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 filesystem path to the CA bundle file
  2. certifi.contents returns the non-empty PEM certificate bundle containing BEGIN CERTIFICATE markers
  3. certifi.__main__ CLI execution prints the certificate bundle path by default
  4. certifi.__main__ CLI execution with -c flag prints the certificate bundle contents
  5. ssl.create_default_context using certifi.where() creates a client SSLContext enforcing certificate verification
