+### Step 660: `whetstone_generate_inference_job` MCP tool
+**Status:** PASS (12/12 tests)
+
+Adds inference-job generation model for entropy observations with structured
+job payload output (`type`, `goal`, `context.files`, `context.entropy_score`,
+`bounty`) and input validation/error signaling.
+
+**Files added:**
+- `editor/src/InferenceJobGenerator.h` - inference-job generator model
+- `editor/tests/step660_test.cpp` - 12 tests for generation and validation paths
+
+**Files modified:**
