The descriptor module claimed that no parent exists during cold resume, using that as the reason maxTokens cannot be inherited. Continuable follow-up actually requires and authorizes the exact live direct parent before it loads the descriptor and materializes the child, so the stated lifecycle fact was false.
Keep the real persistence decision explicit: per-activation budgets are not durable descriptor composition. Cold resume reconstructs child options only from the curated durable fields, so it deliberately neither restores the establishing budget nor inherits the live parent current transient budget; the resumed provider and model route defaults apply.
This is a contract-only correction with no runtime change. The exported JSDoc gate remains clean.
The localized catalog exposed one count.total and one count.running string for every cardinality. The English dictionary therefore rendered both the visible trigger and its accessibility label as 1 subagents, and the assembled Web golden had begun preserving that grammar error.
Split both count families into explicit one and other keys, following the existing client locale convention. SubagentCatalogAction selects the pair from the effective descendant count; English uses subagent for one and subagents otherwise, while Chinese keeps its unchanged classifier text under the same key domain.
Add a component regression proving a single running descendant selects both singular keys. Update the real Web E2E locator and keyless assembled aria golden from 1 subagents to 1 subagent. Both ui-subagent test files pass all 28 tests and the package TypeScript project builds cleanly.
ACP waits for every owned Agent disposal and throws one AggregateError when any Session teardown fails. The aggregate message embedded each rejected value with String(failure) because the connection-close logger itself renders only the outer error message. String preserves only an Error name and message, so causes and AggregateError members disappeared from the operational warning.
Render each per-session rejection with the existing errorChain diagnostic helper before joining it into the outer message. The original rejected values remain in AggregateError.errors for programmatic inspection, while the message now carries cause chains and nested aggregate members through the String-based logger.
Exercise a disposal failure containing both AggregateError members and a nested cause, while retaining the existing barrier that proves the second Session finishes disposal before any warning is emitted. All 10 ACP disposal tests pass and the ACP TypeScript project builds cleanly.
refreshSubagents previously treated every overlapping caller as proof that the in-flight response was stale. Selection, menu opening, and reconnect paths can legitimately request the same catalog concurrently without any host mutation, so those reads were coalesced and then followed by an unnecessary second RPC.
Restore ordinary in-flight coalescing at the public refresh boundary. The debounced host/session-added path now owns the membership-specific stale mark: if its timer fires during an older pull, it queues one trailing request; otherwise it starts the refresh directly. Parent removal keeps its separate explicit invalidation and trailing-refresh path.
Add a regression proving two overlapping reads share one Promise and issue one RPC. Rework the membership test to start from a restored selected parent, so only the host membership frame can request the trailing pull instead of the test priming the stale bit with an unrelated duplicate read.
Validated with both focused catalog cases, all 40 SessionManager tests, and the client runtime TypeScript project build.
The earlier removal fix invalidated parentAvailable immediately and queued a trailing subagent.list request, but it still applied the already in-flight success verbatim. That stale success reopened the composer and became the trailing request baseline. If the trailing request failed, its error snapshot preserved parentAvailable:true indefinitely.
Record a false-only parent availability override on the exact in-flight catalog request when the owner removal frame arrives. Successful and failed responses now replay that request-local invalidation before publishing a snapshot, and addressed child Sessions receive the same effective value. The trailing request therefore starts from a false baseline and a later transport or business failure cannot resurrect the removed parent.
Strengthen the regression to assert the catalog and selected child remain read-only immediately after a stale parentAvailable:true success, then fail the trailing pull and assert the error snapshot remains unavailable. The complete SessionManager test file passes all 39 tests, and the client runtime TypeScript project builds cleanly.
Agent setup may await while a mutable contribution registry changes. The previous subagent path validated and committed its provisioning batch inside the setup callback. A revocation queued after that callback returned therefore treated the installation as resident and released it, even though AgentLoop had not published the child yet. AgentLoop could then admit and announce a child whose required capability had already disappeared.
Introduce AgentSetupCommit as the optional synchronous result of create and resume setup. AgentLoop now awaits setup, invokes that commit with no intervening asynchronous boundary, and only then enters the Session and Agent registries. A commit failure follows the existing private-transaction rollback, so neither identity is published and the caller can reuse the id.
Keep continuable-subagent installations provisional until this publication commit. Contribution removal still releases every installation immediately, but now marks an unpublished batch invalid so its commit rejects with ACTIVATION_SETUP_REVOKED. Once the commit succeeds, later removal remains ordinary live revocation.
Cover create and resume ordering, resume commit rejection and identity reuse, and an assembled microtask revocation that leaves only the parent Agent and Session. Update the public JSDoc, architecture flow, package contracts, current Agent Notes, Chinese counterparts, pairing records, and generated Cordis API to describe the new boundary.
Validated with the four focused Agent/subagent test files (91 tests), the isolated assembled regression, targeted TypeScript project builds, generated Cordis API freshness, export JSDoc verification, scoped translation pairing, Markdown wrapping, and Mermaid parsing.
