Convert every context/worker upsert that used the catch-all
`:replace_all_except` form to the explicit `{:replace, [:col1, ...]}`
form. Reviewers can now see exactly which columns an upsert overwrites,
and adding a new column to a schema no longer silently opts it into the
update path.
Behaviour is preserved bit-for-bit: each new explicit list contains
every column the old `:replace_all_except` would have overwritten.
Touched:
- Microwaveprop.SpaceWeather (Kp / F10.7 / X-ray shared helper)
- Microwaveprop.Ionosphere (observation upsert)
- NexradWorker, HrrrNativeGridWorker (insert_all grids)
- CommonVolumeRadarWorker, RadarFrameWorker (per-contact stats)
Also pins the conflict behaviour for the ContactCommonVolumeRadar
upsert path in RadarFrameWorkerTest so a future column addition that
isn't reflected in the explicit list fails loudly.
CommonVolumeRadarWorker and MechanismClassifyWorker were both
returning :ok on upstream failures, so Prometheus job-failure counters
stayed at zero during multi-hour NEXRAD outages and classifier bugs
went unnoticed.
- CommonVolumeRadarWorker: distinguish permanent (4xx) from transient
errors using the same pattern as RadarFrameWorker. Permanent errors
still mark :unavailable + :ok so the backfill stops re-queueing them.
Transient errors return {:error, reason} and leave radar_status alone
so the next retry can succeed.
- MechanismClassifyWorker: keep the row-status :failed update so
operators can see which contacts blew up, but return
{:error, inspect(e)} from the rescue instead of swallowing it as :ok.
Previously the CommonVolumeRadarWorker ran silently — no URL logged,
no sign in the logs that it was doing any work. Added info-level
fetch/ok/error logs in NexradClient (same shape as WeatherFetchWorker
RAOB logs) plus start-of-work + ingestion lines in the worker itself.
Unchanged: the existing "no frame" warning and all control flow.
