# C818 — Make the principal date-state distinctions explicit

## Question

Which repeated labels need a role and construction attached?

## Inputs

```json
{}

    "MT_strict_actual_gap": 9894,
    "MT_rounded_gap": 9900
  }
}
```

## Finding

Dates must be read as state-labelled coordinates. The values9890,9894,9900 answer three different declared comparisons; identical14006 or13401 labels do not erase construction differences.

## Reassessment

Assemble the complete source-grounded synthesis draft.
