connection binds the web transport: it injects httpServer + apiProxy and
registers toFetchHandler(ctx.apiProxy) under the /api prefix (the node:http
to fetch bridge moves in from the webserver, keeping the res-close disconnect
detection and drain/close backpressure waits). hmr owns dev reload: a
stat-poll watch per graph row driven by clientModuleHost.onGraphChanged,
rebuilt(id) on content change, and the /plugins/events SSE route (GET/HEAD
guarded); frame types are single-sourced in events.ts shared by both halves.
The node half is ClientModuleHostService (ctx.clientModuleHost): it composes
the __DSH_BOOT__ graph by scanning loader entries for dshClient packages,
serves /plugins/<id>/client.js, taps the index render, and exposes
rebuilt/onRebuilt/onGraphChanged. Scanning is incremental per package — no
full-rescan path exists: internal/plugin marks the fiber's entry name dirty,
a flush reconciles each name against live entries, package metadata
(including negative verdicts) caches forever, and re-hashing is reachable
only through rebuilt(id). The browser half moves wholesale to the standard
./client export (ClientModuleSystem, parseBootManifest with the dual-view
BootManifest, and the adoption plugin face that reads the
window.__DSH_MODULES__ slot and provides ctx.modules).
HttpServerService provides ctx.httpServer: register(route) -> disposer
(duplicate patterns throw), tapIndex transforms in registration order, and
the bound port; matching is exact > longest prefix > static dist fallback
(403/405/SPA semantics preserved). The server listens on activation, answers
per-request failures with 400 + a log line instead of exiting the process,
and knows no harness concepts — the boot graph, bundle routes, SSE channel,
and /api prefix all moved to their owning plugins.
createApiProxy moves from dsh-host-runtime into dsh-host-apiproxy (the
dependency direction already pointed this way); the package now
default-exports ApiProxyService (config {provider, model}, provides
ctx.apiProxy) while staying transport-agnostic — it registers no routes.
Runtime keeps bootHost/startHost for the headless path with its import
re-anchored, and drops the mountWebPlugins roster mounting helper.
Per-session policy overrides (sandbox/mode, approval/policy) never crossed
the delegation boundary: a spawn child of a read-only-switched parent ran
under the wider deployment default, and a fork child missed any switch made
after its seed boundary — delegation was a bypass channel for a user's
tightening.
The in-process driver now snapshots the delegating parent's override chain
and stamps it onto the child through the canonical write paths
(SandboxPolicyService.inheritOverride / ApprovalService.inheritOverride),
anchored inside the child's first turn via a one-shot agent/prompt-submit
listener: turn-enclosed (durable), ahead of the first request (an inherited
'never' reaches the child's first system prompt), and positioned after any
stale fork-seed switch so the ordinary last-event-wins fold resolves it.
Only overrides are copied — an unswitched parent stamps nothing and the
child follows the live deployment default; both services are consumed
opportunistically, so compositions without them delegate unchanged. Nesting
composes by construction (each stamp folds the already-stamped parent log).
Evidence: inheritance.spec.ts drives scripted-model children into the real
dsh-fs-sandbox fence through the real write tool (disk-state + denial-marker
assertions; spawn, stale-seed fork, grandchild, escalation fail-closed, and
no-stamp guards), inheritOverride contract tests in both service suites, and
the recorded subagent-sandbox-inheritance ACP snapshot (read-only preset →
delegate → child denied, replayed keylessly).

Second review round, both pinned red-first:
- Overlapping turn-boundary flush hints now JOIN the outstanding flush
promise (Promise.all) instead of displacing it: the SDK's
concurrent-flush guard resolves an overlapping forceFlush()
immediately, so retaining only the latest promise let shutdown()
proceed while the first export was still in flight — the same silent
drop the single-flush fix closed.
- Adoption replay contains failures per event, matching the firehose:
one rejected record is withheld fail-closed while the rest of the
historical log still hands off. Wrapping the whole loop let a single
failure silently skip the remainder on an already-adopted session.
Three review findings, each pinned by a red test first:
- The OTel backend retains the latest turn-boundary flush promise and
shutdown() awaits it before provider.shutdown(): the SDK's
concurrent-flush guard makes the shutdown-internal flush return early
while one is in flight, silently dropping everything enqueued after
the flush snapshot (including the coordinator's dispose-time shutdown
markers).
- The coordinator retires sessions from the adopted set on
session/disposed (mirroring the persistence coordinator): a long-lived
backend no longer retains closed sessions and their event logs, and
final unload no longer stamps shutdown markers for dead sessions.
- The exporter config passes through whole to OTLPLogExporter and its
type/JSDoc now advertise the full OTLPExporterNodeConfigBase shape:
rebuilding url/headers only silently dropped documented SDK options
(timeoutMillis, compression, keepAlive, ...).
tests/otel.e2e.ts self-skipped on $DSH_OTLP_E2E_ENDPOINT, which nothing in
the repo sets — it never ran; the mock-collector wire spec and the keyless
Loader-composition e2e already cover the pipeline both ways.
