Adds Microwaveprop.Radio.TextSanitizer to remove BOM, zero-width
spaces/joiners, C0 control bytes (except CR/LF/TAB), and DEL, and to
collapse NBSP and other unicode whitespace into a regular space.
CSV: applied to the whole upload at the top of preview/2.
ADIF: applied per-field-value after extraction so the byte-counted
length tags still slice the right substring.
New globally-shared list of rover-friendly (or off-limits) parking
spots. Anyone can view; logged-in users can add new locations and
edit/delete their own. Each location stores lat/lon, free-text notes,
and a status enum (:ideal | :off_limits).
* Microwaveprop.Rover.Location schema + migration
* Rover.list_locations/0, create_location/2, update_location/3,
delete_location/2 (mutations require User; ownership-scoped)
* /rover-locations LiveView in the public live_session — Add button
is disabled for anonymous visitors, Edit/Delete buttons render
only on the user's own entries
* Tests for context + LiveView covering anonymous read, owner-only
edit/delete, and form submission
Adds Microwaveprop.Canopy module that reads 1° × 1° uint8 per-degree
canopy-height tiles (mirrors SRTM .hgt naming/layout, 30 m resolution).
Returns 0 m for areas with no tile on disk so the lookup is safe to
thread through the existing path-clearance pipeline before any data
lands.
Wires canopy into:
- PathTerrain.obstacle_top: per-sample blocker = ground +
max(building_m, canopy_m), so the rover ranks paths through forests
as obstructed even when no buildings sit on the line
- CandidateDetail profile: each sample now carries canopy_m alongside
building_m
- Rover-detail SVG: green "trees" polygon stacked on terrain, under
the red building polygon
- Path calculator elevation chart: green Tree Canopy dataset between
terrain and buildings
Data prep (download Potapov 2019 / Lang 2022 GeoTIFF, slice to per-degree
uint8 tiles, drop in /data/canopy/) is a separate one-shot operation —
without tiles, lookups return 0 and the existing behavior is unchanged.
Compute.run now accepts a `progress` callback and reports human-readable
labels before each pipeline step (loading grid, looking up elevation,
checking road access, scoring cells, etc.). RoverLive feeds it via
send/2 to itself and renders the latest label as small text to the left
of the Calculate button while it's running.
Adds a per-cell building-clutter penalty so the algorithm down-ranks
spots in built environments where buildings on multiple sides
scatter/block signal regardless of which station you're aiming at.
Penalty = max_height_within_75m / 5 dB, capped at 6 dB. Path-clearance
already accounts for buildings ON the link path; this is the
"surrounded by stuff" signal.
Phase 2/3/5 of the building-blockage support:
* Parser streams csv.gz tiles into compact records (centroid, radius,
height) — keeps RAM ~32 B per polygon, drops -1.0-height entries.
* Index buckets records into 0.01° (~1 km) grid cells in a public ETS
table for concurrent reads; max_height_near/3 and records_near/3
scan only the 9 nearest buckets.
* Loader lazily parses any cached quadkey before a Calculate so the
scorer is terrain-only when tiles aren't on disk yet.
* Rover.PathTerrain now treats each path-sample obstacle as
terrain_elev + max_local_building_height, so blocked LOS through
recent construction actually reduces clearance.
* Selecting a candidate pushes a candidate_buildings event with the
buildings near each rover→station path; the hook renders them as
height-coloured circles (yellow <10 m, orange 10-30 m, red >=30 m)
with a tooltip showing height in meters.
Phase 1 of building-blockage support: implements quadkey math (Bing/MS
tile encoding), looks up the MS dataset-links index for UnitedStates,
and downloads csv.gz quadkey tiles to /data/buildings (overridable via
:buildings_cache_dir). Index is cached 24h; tiles are written once and
reused. No path-analysis wiring yet — that's the next slice.
- Local prominence: each cell's elevation vs. its 8-neighbor ring
(~1.3 km radius) feeds a small additive bonus so broad hilltops
rank above isolated SRTM voxels
- Road proximity: one Overpass call per Calculate fetches drivable
ways inside the bbox; cells beyond ~0.5 km of any road get a
light dB penalty, gated off in tests
For each (rover cell, fixed station) pair, sample SRTM along the
great-circle path and add a per-link dB bonus proportional to the
rover's elevation above the highest intermediate terrain. Rover spots
on hilltops with clear sight to multiple stations now rise to the top.
