+### Step 654: HiveMind job publisher from editor
+**Status:** PASS (12/12 tests)
+
+Adds a dispatch publisher model for `whetstone_dispatch_to_hivemind` style flow,
+covering taskitem validation, nexus queue signal, and MQTT topic publish signal.
+
+**Files added:**
+- `editor/src/HiveMindJobPublisher.h` - dispatch publisher model
+- `editor/tests/step654_test.cpp` - 12 tests for dispatch validation/publish flow
+
+**Files modified:**
+- `editor/CMakeLists.txt` - `step654_test` target
+
+**Verification run:**
+- `cmake -S editor -B editor/build-native` - PASS
