# Payload Notes

Use this folder for protocol-level findings.

Examples:

- packet captures
- field maps
- command and response notes
- unknown byte ranges
- per-model payload differences

For each note, prefer recording:

- model
- firmware or hardware revision if known
- sample payload
- decoded meaning
- confidence level
