# C1264 — Write the source-grounded explanation of the regular kernel

## Question

## Results

```json

  "explanation": {
    "path": "deliverables/Regular_Kernel_Two_Source_Mechanisms.md",

}
```

## Finding

TheStrategy kernel now has a whole-field interpretation and an exactcalibrationcondition. The source-supportedrow andvariant mechanisms explain more than thecompactformula alone, while itsremaining sourceburden isvisible.

## Reassessment

Integrate thealreadyavailableNT comparison as a completefamily illustration rather thanopening a newgenerativecampaign.

## Checks

  "two_layers": true,
  "calibration": true,
  "historical_limit": true
}
