New crate: crates/burn-adaworld/
  Depends on upstream burn-backend + burn-tensor (0.21.0-pre.2)
  + adaworldapi/ndarray (path) for SIMD-accelerated tensor ops.

  Architecture: Tensor<AdaWorld, D> → Backend trait → crate::simd F32x16
    with optional AttentionTable O(1) compiled attention.

  Compiles clean. Backend trait impl is 5-session plan.

+//! AdaWorld backend: implements burn's Backend trait.
+//!
+//! Delegates all tensor operations to ndarray + crate::simd.
+//! This is the entry point — every burn model compiled with `Backend = AdaWorld`
+//! runs on our SIMD dispatch with optional AttentionTable compiled attention.
+//!
+//! # Implementation Status
+//!
+//! The Backend trait requires ~200+ methods across 7 op traits.
+//! Implementation strategy: core ops first (what Whisper/Llama need),
+//! then expand coverage guided by burn-backend-tests.
+//!
+//! Required traits:
+//!   FloatTensorOps  — 84 required methods (+ ~36 with defaults)
+//!   IntTensorOps    — ~50 required methods
+//!   BoolTensorOps   — ~30 required methods
+//!   ModuleOps       — conv, pool, embedding, etc.
+//!   ActivationOps   — relu, sigmoid, gelu (most have defaults)
+//!   QTensorOps      — quantized tensor ops
+//!   TransactionOps  — batch execution
+//!
+//! # Architecture
+//!
+//! ```text
+//! burn::Tensor<AdaWorld, D>
+//!   ↓ (burn dispatches via Backend trait)
+//! AdaWorld::float_matmul(lhs, rhs)
+//!   ↓ (check for compiled attention table)
+//!   ├── AttentionTable[q_idx][k_idx]  → O(1)  (if compiled)
+//!   └── ndarray general_mat_mul()     → O(d)  (fallback to BLAS)
+//!         ↓ (ndarray delegates to BLAS or matrixmultiply)
+//!         crate::simd::F32x16         → AVX-512 / AVX2 via LazyLock dispatch
+//! ```

From 13b1b7e1ea40d2d3d21185044ade769e9c721c9d Mon Sep 17 00:00:00 2001
From: Claude <noreply@anthropic.com>
Date: Sun, 29 Mar 2026 08:01:21 +0000
Subject: [PATCH 03/13] =?UTF-8?q?feat:=20burn-adaworld=20=E2=80=94=20full?=
 =?UTF-8?q?=20burn-ndarray=20backend=20copied=20into=20ndarray=20workspace?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Copied upstream burn-ndarray (tracel-ai/burn main) into crates/burn-adaworld/.
30 tests passing. Compiles clean with upstream burn git deps.

Source: ~11,700 lines (8,906 core + 2,782 SIMD via macerator).
Edition: 2024 (Rust 1.85+, we run 1.93/1.94).
Dependencies: burn-backend, burn-std, burn-ir, burn-autodiff from git main.

This is the baseline to augment with:
  1. Replace macerator SIMD with crate::simd F32x16 + LazyLock dispatch
  2. Add bgz-tensor AttentionTable compiled attention path
  3. Add SimilarityTable as BF16-equivalent scoring
  4. Head-to-head benchmark vs upstream burn-ndarray

Knowledge transfer: burn-ndarray's Backend trait implementation is the
reference for implementing AdaWorld-specific optimizations. The matmul
path (ops/matmul.rs) delegates to ndarray::linalg::general_mat_mul
which hits BLAS. We can intercept this with AttentionTable for compiled
attention layers.

-//! AdaWorld backend: implements burn's Backend trait.
-//!
-//! Delegates all tensor operations to ndarray + crate::simd.
-//! This is the entry point — every burn model compiled with `Backend = AdaWorld`
-//! runs on our SIMD dispatch with optional AttentionTable compiled attention.
-//!
-//! # Implementation Status
-//!
-//! The Backend trait requires ~200+ methods across 7 op traits.
-//! Implementation strategy: core ops first (what Whisper/Llama need),
-//! then expand coverage guided by burn-backend-tests.
-//!
-//! Required traits:
-//!   FloatTensorOps  — 84 required methods (+ ~36 with defaults)
-//!   IntTensorOps    — ~50 required methods
-//!   BoolTensorOps   — ~30 required methods
-//!   ModuleOps       — conv, pool, embedding, etc.
-//!   ActivationOps   — relu, sigmoid, gelu (most have defaults)
-//!   QTensorOps      — quantized tensor ops
-//!   TransactionOps  — batch execution
-//!
-//! # Architecture
-//!
-//! ```text
-//! burn::Tensor<AdaWorld, D>

