Submit and contact-detail forms now use a plain text input for the QSO
timestamp with a "YYYY-MM-DD HH:MM" placeholder and regex pattern. The
native datetime-local input ignores lang="en-GB" on macOS/iOS when the
system clock is 12-hour, so it was rendering AM/PM against the user's
wishes. Ecto's :utc_datetime cast already accepts this format (verified
space+seconds, T+seconds, and both with and without seconds/Z).
Contact edit workflow grows a third branch: admins still apply directly,
non-owners still go through the admin review queue, and now logged-in
owners of a contact (user_id == current_user.id) can apply edits
directly too. New helpers Radio.owner?/2 and Radio.apply_owner_edit/3
reuse the existing normalize + diff + apply_edit_to_contact path so the
grid-change → enrichment re-enqueue pipeline kicks in automatically.
Anonymous contacts (user_id nil) and other users' contacts both return
{:error, :not_owner}.
Nine new tests cover owner?/2 and apply_owner_edit/3 including the
no-changes, wrong-user, and anonymous-contact paths.
- Add ContactMapController serving /api/contacts/map with pre-gzipped
JSON from Microwaveprop.Cache. Browsers handle Content-Encoding: gzip
natively; payload drops from 5.7 MB raw to 1.5 MB on the wire (73%).
Cache TTL 10 min, invalidated on contact insert alongside the other
contact-map cache keys.
- Move contact map payload out of the LiveView's initial HTML entirely.
Shell renders with the filter chrome (count + band list); the hook
fetches contacts from the HTTP endpoint in parallel with map init.
This also avoids Phoenix.Socket's 64 KB frame limit (push_event would
have required chunked transfer or a global frame size bump).
- Parallelize ContactLive.Show hydrate: five independent DB loads
(weather, solar, hrrr_path, terrain, iemre) now run concurrently via
Task.async + Task.await_many. Total latency drops from sum(each) to
max(each), cutting contact show hydrate time roughly 5x.
- Add contacts_inserted_at_desc_id_desc_idx so /contacts list runs as an
Index Scan (~0.4ms) instead of a Seq Scan + top-N heapsort (~77ms on
58k rows)
- Add Microwaveprop.Cache: tiny ETS-backed TTL cache for memoizing
expensive-but-stale-tolerant values
- Cache total_entries for unsearched /contacts page loads (30s TTL,
invalidated on insert)
- Cache the entire /contacts/map payload (pre-encoded JSON + band list),
moving load_contacts into Radio.contact_map_payload; invalidated on
new contact insert. Mount goes from ~150-300ms to ~5ms.
- Fix /map overlay blinking on load: reuse the Leaflet GridLayer across
renderScores calls and just redraw() against the updated ScoreGrid,
instead of removeLayer + new layer which flashed between tile regens
- Make mode optional on submission: schema change (null: true),
submission_changeset no longer requires it, blank strings normalise to
nil, CSV import accepts 6-column (no mode) or 7-column layouts
- core_components .input adds a red asterisk to labels when required,
giving users a visual cue for which fields must be filled on /submit
1. Prevent user_id impersonation in contact submissions
- Remove user_id from submission_changeset cast fields
- Pass user_id as a separate server-side argument to create_contact/2
- Client form params can no longer forge account-linked contacts
2. Restrict flag toggle to admins only
- Add admin? guard to toggle_flag event handler
- Hide flag button from non-admin users in template
3. Reset enrichment on timestamp edits
- Add qso_timestamp to the fields that trigger enrichment reset
- Prevents stale weather/HRRR/IEMRE data after time changes
Aliases: add module aliases for 9 nested module references
Apply: replace apply/3 with direct module attribute calls
Line length: break 1 long spec line
Refactoring: extract helpers to reduce complexity and nesting
in show.ex, radio.ex, weather workers, terrain, duct detection,
backfill dashboard, contact map, and mix tasks
- Replace %Struct{} with Struct.t() in all @spec annotations
- Replace length(x) > 0 with x != [] in test assertions
- Fix multi-line spec struct references in weather.ex
- Add belongs_to :user on Beacon schema, preload in get_beacon!/1
- Show "Submitted by {callsign}" on beacon detail page
- Add NTMS donation link on the about page
- Change grid preference text to 8 characters (e.g. EM12kp37)
Registered users can suggest edits to any contact's core fields
(callsigns, grids, band, mode, timestamp). Edits enter an admin
approval queue with field-by-field diff view. On approve, changes
are applied and enrichment re-enqueued if grids/band changed.
Users receive email notification on approve or reject.
Also updates dependabot.yml for mix ecosystem.
When a contact is linked to a logged-in user account, display that
user's callsign in the Submitted column instead of a generic "Yes".
Anonymous submissions still show "Yes"; scraped contacts show an em
dash.
