Adds ~600 new test cases (2013 → 2613 tests; 170 properties; 0
failures) across 12 new test files plus expansions of eight existing
files. Big lifts per module:
ContactLive.Mechanism 33 → 100%
MetricsPlug 54 → ~100%
Microwaveprop.Release 15.8 → 70%+
Telemetry 38 → 76%
HrrrNativeGridWorker 27.7 → 76%
ContactLive.Show 34 → 48% (handler + render branches)
Admin.ContactEditLive 49.7 → 70%+
GefsFetchWorker 35.8 → ~55%
IonosphereFetchWorker 56.3 → 75%
PathLive 58.9 → 67%
WeatherMapLive 66.9 → 80.2%
RoverLive 0 → 70.3%
ContactMapLive 59.2 → 89.8%
ContactMapController 0 → 100%
Mix tasks (Rust.Golden, Notebook, Backtest, HrrrBackfill,
HrrrClimatology, HrrrNativeBackfill, NexradBackfill,
RadarBackfill, ImportContestLogs, PropagationGrid,
ResetEnrichment, Hrrr.PurgeGridPoints) 0 → ~60-100%
Two incidental fixes made while adding tests:
- ContactLive.Show.handle_event("toggle_flag", ...) was passing
socket.assigns.current_scope to admin?/1 instead of socket.assigns,
so admins never matched the pattern and every toggle ran the
"Admins only." flash branch. Flag now toggles for admins again.
- Commercial.PollWorker.fetch_weather/1 promoted from private to
@doc'd public so the IEM-fetch + ASOS-upsert path can be tested
directly without driving perform/1 through live SNMP (which was
timing out for ~50 s per test in the earlier attempt).
Stable property-test additions cover the dewpoint-from-RH monotonicity,
nearest_run/1 idempotence, and the ionosphere station envelope.
