Decision: Harden NRMSE and Use Metric Profiles in RotatingMachine

Date: 2026-02-24
Scope: nodes/generalFunctions/src/nrmse/*, nodes/rotatingMachine/src/specificClass.js

Context

Drift analytics were previously single-path and flow-focused with weak input safeguards in NRMSE.
Requirement: make NRMSE architecturally robust and apply it across multiple measurements in rotatingMachine.

Decision

Adopt a metric-profile drift architecture:

Harden generalFunctions/nrmse with:

strict validation for malformed inputs
timestamp-aware alignment support
per-metric state
configurable rolling window and EWMA long-term trend
point-based API (assessPoint) while retaining legacy calls

Rewire rotatingMachine to consume NRMSE per metric:

flow model drift
power model drift
pressure-quality drift as node-specific plausibility/redundancy assessment

Expose drift and confidence outputs per metric in node output payload.

Consequences

Drift computations are deterministic and safer under bad inputs.
RotatingMachine confidence now reflects multiple measurement channels.
Output schema expands with power/pressure drift fields.

Rollback Notes

Revert errorMetrics.js and rotatingMachine drift wiring to return to legacy flow-only drift behavior.
