Pins Heimdall's rule: a write_admitted messageId needs a Unicode letter or number and no Default_Ignorable_Code_Point, compared raw. Shared vectors plus a runner test in TS, Python, Kotlin, C# and Rust. No decoder changed; the refuse vectors fail. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
