Replace the two-script Python pipeline (analysis report + Elixir-source
emitter) with a single `scripts/recalibrate.py` that fits per-band
weights from PSKR spot density (VHF/UHF) and contacts↔HRRR correlations
(microwave), writing `priv/algo/band_weights.json` as a machine-readable
artifact. A new Elixir BandWeights module loads this JSON once via
`:persistent_term` cache; BandConfig.weights/1 consults it before falling
back to in-source overrides or global defaults. The script never touches
Elixir source — recalibration is now `python3 scripts/recalibrate.py`
followed by an app restart.
POST /api/v1/beacon-monitor/measurements accepts one measurement per
integration window from a propmonitor client, authenticated by the
BeaconMonitor token. Records noise floor, signal peak/avg dBFS, SNR,
signal-active-fraction, gain, and frequency for later correlation
against weather and propagation scores.
Beacon UUID must resolve to an approved + on-the-air beacon (404
otherwise — the client drops 404s without retry). Retries with the
same (monitor, beacon, measured_at) are idempotent: a unique index
makes the second insert a 409. Every accepted upload stamps the
monitor's last_seen_at — measurements *are* the heartbeat.
MonitorAuth is a separate plug from the user API-token Auth plug;
monitors are not users. The rate limiter buckets each monitor by id so
retry storms after a 5xx don't burn the shared anon-IP bucket.
Adds bearer-token authenticated REST API at /api/v1 covering every
action a non-admin user can perform on the website: contact + beacon
submission, beacon-monitor management, propagation queries, profile
read/update, and self-service API token issuance/revocation.
Security: SHA-256-hashed bearer tokens (mwp_ prefix, plaintext shown
once at creation), RFC 9457 problem+json error responses, RFC 9651
RateLimit-* headers backed by an ETS bucket (600/min per token,
60/min per anonymous IP, 30/min on /auth/tokens), private-contact
filtering by viewer.
Docs at docs/api/README.md (prose reference) and docs/api/openapi.yaml
(OpenAPI 3.1 spec covering every endpoint, response, and schema).
Tests: 124 new tests across schema, plug, error renderer, rate
limiter, fallback, and every controller. 16/17 API modules at 100%
line coverage; FallbackController at 87.5% (one defmodule line, an
Erlang-cover artifact for action_fallback-only modules).
`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.
Two related changes to the contact detail page:
1. The "Flagged invalid" badge was wrapping to two lines on
narrow widths because the daisyUI badge has no explicit
no-wrap class. Add `whitespace-nowrap`, drop the redundant
capitalization on "Invalid", and append the flagger's
callsign so the badge reads "Flagged invalid by W5XYZ".
Hover tooltip carries the timestamp.
2. New `flagged_by_user_id` + `flagged_at` columns on contacts.
`Radio.toggle_flagged_invalid!/2` now takes the admin User
doing the flagging; on unflag it clears both fields so a
subsequent re-flag gets a fresh attribution and the badge
never shows a stale flagger.
3. `Radio.delete_contact!/1` + a Delete button next to Flag.
Admin-only, gated in both the event handler and the template.
Uses LV's `data-confirm` for the destructive-action prompt.
All FK references to `contacts` already declare
`on_delete: :delete_all` (terrain_profiles, contact_edits,
contact_common_volume_radar) so a single Repo.delete!
cascades cleanly.
Subscribes to mqtt.pskreporter.info:1883 over plain TCP and folds
every reception report into hourly aggregates per
(band, sender_grid_4, receiver_grid_4). Each spot is the empirical
"propagation actually occurred on this path right now" signal we'll
correlate against HRRR atmospheric state to recalibrate the scoring
weights. Aggregating at the path-hour bucket collapses 50-reporter
QSOs to one row instead of 50.
Topic filter anchors on USA (DXCC 291) on either sender or receiver
side so the broker pre-filters out everything outside our HRRR
domain. Bands subscribed: VHF and up (6m, 2m, 70cm, 23cm, +
microwave) — HF is dominated by ionospheric propagation, which this
project doesn't model.
Pskr.Client cluster-elects a singleton via :global.register_name —
all replicas start the GenServer but only one connects to MQTT;
the rest stay in :standby and watch for the leader's nodedown to
re-run election. Off in dev/test, on by default in prod
(PSKR_MQTT_ENABLED=false as kill-switch).
Pskr.Aggregator buffers in memory keyed by Pskr.path_key/1 and
flushes every 60s via Repo.insert_all/3 with an additive
ON CONFLICT (count summed, SNR envelope by GREATEST/LEAST,
modes unioned via unnest+DISTINCT). Idempotent across overlapping
flushes and across leader handover.
