In general I like the idea. However, is it correct this currently only works for one specific map?

and atomically publish only the completed tile.
In `@lib/terrain.py`:
- Around line 82-98: Update elevation_at to use heapq.nsmallest when selecting
the nearest eight samples instead of sorting all samples, preserving the
existing distance ordering and interpolation behavior. If implementing the
larger-grid optimization, add a uniform bucket index keyed by rounded (x, y)

- Around line 186-215: Update the terrain loss cache initialization and lookup
flow to track the active TERRAIN_GRID with a persistent version or identity
token, rather than relying only on id(conf.TERRAIN_GRID) in cache_key. When
parse_params replaces the grid on a reused Config, detect the token change,
clear _terrain_loss_cache, and update the active token before serving cached
losses; preserve normal LRU behavior for an unchanged grid.
In `@loraMesh.py`:
- Around line 460-465: When terrain_srtm is enabled and
bbox_crosses_antimeridian(terrain_bbox) causes terrain_bbox to be cleared, log
that the wrapped map bounding box is being discarded and terrain extent will be

corresponding three branches, while preserving the existing node-filtering and
terrain_bbox = None behavior.
- Around line 223-232: The node-pair loop in loraMesh.py lines 223-232 should
prefilter pairs using the configured maximum-range distance before calling
nodes_have_flat_link_budget, thereby skipping estimate_path_loss,
bboxes_from_points, and tiles_for_bbox for distant nodes. Update
DISCRETE_EVENT_SIM.md lines 63-67 to state that tile selection scales with
node-pair count and recommend --map-limit when combining --terrain-srtm with a
broad map import.
Apply the same fix in `@DISCRETE_EVENT_SIM.md` around lines 63 - 67: Document the
node-pair scaling and recommend --map-limit.
In `@tests/test_lora_mesh_cli.py`:
- Line 254: Split the tuple assertions so latitude remains an exact comparison
while trig-derived longitude uses assertAlmostEqual. Apply this at

and at tests/test_map_input.py lines 231-234 for origin[1] against 41.59; keep
the latitude comparisons exact.
- Around line 692-694: Update the YAML origin fixture in this scenario to use
the schema keys lat and lon instead of latitude and longitude, so
origin_from_yaml produces a parsed origin and the test specifically verifies
that it is discarded when the node-count check fails.

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
node_antenna_height is copy-pasted across modules and the copies already differ. The shared root cause is that each module defines its own helper instead of importing one definition. The lib/common.py copy reads antennaHeight before antenna_height; the lib/terrain.py copy reads them in the opposite order. Both resolve to the same value for NodeConfig and MeshNode today, so this is not a live defect, but a future node type that carries only one of the two attributes would behave differently depending on which copy runs. loraMesh.py holds a fourth copy with the same problem.
lib/common.py#L9-L11: keep this as the single definition and fix the lookup order to match the terrain semantics you want.lib/common.pyhas no terrain dependency, so it stays import-cycle free.lib/terrain.py#L131-L137: delete the local definition and import the helper fromlib.common.lib/packet.py#L4-L7: keep thefrom lib.common import node_antenna_heightimport at line 4 and delete the shadowing local definition reported at lines 9-11.
Apply the same deletion to the loraMesh.py copy so all call sites resolve one definition.

sole shared definition, with lookup order matching the desired terrain
semantics. In lib/common.py lines 9-11, update the canonical helper; in
lib/terrain.py lines 131-137 and lib/packet.py lines 4-7, remove local shadowing
definitions while preserving the existing lib.common import in packet.py. Remove
the duplicate helper from loraMesh.py as well so all call sites resolve the
shared implementation.

The origin keys in this scenario do not match the YAML schema.
origin_from_yaml reads the keys lat and lon. Other tests in this file use those names at Lines 774-775 and Lines 877-878. This scenario uses latitude and longitude, so origin_from_yaml returns None.
The test still passes, but it passes for the wrong reason. It proves that a scenario with no recognized origin is rejected. It does not prove that a parsed origin is discarded when the node count check fails.
💚 Proposed fix
origin:
- latitude: 42.0
- longitude: 42.0
+ lat: 42.0
+ lon: 42.0

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@tests/test_lora_mesh_cli.py` around lines 692 - 694, Update the YAML origin
fixture in this scenario to use the schema keys lat and lon instead of latitude
and longitude, so origin_from_yaml produces a parsed origin and the test
specifically verifies that it is discarded when the node-count check fails.
- 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.
