+"""Fanout module for uploading heard advert packets to map.meshcore.dev.
+
+Mirrors the logic of the standalone map.meshcore.dev-uploader project:
+- Listens on raw RF packets via on_raw
+- Filters for ADVERT packets, skips CHAT nodes (device_role == 1)
+- Applies per-pubkey rate-limiting (1-hour window, matching the uploader)
+- Signs the upload request with the radio's own Ed25519 private key
+- POSTs to the map API (or logs in dry-run mode)
+
+Dry-run mode (default: True) logs the full would-be payload at INFO level
+without making any HTTP requests. Disable it only after verifying the log
+output looks correct — in particular the radio params (freq/bw/sf/cr) and
+the raw hex link.
