Sample
b4a buffer allocation, encoding conversion, and slicing

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 b4a.alloc allocates zero-filled buffer of requested byte length
- assert b4a.from creates buffer from string with utf8, hex, and base64 encodings
- assert b4a.toString decodes buffer into utf8, hex, and base64 strings
- assert b4a.concat joins multiple buffer chunks into a single contiguous buffer
