The producer-only path left older hours stuck at 0% HRRR coverage
forever once their fetch tasks drained: the rolling-window cron only
re-passes the prior hour, so manual lookback runs (or any
out-of-window hour) wrote NULL samples + enqueued tasks, then never
re-ran to UPSERT the now-landed HRRR data.
Fix: split the responsibility cleanly.
* CalibrationSampler.build_for_hour/1 now returns
%{upserted: int, missing_hrrr_cells: int} so callers know whether
the producer enqueued anything (i.e. whether a follow-up makes
sense). Spec-tightened with a new @type result.
* PskrCalibrationWorker, after each hour's sampler pass, schedules a
follow-up of itself for that exact hour 10 min later when missing
> 0. The follow-up carries args %{"hour_utc" => ..., "_follow_up"
=> true}; the sentinel prevents follow-ups from chaining further
follow-ups (rolling-window cron is the safety net).
Tests:
* Updated 4 existing sampler tests to the new map return shape.
* Moved the follow-up assertions from the sampler suite into the
worker suite where they belong (sampler is now scheduling-free).
* Added 3 worker tests: schedules-when-missing, no-schedule-when-
covered, follow-up-doesn't-chain.
3313 tests + 228 properties, 0 failures.
Adds the test that verifies the full producer→drain→re-pass loop:
sample written with NULL HRRR fields + fetch task enqueued, then once
an HRRR profile lands, the next sampler pass UPSERTs the same
calibration_samples row (id preserved) with non-NULL weather data.
Also tightens dialyzer surface:
* PartitionManager defines a `result()` typedoc and uses it on both
public functions instead of inlined tuple types.
* PartitionMaintenanceWorker.perform/1 + the lookahead/1 helper get
explicit specs.
* CalibrationSampler.enqueue_missing_hrrr/3 gets a spec covering its
group_by-shape input map and HRRR profile list.
`mix precommit` clean (3310 tests, 0 failures). Local `mix dialyzer`
hits an OTP 28.4 vs 28.5 toolchain mismatch unrelated to this change.
Partition list for hrrr_profiles + hrdps_profiles was hand-edited in
priv/repo/structure.sql; if no human extended it, writes for the next
quarter would silently fail at the worker level (Rust hrrr-point-worker
marks tasks failed; the calibration pipeline silently joins NULLs).
Adds:
* Microwaveprop.PartitionManager — runtime DDL helper. Quarter math via
a single integer index (year*4 + quarter) for rollover safety.
Coverage check via pg_inherits before CREATE so a quarterly target
inside an existing wider partition (some 2027 ones are half-year)
is treated as :exists rather than colliding.
* Microwaveprop.Workers.PartitionMaintenanceWorker — daily cron at
03:15 UTC, 4-quarter lookahead. Idempotent; cheap when nothing's
missing. lookback_quarters arg lets ops widen for catch-up.
Tests cover the create + idempotent re-run + name format + year
rollover paths via a synthetic parent created inside the sandbox
transaction (no DDL leaks into the shared test DB).
Old design fired hourly at HH:25 and built one whole hour of cells
in a single batch. During PSKR peaks (50k+ spots/hour) that batch
held the DB pool long enough to look like a backlog, and a pod
restart between fires lost a full hour because the next cron only
caught the most-recent-prev hour.
- Default window is now current hour + 1 prior. Every 5-min fire
spreads work across the in-flight hour and always covers the
boundary without waiting for the next cron tick.
- lookback_hours arg widens the window for catch-up
(e.g. {"lookback_hours": 24} sweeps the last day after an
outage).
- Unique period 3600 → 240 so consecutive 5-min cron fires actually
slot in.
UPSERT is already idempotent so the ~12 redundant passes per hour
cost only the read+merge. Latency from spot ingestion to sample
creation drops from up-to-60min to ≤5min.
`Pskr.Recalibrator.run/0` reads `pskr_calibration_samples`, bins
each sample per (band × feature), and writes spot-density stats to
`pskr_feature_bins` so an operator can read whether a feature
actually discriminates propagation at the threshold granularity
the scorer uses.
Bins, not regression: `BandConfig` already encodes scoring as
discrete thresholds, so the bin output matches that shape and an
operator can copy adjusted thresholds directly without translating
from regression coefficients.
Self-healing: corpus too thin ⇒ run row written with status
`skipped_insufficient_data` and the analysis is a no-op until next
fire. `min_total_samples = 1000` (≈ 4-5 days of CONUS PSKR
activity); per-band threshold is 100. Both surface in the run row's
`notes`.
