History, State and Web become ordinary classes sharing the Session scope.
Subscribe-before-read removes the tail repair, events and page expose the
cursor-bearing history read, observeEvent keeps a pure event subscription,
and follow stays passive unless activate is requested.
Add @deepseek-ai/dsh-agent-controller, composed in the base bundle, as the
entry through which a sender delivers a message from outside an Agent into
its inbox. deliver() runs the sender's content preparation in the Agent's
delivery order, asks the agent-controller/admission waterfall for a
decision, rechecks cancellation and registration, and appends the message
with followup() or steer(). dsh-agent and agent-loop are unchanged.
The Web session/prompt Remote delivers through it: the image model check,
upload receipt resolution, and attachment storage run as prepare, the
receipt binding runs as beforeInsert, and refusals map to
session/prompt-rejected. The Web client keeps its existing echo.
This replaces the Host half of deepseek-harness/deepseek-harness#6178,
whose admission stage lived in dsh-agent.
Add @deepseek-ai/dsh-agent-model. It provides ctx.agentModel
(resolveForNextStep, select, applyConfiguredRoute) and owns the
modelSelection projection, which the Agent registry no longer registers.
dsh-agent-loop now injects agentModel; the base and SDK-minimal bundles
and the Python SDK runtime include it.
The provider keeps the projection registered until consumers that are
still unloading finish their cleanup. The model-switch notice becomes an
opt-in per-Agent plugin at @deepseek-ai/dsh-agent-model/notice, and
agent/request now also rejects reasoning-effort changes after step
preparation.
Mount the provider in every composition that loads dsh-agent-loop, and
update consumers, the switch-notice snapshot driver, docs, and the
upgrade guide.
* feat(workspace): stop a Session's running work before archiving it
Archiving was a pure visibility write, so a Session archived mid-turn kept
running out of sight. The Workspace registry now owns archive admission
through two Host events: `workspace/session-activity` reports what still
runs and refuses the plain archive as `workspace/session-active`;
`workspace/session-stop`, requested with `stopActivity`, stops that work the
way the user's own stop actions do before the archive write. The API Session
Controller reports and stops turns, subagent descendants, and owned jobs and
rejects any model step for an archived Session; the Schedule plugin reports
and deletes active reminders. The sidebar turns the refusal into a
stop-and-archive confirmation listing the Host's answer.
* test(workspace): pin the widened archive signature and prove child liveness by heartbeat
The Client inspect catalog spec pins archiveSession's new options
parameter, and the archive e2e reads the Bash child's liveness from a
heartbeat file instead of a pid: the Linux sandbox runs the tool in its own
PID namespace, so the pid it reports is not comparable from the test.
* test(workspace): cover the archive-admission providers and dialog to the per-file gate
Drop the provider's unused disposer and the dialog's unreachable confirm
guard, read reminders without a catch that no composition can reach, and
add the cases the coverage lane found missing: a stop without a jobs
registry, a looping lineage, a descendant whose projections reject, the
dialog's Escape guard and non-Error reason, and a family merged by another
provider.
* fix(workspace): write the archive before stopping, gate subagent lineage, and delete reminders under the schedule barriers
Review round on #4765. The registry now writes the archive set before it
dispatches `workspace/session-stop`, so the durable set already gates
every wake the stops induce; the controller's `agent/pre-step` gate also
blocks subagent descendants of an archived Session and contains each
cancel or kill on its own. The Schedule plugin's stop listener runs as a
management delete in the agent's transaction queue between the same two
persistence barriers the `schedule_delete` tool uses. The confirm dialog
selects singular or plural English lines and keys list rows by index.
Docs: archive-admission section with type-equiv blocks on the workspace
subsystem page, write-first order and residual windows in the READMEs
and the Agent Note, and the missing zh reminders sentence.
* test(web): scope the question composer's New Session wait to the Sessions tree
The wide sidebar's New Session button carries the same visible label as
a fresh session row, so the unscoped `getByText` either settled on the
button before the row existed or hit a strict-mode violation once the
row rendered first, which is how the snapshots lane failed on
ece68c2ab5. Waiting inside the Sessions tree names the row alone.
* fix(schedule): answer archive admission from the owned runtime's fold, not the projection registry
The `sessionProjections.snapshot` API is the Client projection view and
is not a Host read path (review on #4765). `ScheduleRuntime.activeRecords()`
folds the live log the way every drive does, and the archive-admission
listeners ask the owned runtime for that fold: a session without a live
agent or without an owned runtime has nothing armed to fire, so it reports
nothing and has nothing to stop. Covers the runtime-less agent, a fold that
turns unreadable at the persistence barrier, and the stopping/faulted
runtime answering nothing.
* refactor(subagent): report and stop subagent descendants from the Subagent runtime
The `subagent` family of archive admission moves out of the API Session
Controller into `dsh-subagent`, which records the lineage at delegation
and owns the descriptor (review on #4765): `SubagentRuntime` answers
`workspace/session-activity` with the running descendants, labelled from
each child's descriptor through a live Session observation, and
`workspace/session-stop` by cancelling each of them with the parent
cause. The controller keeps turns, owned jobs, and the lineage step gate,
and composes its provider through `ctx.plugin(SessionActivityProvider)`
with declared injections instead of a bare installer call. `dsh-workspace`
becomes an optional type-only peer of `dsh-subagent`.
* refactor(jobs): answer archive admission for owned jobs from the job registry seam
The `job` family moves out of the API Session Controller into `dsh-jobs`
(review on #4765): the seam's constructor installs the
`workspace/session-activity` and `workspace/session-stop` listeners for
every implementation through the abstract `list` and `kill` alone, so the
controller no longer knows the jobs vocabulary and keeps only the turn
family and the archived-lineage step gate. `dsh-workspace` becomes an
optional type-only peer of `dsh-jobs`.
