Antenna height now drives typical/extended/exceptional range estimates
and viewshed max range via a sqrt(h_m/10) factor clamped to [0.6, 2.0].
Baseline 33 ft matches the existing defaults. Changing the height input
now pushes update_band_info and refreshes the clicked point's detail
panel plus viewshed so the range-estimate line and coverage shape track
the user's actual station height.
Deploy stamp was in Layouts.app's nav but the map page uses a custom
full-screen layout that skips the standard nav, so the info wasn't
visible on the page most users land on. Add a compact
"Deployed 2h ago" under the sidebar's data-timestamp/pipeline-status
block with the full UTC time as a tooltip, matching the shape of
Layouts.deploy_stamp.
Added 5-arity Scorer.score_refractivity/5 that takes bulk_richardson
alongside best_duct_band_ghz. The existing 1.15× boost now only
applies when Richardson is in the stable regime (< 25) — native-
profile duct cells average 8.7-18.4 for ducting vs 38.3 for
non-ducting, so a duct-band reading under turbulent conditions is
more likely to be torn up by mechanical mixing than to carry a
beyond-LOS signal.
Wiring:
- Weather.nearest_native_duct_info/3 returns {ghz, richardson}; the
bare nearest_native_duct_ghz/3 now delegates.
- PathLive and Propagation.score_with_algorithm/7 both pull the
Richardson value into the conditions map alongside best_duct_band.
- Scorer.composite_score/2 reads conditions[:bulk_richardson] and
passes it into score_refractivity/5.
- Backward compat: 4-arity variant and nil Richardson keep the old
unconditional-boost behaviour so existing callers don't regress.
Path calculator conditions map was missing :latitude and
:best_duct_band_ghz. Scorer read them with bracket-notation so the
behaviour was defensively correct but we were leaving signal on the
floor:
- latitude: midpoint of src/dst so `score_season` picks up the right
latitude-based seasonal shift for northern vs southern paths
- best_duct_band_ghz: queried via new Weather.nearest_native_duct_ghz/3
at the midpoint so score_refractivity/4 applies the 1.15× boost
when a native-resolution duct supports the target band
Recalibrator.fit/1 was serialising ~10k per-contact HRRR lookups
(5000 positives + 5000 negatives, one Weather.find_nearest_hrrr each).
Parallelised both sides with Task.async_stream at 20 concurrency —
well under the prod db pool of 30. Cuts a band recalibration from
~minutes of query round-trips to seconds.
Audit pass found two real issues (most agent-flagged items were false
positives — the hrrr_native_profiles composite index exists,
pwat_mm/bl_depth_m are already in the path conditions map, and the
/1.0 in MechanismClassifier is the standard Elixir int→float coerce).
1. Path calculator's 9-point HRRR sampling was running sequentially,
~9× the latency of a single query. Task.async_stream with
max_concurrency: 9 makes them concurrent so path calc pays roughly
one query's worth of time instead of nine.
2. MechanismClassifyWorker's meteor-shower window used hardcoded 2024
peak dates with `%{date | year: peak.year}` projection. That broke
across year boundaries — a Dec 30 contact couldn't match a Jan 4
Quadrantids peak even in-range of the ±3 day window. Switched to
{month, day} tuples and check the peak projected onto year N-1, N,
N+1 so the window works correctly near Dec 31 / Jan 1.
The "Plot path to beacon" action now includes `tx_power_dbm` and
`src_gain_dbi` in the /path query string so the path calculator's TX
side emits the same EIRP as the beacon out of the box. The beacon
schema stores `power_mw` as EIRP already (per Beacons.RangeEstimate),
so we take 10·log10(power_mw), split against a default 30 dBi dish,
and clamp the TX power to a 0 dBm floor so very-low-EIRP beacons
produce a sane gain/power split instead of -10 dBm outputs.
Examples:
10 W EIRP (40 dBm) → 30 dBi dish + 10 dBm TX
100 W EIRP (50 dBm) → 30 dBi dish + 20 dBm TX
100 mW EIRP (20 dBm) → 20 dBi + 0 dBm (clamped)
Path calculator now samples nine HRRR grid cells evenly along the
source→destination line (was three: Source/Midpoint/Destination) so
mid-path ducts that endpoint-only queries missed show up in the duct
count. The UI reports "Duct at N / 9 HRRR points" instead of a binary
flag, and the table lists every sample with its percent-of-path label.
