1. Red Conformance

• 1.1 Add fixed valid and invalid terminal-receipt vectors and prove Python, Go, Rust, and Swift reject the required valid vector
• 1.2 Add a Data Plane independent-client regression that consumes the Protocol fixed vector rather than the production encoder

2. Contract Repair

• 2.1 Update the VGF1 grammar and Protocol validator sources for the exact empty client-direction type 0x03 receipt
• 2.2 Regenerate bindings normally and prove deterministic generation has no drift
• 2.3 Run complete Protocol verification and strict OpenSpec validation

3. Immutable Release

• 3.1 Verify the next version is unused locally and remotely, publish one immutable annotated tag, and verify its object and peeled commit
• 3.2 Resolve the version from separate empty caches and pin exact fetched checksums in Data Plane and Connection Server
