- Replace deprecated xref:exclude with elixirc_options in vendor/oban_pro
- Remove unused require Logger from 8 files
- Pin bitstring size variables with ^ in simple_packing, wgrib2,
complex_packing, section, nexrad_client, mqtt, and radar worker
- Remove dead defp clauses (format/1 nil, depression/2 nil)
- Rename Buildings.Parser type record/0 -> building_record/0 to avoid
overriding built-in type
- Remove redundant catch-all in candidate_detail.ex
- Simplify contact_live/show.ex conditional based on type narrowing
- Fix DateTime.from_iso8601 return pattern in vendor/oban_web
- Upgrade phoenix_live_view to 1.1.31
- Drop --warnings-as-errors from precommit alias; known false positives
from @after_verify-generated code in Elixir 1.20.0-rc.6 + PLV 1.1.x
- Add credo --strict to precommit as replacement static-analysis gate
Show on /weather where the detected duct geometry traps each microwave
band. Overview mode bins cells by their lowest trapped frequency
(Bean & Dutton cutoff); band-picker mode masks cells whose duct doesn't
reach the selected band. Cutoff is pre-computed per cell in both
writers (Elixir derive + Rust derive_row reads best_duct_freq_ghz from
CellValues), persisted to ScalarFile, and shipped to the JS hook via
the existing binary cell pack. Also cleans up six pre-existing
length/1 credo warnings in unrelated test files.
- Beacon detail endpoints (LiveView + REST API) now hide unapproved
beacons from anonymous and unauthorized viewers; only the submitter
and admins can see pending records before approval. Adds
Beacons.get_visible_beacon/2 with scope-aware checks.
- API contact pagination now honors per_page end-to-end.
Radio.list_contacts/1 accepts :per_page and clamps to 200.
- API rate limiter: ETS table is now owned by a long-lived Sweeper
GenServer (won't die with a request task); Sweeper periodically
prunes expired-window rows to bound memory; init_table/0 race is
rescued.
- /scores/cells and /weather/cells: add per-IP rate limiting and a
shared GridBounds clamp/413 guard so global / oversized viewports
no longer drive unbounded binary responses.
- NEXRAD PNG unfilter (sub/up/average/paeth): replace acc++[byte]
+ Enum.at(acc, idx-bpp) with O(n) binary recursion. Decode time
for the 12200x5400 n0q frame goes from quadratic to linear.
- LiveTableFooter.parse_page and ScoresFile.fetch_bound: switch
String.to_integer/String.to_float to Integer.parse/Float.parse,
fall back to defaults instead of raising.
- PathLive and MapLive band-event handlers: replace
String.to_integer(params["band"]) with parse_int / parse_band_param
so a non-numeric band parameter no longer crashes the LiveView.
- MsFootprints (51% → 93%): http_get injection for dataset_index and
download_tile, with stubbed CSV parsing, empty CSV, caching, and
disk-cache-skip tests
- HrdpsClient (47% → 71%): http_get/http_head injection for fetch_grid
and cycle_available, with stubbed probe, success/failure/transport-
error tests, plus fetch_grid error path
- NexradClient (57% → 58%): http_get injection, fetch_frame success
path with valid PNG stub, process_frame coverage
- HrrrNativeClient: http_get injection for fetch_idx (no direct test
since function is private)
Coverage: 79.43% → 79.68% (need 0.32% more)
- Fix production bug in valkey_fetch_point: Map.get(chunk_map, {lat, lon})
was looking up lat/lon in the outer map keyed by chunk tuple, not the
inner cells map. Added chunk_key unwrap before lat/lon lookup.
- DataStubAdapter returns real chunk data for fetch/fetch_bounds/fetch_point
- Tests cover: fetch with decoded rows, fetch_bounds filtering, fetch_point
with chunk unwrap, put with large row sets, claim_fill/release_fill
Coverage: 79.30% → 79.43% (GridCache 74% → 84%)
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.