Independent RAOB signal: uses the new `Weather.nearest_sounding_to/3`
to find the closest sounding within 300 km / ±3 h of the midpoint. If
the sounding's `ducting_detected` is true we surface a "RAOB <code>
confirms duct" badge — HRRR under-reads thin surface ducts that
soundings resolve, so the two signals together are the right
cross-check for live duct prediction.
Distance formatting: all km values on the path results (top Distance
summary, sounding "km from midpoint") now render as
`123 km (76 mi)`; under 10 km we keep one decimal so near-LOS paths
don't round to zero.
Spatial + temporal nearest-RAOB lookup (defaults to 300 km / ±3 h)
joining weather_stations → soundings. Returns the full sounding row
so callers can read the derived ducting_detected / min_refractivity_
gradient fields that HRRR's pressure-level product systematically
under-reads for thin surface ducts.
Prep for the path-calculator enrichment: a sounding within range at
the path midpoint gives an independent duct signal to cross-check
the nine HRRR samples already taken along the path.
Classifies every contact's likely non-LOS propagation mechanism and
persists the result on contacts.propagation_mechanism. Mechanism is
determined in priority order:
1. user_declared_prop_mode (ADIF PROP_MODE from the operator log)
2. EME — moon-ephemeris check, ≥2m band, >1800 km path
3. aurora — Kp≥5 + high-lat path, 50-432 MHz
4. sporadic-E — foEs × 5 ≥ band_mhz, 400-2500 km path
5. meteor_scatter — ±3 days of a shower peak, VHF/UHF
6. rain_scatter — common-volume radar heavy rain, 5-11 GHz ≤800 km
7. tropo_duct — HRRR native_best_duct ≥ band or ducting_detected
8. line_of_sight — ≤50 km path
9. troposcatter — default
Persisted via MechanismClassifyWorker (queue: :mechanism, unique on
contact_id). Submit-time enqueue path includes :mechanism by default;
BackfillEnqueueWorker cron now handles :mechanism alongside existing
types so prod continuously backfills any contact with
propagation_mechanism_status in (:pending, :queued, :failed). Also
added :radar to the cron's type list so common-volume radar backfill
runs automatically rather than only via `mix radar_backfill`.
New modules:
- Microwaveprop.Propagation.MoonEphemeris — Meeus low-precision moon
position, accuracy ±1° — enough for the mutual-visibility EME test
- Microwaveprop.Propagation.MechanismClassifier — plug-in priority
chain over the evidence map
- Microwaveprop.Workers.MechanismClassifyWorker — assembles inputs
from HRRR / native profiles / common-volume radar / solar_indices /
ionosonde + calls the classifier
ADIF importer now reads PROP_MODE into user_declared_prop_mode so
operator-tagged mechanisms (EME/ES/MS/RS/AS/AUR) become ground truth.
Ran recalibrate_algo.py against the full local prop_dev (81,994 contacts,
18.6M HRRR rows) and derived per-band composite weights for the nine
bands with >=200 matched contacts. Moisture (dewpoint/PWAT/surface N)
is consistently beneficial through 5.76 GHz, reverses at 24 GHz; rain
scales sqrt(rain_k) not linearly so 24 GHz gets 0.215 rain weight
instead of the linear-ratio 0.95. 10 GHz stays as the reference band
(defaults); 47+ GHz inherits defaults (n<200).
- BandConfig.weights/1 returns per-band override or default fallback
- @band_configs carries :weights on 222/432/902/1296/2304/3400/5760/24G
- Recalibrator.compute_factors/3 + fit(band_mhz:) band-aware fitting
- Scorer + ContactLive.Show pass band_config to weights/1
- algo.md Part 2d documents the 2026-04-18 analysis + derivation rule
- scripts/derive_band_weights.py turns correlations into weight maps
- report preserved at docs/algo-reports/2026-04-18-recalibration.md
Add a propagation_run_timings table so the wall-clock duration of each
(run_time, forecast_hour) step is queryable long after the run is over.
Keyed by (run_time, forecast_hour) with a status column that captures
whether the step succeeded or bailed out, and an error string on
failure.
