bitmaps.obj palette checkpoint

Result

The checkpoint is intentionally partial and source/bitmaps/bitmaps.c remains NonMatching.

• _bitmap_type_get_string: strict exact, 112 meaningful/padded bytes and 11 relocations.
• _bitmap_format_get_string: strict exact, 118 meaningful bytes, 128 padded bytes, and 11 relocations.
• _global_vector_palette: strict exact as the complete target-owned .data section, 1,116 bytes and 21 relocations.
• Ordinary progress gain: 230 code bytes and two functions. The exact partial data section is recorded here but is not credited globally because the conservative progress ledger only credits a partial unit's entire remaining unmatched-data span.

The retained source contains no assembly, volatile access, force-inline spelling, compiler pragma/barrier, raw offset, or type-punning device.

Independent target evidence

The January split object and PDB/config symbol map are authoritative. Demon was used only to identify a candidate 256-entry vector palette. Parsing those 256 words and comparing them with the first 1,024 bytes of the target section gave the same SHA-256 on both sides:

b58960eb51a53850a9145e1f7e8c1123af23a47c6e18bf6f723a40323dad1517

The apparent 92-byte discrepancy is not unexplained palette padding. Target relocations and the first two target functions prove this exact layout:

Offset	Size	Meaning	Relocations
0x000	1,024	256 writable pixel32 palette entries	0
0x400	16	three bitmap-type names plus a null sentinel	3
0x410	76	eighteen bitmap-format names plus a null sentinel	18

_bitmap_type_get_string reads the table at 0x400 and checks the sentinel at 0x40c. _bitmap_format_get_string reads the table at 0x410 and checks the sentinel at 0x458. The rebuilt section consequently has the target's exact size, normalized bytes, relocation addresses/types/destinations/addends, and public owner _global_vector_palette:

443063631e6958ff5026be3038f8785d61eee4073cb01b8eaa4fdfcc3b620002

The compiler emits five referenced string literals as candidate COMDAT definitions that csplit represents as undefined imports because the linked image coalesced them under another object. They are not part of the target-owned section claim. Eighteen additional target-owned read-only literal sections (440 bytes) compare strict exact by their compiler symbol names.

Fail-closed boundary

_bitmap_format_get_bits_per_pixel was reconstructed experimentally with identical padded bytes and relocation locations/types. It was removed from the checkpoint because its readable local table symbol did not compare strictly to csplit's synthetic _rdata_002544cc owner. No semantic credit or address-based identifier was retained to hide that ownership mismatch.

The lane began at integration commit a5f816f2d862642e0304e5d488bd23b6c5d948e9. Full Halo/libcmt builds, the strict semantic report, object-admission audit, parked-function validation, and all 179 tool tests passed. A clean one-unit regression snapshot is created only after the reviewed source and this ledger are committed.
