Pure mechanical rename now that the package's internals are the
worker-thread engine: directory, package name, spec/e2e filenames,
module tags and logger prefixes, tsconfig/knip/run-gates/AGENTS.md
references, example cordis.yml plugin ids, doc links; catalogs
regenerated and the lockfile refreshed.
The outer ring catches up with the engine swap (the package's own
README/JSDoc rode the port commit):
- Seam module doc and README name the worker-thread engine as THE
implementation, with isolated-vm/separate-process sandboxing as the
deferred hardening; the seam service doc states the holder-owned-runs
contract (engine-fiber disposal deliberately leaves live runs to
their holders).
- Seam contract precision: agentsStarted documents the termination-path
degradation to the host-observed count; the events section scopes the
agent-start/agent-end pair to calls that STARTED a child run;
WorkflowRun wording drops the vm-era abandonment language.
- The dynamic-workflows RFC is rewritten in place to the shipped
mechanism (implemented-RFC rule): why worker threads, the thread's
concrete buys, the in-process node:vm first cut recorded under
alternatives considered; the tool section describes the usage policy
as the tool's own prompt section.
- gen-doc-graphs: six workflow/* DYNAMIC_EVENT_DISPATCHERS entries (the
catalog no longer claims nothing dispatches them) and the seam-note
wording; core-data-structures gains its workflow.md index row;
packages/README + AGENTS.md layout line + example cordis.yml comments
say worker-thread; catalogs regenerated.
In-place port of dsh-workflow-vm from the in-process node:vm execution
to one worker thread per run (the workflow-workerthread engine of
PR #215, adopted as THE engine): the script's vm context moves inside
the worker, agent() bridges to ctx.subagents over the message port
(host.ts/protocol.ts/session.ts/worker.ts are new; runtime.ts loses the
abandon channel — the host's grace timer force-settles and TERMINATES
instead), start() pre-parses the body host-side to keep the seam's
synchronous SCRIPT_PARSE throw, and a ready→go handshake keeps a run
cancelled before start from ever executing the body. start() no longer
blocks the host, termination is real, and the value boundary is
serialization by construction. The package keeps its name until the
follow-up rename commit; scripts see the identical hook surface, and
the seam-contract tests hardened ahead of this swap pass unchanged.
The run and child-RPC surfaces are class-shaped rather than literal
bundles: WorkerRun IMPLEMENTS the seam's WorkflowRun (id/meta are its
own clone, separate from event payloads') and start() returns the
instance directly — interface parity with the seam is compiler-checked;
worker-side, ChildRpcBridge (implements ChildPort; callId allocation +
pending book-keeping settled by onChild* entry points) and
RpcChildHandle (every member an RPC keyed by its callId) carry names in
stacks. ChildPort's method is startAgent — it names what it starts,
matching the script-side agent() hook and the agentsStarted /
workflow/agent-* vocabulary; the Child* type names deliberately stay
(the worker side is cordis- and subagent-free; these are reduced JSON
projections, not the seam's types).
Review findings from the reference PR are folded in rather than
re-introduced:
- cancel() drives BOTH child-cancel channels host-side: the request
signal aborts AND each registered child's explicit cancel() is
called — a worker wedged in a synchronous spin cannot relay its own
ChildCancel RPCs (regression: cancel-only provider + wedged worker).
- All host warn paths render through the total renderThrown; a child
dispose() rejecting a value whose coercion throws still acks
ChildDisposed instead of wedging the script's finally (regression).
- built-worker.e2e.ts is wired into builtBinSmokeGate and the AGENTS.md
CI sequence — the built lib/worker.js resolution contract now runs in
an automated gate.
- workflow/end payload pinned on the worker-death path (with the
cancelled and grace-force-settle pins riding the ported spec).
- Real-Worker scripted timing budgets widened (50-300ms → 150-1000ms)
for starved CI hosts.
Workspace plumbing: the "./worker" subpath export sanctions the second
runtime bundle (check-workspace-constraints), tsdown builds two
single-entry passes, tsx becomes a devDependency for the unbuilt worker
spawn.
The master merge added a code-runtime/ package row while this branch adds
the timeout/ row; together they push packages/README.md over its 605-word
ceiling. Condense the timeout/ row to the terse sibling style and raise the
ceiling 605->610 for the genuinely-new package group, mirroring how the
code-runtime work raised architecture.md's ceiling in the same spirit.
The shipped backend of the code-execution seam, per the Code Mode RFC's
worker-thread section: one fresh Node worker per run, executing the
model's TypeScript after a host-side type-strip (wrapped in an
async-function shell so top-level return/await parse, sliced back out
position-preserved), bindings bridged over the message port under
hostile-peer rules (own-property name lookup, at-most-once replies,
post-settlement drops, null-prototype namespaces), logs streamed eagerly
with an in-band truncation marker, and two independent budgets — measured
event-loop busy time (computeMs) plus a never-pausing wall ceiling
(maxWallMs) — funneling into worker.terminate(). env: {} and execArgv: []
keep the isolate hermetic; disposal aborts in-flight runs and awaits
worker exits.
