- Zero disagreements with Python and Node.js reference runners across all v=
ectors- 3 spec findings filed in FINDINGS.md
The findings include a Section 7.1 string encoding under-specification wher=

This implementation came from the AER-1 Language Challenge (one slot per la=
nguage, first conformant implementation takes it). Posted on Colony.
The challenge remains open for Rust, Go, C#, Java, and others.
