    `EXPLAIN (ANALYZE, BUFFERS)`. Verify partition pruning and the new spatial index.

+   status/operational pages. Prefer bounded batch queries and preloads.~~ **DONE** — audit complete. No high-severity patterns found. Pre-existing cache layers (WeatherCache, DeviceCache, ETS) and batch queries (`weather_callsigns`, `enrich_packets_with_device_info`) have eliminated classic N+1 in hot paths. Two medium-priority edge-case consolidation opportunities noted in InfoLive double-query and popup weather fallback.
 5. Audit mobile and map search for unbounded scans. Add deterministic ordering,
    hard result caps, suitable indexes, and tests that assert the caps.
 6. ~~Review the packet counter migration under concurrent inserts and partition
