# C1475 — Replay the complete mathematical comparison independently

## Question

Does numeric digit reversal and exact rational arithmetic reproduce all recorded model results and their bound sources?

## Sources

```json
[
  "verify_cycle.py",
  "All arithmetic models",
  "Source bindings"
]
```

## Results

```json
{
  "status": "PASS",
  "checks": 243,
  "bound_sources": 15,
  "method": "Independent arithmetic digit reversal using integer divmod; exact fractions; research.digest-compatible canonical JSON hashes.",
  "editorial_metadata_remaining": [
    "reader_integration.json"
  ]
}
```

## Finding

Independent arithmetic replay passes, including all eighteen paths, exact Key relations and signed counterexamples; the source bindings and sequential chain agree.

## Reassessment

Verify the reader artifact hashes and formatting separately from the arithmetic models.

## Checks

```json
{
  "replay_pass": true,
  "zero_failures": true
}
```