* refactor(workspace): leave SessionActivityKindMap empty and let each provider merge its family
The workspace package no longer names any activity family (review on
#4765): `SessionActivityKindMap` is empty, and each provider merges its own
key from a module both its faces import — `turn` in the API Session
Controller's types, `job` in the job registry seam's view, `subagent` in
the Subagent runtime's control types, `schedule` in the Schedule plugin's
types. The confirm dialog imports those modules for its cases and keeps
the generic line for any other key; the registry and controller suites
merge test-owned families instead of borrowing the providers'.
* refactor(agent): report and stop the running turn from the Agent registry
The `turn` family moves out of the API Session Controller into `dsh-agent`
(review on #4765): the registry's constructor installs the
`workspace/session-activity` and `workspace/session-stop` listeners for
every Agent it publishes, answering with its own lookup and cancelling the
turn with the user cause, and merges the `turn` key from its client-safe
types. The controller keeps only the archived-lineage step gate, renamed
`ArchivedSessionGate`. `dsh-workspace` becomes an optional type-only peer
of `dsh-agent`; the workspace package depends on none of the providers,
so the edge stays acyclic.
Since #3127 a foreground Bash command is a registered job from its start,
so the archive dialog lists it beside the turn; the e2e and its ARIA golden
expect that row, and the capture keeps the running job by design.
* feat(preset): declare Agent compositions in profile YAML
* fix(preset): share scope binding cleanup and refresh module graph
* fix(preset): use host syntax colors in the YAML editor
* fix(preset): write new profile declarations as block YAML
* fix(preset): align eager activation with browser and worker surfaces
* fix(ui-agent-preset): retain the existing preset card layout
* fix(preset): keep rows waiting for a Host service mounted and re-audit after settlement
A preset row whose Host provider was still activating at declaration time
was reported as waiting for a missing service, and the registry recorded the
definition as broken for the rest of the process. Split the mount audit into
failed and pending rows: failures and root-realm leaks still reject the
mount, while pending rows stay mounted and every read and binding re-audits
them after the Host Loader tree settles.
Remove the accidental self-dependency of @deepseek-ai/dsh-web-app and its
lockfile self-link. Archive the copy-only preset authoring note, which the
declarative-preset note fully supersedes, and update the ralph note's
restore recipe to the profile-patch mechanism.
* chore(lint): re-key and prune the unknown-cast baseline after the master merge
* refactor(web-app): ship each Agent preset as its own bundle patch file
`dsh.bundle.patch` accepts an ordered file list, so the four shipped preset
declarations move out of the 1000-line web patch into
`presets/<id>.patch.yml`, one insert per file, applied after the host patch.
The host patch keeps the preset registry row. Gates and test scaffolds that
read the web layer resolve every patch file through `bundlePatchPaths`
instead of one hardcoded path.
* refactor(preset): drop the save notice injected into live Agents
The notice duplicated the save result the Web editor already shows, and
after the producer-owned message sources it would have needed its own
persisted source kind. Saving now only persists and reports the activation
diagnostic; the persistence catalog is unchanged from master.
* docs: regenerate the module graph after dropping the registry's llm dependency
* test(ui-agent-preset): cover the guide dialog's keyboard handling on the declarative section
* fix(preset): address the remaining review comments
Apply the lowercase id rule only when creating a declaration, so presets
declared with other ids stay editable. Export `isBuiltInPreset` from the
display fold and key the client card groups on it. Remove the dead `error`
and `retry` locale keys, the JSDoc orphaned by the `trust` removal, the
`trust` fields in the plugin-inventory test fixtures, and the stale
`dsh-agent-presets` package name in comments and READMEs.
* refactor(preset): make the Web preset page view-and-select only
Remove the child-plugin YAML editor, the `agent_preset` tool and the
registry's read/save Remote methods. Presets are declared and changed only by
bundle patches; the settings page keeps the roster, the new-task default and
the mode help, and its question icon explains that and offers to start a
Creator-mode task. The `editing-cordis-compositions` skill and the Creator
persona describe the bundle-based path, and the authored skill-load Session
and Web snapshots are refreshed for it.
* docs(skill): make the composition skill self-sufficient for preset authoring
State where the shipped declarations live, list every declaration field,
inline a complete minimal bundle and an override example, and name the
verification calls, so Creator mode no longer reads DSH package sources to
infer the format. Refresh the authored skill-load Session for the new text.
* test(tools): drop the removed agent_preset tool from the catalog expectation
* feat(subagent): align continuable human inbox controls
* fix: repair rebase documentation and close test persistence
* docs: refresh rebased module dependency graph
Assistant prose that references a workspace-contained local media path
(e.g. ``) now renders through a same-origin
`GET|HEAD /api/file?path=` route instead of inert alt text.
- ui-primitives: MarkdownText gains a settled-only MarkdownPathImages
vocabulary gate (same posture as file mentions); no vocabulary means
byte-identical output.
- ui-chat: AssistantMarkdown supplies a page-stable rewrite vocabulary
for absolute POSIX paths (local-path-media.ts).
- session-controller: SessionMediaReferences plugin contribution mounts
the route on the authenticated connection.fetch channel; per-request
policy = workspace-root containment after realpath, regular file,
allowlisted media extension (images additionally signature-checked),
range/HEAD streaming, private no-store + nosniff, fail-closed statuses.
- Agent Note added (feature/2026-09-07-session-prose-local-media-display).
Closes#3662.
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.
