The 'Rover sites' card no longer renders the long list of every site —
each rover-location now appears once as a path-profile group heading,
which carries its own delete button next to the n/m progress text. The
add-site form stays in place.
Adds RoverPlanning.backfill_paths/0 that walks every mission and
re-enqueues RoverPathProfileWorker jobs for any (rover × station) pair
whose Path is missing or not :complete. The path-profile worker
short-circuits on :complete, so this is idempotent.
Wires a new RoverMissionBackfillWorker into both dev (config.exs) and
prod (runtime.exs) crons at HH:30 — heals missions stuck in :pending
or :failed from transient elevation-API errors or interrupted
create_mission enqueues without operator action.
The Stationary-stations summary was rendering whatever the user typed
verbatim ('aa5c 33.1889, -96.4517'). Switch to a pair of helpers that
uppercase the callsign (covering legacy mixed-case rows) and synthesize
a 6-char Maidenhead grid from lat/lon when no grid was stored. Bare
coordinates no longer appear in this list — the grid carries the same
location info in a more amateur-radio-native form.
The path-profile worker now also looks up the propagation grid score for
the path midpoint at the mission's band before flipping status to
:complete, so the row never appears 'done' until both terrain and
propagation prediction have run. The show table renders that score as a
red/yellow/green badge in a new Propagation column.
Each rover-location group heading is now a link to /rover-locations/:id
so the user can jump straight to the spot's detail page from the
mission view.
Path table now shows callsign on top with grid muted below, and the
detail-only Min clearance / Diffraction columns are gone. The verdict
badge matched lowercase 'clear/blocked/marginal' but the worker stores
uppercase 'CLEAR/BLOCKED/FRESNEL_PARTIAL/FRESNEL_MINOR' from
TerrainAnalysis, so every cell silently rendered empty. Updated the
guard clauses to the actual upstream strings and added Fresnel variants.
show.ex (rover-planning) and show.ex (rover-locations) auth + delete
flows go from nested case/case/case to a `with` ladder fed by a single
`authenticated/1` clause that returns `{:ok, user}` or
`{:error, :unauthenticated}`. The else block enumerates the small set
of failure tuples instead of rebuilding nested error returns.
Other idiomatic-Elixir tightening:
- `progress_summary/1` reduces with a `tally_path/2` multi-clause
helper (status as a head pattern, not three Enum.count passes).
- `paths_by_rover_location/1` extracts `group_to_pair/1`,
`station_position/1`, and `group_lat/1` so each transformation is a
pattern match instead of an anonymous fn with `&& fallbacks`.
- `error_summary/1` is two clauses (empty vs populated errors)
instead of a pipe-into-case.
- Drag-to-edit show.ex consolidates the working-coords assigns into
`assign_working_coords/3`.
Bug fix uncovered while writing tests: `add_station` on a fresh
/rover-planning/new form was a visual no-op on the first click —
cast_assoc replaced the unseeded default Station struct with the new
params row instead of appending. Now the initial changeset is built
from `%{"stations" => %{"0" => %{"position" => "0"}}}` so add_station
appends from the get-go. Regression test added at
test/microwaveprop_web/live/rover_planning_live_test.exs.
New test branches:
- form: add_station appends on first click + remove_station drops
the targeted row.
- rover-planning show: add_rover_site whitespace-input rejection,
delete_rover_site permission denial.
- rover-locations show: save_edit rejects unauthenticated drivers.
Suite: 3228 tests, 0 failures. Credo strict: 0 issues.
Owner / admin click "Edit" on /rover-locations/:id and the marker
becomes draggable. As they drag, the JS hook pushes `location_dragged`
events with the new lat/lon; the LiveView updates `working_lat` /
`working_lon` / `grid` so the page shows the live preview without
writing to the DB. "Save" persists via Rover.update_location, "Cancel"
reverts both the assigns and the marker position.
Implementation notes:
- Switched the map marker from L.circleMarker to a draggable L.marker
with a divIcon (CircleMarker has no `dragging` handler).
- A second `draggingDotIcon` (amber, larger, grab cursor) makes the
edit affordance obvious.
- Server <-> hook coordination uses push_event:
set_marker_draggable / reset_marker. Drag results come back on
pushEvent("location_dragged", { lat, lon }).
