REQ-EL-007 — Test Limit Derivation Documented

Every test case that defines numeric measurement limits (low_limit, high_limit, nominal, tolerancePct) shall have a documented derivation explaining how those limits were chosen.

For each test case with numeric limits, evidence of derivation exists — passCriterion references the component values and tolerances in the measurement path, OR a linked please_decision documents the corner math, OR the implementing Maestro YAML carries a Limit derivation comment block citing such a decision.
