FLM untrained anatomical selections and artificial rewiring controls

See source-manifest.json and rewiring-manifest.json for all identities,
constraints, seeds, diagnostics and retained failures. No trained weights
or tokenizer are included. Rewired edges are artificial: transferred
contacts are input-slot magnitudes, not measurements of those body pairs.
