Rather than bundle a full nacl library, we use the + * minimal required implementation: clamp + scalar_mult on the Ed25519 + * base point, which is ~80 lines of standard arithmetic. + * + * CRITICAL RULES (never relax): * - The private key NEVER leaves the browser. * - The mnemonic NEVER leaves the browser. * - No key material in localStorage, sessionStorage, or cookies. - * - The private key object is marked non-extractable in WebCrypto. + * - The private CryptoKey is non-extractable. * - One document, one confirmation, one click — no batch signing. */ (function () { 'use strict'; - // ------------------------------------------------------------------------ + // ------------------------------------------------------------------------- // SESSION STATE - // Session is held in module-scope memory only. - // It is gone when the page is closed or navigated away from. - // ------------------------------------------------------------------------ + // Held in module-scope memory only.