Auto-applies nothing. Weight changes still go through human review
of `BandConfig.@band_configs` and a code commit. The recalibrator
is a read-only analyst that stays out of the production scoring
path.
Features binned (matching the scorer's discriminating fields):
* pwat_mm — humidity U-shape candidate
* hpbl_m — boundary layer (mechanism vs scoring re-eval)
* min_refractivity_gradient — refractivity threshold validation
* surface_pressure_mb — pressure-front proxy
* kp_index — aurora boost magnitude tuning
Schema: two tables.
* `pskr_recalibration_runs` — one row per fire with corpus
stats, status, notes
* `pskr_feature_bins` — one row per (run, band, feature, bin)
with sample_count, spot_count_total/avg/p50/p90
Cron: `0 4 * * 0` (Sundays 04:00 UTC, off-peak, post-climatology).
Manual reruns enqueue with no args.
Tests cover the empty-corpus skip path, sub-threshold totals,
per-band threshold gating, the actual bin emission, nil-feature
handling, spot-count averaging, and the always-records-a-run
audit invariant. 8 new tests, 3282 total passing.
Backfill pipeline untouched.
PSK Reporter is now an always-on data feed, so the calibration
corpus that recalibration will eventually train against can grow
hourly from when the firehose started. One row per (hour, band,
0.125° midpoint cell) joins three sources:
* `pskr_spots_hourly` — observed spot density (truth signal)
* `hrrr_profiles` nearest match at the cell midpoint at hour
boundary (atmospheric features: T, Td, PWAT, P, dN/dh, HPBL,
ducting flag)
* `geomagnetic_observations` latest Kp at the hour (space weather)
Predicted scores are intentionally NOT stored — they're a function
of the algorithm version under evaluation. Storing only features
keeps the corpus stable across every weight refit; the recalibrator
computes predictions on demand.
Components:
* Migration `20260504210756_create_pskr_calibration_samples` —
new table + unique index on (hour, band, midpoint_lat, lon),
plus a midpoint spatial index on `pskr_spots_hourly` to keep
the join cheap.
* `Pskr.CalibrationSample` — schema mirror of the table with
the same `(hour, band, midpoint_lat, lon)` unique constraint.
* `Pskr.CalibrationSampler.build_for_hour/1` — pulls all spots
for the hour, snaps midpoints to the propagation grid (0.125°),
builds an in-memory HRRR index over a ±0.07°/±60 min window,
and bulk-upserts samples. Idempotent — re-runs upsert.
* `Workers.PskrCalibrationWorker` — Oban cron entry on the
`:backfill_enqueue` queue. Default args target the previous
full hour; explicit `hour_utc` arg reruns any hour.
* Cron `25 * * * *` — fires past HRRR analysis publish window
(~HH:50→HH:05) and PSKR aggregator's 60s flush.
Forward-only: PSKR has no historical archive, so the corpus only
grows from when the feed started. Recalibration weight refits
should wait for ~30 days / ~10k samples to cover diurnal and
synoptic variability.
Tests cover cell-snapping, HRRR feature joining, Kp stamping,
median-distance aggregation, mode dedup, idempotent reruns, and
the worker's default-hour and explicit-hour args (12 new tests,
all passing).
Backfill pipeline untouched — none of these changes feed into
contact enrichment.
Both RTMA and METAR5 schemas + clients + workers were defined but
never had a consumer. `find_nearest_rtma/3` and `recent_surface_obs/3`
existed in `Microwaveprop.Weather` with zero callers cluster-wide;
RtmaFetchWorker had test coverage but was never enqueued anywhere;
no IEM 5-min ASOS fetcher was ever written. The tables sat empty in
prod and the recalibrate audit was permanently flagging them BROKEN
even though the empty state was the steady state.
Drop the lot — schemas, clients, workers, queue config, Req.Test
stubs, audit checks, and the per-table unique tests in the
observation-changesets suite. New migration drops the now-unreferenced
`rtma_observations` and `metar_5min_observations` tables (both 0
rows in prod). Trim the `:rtma` slot out of `backfill_only_queues`
in runtime.exs so Oban Pro's Smart engine stops trying to manage a
queue with no producer.
Audit thresholds reset on the surviving NARR check: drop the
"WARN < 5000 absolute rows" rule that didn't account for
NarrFetchWorker's 0.13° spatial dedup, and point remediation at
the existing BackfillEnqueueWorker cron instead of the dev-only
`mix narr.backfill` task.
scripts/recalibrate_algo.py: ROW_COUNT_SOURCES + DATA_GAP_SQL +
DATA_GAP_RULES all stop referencing the dropped tables.