Also vendor Leaflet's layers control PNGs and copy them under
priv/static/assets/css/images/ on build so /rover stops 404'ing on
layers-2x.png.
The grid-cached profile is trimmed to 13 levels (1000→700 mb) for
memory reasons, so the skew-T plot showed nothing above 700 mb.
HrrrClient.fetch_profile/4 now accepts a forecast_hour opt; SkewtLive
issues a per-point fetch against the same cycle the cached row came
from to get the full 1000→100 mb set, falling back to the cached
truncated cell on any failure.
Time selection no longer round-trips through the URL — `select_time`
updates state in-process and triggers a focused :load_skewt_time
async, so refreshing or sharing a /skewt?q=... link always lands on
the most recent analysis hour.
URL-parameter loads (`/skewt?q=…`) were blocking the initial mount
on three serial steps: geocoder/grid resolve, ProfilesFile or
HrrrProfileLookup read, and the SkewtParams/SoundingParams/SkewtSvg
derivation. The address path in particular hits an external API,
which made the page take "forever" to load on first paint.
Restructure SkewtLive so the page chrome (header, search bar) renders
synchronously on mount, and the heavy work runs in a single
`start_async(:load_skewt, …)` task that calls SkewtLocationResolver,
walks the on-disk profile store with a DB fallback, and produces the
SVG. A new `loading?` assign drives a small spinner + "Resolving
location and loading HRRR profile…" message that shows while the task
is in flight; previous data stays on screen so navigation between
forecast hours doesn't blank out the diagram.
handle_async/3 covers three landings:
* `{:ok, {:ok, result}}` — apply assigns from the resolver
* `{:ok, {:error, reason}}` — surface as the existing error alert
(geocoder failure, unknown callsign, etc.)
* `{:exit, reason}` — log a warning and show a generic retry message
start_async/3 cancels any prior task with the same name on each call,
so a rapid-fire URL patch (e.g. clicking through forecast-hour
buttons before the first response returns) never lands stale data.
Tests: extended SkewtLiveTest from 3 to 4 cases — the URL-param
initial render now asserts the chrome + spinner appear pre-async,
and a separate case `render_async/2`s the view to confirm the
location label arrives once the task completes. 4/4 green.
When the on-disk ProfilesFile is empty SkewtLive falls back to the
hrrr_profiles Postgres table, but per-QSO HrrrFetchWorker rows
sometimes land with a partial profile (4–12 levels) when individual
byte-range fetches fail. The fallback was happily picking those rows,
which rendered a stubby Skew-T missing the upper troposphere.
HrrrProfileLookup.{list_valid_times_near, read_point_near}/3 now
filter on `coalesce(cardinality(profile), 0) >= min_profile_levels`,
defaulting to 13 (HRRR's standard pressure-level set: 1000/925/850/
700/500/400/300/250/200/150/100 mb plus the two boundary surfaces).
Pass `min_profile_levels: 0` to keep the partial rows for diagnostic
queries.
Confirmed against the dev mirror: the recent table has ~3.1 M rows
at 13 levels and ~250 k at 4–12 levels; the new default skips the
partial slice cleanly.
Tests: 8/8 HrrrProfileLookupTest cases (added two new ones for the
threshold). mix credo --strict clean.
Two changes that bring /skewt visually and analytically into parity
with the NOAA SPC sounding viewer
(https://www.spc.noaa.gov/exper/soundings/):
NOAA-style line set
-------------------
Updated the SkewtSvg style block to match the public SPC chart:
* Temperature trace ........ pure red (#ff0000) at 2.5 px stroke
* Dewpoint trace ........... pure green (#00aa00) at 2.5 px stroke
* Isotherms ................ dashed teal (#14b8a6)
* Dry adiabats ............. solid orange (#f59e0b)
* Moist (saturated) adiabats dashed sky-blue (#38bdf8)
* Mixing-ratio lines ....... dotted darker green (#16a34a), with
labels at 700 mb showing the g/kg
value, drawn only below 600 mb (matches
the SPC chart's lower-band number row)
* Parcel ascent ............ new dashed grey (#475569) line, drawn
whenever SkewtParams.derive returns a
non-empty parcel_trace
The mixing-ratio set is the SPC standard (0.4 / 0.7 / 1 / 2 / 3 / 5 /
8 / 12 / 16 / 20 g/kg) instead of the prior arbitrary set.
