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. assert resolve matches root path and extracts empty kwargs
  2. assert int converter matches integer segment, converts parameter to int, and rejects non-integer strings with Resolver404
  3. assert slug and str converters match formatted segments and extract named string kwargs
  4. assert reverse reconstructs route URLs from route names and keyword parameters, and raises NoReverseMatch on invalid arguments
  5. assert test Client successfully dispatches requests to views mapped via path and returns 404 for unmatched paths
