Omar SobhandClaude Opus 5	9575b84803	style: clear the fmt gate and two lib clippy warnings ... Deferred deliberately while the TWIN-2B/2C campaign had live marches: each march is a fresh `cargo test` invocation, so reformatting `turek_hron_fsi2.rs` mid-campaign would have forced a test-binary rebuild and cost comparability for a cosmetic gate. The family closed, so this is now free. - `cargo fmt --all` across 8 files that had drifted (including the FSI2/FSI3 harnesses touched by the UMEAN/ES override commits). - `rtx-feature-store/tests/integration_tests.rs` had trailing whitespace rustfmt refused to format around ("left behind trailing whitespace" internal error), so the whole file was being skipped; stripped it and the file formats now. - Two `unnecessary_parentheses` warnings in the rtx-transformers lib (`continual/progressive.rs`, `curriculum/mod.rs`) — these were the only rustytorch warnings surfacing through omni-cortex's workspace clippy gate, which is how they were found. No behaviour change. rtx-fsi test binaries still build.

quantumandClaude Fable 5	c36cf2f8a7	rtx-backend-metal: fix swap_dims returning a corrupt strided view ... swap_dims copied the buffer but wrote elements back at their ORIGINAL positions (new_idx was computed with the swapped strides), returning a stride-swapped non-contiguous tensor. Every other op in this backend — elementwise kernels, MPS matmul, to_vec — reads raw buffers and ignores strides, so any transpose consumer (notably the autograd matmul backward, grad_a = grad_c @ b^T) silently computed on untransposed data. Found via CPU-vs-Metal gradient parity on the DigiGraph HetGAT: forward matched, gradients were ~2x off. swap_dims now physically permutes into a contiguous result (reading through the input's strides + offset), and reshape asserts contiguity instead of silently reinterpreting a non-contiguous buffer. 3 new parity tests incl. matmul-after-transpose (25 total pass on-device).

quantumandClaude Fable 5	9297976929	rtx-backend-metal: GPU index_select / index_add via one-hot CSR SpMM ... Override the Backend trait's host-round-trip defaults: gather is S @ X with S the [E x N] one-hot selection CSR; scatter-add is the adjoint S^T @ X, whose CSR is built directly by counting sort so duplicate indices land in one row and the spmm kernel (one thread per output element) accumulates them without atomics. CSR matrices are cached per thread keyed by the exact index list + dims, so a static graph topology (GNN message passing) builds each matrix once. Host fallback on degenerate shapes or any sparse-pipeline failure. 13 new parity tests vs CPU reference: duplicates, unreferenced rows, D=1/2/3, 15k x 5k x 64 gather/scatter, cache reuse, adjoint roundtrip. Verified on-device that the SpMM path (not the fallback) serves all 13. Co-Authored-By: Claude Fable 5 <[email protected]>	2026-08-21 05:56:23 -07:00