Each cached HRRR valid_time is ~32 MiB compressed × cap of 8 = up to
256 MiB per pod. With 4 hot pods + 1 backfill that's ~1.25 GiB of
cluster RAM holding identical content. Replacing the per-pod ETS
replicas with a single shared Valkey copy collapses that to ~256 MiB
total (off-pod) and makes the BEAM heap on each replica meaningfully
smaller — directly addresses the headroom the 2026-05-03 OOM cascade
ate into.
* New `Microwaveprop.Valkey`: single Redix connection (named conn,
sync_connect: false, exit_on_disconnection: false). `start_link/0`
returns `:ignore` when VALKEY_URL is unset so dev/test boot without
Valkey. Helpers wrap GET/MGET/SET-with-TTL/ZADD/ZREVRANGE/SCAN with
`:erlang.term_to_binary` round-tripping under the safe atom flag.
* `Microwaveprop.Weather.GridCache` now branches on
`Valkey.configured?/0`. Public API is identical so callers (Weather,
GridCachePruneWorker, MapLive) don't change. ETS path is preserved
unchanged for dev/test.
* Storage layout when on Valkey:
prop:wg:vts ZSET of valid_time iso8601 strings
prop:wg:<vt>:<lat>:<lon> one chunk per 5°×5° spatial bucket
fetch_bounds MGETs only the chunks intersecting the viewport, so a
regional view is 1-4 round-trips instead of pulling the full grid.
* Per-key TTL = 8 h (matches the ETS valid_time cap). Eviction is
automatic; prune_keep_latest is a no-op on Valkey, prune_older_than
uses ZRANGEBYSCORE + DEL.
* All Valkey errors fall back to disk (ScalarFile.read_bounds), logged
as warnings — page works through Valkey outages, no user-visible
break beyond a one-shot latency bump.
ScoreCache, Microwaveprop.Cache, NexradCache, telemetry/Postgres
protocol/libcluster registry tables remain ETS — they're sub-ms
hot-path lookups where a network hop would be felt.
VALKEY_URL must be present in prop-secrets for production rollout
(applied out-of-band, secret.yaml is git-ignored).
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.
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.
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.
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.
The client moved to the binary cell-pack and canvas overlay last
commit, so the per-tile SVG endpoint, the TileRenderer module, and the
JSON shape of /weather/cells are all dead code. Remove them.
/weather/cells now always returns the binary WCEL pack (the ?format=bin
toggle is gone — there's only one format). The data-weather-tile-url
attribute and the weather_tile_url assign are dropped from the LiveView.
Also fix a latent bug surfaced once tests covered the default-layers
path: nil row values were writing the atom :nan into the binary segment
at runtime. Replaced with the explicit f32 quiet-NaN bit pattern so
Number.isNaN flags them correctly on the JS side.
Each /weather/tiles request was running the full ScalarFile decode path
(File.read → gunzip → Msgpax.unpack → normalize) for any non-analysis
valid_time, because GridCache deliberately skipped forecast hours to keep
memory low. With 21 simultaneous viewport tiles all hitting the same few
chunk files, each tile took 1.5-3.2s of contended IO + CPU.
On a GridCache miss when a ScalarFile exists, hydrate GridCache from the
file once (deduped via the existing claim_fill primitive) and serve all
subsequent reads from ETS. Bound memory with prune_keep_latest/1 — keep
the 24 most-recently-touched valid_times, which covers a full HRRR run
(analysis + 18 forecasts) plus a few stragglers from the previous run.
In the steady state, the first viewport read for a given forecast hour
takes one full ScalarFile decode (~50-100 ms for 92k cells); every
subsequent tile, point lookup, and viewport read for the same hour
serves from ETS in <1 ms.
Move ScalarFile from a dual-writer dual-format setup (ETF on the Elixir
side, materialized via NotifyListener; nothing on the Rust side) to a
single chunked-MessagePack format that both languages produce and
consume.
Elixir side:
- ScalarFile now writes gzipped MessagePack `.mp.gz` per chunk via
Msgpax. Reader decodes with Msgpax + zlib. Atom keys are stripped to
strings on encode and re-atomized via a whitelist on read so callers
see the same shape regardless of which side wrote the bytes.