The live fast-path fence and the raced-collision catch duplicated the same
subagent-ownership classification, tripping the duplication gate. Extract
`fencedLiveAgent` so both paths resolve one live identity through the
fence identically.
The client plugin now consumes `ctx.locale` (dictionary registration plus
the slot `t` seat), but the package graph did not know it: no
`dshClient.inject` entry, no peer/devDependency, no tsconfig project
reference. Mirror the ui-conversation convention so the dependency graph,
HMR/preflight metadata, and standalone packaging all recognize the
`@deepseek-ai/dsh-client-locale` seam.
The raced-collision catch mirrored only the subagent-owned half of
ensureSession's `.catch`: a concurrent plain-agent publish winning the
identity still fell through to `internal`, where ensureSession returns
the winner. Mirror in full — classify a subagent-owned winner as
`agent-busy`, return a clean plain-agent winner directly.
The README claimed "acceptance is governed by registry presence" as a
universal statement, but `sendReport` translates a registered parent's
send rejection into the same PARENT_UNAVAILABLE code — registry presence
governs parent *resolution*, while acceptance additionally depends on the
parent's log still admitting appends. Soften both languages to the
precise contract and re-record the pair.
The `host/session-removed` invalidation flipped the owned catalog and
addressed children to `parentAvailable:false`, but a `subagent.list` pull
already in flight was requested before the removal and its ok-response
carries the pre-removal `parentAvailable:true` — the response then
overwrote both the catalog and every addressed child, resurrecting the
writable-editor-against-a-dead-continuation-owner bug the invalidation
closes, with no refresh scheduled to converge afterwards.
Mark the owner stale when a pull is in flight at removal time, so one
trailing refresh runs after the in-flight response settles and the
post-removal host truth lands. Adds a regression test: removal mid-pull,
stale ok response, trailing pull, final state stays unavailable on the
catalog and the addressed child.
The setup validation and commit moved into the callback, so the outer
definite-assignment slot and its type import are no longer needed; declare
the transaction as a callback-local const.
Two pairs needed their confirmed-consistent state refreshed: the
intent-named note's supersession clause (zh link normalized to the shared
`.md` target, since the pairing contract requires identical link targets)
and the report README's acceptance-semantics rewrite (both sides edited).
Re-record both pairs so the translation-pairing gate passes.
Config() applies the schemastery default at runtime, but its return type
keeps the input's optional field, so assert the resolved shape at the
seam — keeping the dead fallback branch gone.
The catalog action (diagnostics, relative times, loading/error/retry,
mode and activity labels, branch toggles, descendant counts, tree aria)
and the read-only composer were hardcoded to Simplified Chinese, so an
English-locale session rendered mixed-language UI. Register a `subagent`
locale namespace (zh source of truth + en dictionary), declare it on both
slot registrations, thread the locale `t` seat through the components, and
mount the locale service in the plugin specs.
The UI spec's zh assertions now run against the real dictionary through a
`t` stub that interpolates `{name}` params exactly like the locale
service.
The tool README claimed a "missing, disposed, or closing parent" fails
the call — but acceptance is governed by the parent's registry presence:
`resolveReportParent` only rejects when the durable parent id is absent
from the registry, so a host-owned parent already in disposal but still
registered still accepts (the pinned host-disposing-parent behavior).
The claim misled callers into treating disposal state as a delivery
signal.
Restate the contract in both languages: absence from the registry is the
only `PARENT_UNAVAILABLE` case, and a failed tool call does not prove
non-delivery — a later `tools/post-execute` veto can fail a call whose
report was already accepted, so the durable child transcript remains the
recovery source.
Adds a regression test pinning acceptance into a host-disposing but
still-registered parent, and rejection after disposal settles.
The descriptor deliberately snapshots a curated composition field set
rather than the merge-extensible `AgentOptions`, and it already names the
per-activation exclusions (`outputSchema`). `maxTokens` is the same class
of property — it budgets one activation, and on cold resume there is no
parent to inherit a limit from, so the resumed activation runs under the
deployment defaults. Spell that out in the module contract so the
fallback is a documented decision instead of a silent surprise for
deployments that set explicit child token limits.
`apply()` resolved the deployment config through schemastery's `Config()`,
which always fills the schema default (`quiet`, pinned by the config test),
so the `= 'quiet'` destructure fallback was dead at runtime on every path —
and as a defaulted parameter it formed a branch no test could ever
exercise against the per-file coverage gate. Remove the fallback and let
the schema be the single home of the default.
The `childCtx.effect()` that routes scope disposal into `releaseChild` was
registered after the install loop's try/catch, so a hypothetical throw
from the registration itself (effect() rejects only on an inactive fiber,
which a live unpublished scope cannot be) would leak the just-installed
batch — neither the setup-rollback catch nor `releaseChild` would release
it. Move the registration inside the try so the existing rollback path
covers it; no observable behavior change.
