Three connected changes:
1) Extract PathLive.compute_path/4 + every helper it owned (resolve,
profile grid lookup, sounding/ionosphere readouts, scoring, loss /
power budgets) into Microwaveprop.Propagation.PathCompute. PathLive
now delegates; ~410 lines of dead helpers deleted from PathLive.
2) RoverPathProfileWorker calls PathCompute.compute/4 with the
mission's heights and PathLive's default station params (10 W TX,
30 dBi gains). Stores the full atom-keyed compute output as a
Base64-encoded :erlang.term_to_binary/1 blob alongside the flat
summary fields the rover-planning show table reads. The blob
roundtrips structs and DateTime exactly (Jason.encode would lose
them).
3) PathLive accepts ?rover_path_id=UUID. When set, loads the cached
Path, decodes the term (binary_to_term :safe), assigns it as
@result, and renders normally — no compute_path call. The
rover-planning show table now links rows directly to
/path?rover_path_id=UUID, so a click opens the full Path
Calculator UI from cached data without re-running terrain / HRRR /
sounding lookups.
Bonus prod fixes folded in:
- PathShow's elevation chart attribute (data-* → data-profile JSON)
was crashing the JS hook with 'unexpected character at line 1'.
- Station.changeset now wipes previously-resolved callsign/grid/
lat/lon when the user types into :input — typing 'AA5' early
resolved to a wrong location and locked it; subsequent keystrokes
never re-resolved.
- phx-debounce=600 on the station input so QRZ doesn't get hit on
every keystroke.
Worker now stores the full per-point analysis (beam height,
Fresnel-zone radius, clearance) on Path.result.path_points, and
PathShow renders a real cached page: terrain elevation chart fed by
the same ElevationProfile JS hook /path uses (feet on Y, miles on X,
LOS + Fresnel overlay), distance / bearing / clearance / antenna
heights all in feet, baseline link-budget breakdown, and the cached
midpoint propagation score with computed_at timestamp.
A Recompute live button hands off to /path for the time-varying bits
(current HRRR conditions, scoring breakdown, sounding, ionosphere)
that aren't worth caching.
The cached path-detail URL was a thinned-down view (geometry +
loss-budget summary + score). The user wanted the same rich display
/path renders — terrain chart with feet axes + tooltips, conditions,
scoring, link/power budgets, forecast — so PathShow now resolves the
row's rover/station/band/heights and push_navigates to /path with
those params baked in. The cached result map on Path.result is still
what the rover-planning show table reads from for fast row rendering;
this just bridges the row click to the canonical Path Calculator.
New /rover-planning/:id/paths/:path_id route renders the worker-stored
result map directly: geometry, link-budget components, propagation
score, computed_at. The 'Recompute live' button hands off to /path
when the operator wants HRRR-driven loss against current weather.
