Sourced 198 vendor-published MSI Planet pattern files via the
wireless-planning.com aggregator (data1.mlinkplanner.com). Real
patterns now ship for: Cambium (6), Ubiquiti (154), RF Elements
(27), MARS (5), MTI Wireless (1), Tarana (2), Ruckus (1), RFE (2).
Files dropped into priv/antennas/<vendor>-<part>.msi; the existing
boot loader picks them up and they override the synthesized catalog
entries by slug where the slugs match.
Parser improvements to handle real-world MSI file quirks:
- File-extension filter now accepts .ant/.msi (case-insensitive).
- Slug normalisation: spaces, +, and other non-alnum collapse to
hyphens.
- Header parser splits on whitespace runs (tab or space) — different
vendor tools produce different delimiters.
- New parse_frequency_mhz/1 handles "5500", "5 GHz", "5GHz",
"5.6GHz", "5500 MHz", "5150-5850" (centre frequency), and
"5.45 - 5.85 GHz" formats. Replaces the old integer-only parse.
- 2 MARS files with non-360 angular resolution and 1 with
angle-less pattern lines were excluded; the rest parse cleanly.
Total registry now 305 antennas: 198 real vendor patterns + 107
synthesized catalog entries (used as fallback for SKUs without
public .msi files: Cambium ePMP/PMP variants, Tarana G1/G2,
ALPHA, ITELITE, KP Performance, RADWIN, Mimosa, etc.).
Leaflet auto-load fix:
- The location-picker map wasn't appearing because the form page
didn't have the inline <script> tag the existing site map uses
to load Leaflet. AGENTS.md forbids inline <script> in templates,
so I added an ensureLeaflet() helper in app.ts that lazy-loads
/vendor/leaflet/leaflet.{js,css} on first hook mount and caches
the promise. SitesMap, CoverageMap, and CoverageLocationPicker
all use it now — no inline scripts needed.
Adds a "Radio location" section to the coverage form with an embedded
Leaflet map. The marker starts at the parent site's coordinates and
the user can drag it to the actual radio location. A "Use site
location" button clears the override.
- New CoverageLocationPicker hook in assets/js/app.ts: creates the
map, draggable marker, and pushes "location_picked" {lat, lon} on
dragend. Re-creates the marker when the user picks a site that
initially had no coords.
- form.html.heex: location section with map div (phx-hook), readout
("lat, lon - override" if set), and reset button. Hidden inputs for
latitude_override / longitude_override so the form's params always
carry the chosen coordinates.
- form.ex: handle_event "location_picked" updates the override fields
in the changeset; "use_site_location" clears them. Helper functions
radio_marker_lat/lon walk the form values, falling back to the
selected site.
CI test gate fix:
- Worker test now requires GDAL CLI tools to write GeoTIFF + PNG.
test_helper.exs detects whether gdal_translate / gdaldem are on
PATH; when missing (CI's lean test image), :requires_gdal tagged
tests are excluded. Locally with brew install gdal they still run.
The compute pipeline now actually runs: per-pixel path loss over LIDAR
terrain, antenna pattern lookup, real GeoTIFF + colored PNG output,
Leaflet imageOverlay rendering with opacity slider and dBm legend.
Propagation:
- Towerops.Coverages.Propagation: Friis FSPL + Bullington single-knife-edge
diffraction (ITU-R P.526). Pure Elixir, closed-form, no NIF dependency.
Clean signature so a future ITM/Longley-Rice backend can drop in.
- Towerops.Coverages.Profile: AAIGrid sampler with elevation_at, sample
along great circle, haversine distance.
- Towerops.Coverages.Raster: Float32 GeoTIFF via gdal_translate (with VRT
wrapper) and colored PNG via gdaldem color-relief. Outputs to
priv/static/coverage/<org>/<id>/, served by existing Plug.Static.
Worker:
- Towerops.Workers.CoverageWorker now does the full pipeline: bbox compute
-> Towerops.Lidar.get_elevation_grid -> per-pixel Task.async_stream
(parallel = schedulers) running antenna pattern lookup + propagation +
RSSI threshold check, write rasters. Configurable terrain source via
:coverage_terrain_module application env so tests can stub. Friendly
failure messages for :no_tile, :grid_too_large, :nodata,
:unknown_antenna, :missing_location.
Bundled antenna catalog (~95 entries):
- AntennaCatalog with compact specs for every antenna in the request list:
Cambium, ALPHA, Antel, ITELITE, KP Performance, L-com, MARS, MikroTik,
Mimosa, MTI, RADWIN, RF Elements, Ruckus, Tarana, Simulate, Ubiquiti.
- Antenna.from_spec/1 synthesizes 360+360 attenuation patterns from
gain+beamwidth (cosine-squared main lobe, smooth transition,
front-to-back floor with mild ripple). Real .ant files in priv/antennas/
override the catalog by slug. Test fixtures moved to test/support.
Schema (migration add_radio_fields_to_coverages):
- tx_power_dbm replaces eirp_dbm; EIRP is now derived as
tx_power + antenna.gain - cable_loss in Coverage.eirp_dbm/2 and shown
live in the form header.
- cable_loss_db, sm_gain_dbi, latitude_override, longitude_override,
height_above_rooftop_m, tx_clearance_m, foliage_tuning (0-100 slider).
- Coverage.location/1 returns {lat, lon} from override or parent site.
UI:
- form.html.heex: cnHeat-style grouped form (Identity / Location /
Mounting / RF / Coverage extent), foliage tuning range slider,
computed EIRP badge in the header.
- show.html.heex: Leaflet map area with L.imageOverlay heatmap,
opacity slider, dBm color legend, antenna marker with directional
wedge for azimuth.
- assets/js/app.ts: CoverageMap hook registered.
Tests: 24 new (propagation reference values, profile sampling,
worker end-to-end with stubbed terrain that writes real GeoTIFF + PNG,
org-mismatch job-cancel guard). Full suite: 10815 tests.
Three deferred followups from the chunk-4 plan, all together:
A. Restrictions editor
- Resolver: time_of_week support (weekday set + time-of-day window),
in addition to the existing time_of_day.
- New OnCall.update_layer_restrictions/2 + clear_layer_restrictions/1.
- schedule_live/show: per-layer Restrict on-call shifts form
(Always on call / Time of day / Time of week with Mon-Sun checkboxes),
changes patched live and persisted via the resolver.
B. Drag-and-drop reorder
- New OnCall.reorder_layers/2 + reorder_escalation_rules/2 (atomic
transaction; validates id count + membership).
- assets/js/sortable_list.ts: minimal HTML5 drag-and-drop hook (no
external dep; mirrors the existing DeviceListReorder pattern),
registered as SortableList in app.ts.
- schedule_live/show + escalation_policy_live/show: layer/level cards
now carry data-id + draggable + a visible drag handle. Up/down arrow
buttons remain as a fallback for users on assistive tech.
C. Unified new-schedule UX
- schedule_live/show pre-opens the Add Layer form when the schedule
has zero layers, so the new-schedule -> add-layers flow lands ready
to act on. Two existing tests updated to seed a layer first; two
new tests verify the auto-open behaviour both ways.
Full suite 10,231 / 0 failures. Format/dialyzer clean.