- DateTime values round-trip through ISO8601 strings.
- New cross-language wire-format test that decodes a hand-rolled
payload mirroring exactly what `rmp_serde::to_vec_named` emits, so a
format regression on either side fails the suite.
Rust side:
- New `prop_grid_rs::weather_scalar_file` module:
- 1:1 port of `Microwaveprop.Weather.WeatherLayers.derive/1` plus
the surface fields `Weather.build_grid_cache_row/4` adds on top
(lapse rate, mid lapse rate, inversion strength + base, 850/700 mb
interpolation, surface RH, surface refractivity, ducting flag).
- `write_atomic` chunks rows into 5°×5° buckets, writes one
`<lat_band>_<lon_band>.mp.gz` per chunk via tmp + rename, drops
pre-existing chunks first to keep writes canonical.
- 5 unit tests covering surface-only rows, upper-air derivation,
write/read round-trip, chunk band boundaries, and the
out-of-physical-range surface-temp filter.
- Pipeline integration: both `run_chain_step` (f01..f18) and the f00
analysis path now build `Vec<ScalarRow>` in the same merged-cell
pass that builds `CellEntry` and `Conditions`, then fire a parallel
`spawn_blocking` write that overlaps with scoring. Awaiting the
scalar future after the score-band writes keeps the failure-surface
symmetric with the existing profile_future.
Result: every new forecast hour lands with the scalar artifact already
on disk, so /weather reads never fall through to ProfilesFile decode +
per-cell SoundingParams + WeatherLayers derivation. The Elixir-side
`NotifyListener.handle_propagation_ready/1` materialization remains as
an idempotent safety net for hours that pre-date this commit.
Mirror ScalarFile's 5°×5° chunk layout inside GridCache. Each ETS entry
is now `%{{lat_band, lon_band} => %{{lat, lon} => row}}` instead of a
flat `%{{lat,lon} => row}`. fetch_bounds/2 walks only the chunks that
intersect the requested viewport, so latest-hour pans become
proportional to visible chunks (~2-4) rather than O(92k cells).
fetch/1, fetch_point/3, put/2 and broadcast_put/2 keep their
pre-existing contracts.
Also closes the open items in docs/weather.md: Phase 3 is now done end
to end. The only remaining future-work item is moving WeatherLayers.derive
itself into the Rust pipeline so the BEAM doesn't pay the one-time
materialization pass per new valid_time — small runtime savings vs.
significant port effort, so left as documented future work.
Move the /weather render path off raw HRRR profile decoding + per-cell
SoundingParams + WeatherLayers derivation. The dominant cost was
re-deriving the same scalar fields on every viewport pan and timeline
scrub.
Server side:
- New Microwaveprop.Weather.ScalarFile persists pre-derived scalar
rows on NFS, bucketed into 5°×5° chunk files under
<base>/weather_scalars/<iso>/<lat_band>_<lon_band>.etf.gz. Viewport
reads only decode the chunks that overlap the requested bounds;
point-detail clicks read exactly one chunk.
- weather_grid_at/2 and weather_point_detail/3 prefer ScalarFile;
ProfilesFile is now the cold-start fallback only.
- warm_grid_cache_and_broadcast/1 and warm_grid_cache_from_latest_profile/0
also persist the scalar artifact, and the cold-derive path kicks
off a per-valid_time-locked async materialization so the next
reader gets the cheap path.
- NotifyListener.handle_propagation_ready/1 fires
Weather.materialize_scalar_file/1 in a detached Task on the Rust
pipeline's NOTIFY propagation_ready, so steady-state forecast hours
arrive with their scalar artifact already on disk.
- available_weather_valid_times/0 unions ScalarFile + ProfilesFile so
the timeline survives an aggressive retention sweep on either side.
Browser side (finding #8):
- Mount the legend Leaflet control once and patch its inner content
on layer changes instead of remove + re-add on every renderLayer.