The :terrain queue at 3 slots/pod was sized for the lightweight per-QSO
TerrainProfileWorker, but RoverPathProfileWorker now runs the full
PathCompute pipeline (terrain + 9 HRRR profiles + sounding + ionosphere
+ scoring + loss + forecast) — same heap profile as :propagation, which
sits at 1 slot precisely to avoid OOM.
A backfill_paths flood today queued ~200 rover-path jobs. With 4 hot
pods × 3 slots, the cluster stacked 15 concurrent path-computes and
two pods OOM-killed in a loop, taking the libcluster ring with them
(visible as the "unable to connect" warnings on the surviving pods).
New :rover_path queue at 1 slot/pod caps cluster-wide concurrency at
(hot_replicas + 1 backfill), drains the existing 200-job backlog
inside ~30 min, and keeps :terrain free for the cheap workers it was
sized for.
Three connected changes:
1) Extract PathLive.compute_path/4 + every helper it owned (resolve,
profile grid lookup, sounding/ionosphere readouts, scoring, loss /
power budgets) into Microwaveprop.Propagation.PathCompute. PathLive
now delegates; ~410 lines of dead helpers deleted from PathLive.
2) RoverPathProfileWorker calls PathCompute.compute/4 with the
mission's heights and PathLive's default station params (10 W TX,
30 dBi gains). Stores the full atom-keyed compute output as a
Base64-encoded :erlang.term_to_binary/1 blob alongside the flat
summary fields the rover-planning show table reads. The blob
roundtrips structs and DateTime exactly (Jason.encode would lose
them).
3) PathLive accepts ?rover_path_id=UUID. When set, loads the cached
Path, decodes the term (binary_to_term :safe), assigns it as
@result, and renders normally — no compute_path call. The
rover-planning show table now links rows directly to
/path?rover_path_id=UUID, so a click opens the full Path
Calculator UI from cached data without re-running terrain / HRRR /
sounding lookups.
Bonus prod fixes folded in:
- PathShow's elevation chart attribute (data-* → data-profile JSON)
was crashing the JS hook with 'unexpected character at line 1'.
- Station.changeset now wipes previously-resolved callsign/grid/
lat/lon when the user types into :input — typing 'AA5' early
resolved to a wrong location and locked it; subsequent keystrokes
never re-resolved.
- phx-debounce=600 on the station input so QRZ doesn't get hit on
every keystroke.
Worker now stores the full per-point analysis (beam height,
Fresnel-zone radius, clearance) on Path.result.path_points, and
PathShow renders a real cached page: terrain elevation chart fed by
the same ElevationProfile JS hook /path uses (feet on Y, miles on X,
LOS + Fresnel overlay), distance / bearing / clearance / antenna
heights all in feet, baseline link-budget breakdown, and the cached
midpoint propagation score with computed_at timestamp.
A Recompute live button hands off to /path for the time-varying bits
(current HRRR conditions, scoring breakdown, sounding, ionosphere)
that aren't worth caching.
Two fixes:
1) Form save / rover-site add/remove no longer runs the path-matrix
reconcile inline. update_mission and the show LiveView now
enqueue a single RoverMissionReconcileWorker job and return —
for missions with many rover sites x bands the inline path was
firing hundreds of Multi inserts + Oban.inserts on the request.
2) RoverPathProfileWorker.load_path/1 now strictly matches a
4-tuple (mission_id, rover_location_id, station_id, band_mhz)
with band_mhz as an integer, plus updates the Oban unique key
set to include band_mhz so multi-band missions enqueue per-band
jobs (not just one). Legacy/malformed args are logged and
dropped instead of crashing the queue with MultipleResultsError.
Mission now carries bands_mhz ({:array, :integer}) — operator picks
one or more bands as multi-checkboxes. enqueue_paths_for builds the
cross product (rover x station x band) and persists each tuple as its
own Path row keyed by (mission_id, rover_location_id, station_id,
band_mhz). The path-profile worker reads band_mhz from the path
itself (legacy single-band jobs without band_mhz in args still resolve
to their unique row).
replace_mission_paths/1 is now a thin alias for reconcile_mission_paths/1
which diffs desired vs actual: stale tuples (old band that the user
unchecked, station they removed, rover-site they deleted) get dropped,
new tuples become :pending and enqueue, surviving :complete rows are
left in place — no more wholesale destruction of already-computed
paths on every edit.
The show table gains a Band column, and band_label() in the mission
summary becomes bands_label() (joins the list with commas).
