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. pgx.ParseConfig parses PostgreSQL connection URI and extracts host, port, database, user, password, and runtime parameters
  2. pgx.ParseConfig parses key-value connection string and sets connect timeout
  3. sample.ConfigureConnection parses DSN and sets application_name and connect timeout
  4. sample.ValidateConfig validates presence of required database connection fields
  5. pgx.ParseConfig returns error for invalid connection strings
