REQ-TS-006 — Test Limit Derivation Documented

Every test step in this test system shall have its pass/fail limits derived from the documented tolerance stack of all components in the measurement path (references, dividers, resistors, ADCs, drivers, wiring).

For each test step with numeric limits, evidence of derivation exists — passCriterion enumerates the relevant components and their tolerances, OR a linked please_decision documents the corner math, OR the implementing Maestro YAML carries a Limit derivation comment block.
