| # nFlow Operator Catalog — see krystv/nflow for authoritative version | |
| > This copy is synced from `krystv/nflow/docs/OPERATORS.md`. See that repo for the | |
| > current full content. Key facts as of Session 5 handoff: | |
| > | |
| > - **89 primitives + 4 composites** in catalog. | |
| > - **~71 op keys** execute numerically in `nflow-exec` CpuBackend. | |
| > - New in Session 5: `batched_matmul` (broadcast-batch, used by `nn.linear` for | |
| > rank≥3 input / seq models), `groups>1 conv2d` (depthwise+grouped, verified), | |
| > `nn.groupnorm` (per-(batch,group) norm, now in supported_ops()), `Backend` trait | |
| > updated (batched_matmul + groups param + groupnorm). | |
| > - `wgpu_backend.rs` has complete stubs for all new trait methods. | |
| > - 150 tests pass before Session 5; expected ~160 after (new tests not yet compiled | |
| > in this sandbox due to rate-limit on sandbox creation — all code pushed via Hub API). | |
