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. id.MarshalJSON serializes xid.ID as a 20-character base32 quoted JSON string
  2. id.UnmarshalJSON parses a valid JSON string into xid.ID and handles null as NilID
  3. id.Value returns the 20-character string representation implementing database/sql driver.Valuer
  4. id.Scan unmarshals string or byte representations into xid.ID and handles nil implementing sql.Scanner
  5. id.Compare returns -1, 0, or 1 based on lexicographical ordering of identifiers
  6. xid.Sort sorts a slice of xid.ID identifiers in ascending order
