Turned on :error_handling, :underspecs, and :unmatched_returns in
mix.exs dialyzer config. The 97 warnings this surfaced were fixed in
place rather than suppressed:
- unmatched_return (79): explicit discard with `_ = ...` for
fire-and-forget side effects (Process.cancel_timer, :ets.new,
send/2), and pattern-matched `:ok = ...` for control-plane
Phoenix.PubSub subscribe/unsubscribe/broadcast calls so a future
return-shape change fails loud.
- contract_supertype (18): tightened @spec arg and return types on
data_builder, historical_loader, url_params, packet_utils,
encoding_utils, aprs_symbol, weather_controller, packet_replay to
match each function's actual success typing.
No behavioural change. mix compile clean, 1008 tests pass, dialyzer
count is now 0.
- Fixed info page not receiving live updates by implementing callsign-specific PubSub topics
- Added automatic time counter for "Last Position" and other timestamps using JavaScript hook
- Optimized map updates to only move marker instead of reloading entire map
- Fixed APRS parser to properly handle [000/000/A=altitude format in comments
- Removed packet caching on info page for real-time updates
The info page now properly subscribes to updates for the specific callsign being viewed,
timestamps automatically count up without page refresh, and the map smoothly animates
marker position changes instead of flickering with full reloads.
