A test-only cordis.yml under examples/jsonrpc-agent boots the headless app
through the Loader; a scripted model delegates once to the SDK backend, whose
child is a COMPLETE second harness runtime (own cordis.yml, jsonrpc serving
surface, scripted cwd-echo model, own JSONL persistence). Asserts the parent
tool result AND the child's own persisted transcript both carry the parent
session's workspace cwd; child launch resolves through the shared
example-launch resolver so src/lib modes both hold.
SubprocessHandle loses dispose(graces) and SubprocessDisposeGraces: the
stdin-EOF→SIGTERM→SIGKILL sequence is teardown POLICY encoding one
consumer's cooperation shape, not process vocabulary — the seam keeps
kill/terminate/waitForExit, and waitForExit(signal?) is the quiescence
probe a consumer ladder needs. dsh-subagent-acp owns disposeAcpChild()
over those public verbs (tier tests move into its suite; a never-exits
stub pins the fail-loud path); dsh-subprocess-local sheds the ladder,
its deadline import, and the dsh-timeout dependency. Every future
backend now owes four verbs and no teardown policy. New bilingual
ladder-ownership Agent Note records the decision; catalogs regenerated.
- @deepseek-ai/dsh-sdk-protocol: extract the line transport from dsh-jsonrpc
and name the request/result/notification wire types both ends share; error
responses preserve wire code/data via JsonRpcResponseError.
- @deepseek-ai/dsh-sdk-client: TypeScript twin of the Python SDK — spawns the
dsh-jsonrpc-agent runtime as a subprocess, drives stdio JSON-RPC turns
(DeepSeekHarness high-level API + HarnessClient protocol client), scopes
notifications to session trees client-side, and reaps the child through the
shared subprocess dispose ladder.
- @deepseek-ai/dsh-subagent-sdk: out-of-process subagent backend driving a
child harness runtime through the TS SDK; shares cwd resolution with
subagent-acp via new dsh-subagent-subprocess cwd helpers.
- Keyless unit suites drive real subprocesses (scripted fake runtime peer);
100% per-file coverage on all touched packages.
Current-state fixes: two test comments still named the pre-rename
spawnProcess; two narrated history ('the old whole-chunk drop', 'no
longer kills backend work') instead of the pinned contract; and the
packages/README row said process-group where the seam's own vocabulary
is process-tree (en+zh, pair re-recorded).
inspect() awaited an in-flight retirement drain unconditionally before entering
serialize(), so a slow drain pinned a cancelled inspect until it finished, past
the documented cancellation boundary. Race the retirement wait against the
signal with observeQueuedAbort, matching serialize()'s queued-read behaviour.
Adds a regression that cancels an inspect while a gated retirement is pending
and asserts prompt rejection without a backend read.
After an agent-loop-only reload the server keeps its SessionRecord but the
record's agent is no longer registered. followup() no longer throws for a
detached agent, so a prompt would run against a zombie session and still report
accepted. Validate the record against the live registry before delivery, as the
ACP bridge does. Adds a regression that detaches the agent and asserts rejection.
agent/disposed only cleared the status line, so an agent-loop-only reload that
disposed the agent while the TUI stayed mounted left the local disposed flag
false. Since retained agents accept deliveries after detachment, later input
drove a zombie agent/session. Set disposed on agent/disposed so dispatchMessage
reports it. Adds a regression that sends after disposal and asserts no delivery.
Resolve merge by regenerating cordis/config catalogs and the doc graphs from
the merged tree, and re-record the tools README and tools doc bilingual pair
hashes so the pairing gate matches the merged content.
The mount-local baseline guard was seeded from "a baseline already exists in
the log", which a resumed session and a hot plugin remount both satisfy. That
made a resume skip its baseline, so offline AGENTS.md edits or removals never
reached the first resumed request — violating the documented resume contract.
Distinguish the two by agent/session-start: a startup or resume emits it before
the first step, while a remount attaches to an already-live session and never
witnesses it. Only a remount (no witnessed start, baseline already logged)
keeps the single logged baseline and skips; a resume falls through and
re-composes from current files. Adds a regression that resumes a session with
an offline baseline edit and asserts the fresh baseline reflects it.
cancel() emitted agent/cancel-requested whenever queued or steering work
existed, even under keepInbox with no active turn — a call the contract
documents as a no-op. Consumers could misread that notification as a real
cancellation. Emit only when the call actually aborts the active turn or
discards pending work, matching the "effective call" contract.
