+## Phase 8 Ragged MoE Dispatch Safety Rerun
+
+Phase 8 had already closed the live ragged MoE helper path by profile:
+`mm_ids=0.66%`, `gather_mmq=0.42%`, while `mmq_nvfp4=22.36%` and
+`act_quant=3.60%`. The only source patch kept from the phase is the test gate
+(`0053-test-paged-cover-ragged-MoE-dispatch.patch`); the metadata-only
+`LLAMA_MOE_FUSED_DISPATCH` shortcut is rejected.

+Conclusion:

+- The inferencing gates remain canonical on the unchanged production path.
+- Do not add a metadata/helper-only fused-dispatch hook. A future Phase 8
+  production candidate must reduce `mmq_nvfp4` or activation movement directly,
+  stay free of D2H id readback and new stream synchronizations, and then pass
+  the same md5/op gates before any serving A/B is considered.

+### Phase 8 ragged MoE dispatch closure
+
+The remaining Phase 8 source shortcut was closed without production CUDA edits.
+The live ragged serving profile showed helper metadata buckets too small to clear
+the `+5%` serving A/B gate (`mm_ids=0.66%`, `gather_mmq=0.42%`). Patch `0023`
+already handles the broadcast-activation NVFP4 path by quantizing unique tokens
+once and gathering FP4 blocks, so a metadata-only `LLAMA_MOE_FUSED_DISPATCH`
+hook would add conflict surface without attacking the dominant buckets.

+- Keep test patch `0053`.
+- Do not add a Phase 8 production patch unless it directly reduces
+  `mmq_nvfp4` or activation movement without D2H id readback, new
+  synchronizations, or md5 drift.
