Guides

These guides are written to help you interpret real-world error code families and choose safe, high-signal next steps. Each guide stands on its own, and also links into the relevant hubs and code pages for deeper diagnosis.

Every guide follows the same structure: symptoms, root causes, prioritized fixes, what to avoid, escalation checklists, and a curated code directory.