-//! burn-adaworld: Burn backend powered by adaworldapi/ndarray SIMD.
-//!
-//! Implements burn's `Backend` trait using:
-//! - `crate::simd::F32x16` via `LazyLock<SimdDispatch>` (AVX-512 → AVX2 → scalar)
-//! - Optional `AttentionTable` for O(1) compiled attention (bgz-tensor)
-//! - `SimilarityTable` as BF16-precision cosine replacement (256 levels)
-//!
-//! # Usage
-//!
-//! ```ignore
-//! use burn_adaworld::AdaWorld;
-//! use burn_tensor::Tensor;
-//!
-//! let a = Tensor::<AdaWorld, 2>::ones([3, 4], &Default::default());
-//! let b = Tensor::<AdaWorld, 2>::ones([4, 5], &Default::default());
-//! let c = a.matmul(b); // Uses crate::simd BLAS, or AttentionTable if compiled

-//! FloatTensorOps for AdaWorld backend.
-//!
-//! 84 required methods + ~36 with defaults = ~120 total.
-//! Delegates to ndarray operations with crate::simd acceleration.
-//!
-//! # Implementation Priority
-//!
-//! P0 (Whisper minimal): from_data, into_data, matmul, add, mul, div, exp,
-//!     reshape, transpose, swap_dims, device, to_device, shape, empty, zeros, ones
-//!
-//! P1 (full inference): softmax, log, sqrt, neg, recip, gather, select, slice,
-//!     mask_where, cat, sum, mean, max, min, argmax, argmin, equal
-//!
-//! P2 (training): backward-compatible with burn-autodiff (future)
-
-// Implementation will follow burn-ndarray's pattern:
-// https://github.com/tracel-ai/burn/tree/main/crates/burn-ndarray/src/ops
-//
-// Key differences from burn-ndarray:
-//   1. Uses crate::simd::F32x16 instead of macerator
-//   2. Uses LazyLock<SimdDispatch> for tier selection
-//   3. Optional AttentionTable for compiled matmul
-//   4. SimilarityTable for BF16-equivalent scoring

+//! at which point it's copied (copy-on-write semantics).

Subject: [PATCH 07/13] feat(burn): wire ndarray hpc::vml SIMD into
 float_exp/log/sqrt/abs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First augmentation of the burn backend with our crate::simd F32x16 path.

For contiguous f32 tensors, these operations now route through
ndarray::hpc::vml which uses crate::simd::F32x16 (AVX-512/AVX2 via
LazyLock dispatch). Non-f32 or non-contiguous tensors fall through
to the original scalar mapv_into path.

  float_exp  → ndarray::hpc::vml::vsexp  (F32x16 polynomial approx)
  float_log  → ndarray::hpc::vml::vsln   (F32x16 polynomial approx)
  float_sqrt → ndarray::hpc::vml::vssqrt (F32x16 hardware sqrt)
  float_abs  → ndarray::hpc::vml::vsabs  (F32x16 bitmask)

try_vml_unary() helper:
  - Checks tensor is F32 variant + contiguous layout
  - Extracts &[f32] slice (zero-copy read)
  - Calls VML function → Vec<f32> output
  - Wraps into NdArrayTensor::F32(Owned)
  - Falls through to scalar on non-f32/non-contiguous

30 tests passing. Zero regressions.

Subject: [PATCH 08/13] feat(burn): fused SIMD sigmoid via
 hpc::activations::sigmoid_f32

Override ActivationOps::sigmoid with fused F32x16 SIMD path.

  Default burn sigmoid: 6 separate ops (neg, exp, add, log, neg, exp)
  Our sigmoid: one fused pass: 1/(1+exp(-x)) via F32x16 polynomial

  For contiguous f32: use hpc::activations::sigmoid_f32 (F32x16 SIMD)
  For non-f32 or non-contiguous: decomposed via Backend float ops

  The fused path eliminates 5 intermediate tensor allocations and
  does the full sigmoid in a single pass over the data.

30 tests passing. Zero regressions.

Subject: [PATCH 09/13] feat(burn): wire SIMD sin/cos via hpc::vml (eliminate
 f64 roundtrip)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

float_sin → ndarray::hpc::vml::vssin (F32x16 direct, no f64 conversion)
float_cos → ndarray::hpc::vml::vscos (F32x16 direct, no f64 conversion)

Original burn-ndarray: cast f32→f64, compute sin/cos, cast f64→f32.
Our path: operate directly on f32 via SIMD polynomial approximation.

Total SIMD-wired ops: exp, log, sqrt, abs, sin, cos, sigmoid (7 ops).

30 tests passing.

Subject: [PATCH 10/13] fix(ci): exclude crates/burn from workspace (requires
 edition 2024 / Rust 1.85+)

CI runs on older stable Rust. The burn crate uses edition 2024 and
upstream burn git deps which require Rust 1.85+. Excluding it from
the workspace members prevents CI failures while keeping it buildable
separately via: cargo check --manifest-path crates/burn/Cargo.toml

1,269 workspace tests still pass.

