Each fix is covered by a regression test that fails on `main` and
passes on this commit.
Round 1 (initial review):
* propagation: thread `latitude` into the conditions map so
`score_season/4` actually picks up regional multipliers
* hrrr_client / fetcher.rs: `nearest_hrrr_hour` rounds DOWN, never at
a future cycle that NOAA hasn't published yet
* radio: spherical-vector great-circle midpoint replaces the
arithmetic mean — anti-meridian paths no longer fold to Greenwich
* weather: `reconcile_weather_statuses` scales the longitude band by
`1 / cos(lat)` so the bbox stays ~150 km wide at every latitude
* radio/maidenhead: clamp 90°/180° below the field-bucket overflow so
`from_latlon` never emits invalid characters like 'S'
* prop_grid_rs/pipeline: merge HRRR + NEXRAD-derived rain rates and
read `best_duct_freq_ghz` into `best_duct_band_ghz` so the Native
Duct Boost actually fires
* propagation/region (Elixir + Rust): inclusive upper bounds so points
exactly at lat_max get the regional multiplier
* weather/sounding_params (Elixir + Rust): drop the 10 m gradient
floor so HRRR's thin near-surface layers stop hiding sharp ducts
* weather/sounding_params: when the profile ends inside a duct,
finalize it with the highest sample as the top instead of throwing
it away (Rust port already correct)
Round 2 (post-fix sweep):
* radio + commercial: single canonical haversine in Radio (atan2
form); Commercial delegates instead of carrying a second copy that
could disagree at threshold distances
* prop_grid_rs/profiles_file: `snap_coords` matches Elixir's
step-aware snap (`round(coord/0.125) * 0.125`, then 3-dp round) so
Rust-keyed and Elixir-keyed profile maps land on the same cell
* weather/grib2/wgrib2: `parse_lon_val_segment` uses `Float.parse`
uniformly — wgrib2 dropping the trailing `.0` from a longitude no
longer crashes the whole chain step
Rework of d61fbd3's dialyzer suppression: the 4 warnings from
LiveTable.LiveResource's macro expansion are now fixed at the
root rather than hidden via .dialyzer_ignore.exs.
Changes:
- Delete .dialyzer_ignore.exs and remove ignore_warnings from
mix.exs. No more hidden suppressions.
- New MicrowavepropWeb.LiveTableResource shim that wraps
use LiveTable.LiveResource and overrides:
* maybe_subscribe/1 — explicit :ok = on Phoenix.PubSub.subscribe/2
(previously discarded, tripping :unmatched_return).
* handle_info/2 — explicit _ = on File.rm, Process.send_after.
Switch all 4 LiveTable-using LiveViews (contact_live/index,
beacon_live/index, admin/contact_edit_live, user_management_live/index)
to use MicrowavepropWeb.LiveTableResource instead.
- New priv/dep_patches/live_table-0.4.1.patch adds _ = in front of
LiveTable.LiveSelectHelpers.restore_live_select_from_params/2 in
the dep's macro-expanded handle_params/3. The call's return was
silently discarded, tripping the fourth warning per LiveView.
- New lib/mix/tasks/deps.patch.ex applies every
priv/dep_patches/*.patch to its target dep idempotently after
mix deps.get. Wired into the :setup alias + overridden
mix deps.get so the patch survives cache regeneration in CI.
- Other modified files in this commit are the spec-coverage
additions from the parallel agent pass (beacons.ex,
commercial.ex, propagation.ex, weather.ex, narr_client.ex,
run_timing.ex, 3 workers) — tighter specs for bounds, tuple
shapes, schema-typed params. Dialyzer remains at 0 after
the changes.
Upstream TODO: send a PR for the live_table `_ =` fix. Once
merged and released, drop the patch + mix task + bump the dep.

PropagationPrune ScoresFile), 0 regressions.
PropagationGridWorker.merge_commercial_link_data/2 called
Commercial.link_degradation_at twice per grid cell (once to count,
once to merge), and each call re-ran enabled_links plus two sample
queries per in-range link. That was ~500k SQL queries per forecast
hour — fine for the DB but catastrophic for log volume in dev
iex sessions trying to watch a chain step run.
Split into two new functions:
* build_link_lookup/2 does all the DB work up front — one
enabled_links query + one link_degradation per enabled link
(~10 queries total).
* link_degradation_from_lookup/3 is pure: takes a (lat, lon)
and the precomputed lookup, returns the aggregate or nil.
The worker now calls build_link_lookup once per forecast hour and
the per-cell path is haversine-only. Net: 500k queries → ~10.
PipelineStatus freshness detection moves off oban_jobs.completed_at
onto ScoresFile.latest_valid_time(). The on-disk files ARE the data
the map renders from, so the chip's "Up to date · Nm ago" and the
2h stale threshold now track actual data presence. Running-state
detection still comes from oban_jobs since the chain step is still
an Oban row. Tests updated to seed a ScoresFile instead of a
completed Oban row for the idle/stale cases.
Three signal sources we already collect but weren't using:
* NEXRAD composite reflectivity → rain rate via Marshall-Palmer, taken
as max of HRRR-derived and NEXRAD-derived rate so fast convective
cells between HRRR hourly analyses can still trigger the rain penalty.
Only active on f00 — forecast hours can't see future radar. New
Scorer.dbz_to_rain_rate_mmhr/1 with 5 dBZ noise floor and 150 mm/hr
hail-safe ceiling.
* hrrr_native_profiles.best_duct_band_ghz → Scorer.score_refractivity/4
applies a 1.15× boost when the cell's native-resolution duct supports
the target band's frequency. HRRR pressure-level gradients
systematically under-read thin trapping layers the native profile can
resolve. Sub-band ducts do NOT boost — they're evidence that the
gradient we have is all there is at the target frequency.
* Commercial LOS link rx_power fading → inverse tropo sensor.
Commercial.link_degradation_at/3 computes the average 7-day-baseline
vs current delta across enabled links within 75 km, ignoring links
where link_state != 1. Scorer.commercial_link_boost/2 adds +2 to +25
to the composite score for 3+ dB of fading. ~150 km radius around
DFW is the only zone this helps today, but it's the first *measured*
signal in the algorithm vs the model-derived proxies.
Also fix a latent test bug exposed by the earlier ERA5 poll-timeout
bump: era5_batch_client_test's "uncached path returns error" tests
hung for up to an hour when run with direnv's real CDS key. New
describe-level setup explicitly unsets the env var so the tests stay
hermetic.
