Promote daObjKm3_Kuruma_c intact translation unit

[andrewboudreau]

Promotes the five-function daObjKm3_Kuruma_c unit from per-symbol sources into one production intact C++ translation unit. The compiler now owns D1/D0, InitResources, CleanupResources, RTTI, type name, resource descriptor, SpawnInfo, and vtable; no D2 is emitted. RickshawPlatformBs_Spawn remains an explicit C-linkage ABI seam because the ROM proves the factory boundary but not a natural-new spelling.

Restacked directly onto current main after #2103, #2117, #2104, and #2129 landed. The branch contains only the Kuruma promotion commit.

Fresh exact proof on head 6b9a8bf: 11,088/11,088 source-built functions, 7/7 source-owned data claims, 106/106 modules, zero mismatches, intact-TU storage aliases exact, 570 ROM-data symbols verified, and stock ROM SHA-256 D1506E90EFAE5E2D2CF119926A4AC2A291BD5CA78349D09D5024E1A918C478E8. The generated TU state note is current; 98/98 shadow TUs compile; port references are 405/405; all eight merge-result static gates stay green; attribution reports three consolidations intact with zero changed or lost credit.

No CLAIMS.md, match_attempts.jsonl, or bot dashboard artifacts are included.

Byte-verified means the range carries complete in a delinks.txt, so the ROM build compiled it and compared it to the cartridge. The 494 claimed functions have a src/ file named after the symbol with no NONMATCHING banner, and nothing compiles them -- dsd fills their addresses with the ROM's own bytes. Both together are the 11,217 this project calls matched.

Temporarily draft after repairing the #2117 root. I replayed only the Kuruma commit onto current main plus clean #2117 and ran the full ROM gate. The strict control passed 106/106 with the stock SHA, but the candidate was correctly rejected: current main lacks the #2103 nontextSectionOrder implementation, so Kuruma RTTI and resource sections reorder and produce wrong-symbol and wrong-destination relocation failures. I did not push that invalid candidate; it is preserved locally as wip/kuruma-main-root-needs-section-order-20260901. Once the #2103 section-order tooling lands, I will re-cut Kuruma on the clean root and rerun the complete ROM proof.

[andrewboudreau]

The former draft blocker is cleared: #2103 and #2117 are now in main. I replayed only the Kuruma promotion onto current main, resolved attribution semantically, regenerated the TU state note, and reran the complete proof on head 0804918.

Fresh results: canonical ROM SHA, 11,088/11,088 functions, 7/7 source-data claims, 106/106 modules, zero mismatches, 98/98 TUs, 405/405 port refs, and 8/8 merge-result static gates. The PR is ready for fresh independent validation.

[andrewboudreau]

The prior private validation passed, but #2129 merged while it was running and made that head conflict with main. I did not merge the stale head.

I rebased the single Kuruma commit onto post-Waterfall main c9453b4, retained Waterfall ledger state, regenerated the TU state note, and reran the complete proof. New head 6b9a8bf passes the canonical ROM build: 11,088/11,088 functions, 7/7 source-data claims, 106/106 modules, zero mismatches, 570 verified ROM-data symbols, 98/98 TUs, 405/405 port refs, and 8/8 merge-result static gates. Awaiting fresh private validation on this exact head.
