Sweep of remaining swallowed-error sites flagged by an audit pass:
- weather/gefs_client.ex: byte-range download task exits log url + reason
before being surfaced as {:error, _} (matches the HRRR fix).
- live/path_live.ex: terrain-profile load failure, native-duct lookup
failure, and ProfilesFile.read failure now log warnings with path
endpoints / midpoint / valid_time. Previously rendered a degraded
result silently.
- live/rover_live.ex: station-mutation {:error, _} now logs id + reason
instead of dropping into {:noreply, socket}.
- application.ex: the boot-time backfill_missing_home_qth Task.start is
now wrapped in try/rescue. A DB issue at boot would have crashed the
task silently (no Logger handler attached pre-Logger crash format).
Wrap a Task.Supervisor in a PartitionSupervisor (one partition per
scheduler) and route the four sustained async_stream callers through
`{:via, PartitionSupervisor, {Microwaveprop.TaskSupervisor, self()}}`.
Concurrent work — the hourly PropagationGridWorker pulling f00-f18
HRRR range downloads, the GEFS worker scoring its grid, and the
Recalibrator's 20-way positive/negative fan-out — no longer funnels
through a single supervisor PID.
Light/one-shot Task.async + Task.start sites (hrrr_client surface/
pressure fan-out, application boot warmup, weather fire-and-forget)
are left alone; partitioning only helps under sustained concurrency.
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.
