Engineering notes, not press releases. Everything here is drawn from the project’s normative docs and real bench sessions — where a post describes something that isn’t shipped, it says so in the text.

All posts are currently launch drafts, pending a final human editorial pass before the site goes public.

The return path is not the forward pathLoRa links are asymmetric and every mesh stack pretends otherwise. How LoRa Relay Chat picks a return lane by delivery-probability-per-airtime — and why 'fastest' and 'best' are different questions.
