AgentAdmissionRejected now extends HarnessError with the fixed code
AGENT_ADMISSION_REJECTED. The Session Remote recognizes a refusal by that
code and imports only agent-controller types, so its mapping also holds for
an error from another copy of the module; its literals are typed by the
agent-controller constants, so a changed value fails the build.
Master's async activation makes AgentRegistry inject sessionProjections and
makes createSessionTestRemote async. Install SessionProjectionRegistry in the
agent-controller and prompt-admission harnesses and await the test Remote in
the image admission tests.
Plugins bundle pages and Discover entry pages show the plugin's long
description first, as Markdown with images, in a height-limited region
without its own heading. The document is the file locale meta.detail
names, otherwise the package README, otherwise (market entries only)
the declared repository's README.
The new dsh-plugin-detail library selects documents and reads local
package directories and npm file CDNs without state. plugin-manager
reads installed and offered bundles through readBundleDetail; plugin-market
reads market entries through readEntryDetail, single-file APIs, and a
size-limited partial clone cache serialized across processes. Raw HTML is
omitted, relative links stay text, and relative images load from Host
routes with a sandbox CSP.
session-controller registers its resolver through `ctx.fileUploads`. Inside
that call Cordis returns a new proxy for every function-valued property read
from `this`, so the disposer's identity check never matched and the slot was
never cleared. Any restart of session-controller, such as a profile patch that
changes session-query-sqlite, then failed with "Agent resolver is already
registered" and left every sessionController dependent pending.
Store the resolver in a plain holder object, as the commands receipt resolver
already does, and test registration and disposal through a plugin fiber.
The Agent controller now finishes disposal only after every delivery it
stopped has settled, and a sender that cancels stops waiting at once, also
while its message waits behind a held one; the message keeps its place and
is dropped at its turn.
An image prompt takes the Session's image admission turn when its
preparation starts, in the Agent's delivery order, and keeps it until the
prompt settles. Image and text prompts therefore enter the inbox in arrival
order, and a model selection waits only for the image prompt being
admitted, not for one still queued.
The core page documents the delivery types, and the architecture overview
lists the controller and its admission event.
- Export `ProjectionKeySelection` (the read faces' key selection) and reuse it
from the projection cache instead of restating the union twice. The Cordis
catalog can now resolve the type its generated signatures reference.
- Make `wire.summary` a plain boolean: omitted means `true`, and a key whose
map entry carries the summary mark declares `false` so the runtime key set
and the client view type agree. The type no longer forbids a declaration.
- Describe the mark accurately: it has no runtime representation; `wire.view`
and `viewSchema` are typed with `SessionProjectionViewValue`, which strips it,
so the registration erase only widens the state type.
- Say plainly in the package README, the subsystem page, the client field
comments, and the Agent Note that a list row carries the summary projection
and never the full projection: a connected Session's store may hold more
values, but those are outside the list contract.
- Document the summary vocabulary on the subsystem page with `ts type-equiv`
blocks for the mark, its stripping, the excluded-key test, the summary value
type, and the key selection; split the prose paragraph.
- Revert the behavior-neutral cache-double refactors in three specs, and record
in the Agent Note why no upgrade guide accompanies the wire change and how a
consumer migrates.
`imageLimits` is a boot constant every Session shares: the unit stores no
per-Session state (`stateSchema: z.null()`, `apply: state => state`) and its
view returns `ctx.attachments.imageLimits`. A list row therefore repeated one
host-wide capability fact on every row. It now carries the summary mark like
the three log-derived units, so a summary read skips it while an opened Session
still receives it through `session/follow`, the control baseline, and
`session.projections`.
No other logic changes: the registration, its schema, its constant view, and
the host-side prompt validation keep reading `ctx.attachments` directly.
A Session-list row no longer carries every registered client view: the three
units whose values a list row never renders (`turnOutline`, `sessionStats`,
and `todos`) are excluded, which removes the whole-log turn outline and the
figure and todo payloads from every row. An opened Session is unchanged —
`session/follow`, the `session/control` baseline, and `session.projections`
still serve every projected key.
The exclusion is one type-level mark plus one registration interlock:
`SessionProjectionSummaryExcluded<T>` marks a map entry, and
`ProjectionDefinition.wire` requires `summary: false` exactly on a marked key
and rejects it everywhere else, so the mark and the declaration cannot drift.
A nullable entry keeps `null` outside the wrapper, so `todos` stays
`TodoItem[] | null`. `summaryKeys()` returns the derived set, stable until a
registration or its disposal changes the key table, and the existing
key-taking read faces (`cachedSnapshot`, `viewCheckpoint`) accept that set
directly, so summaries need no separate read face and no per-read key copy.
`packages/api/session-controller/src/list.ts` passes the set to the live and
cold cached faces; `cachedPredecessorTitle` is untouched.
Client types only: `SessionSummary.projectionValues` narrows to
`SessionProjectionSummaryValues`, `SessionProjectionSnapshot.values` keeps
every view value with the mark stripped, and no wire field or client name
changed. The cache, subsystem page, and package README document the summary
rule and the two read faces.
Correct the downlink-write activity contract for compressed frames: a write
that does not complete at once counts, and a frame above the threshold
deflates asynchronously so its completion always counts. The Host compresses
only its own outbound frames; uplink compression remains the peer's choice.
Stabilize the compressed-write liveness test with a 500 ms heartbeat interval
and assert the bounded half: after the downlink stops, missing Pongs still
terminate the socket.
Refs #6476
Restore the `ws` default `maxPayload`: the pre-change mux passed no limit, so
the 1 MiB ceiling was an unrelated breaking change. Remove the exported
constant and the oversize-frame test, and drop the matching docs.
Pin the per-frame compression threshold and the accepted compressed-write
liveness consequence with regression tests, correct the queued-write
documentation, move the Agent Note to `implemented/`, and sync the Remote
duplex stream note with `websocketCompression`.
Refs #6476
Add a `websocketCompression` Gateway config field (`'deflate'` by default,
`'none'` to disable) and negotiate `permessage-deflate` on `/api/remote.mux`.
Frames whose JSON text reaches 1024 characters are compressed in the mux send
path, because `ws` ignores its `threshold` option under the default context
takeover. `maxPayload` is bounded by `max(streamInboxBytes, 1 MiB)` so one
compressed frame cannot inflate past the fixed ceiling.
Fixes#6476
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.
Read configured plugin market indexes on the Host, search them with fuzzy
multilingual matching, and install a chosen version from the Plugins page.
- dsh-plugin-market-index validates format-1 indexes and builds install
arguments; inline icons are capped at 32 KiB.
- The pluginMarket service fetches configured http(s) URLs, parses bodies in
a Worker Thread, caches documents, and pages filtered, ordered results with
installation status and engines.dsh compatibility.
- Discover is an opt-in experimental bundle; the Plugins page gains a
plugins.tab slot and confirmed installs.
- The plugin_market tool lists indexes, plugins, and versions for Creator mode.
- Plugin compatibility reads engines.dsh before DSH peer dependencies.
Folding on the next message reserved the whole closing height as bottom
room and kept scrollTop whenever the input had no transcript echo on this
page: a message from another tab, a queued message delivered after the
previous Turn, or a send from a subagent child in the right Sidebar. A
reader below the fold was left on an empty viewport.
Every batch of closing rows now runs on the viewport's frame-clock driver.
It lands at the tail for this client's own input or a following reader and
otherwise keeps the reader's content still, installing only the room the
landing lacks. Subagent child sends register a local echo and pass its
request id to subagents.prompt, so the child's recorded message retires it.
