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.
Apply mix format to fix formatting issues that were missed before pushing.

When a new deployment occurs in k8s, all connected LiveViews now receive
a notification to update their deployment timestamp display.
Changes:
- Added DeploymentNotifier GenServer that broadcasts deployment events
- LiveViews subscribe to "deployment_events" PubSub topic
- When DEPLOYED_AT env var is set (k8s deployments), a notification is
sent after app startup
- LiveViews handle the deployment event and update their timestamp
This ensures that when a new version is deployed, users see the
deployment timestamp update in real-time without needing to refresh
their browser.
