Crate saorsa_gossip_pubsub 

Plumtree-based pub/sub dissemination

Implements:

• EAGER push along spanning tree
• IHAVE lazy digests to non-tree links
• IWANT pull on demand
• PRUNE/GRAFT for tree optimization
• Anti-entropy reconciliation (placeholder for future)

Architecture

Each topic maintains two sets of peers:

• Eager peers (tree): Forward full messages immediately
• Lazy peers (gossip): Send only message IDs (IHAVE)

The tree self-optimizes via duplicate detection (PRUNE) and pull requests (GRAFT).