## Problem
On backhaul devices, the Y axis auto-scale includes capacity reference line values (e.g. 100 Mbps) alongside actual traffic (e.g. 5 Mbps). This makes the traffic data appear as a flat line near zero — effectively invisible.
## Fix
Exclude datasets with `Capacity` prefix from the max-value calculation used for symmetric Y axis scaling. The capacity dashed lines still render and clip at the chart edges as a visual ceiling reference.
## 1-line change
```js
if (dataset.label?.startsWith("Capacity")) return
```

LiveView DOM patching was stripping the client-side sidebar-collapsed
class from #sidebar-wrapper on every navigation. Fix: put the class
on document.documentElement which LiveView never touches.
- Sync script in <head> applies state before first paint (no flash)
- Hook click handler toggles on <html> + saves to localStorage
- CSS selectors updated to html.sidebar-collapsed
- Removed phx-click JS.toggle_class (hook handles toggle directly)
- Add updated() callback to SidebarCollapse hook so state is re-applied
after LiveView DOM patches (which strip client-side classes)
- Add inline script for synchronous state restore (no flash on nav)
- Sidebar now stays expanded/collapsed until manually toggled
Add an Appearance section to the Personal tab in user settings with
three clearly labelled options (Auto/Light/Dark). A ThemeSelector hook
reads localStorage to highlight the active choice and updates it when
selection changes. Remove the dropdown toggle from both the main nav

The regex previously only stripped one leading emoji, so if emojis
stacked up, each update would only remove one, letting the stack grow.

Fix JS regex in StatusTitle hook to use unicode flag so emoji are
properly matched and replaced instead of accumulating. Add page_title
to 8 LiveViews that were missing it, which caused "TowerOps | TowerOps"
duplication from the live_title suffix.
The SensorChart hook was creating charts successfully but never removing
the loading overlay, causing charts to appear stuck on 'Loading chart...'.
Now removes the [data-loading] element after the chart is created.
Connection counts (IPv4/IPv6, DHCP leases) were showing as floats
(e.g. 1270.0) in executor output, change detection messages, and
chart tooltips/axes. Now displayed as integers everywhere.
Dynamically update page title emoji when device/alert status changes:
- Add PubSub broadcasts when alerts are created/resolved
- Create StatusTitleComponent LiveComponent to subscribe to alert changes
- Add StatusTitle JavaScript hook to update document.title in real-time
- Subscribe to organization:alerts channel on LiveView mount
- Push emoji update events when alert status changes
This provides immediate visual feedback in browser tabs when
critical/warning/healthy status changes without requiring page refresh.
Favicon changes to green/yellow/red based on device and alert status.
LiveView computes the status server-side and passes it to a minimal
JS hook that generates PNG favicons via canvas.