- Fix score_pressure crash on nil pressure_mb (coastal HRRR points)
- Set 10-min timeout on grid score upsert transaction (was :infinity)
- Single DELETE for prune_old_scores instead of N queries in a loop
- Remove dead load_hrrr_refractivity that loaded 95k rows into nil map
- Pass selected_time to point_detail to skip latest_valid_time sub-query
- Batch station existence checks (1 query per path point, not per station)
- Batch solar index upserts via insert_all in chunks of 500
- Batch backfill_distances via single UPDATE FROM VALUES statement
- Add is_grid_point boolean + partial index to hrrr_profiles (replaces
non-sargable modular arithmetic filter on every weather map query)
- Add partial index on contacts(qso_timestamp) WHERE pos1 IS NOT NULL
- Move backfill enqueue to Oban worker so UI returns immediately
- 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
- Overlay HRRR duct layers on elevation profile chart (green bands)
- Add flagged_invalid field to contacts with toggle button on detail page
- Fix prune_old_grid_profiles to only delete 0.125° grid profiles,
preserving QSO-linked HRRR data at arbitrary positions
- Auto-enqueue HRRR fetch when viewing contact without HRRR data (<48h)
- Compact solar conditions and contact details layout
- Add band/mode/distance info line to elevation profile section
Rename all modules, functions, variables, routes, and UI text from
qso/qsos to contact/contacts. Database table stays as "qsos" to avoid
migration. Add /qsos -> /contacts redirects for old URLs.
ML Integration:
- Load trained model at app startup, cache compiled predict fn in persistent_term
- Grid worker uses batched ML prediction (10K chunks) when model loaded,
falls back to algorithm scorer when not
- ML score replaces composite, algorithm factor scores preserved for detail view
- Fix process explosion: single EXLA call per chunk instead of per-grid-point
QSO Features:
- Callsign search (ILIKE on station1/station2) with trigram indexes
- Reciprocal QSO grouping (same pair, same band, same hour)
- Wider layout (max-w-7xl) for data table pages
- QSO Training Data link on map page
Infrastructure:
- Re-enable hourly propagation grid worker in dev
- Track ML model weights in git for Docker builds
- Add btree indexes on qsos (timestamp, band, distance_km)
- Remove nav icons from layout header
Enqueue worker now gathers atmospheric data at pos1, midpoint, and pos2
along each QSO path instead of only pos1. Existing has_* guards prevent
duplicate fetches at each grid point.
- Add Radio.qso_path_points/1 for path point extraction
- Update hrrr_job_for_qso, iemre_job_for_qso, jobs_for_qso to iterate path points
- Refactor Weather into find_nearest_hrrr/3 and find_nearest_iemre/3
- Add hrrr_profiles_for_path/1 and iemre_for_path/1 query functions
- Add mix reset_enrichment task to trigger re-processing
- Add precip_1h_in and wx_codes fields to ASOS surface observations
- Add IEMRE reanalysis schema for radar-derived hourly precipitation
- Add IemreFetchWorker with exponential backoff and idempotency
- Integrate IEMRE enqueue into cron weather backfill pipeline
- All existing QSOs marked iemre_queued=false for automatic backfill
- Defensive grid-to-coordinate resolution in create_qso (case instead of crash on match failure)
- Log warning when Oban weather enqueue fails instead of silently dropping
- Add 30s per-session submission cooldown to prevent rapid-fire submissions
Maidenhead grid module converts grid squares to lat/lon coordinates.
Submission form validates grids, bands, modes, and email, computes
positions and distance, then triggers the weather/HRRR/terrain
processing pipeline via Oban.
Fetch elevation data along the path between two stations via the
Open-Meteo Elevation API (with Open-Topo-Data fallback), compute
Fresnel zone clearance, earth bulge, and knife-edge diffraction loss,
and store the results per QSO.
- terrain_profiles table with migration and TerrainProfile schema
- ElevationClient with batched API calls and fallback
- TerrainAnalysis with Fresnel/diffraction physics (ITU-R P.526-15)
- TerrainProfileWorker on Oban :terrain queue
- QsoWeatherEnqueueWorker enqueues terrain jobs automatically
- QSO show page displays verdict badge and collapsible elevation table
- Reorder show page: terrain, soundings, solar, HRRR, surface obs
- Fix Dockerfile wgrib2 build (add cmake dependency)
HRRR provides hourly 3km-resolution atmospheric profiles, filling the
temporal gaps (12-hourly soundings) and spatial gaps (only 9 sounding
stations) in our current weather data.
- Add hrrr_profiles table and hrrr_queued flag on QSOs
- HrrrClient fetches GRIB2 data via HTTP Range requests + wgrib2
- HrrrFetchWorker derives refractivity/ducting params via SoundingParams
- QsoWeatherEnqueueWorker now also enqueues HRRR jobs
- QSO show page displays HRRR section with collapsible profile
- Dockerfile builds wgrib2 from source for production
Adds haversine_km/4 to Radio context and backfill_distances/1 which
calculates distance_km from pos1/pos2 for QSOs missing it. Called
by QsoWeatherEnqueueWorker before enqueueing weather fetches.
Oban cron worker runs every 4 hours, finds QSOs without weather data,
discovers nearby ASOS/sounding stations, and enqueues WeatherFetchWorker
jobs. Migrations run automatically on app start in production.
