-# Development Guide - SeedPGP v1.1.0
-
-## Architecture Quick Reference
-
-### Core Types
-
-```typescript
-// src/lib/types.ts
-interface SeedPgpPlaintext {
-  v: number;              // Version (always 1)
-  t: string;              // Type ("bip39")
-  w: string;              // Mnemonic words (normalized)
-  l: string;              // Language ("en")
-  pp: number;             // BIP39 passphrase used? (0 or 1)
-  fpr?: string[];         // Optional recipient fingerprints
-}
-
-interface ParsedSeedPgpFrame {
-  kind: "single";         // Frame type
-  crc16: string;          // 4-digit hex checksum
-  b45: string;            // Base45 payload
-}
-```
-
-### Frame Format
-
-```
-SEEDPGP1:0:ABCD:BASE45DATA
-
-SEEDPGP1 - Protocol identifier + version
-0        - Frame number (single frame)
-ABCD     - CRC16-CCITT-FALSE checksum (4 hex digits)
-BASE45   - Base45-encoded PGP binary message
-```
-
-### Key Functions
-
-#### Encryption Flow
-```typescript
-buildPlaintext(mnemonic, bip39PassphraseUsed, recipientFingerprints?)
-  → SeedPgpPlaintext
-
-encryptToSeedPgp({ plaintext, publicKeyArmored?, messagePassword? })
-  → { framed: string, pgpBytes: Uint8Array, recipientFingerprint?: string }
-```
-
-#### Decryption Flow
-```typescript
-decryptSeedPgp({ frameText, privateKeyArmored?, privateKeyPassphrase?, messagePassword? })
-  → SeedPgpPlaintext
-
-frameDecodeToPgpBytes(frameText)
-  → Uint8Array (with CRC16 validation)
-```
-
-#### Encoding/Decoding
-```typescript
-frameEncode(pgpBinary: Uint8Array) → "SEEDPGP1:0:CRC16:BASE45"
-frameParse(text: string) → ParsedSeedPgpFrame
-frameDecodeToPgpBytes(frameText: string) → Uint8Array
-```
-
-### Dependencies
-
-```json
-{
-  "openpgp": "^6.3.0",      // PGP encryption (curve25519Legacy)
-  "bun-types": "latest",    // Bun runtime types
-  "react": "^18.x",         // UI framework
-  "vite": "^5.x"            // Build tool
-}
-```
-
-### OpenPGP.js v6 Quirks
-
-⚠️ **Important compatibility notes:**
-
-1. **Empty password array bug**: Never pass `passwords: []` to `decrypt()`. Only include if non-empty:
-   ```typescript
-   if (msgPw) {
-     decryptOptions.passwords = [msgPw];
-   }
-   ```
-
-2. **Curve naming**: Use `curve25519Legacy` (not `curve25519`) in `generateKey()`
-
-3. **Key validation**: Always call `getEncryptionKey()` to verify public key has usable subkeys

-
-## Feature Agenda
-
-### 🚧 v1.2.0 - QR Code Round-Trip
-
-**Goal**: Read back QR code and decrypt with user-provided credentials
-
-**Tasks**:
-- [ ] Add QR code generation from `encrypted.framed`
-  - Library: `qrcode` or `qr-code-styling`
-  - Input: SEEDPGP1 frame string
-  - Output: QR code image/canvas/SVG
-  
-- [ ] Add QR code scanner UI
-  - Library: `html5-qrcode` or `jsqr`
-  - Camera/file upload input
-  - Parse scanned text → `frameText`
-  
-- [ ] Build decrypt UI form
-  - Input fields:
-    - Scanned QR text (auto-filled)
-    - Private key (file upload or paste)
-    - Key passphrase (password input)
-    - OR message password (alternative)
-  - Call `decryptSeedPgp()`
-  - Display recovered mnemonic + metadata
-  
-- [ ] Add visual feedback
-  - CRC16 validation status
-  - Key fingerprint match indicator
-  - Decryption success/error states
-
-**API Usage**:
-```typescript
-// Generate QR
-import QRCode from 'qrcode';
-const { framed } = await encryptToSeedPgp({ ... });
-const qrDataUrl = await QRCode.toDataURL(framed);
-
-// Scan and decrypt
-const scannedText = "SEEDPGP1:0:ABCD:..."; // from scanner
-const decrypted = await decryptSeedPgp({
-  frameText: scannedText,
-  privateKeyArmored: userKey,
