Preserve the camera, map source and layer selection across engine sessions. Restore the previous engine if startup fails and retain local history navigation.
Keep fire normalization, LOD, anchors, cards and selection portable while the native renderer owns ground cells, sprites, input and scene disposal. Cancel superseded/removed settle timers and unregister the original sprite collection.
Preserve all ten native raster pairs exactly in dev and preview; record source/click/focus/lifecycle, legacy Metal and full regression evidence with strict comparator sensitivity checks.
process.exit(2) after a successful fetch trips a libuv assertion on Windows and turns the exit code into 127. The four gates set process.exitCode and return instead, and discard the unread reachability response so an early exit does not wait for the server to finish the body.
