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. sqlite.RegisterCollationUtf8 registers a custom UTF-8 collation function with the sqlite driver
  2. sqlite.MustRegisterCollationUtf8 registers a custom collation sequence accessible across all subsequently opened database connections
  3. Table column definitions specifying COLLATE use the custom collation for default ordering and WHERE filtering
  4. SELECT queries with explicit COLLATE clauses in ORDER BY evaluate ordering according to the registered collation function
  5. Custom collation correctly handles Unicode multi-byte strings and empty strings with consistent three-way comparison semantics