SkewtParams: SPC parcel-theory + indices module
-----------------------------------------------
New `Microwaveprop.Weather.SkewtParams` derives the parameter set that
ships in the SPC `*.txt` companion file:
* LCL pressure / temperature / height (Bolton 1980 eq 22)
* LFC pressure / height
* EL pressure / height
* SBCAPE, SBCIN (J/kg, virtual-temperature integration with
surface parcel)
* 3 km CAPE
* Lifted Index (parcel ↔ environment T at 500 mb)
* Freezing level (T = 0 °C height) and Wet-Bulb Zero
* DCAPE (downdraft CAPE — picks the min-θₑ source level in
400–700 mb, descends moist-adiabatically to surface)
* Layer lapse rates: sfc–3 km, 700–500 mb, 850–500 mb
* `parcel_trace` — pressure/temperature trajectory used by
SkewtSvg to draw the dashed parcel-ascent overlay
Wind-derived indices (SRH, BWD, Bunkers motion, SCP, STP, SHIP) are
deliberately *not* produced and the LiveView surfaces a one-line note
explaining why: HRRR persists wind only at 10 m AGL, so per-pressure-
level shear can't be computed from this data source.
LiveView panel restructured into grouped sections (Surface, Convective
parcel, Levels, Lapse rates, Moisture/stability, Refractivity) so the
layout matches the SPC viewer's order. The Levels rows show pressure
*and* height ("872 mb · 1,140 m") for quick cross-reference between
the diagram axis and the readout.
Tests: 8/8 new SkewtParamsTest cases (LCL Bolton check, saturated-air
edge case, full field-set presence, summer profile produces SBCAPE > 0
and LI < 0, capped profile produces SBCAPE = 0 and LI > 0, freezing
level interpolated correctly, sfc–3 km lapse rate, empty profile no
crash). 25/25 across all skewt-related test files. mix test green
(2,902 / 2,902 + 221 properties), mix credo --strict clean, mix
assets.build clean.
Two follow-ups to the earlier /skewt work:
1. Interactive crosshair (matches the SPC-viewer feel from the
reference screenshot). Mousing over the diagram now drops a
horizontal pressure cursor with a top-left readout box showing the
pressure at the cursor's altitude (mb), the height in m and ft,
and the linearly interpolated temperature and dewpoint at that
level. Two coloured dots track the T and Td traces along the
cursor so the user can read the spread visually.
Mechanics: SkewtSvg.geometry/0 exposes the plot geometry (left,
right, top, bottom, p_bottom, p_top, t_min, t_max, skew) as JSON;
SkewtSvg emits an initially-hidden <g class="skewt-cursor"> layer.
A new Skewt hook in assets/js/app.ts inverts pressure_y to recover
pressure from the cursor's viewBox-Y, walks the (descending-pres-
sorted) profile to interp T/Td/height, and updates the elements.
The hook also handles mouseleave to hide the cursor and uses the
SVG's screen-CTM so the math stays correct under any container
aspect-ratio resize.
2. DB fallback for `available_valid_times`/`load_profile`. When the
on-disk `ProfilesFile` has nothing for the location-and-window
(true on dev, transient on prod between chain runs), SkewtLive
now falls back to `HrrrProfileLookup.{list_valid_times_near,
read_point_near}/3` against the `hrrr_profiles` Postgres table.
The lookup uses the same ±0.07° spatial tolerance and the
`(lat, lon, valid_time)` unique index that `Weather.find_nearest_
hrrr/3` already relies on, so the queries are index-only.
Returned shape matches `ProfilesFile.read_point/3` so SkewtLive
reads from either source transparently. NaiveDateTime → UTC
normalisation is centralised in `ensure_utc/1` so the LiveView
sees `%DateTime{time_zone: "Etc/UTC"}` regardless of which side
produced the value.
