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.

parse_cdo_row/1 assumed cdo -outputtab,code,lev,value would always emit
numeric codes in the first column, but Debian's cdo 2.5.1 (the version
in the prod container) emits mixed output:
- 'codeNN' with a literal 'code' prefix for most GRIB1 parameters
- Short GRIB1 names for a few: 2tag2 (PRES sfc), saip (DPT 2m),
tpag10 (HGT)
Result: every row fell through to :error, yielding a 'no parseable
values' error and 986 discarded NarrFetchWorker jobs.
Fix: normalize the code token by stripping 'code' prefix when present
and mapping known 2.5.1 short names. UGRD/VGRD intentionally omitted
(no discard evidence yet) — comment documents the add-when-they-surface
plan.
Also exposed parse_cdo_outputtab/1 as @doc false for testability.
Prod cdo 2.5.1 (Debian) emits named shortnames (tpag10, 2tag2, saip, code11…)
where cdo 2.6.0 (Mac) emits var11/var33/etc. The parser only recognized
varNN, so every prod NARR fetch failed with "no parseable values in cdo
output" and all 350 in-flight jobs discarded.
Switch cdo args from `-outputtab,name,lev,value` to `-outputtab,code,...`.
cdo then outputs the raw numeric NCEP GRIB1 parameter code regardless of
version, and @cdo_code_to_name maps that integer to the semantic name we
already use downstream (TMP/HGT/SPFH/…).
Verified by reproducing on both a 2010 NARR file (fixture) and a 2007 file
fetched live — both now emit identical numeric code rows.
Prod hit "no parseable values in cdo output" for a 2007 record.
Without the actual cdo output it's guesswork whether it's a different
parameter-table format, an empty result, or something else. Capture
stderr (stderr_to_stdout: true) and include first 500 chars of output
so the error message has enough signal to diagnose.
Post-2014 contacts with hrrr_status=:unavailable were being dispatched to
NARR, which 404s because NCEI's archive ends 2014-10-02. 14K of the 14.3K
candidates in prod are post-2014 — these are HRRR's responsibility.
- NarrClient.in_coverage?/1 returns true only inside 1979-01-01 → 2014-10-02
- narr_jobs_for_contact and maybe_enqueue_narr (contact_live) bail out of
coverage returning []
- BackfillEnqueueWorker.type_filter scopes :narr to qso_timestamp <
coverage_end so the cron doesn't keep picking post-2014 candidates
After the NARR backfill landed, nothing reachable from the app calls
any of these modules. Net removal: ~2700 lines.
Deleted:
- Microwaveprop.Workers.{Era5Fetch,Era5Submit,Era5Poll,Era5MonthBatch}Worker
- Microwaveprop.Weather.{Era5BatchClient,Era5Client}
- Mix.Tasks.Era5Backfill (superseded by BackfillEnqueueWorker cron)
- Matching test files (~1100 LOC of test)
- era5/era5_submit/era5_poll/era5_batch queue blocks from runtime.exs
- era5_req_options Req.Test stub config from test.exs
Kept (actively used or intentionally preserved):
- Era5Profile schema (the era5_profiles table is the NARR target)
- Era5CdsJob schema + its test (inspection handle on the era5_cds_jobs
table, which retains rows from the failed CDS runs)
- :era5 type key in ContactWeatherEnqueueWorker / BackfillEnqueueWorker
(the symbol still means "historical backfill", just routed to NARR now)
Swapped the one remaining live Era5FetchWorker call site in
contact_live/show.ex's maybe_enqueue_era5 path to NarrFetchWorker
(with NarrClient.snap_to_analysis_hour for the 3-hourly slot).
Test suite: 1513 tests, 0 failures (-50 from the deleted era5 test
files). No compile warnings. Credo clean.
extract_profile_from_file shells out to cdo:
cdo -outputtab,name,lev,value -remapnn,lon=X_lat=Y <merged.grb>
parses the text output (varNNN ↔ NCEP GRIB1 param number lookup),
maps surface records to era5_profiles fields, builds the pressure
profile from each (TMP, HGT, SPFH) triple, and merges in the derived
fields from SoundingParams.derive/1. Returns the same attrs shape as
Era5BatchClient.build_profile_attrs/5 so the existing
bulk_insert_profiles path can ingest NARR rows unchanged.
fetch_profile_at picks records from a fetched inventory, byte-range
fetches each one into a per-record temp file, runs cdo -merge to build
a composite, calls extract_profile_from_file, and cleans up via
try/after.
Drive-by fix: ThetaE.dewpoint_from_spfh/2 returns Kelvin (its existing
test asserts that explicitly). Era5BatchClient was passing that
Kelvin value straight into "dwpc" (Celsius), which would then crash
SoundingParams.compute_refractivity_profile when it called Buck's
saturation-vapor-pressure equation with t=294 instead of t=21. The
bug never surfaced because era5_profiles is empty in production —
no ERA5 backfill has ever succeeded. Fixed in both era5_batch_client
and the new narr_client by subtracting 273.15 in the wrapper. Both
wrappers now have a comment pointing at the K→C conversion.
Test fixture test/fixtures/narr/narr_dfw_2010-06-15_12z.grb is the
spike-captured composite (1.1 MB — Lambert conformal projection
isn't sellonlatbox-subsettable so we can't shrink it further).
parse_inventory walks the wgrib1-format .inv text and returns a
{var, level} -> {byte_offset, length} index, computing each record's
length from the next record's offset (or file_size for the last one).
fetch_inventory does a GET on the .inv URL plus a HEAD on the .grb URL
to learn its size, then delegates to parse_inventory.
Both stubbable via Req.Test (config/test.exs adds narr_req_options
matching the existing era5_req_options / giro_req_options pattern).
Spike fixture at test/fixtures/narr/narr-a_221_20100615_1200_000.inv
backs the parser test — verifies the ("TMP", "2 m above gnd") and
("WVVFLX", "atmos col") records line up with the real bytes.
First slice of the NARR backfill client: url_for/1,
url_for_inventory/1, and snap_to_analysis_hour/1. Pure functions,
no network. Validates that NARR analyses only exist at 3-hourly
slots (00/03/06/09/12/15/18/21 UTC). The byte-range fetch and
cdo-driven point extraction land in follow-up commits per
docs/plans/2026-04-15-merra2-historical-backfill.md.
