## Finding

All100 authorized actions are complete, with a reassessment after each. The cycle delivers a constructive explanation across complete list,inverse,NT,Key and carrier families, integrated with the inherited regular,cumulative,Rounded and BJ mechanisms.

## Reassessment

Run the final100-action replay, package and save the sealed result. C932 remains unused.

## Checks

```json
{
  "contiguous99": true,
  "exact100": true,
  "gate_PASS": true,
  "gate_binding": true,
  "artifacts_present": true,
  "latest_source": true
}