PropagationGridWorker stamps every step (ok and failed) via
Propagation.record_run_timing/1. Timing inserts are wrapped in rescue +
changeset-error handling so the instrumentation can never brick the
chain.
Add a "Forgot your password?" flow off the login page. A 24-hour
reset_password token is emailed on request, the landing page lets the
user pick a new password, and all other tokens for the user are
revoked on success.
The request endpoint returns the same flash regardless of whether the
email matches a user so that attackers can't enumerate accounts.
Adopt the handoff design system: navy-slate surfaces with indigo-violet
accent (#6366F1 dark / #5458E3 light), Inter as the UI font, hairline
1px borders, softer corner radii. Add propagation-scale and amateur-band
CSS vars so JS hooks can pull theme-aware colors via getComputedStyle.
Polish: drop table zebra striping for hover-on-base-200 rows with
uppercase small-caps headers, bump .header to text-2xl, tighten nav
spacing with a hairline divider, fix broken text-brand -> text-primary
on the auth screens.
Wire --band-* into contacts_map_hook: resolve once at mount, re-resolve
on data-theme mutation so polylines recolor when the theme toggles.
Previously the map loaded the latest cached valid_time from GridCache,
which can be any +Nh forecast hour the worker has written while walking
f00-f18. Users expect to see current conditions on load, not a forecast
that's ~11 hours out.
Docker final stage bakes BUILD_TIMESTAMP into /app/BUILD_TIMESTAMP via
build-arg (only consumed after mix compile, so earlier layer caching is
preserved). Application.build_timestamp/0 reads the file, falls back to
DEPLOY_TIMESTAMP env, then to compile time. Navbar renders a compact
"Deployed Xm ago" with the full UTC time in the tooltip.
Implements the subset of the isitagentready.com checklist that maps to
real capabilities of this site:
- RFC 8288 Link headers on every browser response advertising
service-doc (/algo), about, privacy-policy, and sitemap.
- Markdown-for-Agents content negotiation: requests with
Accept: text/markdown for / or /algo return real markdown
(curated summary + verbatim algo.md) with x-markdown-tokens hint.
Other paths still 406 — no synthesizing markdown from LiveView HTML.
- Content-Signal directive in robots.txt declaring
search=yes, ai-train=no, ai-input=no.
- RFC 9727 API catalog at /.well-known/api-catalog with the sole
public endpoint (/api/contacts/map) linking status -> /health and
service-desc -> /openapi.json (a new minimal OpenAPI 3.0 spec).
- Agent Skills Discovery index at /.well-known/agent-skills/index.json
listing two skill documents (fetch-contacts, read-algorithm) with
sha256 digests computed at compile time; documents served at
/.well-known/agent-skills/{name}/SKILL.md.
Skipped (don't match actual site capabilities): Web Bot Auth JWKS,
OAuth/OIDC discovery, MCP server card.
Band toggles previously roundtripped through LiveView and rebuilt every
polyline + popup + hover handler on each click. Now the hook builds one
L.LayerGroup per band once after the initial fetch; toggling is just
addLayer/removeLayer on the map (O(bands), not O(contacts)). Checkbox
and All/None events are handled directly in the hook via delegated
document listeners — no LV roundtrip. Callsign filter still roundtrips
(debounced) since it's cross-cutting, and now iterates pre-built
polylines without recreating them.
The detail page was hard-coding GHz formatting, so 50/144/222/432/902
rendered as 0.1/0.4/0.9 GHz instead of the MHz labels every amateur
operator actually uses. Switch to MHz when band < 1000, keep GHz for
microwave bands.
Also surface band and mode in the header subtitle so the key QSO
metadata is visible before SRTM/terrain enrichment completes (the
elevation-profile block that previously rendered them is gated on
that enrichment).
Both workers had unique: [period: 300] which only dedupes within a
5-minute window. Re-running the enrichment-enqueue script hours or
days later stacked identical jobs in the available queue — we found
~60k redundant weather + 3k redundant hrrr jobs in prod from the
March and April enqueue passes.
:infinity means Oban dedupes against every live job in the states
list regardless of age, so a second enqueue pass is a no-op as long
as the first pass's jobs haven't completed yet.
