Pull Request Overview
This PR adds a validation step to drop incoming NodeInfo packets when the is_licensed flag doesn’t match the local owner’s flag, preventing acceptance of invalid packets.
- Introduce a guard in
handleReceivedProtobufto comparep.is_licensedwithowner.is_licensed - Log a warning and return early to drop mismatched packets
Comments suppressed due to low confidence (1)

is_licensedscenarios to verify that packets are correctly accepted or dropped.
if (p.is_licensed != owner.is_licensed) {

While triaging other issues, it became apparent that we accept invalid NodeInfo packets, regarding is_licensed. Closing that loophole
