Every callsite whose *real* need is "sign" or "get pubkey" should call those helpers instead of hand-rolling `load_key → decrypt_keypair → parse → sign`. Callsites that genuinely need raw PKCS8 (pairing export, bundle export, legacy rotation) must guard with `is_hardware_backend()` and return a typed error — SE keys cannot leave the enclave. +- Rotation currently hard-codes `Ed25519KeyPair` through `ring` APIs (key generation, signing the rotation event, CESR encoding). The fix re-uses `auths_id::keri::inception::generate_keypair_for_init(curve)` (already curve-aware) to produce the new pre-committed key, signs the rotation event via `auths_crypto::sign(&TypedSeed, bytes)`, and encodes CESR using the same derivation-code logic inception uses (`D` for Ed25519, `1AAJ` for P-256). Curve propagates from `ManagedIdentity` → rotation functions → storage, never re-guessed. + +**Tech Stack:** Rust (workspace), `cargo nextest`, `ring`, `p256`, `auths-crypto::TypedSeed`, `auths-keri::KeriPublicKey`, `auths-core::storage::keychain` (SE-aware helpers), Swift SE bridge (indirectly via `sign_with_handle` / `public_key_from_handle`). + +**Out of scope (do NOT touch in this plan):** +- Mobile/Python/Node binding redesign beyond adding the SE guard.