The path-profile worker now also computes the baseline link-loss
budget — free-space path loss, oxygen absorption, baseline H2O loss
(at 7.5 g/m^3 default humidity), plus the already-cached terrain
diffraction — and stores all four numbers in Path.result. The show
page renders the per-row total in a new Loss column. /path still
recomputes against live HRRR weather; this is the offline-readable
cached snapshot.
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 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.
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.
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.
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.
GefsFetch silently dropped crashed score-computation tasks via
`{:exit, _reason} -> []`, hiding partial-grid outages from k8s logs.
HRRR range downloads mapped exits to `{:error, reason}` without logging
the URL, so the failing range was lost by the time the caller surfaced
the error.
All three sites now Logger.error with enough context (fh, valid_time,
url) to debug from production logs.
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.
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.
IEM's ASOS CSV endpoint accepts multiple station= params in a single
request. Prior code enqueued one WeatherFetchWorker job per nearby
station per QSO endpoint — N jobs × 1 station each — which paid the
IemRateLimiter's 1500ms gap and the IEM 429-retry tail N times per
contact.
Changes:
- IemClient.asos_url/3 accepts a list of station codes.
- IemClient.fetch_asos_batch/3 fetches N stations in one call and
returns rows grouped by station_code (with absent codes filled as
empty lists so callers can stub them).
- parse_asos_csv/1 now exposes the station_code column it was
previously discarding.
- WeatherFetchWorker gains an "asos_batch" fetch_type clause that
unpacks rows per (station_id, station_code), upserting or stubbing
each. The single-station "asos" clause stays for already-queued
retryable jobs.
- ContactWeatherEnqueueWorker.build_asos_jobs/3 now emits one batch
job per (lat, lon, 4h window) covering every uncovered nearby
station (sorted for deterministic unique-args).
Expected effect on backfill: ~10-20x fewer IEM requests per contact
enrichment cycle, matching drop in 429 retry traffic.
Root cause of 14 stuck hrrr-queued contacts: hrrr_point_rs's CONUS-only
grid silently writes zero profiles for out-of-bounds points (UK,
Winnipeg, Alberta, >50° lat), but the fetch task still completes
successfully. ContactWeatherEnqueueWorker's hrrr_placeholder_jobs
always emitted a queued placeholder for any contact with a pos1,
which meant mark_hrrr_status! re-flagged :queued every backfill tick
forever.
Introduce Propagation.Grid.contains?/1 as the canonical in-CONUS
check (inclusive on all four edges, nil-safe). Use it in two places
of ContactWeatherEnqueueWorker:
- hrrr_placeholder_jobs/1 now returns [] for OCONUS contacts, same
as pre-2014 / already-complete ones.
- mark_hrrr_status!/3 empty-list clause now branches on Grid.contains?
first (→ :unavailable) before falling through to the existing
NARR-coverage / :complete logic.
Next backfill tick will flip the 14 stuck OCONUS contacts in prod to
:unavailable automatically. The remaining 13 "CONUS" stuck ones are
right at the 50° edge (lat=50.1875 rounds outside the box) — same
reconciliation path.
Coverage additions:
- Grid.contains?/1 — corner-inclusive, OCONUS positive/negative
fixtures based on the actual stuck-contact pos1 values, nil/missing-
key/nil-value handling.
- enqueue_for_contact regression tests: pos1 in the UK and pos1 just
north of the lat cap both land at :unavailable, not :queued.
Suite: 2,416 tests + 159 properties (was 2,409 + 159); credo strict
clean.
Changes under lib/ (source):
- iemre_fetch_worker: replace `if transient_failure?/1` boolean predicate
+ `if/else` with a classifier that pattern-matches the error reason
directly, returning `:transient | :permanent`, and dispatch via
`case`. Three-clause head is clearer than the boolean predicate.
- scores_file.extract_points and nexrad_client.extract_box: force `//1`
step on the row/col comprehensions so an image box whose centre
lands outside the raster collapses to an empty iteration instead
of firing Elixir 1.19's ambiguous-range warning. Adds a regression
test for the right-edge box.
Test coverage added:
- Feature wrappers in Backtest.Features (theta_e_jump, shear_at_top,
duct_thickness, best_duct_freq, duct_usable_for_band,
distance_to_front / parallel_to_front stubs, all_features/0).
- NotifyListener handle_info tolerance for malformed payloads +
unknown messages, plus the PubSub broadcast side effect.
- Viewshed.effective_reach_km across every verdict / diffraction
tier / ducting-score tier combination.
