- Beacon detail endpoints (LiveView + REST API) now hide unapproved beacons from anonymous and unauthorized viewers; only the submitter and admins can see pending records before approval. Adds Beacons.get_visible_beacon/2 with scope-aware checks. - API contact pagination now honors per_page end-to-end. Radio.list_contacts/1 accepts :per_page and clamps to 200. - API rate limiter: ETS table is now owned by a long-lived Sweeper GenServer (won't die with a request task); Sweeper periodically prunes expired-window rows to bound memory; init_table/0 race is rescued. - /scores/cells and /weather/cells: add per-IP rate limiting and a shared GridBounds clamp/413 guard so global / oversized viewports no longer drive unbounded binary responses. - NEXRAD PNG unfilter (sub/up/average/paeth): replace acc++[byte] + Enum.at(acc, idx-bpp) with O(n) binary recursion. Decode time for the 12200x5400 n0q frame goes from quadratic to linear. - LiveTableFooter.parse_page and ScoresFile.fetch_bound: switch String.to_integer/String.to_float to Integer.parse/Float.parse, fall back to defaults instead of raising. - PathLive and MapLive band-event handlers: replace String.to_integer(params["band"]) with parse_int / parse_band_param so a non-numeric band parameter no longer crashes the LiveView.