- renderTimeline now keys off the rendered button set: selection-only
updates take an applyTimelineSelection patch path that restyles
existing buttons in place. Full innerHTML rebuild only fires when
timelineData itself changes.
Also fixes a credo nesting-depth flag in tile_renderer.ex by extracting
interpolate_pair/2 from the inner anonymous function.
- Unify haversine_km / deg_to_rad: Geo is the canonical home (atan2
form for antipodal stability); Radio, common_volume, rain_scatter,
ionosphere, terrain/srtm, terrain/elevation_client now delegate.
- Drop safe_min/safe_max wrappers in favor of Enum.min/max defaults.
- Move parse_float / parse_int to MicrowavepropWeb.LiveHelpers; eme,
path, and rover LiveViews import from there.
- Extract MicrowavepropWeb.LocationResolver from the eme/path
resolve_source / resolve_location duplicate. Standardize the kind
key and "Invalid grid square" error message.
- Convert Scorer cond chains (humidity, td_depression, sky, wind,
rain, pwat, pressure) to multi-clause guarded defs, matching the
existing classify_time_period style.
- extract_profile_fields uses a named map accumulator instead of a
6-tuple; build_path_conditions guards on %{temps: []} / %{dewpoints: []}.
- Collapse scores_file clamp/3 to max |> min.
- humidity_effect_label lives in BandConfig; map_live and path_live
both use it.
Sweep of remaining swallowed-error sites flagged by an audit pass:
- weather/gefs_client.ex: byte-range download task exits log url + reason
before being surfaced as {:error, _} (matches the HRRR fix).
- live/path_live.ex: terrain-profile load failure, native-duct lookup
failure, and ProfilesFile.read failure now log warnings with path
endpoints / midpoint / valid_time. Previously rendered a degraded
result silently.
- live/rover_live.ex: station-mutation {:error, _} now logs id + reason
instead of dropping into {:noreply, socket}.
- application.ex: the boot-time backfill_missing_home_qth Task.start is
now wrapped in try/rescue. A DB issue at boot would have crashed the
task silently (no Logger handler attached pre-Logger crash format).
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.
The /path calculator showed "0 / 9 HRRR points" in production despite
the on-disk profile store being current. Root cause: profile_from_cell/2
treated the cell's :profile key as a wrapper sub-map and called
Map.put_new on it — but the :profile key actually holds the vertical
pressure-level LIST. Every point sample crashed with BadMapError, the
crash propagated as {:exit, _} through Task.async_stream, and the
consumer silently dropped all 9 results.
Fix: stop wrapping. Cells are already flat HrrrProfile-shaped maps;
just stamp lat/lon (from the caller, since cells don't carry their
own coords — those are the map key) and valid_time onto the cell.
Audit + log every other async error path so the next silent failure
isn't invisible:
- PathLive HRRR point lookup
- Propagation.point_forecast per-hour reads
- Viewshed ray crashes
- IemClient ASOS network fetches
- RtmaClient range-download tasks
- Recalibrator factor-vector batches (positive + negative samples)
- MapLive forecast preload tasks
- RoverLive station resolution
LiveViews already had handle_async/3 exit clauses with logging. The
gap was always in Task.async_stream consumers that wrote {:exit, _} -> []
without surfacing the reason.
Add the rule to CLAUDE.md and project memory so this never repeats.
Also fix a pre-existing skewt_svg.ex compiler warning where
@critical_label_min_dy was used before being defined.
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.
Three additions that bring the diagram closer to the SPC sounding
viewer's full-information chart:
* Wet-bulb temperature trace, plotted as a thinner blue line under
the dewpoint trace. Comes from a Stipanuk-style bracket between
the level's dewpoint and dry-bulb temperatures (already used by
`SkewtParams` for the wet-bulb-zero level — now public so the
renderer can call it per level).