- SnmpClient parse_af60_output unit conversions + unknown-column
handling; parse_snmpget_output OID normalisation and junk-line
tolerance.
- HrrrNativeClient native_level_count, native_variables,
native_messages shape, duct_messages / duct_byte_ranges.
- Changeset coverage for GeomagneticObservation, SolarFluxObservation,
SolarXrayObservation, Ionosphere.Observation, HrrrClimatology, and
Metar5minObservation — lifted each from ~50% / 0% to 100%.
- Property tests: GefsClient.dewpoint_from_rh invariants (Td ≤ T,
monotonic in RH, finite across the operating envelope) + idempotent
nearest_run. NexradClient.pixel_to_dbz monotonicity + bounded
output; latlon_to_pixel round-trip for every grid cell.
Also cleared several unrelated compiler/linter warnings:
- Three private test helpers (create_contact, insert_contact,
current_hour) had `\\ %{}` / `\\ 0` defaults that no caller used.
- profiles_file_test bound `dir` in a pattern match without using it.
Suite: 2,359 tests + 146 properties pass (was 2,300 / 139); coverage
70.38% → 70.89%; credo strict clean.
Rust workers (prop-grid-rs) that die mid-claim (SIGKILL, OOM, node
drain) leave grid_tasks rows stuck in status='running' forever,
because claim_next uses FOR UPDATE SKIP LOCKED and nothing resets the
orphan. The /status page then shows a permanent spinner with stale
f00/f10/f18 badges — currently 21 rows claimed as far back as
2026-04-20.
GridTaskEnqueuer.reclaim_stale_running/1 flips rows whose claimed_at
is older than 15 minutes back to 'queued'. Rows that have already
burned through 5 claim/reclaim cycles become 'failed' with a
reclaim-orphan error so the next hourly seed can replace them.
Wired into PropagationGridWorker.seed_chain/0 so it runs every :05
cron tick before new rows are seeded.
Also rename the status panel "Retrying" column to "Failed" — it was
always showing terminal `failed` rows, never retrying ones.
IemreFetchWorker now writes an empty stub observation when IEM returns
a permanent-failure status (404, 422), mirroring the existing {:ok, []}
path. The backfill cron's next tick sees the stub via
has_iemre_observation?/3, generates no job, and mark_status!/3 flips
the contact's iemre_status from :queued to :complete — draining the
51 contacts that have been stuck behind cancelled out-of-grid IEMRE
jobs.
Raise hot pod CPU limit 2 → 3 so BEAM gets 3 schedulers online.
Observed run queues of [2, 10, 0, 0, 0, 0] on the 2-scheduler
configuration during the :05 propagation chain, starving /live and
/health probe handlers and tripping intermittent liveness timeouts.
When the Rust hrrr-point-worker marks a task as `failed` (upstream
`idx HTTP 404` or wgrib2 decode error on old archive formats), the
corresponding contacts sit at `hrrr_status = :queued` until the
generic 3-day stale-queued reconcile flips them. Speed that up: on
every BackfillEnqueue tick, join contacts to `hrrr_fetch_tasks` by
rounded HRRR hour and flip any `:queued` contact whose cycle is
permanently `failed` to `:unavailable` immediately.
Motivation: a handful of 2018-08-04/05 cycles (t20z/t21z/t15z/t17z)
are genuinely missing `wrfsfcf`/`wrfprsf` files on the NOAA S3
archive — other hours on the same dates are fine, so this is an
upstream data gap rather than a structural pre-2019 issue. Users
see an accurate "Partial" marker on those contacts instead of a
three-day `:queued` stall.
Tested: 4 new cases covering rounding, failed-vs-done, and the
`hrrr not in types` skip branch; full suite 2283/0.
Three bugs were letting mechanism/terrain/radar contacts ping-pong
between :complete and :queued on every backfill cron:
1. enqueue_for_contact/2 now filters out types that are already
:complete on the contact before building jobs. Previously
mark_status!/3 demoted every non-empty jobs_by_type entry back to
:queued, overwriting the :complete that workers had just set.
2. reconcile_stale_queued/1 now also flips mechanism_status and
radar_status back to :complete when the companion data
(propagation_mechanism / contact_common_volume_radar) already
exists. Drains the existing ~14k row backlog on the first post-
deploy tick.
3. IemClient.parse_iemre_json/1 accepts "" and nil so a 200-with-
empty-body IEMRE response doesn't FunctionClauseError the worker
through four retry attempts.
StatusLive had a hand-rolled thousands-separator format_number/1 and a
binary-prefix format_bytes/1 — duplication that was already part of the
review punch-list. Move both to Microwaveprop.Format (which previously
held only distance_km) and delete the local defps. Fourteen call sites
switched to Format.number / Format.bytes.
