 ## Executive Summary
 
-NATSBridge is a cross-platform, bi-directional data bridge that enables seamless communication between **Julia**, **JavaScript**, **Python**, and **MicroPython** applications using NATS as the message bus. The system implements the **Claim-Check pattern** for efficient handling of large payloads (>1MB) by uploading them to an HTTP file server instead of sending raw binary data over NATS.

 1. **Cross-Platform Interoperability**: Enable seamless data exchange between Julia, JavaScript, Python, and MicroPython applications without platform-specific barriers.
 
 2. **Efficient Large Payload Handling**: Implement intelligent transport selection based on payload size:
-   - **Direct Transport**: Small payloads (<1MB) sent directly via NATS
-   - **Link Transport**: Large payloads (≥1MB) uploaded to HTTP file server, URL sent via NATS
+   - **Direct Transport**: Small payloads (<0.5MB) sent directly via NATS
+   - **Link Transport**: Large payloads (≥0.5MB) uploaded to HTTP file server, URL sent via NATS
 
 3. **Unified API Across Platforms**: Provide consistent `smartsend()` and `smartreceive()` functions across all supported platforms while maintaining idiomatic implementations.
