Rotifer v0.6.5: Cross-Binding Proof — How We Validated IR Portability Without Deploying to a Blockchain

Rotifer v0.6.5 validates IR (Intermediate Representation) portability across different binding environments without requiring actual blockchain deployment, using a Web3MockBinding with different resource constraints instead. The release introduces the RotiferBinding trait for binding abstraction and a capability negotiation protocol, delivering 9 cross-binding interoperability tests that produced 7 recommendations for IR 0.2.0 spec evolution.
