Adds an Atmospheric Profile section to the link calculator that shows
the HRRR data actually feeding the prediction: valid/run time, a
per-point table (src/mid/dst) with surface temp, dewpoint, pressure,
HPBL, PWAT, surface refractivity and dN/dh, plus a skew-T log-P chart
for the midpoint vertical profile.
Pulls the skew-T chart function out of contact_live into a shared
component so both LiveViews can render it without duplication.
Historical contacts showed a skew-T log-P diagram that stopped at 700 mb
because HrrrClient and Era5Client only fetched pressure-level data down
to the top of the boundary layer. The chart canvas already ran up to
100 mb, so the trace clipped mid-atmosphere.
Two complementary fixes:
1. Extend @pressure_levels in HrrrClient and Era5Client with
650/600/550/500/450/400/350/300/250/200/150/100 mb so new fetches
cover the full troposphere + lower stratosphere.
2. Prefer the native hybrid-sigma profile for the contact-detail
skew-T when one has been backfilled for the contact's hour. The
native profile already stores all 50 hybrid levels up to ~19 km,
so historical contacts covered by the native backfill get a full
trace without re-hitting S3. A new HrrrNativeProfile.to_skew_t_profile/1
converts the parallel arrays into the %{"pres","tmpc","dwpc","hght"}
list shape the renderer expects, deriving dewpoint from SPFH via the
Magnus inverse. Weather.find_nearest_native_profile/3 mirrors
find_nearest_hrrr/3 for the lookup.
The atmospheric profile header was a single-line flex row with no
wrap, so on narrower viewports the HRRR (3 km) badge and the unit
suffixes were breaking mid-phrase — the badge showed "HRRR (3 /
km)" with borders crossing through the text. Add flex-wrap plus
whitespace-nowrap on each cell so the whole row wraps cleanly
onto a second line instead of shrinking each cell vertically.
Render the HRRR pressure-level profile as a full skew-T log-P
diagram on the contact detail page: skewed isotherms, isobars,
dry adiabats, saturation mixing ratio lines, plus the T and Td
traces. Math lives in MicrowavepropWeb.SkewT (Magnus formula,
dry adiabat potential temperature, log-P projection) and is
exercised by a dedicated test module. The atmospheric profile
section now expands by default so the chart is visible without
an extra click.
Contact detail page now renders an atmospheric profile section backed by
HRRR when available and ERA5 (reanalysis) otherwise, labeled with the
data source. When both sources are missing and HRRR is known-unavailable
(pre-2014 contacts), the Era5FetchWorker is enqueued so the month-tile
backfill gets triggered from a user visit.
Status page ERA5 progress previously computed "complete" as
(total_contacts - hrrr_unavailable_contacts), which treated every contact
with any HRRR status as ERA5-complete — inflating the bar to 76% while
era5_profiles had 0 rows. Replaced with a per-candidate EXISTS query
against era5_profiles using the same 0.15°/30-min tolerance
Weather.find_nearest_era5/3 uses at lookup time.
Adds an "Open in Path Calculator" action to the contact detail
header. The link navigates to /path with source/destination prefilled
(preferring Maidenhead grids over station callsigns, since grids
are exact and callsigns go through a QRZ + geocoder round-trip)
and the contact's band selected. PathLive's handle_params already
auto-runs the calculation when source + destination are present,
so the user lands straight on the computed path ready to tweak
TX power, antenna heights, and gains.
TerrainAnalysis.analyse was being called with default 0 m antenna
heights on both ends of a QSO's path, which makes the knife-edge
diffraction math pretend the radios are sitting directly on the
terrain surface. Pass 3.048 m (10 ft) for both ant_ht_a and ant_ht_b,
and shift the forward/reverse elevation angles to match. This is
only a display assumption on /contacts/:id — terrain worker paths
computed elsewhere are unaffected.
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.
Adds Microwaveprop.Propagation.AsosNudge: a pure IDW bias-field module
that takes ASOS observations + HRRR profiles and returns re-scored grid
rows for every cell within 250km of a reporting station. Upper-air
fields (min_refractivity_gradient, pwat_mm, hpbl_m, profile, duct
metadata) pass through unchanged so HRRR's signal isn't clobbered.
The old AsosAdjustmentWorker was unwired and buggy — nil'd out ~22% of
the scoring weight and wrote orphan timestamps. Replaced with a slim
worker that queries the latest HRRR valid_time, fetches live ASOS
currents, calls AsosNudge.compute/3, and upserts onto
(lat, lon, valid_time, band_mhz) so nudged values overwrite the HRRR
hour cleanly instead of polluting available_valid_times. After each
upsert it warms ScoreCache and broadcasts propagation:updated so live
/map clients refresh.
