Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert RegisterCollationUtf8 registers custom collation sequence with database/sql sqlite driver
  2. assert table column definition with custom collation applies reverse case-insensitive ordering
  3. assert column collation affects WHERE equality matching
  4. assert ORDER BY with explicit COLLATE length_first sorts by string length then lexicographically
  5. assert WHERE comparison with COLLATE length_first filters rows based on custom collation logic
