- 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
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.
NCEI ASOS 5-minute data client (Weather.NceiMetarClient):
- fetch/3 pulls per-station monthly .dat files from NCEI C00418
- parse/1 decodes the fixed-width METAR format including precise
T-group temperatures (T02110094 → 21.1/9.4°C)
- metar_5min_observations table: schema-identical to
surface_observations, separate table to avoid mixing cadences
Weather.recent_surface_obs/3 prefers 5-min data when available,
falls back to the hourly surface_observations table.
