docs(v5): point the V9 gate at the cross-engine correctness strategy#42
Merged
Conversation
The V9 cross-validation gate is Tier 2 of the tiered correctness model in TemporalHazard/inst/dev/CORRECTNESS-STRATEGY.md (R-only invariants -> cross-engine differential gate on a shared Parquet contract -> frozen golden anchors). Add a pointer so the v5 audience finds it, and note the reference-authority principle (correct = math + agree-where-right, not match-SAS) that bounds V9's scope.

Surfaces the cross-engine correctness strategy (lives in
TemporalHazard/inst/dev/CORRECTNESS-STRATEGY.md) for the v5/cross-engine audience.Adds a pointer next to the V9 cross-validation gate in the v5 design spec: V9 is Tier 2 of the tiered model (Tier 1 = R-only invariants, shipped; Tier 2 = cross-engine differential gate over a shared structured/Parquet contract with one generic comparator at a statistical tolerance; Tier 3 = a frozen golden-anchor set). Records the reference-authority principle — correct = satisfies the math, and agrees with the other engine where it's right, not matches SAS — which bounds V9's scope (diff structured outputs within tolerance; don't chase SAS print conventions).