- Coordinates row binds to working_lat/working_lon so the displayed
decimals + derived grid update on every drag, not only on save.
A new "Rover sites" section between Stationary stations and Path
profiles lists the candidate rover locations the mission scores
against, with:
- An add form that takes the same flexible input as station inputs
(callsign, Maidenhead grid, or `lat,lon`); on submit it creates a
global :good rover-location and re-runs the path matrix.
- A per-row trash button visible to the location's owner / admins
that deletes the location and re-runs the matrix.
`RoverPlanning.candidate_rover_locations/1` is now public so the show
page can list exactly what the worker enqueues against. Add/remove
both call `replace_mission_paths/1` so the matrix stays consistent
with the rover-site set.
Anonymous visitors see a sign-in prompt instead of the form.
When a user types raw "lat,lon" coordinates into a station input,
LocationResolver populates only `lat` / `lon` — `callsign` and `grid`
stay blank. The path-profiles "Station" cell was falling through to
"33.189, -96.452" instead of showing a useful grid.
Now `station_label/1` (display) and `station_endpoint/1` (path-URL
destination) derive a 6-/8-char Maidenhead grid from the stored
lat/lon when no grid is on the row, matching the rest of the page's
grid-first presentation.
`Weather.nearest_native_duct_info/3` returns `{:error, :not_found}`
whenever the midpoint has no native HRRR profile within ±0.07° / ±1 h
— the documented fallback for the sparsely-populated
`hrrr_native_profiles` table (only QSO-worker-touched cells get
ingested). The empty-map fallback was already the right behavior; the
warning was just noise that fired on every /path computation outside
the populated set.
Now the `:not_found` clause silently returns the same fallback shape
without logging.
- Rows in each rover-location group are now phx-click handlers that
navigate to /path with source (rover-loc as 10-char Maidenhead grid),
destination (callsign > grid > coords), band, and rover/station
heights pre-filled — one click takes you to a ready-to-compute Path
Calculator screen.
- Station label now shows "AA5C · EM12kp" when both callsign and grid
resolved, instead of falling back to lat/lon. Bare-grid and
bare-coord stations keep their existing labels.
- Group heading uses Maidenhead.from_latlon(lat, lon, 10) so the
10-char grid is shown in full instead of being truncated to 6
characters.
The flat path table forced you to scan column 1 to mentally group rows
when standing at a specific rover spot. Each rover location now gets
its own card with a heading (grid + lat/lon + notes) and an inner
station-by-station table, so the paths to the fixed stations from the
spot you're at are read in one place.
Sorted by latitude (north → south) so the same location keeps the same
slot across re-renders. `rover_label/1` is removed (its content now
lives in the group heading).
- add_station no longer seeds `"input" => ""` in params, so used_input?/1
treats the new row as untouched and hides the validate_required error
until the user types.
- Show page's format_distance/format_db/format_meters helpers coerce with
`* 1.0` because JSONB returns bare zeros as integers, which crashed
Float.round/2 (FunctionClauseError on /rover-planning/:id render).
- Lat/lon row uses items-start + mt-6 trash so the inputs stay aligned
even when the callsign cell grows from validation feedback.
The hidden 'false' shadow input was rendered after the checkbox, so when
both were submitted the 'false' value overwrote the checkbox 'true' in
the resulting params map. Move the hidden input before the checkbox so
the checked value wins (matching the core_components checkbox pattern).
Adds a full-screen map view rendering every Good rover-location as a
green circle marker (popup links to the detail page). Uses the standard
OSM/Satellite + Maidenhead grid overlay pattern. Bad locations are
excluded. Adds a Map button next to Add location on the index header.
Renames the rover-location status enum and every label that referenced
it. Existing rows are migrated in place. Also touches the consumers:
- Rover.Location enum + default
- RoverLocationsLive index, status filter, form, show, badges
- Rover.Compute and rover_live (only_ideal_locations → only_good_locations)
- RoverPlanning context candidate filter (status == :good)
- RoverPlanning.Show / Form copy
- All rover-related tests
Adds a new globally-scoped, owner-mutable rover-mission tracker:
- /rover-planning paginated table (LiveTable) with View/Edit/Delete
- /rover-planning/new + /:id/edit form: name, band, antenna heights,
notes, "only check against known good locations" toggle (default on),
and a dynamic list of stationary stations entered as callsigns,
Maidenhead grids, or lat,lon pairs (Station changeset geocodes via
LocationResolver, lat/lon stays editable after add)
- /rover-planning/:id show page renders the station list, scope, and a
matrix of computed path profiles (distance, min clearance, diffraction,
verdict) populated as the worker completes each pairing
After save, RoverPlanning enqueues one RoverPathProfileWorker job per
(rover-location × station) pairing. The worker mirrors PathLive's
synchronous compute (ElevationClient + TerrainAnalysis at the mission's
band + heights) and stores the result on the matching path row.