Tests: 6/6 new HrrrProfileLookupTest cases (list/limit/tolerance,
read nearest cell, nil for far cells, picks closest among matches),
3/3 SkewtLiveTest still green, 2,894 total Elixir tests + 221
properties green via mix test (one pre-existing flaky test in
admin/contact_edit_live re-runs clean). mix credo --strict clean.
mix assets.build clean.
Both retired in light of the 2026-04-25 revision report
(`docs/algo-reports/2026-04-25-algo-revisions.md`):
* HPBL boundary-layer multiplier in `Scorer.score_refractivity/{3,4,5}`
is gone. On the n=47,418 10 GHz HRRR-matched corpus rho_hpbl is
+0.004; binned distance is flat to within ±5 % across 200–2,000 m.
The previously reported 2.3× ratio between shallow and deep HPBL
bins was a small-corpus artefact that disappeared once the matched
corpus passed ~5,000 contacts.
* Native-profile 1.15× duct boost is gone. At 10 GHz on n=52,341
matched contacts, cells where `best_duct_band_ghz` ≥ band ran
*shorter* than no-duct cells (198 km vs 211 km, n=173 vs 44,658).
The Bulk Richardson gate that existed only to suppress that boost
in turbulent conditions is also retired; arity preserved on every
`score_refractivity` overload so callers compile unchanged.
Same retirements applied in the Rust port (`rust/prop_grid_rs/src/scorer.rs`)
to keep the Elixir/Rust parity tests green.
algo.md updated end-to-end:
* Finding 4 (HPBL) rewritten to "no usable signal" with the
n=47,418 bin table.
* Finding 5 (gradient) tightened: load-bearing only at 24 GHz,
set band-specific gradient weight to 0 outside [10, 47] GHz on
the next derive_band_weights run.
* Finding 8 (time-of-day) augmented with the robust hour-bucketed
amplitude index (40 / 82 / 101 % at 10 / 24 / 47 GHz) and a
selection-bias caveat for VHF/UHF (where 129–148 % amplitude
reflects evening contest scheduling, not propagation).
* Finding 9 (sounding) refreshed against the n=27,058 corpus.
* Part 2c "Native-profile duct boost" rewritten as
"retired 2026-04-25" with the falsifying join.
* Part 2c "Commercial-link inverse sensor" promoted from deferred
with the 22-day, 38k-sample SNMP corpus, the +0.61 / −0.61 PWAT
and pressure correlations against the 37-hour HRRR overlap, and
the 04–05 / 10–12 local two-peak morning fade window.
* Part 2b "Pressure" annotated with the U-shape at 10 GHz and the
next-iteration target.
* Part 2d "What stayed, what left" + "Open items" updated to
reflect the four code/doc moves.
119 Elixir scorer tests green, 134 Rust scorer tests green, 2,888
total Elixir tests + 221 properties green via `mix precommit`.
Single search bar accepts an address, Maidenhead grid square, or
callsign; resolves it to lat/lon via Geocoder / Maidenhead /
CallsignLocation (cheapest classification first), snaps to the HRRR
grid via the existing ProfilesFile reader, and renders an SVG
Skew-T-Log-P with isobars, skewed isotherms, dry/moist adiabats, and
mixing-ratio lines. A button row picks between every available
forecast hour (now → f18); default is the most recent analysis.
Right pane lists derived stability and refractivity stats from
SoundingParams.derive (PWAT, BL depth, K-index, lifted index, min
dN/dh, ducting status + per-duct base/top/ΔM).
Renderer is server-side SVG so the page works without JS and serializes
into the LiveView payload as a single tag. Wind barbs are deliberately
omitted — HRRR's persisted profile carries wind only at 10 m AGL.
Each fix is covered by a regression test that fails on `main` and
passes on this commit.