-  privateKeyPassphrase: userPassword,
-});
-console.log(decrypted.w); // Recovered mnemonic
-```
-
-**Security Notes**:
-- Never log decrypted mnemonics in production
-- Clear sensitive data from memory after use
-- Validate CRC16 before attempting decrypt
-- Show key fingerprint for user verification
-
----
-
-### 🔮 Future Ideas (v1.3+)
-
-- [ ] Multi-frame support (for larger payloads)
-- [ ] Password-only (SKESK) encryption flow
-- [ ] Shamir Secret Sharing integration
-- [ ] Hardware wallet key generation
-- [ ] Mobile companion app (React Native)
-- [ ] Printable paper backup templates
-- [ ] Encrypted cloud backup with PBKDF2
-- [ ] BIP85 child mnemonic derivation
-
-## Debugging Tips
-
-### Enable verbose PGP logging
-
-Uncomment in `seedpgp.ts`:
-```typescript
-console.log("Raw PGP hex:", Array.from(pgpBytes).map(...));
-console.log("SeedPGP: message packets:", ...);
-console.log("SeedPGP: encryption key IDs:", ...);
-```
-
-### Test with known vectors
-
-Use Trezor vectors from test file:
-```bash
-bun test "Trezor"  # Run only Trezor tests
-```
-
-### Validate frame manually
-
-```typescript
-import { frameParse } from "./lib/seedpgp";
-const parsed = frameParse("SEEDPGP1:0:ABCD:...");
-console.log(parsed); // Check structure
-```
-
-## Code Style
-
-- **Functions**: Async by default, explicit return types
-- **Errors**: Throw descriptive Error objects with context
-- **Naming**: `camelCase` for functions, `PascalCase` for types
-- **Comments**: Only for non-obvious crypto/encoding logic
-- **Testing**: One test per edge case, descriptive names
-
-## Git Workflow

+## 🛡️ Explicit Threat Model Documentation
+
+### 🎯 What SeedPGP Protects Against (Security Guarantees)
+
+SeedPGP is designed to protect against specific threats when used correctly:
+
+| Threat | Protection | Implementation Details |
+|--------|------------|------------------------|
+| **Accidental browser storage** | Real-time monitoring & alerts for localStorage/sessionStorage | StorageDetails component shows all browser storage activity |
+| **Clipboard exposure** | Clipboard tracking with warnings and history clearing | ClipboardDetails tracks all copy operations, shows what/when |
+| **Network leaks** | Strict CSP headers blocking ALL external requests | Cloudflare Pages enforces CSP: `default-src 'self'; connect-src 'none'` |
+| **Wrong-key usage** | Key fingerprint validation prevents wrong-key decryption | OpenPGP.js validates recipient fingerprints before decryption |
+| **QR corruption** | CRC16-CCITT-FALSE checksum detects scanning/printing errors | Frame format includes 4-digit hex CRC for integrity verification |
+| **Memory persistence** | Session-key encryption with auto-clear timers | AES-GCM-256 session keys, 10-second auto-clear for restored mnemonics |
+| **Shoulder surfing** | Read-only mode blurs sensitive data, disables inputs | Toggle blurs content, disables form inputs, prevents clipboard operations |
+
+### ⚠️ **Critical Limitations & What SeedPGP CANNOT Protect Against**
+
+**IMPORTANT: Understand these limitations before trusting SeedPGP with significant funds:**
+
+| Threat | Reason | Recommended Mitigation |
+|--------|--------|-----------------------|
+| **Browser extensions** | Malicious extensions can read DOM, memory, keystrokes | Use dedicated browser with all extensions disabled; consider browser isolation |
+| **Memory analysis** | JavaScript cannot force immediate memory wiping; strings may persist in RAM | Use airgapped device, reboot after use, consider hardware wallets |