PubSub broadcast on completion lets the show page live-refresh.
Admins can edit/delete any mission; owners can edit their own.
Adds start/end date inputs (UTC) to the sidebar (mobile + desktop) with
Apply dates and Clear buttons. The hook keeps a sliced YYYY-MM-DD on
each line entry so the range check is a string compare during filter
re-application; combines with the callsign filter so e.g. AA5C between
2025-01-01 and 2026-01-01 is one query.
Bare-input phx-change wasn't reliably delivering the value to the
filter_callsign handler. Wrapping the input in a form with phx-submit
+ a Filter button gives explicit submission (Enter or click) on top
of the existing debounced live filter.
Rover.update_location/3 and delete_location/2 now resolve any record
when the actor is_admin. The index + show LiveViews surface Edit/Delete
on every row for admin users, matching the existing owner UX.
Each row now has a View link (and the location cell links too) to a
new show LiveView that renders the full record alongside a Leaflet
map centered on the marker. Owners get a Delete button there as well.
Adds a Maidenhead grid input to the rover-location form. Typing a grid
fills in lat/lon (using square center); editing lat/lon recomputes the
grid at 6-char precision. The phx-change `_target` decides direction so
edits never clobber what the user just typed.
Without the deferral the cron-driven ETS flush GenServer fires every
7.5s alongside Prometheus scrapes, calls PromEx.get_metrics in a Task,
and dies with `Task.await ... time out` (hardcoded 10s) under contention.
Mirrors upstream PromEx.Plug, which calls defer_ets_flush after a
successful render specifically to suppress the cron while scraping is
healthy.
- Extract PathParser.valid_callsign?/1 and reuse from the calibration
Mix task instead of duplicating the regex.
- Document raise behavior on Aprs.recent_packets_with_paths/1 and
Aprs.station_positions/1 (already noted in moduledoc; @doc reinforces
for callers reading the function head).
- Note in the BandConfig guard comment why it sits before the Oban pause
(so a misconfig exits without leaving queues paused).
- Reword the band-mismatched-negatives note as a v1 limitation (no TODO
tag — codebase convention is zero TODOs).
- Print '<computed> / <attempted>' for both positive (HRRR-coverage) and
negative (random-baseline → HRRR) factor compute stages so an operator
can see how much of the corpus survived each filter.
- Guard at task entry: Mix.raise if BandConfig has no 144 MHz entry.
Without it the Recalibrator silently falls back to 10 GHz physics.
- random_baseline now draws from sample_size: max(n, 5_000) so small-n
fits don't cluster geographically.
- Wrap body in try/after Oban.resume_all_queues so iex -S mix workflows
don't leave Oban paused after the task returns.
Pulls verified RF hops from aprs.me's 24h packet retention, computes
factor vectors at each hop's midpoint via the existing Recalibrator,
and runs gradient descent against random-baseline negatives.
Dry-run: prints proposed weights but does NOT mutate band_config.ex.
Refuses to fit on <50 positive or negative samples.
- decode_packet_row no longer guards Decimal.to_float / DateTime.from_naive
with passthrough clauses — Postgrex returns Decimal for numeric and
NaiveDateTime for timestamp without time zone, so the WHERE clause
filters out the only path that could have hit the alternate branches.
- recent_packets_with_paths shifts :since to UTC before to_naive so a
caller passing a non-UTC %DateTime{} doesn't silently match the wrong
window.
- moduledoc now documents that the module raises on connection/SQL
errors and is unsafe in async contexts without a catch.
Q-construct now matches the explicit APRS-IS set (qAC/qAX/qAU/qAo/qAO/
qAS/qAr/qAR/qAZ/qAI) instead of any qA[A-Za-z]. WIDE/TRACE n-N now allows
n and N up to 7 per the APRS New-N paradigm (was [12]).
