Both RTMA and METAR5 schemas + clients + workers were defined but
never had a consumer. `find_nearest_rtma/3` and `recent_surface_obs/3`
existed in `Microwaveprop.Weather` with zero callers cluster-wide;
RtmaFetchWorker had test coverage but was never enqueued anywhere;
no IEM 5-min ASOS fetcher was ever written. The tables sat empty in
prod and the recalibrate audit was permanently flagging them BROKEN
even though the empty state was the steady state.
Drop the lot — schemas, clients, workers, queue config, Req.Test
stubs, audit checks, and the per-table unique tests in the
observation-changesets suite. New migration drops the now-unreferenced
`rtma_observations` and `metar_5min_observations` tables (both 0
rows in prod). Trim the `:rtma` slot out of `backfill_only_queues`
in runtime.exs so Oban Pro's Smart engine stops trying to manage a
queue with no producer.
Audit thresholds reset on the surviving NARR check: drop the
"WARN < 5000 absolute rows" rule that didn't account for
NarrFetchWorker's 0.13° spatial dedup, and point remediation at
the existing BackfillEnqueueWorker cron instead of the dev-only
`mix narr.backfill` task.
scripts/recalibrate_algo.py: ROW_COUNT_SOURCES + DATA_GAP_SQL +
DATA_GAP_RULES all stop referencing the dropped tables.
- SwpcClient: unparseable time_tag rows drop silently, integer / string
numerics both cast, already-decoded list bodies (Req auto-decode) are
accepted, non-JSON-array bodies return {:error, :not_a_list}, X-ray
rows whose energy isn't the long wavelength are filtered, and the
misspelled-upstream electron_contaminaton key flags
electron_contaminated.
- UwyoSoundingClient: every month abbreviation routes to its correct
number, bogus month tokens fall through to an empty result, and
short-of-fixed-width lines are skipped without raising.
- Grid.wgrib2_grid_spec/0: lon/lat_start anchor to the SW corner,
steps match Grid.step/0, cell counts span CONUS inclusive, and the
spec's cell product equals length(Grid.conus_points/0).
- PollWorker: empty-link list is a no-op, and poll_fn receives host /
community / radio_type straight from the link row.
- Contact submission_changeset: antenna heights are bounded to
[0, 1000] ft, whitespace-only mode normalises without firing an
invalid-mode error, plus a pair of StreamData properties — every
sanctioned band validates and every out-of-list band string is
rejected.
Suite: 2,380 tests + 148 properties (was 2,370 + 146); coverage
70.38% → 71.08% total; credo strict clean.
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.
Two unrelated production warnings from the same log window:
WeatherFetchWorker raised Postgrex 21000 cardinality_violation on
ASOS upserts when IEM returned two METAR records for the same
timestamp (routine + special at the same minute). Dedupe by
(station_id, observed_at) in upsert_surface_observations, keeping
the last occurrence since IEM's ordering is chronological.
SwpcClient.fetch_xrays warned with the full truncated response
body (~650 KB of GOES X-ray JSON) dumped into the log aggregator
whenever SWPC's CDN cut the response mid-stream. Intercept
Jason.DecodeError in fetch_and_parse and format it short: keep
the byte position and an 80-char preview, drop the rest.
6 additional characterization tests for empty-list upsert paths, station
filter isolation on latest_observation/1, multi-band xray coexistence,
and newest-across-time/bands latest_* helpers.
Adds the second ionospheric data source layer. Polls NOAA SWPC's free
public JSON services every 5 minutes for three products:
* Planetary K-index (1-min cadence) → geomagnetic_observations
* 10.7 cm solar flux (hourly) → solar_flux_observations
* GOES X-ray flux (1-min, 0.1-0.8nm long-wave band only) →
solar_xray_observations
All three products feed HF / Es scoring inputs that the propagation
engine will start using in a follow-up commit:
* Kp drives HF absorption and Es damping (memory notes Kp is inversely
correlated with tropo/Es stability).
* F10.7 is the SSN proxy for ITU-R P.533 HF MUF prediction.
* GOES X-ray long-wave flux is the short-wave fade (SWF) / D-layer
absorption proxy — a C-class flare starts attenuating HF within
seconds of the X-ray peak.
New context `Microwaveprop.SpaceWeather` exposes `upsert_*/1` and
`latest_*/0` per product; `SpaceWeatherFetchWorker` pulls all three
independently so one endpoint's outage doesn't block the others.
Fixtures captured from live SWPC endpoints on 2026-04-15 for the
parser tests.
Not yet wired into scoring — that's a separate commit.
