- CacheTest: fix sweep timing race by using negative TTL (-1)
instead of positive TTL (1) for already-expired entries
- ScoreCache: replace ETS match-spec DateTime comparisons with
:ets.foldl + DateTime.compare — DateTime structs are maps in
Elixir >= 1.15 and ETS can't compare maps with :< / :> guards
- Accounts: drop unsupported returning: true on delete_all,
return [] for expired tokens list
- Backtest: catch ArgumentError from String.to_existing_atom
for unknown feature names, preserving the helpful Mix.Error
- ContactLive IndexTest: invalidate monthly_bars cache before
assertion so test data is visible
- RoverLocationsLive MapTest: invalidate cached points before
assertion
- StatusLiveTest: add DB cleanup in setup to reduce test
interference; parameterize NARR candidate coordinates
