El SDK CI - dev / build-and-test (pull_request) Failing after 14m43s
Cancellation-token control channel checked at every step boundary lets a coordinator PAUSE/RESUME/REDIRECT/KILL a running worker mid-task instead of waiting for the whole (possibly wrong) plan to finish. Bounded purviews mean no half-committed state to unwind on interrupt. Includes a proof harness (proof.el, run.sh) comparing a broken non-interruptible worker against the new one under identical kill/redirect/pause timing. Distinct from the already-preserved swarm-ccr orchestrator (fan-out/ converge dispatch): this is single-worker interruptibility, a complementary mechanism, not a duplicate.
