+# Xbox detail-object profile-end recovery (2026-08-27)
+
+## Result
+
+The first and only ordinary code-producing candidate makes
+`__rasterizer_detail_objects_end` strict exact in
+`source/rasterizer/xbox/rasterizer_xbox_detail_objects.obj`. The object
+advances from 0/20 to 1/20 exact functions and from 0/4,081 to 9/4,081
+meaningful code bytes. It remains `NonMatching`; no data, completion-label,
+semantic-exception, or parked-function credit is claimed.
+
+## Frozen target and source evidence
+
+January's complete function is a nine-byte cdecl leaf followed by seven NOP
+padding bytes:
+
+```text
+push 0x15
+call _rasterizer_profile_end
+pop  ecx
+ret
+```
+
+The target symbol is external storage class 2/type `0x20`; its lone relocation
+is zero-addend `REL32` at function offset `+0x03`. Current
+`source/rasterizer/rasterizer.c` independently proves that the public
+`rasterizer_detail_objects_end(void)` wrapper calls this Xbox backend owner.
+Current `rasterizer_xbox.h` and multiple existing backend users prove the
+callee signature `void rasterizer_profile_end(short)`.
+
+The HCEA later-platform sources were searched. They corroborate the public and
+private `void(void)` split but implement the backend as an empty platform stub,
+so they supply signature/topology provenance only and no January byte claim.
+All registered Claude worktrees and current object ledgers were searched; none
+contained a prior body or production attempt for this function.
+
+## Retained typed source
+
+The source-local prototype avoids importing unrelated Xbox header state into
+this otherwise empty translation unit:
+
+```c
+void rasterizer_profile_end(
+	short profile);
+
+void _rasterizer_detail_objects_end(
+	void)
+{
+	rasterizer_profile_end(21);
+	return;
+}
+```
+
+The no-argument layout, one-parameter-per-line declaration, and explicit
+terminal return follow the current house rules. The body contains no assembly,
+`register`, `volatile`, optimizer barrier, pragma, intrinsic, attribute, raw
+address, pointer/integer reconstruction, pointer or union pun, undefined
+behavior, synthetic anchor, object patch, comparator exception, or byte
+forcing.

+
+The hardened comparator proves all 16 padded bytes, relocation count, address,

+share normalized SHA-256
+`80465da1be06ad7ef44824e4382cd8b4b5401f72d33e2346c424abf92ed3fbda`.
+The exact-set comparison reports this function as the sole `newly_exact`
+owner and reports no lost exact function.
+
+## One-shot discipline and validation
+
+`git diff --check` and the production compiler's no-output `/Zs` syntax check
+passed before emission. Exactly one normal selected-object compiler edge then
+produced the retained artifact. No spelling, prototype, constant, declaration,
+flag, or compiler retry occurred.
+
+The complete graph and campaign gates pass:
+
+- 377/833 complete objects overall and 275/468 for Halo;
+- 510,790/2,198,102 meaningful code bytes and 4,233/11,060 functions overall;
+- 497,876/1,770,166 Halo code bytes and 4,066/7,574 Halo functions;
+- data unchanged at 1,836,762/4,176,062 overall;
+- semantic audit: 470 units, 4,345 functions evaluated, 4,199 semantic exact,
+  4,259 accepted exact, and zero unit errors;
+- admission: zero candidates, contradictions, or revocations;
+- parks: three active, zero stale, zero invalid;
+- tooling tests: 179/179 pass, with only the inherited pytest cache-permission
+  warning.
+
+January COFF remains the sole admission authority. No protected path,
+configuration entry, completion label, push, amend, or history rewrite is
+involved.
