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.

tests; no raw notification or persisted Session event format changes.
