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 configures a logr.Logger for testing.TB with verbosity filtering
  2. logr.FromContextOrDiscard returns context logger if present or safe non-nil discard logger if missing
  3. logr.New constructs a Logger from a custom LogSink interface implementation
  4. logger.WithCallDepth offsets call stack frames for helper functions
  5. funcr.Options with RenderBuiltinsHook and RenderValuesHook transforms structured key-value pairs
