After fix of the exec-frame refusal regression, bridge tools execute under the run signal only. A future composed abort (AbortSignal.any of run + request signals threaded through a dual-signal factory contract) was evaluated and deliberately deferred: its request leg is empty on every reachable teardown path today (requestAbortController.abort only fires on caller abort and idle timeout, and the idle path re-arms during local work). Revisit if a real request-scoped teardown path appears. (2026-08-20 hyperdebate consensus.)
