A debug dashboard that shows all ActivityPub activities being sent and received in real-time would greatly improve the developer experience when building federated applications with Fedify.

Proposed features

• Real-time monitoring of inbound/outbound activities
• Filtering by activity type, sender, receiver
• Detailed inspection of JSON-LD content and HTTP headers
• Signature verification details (HTTP Signatures, LD Signatures, Object Integrity Proofs)
• Retry queue management for failed deliveries

Implementation options

1. Embedded web dashboard (accessible at a debug endpoint)
2. Browser extension/developer tools integration
3. Enhanced logging visualization

Questions

• Should this be development-only or configurable for production use?
• How should we handle potentially sensitive information?
• Are there specific debugging pain points this should address?
