fix(dialyzer): clear 125+ warnings under strict flags
Enabled :error_handling, :unknown, :unmatched_returns, :extra_return,
:missing_return in an earlier commit and landed a 129-warning baseline.
Four parallel agents each fixed a directory slice:
- Core contexts (29): Radio, Release, Weather, Beacons, Cache,
Backtest.Features, Terrain.Srtm, Ionosphere.GiroClient,
Propagation.RunTiming, Accounts.Scope, RepoListener. Fixes were
(a) prefix side-effect calls (Task.start, Phoenix.PubSub,
Logger, :ets.new) with _ = ; (b) tighten/widen specs that didn't
match actual returns; (c) add missing @type t declarations;
(d) drop dead parse_int(nil) clause.
- Propagation + weather subdirs (15): FreshnessMonitor, NotifyListener,
ScoreCache, ScoreCacheReconciler, Weather.FrontalAnalysis,
Weather.Grib2.Extractor, Weather.Grib2.Wgrib2, GridCache,
HrrrPointEnqueuer, NexradCache. Same patterns — mostly _ = on
PubSub / :ets / Repo.insert_all; widened two specs (float ->
number) where integer returns were reachable.
- Workers (35): BackfillEnqueue, CanadianSoundingFetch,
ContactImport, ContactWeatherEnqueue, GefsFetch, IemreFetch,
NarrFetch, SolarIndex, TerrainProfile, WeatherFetch. Prefixed
Repo.update_all / Radio.set_enrichment_status! / Weather.upsert_*
side-effect calls. Fixed one :pattern_match in
CanadianSoundingFetch.most_recent_sounding_time/1 where a
tautological cond guard generated unreachable code.
- Web + Mix tasks + lib_ml (46 of 50): controllers, LiveViews,
UserAuth, and 11 mix tasks. Same prefix strategy. 4 remaining
warnings originate in LiveTable.LiveResource dep macro expansion
and can't be fixed without forking the dep — added .dialyzer_ignore.exs
to suppress just those specific file:line pairs.
Also wired ignore_warnings in mix.exs dialyzer config.
mix dialyzer --format short | grep ^lib/ | wc -l -> 0
mix test: 2163 tests, 3 pre-existing flakes, 0 regressions.