Three spec-compliance fixes to PathParser:
1. Q-construct regex now accepts lowercase letters (qAo, qAr, etc.).
The moduledoc lists qAo as a Q-construct to skip but the previous
~r/^qA[A-Z]$/ rejected it, leaving it to be misclassified.
2. self_loop?/2 now compares callsigns only; the spurious
src_pos == dst_pos clause would falsely suppress two distinct
stations that happen to share coarse coordinates (e.g. same building).
3. Strengthen the "lookup returned nil → drop hop, do NOT advance source"
test: extend the path to three tokens so the assertion actually proves
the third hop chains from the previous good source rather than from
the dropped one. The two-token version passed regardless of behavior.
Self-loop fixture updated to trigger via callsign equality (the only
remaining mechanism) instead of position equality.
Pure-Elixir parser that walks an APRS digipeater path left-to-right and
emits verified hops for callsigns carrying the used flag (`*`). Filters
Q-constructs, TCPIP/TCPXX, and routing aliases (WIDE/TRACE/RELAY/etc.);
handles anonymous-digi cases, missing station-position lookups, and
self-loops without advancing source past unattributable hops.
Used by upcoming 144 MHz calibration to attribute aprs.me receives to
real digipeater geometry without persisting any APRS data on our side.
Wire up Microwaveprop.AprsRepo as an optional secondary Ecto repo that
points at the sister aprs.me Postgres for read-only access. This is the
foundation for upcoming 144 MHz calibration work that uses verified APRS
RF hops as ground truth.
* lib/microwaveprop/aprs_repo.ex declares a read_only repo; no schemas,
no migrations, no writes — Microwaveprop never persists APRS data.
* Application supervisor starts the repo only when configured (dev/test
via config blocks, prod via APRS_DATABASE_URL). A missing config logs
a warning and skips startup so the main app still boots.
* config/dev.exs + config/test.exs add local aprsme_dev / aprsme_test
endpoints. Test pool uses Ecto SQL Sandbox; tests that don't touch
APRS data don't need to check the connection out.
* config/runtime.exs guards the prod block on APRS_DATABASE_URL —
unset env logs a warning and leaves the repo unconfigured.
/map's PropagationMap hook pushes `map_bounds` on every moveend/zoomend.
When a user live-navigates from /map to /weather, an in-flight bounds
push can land on the new WeatherMapLive (the same LV channel survives
the navigation), and WeatherMapLive's `handle_event/3` had no clause
for it — the LV process crashed with FunctionClauseError, taking the
user's session down.
WeatherMapLive doesn't need viewport bounds — the /weather/cells HTTP
endpoint reads them off the URL the client builds — so the safe fix is
a no-op handler. Tested.
Past minute 30 of the wall clock the next forecast hour is closer to
utc_now() than the current hour, so the picker would land on (e.g.)
19:00Z when the user is at 18:43Z. HRRR has 19:00Z, but the HRDPS
chain only seeds the *current* hour (18:00Z), so the dual-source map
showed an empty Canadian half whenever we crossed the half-hour mark.
Switch to "most-recent valid_time <= now", with a fallback to the
closest future when nothing on disk is yet at-or-before now (cold
start). Hoist the picker into a public function so it can be unit-
tested deterministically — anchoring the integration test on
DateTime.utc_now() truncated to the hour would have only verified the
new behavior past minute 30.
/weather-ca delegates to the same picker so the two maps agree on
"current."
The /weather dual-source timeline picks times from HRRR's hourly
cadence, but HRDPS publishes 4×/day with multi-hour latency, so the
requested time almost never has an exact HRDPS dir on disk. The
controller was returning empty rows for HRDPS, leaving the Canadian
half of the map blank.
Snap to the closest HRDPS valid_time within a 6h window. /weather-ca
keeps exact-time semantics in practice because its timeline is built
from HRDPS-only listings, so the nearest is always the same time.
The 1-hour valid_time filter inherited from /weather is wrong for
HRDPS: the model publishes 4x/day with 3-4h publication latency and
the chain step adds ~13 min on top, so the freshest data on disk is
routinely 4-6h old. With the 1h cutoff in place, /weather-ca's
timeline was empty whenever there wasn't an active chain step running,
which left the JS hook with nothing to fetch. The sidebar already
shows the selected valid_time prominently — users can see for
themselves how stale the data is and don't need the page to hide it.
