# C835 — Recover both complete Tishri margins

## Question

Do event-category and species totals measure the same frozen count matrix?

## Inputs

```json
{}
```

## Sources

```json
[
  "File58 §3.1 literal category table"
]
```

## Results

```json
{
  "matrix": {
    "path": "model/Tishri_count_matrix.json",
    "sha256": "ccbb58ccd547dbe8e826eba227e09d3454451f998f4531f34677c06ee73375c2",
    "bytes": 665
  },
  "category_totals": [
    44,
    6,
    11,
    10,
    10,
    189,
    10
  ],
  "species_totals": [
    75,
    18,
    176,
    11
  ],
  "grand_total": 280
}
```

## Finding

The two280 totals are different marginals of one seven-by-four matrix. Their agreement is forced by the shared ledger, while the chosen categories and entries remain source inputs.

## Reassessment

Determine what the margins preserve and what they cannot recover.

## Checks

```json
{
  "literal_rows": true,
  "literal_cols": true,
  "same_total": true
}
```
