Follow-up to the cancellation review — harden how cancel interacts with a workstream's OWN turn and tools, not just its children and agents. - wait_for_workstream: the wait loop holds no cancel handle and blocks on the child-event bus, so a cancelled coordinator parked in a wait stayed pinned for up to WAIT_MAX_TIMEOUT (600s). Add a cooperative check to the ~2s progress heartbeat — it raises GenerationCancelled, which propagates out of the otherwise cancel-blind wait (~2s abort). - spawn_batch: stop creating the rest of the children once cancel is observed; already-spawned children stay recorded (they are live, durably parent-linked workstreams), the remainder are marked not-spawned. - session worker: only clear _worker_running if this thread is still the current worker, so a late-finishing abandoned worker (force-cancel) can't clobber a live successor's flag — which would let a third send spawn a duplicate worker on the same session. - bash silent-cancel: a SIGKILL'd silent command now records outcome-UNKNOWN (is_error, partial output kept) instead of a clean "Cancelled by user." that read as a successful empty result on replay. - wire-repair: the last-resort orphan disposition now reads outcome-UNKNOWN, matching the cooperative-cancel message (unknown, never none). Deferred: MCP / web_fetch / web_search remain uninterruptible mid-call, bounded by tool_timeout; only bash is truly preemptible.