Recalibrator and FrontalAnalysis use Nx for tensor math, but Nx is
declared `only: [:dev, :test]` in mix.exs because neither module has a
prod entry point — Recalibrator is invoked by hand from IEx and
FrontalAnalysis is research scaffolding. The prod compile would emit
"Nx.to_number/1 is undefined" warnings on every Nx call. Add a
`@compile {:no_warn_undefined, Nx}` directive to both modules so the
prod build is clean without dragging Nx/Axon/EXLA (~hundreds of MB) into
the runtime image.
New LiveView at /weather-ca duplicates the /weather UI but defaults the
viewport to central Canada (55N, -100W, z=4) and renders the map div
with data-source="hrdps". The JS hook reads that attribute and appends
&source=hrdps to every cell fetch; the WeatherTileController routes
those reads through Weather.weather_grid_hrdps_at/2, which only reads
the <vt>.hrdps scalar dir and skips HRRR merging entirely. Timeline is
sourced from ScalarFile.list_valid_times_hrdps/0 so HRDPS-only hours
show up even when no HRRR file exists for the same valid_time.
Also drops "— Unified" from the algo.md H1.
The HRDPS pipeline as written was unusable in production: each chain
step took ~5 hours (not 30-90s as the dev-bench claim) because every
`wgrib2 -lon` batch redundantly JPEG2000-decodes ~150 records. With 57
batches × 18 forecast hours, a single cycle would take days to drain.
The /weather Canadian view only needs the current hour, so the cheapest
fix is to stop seeding the rest of the chain entirely:
* Rust grid: HRDPS_STEP=0.5 (was 0.125) drops point count 16× to ~3.5k.
Coarser cells than HRRR, but /weather gets visible Canadian coverage
inside one chain step (~20 min) instead of never.
* GridTaskEnqueuer.seed_current_hour/2 inserts exactly one forecast row
whose valid_time is closest to `now`. fh is clamped to 1..18 so the
Rust F00Reserved branch never fires.
* HrdpsGridWorker switches to seed_current_hour and drops the
6-hour-cycle cron in favor of HH:35 hourly fires. Reseeds are
idempotent on the 4-column unique key.
Also fixes a pre-existing credo "nested too deep" in
ScalarFile.read_point by extracting lookup_in_chunk + hit_or_false
helpers — happened to be on the read path that surfaces this work, so
folding it into the same commit.
Adds lat/lon/zoom URL params to /weather so reload / share-link
restores the exact map state. The existing ?layer= param keeps
working alongside.
LiveView side:
- mount() reads lat/lon/zoom from query params, clamps to valid
ranges (lat -90..90, lon -180..180, zoom 4..10), and falls back
to DFW@z7 when missing or invalid. Initial values flow to the
hook via three new data attributes.
- handle_event("viewport_changed", ...) accepts {lat, lon, zoom}
pushed by the hook on debounced moveend, clamps + rounds, and
push_patches the URL with replace: true so browser history
doesn't grow an entry per pan tick.
- build_path/2 helper centralises URL construction so select_layer
and viewport_changed both produce a deterministic param order
(layer, lat, lon, zoom). Tests assert exact URLs.
JS hook side:
- mounted() reads data-initial-lat/lon/zoom from the el dataset
with parseFloat/parseInt + Number.isFinite gates, then seeds
Leaflet's center/zoom from those instead of the previous
hardcoded (32.897, -97.038, 7).
- moveend handler now also schedules a 400 ms-debounced
pushEvent("viewport_changed", {lat, lon, zoom}) so the URL
catches up with whatever the user panned/zoomed to. Separate
debounce timer from the cells fetch since the URL push and the
network fetch have different cadence sweet spots.
Tests cover: initial seeding from URL params, clamping of bad
values, viewport_changed event producing the right patched URL,
and the original layer-shareability test (now expecting the full
viewport in the URL).
The /weather map now shows HRRR-derived data wherever HRRR has
coverage and falls back to HRDPS-derived data for Canadian cells
outside HRRR's bbox. North of the 49°N HRRR-coverage line the map
stays populated instead of going blank.