Round 1 (initial review):
* propagation: thread `latitude` into the conditions map so
`score_season/4` actually picks up regional multipliers
* hrrr_client / fetcher.rs: `nearest_hrrr_hour` rounds DOWN, never at
a future cycle that NOAA hasn't published yet
* radio: spherical-vector great-circle midpoint replaces the
arithmetic mean — anti-meridian paths no longer fold to Greenwich
* weather: `reconcile_weather_statuses` scales the longitude band by
`1 / cos(lat)` so the bbox stays ~150 km wide at every latitude
* radio/maidenhead: clamp 90°/180° below the field-bucket overflow so
`from_latlon` never emits invalid characters like 'S'
* prop_grid_rs/pipeline: merge HRRR + NEXRAD-derived rain rates and
read `best_duct_freq_ghz` into `best_duct_band_ghz` so the Native
Duct Boost actually fires
* propagation/region (Elixir + Rust): inclusive upper bounds so points
exactly at lat_max get the regional multiplier
* weather/sounding_params (Elixir + Rust): drop the 10 m gradient
floor so HRRR's thin near-surface layers stop hiding sharp ducts
* weather/sounding_params: when the profile ends inside a duct,
finalize it with the highest sample as the top instead of throwing
it away (Rust port already correct)
Round 2 (post-fix sweep):
* radio + commercial: single canonical haversine in Radio (atan2
form); Commercial delegates instead of carrying a second copy that
could disagree at threshold distances
* prop_grid_rs/profiles_file: `snap_coords` matches Elixir's
step-aware snap (`round(coord/0.125) * 0.125`, then 3-dp round) so
Rust-keyed and Elixir-keyed profile maps land on the same cell
* weather/grib2/wgrib2: `parse_lon_val_segment` uses `Float.parse`
uniformly — wgrib2 dropping the trailing `.0` from a longitude no
longer crashes the whole chain step
`handle_event("switch_tab", ...)` ran `String.to_existing_atom/1` on
the raw `tab` value from the browser, so a stale, forged, or
mistyped client event with any unknown string crashed the LiveView
with `ArgumentError: not an already existing atom`.
Compares against an explicit `@valid_tabs` allowlist (`:single`,
`:csv`, `:adif`) — known values switch the active tab, anything
else is ignored.
`apply_edit_to_contact/2` is the path for both owner direct-edits and
admin reviewed-edits. The public contact-map + total-count + gzipped
controller payload caches are built from `private == false` rows, but
only the insert path was clearing them — every other update left
/api/contacts/map and /contacts/map serving the previous snapshot for
up to 10 minutes. A `private: false -> true` flip on a contact already
present in the cached payload was a temporary privacy leak; grid
corrections, callsign changes, and flagged_invalid flips silently
diverged from the live row.
Extracts the three `Cache.invalidate` calls into
`invalidate_contact_map_caches/0` and runs it from both
`apply_edit_to_contact/2` and the existing insert path so the public
view stays in sync.
The /contacts/:id edit form always submits the `private` checkbox, but
`current_value/2` had no `"private"` clause and fell through to the
catch-all `nil`. The Contact schema defaults `private: false`, so an
unchanged box compared `false != nil` and was always tagged as a
change — for non-owners that meant a spurious pending review queued
on every save, and for owners/admins it triggered a no-op direct
update.
Adds the missing clause so the diff sees boolean-vs-boolean and
correctly returns `:no_changes` when the box is untouched.
The /contacts/:id edit form pre-fills qso_timestamp via
`Calendar.strftime(ts, "%Y-%m-%d %H:%M")` and submits whatever the
user typed back unchanged. Two failure modes resulted:
1. `diff_against_contact/2` compared that string against the stored
`%DateTime{}`, never matched, and treated every untouched submit
as a modification.
2. `build_contact_changes/2` then ran `DateTime.from_iso8601/1` on
the space-separated, no-seconds, no-Z form and crashed with
`MatchError` on `{:error, :invalid_format}` — direct owner/admin
submits raised instead of saving.
Adds `normalize_timestamp_field/2` to `normalize_proposed/1` that
parses both the form's `"YYYY-MM-DD HH:MM[:SS]"` and the strict
`"YYYY-MM-DDTHH:MM:SSZ"` shapes into a UTC `%DateTime{}` (with
`NaiveDateTime.from_iso8601` doing the heavy lifting after a small
seconds-padding pass). Empty strings drop the field; unparseable
input drops it too so a typo becomes "no changes" rather than a
500.
