rasterizer_transparent_geometry.obj Codex checkpoint

Scope and provenance

This is an honest partial checkpoint. source/rasterizer/rasterizer_transparent_geometry remains NonMatching; neither config/config.json nor the parked-function ledger is changed.

The reconstruction was recovered from the object-specific source history in claude/near-complete-objects-20260816, specifically commits 2d0b1956, f2b75a73, d57def09, and 6d5fe559. Only the C source was transplanted onto canonical a5f816f2. Claude-authored Markdown and the branch's unrelated history were not copied, edited, or deleted.

The imported source was then tightened before admission:

• the two emitted-but-nonexact definitions, rasterizer_transparent_geometry_initialize and rasterizer_transparent_geometry_next_group, were removed;
• struct vertex_buffer is read through its typed type member from rasterizer_geometry.h, not by reinterpreting the pointer as short *;
• the combined 0x4A-byte runtime state remains one packed object so its offsets and common-symbol size stay fixed, while source aliases preserve January's attested identifier spelling in assertion strings.

Strict result

The forced XDK 3911 build emits 13 code sections. Every emitted section is strict semantic-COFF exact: padded size, normalized bytes, relocation count, relocation types, symbolic destinations, and addends all agree.

Function	Padded bytes	Relocations
_rasterizer_transparent_geometry_begin	48	5
_rasterizer_transparent_geometry_end	16	0
_rasterizer_transparent_geometry_get_primary_vertex_type	112	7
_rasterizer_transparent_geometry_get_group_presorted_index	192	12
_rasterizer_transparent_geometry_get_group_from_presorted_index	80	6
_rasterizer_transparent_geometry_get_groups2	32	2
_rasterizer_transparent_geometry_get_groups	16	1
_rasterizer_transparent_geometry_new_group	48	3
_rasterizer_transparent_geometry_new_group2	48	3
_rasterizer_transparent_geometry_stop	16	1
_rasterizer_transparent_geometry_dispose	128	15
_rasterizer_transparent_geometry_set_group_pending_status	96	4
_rasterizer_transparent_geometry_get_group_pending_status	64	2

Total strict code is 13/19 functions, 896/2,304 padded bytes, 818/2,174 meaningful bytes, and 61 strict relocations. The a5f816f2 baseline had only begin and end, so this checkpoint adds 11 strict functions and 770 meaningful code bytes without losing either baseline-exact function.

The candidate retains the exact 74-byte common-BSS size and layout for _bss_004b8ad8. Its five emitted production string COMDATs are target-identical; the strings owned only by the six unimplemented target functions remain absent. The ordinary report therefore stays partial and does not claim whole-data or whole-object completion.

Remaining target functions

Six target functions remain deliberately absent:

• _rasterizer_transparent_geometry_initialize — 160 padded bytes / 16 relocs;
• _rasterizer_transparent_geometry_next_group — 160 / 12;
• _code_00173f70 — 48 bytes;
• _code_00173fa0 — 384 bytes;
• _code_00174120 — 176 bytes;
• _rasterizer_transparent_geometry_draw — 480 bytes.

The first two had readable implementations on the Claude branch but were not strict. initialize is an exact-size/relocation block-placement tie. next_group is an exact-size/relocation epilogue scheduling tie; the already measured result-variable, flat early-return, nested early-return, and pre-cast increment forms did not close it.

The final four are one interlocked cluster. The comparator uses still-unnamed fields at offsets 0x08, 0x70, and 0x9D; the sort driver references it and emits the private assert helper; draw calls the driver. They should be reopened only when source/PDB/oracle evidence supplies those field identities. Guessing names would contaminate four functions at once.

Gates

• forced clean XDK object rebuild: pass;
• hardened whole-emitted-function comparison: 13 exact, 0 emitted residuals;
• full Halo and libcmt build graphs: pass;
• semantic report: 470 units, 0 unit errors;
• object-admission audit: 0 candidates, 0 revocations; only the pre-existing unrelated shell_xbox contradiction remains;
• config remains NonMatching;
• house/Berth scan: no asm, volatile, forceinline, optimizer pragma, barrier, byte forcing, or raw pointer reinterpretation introduced;
• the five user-frozen large objects and all Claude-authored Markdown are outside this checkpoint's diff.
