# C876 — Evaluate the complete quarter-carrier image family

## Question

Which declared phase rows retain quarter resolution?

## Inputs

  ]
}
```

## Finding

Every source multiplier is evaluated exactly. E preserves all five quarter-grid rows; P preserves four; J preserves none. Non-quarter outputs remain valid rational diagnostics, with only source-licensed routes carrying chronology status.

## Reassessment

Derive these profiles from multiplier divisibility rather than five separate matches.

## Checks

```json
{
  "five_rows": true,
  "P_exception": true,
  "E_all": true
}
```