+| **XSS attacks** | If hosting server is compromised, malicious JS could be injected | Host locally from verified source, use Subresource Integrity (SRI) checks |
+| **Hardware keyloggers** | Physical device compromise at hardware/firmware level | Use trusted hardware, consider hardware wallets for large amounts |
+| **Supply chain attacks** | Compromised dependencies (OpenPGP.js, React, etc.) | Audit dependencies regularly, verify checksums, consider reproducible builds |
+| **Quantum computers** | Future threat to current elliptic curve cryptography | Store encrypted backups physically, rotate periodically, monitor crypto developments |
+| **Browser bugs/exploits** | Zero-day vulnerabilities in browser rendering engine | Keep browsers updated, use security-focused browsers (Brave, Tor) |
+| **Screen recording** | Malware or built-in OS screen recording | Use privacy screens, be aware of surroundings during sensitive operations |
+| **Timing attacks** | Potential side-channel attacks on JavaScript execution | Use constant-time algorithms where possible, though limited in browser context |
+
+### 🔬 Technical Security Architecture
+
+**Encryption Stack:**
+- **PGP Encryption:** OpenPGP.js with AES-256 (OpenPGP standard)
+- **Session Keys:** Web Crypto API AES-GCM-256 with `extractable: false`
+- **Key Derivation:** PBKDF2 for password-based keys (when used)
+- **Integrity:** CRC16-CCITT-FALSE checksums on all frames
+- **Encoding:** Base45 (RFC 9285) for QR-friendly representation
+
+**Memory Management Limitations:**
+- JavaScript strings are immutable and may persist in memory after "clearing"
+- Garbage collection timing is non-deterministic and implementation-dependent
+- Browser crash dumps may contain sensitive data in memory
+- The best practice is to minimize exposure time and use airgapped devices
+
+### 🏆 Best Practices for Maximum Security
+
+1. **Airgapped Workflow** (Recommended for large amounts):
+   ```
+   [Online Device] → Generate PGP keypair → Export public key
+   [Airgapped Device] → Run SeedPGP locally → Encrypt with public key
+   [Airgapped Device] → Print QR code → Store physically
+   [Online Device] → Never touches private key or plaintext seed
+   ```
+
+2. **Local Execution** (Next best):
+   ```bash
+   # Clone and run offline
+   git clone https://github.com/kccleoc/seedpgp-web.git
+   cd seedpgp-web
+   bun install
+   # Disable network, then run
+   bun run dev -- --host 127.0.0.1
+   ```
+
+3. **Cloudflare Pages** (Convenient but trust required):
+   - ✅ Real CSP enforcement (blocks network at browser level)
+   - ✅ Security headers (X-Frame-Options, X-Content-Type-Options)
+   - ⚠️ Trusts Cloudflare infrastructure
+   - ⚠️ Requires HTTPS connection
+
+---
+
+## 📚 Simple Usage Examples
+
+### Example 1: Password-only Encryption (Simplest)
+
+```typescript
+import { encryptToSeed, decryptFromSeed } from "./lib/seedpgp";
+
+// Backup with password
+const mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about";
+const result = await encryptToSeed({
+  plaintext: mnemonic,
+  messagePassword: "MyStrongPassword123!",
+});
+
+console.log(result.framed); // "SEEDPGP1:0:ABCD:BASE45DATA..."
+
+// Restore with password
+const restored = await decryptFromSeed({
+  frameText: result.framed,
+  messagePassword: "MyStrongPassword123!",
+});
+
+console.log(restored.w); // Original mnemonic
+```
+
+### Example 2: PGP Key Encryption (More Secure)
+
+```typescript
+import { encryptToSeed, decryptFromSeed } from "./lib/seedpgp";
+
+const publicKey = `-----BEGIN PGP PUBLIC KEY BLOCK-----
+... your public key here ...
