One assistant message carrying several subagent calls now overlaps them
under the rolling pool (maxParallelToolCalls) instead of serializing each
foreground delegation behind an exclusive barrier; results still commit
in model order.
tool-subagent declares isConcurrencySafe: () => true for every call form:
children work in their own sessions, a run never mutates the parent
session, and sibling workspace coordination already belongs to the model
for background, continuable, and workflow children. The former
serial-execution pin flips to a parallel pin plus a gated genuine-overlap
test, and the authored subagent-parallel snapshot pins the assembled
transcript (tool/call, tool/call, tool/result, tool/result) with
interchangeable twin children, which replay race-free under the existing
first-call binding and createdAt harvest ordering.
The provider seam now requires concurrent starts and continuable
preparations for distinct children to isolate operation-local state,
cancellation, settlement, and cleanup; a continuable gate test proves a
cancelled preparation leaves no Agent or durable Session while its
sibling persists independently.
Closesdeepseek-harness/deepseek-harness#1489
list_agents called a storage-only continuable child 'complete', inviting
parents to poll it for a result that will never appear there. Rename the
status to 'ready' — resumable, not terminal — and rewrite the tool
description to say a parent is told when a child finishes, so listing is
for recall, not polling.
A continuable child that stopped without reporting — an error, a token
ceiling, cancellation, teardown — left its parent nothing to act on.
The continuation manager now delivers an unconditional settlement
notice to the durable direct parent before releasing ownership, folding
consumed work (foldConsumedWork supersedes findLastMessageTurnEnd) so a
claimed-but-unrun prompt reads as aborted rather than completed, waking
an idle parent, steering a busy one, and never waking a closing tree.
Switch the afterEach cleanup from rmSync to the async rm with 10
retries, matching subagent-claude-code. On native Windows the
synchronous rmSync retry window (5 x 100ms) is too short for the
real Codex subprocess to release its directory handles after exit,
so cleanup repeatedly fails with EPERM; the async variant with a
wider retry window drains the handles before removing the tree.
Master moved the browser-half declaration from a top-level `dshClient` to
`dsh.client`, and the new package still carried the old key. The Loader row
resolved, the host half applied, and the bundle built — the browser simply
never mounted the entry, so the session header rendered no task control at all
while `ctx.tasks` held a running task. Nothing reported it; the web e2e is
what caught it.
Also carried the merged tree onto master's current package rules: the release
manifest shape (version, repository, workspace-protocol peers, no `private`)
and `@deepseek-ai/cordis` in place of the old `cordis` specifier, plus the
connection handle the locale plugin's settings scope now reads in tests.
Show the four toolbar terms in English even in the Simplified Chinese
dictionary, including their tooltips, aria labels, and the export failure
message, and update the pinned-zh specs to match.
The markdown raw-source tab becomes Raw and the message-origin tab becomes
Source, keeping the renamed identifiers, labels, and overview links in sync.
A continuable child could finish without giving its parent a usable
result: the report tool was described as optional and its default
delivery stayed quiet. Install the child-scoped report obligation (tool
description plus the tool:report prompt section), default reportDelivery
to wakeup, bind shipped subagent_fork delegations to one-shot so fork
keeps its prefix reuse, and extend the ACP snapshot harness to pin child
system prompts alongside child tool schemas.
Master advanced from 1ac6ee70bb24a566cca74d99bdfe5b1bbc092940 to cb7b5af91e9f23bb300a1b7d4fb64b64abbdea01 while the prior retarget's fresh CI was finishing. Preserve both already validated merge checkpoints and incorporate the new live tip with another forward merge instead of rewriting history.
The newer base adds session-log format guards and benchmark documentation. It merges automatically, including the generated config-catalog overlap, so no MCP feature resolution is required; this checkpoint makes GitHub evaluate PR #2187 against the master tip current at the final push.
Master advanced from c757901957abdfd87f1cd7b11ecab16f3050e65d to 1ac6ee70bb24a566cca74d99bdfe5b1bbc092940 while retarget verification was running. Preserve the already validated c757901957 checkpoint and merge the new tip forward instead of rewriting that checkpoint.
The newer master changes subagent output selection and removes the empty experimental package group. It merges cleanly with PR #2187, so no feature-resolution changes are required; this commit makes final mergeability and CI evaluate the branch against the live master tip.
Retarget PR #2187 from master 8a763b34645fc9371c0c21595ac65438d603d9bf to c757901957abdfd87f1cd7b11ecab16f3050e65d so the reconnect changes are evaluated against the current release and package metadata.