Codex review of the acp-only fix found lsp-local carries the identical
defect: its server config's unrestricted env merges into the connection's
ordinary spawn channel, so a configured DSH_* fact crashed the spawn with
the reserved-namespace rejection. The partition now lives on the seam as
splitEnvChannels() beside the scrub it complements; the ACP run and the
LSP connection both use it, and each proves child delivery end-to-end
(MOCK_ECHO_ENV / LSP_FAKE_ECHO_ENV fixture knobs). Seam + consumer README
rows updated (en+zh, re-recorded). bash-local is already two-channel;
mcp/pty/sdk bypass the seam and only share the scrub.
The acp run passed config.env wholesale into the spawn spec's ordinary
channel, which rejects the reserved DSH_* namespace — a deployment fact
like DSH_PERMISSION_MODE (the acp-agent example's own knob, used by the
with-key e2e) crashed the spawn. The run now splits DSH_* entries onto
dshEnv, where the scrubbed base expects current facts to arrive. New
layering test drives the split through the real seam via a MOCK_ECHO_ENV
knob on the mock server; README env prose updated (en+zh, re-recorded).
Implements the turndown Agent Note from the NIH dependency audit (full
variant, not the minimal entities-only fallback): dsh-tool-web's fetch
rendering now converts HTML through turndown + @joplin/turndown-plugin-gfm
(atx headings, fenced code, dash bullets, GFM tables/strikethrough) over
the real domino DOM, with script/style/noscript removed wholesale. The
hand-rolled ~86-line regex converter html.ts and its entity tables are
deleted; renderBody wraps the conversion in try/catch falling back to
the raw HTML body, because turndown's recursive DOM walk overflows with
a RangeError on pathological nesting (measured: 4k levels on the main
thread, 8k in a worker) where the regex version could never throw.
Closure weight, measured: tool-web IS in the single-exe runtime closure,
and the exe asset globs would pack ~7.9 MB of the three new packages —
but ~6 MB of that is domino's test corpus, with runtime lib/ at ~550 KB
against a ~174 MB artifact (<0.5% either way), so the swap wins.
Per testing policy the previously-missing keyless web_fetch snapshot
ships in the same change: the acp-agent `web-fetch` scenario boots a new
web.cordis.yml overlay (web seam + real dsh-web-fetch-local provider +
tool-web fetch-only + a loopback HTTP fixture server on a fixed port
serving deterministic HTML with entities, a GFM table, and nesting), so
recording and keyless replay both drive the real HTTP fetch and real
conversion end to end; the scenario pins the new `web` header class.
The Agent Note moves proposed -> implemented and is rewritten per the
lifecycle contract (Decision/Consequences/Testing, closure verdict and
alternatives recorded); tool-web and acp-agent READMEs updated in both
languages and pairs re-recorded.
The reference-admission discard listener matched on followup()'s returned id,
but an agent/inbox/enqueue listener that synchronously cancels emits
agent/inbox/discard before followup() returns to assign that id. The match
then missed, leaking both the submit and discard listeners plus the attached
context per referenced prompt. Match on the content reference instead — the
same value send() carries onto the message, known before followup() runs, and
symmetric with the submit wrapper's content check.
The prior "ordinary allowed path" test passed only because the fake agent
returned a fixed 'stub' id that collided with the id the test constructed;
it now releases each wrapper through its own allowed admission, and a new
regression drives the synchronous-discard timing directly.
CI now exports DSH_GATE_CONCURRENCY into every job, and the lsp suites
spread the raw parent env into the spawn spec's ordinary channel — which
the seam rightly rejects for DSH_* names. The specs now build their child
env the way production does (scrubbedParentEnv() + explicit extras).
The acp with-key e2e never mounted dsh-subprocess-local, leaving the
provider's inject unsatisfied, so no 'acp' provider ever registered.