+-----END PGP PUBLIC KEY BLOCK-----`;
+
+const privateKey = `-----BEGIN PGP PRIVATE KEY BLOCK-----
+... your private key here ...
+-----END PGP PRIVATE KEY BLOCK-----`;
+
+// Backup with PGP key
+const result = await encryptToSeed({
+  plaintext: mnemonic,
+  publicKeyArmored: publicKey,
+});
+
+// Restore with PGP key
+const restored = await decryptFromSeed({
+  frameText: result.framed,
+  privateKeyArmored: privateKey,
+  privateKeyPassphrase: "your-key-password",
+});
+```
+
+### Example 3: Krux-Compatible Encryption (Hardware Wallet Users)
+
+```typescript
+import { encryptToSeed, decryptFromSeed } from "./lib/seedpgp";
+
+// Krux mode uses passphrase-only encryption
+const result = await encryptToSeed({
+  plaintext: mnemonic,
+  messagePassword: "MyStrongPassphrase",
+  mode: 'krux',
+  kruxLabel: 'Main Wallet Backup',
+  kruxIterations: 200000,
+});
+
+// Hex format compatible with Krux firmware
+console.log(result.framed); // Hex string starting with KEF:
+```

-- ✅ Frame format validation
-- ✅ CRC16 integrity checking
+---
 
-## Security Considerations
-
-### ✅ Best Practices
-
-- Uses **AES-256** for symmetric encryption
-- **cv25519** provides ~128-bit security level
-- **CRC16** detects QR scan errors (not cryptographic)
-- Key fingerprint validation prevents wrong-key usage
-- **Session-key encryption**: Ephemeral AES-GCM-256 for in-memory protection
-- **CSP headers**: Browser-enforced network blocking via Cloudflare Pages
-
-### ⚠️ Important Notes
-
-- **Never share your private key or encrypted QR codes publicly**
-- Store backup QR codes in secure physical locations (safe, safety deposit box)
-- Use a strong PGP key passphrase (20+ characters)
-- Test decryption immediately after generating backups
-- Consider password-only (SKESK) encryption as additional fallback
-
-### 🔒 Production Deployment Warning
-
-The Cloudflare Pages deployment at **<https://seedpgp-web.pages.dev>** is for:
-
-- ✅ Personal use with enhanced security
-- ✅ CSP enforcement blocks all network requests
-- ✅ Convenient access from any device
-- ⚠️ Always verify the URL before use
-
-For maximum security with real funds:
-
-- Run locally: `bun run dev`
-- Or self-host on your own domain with HTTPS
-- Use an airgapped device for critical operations
-
-### Threat Model (Honest)
-
-**What we protect against:**
-
-- Accidental persistence to localStorage/sessionStorage
-- Plaintext secrets lingering in React state after use
-- Clipboard history exposure (with warnings)
-
-**What we DON'T protect against:**
-
-- Active XSS or malicious browser extensions
-- Memory dumps or browser crash reports
-- JavaScript garbage collection timing (non-deterministic)

+## SeedPGP Recovery Playbook - Offline Recovery Guide
+
+**Generated:** Feb 3, 2026 | **SeedPGP v1.4.4** | **Frame Format:** `SEEDPGP1:0:CRC16:BASE45_PAYLOAD`
+
+***
+
+## 📋 Recovery Requirements
+
+```
+✅ SEEDPGP1 QR code or printed text  
+✅ PGP Private Key (.asc file) OR Message Password (if symmetric encryption used)
+✅ Offline computer with terminal access
+✅ gpg command line tool (GNU Privacy Guard)
+```
+
+**⚠️ Important:** This playbook assumes you have the original encryption parameters:
+
+- PGP private key (if PGP encryption was used)
+- Private key passphrase (if the key is encrypted)
+- Message password (if symmetric encryption was used)
+- BIP39 passphrase (if 25th word was used during backup)
+
+***
+
+## 🔓 Step 1: Understand Frame Format
+
+**SeedPGP Frame Structure:**
+
+```
+SEEDPGP1:0:CRC16:BASE45_PAYLOAD
+```
+
+- **SEEDPGP1:** Protocol identifier
+- **0:** Frame version (single frame)
+- **CRC16:** 4-character hexadecimal CRC16-CCITT checksum
+- **BASE45_PAYLOAD:** Base45-encoded PGP binary data
+
+**Example Frame:**
+
+```
+SEEDPGP1:0:58B5:2KO K0S-U.