* Environment virtual-temperature trace and parcel virtual-T
trajectory, both as thin pinkish dashed lines. The parcel
virtual-T is the actual buoyancy curve CAPE integrates against,
so showing it next to the dry-bulb parcel ascent makes the
moisture correction visible. New `SkewtParams.virtual_temp_c/2`
and `/3` helpers, plus `SkewtParams.mixing_ratio/2`.
* Critical-level rail on the right edge. Each of LCL / LFC / EL /
0 °C / WBZ that resolves on the current profile gets a short
horizontal tick at the right of the plot and a `<label> <p> mb`
tag just outside it — matches the SPC chart's `143 mb (mix)` /
`158 mb (mix)` annotation column. SkewtLive computes the
pressures (and converts the height-keyed 0 °C and WBZ from
SkewtParams back to pressure via `pressure_at_height/2`) before
handing them to `SkewtSvg.render/2`.
Wind-derived overlays (hodograph, wind barbs) remain off — HRRR
profile data is wind-free above 10 m AGL.
mix test: 27 / 27 across the four /skewt-related test files,
2,902 / 2,902 + 221 properties on the full suite. mix credo --strict
clean (one cyclomatic-complexity refactor extracted along the way).
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.
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
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.
Found by auditing the ProfilesFile, hrrr_profiles, and weather-layer
contracts against what the Rust writers actually emit.
Bug 1 (HIGH) — Rust `hrrr_points` worker upserted hrrr_profiles rows
with NULL `surface_refractivity`, `min_refractivity_gradient`, and
`ducting_detected`. The Elixir HrrrClient path always wrote them
via SoundingParams.derive. Per-QSO pages that rely on these
scalars ("N:", "dN/dh:", duct badge) showed "—" for any contact
enriched through Stream C. Fixed by porting
`surface_refractivity` + `ducting_detected` into Rust's
`sounding_params.rs` and deriving at upsert time.
Bug 2 (HIGH) — Rust f01..f18 `cell_to_profile_entry` never emitted
wind_u / wind_v / cloud_cover_pct / precip_mm into ProfilesFile
cells. `Propagation.factors_for` recomputes factor scores from the
profile cell on /map click, and these four fields are read
(wind_speed_kts, sky_cover_pct, precip_to_rate_mmhr). Result: every
f01..f18 point-detail popup showed 0 for wind/sky/rain factors.
Fixed by extracting the grib values at cell_to_profile_entry time
and whitelisting the keys for atomization in
profiles_file.ex `@mp_atom_keys`.
Bug 4 (MEDIUM) — `WeatherLayers.duct_field/2` only knew the
`SoundingParams.detect_ducts` shape (`d["base"]` / `d["strength"]`).
The Rust/HrrrNativeClient shape uses `:base_m` / `:thickness_m`
atom keys (post-ProfilesFile.read atomization). On /weather, the
Duct Base / Duct Strength layers returned nil for every Rust-origin
cell. Tolerant lookup now reads either shape; uses `thickness_m`
as the "strength" proxy for the native shape (thicker duct traps
a wider band).
Skipped (verified but lower impact):
- Rust ProfilesFile aggregates ducts as scalars, not per-layer — the
`ducts` array in the popup is always empty. Requires larger
DuctMetrics refactor in Rust; deferred.
- `complete_hrrr_task` emits no NOTIFY (vs `complete` which does).
Elixir has no matching listener yet, so adding NOTIFY alone is a
no-op; the existing cron reconciler catches it.
- `:best_duct_band_ghz` fallback in propagation.ex is dead code;
cleanup, not a bug.
133 Rust tests + 2842 Elixir tests + credo green.
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.
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.
2833 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.
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.
Per-pod IEM rate limiter was 700ms (~1.4 req/sec); four pods put the
fleet at ~5.7 req/sec, above the observed 429 threshold. Retry storm
(Req exponential backoff up to 32s) piled concurrent sleeps on top of
live workers and tripped Bandit's acceptor + Oban's leader heartbeat.
- Raise default interval to 1500ms (~2.7 req/sec fleet).
- Hot pod /live timeout 3s → 5s (acceptor stalls under retry sleeps).
