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.QueryTracer interface defines TraceQueryStart and TraceQueryEnd hooks for query execution observability
  2. pgx.TraceQueryStartData conveys SQL query string and arguments slice at query start
  3. pgx.TraceQueryEndData conveys pgconn.CommandTag and error at query completion
  4. pgx.ConnConfig Tracer field accepts a pgx.QueryTracer implementation
  5. query tracer context propagation allows passing trace state from TraceQueryStart to TraceQueryEnd
  6. sample helpers provide recording and filtering query tracer implementations