Vendors canvas-confetti 1.9.3 and wires an ImportConfetti hook on the
alert-success banner that /imports/:id already renders when
run.status == "complete". The hook uses the "realistic look" preset
from confetti.js.org and runs on mount, so it fires exactly once —
when the banner first appears.
apply_valid_rows only matched {:ok, _} and {:error, %Changeset{}}, so when
Radio.create_contact returned {:error, :duplicate, existing} — the race
window where preview flagged a row as new but another writer inserts the
same contact before the worker picks up the chunk — the reduce callback
crashed with FunctionClauseError. Oban retried the chunk, rolling back
the Postgrex transaction and surfacing the DBConnection errors the
operator was seeing.
Treat :duplicate as a silent skip: the row is already in the DB, there
is nothing to insert, and the counter should not double-count the existing
contact as an error either.
SubmitLive now hands off to the async pipeline:
- confirm_csv/confirm_adif → CsvImport.enqueue/2 → push_navigate to
/imports/:id. ADIF preview shape matches CSV, so one enqueue call
serves both.
- allow_upload(auto_upload: false) so bytes only stream when the user
clicks submit. Progress bar + percentage now gated on
entry.progress > 0 and < 100 — invisible during file selection,
only rendered while the actual upload is in-flight.
- Old in-page csv_results / @csv_result / reset_csv removed; the
/imports/:id page replaces them.
New ImportLive at /imports/🆔 subscribes to 'csv_import:<id>' PubSub,
shows total/processed/imported/refined/error counters in a daisyUI
stats grid, progress bar, status badge, and a collapsed errors table
when error_count > 0. Missing or malformed run_id redirects to /submit
with a flash.
7 new frontend tests (5 ImportLive, 2 updated SubmitLive), 1902 total,
credo clean.
For large CSVs (e.g. the 34k-row ARRL dump), the synchronous commit
path blocked for minutes and a crash mid-commit left no audit trail.
Refactor to run inserts + enrichment enqueues via Oban.
- New import_runs table: stores preview rows + running counters (total,
processed, imported, refined, error) + status + errors map + timing.
- New :contact_import Oban queue (limit 4) + ContactImportWorker.
Args: {import_run_id, offset, limit}. Each chunk (100 rows) inserts
its slice via CsvImport.commit_rows/1, atomically increments counters
in one update_all, flips status, and broadcasts progress on
'csv_import:<id>' PubSub topic.
- CsvImport.commit_rows/1 extracted from commit/1 (back-compat preserved).
New CsvImport.enqueue/2 persists the run + dispatches N chunk jobs.
Also: submit page copy updated from '902 MHz and up' to '50 MHz and up'
matching the band allowlist expansion done earlier.
LiveView UI for /imports/:id is a separate commit.
57,186 prod contacts stored pos1/pos2 with 'lng'; 1,133 used 'lon'.
Every Elixir caller carried a `pos["lon"] || pos["lng"]` fallback
— which just caused a SQL widget to silently miscount 98% of contacts
(count_narr_done used `pos1->>'lon'` directly, no fallback, so every
lng-keyed row returned NULL and failed the coverage check).
- Migration rewrites every pos1/pos2 JSONB in place, renaming 'lng' to
'lon' and dropping 'lng'.
- Removes all 20+ `|| pos["lng"]` fallbacks across lib/, workers,
scorer, weather, radio.ex, contact show view, and recalibrator.
- lib_ml/propagation_analyze.ex SQL now reads pos1->>'lon' directly
(was reading 'lng' only, which would have broken after migration).
- priv/repo/import_contacts.exs one-time seed script now emits 'lon'
with string keys, matching production shape.
- Test fixtures in 4 test files normalized to 'lon'.
- Two lng-characterization tests deleted — nonsensical post-normalize.
- Updated notebook + old import_weather script to match.
- JS hook contact_map_hook.ts TypeScript type narrowed to 'lon'.
Visitor geolocation already flows via the Cloudflare CF-IPLatitude /
CF-IPLongitude headers into the session; MapLive centers the map on
the visitor's location (or DFW as fallback). Add a banner that appears
above the map when those coords are outside the CONUS bbox
(lat 24.5-49.5, lon -125 to -66.5), letting overseas visitors know
propagation data won't be available at their location yet.
