Wires PromEx with its built-in Application / BEAM / Phoenix / Ecto /
Oban plugins plus a custom `Microwaveprop.PromEx.InstrumentPlugin`
that registers Prometheus histograms for every
`Microwaveprop.Instrument` span (HRRR/NEXRAD/IEM/GEFS/NARR/UWYO
/Elevation fetches, DB batch upserts, terrain analysis, radar
aggregation, propagation score band). Queue-depth gauges from the
10-second poller land at `microwaveprop_oban_queue_count{queue,state}`.
Router forwards `/metrics` to MicrowavepropWeb.MetricsPlug which
optionally requires a bearer token (`PROMETHEUS_AUTH_TOKEN` env var in
runtime.exs); leave it unset to expose metrics publicly and restrict
at the ingress / Cloudflare Access layer instead.

- job_name: microwaveprop
scrape_interval: 30s
metrics_path: /metrics

Since da6b312 (Add live_table dep), every main-branch CI build has
silently failed on `mix deps.compile` inside the Docker builder. The
failure is that live_table ships two unguarded mix tasks —
lib/mix/tasks/live_table.install.ex and
lib/mix/tasks/live_table.gen.live.ex — both of which do
`use Igniter.Mix.Task` at the top level without wrapping it in a
`Code.ensure_loaded?(Igniter.Mix.Task)` check. When Igniter isn't
available, compiling the live_table dep blows up with
`module Igniter.Mix.Task is not loaded`.
I had declared igniter as `only: [:dev, :test], runtime: false`
which meant it was only fetched in those envs, so the prod Docker
build never had it and failed there. The blast radius is every
commit from da6b312 through 263c1bb (14 commits) none of which ever
made it to prod:
- /users, /beacons, /contacts, /admin/contact-edits live_table
conversions
- Admin nav dropdown
- Cap "Contacts I'm in" at 100
- Contact detail path-calc link + 10 ft AGL assumption
- Path calculator callsign tooltip
- Drop gridmap.org and do QRZ + Google geocoding locally
- Feed Loss (×) HEEx escape fix
- Path forecast line chart and refractivity gradient unit fix
- Float.round/2 crash fix on clear-terrain diffraction loss
Drop the env restriction on igniter so it's available to the prod
build as well. `runtime: false` keeps it out of the release bundle
so there's no runtime bloat, it's strictly a compile-time build
tool for the live_table dep.
Verified locally with a clean `_build/prod` + `MIX_ENV=prod mix
deps.compile` (all 54 deps including live_table now build) and the
full test suite still passes.
Instead of shelling out to https://gridmap.org/locate/:callsign for
callsign → lat/lon lookups, ports the resolver pipeline from gridmap-web
into this project so the whole flow runs in-process.
New modules:
- Microwaveprop.Qrz — cache facade over the QRZ.com XML callsign API.
Looks up from qrz_callsigns first, falls back to a live fetch, and
upserts the result with a configurable cache_ttl_hours (default
168h / 7 days).
- Microwaveprop.Qrz.Client — HTTP/XML client against
https://xmldata.qrz.com/xml/current/. Holds the session key in an
Agent, transparently re-logs-in on :session_expired, and parses
responses via xmerl.
- Microwaveprop.Qrz.Callsign — Ecto schema for the qrz_callsigns
cache table, binary_id primary key per project convention.
- Microwaveprop.Qrz.Record — slim struct with only the 11 fields
we actually consume (identity, name, grid, address, lat/lon).
The full XML payload stays in the raw :data jsonb column for
anyone who wants the other ~40 QRZ fields.
- Microwaveprop.Geocoder — Req-based client against the Google Maps
Geocoding API. Only called as a fallback when QRZ has no explicit
<lat>/<lon> for the callsign.
- Microwaveprop.CallsignLocation — orchestrator. Reads the
callsign_locations cache, on miss calls Qrz then either uses QRZ's
coords directly or geocodes the formatted address, snaps to an
8-char Maidenhead grid via Microwaveprop.Radio.Maidenhead, and
upserts the result.
Microwaveprop.Radio.CallsignClient.locate/1 is rewritten to delegate
to CallsignLocation.lookup/1 and shape the response back to the
existing {:ok, %{callsign, gridsquare, lat, lon}} contract so the
callers in PathLive and RoverLive don't change.
Wiring:
- priv/repo/migrations/20260413000000_create_qrz_callsigns_and_callsign_locations.exs
creates qrz_callsigns and callsign_locations with unique indexes
on :callsign.
