Security — Foundations Skill

Purpose

Route Keychain Services implementation tasks to the minimum required Security Knowledge Contracts. v1 scope is general (non-biometric-bound) Keychain item CRUD for kSecClassGenericPassword and kSecClassInternetPassword items — accessibility levels, access-group sharing, and storing structured/Codable data. No SecAccessControl biometric binding, no AutoFill/credential-provider extensions, no iCloud Keychain sync, no certificate/key/identity item classes.

Routing

Load only the contracts relevant to the task. All paths relative to knowledge/security/.
