Reuse the existing run input for command images and ordinary queue/steer delivery.
Align Unicode command separators, bound goal observation, preserve plan input encoding,
and handle explicitly expected Windows cancellation disconnects in runtime tests.
Integrate the observed master checkpoint 7ab215e23e5d977aae7eb5d4fb91782d39969dbb without rewriting the earlier published checkpoints. Master adds current-directory events, directory-aware consumers, and retained Git worktrees; its old subagent startup paths overlapped the unified activation implementation.
Resolve directory selection within managed startup after acquiring parent ownership. Preserve the original Session origin while setting each new local child directory, retain persisted directory state on cold resume, and pass a required absolute cwd to external providers. Keep unified local/external ownership, full completion notices, parked-input host completion, SDK wait/error/shutdown behavior, and ACP cancellation semantics. Retain removal of the old in-process driver and continuation managers.
Combine SDK wait with the new directory requests, preserve the new master directory/worktree fixtures, regenerate derived catalogs from the combined sources, and refresh only the four stale prompt/schema sidecars. Preserve every protected historical schema, archived note, catalog-v2 acknowledgement, and recorded predecessor input.
Validation: full build; 59 CI static gates; 855 subagent tests with 100% coverage on changed core/external sources; affected consumer suites including 119 repaired-fixture tests; SDK 11 and headless 16 recorded scenarios; two local headless expected cases; six built nested SDK/ACP cases; lint, strict cast inventory, workspace constraints, and whitespace checks. Native Windows worker diagnostics remain additive and require the next CI run to classify the original crash.
The unified delegation tool returns as soon as an activation accepts its
prompt. SDK and ACP child runtimes could therefore reach root idle while
an admitted fork was still running. Both external providers interpreted
that idle edge as successful task completion and disposed the runtime,
returning a waiting message while cancelling the nested work.
Add the opt-in SDK session/wait request for existing SDK-owned sessions.
It waits for root idle, managed descendants, and any resulting root turns,
then requires stable idle state and Session sequence across the final
check. Preserve raw session.status notifications and HarnessSession.run's
receipt-to-next-idle API; only the task-owning SDK provider uses the new
completion operation. Subscribe before prompt admission, validate and
fold queued root events through the FIFO wait response, and retain
accepted partial output on cancellation or transport failure.
Keep ACP prompt ownership through descendant completion and later root
summary turns, including their stop reasons and output-delivery failures.
Race child waiting against the existing prompt cancellation controller;
cancellation releases the prompt without permanently closing descendant
admission or repinning the original model selection onto later turns.
Session close retains child-first descendant teardown.
Add real Loader/profile regressions with a gated nested fork for SDK and
ACP completion, cancellation, and final-summary failure. Add focused
coverage for unknown/malformed wait requests, SDK root summary ordering,
ACP cancellation followed by another prompt, and later-summary image
output draining/failure. Update the five owning bilingual README pairs.

The unchanged SDK next-idle API remains covered by its existing client
tests; no raw notification or persisted Session event format changes.
cache.spec.ts polled fire-and-forget fail-soft writes with a fixed 40ms
settle(); contended runners drain the write after the window, so the
warn/row assertions flaked. Poll the observable outcome with vi.waitFor
(5s) instead, matching the file's existing cold-read write-back pattern.
The sdk-client and subagent-dsh-sdk dispose-ladder tests passed tight
confirmation budgets (disposeGraceMs 100-300ms) to real children; on a
contended runner the SIGKILL exit edge can arrive after the budget and
close() misreports a slow reap as failure. Use the product-default
budgets (disposeGraceMs 3000ms) for the real-child cases; the fake-child
negative cases in dispose.spec.ts keep the 10ms bound.
Replace the TypeScript SDK's public arbitrary command/argv launch surface with the same-version dsh CLI, a named profile, ordered per-launch patches, optional process cwd, and explicit Harness home selection. Installed consumers use the built CLI; clean source checkouts use the package's src/bin.ts through an absolute tsx/esm loader and a source-only patch that omits build-generated Typert loading.
Materialize explicit or inherited environments at spawn time, keep profile-internal patches below caller patches, and resolve every caller-relative path before the child starts. The SDK subagent provider validates its optional CLI and patch files at plugin load and requires an isolated absolute child home.
Treat JSON-RPC initialize as the Loader-owned readiness point: Loader settlement joins entry imports, fiber lifecycle work, and synchronous effect registration, so the server needs no scheduler tick. A delayed profile entry registers a private adapter before initialize resolves, proving caller-supplied plugin routes are visible without fallback.
Update sdk-app ownership, server diagnostics, TypeScript SDK examples, nested-loader coverage, and session-upload replay layering together. The following commit contains only the regenerated SDK transcripts, keeping this API and lifecycle change directly reviewable.
