Save Selector Active Flag Sources

route: map1_01a -> map2_02d; active flag 0x00457744; static byte 0x01; save offset 0x006c.

startup init 0x00411300; calls 1; exact refs 4 (reads 3, writes 1); resolved static default: True; promotion status blocked.

The opcode 0x12 active-selection flag is not an unknown static producer: the executable image initializes 0x00457744 to 1, and startup routine 0x00411300 writes it to 1 via a direct byte store called from 0x00401928. The same byte is also inside the first save-read block at save offset 0x006c, so a loaded save can override the startup/default value. For the current blocker this removes the static-writer mystery around byte(0x00457744), but route promotion is still blocked because the actual runtime/save value, prior selectionBuffer[0x20], secondaryBranchState contents, control path, and strict map1_01a hotspot remain unproven.
