Read-side cutover for the binary scores store and a companion
cleanup that removes the biggest remaining DB write from the hot
path.
Propagation.scores_at/3, available_valid_times/1, latest_valid_time/0,
latest_valid_time/1, earliest_valid_time/1, point_detail/4, and
point_forecast/3 all now prefer ScoresFile and fall back to the
propagation_scores table when a file is missing. The map render
path reads from /data/scores first; Postgres stays as a safety
net while dual-write is on. point_detail still pulls factors from
Postgres (analysis-hour rows only) and coalesces nil to an empty
map so the JS popup iterates cleanly.
replace_scores/2 is now gated by a postgres_writes_enabled? flag
(runtime env MICROWAVEPROP_SCORES_POSTGRES=false, or the
:propagation_scores_postgres app env key) so the binary-only path
can be benchmarked locally without the DB insert. Default stays
true.
PropagationGridWorker no longer calls store_hrrr_profiles —
persisting 92k grid rows × 19 forecast hours of JSONB profiles
was ~12 min of wall time per chain for a table only
AsosAdjustmentWorker read from. Per-contact HRRR enrichment
through HrrrFetchWorker still writes its own (is_grid_point:
false) rows. AsosAdjustmentWorker is disabled in all three cron
configs since its data source is gone.
DataCase resets the scores tree between tests so per-test
ScoresFile writes don't leak across cases, and ScoresFileTest
switches to async: false because it mutates the global
:propagation_scores_dir env.
IEM's RAOB endpoint stopped keeping Canadian stations current — most
stalled around Sep 2024 — which leaves a gap in refractivity/ducting
calibration over all the CW*/CY* stations already in weather_stations.
MSC's own tephi CSV is fixed-width and rendering-focused; the WMO TEMP
bulletins would need a full decoder. University of Wyoming serves the
same stations in a clean space-delimited format, is current, and
accepts the 3-letter station code (drop the leading C from Canadian
ICAO). Its output shape matches IemClient.parse_raob_json/1 exactly,
so it drops straight into Weather.upsert_sounding/2.
- New UwyoSoundingClient with URL builder, Req-based fetch_sounding,
and a fixed-width parse_sounding_html that extracts PRES/HGHT/TEMP/
DWPT/DRCT/SKNT from the <PRE> block and DateTime from the <H2> header.
- New CanadianSoundingFetchWorker: Oban batch worker that finds all
sounding stations whose code starts with C, picks the most recently
publishable 00Z or 12Z slot (90 min publish delay), calls UWYO per
station, and upserts with SoundingParams-derived refractivity/
ducting fields.
- Oban cron at 01:30Z and 13:30Z (dev + prod) to drive the worker.
- Req.Test plug wiring in config/test.exs.
- Captured Goose Bay fixture as test/support/fixtures/uwyo_sounding_yyr.html.
Also drops two implementation plans under docs/plans/:
- 2026-04-13-rdps-vertical-profiles.md: ~2 day plan for RDPS 10 km
Canadian ducting outside HRRR's Lambert footprint.
- 2026-04-13-hrdps-canadian-prop-grid.md: ~5 day plan for the full
HRDPS 2.5 km Canadian prop grid. Explicitly recommends doing RDPS
first.
TDD throughout, 19 new tests, 1318/1318 passing, credo strict clean.
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
Height in feet doesn't need decimal precision. Migrates the DB
column, updates schema type, and strips trailing .0 from form
input so the integer cast succeeds.
- Rename beacons.height_m to height_ft; migration converts existing
values (m * 3.28084). Form/list/show labels updated.
- Beacon changeset now fills lat/lon from the grid when they're blank
(previously only the reverse worked). Lat/lon and grid inputs are no
longer marked required in the form — enter one side and the other
populates on blur via phx-change.
- Rename beacons.power_watts to power_mw (migration multiplies existing
values by 1000); form/list/show all relabeled to "Power (mW)"
- Fix Add-monitor button alignment on /users/settings by rendering the
label above and putting the input and button in a plain flex row so
the input wrapper margin no longer offsets the button
- Extend the settings page re-auth window from 10 minutes to 24 hours
Beacons:
- Scaffolded with phx.gen.live then reworked so reads are public
and mutations go through a live_session gated by the new
:require_admin on_mount hook in UserAuth
- Beacon schema stores frequency (MHz), callsign, grid, lat/lon,
power (W), and height above ground (m); grid auto-derives from
lat/lon when left blank via Maidenhead.from_latlon
- Adds Maidenhead.from_latlon/3 so we can compute grids locally
instead of hitting an external API
Users admin page:
- /users and /users/:id/edit (admin-only) for listing, editing
(callsign/name/email/is_admin), and deleting other users
- Adds Accounts.list_users, admin_update_user, delete_user, and
a dedicated admin_changeset on the User schema
- Nav gains a "Users" link for admins and a "Beacons" link for
everyone
Generated Accounts context, User schema, and controllers via
phx.gen.auth. Adapted it for password-only login with required
email confirmation:
- Users have callsign (unique, uppercased), name, email, password
- Registration form fields: callsign, name, email, password, confirm
- Magic-link login path removed; login is email + password only
- After register, a confirmation email is sent and login is blocked
until the account is confirmed via the token URL
- Confirmation link logs the user in on first use
- SMTP2GO configured as the outgoing mailer in k8s prod
