🔦 Lumen v2.2.3 — Release Notes

Lumen has evolved from a standalone journaling engine into a multi-user productivity platform. This release introduces secure multi-author profiles, a powerful terminal interface, and a significant expansion of the Stoic import engine.

👥 Multi-User & Permission System

• Role-Based Access Control: Introduced a native permission system with Admin and Member roles.
  • The first user registered in a vault is automatically assigned the Admin role.
  • Members have full access to their own journals but are restricted from vault management tasks.
• User Profiles: Support for multiple authors within a single vault. Select your profile at login or switch securely within an active session.
• Secure Switching: User switching and registration are now protected by the vault's master password, even if the application is already unlocked.
• Auto-Login: Automatically "logs in" the selected user profile upon master unlock for a seamless entry experience.

💻 Lumen TUI (Terminal Interface)

• CLI Client: Introducing lumen-cli, a native terminal companion for headless access to your vault.
• Search & View: List, search (metadata-based), and view decrypted entries directly from your terminal.
• Streak Tracking: Quickly check your journaling consistency with the lumen streak command.
• Secure Decryption: Full Argon2/AES-GCM decryption support within the CLI (password-protected).

📥 Enhanced Stoic Importer

• Routine Support: The importer now captures the bulk of Stoic data stored in routines.json, including Morning and Evening reflections.
• Intelligent Mapping: Automated mapping of over 4,000+ Stoic "Answers" to their respective routines and journal entries.
• Author Mapping: Choose which specific Lumen user profile should own the imported data.
• Visual Feedback: Real-time progress bars for large-scale data imports.

🏛️ Storage & Architecture

• SQLite Migration: Fully transitioned from bincode serialization to a robust SQLite backend for improved performance and atomicity.
• FTS5 Search: Integrated SQLite Full-Text Search (FTS5) for blazing-fast indexing of entry metadata and plaintext titles.
• Encrypted Assets: A new binary storage system for attachments (images, audio) linked securely to journal entries.

🎨 UI & UX Refinements

• Modern Typography: Switched to the Geist font family for a cleaner, high-contrast reading experience.
• Global Progress Bars: Added LinearProgressIndicator to all long-running operations (Sync, Save, Search, Decrypt).
• Localization: Full support for English, Spanish, and French via ARB files.
• Identity Badges: New sidebar indicators showing the current logged-in author and active vault.

🛡️ Security & Testing

• Property-Based Testing: Integrated the proptest framework to verify encryption idempotency across thousands of random edge cases.
• Reproducible Builds: All platform binaries are now compiled using --locked dependencies to ensure supply-chain security.