Dockerfile sets BUILD_WITHOUT_QUIC=1 — emqtt's transitive quicer
dep wants CMake + OpenSSL headers we'd otherwise have to add to
the builder image just to never use QUIC over plain MQTT. Base
image is unchanged; the new dep compiles cleanly into the existing
prop-base runtime.
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).
Renames the rover-location status enum and every label that referenced
it. Existing rows are migrated in place. Also touches the consumers:
- Rover.Location enum + default
- RoverLocationsLive index, status filter, form, show, badges
- Rover.Compute and rover_live (only_ideal_locations → only_good_locations)
- RoverPlanning context candidate filter (status == :good)
- RoverPlanning.Show / Form copy
- All rover-related tests
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.
Oban Pro 1.7.0 ships database-backed workflow tracking, replaces the
generated `uniq_key` / `partition_key` columns with expression
indexes, and adds new partial indexes for query performance.
Switches oban_pro from the vendor/ tree to the licensed `oban` hex
repo (auth already configured via `mix hex.repo`). vendor/oban_pro
deleted — the vendoring was a 1.6.x stopgap, 1.7 is the first
version we land directly from hex.
oban_met (1.1.0) and oban_web (2.12.1) stay vendored — they're
not published to the licensed `oban` repo (verified by 404 on
`mix hex.package fetch`).
Migration 20260430142341 runs `Oban.Pro.Migration.up(version: "1.7.0")`
which creates the workflow tables and the new indexes. Verified on
dev + test DBs. Production is well below the size threshold the v1.7
guide flags for split-migration handling, so the inline default
suffices.
No code changes for the breaking-change list — the codebase only
references Oban.Pro.Engines.Smart and Oban.Pro.Plugins.DynamicLifeline,
both unchanged in 1.7. We don't use Workflow.after_cancelled/2 or
Oban.Pro.Workers.Chunk.
Test suite stays at 3132/3132.
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.
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.
Pre-existing CI failure (`tests/scorer_golden.rs`) — the Rust scorer
was still on the pre-recalibration weight vector, while the Elixir
side picked up new gradient-descent-fit weights in f98ee153.
- Update `DEFAULT_WEIGHTS` in band_config.rs to match the new Elixir
values (humidity 0.1262, time_of_day 0.0380, td_depression 0.1010,
refractivity 0.0986, sky 0.0841, season 0.1134, wind 0.0841,
rain 0.1431, pressure 0.0967, pwat 0.1147).
- Loosen the sum-to-one tolerance in `default_weights_sum_to_one`
from 1e-9 to 1e-3 to match Elixir's `assert_in_delta total, 1.0,
0.001` — gradient-descent fits land near 1.0 but not exact.
- Regenerate `tests/scores.bincode` from `mix rust.golden` so the
golden fixture reflects the recalibrated scorer outputs.
`cargo clippy --all-targets -- -D warnings` clean.
139 Rust unit tests + golden fixture pass.
3072 Elixir tests pass.
Retrained on 60k month-balanced HRRR profiles through 2026-04-05
(test RMSE 1.7 score points, R² 0.97). Added explain_prediction/4
returning ranked feature contributions via batched finite-difference
attribution, so the UI can show users which weather factors drove
each prediction.
New globally-shared list of rover-friendly (or off-limits) parking
spots. Anyone can view; logged-in users can add new locations and
edit/delete their own. Each location stores lat/lon, free-text notes,
and a status enum (:ideal | :off_limits).
* Microwaveprop.Rover.Location schema + migration
* Rover.list_locations/0, create_location/2, update_location/3,
delete_location/2 (mutations require User; ownership-scoped)
* /rover-locations LiveView in the public live_session — Add button
is disabled for anonymous visitors, Edit/Delete buttons render
only on the user's own entries
* Tests for context + LiveView covering anonymous read, owner-only
edit/delete, and form submission
Two issues spotted in pg_stat_user_tables:
1. Most `hrrr_profiles` partitions have `last_autoanalyze IS NULL`.
The partitions are append-only from the hourly grid worker, so
autovacuum never crosses the analyze threshold — but without
stats the planner falls back to estimates and picks bad joins
on per-QSO lookups.
2. `contacts`, `grid_tasks`, `hrrr_fetch_tasks`, and
`contact_common_volume_radar` see high UPDATE volumes
(enrichment status flips, queue claim/complete cycles, mechanism
classifier writes) but only accrue ~5% dead before the default
20% / 10% autovacuum triggers fire. BackfillEnqueueWorker's
status-priority ORDER BY + the Rust workers' FOR UPDATE SKIP
LOCKED claim scan both want fresher stats than that.
Changes:
- Migration `20260424204656_tune_autovacuum_for_high_churn` sets
per-table `autovacuum_*_scale_factor` + `_threshold = 50` on the
four tables above. Aggressive enough to keep stats current;
tame enough that vacuum doesn't thrash the Turing Pi 2 Postgres
node. Reversible.
