Marius CiepluchandClaude Fable 5.1 4d56b3c76e feat(corpus-seeded-mechanisms): structural shapes derived from labeled pairs
Task 1.1 (Req 2.1-2.4). Spec approved by the maintainer in session.

- semantic/variants.py: Shape (language, sink trailing name, arity,
  source positions and kinds, closed guard kind, mechanism id) with a
  stable text-free key; derive_shape finds the labeled sink call site in
  the vulnerable FileIR, traces argument identifiers through binds to a
  fact source, a parameter or a container read, and classifies the guard
  the fixed side added from the labeled function's added statements
  against a closed set (none when unknown). No path, line or literal
  enters a shape; a constant-only call teaches nothing.
