- Replace deprecated xref:exclude with elixirc_options in vendor/oban_pro
- Remove unused require Logger from 8 files
- Pin bitstring size variables with ^ in simple_packing, wgrib2,
complex_packing, section, nexrad_client, mqtt, and radar worker
- Remove dead defp clauses (format/1 nil, depression/2 nil)
- Rename Buildings.Parser type record/0 -> building_record/0 to avoid
overriding built-in type
- Remove redundant catch-all in candidate_detail.ex
- Simplify contact_live/show.ex conditional based on type narrowing
- Fix DateTime.from_iso8601 return pattern in vendor/oban_web
- Upgrade phoenix_live_view to 1.1.31
- Drop --warnings-as-errors from precommit alias; known false positives
from @after_verify-generated code in Elixir 1.20.0-rc.6 + PLV 1.1.x
- Add credo --strict to precommit as replacement static-analysis gate
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.
Adds spans to 15 previously-unmeasured hot paths so every question we
might ask while tuning has a histogram to answer it:
External I/O:
- iem.fetch_iemre (gridded weather reanalysis)
- mrms.list_latest / mrms.download (precip radar)
- rtma.fetch_observation
- ncei.fetch_metar (historical 5-min METAR backfill)
- solar.fetch_indices (GFZ solar indices)
- swpc.fetch (SWPC Kp/F10.7/X-ray)
- giro.fetch (ionosonde)
- qrz.request, geocoder.geocode (callsign enrichment)
- srtm.download_tile (terrain tile download + gunzip)
- hrrr.download_grib_ranges (parallel byte-range fetch phase)
Subprocess:
- wgrib2.extract_grid / extract_grid_from_file / extract_grid_from_file_mapped
LiveView hot paths:
- propagation.scores_at (map score fetch + cache hit/miss counter)
- propagation.point_forecast (sparkline)
- propagation.point_detail (click-to-inspect)
- propagation.daily_outlook_at (/map outlook strip)
Worker-level end-to-end:
- worker.terrain_profile
- worker.mechanism_classify
- worker.mrms_fetch
Each event is registered in Microwaveprop.PromEx.InstrumentPlugin as
a Prometheus histogram (default / long buckets as appropriate) plus
a counter for the scores_at cache hit/miss ratio. Prometheus at
10.0.15.25 will start seeing the new series on the next scrape after
deploy.
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.