- `Weather.analyze_all/1` walks `pg_stat_user_tables`, runs
`ANALYZE` on every table not auto-analyzed in the last 6 h,
reports counts. Meant to be invoked once via
`bin/microwaveprop rpc 'Microwaveprop.Weather.analyze_all()'`
after deploy to seed statistics on the cold partitions;
idempotent on re-run.
No translations are actually maintained and no UI is shipped in a
non-English locale. Replaced the handful of gettext(...) calls in
core_components + layouts with their literal English strings, and
rewrote translate_error/1 as a small %{key} interpolator over the
Ecto changeset error tuple.
Removes gettext + expo (compile dep). sutra_ui stays — it's a
transitive dep of live_table's TableComponent.
Replaces the SVG schematic on /eme with a textured WebGL scene: NASA
Blue Marble Earth, real-size Moon, outbound beam, dashed return ray
to the sub-lunar point, and a red shading on the anti-moon hemisphere
that marks who can't see the Moon (outside the bounce footprint).
Three.js (~680 kB) now lives in its own chunk; esbuild --splitting
keeps it out of the main bundle so it only loads when a user hits
/eme. Main app.js drops from 1.6 MB to 922 kB.
Also swaps the Elevation/SNR rows so the badge comes before the number.
Operators want a place to jot observations that aren't captured by
the structured fields — weather anecdotes, propagation mode
commentary, equipment details, band conditions. Add a text column
on contacts plus the two ingest paths users submit through:
* /submit single-contact form gets a 3-row textarea under the
other fields. Optional, max 2000 chars, with a live length cap
via maxlength. Whitespace-only input collapses to NULL so the
column reflects "no notes" rather than an empty string.
* CSV importer recognises a `notes` (or `note`) column via the
existing header_aliases table and flows values straight through
submission_changeset. Sample template gets a matching example
row with embedded commas so the quoted-field round-trip is
exercised on download.
ADIF import and the refinement/refinement-notify paths are out of
scope — users specifically asked for CSV + single-contact. Tests
cover the changeset (accept/blank/over-length), CSV header parsing
(plain + RFC-4180 quoted), and LiveView form submit end-to-end.
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.
Weather.find_nearest_hrrr/3 and Weather.find_nearest_native_profile/3
run a three-range scan gated first by a ±1h valid_time window, then
by a ±0.07° lat/lon box. The existing unique `(lat, lon, valid_time)`
index is only usable on its `lat` prefix for these queries, forcing
Postgres to scan wide lat slices before applying the valid_time
filter — expensive on the Turing Pi 2 node.
Add a `(valid_time, lat, lon)` composite so valid_time leads,
collapsing the search to a narrow btree slice inside a single
partition before the lat/lon box filter kicks in.
`hrrr_profiles` is RANGE-partitioned by valid_time, so
CREATE INDEX CONCURRENTLY is applied per partition and the resulting
indexes are attached to a parent index created ON ONLY the partitioned
table. `hrrr_native_profiles` is a regular table, so the concurrent
build runs directly on it.
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.

PropagationPrune ScoresFile), 0 regressions.
Column name now matches the type key used everywhere else:
:hrrr -> hrrr_status, :weather -> weather_status,
:terrain -> terrain_status, :mechanism -> mechanism_status
Drops the @status_column_overrides remap in BackfillEnqueueWorker
(status_column/1 is now a straight :"#{type}_status" derivation) and
the long-form references in Contact, ContactWeatherEnqueueWorker,
and MechanismClassifyWorker. Migration is a metadata-only RENAME
COLUMN + RENAME INDEX — safe to land in prod (no table rewrite,
brief catalog lock only).
Phase 3 Stream C Elixir-side: HrrrFetchWorker is deleted; per-QSO HRRR
enrichment now writes to the new hrrr_fetch_tasks table for the Rust
hrrr-point-worker to drain.
Table shape:
- one row per valid_time (primary key) with a JSONB array of
{lat, lon} points
- UPSERT on conflict: array-union of points, status flips back to
queued if previously done/failed so a backfill re-scan naturally
refills the queue for Rust
Elixir changes:
- new migration 20260419231502_create_hrrr_fetch_tasks
- new Microwaveprop.Weather.HrrrPointEnqueuer with enqueue/1 and
enqueue_for_contacts/1. Pre-2014 contacts (NARR's territory)
are skipped here so hrrr_status can pin them to :unavailable.
- ContactWeatherEnqueueWorker: build_hrrr_jobs/1 removed; single-
contact path and batch perform/1 both route through
HrrrPointEnqueuer.enqueue_for_contacts/1. A placeholder jobs-list
is kept just to feed mark_hrrr_status!.
- contact_live/show.ex retry button enqueues via the same path.
