Source reconstruction

• Six-route HIP source: kernel/rdna35_lowbit.hip
• Qualified HSACO: kernel/rdna35_lowbit.hsaco
• vLLM full composition: apply adapters/vllm-v16-full.patch directly to public upstream commit 4bdc8a788d2e2ce9165d552b3d4d8b72604626bf
• SGLang adapter: apply adapters/sglang.patch to f63458b5beaceabbd9d749b9fc956370e1b649e6
• Recursive source identities: provenance/

The vLLM public-base patch reconstructs the exact 6,383-file public source root fd7d2374b2f51c65cfe2bfc8a6ce02a0f04f82f1a69f55db2b6e804c0a8f097f. The only post-build source change is test-fixture sanitization in tests/quantization/test_gfx1151_archive_port_contract.py; tests are absent from the wheel.

Physical qualification

• Direct six-route native gfx1151: qualification/direct-gfx1151-final-v0.1.0.json
• Final vLLM W4A8 request route: qualification/vllm-full-w4a8-final-v0.1.0.json
• Final SGLang W4A8 request route: qualification/sglang-full-w4a8-final-v0.1.0.json

Both framework receipts return exact RDNA35_OK, cover 16 eligible layers, use the qualified module hash, complete asynchronously through hipEventRecord+hipEventSynchronize, and report zero fallback or foreign request rows.

Limits

• Reference correctness/dispatch routes, not claimed tuned GEMMs or performance wins.
• No broad model-quality claim.
• Archived W4A4 subpack remains disabled by default. Its retained counts are a historical summary; the underlying matrix/evidence index is not bundled, so this release makes no current archive functional, quality or performance qualification claim.
• No production activation or promotion authority.
• Requires the matching HaloLoom ROCm 10/Torch/framework dependency closure; do not install framework wheels into an empty environment with --no-deps.