The worker entry loads unbuilt via Node's native type stripping
(src/worker.ts, erasable-only) and ships built as a sibling tsdown bundle
(lib/worker.js); tests/built-lib.e2e.ts pins the built load path under
plain node and joins the built-artifact smoke gate. Unit suites cover the
bootstrap in-process (fake port) and the runtime over real workers,
per-file 100%.
Model-facing tool-call budgets were tangled into each capability's schema
(bash timeoutMs, web_fetch timeout_ms) with no shared home. Add a
tools/execute around-dispatch waterfall to dsh-tools whose base next() is
the dispatch-with-normalization thunk, and a new @deepseek-ai/dsh-timeout-policy
plugin (packages/timeout/) that arms a per-tool deadline on exec.signal and
returns a structured TOOL_TIMEOUT when it wins. Migrate web_fetch (drop the
model-facing timeout_ms) and web_search onto it; the fetch provider keeps its
timeout only as a resource backstop for direct callers. bash and hook command
execution keep BASH_TIMEOUT unchanged.
Named the plugin timeout-policy (not the RFC's tool-timeout) so it does not
trip the gen-tool-catalog packages/*/tool-* completeness guard, and replace
exec.signal by in-place mutation before next() since cordis waterfall next()
ignores passed arguments. RFC moved to implemented/ recording both deviations.
Adds the missing core-data-structures coverage the catalog policy
requires for non-spine seam vocabulary: the code-runtime.md sub-page
with drift-checked type-equiv blocks for all six seam types, the core.md
sub-page row, the type-equiv manifest entries, and LINK_MAP entries so
the generated service signature links CodeRunRequest/CodeRunResult;
cordis/config catalogs regenerated.
New group packages/code-runtime/ with the interface package
@deepseek-ai/dsh-code-runtime, per the Code Mode RFC: abstract CodeRuntime
service (run() resolves program failures as an error field, rejects only
for seam misuse), the CodeRunRequest/CodeBindingNamespace/CodeRunResult/
CodeLogEntry/CodeRunFailure vocabulary, and readonly language/isolation
backend descriptors. Registered in the tsconfig maps, packages/README,
architecture service map, and the doc-graph service-role classification;
catalogs regenerated.
The RFC's one forward path token to the worker package becomes an npm-name
mention until PR3 creates that directory (verify-package-paths is
drift-scoped: the now-existing group made the token checkable).
docs/architecture.md ceiling 1630 -> 1640: the doc gained a genuinely new
capability-service row; the row itself is already minimal.
The previous commit rewrote the whole file through a JSON pretty-printer,
reformatting every existing entry; restore the established compact style with
the four new entries appended to the tools.md group.
Three Codex findings on json-schema.ts, one discipline:
- required-declared and every value check now use Object.hasOwn — 'in' let
inherited names (toString) satisfy required, dodge additionalProperties:
false, and validate a declared property against the value's prototype
member instead of a carried one
- isObjectLike now means PLAIN JSON object (proto chain of at most one link,
realm-agnostic): a Date annotation or a Map-as-properties no longer passes
structurally and serializes lossily — they fail loud as subset violations
- startInProcessRun asserts BEFORE the defensive structuredClone, so a
hostile schema fails as OutputSchemaError, never a raw DataCloneError
Also the type-equiv catalog gap: tools.md gains the structured-output subset
vocabulary (4 blocks) with matching manifest entries. The driver index also
drops the runtime internals from its public re-export (runs acquire it
internally; no external consumer remains — see the following commit).
- run-gates.ts docSyncLeafGates() gains verify-export-jsdoc — CI lanes
and the pre-push hook execute this leaf list, not the doc-sync npm
script, so the gate was previously unenforced there (proven by
SessionForkErrorCode landing undocumented via a master merge while
checks stayed green; now documented). Same wiring gap fixed for
master's verify-config-catalog, which was also missing from the list.
- The heritage exemption now recovers the base's return surface: a void
base return carried no @returns duty, so an override returning a
concrete result documents it itself (annotated overrides run the
standard check; unannotated ones are classified by the checker so
faithful void overrides need no boilerplate annotation). Three new
negative-path tests pin it; RFC and module doc updated.
- AGENTS.md states each principle inline instead of citing RFCs (eight
citations removed; high-level doc links kept) and the editing section
now carries the self-containedness rule.
- Generated catalogs/graphs regenerated for the shifted line pointers.
A name resolved through an export list (or a default-export identifier)
mapped back to its whole VariableStatement, and checkDecl walked every
declarator — so a private sibling sharing the statement with an exported
const was wrongly required to carry JSDoc.
The scope dispatch is now two-phase: requests accumulate per statement
(null = whole statement for a direct export modifier or ambient scope;
name sets union across lists, so two lists naming different declarators
of one statement both count), then each surfaced statement is checked
once with the declarator filter. Regressions pin the private-sibling
skip, the cross-list union, and the default-export sibling.