Bandit's dual-stack listener delivers IPv4 connections to the app as
IPv4-mapped IPv6 tuples (`::ffff:a.b.c.d`). The trust check compared
that 128-bit form against our IPv4 trusted_proxies CIDRs and never
matched, so cf-connecting-ip was ignored on every cloudflared-relayed
request — every visitor logged as the cloudflared sidecar pod IP
(rendered as `0:0:0:0:0:65535:2804:101` etc.).
Collapses the mapped tuple to plain IPv4 before the trust check and
records it that way on the conn, so logs and session storage see the
real client IP that Cloudflare set in cf-connecting-ip.
Adds a `layer` query parameter to `/weather`. Loading
`/weather?layer=temp_700mb` boots straight into that overlay; clicking
a different layer pill push_patches the URL so the active selection is
shareable and survives a refresh. Unknown layer ids fall back to the
default (temperature) instead of crashing.
PropagationGridWorker hard-coded `now-2h` for run_time selection on
the conservative theory that NOAA always finishes publishing within
two hours. In practice f18 is on the mirror by HH:55–HH:00 of the
next hour, so the cron at HH:05 was always picking a cycle that was
already an hour stale.
`HrrrClient.cycle_available?/1` HEADs the wrfprsf18 idx (the slowest
file in the cycle) — a 200 means every earlier forecast hour is also
on disk. `pick_run_time/1` probes `now-1h` first; if the probe
returns true we use that cycle, otherwise we fall back to the
existing `now-2h` slot. Test hook via :hrrr_cycle_available_fn env
keeps the behaviour fully exercisable without hitting NOAA.
End-to-end: weather/score data lag drops from ~2 h to ~1 h on every
hour where NOAA delivers on time. The fallback path keeps the chain
running on slow-publish hours.
850 mb T alone shows that warm air is present aloft but doesn't reveal
whether it's the textbook cap structure — a warm 700 mb above an EML
plume. The three new layers expose the canonical capping diagnostics
visually:
* T @ 700 mb — ≥10 °C is the southern Plains "moderate cap" threshold
* Td @ 700 mb — wide T-Td depression at 700 mb signals the EML plume
* Lapse 850→700 — steep mid-layer lapse rate (≥7 °C/km) over a moist
boundary layer is the cap mechanism itself
All three derive purely from the existing pressure-level profile (Rust
already fetches up through 700 mb), so no Rust pipeline changes needed.
ScoreCache held 437 entries × ~1.94 MiB each (~850 MiB per pod) of
{band_mhz, valid_time} grids — data already on NFS as compact .prop
files. NotifyListener and ScoreCacheReconciler both eagerly materialised
every band into ETS on each Rust completion / 60s sweep, so 5 hot
replicas wasted ~4.2 GiB of redundant cache and OOMed at 6 GiB.
Bound the cache to 32 entries with eviction by oldest valid_time, drop
the eager warm loops, and let LiveView callers lazy-fill via the
existing ScoresFile read path. ScoreCacheReconciler had no remaining
purpose and is deleted; runbook + prom_ex counters updated to match.
Steady-state cache footprint ~60 MiB per pod instead of ~850 MiB.
The Rust f01..f18 pipeline writes ProfilesFile cells, and the Rust
hrrr_points worker writes hrrr_profiles rows, with profile entries
keyed "pres_mb" / "hght_m" / "tmpc" / "dwpc" (string keys pre-
atomization; atom keys post-ProfilesFile.read). Elixir's
SoundingParams.derive and WeatherLayers.sort_profile filtered on
"pres" / "hght" — so every derived field returned nil for any
Rust-provided profile.
Visible symptoms on /weather: N-gradient, Refractivity, T @ 850mb,
Td @ 850mb, Lapse Rate, Inversion, Inv. Base all rendered no overlay.
For per-contact analysis, min_refractivity_gradient from the Rust
HRRR point worker's rows silently dropped.
- SoundingParams.normalize_profile_entry/1: single-source normalizer
accepting legacy, Rust-string, and Rust-atom shapes; returns the
canonical "pres"/"hght"/"tmpc"/"dwpc"/"drct"/"sknt" shape.
- SoundingParams.derive/1 and WeatherLayers.sort_profile/1 both run
every entry through it before the rest of the existing logic.