+PAYLOAD=$(echo "$FRAME" | cut -d: -f4-)
+echo "$PAYLOAD" > payload.b45
+```
+
+***
+
+## 🔓 Step 2: Decode Base45 → PGP Binary
+
+**Option A: Using base45 CLI tool:**
+
+```bash
+# Install base45 if needed
+npm install -g base45
+
+# Decode the payload
+base45decode < payload.b45 > encrypted.pgp
+```
+
+**Option B: Using CyberChef (offline browser tool):**
+
+1. Download CyberChef HTML from <https://gchq.github.io/CyberChef/>
+2. Open it in an offline browser
+3. Input → Paste your Base45 payload
+4. Operation → `From Base45`
+5. Save output as `encrypted.pgp`
+
+**Option C: Manual verification (check CRC):**
+
+```bash
+# Verify CRC16 checksum matches
+# The CRC16-CCITT-FALSE checksum should match the value in the frame (58B5 in example)
+# If using the web app, this is automatically verified during decryption
+```
+
+***
+
+## 🔓 Step 3: Decrypt PGP Binary
+
+### Option A: PGP Private Key Decryption (PKESK)
+
+If the backup was encrypted with a PGP public key:
+
+```bash
+# Import your private key (if not already imported)
+gpg --import private-key.asc
+
+# List keys to verify fingerprint
+gpg --list-secret-keys --keyid-format LONG
+
+# Decrypt using your private key
+gpg --batch --yes --decrypt encrypted.pgp
+```
+
+**Expected JSON Output:**
+
+```json
+{"v":1,"t":"bip39","w":"abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about","l":"en","pp":0}
+```
+
+**If private key has a passphrase:**
+
+```bash
+gpg --batch --yes --passphrase "YOUR-PGP-KEY-PASSPHRASE" --decrypt encrypted.pgp
+```
+
+### Option B: Message Password Decryption (SKESK)
+
+If the backup was encrypted with a symmetric password:
+
+```bash
+gpg --batch --yes --passphrase "YOUR-MESSAGE-PASSWORD" --decrypt encrypted.pgp
+```
+
+**Expected JSON Output:**
+
+```json
+{"v":1,"t":"bip39","w":"your seed phrase words here","l":"en","pp":1}
+```
+
+***
+
+## 🔓 Step 4: Parse Decrypted Data
+
+The decrypted output is a JSON object with the following structure:
+
+```json
+{
+  "v": 1,                    // Version (always 1)
+  "t": "bip39",             // Type (always "bip39")
+  "w": "word1 word2 ...",   // BIP39 mnemonic words (lowercase, single spaces)
+  "l": "en",                // Language (always "en" for English)
+  "pp": 0                   // BIP39 passphrase flag: 0 = no passphrase, 1 = passphrase used
+}
+```
+
+**Extract the mnemonic:**
+
+```bash
+# After decryption, extract the 'w' field
+DECRYPTED='{"v":1,"t":"bip39","w":"abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about","l":"en","pp":0}'
+MNEMONIC=$(echo "$DECRYPTED" | grep -o '"w":"[^"]*"' | cut -d'"' -f4)
+echo "Mnemonic: $MNEMONIC"
+```
+
+***
+
+## 💰 Step 5: Wallet Recovery
+
+### BIP39 Passphrase Status
+
+Check the `pp` field in the decrypted JSON:
+
+- `"pp": 0` → No BIP39 passphrase was used during backup
+- `"pp": 1` → **BIP39 passphrase was used** (25th word/extra passphrase)
+
+### Recovery Instructions
+
+**Without BIP39 Passphrase (`pp": 0`):**
+
+```
+Seed Words: [extracted from 'w' field]
+BIP39 Passphrase: None required
+```
+
+**With BIP39 Passphrase (`pp": 1`):**
+
+```
+Seed Words: [extracted from 'w' field]
+BIP39 Passphrase: [Your original 25th word/extra passphrase]
+```
+
+**Wallet Recovery Steps:**
+
+1. **Hardware Wallets (Ledger/Trezor):**
+   - Start recovery process
+   - Enter 12/24 word mnemonic
+   - **If `pp": 1`:** Enable passphrase option and enter your BIP39 passphrase
+
+2. **Software Wallets (Electrum, MetaMask, etc.):**
+   - Create/restore wallet
+   - Enter mnemonic phrase
+   - **If `pp": 1`:** Look for "Advanced options" or "Passphrase" field
+
+3. **Bitcoin Core (using `hdseed`):**
+
+   ```bash
+   # Use the mnemonic with appropriate BIP39 passphrase