Review fix (ds-review-bot on #623): matching baselines with differing
seedLength still resolve different policies — overrideOf folds own switches
past the boundary, so a stored seedLength: 1 marks event 0 as subsumed seed
history while a live seedLength: 0 lets the same event tighten the session;
adoption retained the stored header and a restart silently restored the
wide baseline. When either side carries a baseline, the seed boundary is
part of the policy identity and a mismatch rejects as an id collision.
Red-first in the shared coordinator contract (both backends).
Review fixes (ds-review-bot on #623):
- Persistence adoption compares the immutable policy baselines: onCreated's
ownerless claim and adoptLivePrefix retain the STORED header, so a
same-id live session with a conflicting baseline now rejects as a
collision instead of appending under read-only and resuming under the
stored danger-full-access.
- resolve() resolves the session override BEFORE applying an explicit
approved mode: the one-shot grant no longer bypasses the unconditional
durable-header validation.
- The approval narrator attributes positionally over the session's OWN
events (past the seed boundary): a fork child whose baseline delta has
no own override narrates 'inherited from the delegating session' instead
of misattributing a stale seed-carried switch to the user or the
operator.
Red-first: baseline-conflict adoption in the shared coordinator contract
(both backends), resolve-with-explicit-mode validation, and the fork-child
narration attribution case.
Store the captured validation error as unknown in a wrapper object and
rethrow it directly: the instanceof-Error normalization added an
un-inducible false branch that failed harness.ts's 100% branch gate.
Review fixes (ds-review-bot on #623):
- overrideOf (both knobs) rejects a seedLength past the log end before
slicing: a malformed durable boundary would otherwise empty the
own-switch slice until the log outgrew it, letting a wide baseline
shadow a REAL later tightening. Malformed durable metadata fails loud,
never open.
- The session-query derived index carries the two baseline fields end to
end: schema columns on both session tables (SESSION_QUERY_SQLITE_SCHEMA
_VERSION 6 — derived, rebuilds in place), inserts, header selects, the
candidates CTE, rowHeader, sameHeader, and the cross-source
assertSessionHeadersCompatible — so a search hit's header keeps the
child's inherited confinement and conflicting live/persisted baselines
reject.
Red-first: out-of-range seedLength tests in both policy suites;
baseline round-trip and live/persisted baseline-conflict tests in the
session-query sqlite suite.
- proposed/testing -> implemented/testing with the lifecycle rewrite
(Proposal->Decision in present tense, Acceptance criteria + Risks
folded into Consequences); zh counterpart mirrored and both pairs
re-recorded.
- the rejected NIH-audit roll-up pair now links the implemented/ path.
- loader-smoke README: captured output is bounded by execa's default
100 MB maxBuffer, no longer unbounded.
- acp-snapshot README: harness.ts now also imports vitest (vi.waitFor),
so the vitest-run-only constraint names both modules.
- jsonrpc keyless smoke: raise the invalid-env case's subprocess
deadline to 25s (the 9s pick starved a cold tsx boot on slow NFS).
Review fix (ds-review-bot on #623): the unconditional slice regressed the
public SessionStore.fork path — a generic fork child gets seedLength but no
policy baseline, so slicing discarded its seed-carried sandbox/approval
switches and silently widened it to the deployment defaults (a forked
read-only/never parent produced a workspace-write/ask child).
overrideOf now branches on baseline presence: with a header baseline (a
delegation child) the fold covers only own post-seed switches — the
baseline captured from the parent's FULL log subsumes seed history; without
one, the whole log — seeded switches ARE the replayed inherited truth. The
permission preset fold scopes the same way. Red-first: generic-fork
seed-carried override tests in both policy suites.
goal-session rides retry turns and survives admission failures. A
recovery policy closes a goal round's failed turn and reopens its
history under a retry trigger; the attempt now adopts that turn and
drops the failed turn's provisional reason, so the round settles from
the retry's own outcome instead of blocking an armed goal with
turn-error after a successful response. A downstream admission hook
that throws (rather than blocks) used to strand the queued reservation
forever; the listener now clears a still-turnless matching attempt on
the rejection path and reschedules the round.
agent-loop contains a persistently rejecting step close in the catch
path the same way the finally contains the turn close, so the
post-finally tail always publishes the terminal status — previously a
double veto escaped run(), leaving status at running while whenIdle()
resolved. The whenIdle catch arm is annotated as the backstop it now
is: every driver rejection path is contained today.
workspace-context folds an already-appended baseline from the session
log when the plugin is hot-remounted over a live session, instead of
injecting a duplicate from its fresh mount-local guard.
