# Explicit operand indexing

Codegen release suite: 320 passed, 5 ignored; doctest passed.
Workspace check passed without warnings.

New regressions cover multi-result residual/statistics calls with several rows
per tile, result-relative operand indexing, aliases and complete row coverage;
and the distinction between a singleton batch shard and a broadcast dimension.
Existing randomized broadcast, packed pointwise, borrowed-scalar, cast, GEMM,
attention, Repeat and placement tests also pass.

| Hardware fixture | Maximum absolute error | Minimum cosine | Modeled total cycles | Modeled exchange cycles |
|---|---:|---:|---:|---:|
| F16 small MLP, Repeat 3 | 0.000183 | — | 32613 | 18087 |
| FP8 small ViT, 3 layers, fused QKV | 0.189453 | 0.997459656 | 331874 | 120708 |

Both hardware reference tests passed, matching the indexed-results fixtures.
These are randomized small fixtures, not trained model accuracy results. Cycle
counts above are modeled, not measured execution times. Exact commands, logs
and binary profiles are adjacent.
