v3.13.0

Summary

Fewer placeholder findings on null objects, base-class defaults and framework
hooks that declare their defaults, and a few more stubs caught.

What moves when you upgrade

• Declared defaults are not stubs. A class named as a null object or a base
  (NullRenderer, BaseFeature), a constant answer in a subclass of such a
  base, an empty @click.group() body, and raise NotImplementedError where a
  base or sibling methods fix the interface no longer produce placeholder
  findings. A log line in front, a constructed success answer or a docstring
  that says "placeholder" keeps the finding.
• A declared no-op is not a stub. An empty body whose docstring summary
  sentence says no-op or does nothing, in a method whose signature a base fixes
  or a callback registered by value, is no longer reported. The words alone
  never exempt: a denial or demand in that sentence, "placeholder", "for now",
  a declaration only in a later sentence, or a function with no base or
  registration keeps the finding.
• More stubs are caught. Print or log lines before raise NotImplementedError, a class built from literals with a success mark, a
  swallowed failure followed by a constant the comment calls invented, a
  documented parameter never read, and a function that only builds values it
  throws away.
• Scores of files with declared defaults go down; the scoring formula, bands
  and JSON keys are unchanged. Analysis cache analysis-cache-v37.
• The VS Code extension carries the core's version again (3.13.0; it had
  stayed at 3.8.9). Its views read the same JSON fields as before.

Known limitations

• A base no-op overridden in another file, a no-op hook whose reason is only
  in its docstring, a null object not named as one, and a helper returning a
  fixed symbol can still be reported: the evidence is not in one file or name.
• An ignored input whose call site is in another module, and a hollow result
  only the meaning of names reveals (a "mail sent" with no recipient), are not
  found.
• An empty pass body under a registering decorator is treated as declared
  (@register(...) def load_checkpoint(...): pass is not reported).
• ignored_parameter can report parameters kept by a signature that siblings,
  a framework callback or a base interface fix.
• return_constant_stub can report functions whose name or docstring says the
  constant is the answer (*_prompt, *_message, a tool acknowledgement).
• Interface no-ops are reported when their base is outside the module or their
  reason is only in a comment, including a @singledispatch default that
  raises NotImplementedError.
