Previously the map loaded the latest cached valid_time from GridCache,
which can be any +Nh forecast hour the worker has written while walking
f00-f18. Users expect to see current conditions on load, not a forecast
that's ~11 hours out.
Corrections to the previous weather-map pass:
* The "helper" that was supposed to live in the top-right was the
color legend, not the layer description. Move the Leaflet legend
control to `topright` (was `bottomright` on desktop).
* Put the layer description back in the desktop sidebar where it
used to live, now with a "Group · Label" header above the body
text so it matches the new style in the mockup.
* Add play/stop controls to the weather forecast timeline, ported
from the propagation map: start plays "now" → end at 1s/step and
loops; stop returns to the time closest to wall clock. A manual
click interrupts playback the same way it does on /map.
* Fix the reconnect/reload loop I introduced by making mount do a
synchronous ProfilesFile read + derive for the full 92k-point
grid. That was pushing mount past the LV socket join timeout on
a cold pod, which makes the LV client fall back to a full HTTP
reload every ~20 seconds (no server-side error). Mount now uses
the original `latest_weather_grid/1` cache-only hot path and only
`weather_grid_at/2` (sync disk read) on user timeline scrubs.
* Clean up the playback timer in the hook's `destroyed` callback.
Two related UI changes driven by the same data:
* Move the selected-layer description out of the sidebar and into a
dedicated top-right overlay on the map. The sidebar kept the same
layer buttons but dropped the descriptive text; the new overlay
shows group + layer name + description in one card. Mobile still
shows the description in the collapsible panel since it has no
top-right free real estate.
* Add a forecast-hour timeline bar at the bottom of the map, matching
the propagation map. WeatherMapLive enumerates ProfilesFile on mount
(the grid worker has been persisting f00..f18 on disk since
commit 07ffcf5), pushes data-valid-times for the JS hook to render
as buttons, and handles a new select_time event by reading the
per-hour ProfilesFile on demand via Weather.weather_grid_at/2.
weather_grid_at/2 deliberately skips the GridCache write path for
non-latest hours — caching 18 × 92k rows would add ~300 MB per pod.
A ~2 MB ETF decode per scrub is fast enough for a click.
Subscribes to propagation:pipeline so the timeline picks up new
forecast hours live as they land, without waiting for the full chain
to finish.
Ports the same two overlay toggles from /map to /weather:
- Maidenhead grid squares via the shared updateGridOverlay helper,
redrawn on moveend when visible.
- ECCC GeoMet WMS radar (CONUS + Canada dBZ), lazy-created on first
toggle with a 6-minute tile refresh timer.
Both toggles live in the desktop sidebar below the layer description
and in the mobile pulldown panel. Hook cleanup clears the radar
refresh timer on destroyed().
Move Scoring Algorithm directly above About in map and weather-map
sidebars; reorder the horizontal nav so Submit sits before Contacts
to match.
Add a "Plot path to beacon" button on the beacon detail page that
navigates to /path with destination, band (snapped via BandResolver),
and dst_height_ft prefilled from the beacon.
Profile page:
* New MicrowavepropWeb.UserProfileLive at /u/:callsign is a public
page showing a user's contacts and beacons. Resolves case-
insensitively so /u/w5isp and /u/W5ISP are the same thing; unknown
callsigns redirect to /. Uses daisyUI card / stats / table
components with an avatar-placeholder initial and hero icons.
* Accounts.get_user_by_callsign/1 (case-insensitive) plus
Radio.list_contacts_for_user/1 and Beacons.list_beacons_for_user/1
back the page. Beacons list includes both approved and pending so
owners see their drafts.
* The top nav bar and the three LiveView sidebars (MapLive,
WeatherMapLive, ContactMapLive) now render the logged-in callsign
as a navigate link to /u/:callsign instead of a static label.
* Nine new tests cover the lookup, the LiveView render, and the
ownership-scoped queries.
Flexible band input:
* New Microwaveprop.Radio.BandResolver module converts any of:
ADIF wavelength labels ("33cm", "1.25cm", "6mm", case/whitespace
insensitive), numeric frequency strings ("903.100", "10368.000"),
and canonical MHz integers into the one of the site's known bands.
Returns the nearest allowed band for numeric inputs >= 900 MHz,
nil otherwise.
