Output Hub Node: Central Aggregation, Reverse Attribution & Batch Execution
The master terminal for prompt assembly, live Markdown synthesis, reverse origin tracking, and deterministic batch compilation.
# Output Hub Node
The **Output Hub Node** serves as the central real-time aggregation terminal and compilation engine for your visual workspace. It merges upstream prompt cards, tables, documents, and AI agent outputs into a unified final document stream.

## 1. Visual Anatomy
- **Header Bar**: Displays `Output Hub`, `☆ Set Primary` (or `★ Primary`) status pill, and collapse chevron.
- **Green Output Port (`OUT`)**: High-speed green circular handle (`#5ED368`) on the right border. Connect directly into Document Exporter nodes.
- **Dynamic Input Slots (`● IN`)**: Left-edge handles receiving incoming noodles in spatial/connection order.
- **`OUTPUT PROMPT` Window**: Inset dark terminal with 1-click Copy (`⧉`) and Full-Screen Expand (`⤢`).

## 2. Reverse Source Attribution & In-Place Editing
While viewing the compiled document in the expanded Output Hub modal:
- **Hover Attribution**: Hovering over any paragraph highlights it with an accent underline and displays the exact source node title, color swatch, and breadcrumb path.
- **Alt + Click In-Place Editing**: Press **`Alt + Click`** on any text block to immediately open the full-screen TipTap editor for that upstream source node. Your edits recompile and reflect in the Output Hub the instant you press `Escape`.
- **Canvas Camera Glide (`🎯 Locate on Canvas`)**: Automatically centers the canvas viewport directly on the origin node.

## 3. Deterministic Batch Compiler Engine
When a Table Node is connected upstream, the Output Hub becomes an automated batch document generator:
- **Batch Pre-Flight Audit**: Scans table rows, resolves template tokens, and checks character quotas before execution.
- **`⚡ Run Batch (N rows)`**: Generates individualized outputs across all dataset rows with progress tracking.
- **Safety Interlocks**: If an active AI Agent node is in the graph, batch generation is safely gated with clear guidance.
