# C908 — Build the explanatory constraint ledger

## Question

Which agreements follow automatically and which require particular source inputs?

## Inputs

```json
{}
```

## Sources

```json
[
  "C832–907 complete-family results"
]
```

## Opened utc

## Results

```json
{
  "ledger": {
    "path": "model/explanatory_constraint_ledger.json",
    "sha256": "f8eee370994066bfd9f3fb220940c564a163f6bd1555f6020d9fc139c7a0c40d",
    "bytes": 1279
  }
}
```

## Finding

The model separates algebraic consequences from source-dependent placements, weights and roles. Regenerated coordinates are linked consequences of shared inputs, not independent witnesses to the source choices.

## Reassessment

Identify the finite necessity evidence for the information retained by the grammar.

## Checks

```json
{
  "six_domains": true,
  "source_residual_everywhere": true
}
```
