- Add Weather.GridCache: ETS cache of derived HRRR grid rows keyed by valid_time, cluster-synced via PubSub. Eagerly warmed from PropagationGridWorker after each upsert so /weather map pan/zoom and weather_point_detail hit zero DB on warm cache. - Replace latest_weather_grid DB query path with cache-first lookup + DB fallback. hrrr_profiles is 42M rows partitioned; pulling 3-10k rows per viewport on every pan was the main cost. - ContactLive.Show: defer the heavy enrichment loads (weather, solar, HRRR, terrain, IEMRE, elevation profile, ITU-R propagation analysis, data_sources) into a handle_info(:hydrate) that runs after the shell renders. Initial mount now returns nil placeholders; template already had :if guards for all of them. Shell-to-first-paint goes from ~500ms-2s down to ~20ms. - Cache fetch_queue_counts for 5s in ContactLive.Show — oban_jobs group by query was running on every contact page view. - Backfill stats: wrap count_unprocessed, fetch_stats, fetch_db_stats in Microwaveprop.Cache with 2-5s TTLs; bump refresh debounce from 1s to 2s so bulk enrichment events don't thrash the DB.