- Microwaveprop.Qrz.Client added to the application supervision tree
so the session Agent is started.
- :xmerl added to extra_applications so the release bundles it.
- config/test.exs wires Req.Test plugs for Microwaveprop.Qrz.Client
and Microwaveprop.Geocoder, forces cache_ttl_hours: 0 so the cache
never short-circuits test-level stubs, and supplies dummy QRZ
credentials.
- config/runtime.exs pulls QRZ_USERNAME / QRZ_PASSWORD / QRZ_AGENT
and GOOGLE_API_KEY from the environment so prod and dev can
configure both upstream keys out of band.
Tests (ported verbatim from gridmap-web):
- test/microwaveprop/qrz/callsign_test.exs — schema/changeset
- test/microwaveprop/qrz_test.exs — cache hit, cache miss, TTL
behavior, upsert on stale, error passthrough, case-insensitive
input
- test/microwaveprop/geocoder_test.exs — success, zero results,
request denied, transport error
- test/microwaveprop/callsign_location_test.exs — end-to-end flow
including the QRZ-lat/lon shortcut and the missing-address error
path
All 1294 tests still pass. Credo strict clean.
Wire up gurujada/live_table 0.4.1 as a dependency (alongside its
transitive sutra_ui and optional igniter requirement) with the
:live_table config pointing at our Repo and PubSub. Forced oban_web
override so the path-pinned vendored copy still wins over live_table's
hex constraint.
Convert the admin /users page to use LiveTable.LiveResource with
sortable, searchable columns for callsign, name, and email. Custom
renderers preserve the daisyUI admin badge and the pending/confirmed
date cell. Hidden id field stays in the query so the edit and delete
actions can target a record by id.
Updated the delete test to push the delete event directly with an id
payload; the stream dom_ids under live_table are random UUIDs so
tr#users-<id> selectors no longer work.
Adds the commercial Oban Pro package (vendored from the towerops-web2
vendor tree) so this project can use its workers, plugins, and
Smart engine features.
Vendor oban_web 2.12.1 and oban_met 1.1.0 (taken from the
towerops-web2 vendor tree), bump oban to ~> 2.21, and mount the Oban
dashboard at /admin/oban behind the existing require_admin on_mount
hook. Adds an admin-only "Oban" nav link and extends the Dockerfile
to copy vendor/ before deps.get so production builds pick up the
path dependencies.
Users can now register beacon monitors on the settings page. Each
monitor gets a unique random token the remote program will use to
authenticate its reports. Name is the only user-supplied field for
now; more will be added as the monitor protocol is defined.
Also adds :gen_smtp to deps. Swoosh's SMTP adapter depends on
:mimemail which lives in that package, and production was 500'ing
when trying to send confirmation emails without it.
Generated Accounts context, User schema, and controllers via
phx.gen.auth. Adapted it for password-only login with required
email confirmation:
- Users have callsign (unique, uppercased), name, email, password
- Registration form fields: callsign, name, email, password, confirm
- Magic-link login path removed; login is email + password only
- After register, a confirmation email is sent and login is blocked
until the account is confirmed via the token URL
- Confirmation link logs the user in on first use
- SMTP2GO configured as the outgoing mailer in k8s prod
- Add ecto_psql_extras for PostgreSQL insights in dashboard
- Add os_mon for OS metrics (CPU, memory, disk)
- Fix progress bars using percentage instead of raw large numbers
- libcluster with Kubernetes IP strategy for pod discovery
- RBAC for pod list/get, POD_IP from downward API, shared cookie
- LiveDashboard at /dashboard for all environments
- Add timex ~> 3.7, downgrade gettext to ~> 0.26 for compatibility
- Parse ISO 8601, US dates (M/D/YYYY), AM/PM, 24h, compact formats
- 22 tests covering all accepted timestamp formats and edge cases
- Integration tests for CSV import with US date and space-separated formats
- Nx, Axon, EXLA, Polaris deps restricted to only: [:dev, :test]
- model.ex and training mix tasks moved to lib_ml/ (compiled via
elixirc_paths in dev/test only)
- load_ml_model uses Code.ensure_loaded? + apply/3 to avoid
compile-time references to ML modules in production
- Verified: MIX_ENV=prod compiles clean with no ML warnings
- Add polaris dep for Adam optimizer (Axon.Optimizers deprecated)
- Fix Model.train/3 to use Polaris.Optimizers.adam
- Training task: mix propagation_train with stratified band sampling
- Model encodes solar time (longitude/15) not fixed timezone
