profile.obj Codex checkpoint

This Codex-owned ledger records the bounded, header-free recovery of source/cseries/profile.obj. The unit remains NonMatching: 30 functions and most initialized data are still open. No pre-existing or Claude-authored Markdown was edited or deleted.

Scope and donor boundary

• Integration base: 664ce784eae6bbeded627097d9627fcc11091328.
• Safety-correction base: 472fe0e0b272d6da7e7c289a97ac80fca56c0b0a.
• The historical donor chain runs from be2e5bc2 through 3c2a9168; its final profile.c blob is 50f0976a1c647b9137e4bc798877453322f9c14c.
• The donor measured 30/44 exact functions. Thirteen of those bodies depend on the donor's inline rdtsc assembly macro and were excluded. The section-history helpers _code_0007dd20 and _find_profile_section were also excluded because their typed implementation requires broadening the shared profile_section layout in profile.h.
• The retained frame, timer, iterator, and global layouts are private to profile.c. There is no profile.h, render caller, shared-header, configuration, semantic-ledger, or park delta.
• The user-frozen vehicles, ai_debug, ai_script, actions, and units objects are outside this lane and untouched.

Strict code result

The untouched base had 0/44 strict-exact functions and zero credited code bytes. A forced candidate build accepts 14/44 functions totaling 1,117 meaningful bytes, 1,232 padded bytes, and 85 relocations. Every accepted body is ordinary objdiff exact and independently semantic-COFF exact; no exception ledger is used.

Thirteen exact public functions have matching whole-symbol function type and external storage. The private _code_0007ee30 code section is exact, but the target split symbol has external storage class 2 while the legal source-static definition has class 3. This checkpoint does not claim whole-symbol ownership for that helper.

profile_dump_to_file remains a necessary public body because hs.c calls it. The target-shaped form called fclose even when fopen returned NULL. The retained implementation closes the stream only in the successful-open branch, so it is ordinary defined C but deliberately receives zero strict credit: it is 128 padded bytes with nine relocations and normalized SHA-256 c1c2e7ef1e9547f36d70b457fe9f1201fbd3cb5c4f4f6cebb277fd009dafaa21 rather than the target hash.

One bounded advisory test moved the profile_frame_get_stalls range assertions ahead of forming the frame pointer. That changed the normalized function hash to 305f28e627e0d6e72a83a17ff25535dd1fd2c52187ee6ded07d46d0df6807dd0, so the experiment was reverted. The exact body retains the original caller precondition that the iterator and its current index are valid on entry; its assertions reproduce the target diagnostics and are not a safety guard.

Strict data and ownership boundary

The target reports 1,131,932 data bytes: the 1,129,812-byte BSS aggregate is byte-exact at both the untouched base and candidate, while 2,120 aligned bytes of initialized/RDATA ownership remain uncredited by ordinary progress. The candidate adds seven independently strict target-owned RDATA COMDATs totaling 285 logical bytes and zero relocations:

Exact payload	Logical bytes
*	2
%s\r\n	5
d:\\profile.txt	15
game-value argument assertion	32
January source path	33
frame-history current-index assertion	78
frame-history range assertion	120

The untouched base owned none of those seven complete sections. The private profile_globals BSS owner has the same target layout and zero payload, but the target split symbol uses storage class 2 while the natural source-static owner uses class 3; whole-symbol ownership is therefore not claimed for that aggregate. Candidate/target symbol inventories are 75/298 entries. Extra compiler/debug/directive sections receive no target runtime credit.

Source quality and gates

The retained code is readable typed C. It uses no assembly, volatile scheduling device, forced inline, optimizer pragma/barrier, undefined type-punning, byte forcing, or repeated raw layout cast. Parameters follow the one-per-line convention, no-argument functions use the project layout, and void functions end with explicit return;.

The full Halo and libcmt build graphs pass. Semantic audit reports 470 units, 3,865 functions evaluated, 3,724 semantic exact, 3,788 accepted exact, and zero unit errors. Campaign progress is 375/833 complete objects, 3,777/11,060 exact functions, 460,855/2,198,102 exact code bytes, and 1,803,160/4,176,062 matched data bytes. Admission reports zero candidates and zero revocations, with only the inherited source/shell/shell_xbox contradiction. Parked audit reports three active, zero stale, and zero invalid. The complete tool suite passes 179/179 tests.

The unit remains NonMatching; no GitHub push is performed.
