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.
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.