The severityOf compact/end probe parsed another package's merged event
shape by string comparison — an untyped cross-package contract that breaks
silently — and its only consumer was the test's own stand-in declaration.
Unknown event types now uniformly fall through as info; outcome semantics
stay with the owning package.
The seam keeps the telemetry/redact scrubbing interface but ships no rules
of its own: the innermost next() passes records through unchanged, and
deployments mount their rules as waterfall listeners. As an SDK we cannot
know which patterns are secrets in a given deployment; a shipped list
invites false confidence while catching only known shapes, and false
positives would corrupt exported bodies. Mechanism stays with the seam,
policy moves to the deployment; both READMEs and the Agent Note state the
raw-export default plainly.
The loader-composition e2e now mounts a deployment-style rule fixture and
pins the same wire behavior: secret absent, placeholder present, canonical
log untouched.
Revive the reviewed session-telemetry packages from the closed
session-telemetry-otlp-rfc branch (PR #222/#231) on current master, renamed
to @deepseek-ai/dsh-session-telemetry{,-otel} (the SDK component-telemetry
package holds the dsh-telemetry name).
Delta over the branch version: every record now passes a telemetry/redact
waterfall between projection and emit() — the innermost next() applies a
non-configurable conservative credential-shape rule set, listeners stack
stricter rules, a throwing rule withholds the record fail-closed, and the
canonical log is never rewritten. This answers the export-side concern that
closed PR #222; the boundary axiom (our aspect ends at emit(); delivery is
the reporting SDK's) is unchanged, and the runtime-telemetry RFC's outbox /
readCommitted lane is recorded as deferred in the Agent Note.
Covered by seam/redact/OTel-wire unit tiers (100% per-file) and a keyless
Loader-composition e2e that boots the examples fixture against a mock OTLP
collector and pins redaction on the wire plus the untouched canonical log.
The dev bundle watch missed rebuilds that landed while the registry was
constructing: fs.watchFile captures its comparison baseline with an
ASYNCHRONOUS first stat, so a write racing that window is absorbed into
the baseline and never reported. Standalone repro missed 24/400 same-tick
rewrites; the CI flake in web-plugins.spec.ts ('watch mode: a bundle
content change re-hashes the row...') was exactly this — the spec writes
immediately after createHostWebPluginRegistry returns.
The watch now polls from one registry-owned setInterval against a stat
baseline the scan itself captures synchronously, stat-before-read: a
write landing between stat and read leaves the hash newer than the
baseline (next tick re-hashes to the same rev, no spurious notify); a
write landing after the read leaves the baseline older (next tick
detects and notifies). No blind window. The poll iterates the live
table, so rescans retarget the watch for free and dispose clears one
timer. Stress: real-registry same-tick rewrite 0/600 missed (was 1/300);
spec watch tests 0/50.
New regression test pins the same-tick-as-construction write. Its
rewrite deliberately differs in size from the seed: a same-millisecond
same-size rewrite is invisible to any mtime+size poll (coarse fs
timestamps) — a stat-polling limit, not this regression. Loading-model
Agent Note updated in both languages (pair re-recorded).
The row rendered a status only for error, so a call cancelled before
tool/result read as a completed plan update even though no todo/write
occurred. Non-ok states now ride the generic row's StateDot semantics
(ongoing dot while running, warning dot + 已中断 marker when interrupted);
the ok badge stays for settled successful updates.
Keep inherited child prompt markers bounded by the normal silence fallback. Stage web-plugin rescans atomically and retain missing watch state until a successful rebuild.
master gave 2026-06-29-todo-write-tool a Chinese counterpart; the English
side's web-consumer sentences now translate across (in-body links keep
their .md targets per the pairing contract) and the pair is re-recorded.
The todo-panel fake gains the time/callTime fields ToolResultNode now
requires.
macOS symlinks /tmp → /private/tmp; when the session header cwd lacks
the /private prefix but fs tools resolve symlinks, tool result paths
get the prefix and the cwd replacement never matches. Strip the prefix
before cwd→{{cwd}} replacement so both forms normalize identically.
Also extend refreshFixtureReplacements to match spill paths by filename
suffix, preventing raw fixture churn when a refresh runs from a
different session directory.
additionalProperties stays true in the published schema while execute
rejected extra keys, so generated typings and validation disagreed with
runtime behavior. The item schema now declares additionalProperties:
false — the registry's arg validation rejects extra keys with a
path-qualified violation before execute runs — and the redundant manual
check is dropped (tool catalog regenerated).
repairGap installed the repulled window without the response projection;
a todo/write missed during the gap and already outside the new tail page
kept the stale list. The spec pins adoption through the repair path.
sessionHistoryValueSchema declared only events/hasMore, so the fetch
carrier's Zod parse stripped the tail page's todos projection — the
in-process and fixture paths carried it while a real WebApiClient lost it.
