Review asked for the observation wire and its client service to leave
session-controller: a job should reach the Host only through its own
Remote namespace, and the session plugin's apply had to materialize
{ $stream, session } for a service that is not session state.
@deepseek-ai/dsh-api-job-controller now owns the Host JobController
(job.observe over ctx.jobs, requiring the agent and job registries) and
the client ClientJobOutput (ctx.jobOutput) over ClientJobOutputModel,
resolving both Remote faces in its own apply. The remotes assembly
mounts the job namespace; ui-jobs injects the new package; the wire
types drop their Session prefix and spell the status union out so the
client face pulls no Host declaration merges into browser programs.
session-controller keeps the jobsBySession roster and loses observe-job,
job-output, and the observe cadence config.
ui-chat's slots and snapshot-builder import CommandNode and friends from
the declaring package: the typert analyzer's cross-package rule trips on
the snapshot re-export as soon as another client face joins the root
Client program (the new controller does), which is why this branch
carried the change before. JobPumpSource documents why it is an offset
snapshot reader rather than a Node.js Readable.
Absorbs the repo-wide no-op invariant companion removal (ui-jobs loses its
placeholder companion, export, and devDep), the 0.1.2-alpha.3 release bump,
and the tool-subagent-report package retirement; regenerates the client slot
catalog for the shifted contract line numbers.
packages/activity/* and packages/api/activity-controller are removed. The
web roster is the session control stream's jobs frames alone; per-job output
observation rides session.observeJob and the client ctx.jobOutput service.
ui-activity returns to its upstream name ui-jobs and renders the single
roster — a row is expandable exactly when its job declared a record
(outputTotal present). Composition rows, dependency-policy exemptions,
tsconfig aliases and references, generated catalogs, and the docs pages
follow; the activity subsystem page is deleted and the jobs page gains the
record contract. The superseding Agent Note records the decision and points
the three prior notes at it.
New turnOutline projection unit serving every started turn's number,
turn/start seq, and bounded first-prompt preview through the
session-projection seam, mounted in the web-app bundle for the chat
turn rail. Entries stay strictly increasing; previews mirror the rail's
loaded-turn preview budget.
The CPython code runtime's complete public contract is experimental, so it
moves to packages/experimental per the experimental-packages rules: npm name
@deepseek-ai/dsh-experimental-code-runtime-python, private: true, no
publishConfig. All references updated (code-runtime READMEs, config-catalog
and module-graph regenerated with zh alignment, tsconfig paths, doc-standard
and workspace-constraints scripts, the fd-3 and settlement Agent Notes, and
the package README links); md-links and translation pairing pass, and the
suite still runs green.
Single RemoteError with a merge-extensible, domain-prefixed code map;
owners throw at the failure point; streams surface marked failures;
clients consume ctx.remote directly with isRemoteFailure as the only
discrimination point and construct no failure instances.
Rename the tool-presentation transport from code-mode to ptc everywhere
that is not written into session logs: the mode config value becomes 'ptc',
the preset directory/id becomes ptc, the demo becomes demo:ptc, the
dispatch waterfall becomes tools/ptc-dispatch-log (types PtcDispatch*), the
prompt rule becomes tools:ptc-only, source/test files become ptc.ts etc.,
and prose says PTC mode / PTC 模式. The session-persistent vocabulary
(durable events tool/code-dispatch*, logged plugin name tools-code-mode,
sub-call id segment :code:) intentionally stays and moves in the stacked
persistence PR, which is blocked until the SESSION_FORMAT_VERSION v0→v1
migration lands with it. run_code, its code parameter, CodeSdkLanguage,
CodeRunFailedError, the dsh-code-runtime family, third-party codex names,
and frozen archived notes keep their names.
A steer or follow-up accepted while a turn is closing is now claimed by a
fresh turn at the driver's clean exit instead of stranding in the inbox;
cancellation and pre-step rejection still park accepted work. Continuable
subagent follow-ups accept image parts: the wire is upload-shaped, the Host
admits and persists each batch before inbox acceptance, and delivery is
refused when the child model declines image input. The queue dock renders
durable image thumbnails instead of an [image] text marker.
Fixes#3186
Keep five non-blank rows stable while the selected blank New Session is provisional, and derive the overflow count from the rows still hidden.
Fixes#2841
Keep recognized code fences syntax-highlighted while assistant text streams. Preserve completed Shiki token lines across chunks, mirror token styles and CRLF handling, and retain plain rendering for unsupported or math-like fences.
Add unit, DOM-parity, and keyless assembled-Web coverage for the streaming-to-settled transition.
