Improves the user experience by providing clear, inline error messages when mnemonic validation fails.
- The validation logic now captures the error message from `mnemonicToEntropy`.
- The UI displays this message directly below the invalid input field.
- This addresses the ambiguity where an input was marked as invalid (red border) without explaining why, as seen in the user-provided screenshot.
Fixes a bug where plain text mnemonics and Krux QR codes were being misidentified as encrypted SeedPGP frames.
- The `detectEncryptionMode` function has been rewritten to be stricter and now correctly identifies 'text' as a type.
- It no longer defaults to 'pgp', which was causing plain text to be treated as an encrypted format.
- The `EncryptionMode` type in `types.ts` has been updated to include 'text'.
- This resolves issues where the UI would incorrectly ask for a password for plain text mnemonics and use the wrong decryption logic for Krux QRs.
This commit addresses several issues and implements new features for the Seed Blender based on user feedback.
- **Flexible QR Scanning**: `QRScanner` is now content-agnostic. `SeedBlender` detects QR content type (Plain Text, Krux, SeedPGP) and triggers the appropriate workflow.
- **Per-Row Decryption**: Replaces the global security panel with a per-row password input for encrypted mnemonics, allowing multiple different encrypted seeds to be used.
- **Data Loss Warning**: Implements a confirmation dialog that warns the user if they try to switch tabs with unsaved data in the blender, preventing accidental data loss.
- **Final Mnemonic Actions**: Adds 'Transfer to Backup' and 'Export as QR' buttons to the final mnemonic display, allowing the user to utilize the generated seed.
- **Refactors `SeedBlender` state management** around a `MnemonicEntry` interface for robustness and clarity.
Adds the missing state declarations (`useState`) and handler functions for the dice input and final mixing steps.
The previous implementation included JSX that referenced these variables and functions before they were declared, causing a 'Can't find variable' runtime error. This commit defines the necessary state and logic to make the component fully functional.
Refactors the crypto module loading in `seedblend.ts` to be truly isomorphic and prevent browser runtime errors.
- Replaces the static Node.js `crypto` import with a dynamic `import()` inside a singleton promise (`getCrypto`).
- This ensures Vite does not externalize the module for browser builds, resolving the 'Cannot access \'crypto.webcrypto\' in client code' error.
- The browser will use its native `window.crypto`, while the Node.js test environment dynamically loads the `crypto` module.
- All tests continue to pass, verifying the fix.
Implements a new 'Seed Blender' feature that allows users to securely combine multiple BIP39 mnemonics and enhance them with dice roll entropy.
- Adds a new 'Seed Blender' tab to the main UI.
- Implements a multi-step workflow for inputting mnemonics (manual/QR) and dice rolls.
- Provides live validation and previews for blended seeds and dice-only entropy.
- Includes statistical analysis of dice rolls (chi-square, distribution) and pattern detection for quality assessment.
- The core logic is a 1-to-1 port of the reference Python implementation, using the Web Crypto API for browser compatibility and Node.js for testing.
- A full suite of unit tests ported from the reference implementation ensures correctness and deterministic outputs.
