 top-level sibling of `kdf` on `ParamsFile` (`ParamsFile.second_factor`, `crates/relicario-cli/src/session.rs:125`; the `SecondFactor` enum is `crates/relicario-core/src/crypto.rs:69`).
 The `kdf` nesting is intentional — `format_version`, `aead`, and `salt_path` co-exist for forward-compat probing. Do not flatten. Production defaults: `m=65536` (64 MiB), `t=3`, `p=4`. Tests use `m=256, t=1, p=1`.