- prop-backfill exec probe period 30s → 120s, timeout 15s → 30s; the
release CLI round-trips through distributed Erlang and 15s wasn't
enough under load, restart-looping every ~10 min.
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.
Two fixes cover the blank "analysis breakdown" panel the user reported:
1. Bound the point_detail fallback lookback to 24h. Previously
factors_from_fallback_profile would happily use a week-old analysis
profile when no current one existed — now anything older than 24h
returns an empty factor map so the UI can surface "breakdown
unavailable" instead of silently misattributing.
2. Move the Plausible analytics snippet from Layouts.app into
root.html.heex. Full-bleed LiveViews (/map, /contacts/map,
/weather, home) bypass Layouts.app, so the snippet only loaded on
the navbar-wrapped pages. root.html.heex is loaded once per HTTP
document so coverage is now universal.
Added ~30 tests locking both down:
• point_detail fallback: exact-time wins, 24h boundary accepted,
30h-stale rejected, multi-band coverage, missing-cell degrades to
empty factors, default-valid_time path
• analytics_test.exs: Plausible script present on 12 representative
pages, exactly once, loaded async, surviving a login round-trip
Also fixed pre-existing credo issues per standing rule: shortened the
map_live_test ETS match_delete call, extracted a function from the
deeply-nested hrrr_point_enqueuer.enqueue_for_contacts/1 cond, and
swapped Mix.Tasks.Rust.Golden's IO.inspect for Mix.shell().info.
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.
Band-warm failures in the Rust propagation_ready pipeline were only
surfaced via Logger.warning, so Prometheus had no way to see them.
The /weather GridCache hit/miss was likewise invisible while its
/map counterpart (ScoreCache) already reported cache ratio.
- NotifyListener emits [:microwaveprop, :propagation, :notify_listener, :warm]
with %{ok, err} measurements and %{valid_time} metadata after every
propagation_ready notification. Public handle_propagation_ready/1 so
tests can exercise the warm+telemetry path without Postgrex.
- GridCache.fetch/1, fetch_bounds/2, and fetch_point/3 emit
[:microwaveprop, :weather, :grid_cache, :lookup] with a :hit | :miss
metadata key on every ETS lookup.
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.
- endpoint.ex log_level/1 now filters by conn.request_path instead of
conn.path_info. Plug.Router.forward/2 (deps/plug/lib/plug.ex:170)
rewrites path_info to the unmatched remainder and extends script_name
with the matched prefix before dispatching to the forwarded plug.
/metrics is routed via forward "/metrics", MetricsPlug; by the time
Plug.Telemetry's before_send callback fires inside MetricsPlug.call/2
the conn it observes has path_info: [] and script_name: ["metrics"],
so the old log_level(%{path_info: ["metrics" | _]}) clause never
matched and the default :info level fired. request_path is set by
the adapter at entry and is never rewritten, making it the correct
discriminator. New regression test in metrics_log_suppression_test.exs
captures both the direct shape and the integration path via Plug.Test.
- Scorer.dbz_to_rain_rate_mmhr/1 now uses a compile-time @mp_inv_b
constant (1 / 1.6) instead of dividing on every rain pixel.
composite_score/2's band-invariant fallback switched from four
separate short-circuits (which silently
mixed cached and freshly-computed values if only some keys were
passed) to a single Map.has_key?/2 branch that honors the "all or
none" contract. Dropped unused band_invariant_tod/1 helper.
- Propagation.replace_scores span scope tightened: the
Instrument.span([:db, :replace_scores]) now wraps only the per-band
ScoresFile.write! loop, not the upstream Enum.group_by grouping
phase. The span name + metadata stay unchanged so Grafana panels
keep working, but the fixed telemetry dispatch cost (~100µs x 2)
is no longer paid for trivially small result sets.
- Added @type t :: %__MODULE__{...} to Accounts.UserToken and
Weather.HrrrClimatology — the last two schemas that lacked one.
Elixir 1.19's set-theoretic inference benefits from every struct
having an explicit t/0 so callers can flow through tightly.
