Coverage data methodology
How CoverProof turns source register data into cautious public context for Section 250 role maps and checks.
The coverage asset exists to make source context visible and auditable. It is not a shortcut around a firm-specific Section 250 analysis. Public surfaces render only bounded, source-backed context and keep legal conclusions out of the data layer.
Source inputs
CoverProof starts from FCA register source data and internal coverage-asset rows derived from that source. Public pages use this data only as source-role context: role counts, source dates, methodology version, and output hashes.
Provenance and hashes
Each renderable asset-derived claim must carry a source date, registered methodology version, output hash prefix, and legal-safety caveat. If any of those fields are missing, the public surface hides the asset-derived context instead of filling the gap with copy.
Freshness
Freshness is measured from the source data date and retrieval time. A fresh retrieval does not make the underlying register data newer; source lag is reported separately where it is available.
Limits
The coverage asset is not an FCA endorsement, not complete market coverage, not a market benchmark, and not a legal conclusion about any firm or role. It helps readers understand source context before a firm-specific analysis.
Benchmark caveats
Source limits
Benchmark context is calculated only from coverage-asset rows with complete provenance. It is source context, not complete market coverage or an FCA dataset.
Sample-size caveat
Published benchmark context reflects the current qualified sample only. Low-count, stale, or mixed-provenance samples are suppressed instead of being stretched into market-wide claims.
Freshness
Freshness is tied to the source date range and retrieval time. A new retrieval does not make the underlying register data newer.
Methodology and hashes
Renderable stats must carry a methodology version and output hash prefix. Missing or mixed provenance suppresses the benchmark output.
Claim boundary
Asset-derived aggregate benchmark context only; sample-size caveat applies; no certainty, not FCA endorsement, not complete market coverage, not a market benchmark, and not a legal conclusion.
No-certainty caveat
Benchmark figures are directional context for interpreting source-role coverage. They do not certify a firm, predict a regulator or court outcome, or prove Section 250 compliance.
