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. testr.NewWithInterface connects logr.Logger to custom TestingT test runners with verbosity filtering
  2. testr.NewWithOptions configures timestamp rendering and testing output for test logging
  3. logr.Logger.WithCallDepth adjusts caller frame resolution for helper functions with CallDepthLogSink
  4. funcr.Options.LogCaller and LogCallerFunc capture source location and function name metadata
  5. logr.FromContextOrDiscard safely extracts logger from context or returns zero discard logger without error
