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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. Collected::to_bytes consumes Collected and returns only concatenated data frames, silently dropping trailers unless collected.trailers() is inspected first
  2. Frame::into_data returns Err(Frame) on trailer frames instead of returning data or empty bytes
  3. Frame::map_data transforms data frame payloads while leaving trailer frames unmodified
  4. Limited enforces byte limits against data frames while ignoring trailer frame sizes
  5. Limited returns LengthLimitError wrapped in BoxError when data bytes exceed the limit