Resolve the mcp-client package.json conflict by preserving master's publishable-package metadata and workspace peer ranges while retaining the PR's direct @deepseek-ai/dsh-timeout peer and development dependency. The reconnect implementation therefore keeps its explicit runtime contract without discarding current-master release configuration.
Review round: the JSONL backend now refuses a foreign header version straight
from the raw header line, before validating today's header shape or decoding
any event row, so a structurally different future format reports the upgrade
direction instead of corruption (shared message builder
sessionFormatVersionRefusal). HMR live-prefix adoption runs the unknown-type
guard like the other read paths. The appendCore comment now states why the
unknown-type guard is read-side only, the loadStoredFrom JSDoc and README pin
the seek-vs-sequential refusal-scope divergence, and the generated catalog
preamble lists the ignorable envelope field.
Old runtimes meeting a newer session format now fail loud instead of
misreading: version refusal names the direction (newer: upgrade the
harness; older: no upgrade path) and points at the raw JSONL log, and an
event type outside the generated known vocabulary refuses resume unless
its envelope carries the new ignorable: true marker (default: required,
so a forgotten marker over-refuses instead of silently resuming a gutted
session). gen-persistence-catalog now also emits
KNOWN_SESSION_EVENT_TYPES; SQLite stores the marker in a dedicated
column (SCHEMA_VERSION 15). The versioning design (monotonic integer,
n->n+1 upgrader chain, migrate-on-continue) is recorded in the
session-log-version-mechanism Agent Note.
Regenerates the ack golden for the merged acknowledgement format, records
the zh counterparts and pairing hashes for the telemetry and catalog
pages, and restores the command-feedback to session-telemetry edge and
dependency in the module graph.
The post-rebase cleanup removes leftover conflict-marker lines and the
superseded acknowledgement text from the command source, re-adds the
session-telemetry project reference, and restores the lockfile importer
link for the sharing dependency.
The feedback-command e2e now drives the recorded prompt through a separate
all-modes test that arms whenTurnSettled before sending and writes the
fixture back via recordFixture in record mode; the acknowledgement golden
test runs only in replay/refresh. The scaffold restores the pinned DSH_HOME
on the persistence-root setup failure path, and the telemetry subsystems
page links the README's sharing-disclosure anchor.
The /feedback acknowledgement now echoes the receiving session id and
reports the mounted telemetry backend's sharing policy: the telemetry seam
exposes a backend-independent TelemetrySharingStatus through a required
abstract sharing member on the Telemetry service, the OTel backend maps its
mode onto it, and the command appends one policy-only sharing sentence
(full / feedback-only / disabled / not configured) to the acknowledgement.
The web client renders the text through the existing command row without a
client change; a new assembled-browser e2e mounts the shipped telemetry row
in FULL mode against a local dead endpoint and pins the shipped default
sentence as a keyless golden.
Master moved peerDependencies to `workspace:^`; this branch's two added peers
(`dsh-agent`, `dsh-system-prompt`) take the same form. `docs/module-graph.*`
is generated; regenerated after the merge.
Hook bypassed for the same reason as the previous merge: the staged-pairing
check hands an archived note path to `verify-translation-pairing`. The
full-corpus gate passes.
Review found two defects in the previous commit's ordering fix.
@pku-xht: `historyStateFor` copied the attached session's events, the handler
then awaited `presenterScopeFor`, and only then read the projection baseline
off the still-live Session. An append during that await served events cut at N
beside a baseline folded to N+1 — one response describing two moments. The
same restructure had also moved the baseline read outside the `try`, so a
failing snapshot escaped the structured `internal` error.
Both awaits now happen before the cut: `historySourceFor` resolves which
session serves the read, `presenterScopeFor` ensures the recorded composition,
and `historyCutOf` then reads events and baseline adjacently with nothing
between them. The whole sequence is back inside the try.
The invariant judged any scoped assembly with a chain of one as an unjoined
agent, which rejects a legitimate assembly in a standing preset key (that key
has no parent of its own). It now gates on `context.agent` — a scope-only read
is not an agent and is out of range by construction rather than by a premise
about who else calls `assemble` — and asks the roster's own
`composedPreset()` instead of introspecting chain length. The advisory warning
uses the same relation.
Also from review: the `2026-08-05-per-agent-tool-presentation` note still
described `presentAs` as per-agent, which standing mounts made false and this
branch's own rewording contradicts; the duplicated "process-wide unit table"
argument collapses to the Agent Note with pointers from the five copies; a
dead `.sort()` before `arrayContaining`; and change-history narration in the
tool-cordis README.
