Bridge Review: Sensor Series, Outliers, and Evidence

This route no longer serves as a full Java arrays lesson. Array declaration, indexing, .length, and traversal belong in java-programming.

The bridge problem is the evidence carried by a short sensor series:

0.41, 0.42, 3.70, 0.40

Your job is to preserve the original order, classify each reading against an explicit contract, keep rejected values visible, and compare that local Java evidence with the ROS topic/interface evidence available for the same sensing domain.

The key distinction is:

Java collection/array state
!= ROS topic history
!= physical sensor truth

A normal average does not erase an outlier. A ROS topic type does not prove the Java array came from that topic. A supplied message does not prove a physical sensor was accurate.

Required artifact

Produce a Range Series Audit with the original series, accepted/rejected classification, one aggregate, the preserved outlier, the related ROS interface evidence, and one hypothesis that remains unconfirmed.

If indexing or array mechanics are the blocker, reactivate that prerequisite in java-programming rather than expanding this bridge route.