Also extend the IEM error classifier to snooze on Req.TransportError
{:closed, :timeout, :econnrefused, :nxdomain}. Same rationale as the
429 snooze in batch 1: upstream TCP resets mid-fetch aren't a job
failure, they're transient — returning {:error, _} blows them up into
Oban.PerformError logspam with full stacktraces.
Batched from a system-wide review pass.
**Rate-limit + transient-error log hygiene**
- WeatherFetchWorker: classify IEM HTTP 429 as {:snooze, 300} instead
of {:error}. Stops Oban.PerformError stack-trace spam on every
routine rate-limit during backfill, keeps the retry semantics.
- IonosphereFetchWorker: compress GIRO TLS :unknown_ca error from a
~400-char inspect blob to 'TLS unknown_ca (CA bundle missing)'.
- FreshnessMonitor: log only when an enqueue actually lands (the
Oban unique conflict case was silently dropping jobs but still
producing 'enqueuing grid worker' info lines every 5 minutes).
**Perf**
- Rust grid_level_keys(): pre-format 'TMP:{p} mb' / DPT / HGT keys
once via OnceLock instead of format!()'ing per-cell. Removes ~3.6M
String allocations per f01..f18 chain step across pipeline.rs,
hrrr_points.rs. Same for the wgrib2 :(TMP|DPT|HGT): pattern in
hrrr_points.process_batch (sfc_pattern / prs_pattern OnceLock).
- MapLive preload_forecast: Task.async_stream with max_concurrency=4
replaces the 18-wide Enum.map serial walk. Forecast cache warms
~4× faster after a band change, with ordering preserved.
- grid_tasks: partial composite index on (run_time DESC,
forecast_hour ASC) WHERE status='queued' AND kind='forecast',
matching the Rust claim query's ORDER BY. Drops the old
status-only partial that forced a sort per claim.
**Correctness**
- ContactImportWorker: add Oban unique:[keys: [:import_run_id,
:offset]]. Was missing on a worker whose perform() does a
non-idempotent atomic counter increment — a retry would double-
count imported rows.
- CommonVolumeRadarWorker: x_min..x_max default step is -1 when
x_min > x_max, triggering a runtime deprecation warning. Force
Range.new(_, _, 1) explicitly.
**Cleanup**
- Drop unused tmp_dir parameter from hrrr_point_worker + its
process_batch signature.
Score-grid files now land at `<band>/<iso>.prop` with a 4-byte "PROP"
magic header. Readers still accept the legacy `.ntms` extension and
"NTMS" magic so a rolling deploy doesn't invalidate any file already
on the shared NFS mount — legacy files age out through normal
retention.
Applied both sides of the seam: Elixir ScoresFile + regex parsers,
Rust scores_file writer + decoder. Updated the comments in all
modules that mention the extension (NotifyListener, Reconciler,
gefs_fetch_worker, map_live) and the runbook diagram. talos5 is a
DB host now, not a Rust worker — corrected the runbook accordingly.
Convert every context/worker upsert that used the catch-all
`:replace_all_except` form to the explicit `{:replace, [:col1, ...]}`
form. Reviewers can now see exactly which columns an upsert overwrites,
and adding a new column to a schema no longer silently opts it into the
update path.
Behaviour is preserved bit-for-bit: each new explicit list contains
every column the old `:replace_all_except` would have overwritten.
Touched:
- Microwaveprop.SpaceWeather (Kp / F10.7 / X-ray shared helper)
- Microwaveprop.Ionosphere (observation upsert)
- NexradWorker, HrrrNativeGridWorker (insert_all grids)
- CommonVolumeRadarWorker, RadarFrameWorker (per-contact stats)
Also pins the conflict behaviour for the ContactCommonVolumeRadar
upsert path in RadarFrameWorkerTest so a future column addition that
isn't reflected in the explicit list fails loudly.
Wrap a Task.Supervisor in a PartitionSupervisor (one partition per
scheduler) and route the four sustained async_stream callers through
`{:via, PartitionSupervisor, {Microwaveprop.TaskSupervisor, self()}}`.
Concurrent work — the hourly PropagationGridWorker pulling f00-f18
HRRR range downloads, the GEFS worker scoring its grid, and the
Recalibrator's 20-way positive/negative fan-out — no longer funnels
through a single supervisor PID.
Light/one-shot Task.async + Task.start sites (hrrr_client surface/
pressure fan-out, application boot warmup, weather fire-and-forget)
are left alone; partitioning only helps under sustained concurrency.