* 902 MHz is added to Contact.@allowed_bands, ContactEdit.@allowed_bands,
AdifImport.@allowed_bands, and the BandResolver list so "33cm"
round-trips end-to-end.
* AdifImport and CsvImport now delegate band resolution to
BandResolver, and Radio.create_contact/2 normalizes the :band attr
on the way in so the manual form and any API callers benefit too.
CsvImport's "invalid band" tests previously used 99999 MHz which
the new resolver snaps to the nearest allowed band; swapped to
"notaband" which is truly unresolvable.
Contacts and beacons list UX:
* Remove the "Submitted" column from /contacts — it duplicated info
already visible on the detail page and was pushing the real
columns off narrow viewports. submitted_cell/1 and its three
column-specific tests go with it.
* Hide the Lat / Lon columns from /beacons — six decimal places of
coordinates weren't useful next to the grid square and took a
disproportionate amount of row width.
MRMS
----
Layer the NOAA MRMS PrecipRate product onto the score grid so rain fade
updates every 2 minutes instead of every hour alongside HRRR. New modules:
- Microwaveprop.Weather.MrmsClient: fetches the latest .grib2.gz off the
NCEP mirror (Req auto-decompresses so no gunzip step), writes the raw
GRIB2 to a temp file, and calls the existing wgrib2 wrapper with the
0.125 propagation grid spec to get interpolated cells. Returns a
%{{lat, lon} => mm_per_hour} map with missing-value sentinels dropped.
- Microwaveprop.Weather.MrmsCache: ETS-backed GenServer mirroring
ScoreCache/GridCache. Caches a single "current" entry keyed by
valid_time with PubSub broadcast so peer nodes stay in sync and only
the Oban leader pays the fetch + regrid cost.
- Microwaveprop.Workers.MrmsFetchWorker: cron every 2 minutes, short-
circuits when the cached valid_time already matches the newest file.
Microwaveprop.Propagation.AsosNudge.compute/4 now takes an optional
rain_grid. When a cell has MRMS rain >= 0.1 mm/hr it gets patched onto
the HRRR profile's `precip_mm` field (the scorer already reads it there)
and the cell is re-scored even with no ASOS station nearby. Cells with
MRMS rain below the threshold aren't touched so dry cells keep their
raw HRRR scores (which have the wind/sky/native-gradient signal that
isn't persisted on HrrrProfile rows and would otherwise be lost).
AsosAdjustmentWorker pulls MrmsCache on every tick and passes the grid
through to AsosNudge.compute/4. Also skips the IemClient error branch
that can never happen and handles the ASOS-empty + MRMS-empty case
explicitly. MrmsCache wired into the supervision tree; MrmsFetchWorker
cron entry added to config.exs and dev.exs.
Four new AsosNudge cases cover MRMS-only re-scoring, threshold gating,
and the wet/dry score delta.
Beacons 500
-----------
Beacon.format_freq/1 and format_mw/1 crashed on whole-number floats
(e.g. 24192.0) because `frac == 0.0` could become false under float
rounding while `trim_trailing_zeros/1` stripped the decimal point,
leaving a 1-element list that couldn't be destructured as [_, frac].
Shared format_number/1 helper handles integer input directly and
pattern-matches both the "int-only" and "int + frac" shapes.
Added stream_data property tests covering the whole microwave range for
both integers and floats to catch this class of bug before prod.
UTC clock flash
---------------
The /weather and /map UTC clocks were empty until the JS hook mounted
post-WebSocket, producing a several-second blank spot on initial load
and a clobber risk on sidebar re-renders. Mount now computes a
server-rendered `initial_utc_clock` string and the template seeds the
element with that plus `phx-update="ignore"` so LiveView morphdom won't
overwrite what the hook writes.
Right-hand dark sidebar holds the layer selector, description,
navigation links, and auth menu. Mobile floating panel mirrors the
pattern used on /map so users get the same controls in both views.
- /map now centers on the visitor's Cloudflare geolocation when the
cf-iplatitude/cf-iplongitude headers are present, falling back to DFW.
Initial HRRR score bounds track the chosen center.
- Added /about link to the /map side navigation.
- Renamed "Propagation Map" label to "Propagation Prediction Map" in
the /map page title, sidebars, and the /weather back-link.
- Populated /about with mission, approach, stack, roadmap, and a live
stat grid fed from DB counts (estimates via pg_class.reltuples for
the multi-million-row tables).
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.
