## Turn 1

Here's a thinking process:

1.  **Analyze User Input:**
   - The user wants me to return exactly a specific JSON string: `{"repeatability_probe":"ok","stable":true}`
   - There are no other instructions or questions.
   - The system prompt mentions running inside a private home-lab benchmark harness and asks to follow output format requirements exactly.

2.  **Identify Constraints:**
   - Output must be exactly: `{"repeatability_probe":"ok","stable":true}`
   - No extra text, no markdown formatting (unless specified, but "exactly JSON" usually means raw JSON).
   - I should just output that exact string.

3.  **Formulate Response:**
   - Directly output the requested JSON string.
   - Ensure no additional characters, newlines, or formatting interfere.

   Draft: `{"repeatability_probe":"ok","stable":true}`

4.  **Self-Correction/Verification:**
   - Check against constraint: "Return exactly JSON: {"repeatability_probe":"ok","stable":true}"
   - Matches perfectly.
   - No extra text.
   - Ready.✅
