Portability scoring rubric

Dimension	Score 0	Score 1	Score 2
semantic portability	unclear semantics	partially mapped	invariant preserved
compiler portability	manual rewrite	adapter needed	automated lowering
evidence portability	provider-specific only	partial mapping	canonical package
governance portability	manual exception	partial policy mapping	policy portable
economic portability	uneconomic	uncertain	viable
