## Why is there no Clarity Score for Compositionality yet?

The Clarity Score is computed from full financial filing history. Compositionality is on the official
register but outside the detailed-filing group we currently score (or awaiting its first filings), so
we show its official register record instead of a rating. Its score appears automatically once enough
filing data exists — never by payment.
