The data source this signal was derived from, normalised to the four public API-level sources. One of:

• COMPANIES_HOUSE — sourced from Companies House (registry filings, officer data, etc.).
• GAZETTE — sourced from The Gazette (official UK public record — insolvency notices, etc.).
• REGISTRY_TRUST — sourced from Registry Trust (County Court Judgments and other debt registry records).
• GRAND — Grand-derived or Grand-curated; catch-all for non-authoritative sources including court filings, news/press, and manual overrides.

The kind of early-warning signal. These are credible, pre-threshold indicators; they never by themselves change the company's trading status. One of:

• FILING_TRAJECTORY — short-term deterioration in statutory filing position (filings due within 30 days).

• APPOINTMENT_OF_RECEIVER — a secured lender is enforcing a charge over company assets via a receiver.
• PROPERTY_CHARGE_ENFORCEMENT — assets have been seized or realised to repay secured debt.
• FAILURE_TO_FILE_ACCOUNTS — escalated statutory non-compliance beyond routine overdue filings (Gazette notice).
• OFFICER_UBO_CHANGE — a change to a registered officer or person with significant control.
• ENTITY_TYPE_CHANGE — a change to the registered legal entity type at Companies House.
• BUSINESS_DETAILS_CHANGE — a change to the registered business name, address, or other core details.
