Changes under lib/ (source):
- iemre_fetch_worker: replace `if transient_failure?/1` boolean predicate
+ `if/else` with a classifier that pattern-matches the error reason
directly, returning `:transient | :permanent`, and dispatch via
`case`. Three-clause head is clearer than the boolean predicate.
- scores_file.extract_points and nexrad_client.extract_box: force `//1`
step on the row/col comprehensions so an image box whose centre
lands outside the raster collapses to an empty iteration instead
of firing Elixir 1.19's ambiguous-range warning. Adds a regression
test for the right-edge box.
Test coverage added:
- Feature wrappers in Backtest.Features (theta_e_jump, shear_at_top,
duct_thickness, best_duct_freq, duct_usable_for_band,
distance_to_front / parallel_to_front stubs, all_features/0).
- NotifyListener handle_info tolerance for malformed payloads +
unknown messages, plus the PubSub broadcast side effect.
- Viewshed.effective_reach_km across every verdict / diffraction
tier / ducting-score tier combination.
- SnmpClient parse_af60_output unit conversions + unknown-column
handling; parse_snmpget_output OID normalisation and junk-line
tolerance.
- HrrrNativeClient native_level_count, native_variables,
native_messages shape, duct_messages / duct_byte_ranges.
- Changeset coverage for GeomagneticObservation, SolarFluxObservation,
SolarXrayObservation, Ionosphere.Observation, HrrrClimatology, and
Metar5minObservation — lifted each from ~50% / 0% to 100%.
- Property tests: GefsClient.dewpoint_from_rh invariants (Td ≤ T,
monotonic in RH, finite across the operating envelope) + idempotent
nearest_run. NexradClient.pixel_to_dbz monotonicity + bounded
output; latlon_to_pixel round-trip for every grid cell.
Also cleared several unrelated compiler/linter warnings:
- Three private test helpers (create_contact, insert_contact,
current_hour) had `\\ %{}` / `\\ 0` defaults that no caller used.
- profiles_file_test bound `dir` in a pattern match without using it.
Suite: 2,359 tests + 146 properties pass (was 2,300 / 139); coverage
70.38% → 70.89%; credo strict clean.
Wires the GEFS fetch pipeline into the existing scoring machinery:
- GefsFetchWorker runs Propagation.score_grid_point over every
fetched grid cell and persists the result via replace_scores/2, so
Day 2-7 valid_times show up on the map through the same
Propagation.scores_at/3 path HRRR uses
- Empty-args perform/1 seeds the chain by enqueueing f024-f168 (25
jobs at 6-hour cadence) for the most recent GEFS run that should
be published given NOMADS' ~3-4h publication lag
- Cron: seeds at 05:30, 11:30, 17:30, 23:30 UTC — 5 hours after each
00/06/12/18Z run
- GefsClient.build_profile now emits :wind_u / :wind_v atom keys to
match the scorer's input shape; DB columns keep the *_mps suffix
for unit clarity, remapped at write time
GEFS pgrb2a lacks HPBL, native-level duct data, NEXRAD, and
commercial-link degradation — the extended-horizon score is a
rougher signal than the HRRR-driven one but covers the window HRRR
can't reach.
- GefsClient.build_profile/1: converts raw wgrib2 output into the
scorer-shaped profile, deriving Td from RH via Magnus at both the
surface and each pressure level
- GefsClient.fetch_grid_profiles/3: downloads the idx sidecar from
NOMADS, byte-ranges only the surface messages, hands the slim
GRIB2 binary to wgrib2 -lola for bilinear regridding from 0.5°
onto the CONUS 0.125° grid
- GefsFetchWorker: one Oban job per (run_time, forecast_hour),
upserts into gefs_profiles and runs SoundingParams.derive so the
same refractivity/ducting metrics flow through
Oban gets a new :gefs queue (2 slots dev/config, 1 slot per prod
pod). Test env gets a gefs_req_options Req.Test stub slot so future
integration tests can drive the full fetch path. No cron wiring or
scorer integration yet — that's Step 3.
Lays the groundwork for a Day 2-7 propagation outlook driven by NCEP
GEFS ensemble-mean output, picking up where HRRR's 18-hour horizon
leaves off.
- GefsClient: NOMADS URL builder, forecast-hour list (3h to +240,
6h to +384), ensemble-mean message inventory, and a Magnus
dewpoint derivation (pgrb2a publishes RH rather than Td)
- gefs_profiles table + GefsProfile schema mirroring hrrr_profiles
so the scorer can run over rows from either source
- Weather.upsert_gefs_profile/1 and upsert_gefs_profiles_batch/1
No worker or UI yet — those land in follow-up commits.
