Review corrections on the observation record:
- `pumpJobOutput` subscribes to `done` once and keeps one pending timer;
racing the same pending promise every poll round retained a reaction
per round for the life of the job.
- The `ctx.jobOutput` effect disposer is async and awaits every open
carrier's `dispose()`, so the fiber reports unloaded only once the old
iterators are quiescent.
- `SessionJob.record: true` replaces `outputTotal`: `append` never commits
a roster change, so the mirrored count was stale while output flowed;
the live offsets ride the observation stream's `opened` anchor.
- The record is documented as a best-effort live preview whose
cross-stream reordering is bounded by the poll interval.
- The web e2e scenarios hold their background job on a test-owned barrier
file instead of a wall-clock sleep, and each is one test rather than a
chain sharing a job id.
`session.killJob` becomes `job.kill` on `dsh-api-job-controller`, beside
`job.observe`, so the Session Controller carries only session control and
the roster while every per-job Remote lives on the job namespace. The
client `ctx.jobOutput` gains `kill(sessionId, jobId)`; `dsh-client-ui-jobs`
routes its stop control through it and no longer requires `sessions`.
Unknown or foreign jobs reject with `job/not-found`; the controller
requires `ctx.jobs` to load, so `jobs-unavailable` disappears. The two
subagent ownership-fence helpers are classified duplicate-install-safe
Host exports of the Session Controller for the cross-controller import.
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.
The persistence seam is now create/open/stat/list returning per-session
SessionHandles (read/append/flush/close); every log read and write flows
through the owning handle. The seam package exports only the service and
handle contracts, consumer-visible errors, and pure durable-data
validation helpers; each backend owns its complete storage runtime, and
the shared contract suites pin equivalent observable behavior. The
backend routes published sessions' live events by id into the active
write handle; agent-loop only acquires, seeds, and closes the handle.
Resume appends interruptedTurnClosers through its write handle;
session-query owns the revision-keyed cold cache. Legacy-only surfaces
are removed in the same swap: locate/readRaw/supportsRawArtifacts, the
legacy event-shape read migration, zstd torn-frame salvage,
DSH_SESSION_JSONL, and hook transcript_path population; a torn final
zstd frame is discarded whole; the session-list cold blank probe returns
on stat metadata (eventCount derived from the last physical row,
sizeBytes). The WebUI ZIP export serializes the logical log from a read
handle, so both backends export identically.
Refs #3245
Carries the session seq-brand master sync forward; unions the seq/offset
imports with this branch's jobs augmentation in commands.ts and
regenerates the catalogs and zh ports over the merged source.
Absorbs the session seq-brand refactor and the turn-rail preview layer;
regenerates the catalogs and graph docs from the merged source and
re-ports the zh config/event rows this branch owns.
Covers the woken-wait fast path (a wake landing while the generator is
suspended on a yield), the opened frame's live-detail arm, and the
sessionId-less caller resolution over an unowned job.
Carries the master sync forward (invariant-companion cleanup, alpha.3 bump);
regenerates the client api catalog so ISession lists both killJob and the new
loadThrough, and refreshes the new ptc-python-turn scenario's system-prompt
pin for this branch's bash timeout-promotion schema text.
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.
Observation (re)opens run on caller stacks — a React expand click, a
carrier retry — whose dynamic context has not declared remote.session, so
the ClientJobOutput wiring resolves the namespace to a concrete value while
the plugin's own context is current, exactly as the activity client did.
Caught by the live-job-stream web e2e, whose goldens (with the
background-job-list pair) now carry the ui-jobs list name; the client-apply
spec gains a jobOutput wiring smoke.
The regenerated session namespace requires the new stream; the fake serves
a never-yielding generator, and job-output.client.spec exercises the real
consumer.
SessionJob rows carry outputTotal exactly for record-declaring jobs, and a
new session.observeJob stream serves one job's retained record from an
absolute offset (anchor, coalesced output frames, terminal status) with the
fenced read resolved from the request's session — the same authorization
shape as the jobs roster. The client half gains ctx.jobOutput: the
reference-counted per-job observation service and its accumulated view
model, ported from the activity controller this replaces.
loadThrough now assigns its low-water target only when it owns the loop
(retargeting stays inside the running-jump branch): a call refused while
a plain load-earlier pull holds the pager no longer leaves jumpTargetSeq
behind to drag a later jump all the way to the head. The loop also
carries the doOpen stale-pass guard so a mid-flight resync stops it
instead of paging the new stream generation toward the old target.
Session.loadThrough(seq) loops the existing prepend pager (200-message
pages) until the window covers the target seq, with a shared low-water
retarget for repeated calls, a no-progress guard against empty pages
still claiming history, and loadOlder's fail-soft error posture. Busy
state rides the existing loadingOlder snapshot bit.
- protocol: isDSHRemoteGatewayError -> isDSHRemoteError (the class is
protocol-wide, not Gateway-specific); remoteErrorOf drops its
instanceof Error precondition and tests the marker plus a string code
structurally, so a marked failure from another realm no longer reads
as a local defect.
- session-controller: the live-follow packed-record protocol violation
now throws a marked RemoteError('gateway/internal'), landing the
session in openState=error instead of an unhandled rejection;
pinned at the transport and session levels.
- util-time: correct the invariant companion's @module name.
- regenerate the tool-cordis catalog for the marker rename.
- api/gateway: mark terminal Remote-stream escapes (carrier retry
exhaustion and pre-acceptance end classification) as
RemoteError('gateway/internal') at the two escape points; marked
failures pass through verbatim. The carrier class stays the
retry-internal signal for carrierFailed and the ended(true) retry
trigger. Regression coverage lands on the session and workspace
stream consumers.
- client/ui-tool, client/ui-workspace: read $host.home through a hooks
observable subscribed to connection/reset; the slot renderer memoizes
inject results per entry, so the previous plain-value injection froze
home at the first render.
- client/ui-settings-models: components no longer receive ctx; apply
binds the credential and settings Remote operations into callbacks,
and the settings/conflict code judgment stays in the apply world.
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.
The master merge slimmed the client Session constructor to (id, remote,
options); the killJob specs from this branch still passed the FakeApiClient
as a second argument and stopped compiling.
