D1.5: Replace TMEM round-trip normalize with correction epilog (one-way: TMEM→reg→SMEM→GMEM)
...
- Remove noop + normalize TMEM round-trips (3% error per trip)
- Use epilogue_tmem_copy_and_partition for TMEM→reg (paired atoms)
- Use epilogue_smem_copy_and_partition for reg→SMEM (paired atoms)
- Apply 1/row_sum normalization in register space (exact)
- TMA store from SMEM→GMEM (no TMEM write-back)
- Add iter_acc_early_release_in_epilogue attribute
- Update SMEM-P comments to reflect coordinate-indexed fallback
