# Security (category index)

General security guidance (Keychain patterns, biometric auth, certificate
pinning, ATS) was removed from this library after the 2026-07 blind-test
audit confirmed current models answer it correctly without a skill
(`tools/skill-audit/`, Fable-verified coverage 0.86). What remains here is
the material models get wrong or can't know.