The fetch-carrier spec pins the field through the wire round trip.
The client's todos projection derived only from the paged display window,
so reopening a session whose last todo/write preceded the tail page showed
an empty plan until the user paged back — session-level state cannot be
reconstructed from an arbitrary window. The host owns the full log, so the
tail history response now attaches todos (latest todo/write backscan, the
same posture as the view pairing); installWindow seeds it, window rebuilds
preserve it, and any in-window or live write keeps overwriting it. The
fixture mirrors the host; docs and both Agent Notes record the mechanism.
runtime README documents ConversationSnapshot.todos and its window-scoped
limitation; the todo tool README and Agent Note name the web client among
the event consumers; the web display note records the cold-load gap and
fix directions (bilingual pair re-recorded).
The tool appends the snapshot mid-execution, between tool/call and
tool/result; the fixture spliced it after step/end with a post-turn
timestamp, so acceptance never exercised the production ordering. A spec
pins call → snapshot → result with monotonic times.
null roots, non-object roots, and null array items (retained verbatim on a
rejected tool/call) now take the documented generic-summary fallback instead
of throwing into the row error boundary.
An item carrying keys beyond content/status (ids, children, priority) was
flattened to {content, status} on append, so the logged snapshot diverged
from what the model believed it wrote (model-visible must equal logged).
Reject loudly; the isError result lets the model self-correct.
fx-alpha gains turn 63: a todo_write call/result pair plus the todo/write
snapshot event, feeding both the TodoRow toolview and the TodoPanel strip
in ?fixture mode. verify-todo-display.mjs drives chromium through panel
visibility, content, row summary, details linkage, collapse and dark.
TodoPanel pins above the composer (776px card axis), hidden while empty,
collapsible with the active item as the collapsed hint; status glyphs
mirror the TUI plan panel. todo_write rows render a plan-flavored summary
(counts + active item) via the toolview registry, generic fallback on
malformed args. Existing fake snapshots gain the required todos field.
Session consumes the todo/write session event as a per-event side effect
(last write wins), rebuilds it on window replay/paging/resync, and exposes
snapshot.todos. TodoItem re-exported through the runtime surface.
The shared test module was named harness.ts inside a repo whose product
IS a harness — hopelessly ambiguous. Renamed to scaffold.ts with
launchWebScaffold/WebScaffold; tsconfig plane-split entries, the seam
JSDoc/README mentions, and both Agent Note languages updated.
Both scenarios gain a Playwright interaction step over the settled
transcript (after the golden capture, so committed aria surfaces stay
untouched): replay-round-trip clicks the reasoning fold open/closed over
wire-delivered state; seeded-history expands a read tool row rebuilt from
the cold log and asserts the recorded result text appears (read rows are
expand-in-place — rowExpands routes the click to the inline fold, not the
details column). test:web 30 passed | 1 skipped.
The automation-only rewrite edited many implemented Agent Notes; several
edits replaced still-live or historical rationale instead of reframing:
- llm-model-catalog: restore the prompt/request consistency section and
selection-ownership alternatives — installAgentLlmTarget and the TUI
/model selector still ship that design; only the ACP wire is gone.
- plan-specific-collaboration-state, acp-multi-session, todo-write,
ask-user-question: link the superseding automation-only note instead
of silently rewriting the original decision or motivation; drop a
paragraph duplicating the Web-provider facts stated two paragraphs up.
- sandbox: stop claiming unit coverage for turn-enclosed config writes
(that mechanism left with the bridge) and retitle the commit-boundary
paragraph accordingly.
- Fix the missing blank line before '## Consequences' in the
plugin-command-registration pair, the JSON-RPC/Web render-intent
consumer misattribution (the second consumer is the host/client
runtime), stale bash_output/bash_kill names, and 'optional goals' in
architecture.md.
- examples/acp-agent/README.md: point at the package contract instead
of restating it; packages/ui/permission and plan-mode READMEs record
the consumer-less preset service and the exit_plan_mode coverage gap
under Known Limitations.
- 2026-06-19-acp-snapshot-tests: the new note defers the corpus
migration rather than committing to it; say so.
Re-record the touched bilingual pairs.
ACP v1 requires every agent to accept text AND resource_link prompt
content; the automation rewrite dropped the resource_link half of that
baseline. Restore the old bracketed-reference flattening in the codec,
reject only beyond-baseline blocks, and update the package contract and
Agent Note.
Also release the per-session prompt slot when agent.send() throws
synchronously (an agent disposed outside the bridge would otherwise
wedge the session into permanent 'already in flight' rejections),
drop the tautological version-negotiation branch, prove the scenario
env layer reaches the snapshot subprocess, pin bridge-side fail-closed
permission errors, and correct two overpromising test names.