`materialize` ran `setupTransaction.assertIntact()` only after
`ctx.agents.create()/resume()` resolved — but the factory publishes
`session/created` (and the persistence backend writes the descriptor seed)
inside that call, and `rollbackUnpublished()` only disposes the live
handle; the persistence seam has no delete. A setup contribution revoked
during construction therefore left a durable ghost: `startContinuable()`
rejected with `ACTIVATION_SETUP_REVOKED` and returned no child id, yet
`list_agents` surfaced a persisted `continuable` child whose log carries a
valid descriptor — so a later `send_message` could cold-resume a child the
deployment had explicitly refused to establish.
Move the validation into the creation callback, before the factory can
publish: `assertIntact()` then rejects the create/resume call itself, so
no session is ever persisted for a rejected child. Commit the batch in the
same callback so a later contribution removal releases the installation
instead of invalidating a child already being established (live
revocation, matching the resident semantics).
Pins the rollback regression test to assert that no `session/created` is
ever announced for the rejected child (the parent is created before the
listener registers), in addition to the existing registry assertion.
The connection-close teardown path threw a bare `AggregateError` whose
message counts the failed sessions, and its only production consumer logs
through `String(error)` — which renders the message alone. Compared with
the previous `Promise.all` behavior, every actual disposal failure reason
disappeared from operational logs.
Join the per-session reasons into the aggregate message, matching the
subagent seam's own aggregate disposal messages, and pin the reason in
the dispose spec's warning assertion.
The commands entry's inline comment described the old routing shape
("clients only send a sessionId for a published session") without the
ownership fence that agentFor now applies on every path — the fence's
contract home is the api/commands.ts module JSDoc, so trim the duplicate
and point at the routing shape only, keeping one home per fact.
Explicit-id adoption of a cold session-backed subagent under a *different*
cwd answered `session-conflict` because the cwd check ran before the
persistence inspection classified the identity. The api/commands.ts
contract states explicit-id `session.create` adoption rejects
session-backed subagents with `agent-busy` — ownership is an identity
property, so it must win regardless of the requested workspace.
Reorder the stored-session branch to inspect and classify ownership
first, then enforce the cwd match, making the response match the
documented contract.
When a generic `agentFor` cold resume loses the identity to a parent's
concurrent `enter()` — the collision rejection arrives from
`ctx.agents.resume` publication after the pre-resume re-check — the error
fell through to the `internal` mapping. Clients retrying then see a
transient-looking internal failure instead of the stable ownership error
that `ensureSession`'s `.catch` already produces for the exact same
published-winner case.
Mirror that re-classification in `agentFor`'s resume error path: after the
typed errors, re-check the registry and attached store and answer
`agent-busy` when the raced winner is subagent-owned. Adds a regression
test whose resume mock publishes the subagent winner before throwing the
ID-collision error.
`agentFor` fenced subagent ownership through the attached session store
(`ctx.sessions.get`) and only then returned a live registered agent. A
registered agent whose session is ever absent from the attached store —
an invariant nothing in this package guarantees — would therefore be
handed out through generic Host routing unfenced, bypassing subagent
delivery entirely.
Fence `live.session` directly whenever a live agent exists, and keep the
attached-store check only for the not-live durable classification.
`ensureSession`'s race `.catch` already fences `live.session`; this makes
the fast path the same check instead of an asymmetric weaker one.
`hasSubagentDescriptor` sliced the whole own-suffix events array on every
Agent-bound RPC — including each `session.prompt` and `sessions.models`
call on long transcripts — and `ensureSession` rescans the same suffix
after creation. Replace the slice-then-some with an indexed loop from the
seed boundary, so the classification is a plain O(suffix) read with no
allocation.
A removed session can no longer be the delivery owner of its continuable
children, but the `host/session-removed` handler only reconciled the
removed row's own activity. `parentAvailable` was updated exclusively from
`refreshSubagents` success, and removal schedules no catalog refresh — so
after the parent's Activation detaches, an addressed child kept a writable
editor against a dead continuation owner until an unrelated refresh (or
forever, for a closed menu).
Flip `parentAvailable` to false on the owned catalog and push
`handleSubagentParentAvailable(false)` to every addressed child Session at
removal time, matching the refresh path's notification. New Session
instances already read `parentAvailable` from the catalog, so they inherit
the invalidated state.
Adds a regression test: removing the catalog's owning parent flips the
snapshot's `parentAvailable` and notifies the addressed child instance.
`refreshSubagents` single-flights per catalog owner: a request arriving
while a pull is in flight returns the in-flight promise and is silently
coalesced into it. The in-flight response was requested before the
triggering change, so it can never contain that change — a debounced
membership refresh (50ms after `host/session-added`) firing during a slow
pull therefore lost the new child, and the catalog stayed stale until an
unrelated trigger (reselection, menu reopen, reconnect).
Mark the owner stale on coalescing and re-arm one trailing pull in the
settlement `finally`, so every membership change observed during a pull is
carried by a follow-up refresh exactly once. Bounded: the trailing pull
only runs when a refresh request was actually coalesced, and a new
coalescing during the trailing pull re-marks the same set.
Adds a fake-timer regression test: a `host/session-added` debounce firing
mid-pull yields exactly two `subagent.list` calls and the catalog
eventually contains the new child.
