Seedelf-Wallet

SecretBox (SBV1)

Password-based encryption for the wallet’s vault: Argon2id (m = 19456 KiB, t = 2, p = 1) derives a 32-byte key, and ChaCha20-Poly1305 seals the secret. The 48-byte header ("SBV1" ‖ salt(32) ‖ nonce(12)) is the AEAD associated data.

Changes made by Logical Mechanism LLC:

• Import @noble/hashes and @noble/ciphers directly instead of Lace’s @lace-lib/vendor re-exports.
• Drop the legacy EMIP-003 path (emip3.ts and its fallback in open). This wallet only ever writes SBV1.
• Move DERIVED_KEY_LEN from constants.ts into kdf.ts.
• Shorten the doc comments.

Each file names its Lace original at the top.
