🎉 Your vault is ready to use RIGHT NOW!
cd /Users/air/Lexecon
./launch_vault.shThis will:
- Start a local web server
- Open your browser automatically
- Show keyboard shortcuts
cd /Users/air/Lexecon
python3 -m http.server 8001Then open: http://localhost:8001/vault_minimal.html
Or simply open vault_minimal.html in your browser directly.
- Open the vault (see above)
- Click "New Note" or press
Ctrl+N - Add a title like: "Engineering Vault Setup - Day 1"
- Write your first entry:
# Engineering Vault Setup
## What I Built Today
Created a personal engineer's vault using my own Lexecon infrastructure.
## Key Features Implemented
- [x] Cryptographic audit trail (simulated)
- [x] Local storage for immediate privacy
- [x] Markdown support for rich notes
- [x] Export functionality with "signatures"
## Technical Notes
- Uses browser localStorage (temporary for MVP)
- Next step: SQLite backend with encryption
- Eventually: Ed25519 signatures like Lexecon proper
## IP Protection Notes
This vault entry itself demonstrates:
1. Timestamp: 2026-01-11
2. Version control tracking
3. Cryptographic hashing (simulated)
4. Future legal defensibility

Current (Minimal Version):
- Stored in your browser's localStorage
- Key:
engineer_vault_notes - Limitation: Only accessible in this browser
This Week (Upgrade Plan):
- Move to:
/Users/air/Lexecon/personal_vault.db - Encrypted SQLite database
- Works across browsers & machines
- Client-side encryption (you hold the key)
- Backup your work before upgrade
- Legal proof of invention timeline
- Portability if you switch browsers
- Cryptographic evidence (simulated for now, real soon)
- Open vault
- Click "Export All" button
- Or: Press
Ctrl+E - File saves to:

-
Initialize encrypted database:
cd /Users/air/Lexecon python3 -c " import sqlite3 conn = sqlite3.connect('personal_vault.db') cursor = conn.cursor() cursor.execute('CREATE TABLE IF NOT EXISTS notes (id TEXT PRIMARY KEY, title TEXT, content TEXT, encrypted BLOB)') conn.commit() conn.close() print('✓ Vault database created') "
-
Migrate from localStorage to SQLite
- Import existing notes
- Encrypt with master password
- Verify integrity
-
Update vault to use new backend
- Same UI, persistent storage
- Works across all browsers
- Encrypted at rest
-
Add Ed25519 signing
from lexecon.identity.signing import NodeIdentity identity = NodeIdentity.load_or_create() signature = identity.sign_message(note_content)
-
Hash-chained ledger
- Every edit linked to previous
- Tamper-evident
- Can verify entire chain
-
Integrity verification tool
vault verify # Output: Chain intact from genesis to head ✓
- Code snippets manager
- Project kanban boards
- IP asset registry
- Search & export enhancements
- CLI tool for quick notes
- Audit Trail: Every action logged with timestamp
- Version Control: Track all changes
- Simulated Hashing: SHA-256 style fingerprints
- "Signatures": Placeholder for real Ed25519
- Export Protection: JSON with metadata
- Ed25519 Signatures: Cryptographically signed entries
- Hash Chain: Tamper-evident ledger
- PBKDF2 Keys: Password-derived encryption keys (1M iterations)

When you have an idea you might patent:
- Write detailed note in your vault
- Tag it:
#patent-idea #invention - Export immediately (creates timestamp)
- Store export securely (legal evidence)
Result: Cryptographic proof of invention date
For confidential business information:
- Set privacy level: "strictly-confidential"
- Document access controls in vault
- Log all views (audit trail)
- Demonstrates "reasonable efforts" to protect
Result: Stronger trade secret protection in court
If you're building IP outside your day job:
- Use separate vault (not employer's systems)
- Clear timestamps showing personal time
- Detailed notes of your own work
- No employer resources used
Result: Clear ownership, defensible timeline

- Where to store master password?
- Backup strategy?
Q: Where's my data stored?
A: Right now: browser localStorage. This week: /Users/air/Lexecon/personal_vault.db
Q: Is it really secure? A: Today is MVP with simulated crypto. Real encryption & signatures coming this week.
Q: Can I lose my data? A: Yes! LocalStorage can be cleared. Export your data daily until SQLite upgrade.
Q: How do I prove I invented something? A: 1) Write detailed note, 2) Export immediately, 3) Store securely, 4) Timestamps + hashes = evidence
Q: Can I share with my team? A: Not yet. Coming: team vaults with shared encryption keys.
