Normalize Hex Strings for Device APIs

🧩 Problem

Hex strings arrive with prefixes, spaces, or inconsistent casing. When malformed or unstructured data hits routers, filters, or API connectors, entire automations halt or silently drop records. Teams end up retrying runs, hand-editing payloads, and explaining delays to customers.

💡 Why This Happens

Humans and tools format hex differently; devices expect strict format. Most automation platforms assume well-formed payloads and do minimal validation. AI models, third-party APIs, and changing vendor schemas drift over time, mixing encodings, formats, and unexpected fields that downstream steps cannot tolerate.
