Follow-ups from the Part-1 (engine capability) review. Split rationale + deferred direction: decision-3 (opaque-transform split).
- #1 Out-of-projection transformer calls: build-time guard/consistent resolve so Rust and DF agree
- #2 Add a single-field 1-in/1-out transformer differential parity case (oracle y[:,i] assumes 2-D)
- #3 Enforce or reconcile out_schema vs the transform natural output dtype
