FCA AI Live Testing · audit-grade artefacts

Evidence,
not theory.

When the supervisor asks, you hand them proof — not policy decks. Every AI system in the firm becomes a living, exportable assurance file.

UK-sovereign
by default.

Inference, data and model weights stay on UK soil. Cryptographically attested on every assurance pack — never egressed, never assumed.

FCA · PRA · UK GDPR · SM&CR

Every system.
Every rule.
Audit-ready.

Mapped to the obligations supervisors actually test against — Consumer Duty, PRA MRM (SS1/23), Operational resilience, UK GDPR, SM&CR accountability. Coverage isn't a slide. It's evidence you can hand over.