Map still centers on the visitor's actual location — this is a note,
not a re-center. Banner is fully absent from the DOM when not needed
(:if conditional).
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.
count_narr_done/0 checked narr_profiles.valid_time within qso_timestamp
± 30 min — but NARR analyses live at 3-hour marks (00Z/03Z/.../21Z) and
NarrClient.snap_to_analysis_hour/1 floors qso_timestamp to the previous
mark before fetching. A QSO at 18:50Z snaps to 18:00Z on the fetcher
side; the profile stored at 18:00Z fell outside the widget's [18:20,
19:20] window, so the status page showed 6/208 done when actual
coverage was 208/208.
Fix: use equality against the Postgres equivalent of the snap
(date_trunc('hour', ts) - make_interval(hours => hour % 3)).
Comment cites NarrClient.snap_to_analysis_hour/1 so future changes keep
them in sync.
Backtest branch's unknown-feature guard was dead code: the if block's
{:error, _} return was discarded and execution fell through, running the
backtest with a just-created atom and writing a report for nonsense
features. Two compounding issues:
- function_exported?/3 returns false for modules not yet loaded in the
BEAM, so even valid feature names triggered the warning path on a
cold VM.
- String.to_atom/1 on caller-supplied strings created unbounded atoms.
Fix: Code.ensure_loaded?(Features) before the check, String.to_existing_atom/1
with rescue (Features exports __info__(:functions) so every valid function
atom already exists), and an explicit early return via a with pipeline so
the error tuple actually leaves the worker.
FreshnessMonitor's comment claimed 'Oban unique constraint on
PropagationGridWorker prevents duplicates' — but the worker declared
no unique: option. During a long outage the monitor's 5-min stale-check
tick would pile up identical jobs (a 2h outage = 24 stacked jobs, each
doing the full f00-f18 HRRR chain).
Put the dedup on the worker (vs. the monitor's insert call) so anything
enqueuing it benefits — FreshnessMonitor, the hourly cron, or a manual
mix propagation_grid run.
unique: [period: 3600, states: [:available, :scheduled, :executing,
:retryable]] aligns with the hourly cron cadence. The seed job args
(%{}) collapse with themselves while chain-step jobs keep distinct
run_time/forecast_hour and remain enqueuable.
build_messages_per_message/3 was slicing the wgrib2 -lola bin output as
a packed float32 stream, ignoring the 4-byte record-length header + 4-byte
trailer that Fortran unformatted records prepend/append around each
message's data block. First value of message 0 came back as ~2.24e-44
(little-endian float32 of the int-16 record length), and every subsequent
message was shifted by 8 bytes so values spilled into neighbouring cells.
Fix: propagate the correct offset math already used by parse_lola_binary/3
(record_overhead = 8, stride = bytes_per_message + 8, data_offset =
msg_idx * stride + 4).
Flipped the characterization test from metadata-only to per-cell physical
asserts (200 K < TMP, DPT < 340 K; DPT <= TMP) and a 0.01 K cross-check
against extract_grid/3 output on the same fixture + bbox. Latent bug —
no production callers of extract_grid_messages*.
Same fix as rtma_client: MrmsClient had a hardcoded req_options/0 —
switched to a Keyword.merge with Application.get_env so tests can stub
HTTP. 13 new characterization tests: cache put/get/clear/broadcast and
worker listing/download/up-to-date paths. Full GRIB2 parse happy path
deferred to the wgrib2 coverage task.
RtmaClient was the only weather client without a Req.Test plug seam —
added the standard req_options() helper matching NarrClient/HrrrClient/
etc. so its HTTP calls can be stubbed in test.
17 characterization tests: URL construction, idx fetch 404/503, hour
truncation, malformed idx, range-GET error propagation, worker's
existing-row short-circuit, client-error propagation. GRIB2 byte
parsing paths deferred to the wgrib2 coverage task.
Status page NARR progress counted `hrrr_status = :unavailable` as the
candidate set, which swept in ~13.6K post-2014 HRRR retry rows and
showed "0 / 13,652". Candidate eligibility is qso_timestamp-based, not
hrrr_status-based — switch both the numerator and denominator to
`qso_timestamp < NarrClient.coverage_end()` so pre-2014 rows are
counted whether their hrrr_status is :queued, :unavailable, or
:complete.
