- Detail panel now reads as an aiming card: "Aim 220° (SW) · clearance +12 ft"
with the precise bearing in degrees, plus rover/obstacle elev on a second line
- Elevation profile labels swapped from min/max-of-profile to start (rover) and
end (station) elevations, since their positions in the chart now match
- Map draws a dashed indigo polyline from the candidate to each selected
station when a candidate is opened; cleared when the panel closes
Calculate occasionally hung in production for ~30s. Adds per-phase
timing logs to Compute.run so the slow step is visible in pod logs,
and trims the Overpass road-proximity request to a 10s server-side
timeout / 12s receive timeout (no Req retries) so a slow road API
fails soft to no road penalty instead of stalling Calculate.
- Local prominence: each cell's elevation vs. its 8-neighbor ring
(~1.3 km radius) feeds a small additive bonus so broad hilltops
rank above isolated SRTM voxels
- Road proximity: one Overpass call per Calculate fetches drivable
ways inside the bbox; cells beyond ~0.5 km of any road get a
light dB penalty, gated off in tests
For each (rover cell, fixed station) pair, sample SRTM along the
great-circle path and add a per-link dB bonus proportional to the
rover's elevation above the highest intermediate terrain. Rover spots
on hilltops with clear sight to multiple stations now rise to the top.
Also vendor Leaflet's layers control PNGs and copy them under
priv/static/assets/css/images/ on build so /rover stops 404'ing on
layers-2x.png.
The /path calculator showed "0 / 9 HRRR points" in production despite
the on-disk profile store being current. Root cause: profile_from_cell/2
treated the cell's :profile key as a wrapper sub-map and called
Map.put_new on it — but the :profile key actually holds the vertical
pressure-level LIST. Every point sample crashed with BadMapError, the
crash propagated as {:exit, _} through Task.async_stream, and the
consumer silently dropped all 9 results.
Fix: stop wrapping. Cells are already flat HrrrProfile-shaped maps;
just stamp lat/lon (from the caller, since cells don't carry their
own coords — those are the map key) and valid_time onto the cell.
Audit + log every other async error path so the next silent failure
isn't invisible:
- PathLive HRRR point lookup
- Propagation.point_forecast per-hour reads
- Viewshed ray crashes
- IemClient ASOS network fetches
- RtmaClient range-download tasks
- Recalibrator factor-vector batches (positive + negative samples)
- MapLive forecast preload tasks
- RoverLive station resolution
LiveViews already had handle_async/3 exit clauses with logging. The
gap was always in Task.async_stream consumers that wrote {:exit, _} -> []
without surfacing the reason.
Add the rule to CLAUDE.md and project memory so this never repeats.
Also fix a pre-existing skewt_svg.ex compiler warning where
@critical_label_min_dy was used before being defined.
LCL/LFC and 0 °C/WBZ landed within ~5 px of each other on the right-
edge label rail and stomped on each other's text. Sort by y, bump
each subsequent label down by at least 14 px from the previous one,
and draw a thin leader from the true tick to the bumped baseline so
nothing reads as misaligned.
Also widened the SVG from 720 → 820 user units so longer entries
like `LCL 925 mb` no longer get clipped by the right edge.
The 18-hour forecast chart on /path now shows the same weighted-
criteria panel the /map popup builds when the user clicks a grid
cell. Hovering a dot fires a server roundtrip that fetches
Propagation.point_detail at the path's midpoint for that valid_time;
results are cached client-side so re-hovering is instant.
`Propagation.point_detail/4` now returns a `:profile_source` tag —
`:exact`, `{:fallback, fallback_valid_time}`, or `:unavailable` —
distinguishing real per-hour breakdowns (Rust pipeline writes a
profile file for every f00..f18 step) from rare cycle-miss fallbacks
where we approximate from a recent analysis profile. Stale comment
about "only f00 persists profiles" updated.
Map utilities (FACTOR_META, FACTOR_ORDER, factorBar,
factorExplanation, scoreTier, FactorMeta, ScoreTier) are now exported
from propagation_map_hook so the new path hook reuses the exact same
look + copy.
