CHFUCompanies House Filings (UK)

UK Companies House filing punctuality + governance disclosure for {legal_name}. EXTRACTION RULES: Cite find-and-update.company-information.service.gov.uk. Return composite_signal {filing_punctuality, filing_completeness, registry_status_active} (each 0-100 + source_url). SUB-SIGNAL OBSERVABILITY (anti-fabrication, MANDATORY): registry EXISTENCE/status is almost always verifiable, but the deposited-accounts CONTENT (filing_punctuality / filing_completeness) is frequently paywalled, fee-gated, or simply not deposited for small/private companies. If you cannot OBSERVE the actual filing dates or document richness from a CITED source, return that sub-signal as null — do NOT estimate or guess a band from the company's size, sector or country, and do NOT treat a paywalled/undisclosed content sub-signal as "low". registry_status_active must be scored ONLY from a POSITIVE registry hit you cite (the status field visible); if you cannot locate the entity in Companies House at all (ambiguous legal name, homonym, no hit), do NOT default it to active — return it null. Not-found is NOT active. If NO sub-signal could be observed from any cited source, return type="absent" reason="no_company_specific_data" (a genuine content-absence then resolves to a clean not_applicable, never a fabricated composite).