ContactWeatherEnqueueWorker: short-circuit hrrr_points_for_contact/1
for pre-coverage timestamps and mark the contact :unavailable when no
HRRR jobs are built. Was producing a ping-pong where reconcile flipped
pre-2014 :queued → :unavailable and the same cron run flipped it back
to :queued from a rebuilt HRRR job that could never land data.
Makes the 'always recompute' intent explicit by removing the dead-code
short-circuit in add_distance_change — the candidate query already
requires at least one nil pos, so any previously stored distance is
tied to a stale grid/pos pair and must be overwritten.
10K+ HRRR-pending contacts were starving the 200-ish NARR candidates
out of the 500 per-run slot each 30 min because NARR candidates sort
last by the :hrrr_status priority. Drop the cap so every eligible
contact gets enqueued on each cron run; queue concurrency still paces
the actual fetches. Worker keeps supporting an explicit "limit" arg
for ad-hoc runs and tests.
The US 9cm amateur allocation was cut from 3300-3500 to 3300-3450 MHz
in 2020, so 3456 (the legacy weak-signal calling frequency) is no
longer in-band. Move the canonical key to 3400, migrate existing
contacts, and keep 3456 input resolving to 3400 via the
nearest-band snap so historical ADIF/CSV logs still import cleanly.
Expands submittable-contact bands to include 6m, 2m, 1.25m, and 70cm
(as 432 rather than the old 440 placeholder). Each new band gets an
explicit allocation window in BandResolver.nearest_band so ADIF FREQ
fields near the amateur allocations resolve correctly while 60-900 MHz
frequencies outside those windows are still rejected. Microwave
(>= 900 MHz) snapping is unchanged — nearest-band match across the
full @allowed_bands list.
Also adds BandConfig entries for 50 and 222 (tropo-only config, same
pattern as 144/432). Sporadic-E / F2 / meteor scatter modeling is not
yet in scope — ionosphere data is only used to compute an Es readout
on /path for 50/144/222/432.
Safety net for rows that land via direct DB writes (manual fixes, bulk
imports) and bypass Radio.create_contact's grid-resolution requirement.
Runs every hour on the :admin queue with a 500-row per-invocation cap.
Fills whichever side resolves — if one grid is invalid, the other still
gets populated; distance_km is only written when both positions end up
set.
Widen dedup match to 4-char grid prefix so an upload with a longer grid
(e.g. FN42aa25) finds the existing FN42 contact. Within a match, classify
as a refinement when the upload strictly extends the existing grid or
fills a missing mode; as a contradiction (still skipped) when grids or
modes genuinely disagree. Refinements flow through a new preview bucket,
update the existing row in place, and re-enqueue enrichment when the
position changed.
The /contacts LiveTable export produces a 12-column CSV with label-style
headers (Station 1 / Grid 1 / QSO (UTC) / ...) in a different column
order plus extras (id, distance_km, hrrr_status, flagged_invalid,
inserted_at). The old positional import rejected it with "expected 6 or
7 columns, got 12".
Replace the positional parser with header-driven mapping:
- Parse the header row, normalize each cell (downcase + trim), and look
it up in an alias map that covers both the raw field names and the
export labels.
- Required columns: station1, station2, grid1, grid2, band, qso_timestamp
(mode stays optional). If any are missing the header, return
{:error, {:missing_required_columns, [...]}}.
- Unknown columns are silently ignored so the export's extras don't break
round-trip.
- Per-row validation stays the same (changeset errors still reported by
row number).
Existing 6- or 7-column positional CSVs that already have a header still
work — the header parser recognizes `station1`, `station2`, etc.
directly.
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
- /status progress bar, status-by-type card, and internal map keys now
read "NARR" (data-progress-key="narr", narr_candidates/narr_done).
era5_profiles table stays as the DB landing spot (historical artifact).
- BackfillEnqueueWorker cron now passes "era5" in types so pre-2014
contacts whose hrrr_status is :unavailable actually get NarrFetchWorker
jobs enqueued every 30 min. The :era5 type key still maps internally
to NarrFetchWorker via era5_jobs_for_contact/1.