+   # Consult your wallet's specific recovery documentation
+   ```

+
+- Download Gpg4win from <https://www.gpg4win.org/>
+- Install and use Kleopatra or command-line gpg
+
+**Verify installation:**
+
+```bash
+gpg --version
+```
+
+***
+
+## 🔍 Troubleshooting
+
+| Error | Likely Cause | Solution |
+|-------|-------------|----------|
+| `gpg: decryption failed: No secret key` | Wrong PGP private key or key not imported | Import correct private key: `gpg --import private-key.asc` |
+| `gpg: BAD decrypt` | Wrong passphrase (key passphrase or message password) | Verify you're using the correct passphrase |
+| `base45decode: command not found` | base45 CLI tool not installed | Use CyberChef or install: `npm install -g base45` |
+| `gpg: no valid OpenPGP data found` | Invalid Base45 decoding or corrupted payload | Verify Base45 decoding step, check for scanning errors |
+| `gpg: CRC error` | Frame corrupted during scanning/printing | Rescan QR code or use backup copy |
+| `gpg: packet(3) too short` | Truncated PGP binary | Ensure complete frame was captured |
+| JSON parsing error after decryption | Output not valid JSON | Check if decryption succeeded, may need different passphrase |
+
+**Common Issues:**
+
+1. **Wrong encryption method:** Trying PGP decryption when symmetric password was used, or vice versa
+2. **BIP39 passphrase mismatch:** Forgetting the 25th word used during backup
+3. **Frame format errors:** Missing `SEEDPGP1:` prefix or incorrect colon separation
+
+***
+
+## 📦 Recovery Checklist
+
+```
+[ ] Airgapped computer prepared (offline, clean OS)
+[ ] GPG installed and verified
+[ ] Base45 decoder available (CLI tool or CyberChef)
+[ ] SEEDPGP1 frame extracted and verified
+[ ] Base45 payload decoded to PGP binary
+[ ] CRC16 checksum verified (optional but recommended)
+[ ] Correct decryption method identified (PGP key vs password)
+[ ] Private key imported (if PGP encryption)
+[ ] Decryption successful with valid JSON output
+[ ] Mnemonic extracted from 'w' field
+[ ] BIP39 passphrase status checked ('pp' field)
+[ ] Appropriate BIP39 passphrase ready (if 'pp': 1)
+[ ] Wallet recovery tool selected (hardware/software wallet)
+[ ] Test recovery on testnet/small amount first
+[ ] Browser/terminal history cleared after recovery
+[ ] Original backup securely stored or destroyed after successful recovery
+[ ] Funds moved to new addresses after recovery
+```
+
+***
+
+## ⚠️ Security Best Practices
+
+**Critical Security Measures:**
+
+1. **Always use airgapped computer** for recovery operations
+2. **Never type mnemonics or passwords on internet-connected devices**
+3. **Clear clipboard and terminal history** after recovery
+4. **Test with small amounts** before recovering significant funds
+5. **Move funds to new addresses** after successful recovery
+6. **Destroy recovery materials** or store them separately from private keys
+
+**Storage Recommendations:**
+
+- Print QR code on archival paper or metal
+- Store playbook separately from private keys/passphrases
+- Use multiple geographically distributed backups
+- Consider Shamir's Secret Sharing for critical components
+
+***
+
+## 🔄 Alternative Recovery Methods
+
+**Using the SeedPGP Web App (Online):**
+
+1. Open <https://seedpgp.com> (or local instance)
+2. Switch to "Restore" tab
+3. Scan QR code or paste SEEDPGP1 frame
+4. Provide private key or message password
+5. App handles Base45 decoding, CRC verification, and decryption automatically
+
+**Using Custom Script (Advanced):**
+
+```python
+# Example Python recovery script (conceptual)
+import base45
+import gnupg
+import json
+
+frame = "SEEDPGP1:0:58B5:2KO K0S-U. M:..."
