Phase 3 Stream C Elixir-side: HrrrFetchWorker is deleted; per-QSO HRRR
enrichment now writes to the new hrrr_fetch_tasks table for the Rust
hrrr-point-worker to drain.
Table shape:
- one row per valid_time (primary key) with a JSONB array of
{lat, lon} points
- UPSERT on conflict: array-union of points, status flips back to
queued if previously done/failed so a backfill re-scan naturally
refills the queue for Rust
Elixir changes:
- new migration 20260419231502_create_hrrr_fetch_tasks
- new Microwaveprop.Weather.HrrrPointEnqueuer with enqueue/1 and
enqueue_for_contacts/1. Pre-2014 contacts (NARR's territory)
are skipped here so hrrr_status can pin them to :unavailable.
- ContactWeatherEnqueueWorker: build_hrrr_jobs/1 removed; single-
contact path and batch perform/1 both route through
HrrrPointEnqueuer.enqueue_for_contacts/1. A placeholder jobs-list
is kept just to feed mark_hrrr_status!.
- contact_live/show.ex retry button enqueues via the same path.
- :hrrr queue removed from dev/config/runtime.exs
- HrrrFetchWorker module + test deleted
BackfillEnqueueWorker scans continue to flow through
ContactWeatherEnqueueWorker.enqueue_for_contact (unchanged), so the
30-min reconcile refills hrrr_fetch_tasks automatically.
4 new tests cover the routing, pre-2014 skip, UPSERT-union, and
status-reset-on-reschedule behaviour. Rust-side hrrr-point-worker
binary + k8s deployment land in the next commits.
