# C810 — Close the BJ reconstruction ledger

## Question

What has the transferred grammar explained, and what has it not predicted?

## Inputs

```json
{}
```

## Sources

```json
[
  "C792–809"
]
```

## Results

```json
{
  "ledger": {
    "path": "model/BJ_reconstruction_ledger.json",
    "sha256": "12e739762a4bdcf956cb566df7178cad0a74bd27f174e42116bea1ecaf19aaa3",
    "bytes": 859
  },
  "unresolved": [
    "surface59 versus prose70",
    "surface142 versus stated147",
    "source choices are inputs, not predicted historical intent"
  ]
}
```

## Finding

BJ fits the same path grammar through insertion, contraction, residual accumulation, coarsening, and designated-component expansion. The grammar reconstructs consequences while preserving unresolved source choices and tensions.

## Reassessment

Complete the 80-step checkpoint and integrate the final synthesis.
