construct-validity-envelope

Purpose

Synthesize multi-axis breakpoints into a multidimensional statement of where a claim or method remains valid.

Input contract

required: [claim_or_method, axis_results, validity_criteria]
optional: [boundary_interactions, uncertainty_model, extrapolation_policy]
constraints: [each boundary is tied to an axis result and evidence]

Procedure

1. Align axis scales, directions, and validity labels.
2. Combine breakpoint regions and inspect interaction effects.
3. Mark supported, uncertain, and invalid regions.
4. Emit the envelope with extrapolation warnings and monitoring observables.

Output contract

produces: [validity_envelope, boundary_conditions, uncertain_regions, monitoring_observables]
delta_fields: [findings, uncertainties, open_questions]
