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. Returning undefined from a custom renderer method produces an empty string rather than delegating to the default renderer, which requires returning explicit boolean false.
  2. Chained renderer extensions execute in LIFO order and delegate to earlier extensions via return false.
  3. marked.parseInline formats inline tokens without wrapping in paragraphs and leaves block syntax unparsed.
  4. Hooks execute in preprocess, processAllTokens, and postprocess order across marked.parse.