Closes#1499
Add the activity capability seam: ctx.activities is a pure observation
plane where long-running work (background bash/pwsh, workflow runs) opens a
handle, appends transient output into a byte-offset ring buffer, and settles
exactly once. Nothing model-visible changes: reads are non-consuming and
lossy-by-design (absolute UTF-8 offsets survive eviction and report gaps),
correlation carries {callId, jobId}, and visibility is owner-fenced like jobs.
The seam is strictly optional. Producers tap it through ctx.get('activities')
and contain every observation failure, so an unregistered or broken registry
never affects the underlying job (proven by broken-registry tests).
Ship the full path in one change:
- @deepseek-ai/dsh-activity: Service Definition, pumpActivityOutput pull
substrate, invariant companion; dsh-activity-local: ring-buffer provider
with retention config and owner cleanup.
- shell: ShellProcess.observed exposes non-consuming stdout/stderr readers;
tool-bash/tool-pwsh mirror background jobs into activities.
- tool-workflow: phase/log/agent lines mirrored as a workflow activity.
- api-activity-controller: Typert Remote control (roster baseline+buckets)
and observe (opened/output/status frames, coalesced and byte-capped)
streams plus the client feed service with reference-counted observation.
- ui-activity: session-header action rendering live output through
TerminalBlock, which now shows output while a command is still running.
Docs: activity subsystem page, architecture row, regenerated catalogs, and
the Agent Note (2026-08-24-activity-observation-seam), all bilingual. A
keyless web e2e replays a real run_in_background stream to ARIA goldens.
Add a startup-only sdk-minimal template whose sole bundle inserts the complete JSON-RPC agent tree over the empty profile root. The roster is an explicit composition allowlist: it contains one DeepSeek adapter, the minimal agent spine, persistent Bash, the string-replace editor, local execution, and JSONL persistence, while dsh-base and Web remain absent.
Reuse the SDK app startup provider so the new profile retains help, stdin EOF, and bounded launcher shutdown semantics. Make that provider render its configured profile name, which keeps both sdk and sdk-minimal help truthful without duplicating process lifecycle code.
Register the package in the CLI closure, TypeScript graph, lockfile, Knip policy, and bilingual bundle references. Exact manifest, row-roster, profile-template, config-dump, and HMR tests make later additions visible instead of relying on a blacklist.
Delete @deepseek-ai/dsh-sdk-python-runtime and its packaged-bin entry now that Python uses the repository's dsh application launcher. Remove the package's project reference, Knip entry, workspace-policy exception, executable allowlist entry, and README-model classification together so no tooling preserves the old exception.
This commit is deliberately mechanical: it removes the obsolete package and gate accommodations without introducing the replacement launch behavior. The following commits add the packaged dsh runtime and Python profile API, keeping the architecture change separate from deletion noise.
Update workspace manifests, the lockfile, Host project references, Knip inputs, package constraints, vendoring rewrites, and Python runtime build/smoke scripts for sdk-app, acp-app, and @deepseek-ai/dsh-sdk-python-runtime. Add the ACP hook packages to the dsh dependency closure so installed profile materialization resolves the same plugins as source workspaces.
Keep Python distribution outputs deliberately unchanged: the wheel modules, executable names, and smoke targets retain their public identities even though their private npm carrier moved. Constraint fixtures pin the new package locations and catch missing application dependencies on every platform.
Introduce @deepseek-ai/dsh-acp-app as the thin application layer for the built-in acp profile. It contributes only the ACP protocol bridge and profile metadata; dsh-base remains the single owner of shared agent composition, providers, persistence, permissions, and tools.
Wire the bundle into CLI resolution, catalogs, workspace configuration, and built-bin coverage. The focused bundle and startup tests prove that base plus acp-app exposes automation sessions while keeping stdout reserved for ACP JSON-RPC.
Introduce @deepseek-ai/dsh-sdk-app as the thin application layer for the built-in sdk profile. The bundle contributes the JSON-RPC server and startup-only profile metadata, while dsh-base continues to own the shared agent, provider, persistence, and tool composition.
Publish ctx.appReady from the launcher only after the Loader tree and launcher-owned setup succeed. The stdio lifetime binding leaves stdin unread until the protocol transport claims it and defers EOF exit 0 until readiness commits, so early protocol frames remain buffered and a racing startup failure remains the nonzero process outcome. Fiber disposal cancels both pending lifecycle listeners.
Register the bundle in the CLI resolver closure, generated configuration catalog, workspace graph, and built-bin smoke. Startup tests prove that base plus sdk-app exposes the SDK server without taking ownership of shared runtime plugins; focused and built-bin regressions cover early input, EOF readiness, and startup-error precedence.