+parts = frame.split(":", 3)
+crc_expected = parts[2]
+b45_payload = parts[3]
+
+# Decode Base45
+pgp_binary = base45.b45decode(b45_payload)
+
+# Decrypt with GPG
+gpg = gnupg.GPG()
+decrypted = gpg.decrypt(pgp_binary, passphrase="your-passphrase")
+
+# Parse JSON
+data = json.loads(str(decrypted))
+print(f"Mnemonic: {data['w']}")
+print(f"BIP39 Passphrase used: {'YES' if data['pp'] == 1 else 'NO'}")
+```
+

+
+## 📝 Technical Details
+
+**Encryption Algorithms:**
+
+- **PGP Encryption:** AES-256 (OpenPGP standard)
+- **Symmetric Encryption:** AES-256 with random session key
+- **CRC Algorithm:** CRC16-CCITT-FALSE (polynomial 0x1021)
+- **Encoding:** Base45 (RFC 9285)
+
+**JSON Schema:**
+
+```json
+{
+  "$schema": "http://json-schema.org/draft-07/schema#",
+  "type": "object",
+  "required": ["v", "t", "w", "l", "pp"],
+  "properties": {
+    "v": {
+      "type": "integer",
+      "const": 1,
+      "description": "Protocol version"
+    },
+    "t": {
+      "type": "string",
+      "const": "bip39",
+      "description": "Data type (BIP39 mnemonic)"
+    },
+    "w": {
+      "type": "string",
+      "pattern": "^[a-z]+( [a-z]+){11,23}$",
+      "description": "BIP39 mnemonic words (lowercase, space-separated)"
+    },
+    "l": {
+      "type": "string",
+      "const": "en",
+      "description": "Language (English)"

+      "type": "array",
+      "items": {"type": "string"},
+      "description": "Optional: Recipient key fingerprints"
+    }
+  }
+}
+```
+
+**Frame Validation Rules:**
+
+1. Must start with `SEEDPGP1:`
+2. Frame version must be `0` (single frame)
+3. CRC16 must be 4 hex characters `[0-9A-F]{4}`
+4. Base45 payload must use valid Base45 alphabet
+5. Decoded PGP binary must pass CRC16 verification

+ *
+ * @summary
+ * A direct and 100% logic-compliant port of the 'dice_mix_interactive.py'
+ * Python script to TypeScript for use in browser environments. This module
+ * implements XOR-based seed blending and HKDF-SHA256 enhancement with dice
+ * rolls using the Web Crypto API.
+ *
+ * @description
+ * The process involves two stages:
+ * 1.  **Mnemonic Blending**: Multiple BIP39 mnemonics are converted to their
+ *     raw entropy and commutatively blended using a bitwise XOR operation.
+ * 2.  **Dice Mixing**: The blended entropy is combined with entropy from a
+ *     long string of physical dice rolls. The result is processed through
+ *     HKDF-SHA256 to produce a final, cryptographically-strong mnemonic.
+ *
+ * This implementation strictly follows the Python script's logic, including
+ * checksum validation, bitwise operations, and cryptographic constructions,
+ * to ensure verifiable, deterministic outputs that match the reference script.