Wraps the hourly grid_tasks seed with
[:microwaveprop, :propagation, :grid_worker, :perform] so Prometheus
can see duration, success, and failure for the chain-seed cron.
Emits a :seeded event with the queued_tasks count and an :exception
event on GridTaskEnqueuer failure so silent seed errors show up in
the existing PromEx dashboards instead of dying as a lone Logger.info.
IemClient.fetch_asos returns 24-288 rows per station per call, each
previously triggering an individual UPDATE-conflict round-trip via
Weather.upsert_surface_observation/2. On the Turing Pi 2 Postgres
node that per-row latency dominates ingestion time.
Add Weather.upsert_surface_observations/2, a bulk variant that collapses
the rows into a single Repo.insert_all with the same
update-only-when-changed on_conflict predicate and (station_id,
observed_at) conflict target. Switch WeatherFetchWorker to use it.
The Microwaveprop.Weather.GridCache ETS table grew unbounded — each
hourly PropagationGridWorker run plus peer broadcast_put added ~92k
points per forecast hour, so long-lived pods were strong OOM
candidates. GridCache already exposed prune_older_than/1 but nothing
called it.
Adds an Oban worker on the :propagation queue (lower priority than
the grid chain) that prunes entries older than 3 hours. Scheduled
hourly at :15 in dev, prod, and the base crontab.
CommonVolumeRadarWorker and MechanismClassifyWorker were both
returning :ok on upstream failures, so Prometheus job-failure counters
stayed at zero during multi-hour NEXRAD outages and classifier bugs
went unnoticed.
- CommonVolumeRadarWorker: distinguish permanent (4xx) from transient
errors using the same pattern as RadarFrameWorker. Permanent errors
still mark :unavailable + :ok so the backfill stops re-queueing them.
Transient errors return {:error, reason} and leave radar_status alone
so the next retry can succeed.
- MechanismClassifyWorker: keep the row-status :failed update so
operators can see which contacts blew up, but return
{:error, inspect(e)} from the rescue instead of swallowing it as :ok.
Rework of d61fbd3's dialyzer suppression: the 4 warnings from
LiveTable.LiveResource's macro expansion are now fixed at the
root rather than hidden via .dialyzer_ignore.exs.
Changes:
- Delete .dialyzer_ignore.exs and remove ignore_warnings from
mix.exs. No more hidden suppressions.
- New MicrowavepropWeb.LiveTableResource shim that wraps
use LiveTable.LiveResource and overrides:
* maybe_subscribe/1 — explicit :ok = on Phoenix.PubSub.subscribe/2
(previously discarded, tripping :unmatched_return).
* handle_info/2 — explicit _ = on File.rm, Process.send_after.
Switch all 4 LiveTable-using LiveViews (contact_live/index,
beacon_live/index, admin/contact_edit_live, user_management_live/index)
to use MicrowavepropWeb.LiveTableResource instead.
- New priv/dep_patches/live_table-0.4.1.patch adds _ = in front of
LiveTable.LiveSelectHelpers.restore_live_select_from_params/2 in
the dep's macro-expanded handle_params/3. The call's return was
silently discarded, tripping the fourth warning per LiveView.
- New lib/mix/tasks/deps.patch.ex applies every
priv/dep_patches/*.patch to its target dep idempotently after
mix deps.get. Wired into the :setup alias + overridden
mix deps.get so the patch survives cache regeneration in CI.
- Other modified files in this commit are the spec-coverage
additions from the parallel agent pass (beacons.ex,
commercial.ex, propagation.ex, weather.ex, narr_client.ex,
run_timing.ex, 3 workers) — tighter specs for bounds, tuple
shapes, schema-typed params. Dialyzer remains at 0 after
the changes.
Upstream TODO: send a PR for the live_table `_ =` fix. Once
merged and released, drop the patch + mix task + bump the dep.
mix dialyzer --format short | grep ^lib/ | wc -l -> 0
mix test: 2165 tests, 2 pre-existing flakes (MapLive timestamp +
PropagationPrune ScoresFile), 0 regressions.
Fixes flagged by the code-reviewer agent's pass over the session's
commits (cc9220b..7b78a25):
- Propagation.warm_cache_and_broadcast/2 now uses ScoresFile.read/2
directly and returns {:ok, :ok} | {:error, :enoent | :invalid_format}.
Previously it called ScoresFile.read_bounds/3 which silently returns
[] on missing/corrupt files, poisoning ScoreCache with an empty grid
that the reconciler couldn't heal.