The coverage CI lane timed out (5000ms/test) in verify-export-jsdoc.spec.ts:
every test builds a ts.Program, and the fixture branch of
loadCompilerOptions omitted noLib, so each of the 34 tests parsed the
full default lib — measured 231ms/program bare, ~1.5s/test under
coverage instrumentation locally, past 5s on a 2-core runner. Fixtures
are self-contained and nothing in the walk resolves a lib symbol:
noLib + types:[] drops program creation to ~1ms and the spec's
coverage-mode test time from 53s to 0.16s. The real-repo branch
(tsconfig.base.json options) is untouched.
Codex round-3: alias prose matches the gate's strength only when the
target's own contract is prose-only. An export-import alias to a
function, class, or namespace target (or an unresolvable one) is now
refused — those carry signature/member contracts the alias cannot
hold; export the declaration directly instead. Const/enum/interface/
type-alias targets keep the self-documentation contract.
Tests pin the refusal for function, class, and namespace targets;
module doc and RFC updated.
The manifest excluded docs/tool-catalog/ and docs/persistence-catalog/ as
directories; the trailing slash is a deliberate path boundary, so the
flattened single files no longer matched and lost their generated-doc
classification — the gate would have accepted a hand-added .zh.md twin it
must reject. The entries now name the files.
Review findings on the config catalog:
The transitive-paste closure deduplicated by bare name, so two DIFFERENT
package-local declarations sharing a name would silently collapse to the
first one pasted — and a reference satisfied by the wrong declaration is a
wrong catalog, not just a thin one. Every resolution is now identity-checked
by source pointer: reaching the same declaration again is benign, while a
name that resolves to two distinct declarations, to conflicting imports, or
to a declaration in one file and an import in another is a violation — a
verbatim fence has a single flat namespace, so the fix is a rename at the
source. A spec case pins the two-declarations collision.
docs/config-catalog.md also joins the translation-pairing exclusions: it is
a generated English-only doc, and without the entry the gate would accept a
hand-added .zh.md twin it must reject.
Codex round-2 review found three adjacent fail-open shapes:
- Wrapped function expressions escaped classification: parentheses,
as/satisfies casts, and non-null assertions are now peeled before the
arrow/function test (initializers and default exports), and a
single-call-signature type literal counts as the surface signature.
A literal mixing call/construct signatures with anything else is
refused outright — no single signature to hold the tags against.
- The blanket 'export import X = N.member' skip was unsound (the target
can be a non-exported namespace member no walk visits): an alias now
documents itself.
- The heritage extra-parameter duty missed binding-pattern extras,
which no base declaration can name: they now trigger the standard
binding-pattern violation.
Five new negative-path tests pin the closed shapes; module doc and RFC
updated.
Codex round-1 review found three fail-open paths in the new gate:
- Unhandled export forms passed silently. checkDecl now fails CLOSED on
unrecognized exported statement kinds, 'export =' is refused outright,
'export import X = N.member' is an explicit documented skip (alias;
definition site owns the doc), and ambient 'declare namespace' bodies
recurse with implicit export semantics.
- Function-like exports escaped the function contract: non-identifier
default exports and consts with INLINE function-type annotations now
get full @param/@returns checks (the named-type waiver stays for
reference annotations only).
- The heritage exemption was name-only: it no longer exempts a public
override of a protected-only base member, and parameters the base
never names keep their @param duty (underscore-prefixed renames of a
base parameter count as the same parameter).
Eight new negative-path tests pin the closed gaps; RFC and module doc
updated to the refined contract.
Review findings on the config catalog:
The schema-subset check compared only top-level z.object keys against
top-level type members, so a nested loader-accepted key (agents[].id,
agentOptions.model, capabilities.*) missing from the declared type would
pass the gate unseen. The walk now collects nested object/array
compositions as key paths and resolves each against the declared config
type — through interfaces (heritage included), aliases, literals,
intersections, unions, arrays, indexed access, Partial-style wrappers, and
type references across package-local and workspace imports (re-export
chains included). The check stays presence-only and one-directional, and
only a definite miss is a violation: a path crossing a type the walk
cannot enumerate (an external package's) is skipped, never mis-reported.
The recursion guard applies at named declarations only — a structural
first child shares its span start with its parent, so a span-keyed guard
on every node mistakes ordinary descent for a cycle and silently turns
definite misses into unknowns.
The page and RFC framing also overstated the catalog as the exact
cordis.yml-settable surface: the paste is the plugin's full declared
config type, and a field the runtime schema deliberately excludes (the ACP
bridge's test-injected stream) is a runtime-only seam its own JSDoc marks.
Both now say so.
Five spec cases pin the new behavior: nested hidden key, workspace
intersection via star re-export, Partial wrapper, indexed-access
composition, and the external-type unknown path.
Master's reconstructable-requests overhaul (#179) meets the workflow tool:
- subagent-inprocess structured-output nudge becomes a system-prompt section
plus logged context (the injected-request waterfall shape is gone upstream)
- snapshot fixtures re-recorded on the merged tree so every request/header
carries the workflow tool; authored error-finish/cancel headers patched to
the merged tool list and system text
- architecture.md condensed back under its word ceiling; module graph regenerated
