source/camera/orbiting_camera.obj exact-match record

Environment and scope

• Compiler: XDK 3911 CL.Exe 13.00.9254.1.
• Flags: /O2 /Oy- /DDEBUG /Dxbox.
• January target: pristine cachebeta.exe, regenerated with csplit.
• Complete object inventory: two functions, one 20-byte constants section, and one 40-byte owned path-string section.

The hardened comparator reports all_equal: true. The constants owner has COFF type 0 and storage class 3 on both the regenerated target and rebuilt object.

Closing source and ownership evidence

The prior external declaration made orbiting_camera_update differ only in a nine-byte scheduling window. The compiler delayed the two loads from rdata_0025724c until after the zero-vector and depth stores. Declaring the constants table static const gives VC7 translation-unit ownership and non-aliasing knowledge; it then emits the January load/store interleaving exactly, without changing source semantics or any other instruction.

This is also the evidence for the original linkage:

• no other translation unit references rdata_0025724c;
• the object owns the complete 20-byte table;
• static const alone reproduces every function byte and relocation address;
• config/symbols.json now marks the csplit symbol static, producing storage class 3 on both sides.

Rejected experiment and do-not-repeat list

• Expanding result->offset = *global_zero_vector3d into three scalar assignments regressed the update to 52 relocations and introduced repeated global loads. It was reverted.
• Five older assignment/declaration-order permutations failed to improve the external-linkage baseline and were reverted.
• Do not revisit barriers, volatile, assembly, undefined behavior, byte forcing, compiler pragmas, or flag changes. None is needed.

Disposition

Complete and strict-exact. The stale parked entry was removed and the object is marked Matching.
