D1: paired atoms epilogue (no TMEM round-trip)
...
Replace NO-OP round-trip + normalize + epilogue_tma_store with:
- get_tmem_load_op + get_smem_store_op paired atoms
- One-way TMEM→reg (normalize) →SMEM→GMEM
- Eliminates ~3% error from TMEM layout mismatch
- O rescale disabled (single KV tile only for now)
- Pre-computed TMA partitions outside if blocks

D1: N-tile support for HEAD_DIM>256
...
- pv_n_tile = min(head_dim, 256) — MMA instruction N limit
- n_pv_tiles = head_dim // pv_n_tile — outer loop count
- V FMHA layout uses pv_n_tile (not head_dim) for N-tile slicing
- Test loops over N-tiles at Python level, kernel processes (128, pv_n_tile)
- For hd=512: 2 kernel launches with V[:,0:256] and V[:,256:512]

D1: Parameterize HEAD_DIM in FmhaKernel (64→512)
...
- Promote HEAD_DIM from module constant to constructor parameter
- FmhaKernel(head_dim=64, s_k=128, ...) — default 64 for regression
- All references to HEAD_DIM replaced with self.head_dim
- PV MMA tiler, V layout, softmax corr_tiles all parameterized
- TMEM budget warning when num_tmem_alloc_cols > 512
- New test: test_fmha_v3_stage_d1.py tests hd=64 (regression) and hd=512
- Stage C test preserved as-is for reference
