- treat unparsable map altitude values as absent instead of failing the whole import with an uncaught TypeError/ValueError - import CLIENT_BASE nodes on the router side: current firmware rebroadcasts them like ROUTER_LATE - compare the trig-derived origin longitude with a tolerance in tests
A present origin block that is not a map or lacks a usable lat/lon pair now raises instead of silently dropping the origin and projecting terrain against a different origin than the author intended. Accept the latitude/longitude key spellings alongside lat/lon.
Concurrent runs sharing one cache directory wrote the same fixed temp filename and could atomically publish an interleaved, corrupt tile that then stayed cached. Download and unpack through process-unique temp names and clean up archives after unpacking.
Cache keys carried id(TERRAIN_GRID), so a reused object address after a Config-reusing parse could serve losses computed against an earlier grid. Key the cache on a monotonically increasing per-grid token instead. Also pick the nearest interpolation samples with heapq.nsmallest instead of sorting every sample in this hot path, and use the shared node_antenna_height helper from lib.common instead of a diverging local copy.
Automatic SRTM tile selection evaluated the full link budget for every node pair. Derive one conservative best-case link distance (path loss grows monotonically with distance in every lib.phy model) and skip pairs beyond it before the expensive per-pair work; document that the selection scales with node pairs and recommend --map-limit for broad imports. Also log when a wrapped --map-bbox is discarded for terrain so the substituted extent is not silent, and import node_antenna_height from its canonical module.
TCPInterface connects without a socket timeout, so a stale --nodedb-host blocked the CLI indefinitely. Probe reachability with a bounded connect first so unreachable hosts fail fast with the existing could-not-connect error.
