- Database triggers on contacts and oban_jobs fire pg_notify on
status/state changes
- RepoListener GenServer subscribes via Postgrex.Notifications and
broadcasts to PubSub
- Backfill dashboard subscribes to PubSub instead of 2-second polling
- Eliminates periodic SELECT queries, updates arrive instantly
- Migration renames table, column, all indexes, and FK constraints
- Contact schema now references "contacts" table
- TerrainProfile foreign key renamed from qso_id to contact_id
- All code and tests updated to use contact_id
The 6 sequential count(*) queries on large tables were timing out
at 15s when concurrent HRRR batch inserts held locks. Reuse the
n_live_tup estimates already fetched from pg_stat_user_tables.
- Enrichment status breakdown per type (HRRR/Weather/Terrain/IEMRE)
with color-coded status counts (complete/pending/queued/failed)
- Database overview: total DB size, HRRR profiles, observations,
soundings with per-contact averages
- Table sizes: rows and disk size per table, sorted by size
- All stats auto-refresh every 2 seconds
- Radio.ensure_positions!/1 computes pos1/pos2/distance from grids
- Called in contact show page mount and enqueue_for_contact
- Migration backfills positions for existing contacts missing them
- Migration corrects enrichment statuses based on actual data presence
- Backfill dashboard includes contacts with grids but no positions
- New fields: hrrr_status, weather_status, terrain_status, iemre_status
with values: pending, queued, processing, complete, failed, unavailable
- EnrichmentStatus module defines valid state transitions
- Migration backfills: queued=true → complete, false → pending
- Workers set status on transitions (queued on enqueue, complete on finish)
- Show page reads status from contact struct, not computed dynamically
- Backfill dashboard queries status fields for accurate progress counts
- Remove cron-scheduled ContactWeatherEnqueueWorker (enrichment only on
submission, page view, or manual backfill)
- Partial indexes on status != 'complete' for fast unprocessed lookups
- Input field to enqueue N contacts for backfill
- Live stats: unprocessed contacts, active/queued jobs, completed/hour
- Per-worker breakdown: executing (with spinner), available, retryable
- Auto-refreshes every 2 seconds
