 | P1 | Inference contract 6: the `tools` array is fixed per epoch. `find_tool` returns schemas as a tool result and the model calls them through a `call_tool(name, arguments)` meta-tool. Never instruct the model to call an undeclared tool. | M0 (h): adding a tool re-read the whole prompt; undeclared calls were coerced into `write_file`. |
+| P2 | Inference contract 2: the session log stores assistant messages exactly as returned, including `reasoning_content`, and replays them unchanged. Remove the "known risk" about dropped thinking blocks. | M0 (e): Ornith's template keeps every think block. |

 | P3 | Inference contract 7: requests set `return_progress: true`; progress events count as liveness. | M0 (i): otherwise the stream is silent during prefill. |