Cron hooked up every 10 minutes in config.exs and dev.exs. Also cleaned
up the stale "dev has propagation disabled" note in CLAUDE.md.
13 new AsosNudge unit tests cover: residual computation (co-located,
out-of-grid, nil fields), IDW weighting (single station, far station,
two equidistant stations, nil component handling), upper-air
preservation, and the compute/3 entry point's shape and radius filter.
Drive-by Styler formatting touched a handful of unrelated files from
`mix format`.
The contact detail page used to gather every enrichment source in one
parallel_hydrate/2 bundle and await all five tasks before updating any
assigns, so users watched the whole right-hand column flash in at the
speed of the slowest query (usually hrrr_profiles_for_path against a
42M-row table).
Each source now runs in its own start_async task: :weather, :solar,
:hrrr_path, :terrain, :iemre. Matching handle_async/3 clauses assign
the slot and call refresh_computed/1, which rebuilds elevation_profile
+ propagation_analysis + data_sources from whatever's currently in
assigns. Sections appear independently as their data arrives, and the
existing PubSub handlers (:hrrr_ready, :weather_ready, :terrain_ready,
:solar_ready) still pick up later backfill completions the same way
they did before.
- 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 Weather.GridCache: ETS cache of derived HRRR grid rows keyed by
valid_time, cluster-synced via PubSub. Eagerly warmed from
PropagationGridWorker after each upsert so /weather map pan/zoom and
weather_point_detail hit zero DB on warm cache.
- Replace latest_weather_grid DB query path with cache-first lookup +
DB fallback. hrrr_profiles is 42M rows partitioned; pulling 3-10k
rows per viewport on every pan was the main cost.
- ContactLive.Show: defer the heavy enrichment loads (weather, solar,
HRRR, terrain, IEMRE, elevation profile, ITU-R propagation analysis,
data_sources) into a handle_info(:hydrate) that runs after the shell
renders. Initial mount now returns nil placeholders; template already
had :if guards for all of them. Shell-to-first-paint goes from
~500ms-2s down to ~20ms.
- Cache fetch_queue_counts for 5s in ContactLive.Show — oban_jobs group
by query was running on every contact page view.
- Backfill stats: wrap count_unprocessed, fetch_stats, fetch_db_stats
in Microwaveprop.Cache with 2-5s TTLs; bump refresh debounce from 1s
to 2s so bulk enrichment events don't thrash the DB.
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
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.
Terrain elevations now include the earth bulge correction, so the
profile visually humps up in the middle relative to the straight
LOS beam — showing how the curved earth rises into the signal path.
Uses actual k-factor from HRRR refractivity when available, otherwise
standard 4/3. For a 300 km path at k=4/3, the midpoint bulge is
~2,650 m (8,700 ft).
- Register/Log in (or callsign/Settings/Log out) now live next to
the Map/Path/Rover links in the main header instead of a separate
top menu bar
- Add on_mount in UserAuth to assign current_scope on LiveView mount,
and pass current_scope through to Layouts.app from every LiveView
- Drop the old top <ul> from root.html.heex
- Password minimum lowered from 12 to 8 characters
Contact scoring now uses all HRRR profiles along the path instead of
just pos1. Aggregation strategy:
- Best along path for beneficial factors (refractivity, pressure)
- Worst along path for harmful factors (rain, wind)
- Average for neutral factors (temp, dewpoint, PWAT, BL depth)
Scorer.path_integrated_conditions/2 merges multiple profiles into a
single conditions map. Falls back gracefully to single-profile scoring
when only one profile is available.
Removed n_live_tup > 0 filter that hid tables when pg_stats reports 0 rows
during VACUUM. Added dead tuple column with warning highlight to monitor
vacuum progress. Also includes Styler reformatting and unused dep cleanup.

Previously, if a job was cancelled or lost while status was :queued,
viewing the contact detail page would not re-enqueue. Now HRRR,
weather/soundings, and terrain all re-enqueue when :queued with no
data, relying on Oban uniqueness for deduplication.
Shows provenance of all data used in the analysis:
- HRRR: path profile count, pressure levels, valid time, grid point
- Elevation: sample count, path distance, source (SRTM), duct layers
- Terrain: sample count, verdict, max elevation, diffraction loss
- Surface observations: station count and time range
- Soundings: profile count, stations, levels, ducting detection
- Solar indices: SFI, SSN, Ap
- 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
- WeatherFetchWorker broadcasts on ASOS and RAOB completion
- Contact show page subscribes and reloads weather data on receipt
- Loading spinners for soundings and surface observations when queued
- Propagation analysis recomputed with new sounding duct data
- HRRR and terrain workers broadcast via PubSub on completion
