174-186: Symmetry in the Force, I feel. Backward propagation mirrors forward, it does.Similar changes in backward propagation, maintain balance they do. But careful with memory access patterns, we must be.
Consider this improvement, you should:
- for (auto it = begin; it != end; ++it) { - propOptions.navigation.insertExternalSurface( - options.extensions.surfaceAccessor(SourceLink{*it})->geometryId()); - } + // Cache surface IDs from forward pass, we could + std::vector<GeometryIdentifier> surfaceIds; + surfaceIds.reserve(std::distance(begin, end)); + for (auto it = begin; it != end; ++it) { + surfaceIds.push_back( + options.extensions.surfaceAccessor(SourceLink{*it})->geometryId()); + } + for (const auto& id : surfaceIds) { + propOptions.navigation.insertExternalSurface(id); + }

153-186: Architecture wisdom, share I must.External surfaces in navigation, reduce holes they may. But measure their impact, we should.
Consider these architectural improvements:
- Add telemetry to track number of holes before and after external surfaces
- Consider caching mechanism for frequently accessed surfaces
- Implement fallback strategy when surface access fails

Line range hint 153-166: Hmmmm, wise changes in forward propagation, I sense.
Capture by reference and external surfaces insertion, good practices these are. But verify the surface accessor's behavior, we must.
✅ Verification successful
Safe and proper, the surface accessor usage is, young padawan.
Through the Force, I sense that:
- A default void implementation exists that throws if accidentally used, preventing silent failures it does
- In production code, proper implementations connected they are, before any usage occurs
- The geometryId() access protected it is, by the non-null surface pointer the accessor provides
- In test code, proper surface accessors with geometry backing them, implemented they are
No danger in the changes I sense. The path of the code, clear and safe it is.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for surfaceAccessor implementations to verify null checks
ast-grep --pattern 'surfaceAccessor($_) {
$$$
}'
# Check for potential null surface returns
rg -A 5 'surfaceAccessor'
Length of output: 30501
Script:
#!/bin/bash
# Search for surfaceAccessor implementations and null checks
ast-grep --pattern 'const Surface* $_ = $$.surfaceAccessor($_);
if ($_ == nullptr) {
$$$
}'
# Search for voidSurfaceAccessor implementation
rg -A 5 'voidSurfaceAccessor'
Length of output: 2225

Try external surfaces for standard navigation in GSF. Might reduce number of holes?
