# 21 - Verification pass catches coding drift

## Input
Any full run. To test, plant one deliberate first-pass error: an item coded to a
wrong-polarity indicator (a negative behavior coded to an effective indicator).

## Correct behavior
- The verification pass re-derives every coding from the frame text and the item summary,
  in item order, without reference to the first pass's rationale.
- The planted error surfaces as a disagreement with a proposed resolution at the coverage
  checkpoint, is resolved with the user, and the register stores only the reconciled
  coding.
- Statuses are computed only after reconciliation.

## Fail conditions
- Skipping the pass, or running it as a rubber stamp that restates the first pass.
- Computing statuses before disagreements are resolved.