Rust:
- weather_scalar_file::dir_for_hrdps + write_atomic_hrdps land HRDPS
scalar chunks at `<vt>.hrdps/` so HRRR's `<vt>/` write isn't
clobbered. The HRRR writer wipes its dir before each write — both
sources need their own dir to coexist.
- pipeline::run_chain_step_hrdps now derives a ScalarRow for each
scored cell (same derive_row that HRRR uses; same wire format) and
writes them via write_atomic_hrdps alongside the .hrdps.prop score
files.
Elixir:
- ScalarFile.dir_for_hrdps + read_bounds + read_point + exists? all
walk both `<vt>/` (HRRR) and `<vt>.hrdps/` (HRDPS). read_bounds
concatenates with HRRR-precedence on overlap (defensive — Rust
pipeline doesn't write HRRR-overlap cells, but cheap to enforce).
- Weather.weather_grid_at unchanged: it routes through ScalarFile,
which now transparently returns the union. GridCache stays
per-valid_time so a single cache entry holds both regions.
Tests cover four scenarios: HRRR-only, HRDPS-only, both-present
union, and HRRR-precedence on the same cell.
Stages 6, 7, 10 of the HRDPS plan, plus the Elixir read-side merge
that makes Rust's `.hrdps.prop` writes show up on /map.
Read side:
- `ScoresFile.path_for_hrdps/2` + `read_hrdps/2` — companions to the
HRRR equivalents. Same decode path; different filename.
- `ScoresFile.read_bounds/3` now reads HRRR + HRDPS files and
concatenates the cells. Files are disjoint by construction
(Grid.hrdps_only_points excludes CONUS) so no de-dup needed.
- `ScoresFile.read_point/4` checks `.prop`, then `.hrdps.prop`, then
legacy `.ntms` — first hit wins. Cells outside their owning region
read as no-data in the other file's grid, so the order doesn't
matter for correctness.
- `Propagation.warm_cache_and_broadcast/2` reads both files and
merges before broadcasting to the cluster ScoreCache. A single
missing file (HRDPS pre-cycle, HRRR briefly absent) is now OK —
the cache warms with whichever side is available.
Activation:
- runtime.exs cron: HRDPS seed worker fires at HH:35 of each cycle
hour (05:35Z, 11:35Z, 17:35Z, 23:35Z) — 5h after cycle, 30 min
staggered from HRRR's */15 schedule.
- HrdpsGridWorker moduledoc updated: no longer dormant; Rust
prop-grid-rs handles source='hrdps' rows.
- map_live North America bbox extended to (24.5, 60.0, -141.0, -52.0)
for the out-of-coverage banner check; visitors anywhere in CONUS
or the Canadian extent now stay banner-free.
Cleanup:
- mix hrdps.probe deleted — its risks are retired and the production
HrdpsClient covers the same surface.
What's still in motion (not blocking the Canadian /map):
- Per-valid_time profile + scalar artifacts for HRDPS (would let
/weather show Canadian temperature/refractivity layers). Rust
pipeline currently skips those so the HRRR-written companion files
aren't clobbered — separate stage when /weather UX is decided.
- FreshnessMonitor HRDPS staleness tracking — HRDPS has its own cron
and a different cadence than HRRR; HRRR-stale logic doesn't apply
cleanly. Defer until prod tells us what alarms we actually want.
Stage 3 (Elixir foundation) of the HRDPS plan. Lands the scaffolding
that lets the Rust prop-grid-rs HRDPS branch be wired up cleanly when
it ships, without further DB or Elixir-side changes.
What ships:
- `grid_tasks.source` column (default 'hrrr', backfill is a no-op).
Replaces the (run_time, forecast_hour, kind) unique index with a
4-column key (..., source) so HRRR and HRDPS analysis/forecast rows
for the same cycle coexist.
- `Grid.hrdps_only_points/0` — Canadian cells inside HRDPS bbox
(49-60°N, -141 to -52°W) but outside HRRR's CONUS bbox. Disjoint
from `conus_points/0` by construction so the two grids never
double-write the same (lat, lon).
- `Grid.point_source/1` — `:hrrr | :hrdps | :neither` classification
for a (lat, lon) pair. Routes per-QSO enrichment to the right NWP
source.
