- SharedPacketHandler.handle_packet_update: dispatch on filter-result,
and use maybe_enrich/2 dispatched on the enrich? boolean instead of
an inner `if`. lookup_device_info/1 is now a trio of function heads.
- Cluster.Topology.child_spec: build_spec/3 dispatches on
(cluster_enabled?, topologies) tuples — no more nested `if`.
- Cluster.PacketDistributor.distribute_packet: maybe_broadcast/2
dispatches on the leader-and-enabled check; the non-leader / disabled
paths return :ok explicitly instead of relying on an `if` expression's
implicit nil.
Adds tests for SharedPacketHandler (filter/enrich/match paths,
callsign_filter + callsign_and_weather_filter factories) and extends
Cluster.Topology tests to cover the nil-topology and opts-merge cases.
Coverage 66.41 → 66.81%.
Adds ~800 new tests (incl. 27 StreamData properties) across 22 modules
that previously had little or no coverage. Highlights:
- Pure utility modules (LogSanitizer, PacketFieldWhitelist,
PacketSanitizer, DeviceParser, CoordinateUtils, BoundsUtils,
ParamUtils, Convert, WeatherUnits) get thorough unit + property
coverage including UTF-8 truncation boundaries, antimeridian
longitude wrap, Haversine symmetry, and unit-conversion inverses.
- JSON view modules (CallsignJSON, ErrorJSON, ChangesetJSON) verified
for envelope shape and error templating.
- Plugs (HealthCheck, RateLimiter, ApiCSRF) exercised for happy-path
and halt paths.
- GenServer modules (RegexCache, CleanupScheduler, DeploymentNotifier)
tested without touching the supervised singleton where possible.
- Drops the orphaned map_live/map_helpers_test.exs whose module name
collided with the new live/shared/coordinate_utils_test.exs.
