subclass registration test and the probe-based invariant
suite.
The client indexes tool/code-dispatch events into
ConversationSnapshot.codeDispatches (parent callId -> ToolResultNode-shaped
sub-calls; live mux and history replay build the identical index). ChatView
renders each run_code parent as the new code variant (description summary,
program as the expanded monospace body) with its sub-dispatches as
always-visible indented rows — every sub-row dispatches through the SAME
keyed conversation.chat.toolview hole with the same GenericToolCard
fallback, so custom registrations (bash sample) take over sub-rows exactly
as top-level rows. The details panel resolves sub-callIds to full logged
args and complete output through the native path.
Evidence: fixture turn 64 + built-bundle jsdom snapshot, real-machinery
jsdom suites (nesting, error state, details, running parent, reference
stability), and a recorded code-mode browser e2e round (keyless replay +
aria golden). Scaffold gains a toolsMode patch knob.
Five browser e2e scenarios over the existing keyless lane, one recorded
base fixture per spec family:
- live-interactions: one tool-free recorded turn + per-run override
sidecars authored in the spec (content single-sourced from the fixture
via deriveReplayScript, minted into a spec-owned temp dir). Cancel uses
a hang patch with a readyFile marker — the marker proves the stream is
parked mid-turn before the Stop click, so mid-stream cancellation is
deterministic by construction (turn/end 'aborted', composer re-enabled).
AUTH pins the non-retryable path: turn/end 'error', zero llm/retry
events, composer recovers; FIXME(web-error-surface) marks the found
product gap (no error copy renders — the client consumes no agent/error
frames and a pre-chunk failure freezes no partial). SERVER retry appends
the fixture's own success after an injected throw and proves llm-retry
end-to-end in the browser via the durable llm/retry record.
- question-composer: the shipped ask_user_question takeover blocks the
turn mid-step on the real userInteraction seam; the test answers through
the composer (the one sanctioned model-content-reactive drive step: the
turn cannot complete without it) and the tool result carries the answer.
Adds the composer waiting-state aria golden.
- steering: steers mid-turn while the composer blocks the step (the
deterministic mid-turn window). The steer rides the real wire
(session.prompt mode:'steer' POSTed from the page; the locked composer
has no steering gesture yet — TODO(web-steer-composer)); downstream is
all product: gateway -> Agent.steer -> step-boundary drain -> durable
steering/message -> SSE -> badged interjection bubble. Record mode
rejects a fixture whose live reply ignored the steer.
Scaffold gains the replayOverride passthrough; specs register in both
tsconfig planes (client exclude, host include).
Integrate the Commander adapter with master's headless rework (dsh -p now boots
through AppCLIEntry — the same cordis.yml composition as dsh web, web-observable
while it runs — via toFetchHandler(ctx.apiProxy)).
- headless.ts: keep master's AppCLIEntry-based body but take the adapter's
pre-parsed `task` (drop the re-added parseArgs). Old startHost path and the
now-deleted packages/host/runtime dependency are gone.
- remove the stale packages/host/runtime dir left on disk by master's deletion
(mirrors the earlier packages/ui/acp cleanup).
Boots a test-only cordis.yml through the real Loader and asserts the route
service's behavior surface: exact/longest-prefix matching, tapIndex
transform order and unsubscription, traversal 403, non-GET 405, SPA-200
fallback, malformed-request 400 without process exit, duplicate-pattern
throw, dispose closing held connections with register/disposer symmetry,
and a listen-failure fail-loud case (EADDRINUSE -> FAILED fiber + late
rejection). Replaces the retired factory-era specs.
Integrate the Commander argument adapter and dsh-front-door work with master's
config-tree `dsh web` (#601: AppCLIEntry + apps/cli/cordis.yml) and the
packages/ui/acp → packages/acp/acp relocation.
- web.ts: keep master's AppCLIEntry-based boot, but take the adapter's parsed
(host, port, dev) instead of an internal parseArgs. The adapter's host/port
defaults (127.0.0.1/3080) match cordis.yml, so always passing them is
behavior-equivalent to master's "undefined keeps the yml default".
- apps/cli/package.json: master's expanded config-tree dep set + commander.
- retire-readline Agent Note: point the TUI refusal proof at
apps/cli/tests/built-bin.e2e.ts (both languages), re-record the pair.
- READMEs reconciled (demo-bin removal + master's ACP/channel rewording).
