1. Red conformance

• 1.1 Add fixed datagram-v2 and capability vectors that fail current Python, Go, Rust, and Swift validators
• 1.2 Prove unknown version, malformed length, invalid fragment, and oversized complete-unit cases remain rejected

2. Contract implementation

• 2.1 Add the versioned datagram-v2 frame grammar and registered framing values
• 2.2 Update generator/native validators and regenerate Go, Rust, and Swift bindings normally

3. Verification

• 3.1 Run focused cross-language conformance and strict OpenSpec validation
• 3.2 Run complete make verify and prove a second generation has no drift

4. Immutable boundary

• 4.1 Publish one new never-reused immutable Protocol version and resolve it from empty consumer caches
