apply-veto-filter

Purpose

Eliminate alternatives that violate any declared hard threshold and expose the exact veto condition for each removal.

Input contract

required: [alternatives, hard_constraints, measured_values]
optional: [constraint_priorities, missing_value_policy]
constraints: [each alternative is tested against every hard constraint; missing measurements cannot silently pass]

Procedure

1. Bind each hard constraint to its direction, threshold, unit, and evidence source.
2. Check every alternative against every constraint and record pass, fail, or unknown per cell.
3. Veto an alternative when any hard constraint fails; keep unknowns separate from passes.
4. Return survivors, vetoed alternatives, violated constraints, and unresolved checks.

Output contract

produces: [survivor_set, veto_log, unresolved_checks]
delta_fields: [findings, evidence_updates, uncertainties, decisions]
