- Slash commands (`/h1`, `/todo`, `/callout`, `/code`, `/math`, `/database`, `/table`).
- Custom callout iconography with emoji picker and brand image logo upload.
- Full Markdown and KaTeX mathematical equation support.
- Bidirectional wiki-linking (`[[Page Title]]`) with real-time backlink indexing.

### 2. Internal Link Health & Topic Cluster Engine
- Deterministic topological graph resolver analyzing internal linking structure.
- Automatic detection of orphan pages (pages with 0 inbound references).
- Pillar-to-cluster topic hierarchy visualization and crawlability scoring.
- Highlighting of broken wiki-links and dead reference paths.

### 3. Interactive D3 Visual Knowledge Graph Studio
- Live physics-based force-directed 2D/3D graph visualization of documents.
- Node centrality metrics, connection degree filtering, and cluster isolation.
- Fast navigation by clicking graph nodes to jump directly into the document editor.

### 4. Multidimensional Relational Databases
- Custom database schemas supporting Table, Kanban Board, and Editorial Calendar views.
- Field types: Text, Number, Select, Multi-Select, Date, Person, Formula, Status, Checkbox.
- Cross-database relational links and rollup rollouts.

### 5. Multi-User Authentication & Account Management System
- Complete user registration with email verification, password strength enforcement, and terms acceptance.
- Secure sign-in with PBKDF2 cryptographic hashing and 30-day session persistence.
- Single-use, expiring password recovery and reset token workflows.
- User profile management (name, job title, avatar personalization).
- Password change with current-credential re-authentication.
- Permanent Account Deletion with identity re-verification, typed phrase confirmation, and complete database teardown.
- Instant Guest Mode: Direct one-click exploration without requiring login or passwords.

### 6. Local-First Security & Privacy Guarantees
- Local-first encrypted browser persistence with deterministic state synchronization.
- Granular per-page privacy controls (Private by default, Public publish toggle).
- Zero third-party telemetry, ads, or tracking scripts.
