Integrate variants by extending the shared core behind explicit gates

Summary#

Problem#

A new model or feature variant shares most of an existing implementation, but a few new conditions or behaviors tempt a forked subclass or duplicated code path.

Solution#

Keep one core implementation and add the variant behavior behind explicit flags, condition tensors, or capability checks. Reuse the existing structure when weights or architecture are materially the same, so legacy paths remain unchanged and only the new inputs activate the new logic.

Failure Modes#

Gating is too broad and changes legacy behavior unintentionally.
Variant-specific assumptions leak into the common path and create hard-to-debug regressions.
Teams create parallel subclasses for near-identical models, causing drift and duplicate fixes.
