Sample
encode and decode 32-bit and 64-bit floating point numbers using IEEE 754

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- assert encodeF32 returns a 4-byte little-endian array and decodeF32 round-trips single-precision floats
- assert encodeF32 and decodeF32 handle special float values including Infinity, -Infinity, and NaN
- assert encodeF64 returns an 8-byte little-endian array and decodeF64 round-trips double-precision floats
- assert encodeF64 and decodeF64 handle special double values including Infinity, -Infinity, and NaN
- assert decodeF32 and decodeF64 accept Uint8Array byte buffers as input
