Review direction (tianyicui, PR #660): in a stacked PR, change all other
process-running places to use the new service.
- lsp-local: LspConnection spawns through ctx.subprocess (piped protocol
streams + a no-spill collected stderr tail); its private process-tree
helpers (POSIX group signalling, Windows taskkill, liveness polling) are
deleted in favor of the seam's handle verbs, and its buildChildEnv now
rides scrubbedParentEnv (LSP children also stop inheriting stale DSH_*).
The plugin injects 'subprocess'; compositions/tests mount
dsh-subprocess-local.
- subagent-acp: the ACP child spawns through the seam (piped ndjson streams,
inherited stderr); spawn failure surfaces through done-rejection into the
same startup race; disposal is handle.dispose with the plugin's configured
graces. dsh-subagent-subprocess is DELETED — its dispose ladder and scrub
are the seam's, and the isolated-config-dir helper had no consumer.
- mcp-client, pty-local, sdk-helper: adopt scrubbedParentEnv as the one
scrub definition (their spawns stay put by ownership: the MCP SDK and
node-pty own those calls; the SDK wizard runs outside any composition).
- Coverage: per-file 100% over every touched src file, with each v8 ignore
carrying a platform or contract reason; new suites cover stdio
dispositions, the dispose ladder tiers, injected-win32 tree semantics,
waitForExit, settled-kill/terminate no-ops, and spawn-failure disposal.
- Docs: consumer-migration Agent Note (en; zh follows in this PR), seam note
updated in place, subprocess.md rewritten for the reshaped vocabulary
(type-equiv re-registered), READMEs and SERVICE_ROLES updated, taskkill
added to knip ignoreBinaries.
A well-formed provider stream that ends with finish_reason stop and zero
content blocks previously became a successful empty assistant message: the
turn completed silently, and drivers like goal-session counted the no-op
round. Both adapters now map that degenerate completion to a finish
{kind:'error'} with the new canonical EMPTY_RESPONSE code from dsh-llm, and
dsh-llm-retry adds the code to its default retryable set, so the existing
closed-step recovery path retries it and fails loud once the budget is
exhausted.
Covered by adapter unit tests, an llm-retry default-policy test, and a new
authored keyless ACP snapshot (empty-response-retry) with a deterministic
1 ms zero-jitter retry overlay.
Address a second fresh-eye review of the review fixes:
- MAJOR: late steering that lands after runTurn returns terminally
stopped (e.g. during the post-turn flush) was drained by runLoop and
dropped without a discard, leaving a dangling outstanding id the
negative-only invariant can't catch. Emit agent/inbox/discard for it,
symmetric with the in-turn terminal-stop drop.
- remove the dead cancel() idle-settle branch: whenIdle's fast path
already resolves for a lone quiet item, so no waiter is ever left for
it to settle. Document why.
- gen-cordis-api classShape now drops private/protected/#private members
and strips getter/setter bodies, so Session no longer leaks private
fields and getter bodies into the model catalog.
- document that AgentMessage intentionally omits meta (durable-only).
Adds a regression test for the late-steering discard.
Resolve six review findings on the unified-send change:
- quiet (wakeup:false) queued items no longer un-park the driver; the
inbox distinguishes hasWakingQueued (drives the loop, idle/quiescence)
from hasQueued (anything to dequeue), so a lone quiet item parks at idle
and rides the next waking send. whenIdle/cancel settle off the waking
signal, so cancelling a parked quiet item no longer hangs whenIdle.
- SendOptions.meta on queued/steering sends now reaches the durable
user/message and steering/message (was dropped except on injection).
- a terminal agent/turn-stop that drops pending steering emits
agent/inbox/discard so the enqueue-dequeue-or-discard ledger balances.
- the loop-authored continuation reason is snapshotted and frozen like a
public send.
- gen-cordis-api collects exported classes (body-stripped) so the now-
abstract-class Agent and its transitive shapes reappear in the API
catalog.
Adds regression tests for each and re-records the affected snapshot.
Merge took master's snapshot fixtures; re-record the two keyless
scenarios so they reflect this branch's user/message coalescing and the
abstract Agent + AgentMessageId type dump.
Replace send/steer/inject with one Agent.send primitive over the
(target × wakeup) matrix; followup/steer/inject become fixed-preset
alias methods on the now-abstract Agent class. Coalesce context/message
into user/message (injected context is a non-user source). Replace
agent/queued with agent/inbox/enqueue/dequeue/discard, add cancel
keepInbox, and add a FIFO-conservation invariant.
