Builds ship in three channels — dev (CI artifacts), -rc (community testing), and stable (the “Latest” release). The gate is real-hardware validation, not just a green build.
Deep technical docs (observer CLI, SafeBoot, packet format) are in the firmware docs — also reachable from the docs hub. Source: meshcore-firmware.