- NotifyListener.warm_band/2 and ScoreCacheReconciler.warm_one/2 now
pattern-match {:error, reason} and skip (log, return :error) instead
of caching empty. rescue clauses kept as defense-in-depth for
unexpected faults in PubSub.broadcast / ETS writes.
- ScoresFile.extract_points/2 promoted to @doc public — callers that
need to distinguish missing file from empty grid can feed read/2
payloads here themselves.
- Weather.build_grid_cache_row/4: replaced || fallbacks with prefer/3
helper (Map.fetch) so a legitimate persisted ducting_detected: false
is not clobbered by a derived-from-sounding true.
- Weather.hrrr_data_fully_present?/1 @spec tightened from map() to
Contact.t() | field-constrained map, plus is_nil(qso_timestamp)
guard so callers with partial contacts get a clean false rather
than a HrrrClient.nearest_hrrr_hour/1 crash.
- AdminTaskWorker.native_derive bulk-UPDATE: chunk reduced 2000 → 500
and wrapped in try/rescue with per-row fallback on Postgrex errors
so a single bad row doesn't kill the remaining 1999 in its chunk.
- Runbook FM3 rewritten to match the actual code path (no rescue;
explicit {:error, _} pattern match). FM5 clarifies the surviving
PropagationGridWorker is a cron-fired seed worker, not a fallback
compute path.
- Dialyzer: strict flags added (:error_handling, :unknown,
:unmatched_returns, :extra_return, :missing_return). Baseline
emitted 130 warnings, mostly discarded Task.start/PubSub/Logger
returns; a follow-up will tighten those and backfill @specs.
New tests:
- ScoreCacheReconciler GenServer lifecycle: run_on_start true/false,
interval_ms rescheduling, info-level log line.
- Weather.hrrr_data_fully_present?/1: nil qso_timestamp returns false.
- Weather.build_grid_cache_rows/2: explicit ducting_detected: false
on profile beats derived true from sounding params.
- RadarFrameWorker: pins the NexradClient "NEXRAD n0q HTTP <code>"
error string contract so permanent_error?/1 classification doesn't
silently regress if the client's error format changes.
1. GridCache: auto-release fill lock when the claimer process crashes.
claim_fill/1 + release_fill/1 go through the GenServer so the
server can Process.monitor the caller and clean up the ETS entry
on :DOWN. Clear/0 now resets both the data table and the lock
table. Fixes a latent bug where a crashed fill leaked the lock
indefinitely, preventing every subsequent /weather mount for that
valid_time from claiming and leaving cache cold.
2. RadarFrameWorker: distinguish permanent vs transient fetch errors.
404 from the IEM n0q archive is permanent (file will never exist)
and marks contacts :unavailable as before. Any other error shape
(5xx, timeout, transport failure) now returns {:error, reason}
so Oban retries — previously those also pinned contacts at
:unavailable after a transient outage.
3. AdminTaskWorker.native_derive: replace per-row Repo.update_all
(N round-trips + N fsyncs) with one UPDATE ... FROM unnest(...)
per 2000-row batch. For the 10k-profile budget this is one
network round trip per chunk instead of 10k, and one fsync per
chunk instead of 10k. Restructured the clause to separate
derivation (pure) from persistence (I/O).
All three changes are test-covered (grid_cache_test auto-release
test, radar_frame_worker_test 5xx + transport tests, existing
admin_task_worker_test native_derive coverage exercises the new
bulk path). Also drops the scorer_diff no-op test that was
verifying the clause removed in 61da51c.
- AdminTaskWorker: remove scorer_diff no-op clause (propagation_scores table
was dropped pre-cutover; queue is drained).
- Weather: remove load_weather_grid_from_db/1 fallback — Rust writes
ProfilesFile for every forecast hour, so the DB path was unreachable
in practice and loaded stale pre-cutover data when it fired.
- Weather.build_grid_cache_row/4 now prefers persisted fields from the
ProfilesFile profile map (surface_refractivity, min_refractivity_gradient,
ducting_detected, duct_characteristics) over re-deriving from the raw
profile, matching the old DB-path semantics.
- NotifyListener: wrap per-band warm in try/rescue so one corrupt or
mid-rename .ntms file doesn't abort the remaining bands. Failures log
a warning with band + valid_time; successes still emit one info line.
- weather_grid_test: rewrite insert_hrrr_profile helper to write
ProfilesFile directly and drop the "only returns points on 0.125 grid"
test (filter was a property of the deleted DB fallback; Rust writes
only grid points by construction).
