Target and candidate both occupy 736 padded bytes, contain 247 instructions, and carry the same 35 ordered relocation identities; objdiff reports 99.99187 percent similarity. The only instruction-byte difference is the interchangeable load side of one commutative multiplication in the inlined camera-left dot product. The source retains typed player, unit, object, tag, observer, sound, rumble, and math access; uses the authenticated bit-8 damage-indicator enum name; and keeps owner prototypes in player_effects.h and random_math.h. A shared owner-header enum insertion was rejected because a full rebuild reopened the protected units.obj node-orientation sentinel; the named constant is therefore TU-private. No raw offset, false type or prototype, representation pun, volatile/register forcing, barrier, pragma, assembly, fake dependency, forced inline, undefined behavior, or nonsensical branch is retained. Reopen only for authoritative January source/local records or natural same-compiler evidence for the final commutative operand order.",
