## Why is there no Clarity Score for Maritime Archaeology Sea Trust yet?

The Clarity Score is computed from full financial filing history. Maritime Archaeology Sea Trust 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.