- `GridTaskEnqueuer.seed_with_analysis/2` and `seed/2` accept a
`:source` option; defaults to "hrrr" so existing callers are
unchanged.
- `HrdpsGridWorker` cycle seeder mirroring PropagationGridWorker's
shape but for HRDPS's 4×/day cadence. `:hrdps` queue added to base
Oban config.
What's deferred:
- The Rust `prop-grid-rs` worker doesn't yet branch on
`task.source`. Until that ships, `HrdpsGridWorker` stays out of
runtime.exs cron — it would just produce rows that the Rust worker
mishandles as HRRR. Module doc explicitly notes the dormant state.
- Map overlay extension and FreshnessMonitor HRDPS staleness deferred
to follow-up sessions once real data flows.
Activation path documented in the updated plan file.
Coverage cap recorded as Stage 8 decision: 60°N for v1 (SRTM stops
there). Arctic CDEM deferred to a follow-up plan.
Stage 2 of the HRDPS plan. Mirror of hrrr_profiles for HRDPS-derived
rows so HRDPS can be dropped/reprocessed without disturbing the 4500+
HRRR profiles already in prod. Same column set, same indexes,
PARTITION BY RANGE (valid_time) with quarterly partitions starting at
the deploy quarter.
Schema follows the @primary_key {:id, :binary_id, autogenerate: true}
convention and the same set of derived fields HrrrProfile carries
(surface_refractivity, min_refractivity_gradient, ducting_detected,
duct_characteristics, etc.) so the rest of the pipeline can consume
HRDPS-derived rows interchangeably with HRRR-derived rows.
Unique constraint on (lat, lon, valid_time) is enforced at the DB
level via the partitioned index; schema-level unique_constraint/2
matching against changeset errors doesn't apply because the
partition's index name varies per partition. Production upserts go
through `on_conflict: {:replace_all_except, ...}` per project
convention.
Stage 1 of the HRDPS plan. Mirrors HrrrClient.fetch_grid/3's signature
so PropagationGridWorker can call either polymorphically.
Architectural shape per the probe wedge findings:
- ECCC's date-prefixed datamart URL structure
(dd.weather.gc.ca/{YYYYMMDD}/WXO-DD/model_hrdps/...)
- One-variable-per-file model — fetch ~14 small GRIB2s concurrently,
byte-concatenate into a single multi-record binary, hand to
Wgrib2.extract_points_from_file. wgrib2 reads multi-record files
natively so no -merge step is needed.
- wgrib2's -lon flag handles the rotated-lat/lon reprojection
internally — no manual rotation math.
Variable catalog covers the surface set the propagation scorer reads
plus the 1000-700 mb pressure-level set used by the refractivity
gradient. PWAT is unavailable in HRDPS f000 inventory; the scorer's
PWAT factor will fall back to its default for HRDPS-derived points.
DEPR (T-Td depression) is treated as an alternate primary; when DPT
is absent build_profile_from_extracted derives dewpoint as
temp - depression so downstream consumers see the same shape as HRRR.
Plan task 1.6 (CYYR projection sanity check vs UWYO sounding) is
covered by the live probe at lib/mix/tasks/hrdps_probe.ex which
already validated wgrib2's rotated-grid handling against five
Canadian cities; the production implementation routes through the
same Wgrib2.extract_points_from_file path that the probe used.
Adds mix hrdps.probe — throwaway wedge that retires URL/projection/decode
risks against MSC Datamart. Verified against five Canadian cities with
plausible 2m temperatures via wgrib2's native rotated-lat/lon support.
Findings update what we knew:
- ECCC reorganized to date-prefixed paths; the old /model_hrdps/ root
404s now. Real URL is dd.weather.gc.ca/{YYYYMMDD}/WXO-DD/model_hrdps/...
- HRDPS publishes one variable per GRIB2 file (~3.5 MB each), not
HRRR's bundled wrfsfcf format. ~14 files per cycle/forecast hour.
- wgrib2 -lon LON LAT handles the rotated grid natively — no manual
reprojection math needed.
New plan at 2026-04-29-hrdps-canadian-prop-grid.md supersedes the
2026-04-13 one (which assumed HRRR-style idx + byte-range fetches that
don't apply). Probe deletion is a Stage 10 step in the new plan.
