Helpers class

Miscellaneous helpers shared across layers: payload sanitization and small math utilities for the risk engine.

Signing/verification lives in CryptoUtils (real HMAC-SHA256, via package:crypto) rather than here.

Properties

Static Methods

clampRisk(double value) double
Clamps value into the inclusive [0.0, 1.0] risk-score range.
sanitize(dynamic value) → dynamic
Recursively strips control characters and trims strings within a payload (map, list, or scalar), returning a sanitized deep copy. This is a lightweight defense against injection-style payloads — it does not replace proper output encoding at the data-sink layer.
