Feature Specification: Rich-Text Authoring

1. Overview & Vision

The Rich-Text Authoring feature is the core creative engine of the Document module. It provides a professional, "What-You-See-Is-What-You-Get" (WYSIWYG) editing experience that allows users to create high-quality internal documentation, policies, and reports directly within the VENI-AI platform.

2. Personas & Stakeholders

Persona	Goal
Author	Create and format structured documents easily.
Reviewer	Read and comment on document content during the approval cycle.
Knowledge Admin	Maintain standard styles and formatting across the org.

3. User Stories

• As an author, I want to use Markdown shortcuts (like # for H1) so I can write without taking my hands off the keyboard.
• As an author, I want to insert tables and code blocks to document technical requirements.
• As an author, I want my work to be auto-saved every few seconds so I don't lose progress.

4. Functional Requirements (FR)

• REQ-ED-001: TipTap-based rich-text editing (Bold, Italic, Lists, H1-H3).
• REQ-ED-002: Support for advanced nodes (Tables, Code Blocks, Task Lists).
• REQ-ED-003: Markdown shortcut support for common formatting.
• REQ-ED-004: Automated background saving (every 30 seconds).

5. Non-Functional Requirements (NFR)

• Performance: Editor initialization < 500ms.
• Reliability: Zero data loss via local storage buffering (planned).

6. Business Logic & Rules

• Schema Validation: Content must strictly follow the TipTap JSON schema.
• Locking: Documents are read-only when in the "In Review" or "Published" state.
• Autosave Logic: Only triggers if changes are detected since the last save.

7. User Interface (UI/UX)

• Floating Toolbar: Context-sensitive formatting options (appears on selection).
• Sticky Menu: Top-bar with permanent action icons (Bold, Link, etc.).
• Distraction-free Mode: Option to hide sidebars for focused writing.

8. Information Architecture

• Primary view for docs.venizia.ai/edit/:id.
• Side-panel for "Outline" (Auto-generated from H1-H3 tags).

9. Data Model & Persistence

• Table: document_versions.
• Field: content (jsonb).
• Format: TipTap/Prosemirror JSON structure.

10. API & Service Layer

• PUT /documents/:id (Saves a new draft version).
• GET /templates/:id (Load initial content).

11. Integration Patterns

• TipTap Extensions: Custom extensions for platform links (e.g., linking to a Drive file).

12. Security & Permissions

• RBAC: documents:write required to access the editor.
• Content Security: Sanitization of all HTML/JSON before persistence.

13. Error Handling & Resilience

• Sync Conflict: Alert the user if a newer version exists on the server.
• Network Error: Notification when auto-save fails.

14. Performance & Scalability

• Efficient JSON serialization/deserialization.
• Support for documents up to 100,000 characters without lag.

15. Globalization & i18n

• Multi-language UI for the editor toolbar.
• Support for RTL (Right-to-Left) languages (planned for v2).

16. Accessibility (a11y)

• Standard keyboard shortcuts (Ctrl+B, Ctrl+I).
• Screen reader support for the document outline.

17. Observability & Analytics

• Tracking of "Time Spent Editing" per document.
• Analytics on "Most Used Formatting Tools".

18. Testing & Quality

• Integration tests for JSON schema validation.
• Cypress E2E tests for the auto-save sequence.

19. Constraints & Assumptions

• Assumes users have a modern browser with JavaScript enabled.

20. Future Enhancements

• Real-time collaborative editing (Yjs/Websocket integration).
• AI Writing Assistant (Integrate with AI module for rewording/summarizing).
