Wait, let me re-check the math. If the minimum output is 157,316 characters + 1,200 delimiters = 158,516 bytes, but the budget is only 69,000 bytes, this seems impossible. Let me verify the data again:

```json
{
  "analysis": "The math doesn't add up: 157,316 changed cells + 1,200 delimiters = 158,516 bytes minimum, but budget is 69,000. This is impossible unless I'm misunderstanding something about the data format.",
  "plan": "Re-check the frame data structure and change counts to understand what's happening.",
  "commands": [