- Weather.build_grid_cache_row/4 now falls back to native_min_gradient
when SoundingParams can't derive one (surface-only profiles).
Also:
- Default /weather overlay changed to Temperature (LiveView assign +
JS fallback in the hook's dataset default) per user request.
Extends the weather-status reconciler with symmetric sweeps for HRRR
and IEMRE. Same failure mode: the worker writes data to the shared
table but has no back-pointer to the contact that triggered the
fetch, so contact-level status never flips unless a user views the
page.
- Weather.reconcile_iemre_statuses/0: iterates :queued contacts;
flips :complete when every path point has an iemre_observations
row at the rounded 0.125° grid cell for the qso_timestamp's date.
- Weather.reconcile_hrrr_statuses/0: same shape; flips when
hrrr_data_fully_present?/1 holds.
- Both run alongside the existing weather sweep at the tail of
ContactWeatherEnqueueWorker.perform/1.
Kept in Elixir (not SQL) because contact_path_points/1 emits 1-3
points per contact and grid-rounding each in pure SQL is awkward.
The stuck-at-steady-state count is always tiny (<20), so the
iteration is cheap.
2,019 contacts sat permanently in weather_status=:queued even after
their ASOS data had been ingested. The only code path that flipped
:queued → :complete was MicrowavepropWeb.ContactLive.Show on page
view — contacts that nobody visited stayed :queued forever.
Adds Weather.reconcile_weather_statuses/0, a single SQL UPDATE that
flips every :queued contact whose ±2h / 150km window now contains
at least one surface observation. Called at the tail of the
existing ContactWeatherEnqueueWorker cron so the correction runs
regardless of whether anyone opens the UI.
Visible effect: the status page's "Weather done" count (previously
capped at 79,975 while data kept landing) will converge on the real
total after the next cron tick.
2838 tests + credo green.
Replaces per-QSO-endpoint asos_batch granularity with per-station-day
granularity. Each contact in the same UTC day near the same station
now produces identical unique-args and collapses to ONE Oban job, so
the backlog shrinks as cross-contact duplicates dedup.
Each fetch also covers a full 24h window (vs the previous 4h) so one
IEM request returns ~24 hourly observations instead of ~1-2. The
effective bytes-per-request is 10x higher, amortizing the
IemRateLimiter gap + 429 retry tail across far more data.
Changes:
- Weather.station_day_covered?/2 + station_day_pairs_covered/1 — cheap
UTC-day coverage checks for the enqueuer + worker skip paths.
- WeatherFetchWorker gains an "asos_day" clause that fetches the full
UTC day for one station and upserts. Skips if the day is already
covered in the DB.
- ContactWeatherEnqueueWorker.build_asos_jobs/3 now emits one asos_day
job per (station_id, UTC date) pair. ±2h windows crossing midnight
enumerate both dates.
- Microwaveprop.Weather.RebatchAsos.to_day_jobs/1 migrates any
already-queued asos/asos_batch jobs into the new shape. Idempotent;
supports dry_run.
- asos_batch worker clause retained for jobs already in flight at
deploy time.
2835 tests + credo green.
Mix.Task.run isn't available in a compiled release, so the in-prod
`bin/microwaveprop eval 'Mix.Tasks.Weather.RebatchAsos.run(...)'`
dispatch crashes. Moves the real logic into a plain module
(`Microwaveprop.Weather.RebatchAsos`) that both the Mix task and a
release eval can call. Uses IO.puts over Mix.shell for the same
reason.
- IemRateLimiter gains AIMD-style adaptive spacing. signal_429/0
widens the current gap (*= 1.5, capped at max_interval_ms default
10s); signal_success/0 narrows it back toward the configured base
(*= 0.92, floored at interval_ms). Self-tunes to IEM's moving
ceiling without needing the manual "safe for 4 pods" constant.
- IemClient now routes every response through a central handle_response
helper that fires the widen/narrow feedback signals, eliminating the
four near-identical case blocks.
- Mix.Tasks.Weather.RebatchAsos collapses any already-queued single-
station "asos" jobs into the batched "asos_batch" shape the
enqueuer now emits, so the pending backfill queue converts to the
new per-request-efficient path instead of draining at the old rate.
Idempotent; supports --dry-run.