- :hrrr queue removed from dev/config/runtime.exs
- HrrrFetchWorker module + test deleted
BackfillEnqueueWorker scans continue to flow through
ContactWeatherEnqueueWorker.enqueue_for_contact (unchanged), so the
30-min reconcile refills hrrr_fetch_tasks automatically.
4 new tests cover the routing, pre-2014 skip, UPSERT-union, and
status-reset-on-reschedule behaviour. Rust-side hrrr-point-worker
binary + k8s deployment land in the next commits.
Prep for Stream A of Phase 3 rust migration: f00's native-duct merge,
NEXRAD, and commercial-link enrichment move to Rust via the same
grid_tasks work queue. kind='analysis' (single row per run) vs
kind='forecast' (18 rows per run) lets one Rust worker dispatch on
payload type without a second table.
Forecast default keeps existing Rust claim_next behaviour unchanged
during cutover.
Extracts the memory-hostile HRRR fetch → decode → score pipeline for
forecast hours 1–18 into a separate Rust service (`prop-grid-rs`).
Elixir retains f00 with its native-duct + NEXRAD + commercial-link
enrichment; Rust handles the other 18 steps per hourly chain.
Hand-off via a new `grid_tasks` table (`FOR UPDATE SKIP LOCKED` claim
from Rust, Postgrex `NOTIFY propagation_ready` back to Elixir). Rust
writes the same on-disk score-grid format Elixir already uses, to the
same `/data/scores` NFS tree. Phase 1 ships in shadow mode with
PROP_SCORES_DIR=/data/scores_shadow.
Rust crate layout at `rust/prop_grid_rs/` (1:1 module parity with the
Elixir source it ports):
- grid, region, band_config, scores_file, sounding_params
- scorer: all 10 factors + composite. Matches the Elixir scorer
byte-for-byte across 115 golden-fixture samples (5 scenarios
× 23 bands).
- decoder: wgrib2 subprocess + Fortran-record lola-binary parser
- fetcher: HRRR URL derivation + idx cache (1h TTL) + 8-way
parallel byte-range downloads with 429/5xx retry
- pipeline: end-to-end chain step, f00 rejected at the boundary
- db: sqlx grid_tasks claim/complete + propagation_ready NOTIFY
- bin/worker: tokio main loop, JSON logs, SIGTERM-safe
91 Rust tests + clippy -D warnings clean. 2,158 Elixir tests green.
Elixir additions:
- `GridTaskEnqueuer` seeds fh=1..18 rows from
`PropagationGridWorker.seed_chain/0`
- `NotifyListener` LISTEN → warm `ScoreCache` → PubSub fan-out
- `ShadowComparator` diffs prod vs shadow `.ntms` bodies
- `mix rust.golden` task writes the Rust-side golden fixture
k8s: new `deployment-grid-rs.yaml` pinned to talos5 (32 GB NUC) via
`prop-grid-rs=primary` nodeSelector + `workload=grid-rs:NoSchedule`
toleration, 512 Mi limit, sharing the existing NFS `/data` mount.
The plan document is at `plans/vivid-hatching-quail.md` (local to my
workstation); phases 2 (cutover) and 3 (talos5 concurrency tuning)
follow after 72h of shadow-mode parity.
Contacts can be marked private at submit time (single form, CSV
import, ADIF import) and edit time. Private contacts are hidden
from the public map, the public /u/callsign profile, and the
browse table for anonymous and non-owning viewers. The original
submitter and admins see them inline on the browse table with a
"Yes" badge, and the detail page shows a lock icon. Non-authorized
viewers get a 404 on the detail page.
Add optional height1_ft/height2_ft to contact schema, submit form, and
edit form (direct + suggest-edit paths). Heights flow through to the
elevation-profile terrain analysis so clearance and diffraction are
computed from the actual antenna height instead of a 10-ft default.
Editing heights resets terrain_status and re-enqueues
TerrainProfileWorker so the stored path analysis picks up the new
geometry.
Also fix mark_likely_duct/3: the pattern was grabbing the element
instead of the index, so no duct ever got flagged as the likely
propagation path even when extract_ducts returned a valid layer.
Lays the groundwork for a Day 2-7 propagation outlook driven by NCEP
GEFS ensemble-mean output, picking up where HRRR's 18-hour horizon
leaves off.
- GefsClient: NOMADS URL builder, forecast-hour list (3h to +240,
6h to +384), ensemble-mean message inventory, and a Magnus
dewpoint derivation (pgrb2a publishes RH rather than Td)
- gefs_profiles table + GefsProfile schema mirroring hrrr_profiles
so the scorer can run over rows from either source
- Weather.upsert_gefs_profile/1 and upsert_gefs_profiles_batch/1
No worker or UI yet — those land in follow-up commits.
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.
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.
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.

OAuth/OIDC discovery, MCP server card.
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.
