Replace the no-op on_next handlers in _setup_node_stream_subscriptions with factory-created callbacks that look up and invoke the per-node sync_executor registered by _register_node_executor. The previous code silently discarded every message delivered to node streams. Key changes: - Wire on_next to executor via _make_on_next_handler factory method - Store executors in _node_executors dict (not setattr on stream_router) - Shared ThreadPoolExecutor with proper lifecycle (start/stop/restart) - Prefer run_coroutine_threadsafe when scheduler loop is running; fall back to thread pool with deadlock prevention - Thread-safe StateManager: Lock on all mutation methods, deep-copy emission inside lock for immutable subscriber snapshots - replace_state() and reset() deep-copy input to prevent external mutation bypassing the lock (review cycle 5 M1 fix) - Best-effort cancellation documented on timed-out futures (cycle 5 M2) - CancelledError catch in thread pool path with "graph stopping" message - is_running guard on both sync_executor and execute() entry point - Checkpoint filenames include update_count to prevent collisions - _save_checkpoint docstring warns against calling while _lock is held - on_next handler distinguishes TimeoutError (warning) from other exceptions (exception log) for clearer diagnostics - TODO comment for deferred downstream propagation to successor nodes - __del__ safety net for executor pool cleanup - File I/O outside lock for checkpoint save/load - Bounded execution_history via collections.deque(maxlen=1000) See PR !10795 for the full change log across 5 review cycles.

freemo	b2e923173f	perf(tests): consolidate 141 trivially small feature files into 34 domain groups ... Consolidate 141 BDD feature files that each complete in under 0.1 seconds into 25 domain-grouped feature files, reducing subprocess count from 339 to ~223. Each consolidated file groups scenarios from the same domain/module that share step definitions and fixtures. All scenarios are preserved with clear comment headers indicating their original source file. This reduces subprocess overhead by ~116 invocations (141 original files replaced by 25 consolidated files), targeting the 42% of subprocess count that contributed only 0.2% of actual test runtime.
