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. certifi.where returns an existing, absolute, non-empty filesystem path to the CA bundle file
  2. certifi.contents returns the full PEM certificate bundle text containing valid BEGIN CERTIFICATE and END CERTIFICATE blocks
  3. ssl.create_default_context with cafile=certifi.where() produces an SSLContext with CERT_REQUIRED, check_hostname enabled, and non-empty CA certificates
  4. ssl.SSLContext.load_verify_locations with cadata=certifi.contents() successfully loads root certificates directly into an SSLContext without file I/O
  5. certifi.__version__ is a valid non-empty package version string