The TUI's reference-admission discard listener installs before
followup(): admission runs synchronously inside it on the common path,
so a listener installed afterwards missed its own cleanup and leaked
one callback per referenced prompt.
The parent branch's zh translations were recorded against its pre-reshape
en text; this PR's Node-ward en deltas get minimal zh updates across the
subprocess catalog and the subprocess/lsp-local/subagent READMEs (all
type-equiv blocks byte-identical), with pairing records re-recorded.
Responding to review on #661: a public method on the generic ToolRegistry
service whose only caller is the run_code bridge was ad-hoc surface
widening. The bridge now receives it as a registry-private capability
closure in RunCodeBridgeOptions (the requireRuntime idiom, alongside the
cap), the method is private, and it leaves the generated service
catalog/API surfaces.
The pattern is now named as a code smell where reviewers look: the
packages/AGENTS.md capability-interface rule gains the inverse-smell
clause (ceiling 660→675 — the list is at capacity and the clause needs
one sentence), and dsh-code-review's capability-fit check tells reviewers
to flag single-consumer public service methods and require the closure
form.
Implements the approved simplification Agent Note: sse.ts now pipes the
response body through TextDecoderStream and EventSourceParserStream
(eventsource-parser/stream) and keeps only the DeepSeek protocol shim —
yield each event's data, terminate on [DONE], throw
LlmError('STREAM_CLOSED') on EOF without the sentinel. The SSE
spec-conformance tests are deleted; sse.spec.ts pins only the
[DONE]/STREAM_CLOSED/EOF contract, including the new spec-strict verdict
that an unterminated trailing event is truncation (the old parser
flushed it — a robustness nicety no real provider shape needs).
eventsource-parser@^3.1.0 becomes llm-deepseek's second runtime
dependency (already in the lockfile transitively via the MCP SDK).
Docs: the Agent Note moves proposed/ → implemented/ and is rewritten per
the lifecycle contract; the rejected NIH roll-up note's inbound links
follow. The twin-adapters note, dsh-llm LlmAdapter JSDoc (and its
type-equiv fences), cookbook, group/package READMEs, root AGENTS.md
layout line, sdk-helper comments, and the regenerated config catalog
drop the "hand-rolled fetch + SSE" claim in both languages; all eight
touched pairs re-recorded.
Validate replay sidecars and cross-copy failure facts, make browser console tripwires and macOS temp paths deterministic, and wait for asynchronous TUI resume details. Keep the owning docs, translations, and generated catalog aligned.
The dedup guard pinned 'no duplicate stamp' — under the header baseline no
stamping exists, so its event-count assertion became a tautology and its
fence assertions a subset of the stale-seed case. The spec docblock claimed
the session invariants pin the stamping design (superseded); it now names
the three review-found timing threats the suite pins as distinct shapes.
Service overrideOf JSDoc shrinks to a pointer at the owning pure export.
Implements the execa Agent Note's four sub-changes:
- execa (root devDep + loader-smoke dep) replaces the hand-rolled
spawn-collect-timeout choreography in loader-smoke, apps/cli and
cli-demo/acp-demo built-bin e2e, lsp-local and code-runtime-worker
built-lib e2e, the tui pty-harness outer collector, the jsonrpc
keyless smoke, and crash-recovery's child spawn. Genuinely custom
parts stay custom: cli-demo's interrupt-on-marker, jsonrpc's
line-predicate protocol driving, crash-recovery's SIGKILL-at-failpoint.
The two loader-smoke /* v8 ignore */ OS-error branches are gone.
- llm-mock-server CLI tokenizes via node:util parseArgs; numeric
coercion/bounds/cross-option constraints stay manual; pinned
error-message tests updated to the parseArgs texts.
- both loadRootEnv copies in apps/web/tests are deleted: the owning
vitest configs (web unconditionally, snapshot in record mode)
already load the repo-root .env before these files run.
- the four poll loops (acp-snapshot harness waits + crash-recovery
waitForFile) ride vi.waitFor with explicit {interval, timeout}.
