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. sqlite.RegisterCollationUtf8 registers a custom UTF-8 string collation function with the sqlite driver
  2. Executing SELECT queries with ORDER BY COLLATE sorts text values using the custom Go collation logic
  3. Custom string collations function correctly with custom sorting orders like length-based and reverse ordering
  4. Creating an index with COLLATE custom_collation enforces custom collation ordering on table indexing and queries