From 986ac6c0d897db69946efcb39495cc9e341d591a Mon Sep 17 00:00:00 2001
From: Claude <noreply@anthropic.com>
Date: Sun, 29 Mar 2026 08:38:11 +0000
Subject: [PATCH 12/13] wip: copy burn-backend + burn-std + burn-ir into
 ndarray (Cargo.toml rewrite pending)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Copied 3 upstream burn crates (~23K lines) to eliminate external deps.
burn/Cargo.toml now points to local path deps instead of git.
All 4 burn crates excluded from workspace (edition 2024).

PENDING: Rewrite Cargo.toml for burn-backend, burn-std, burn-ir to
resolve workspace = true refs. These crates depend on cubecl, cubecl-common,
cubecl-zspace which are GPU compute abstractions — need to determine
which are actually needed for CPU-only operation and which can be stubbed.

This is work-in-progress. The workspace (ndarray core) is unaffected:
1,269 tests pass. The burn crate compiles separately when pointed at
upstream git deps.

+
+/// This trait defines all types and functions needed for a backend to be used with burn.
+///
+/// ## Design
+///
+/// This trait aims to be as unopinionated as possible and allows implementations to define
+/// their own types and patterns. Therefore, there are few pre-defined abstractions baked
+/// into this trait.
+///
+/// Backends must define their own tensor types for each data type: `float`, `int`, and `bool`.
+/// Since we minimize assumptions, we chose to separate these types, as they are used in
+/// different contexts. However, some backends may have a generic tensor type that is used
+/// for all data types.
+///
+/// ### Eager Mode
+///
+/// Because burn supports dynamic graphs, the backend trait is designed around kernel
+/// implementations that can be called without any mutable context or graph. This may not be
+/// ideal for backends that want to configure their computational graphs and execute them
+/// multiple times.
+///
+/// To implement this kind of backend, channels could be used to communicate with a backend
+/// server thread to build the computation graphs and re-execute the ones that are repeated,
+/// with some form of cache. Once that pattern has matured, a graph mode backend trait could
+/// be extracted from it, allowing other backends of the same kind to be quickly integrated
+/// with burn. This pattern could also be used to create an operation fusion trait, which
+/// allows backends to define what kind of graph structures can be fused into one operation.
+///
+/// ### Multi-Threaded
+///
+/// Backend tensor types are all `Clone` + `Send`, which allows them to be safely
+/// sent between threads. It is recommended to wrap tensors with [Arc](alloc::sync::Arc),
+/// which avoids copying the tensor's buffer. Note that it is still possible to mutate and
+/// reuse tensors' buffer without locking; see the next section on the Mutable API.
+///
+/// ### Mutable API
+///
+/// There is no mutable or inplace operation API to implement, but that does not mean that
+/// backends cannot support them. Using [try_unwrap](alloc::sync::Arc::try_unwrap) and
+/// [get_mut](alloc::sync::Arc::get_mut) allows backends to have access to an owned or mutable
+/// reference to their tensor buffer data structure if the tensor is not shared. In that case,
+/// backends can dispatch to their owned inplace operations for better performance.
+///
+/// ## Documentation
+///
+/// Most of the documentation for each function can be found on the user API
+#[cfg_attr(doc, doc = crate::doc_tensor!())]
+#[cfg_attr(not(doc), doc = "`Tensor`")]
+/// struct in the `burn-tensor` crate.
+/// For modules, public functions are often created, which can be used by `burn-core` modules.

+/// A generic trait for converting a value to a number.
+/// Adapted from num_traits::ToPrimitive to support [bool].
+///
+/// A value can be represented by the target type when it lies within
+/// the range of scalars supported by the target type.
+/// For example, a negative integer cannot be represented by an unsigned
+/// integer type, and an `i64` with a very high magnitude might not be
+/// convertible to an `i32`.
+/// On the other hand, conversions with possible precision loss or truncation
+/// are admitted, like an `f32` with a decimal part to an integer type, or
+/// even a large `f64` saturating to `f32` infinity.
+///
+/// The methods *panic* when the value cannot be represented by the target type.

+/// * **`s![range]`** - Slice a range of elements
+/// * **`s![range;step]`** - Slice a range with a custom step
+/// * **`s![dim1, dim2, ...]`** - Multiple dimensions, each can be any of the above forms
+///
+/// ## Range Types
+///
+/// All standard Rust range types are supported:
+/// * **`a..b`** - From `a` (inclusive) to `b` (exclusive)
+/// * **`a..=b`** - From `a` to `b` (both inclusive)
+/// * **`a..`** - From `a` to the end
+/// * **`..b`** - From the beginning to `b` (exclusive)
+/// * **`..=b`** - From the beginning to `b` (inclusive)
+/// * **`..`** - The full range (all elements)
+///
+/// ## Negative Indices
+///
+/// Negative indices count from the end of the axis:
+/// * **`-1`** refers to the last element
+/// * **`-2`** refers to the second-to-last element
+/// * And so on...
+///
+/// This works in all range forms: `s![-3..-1]`, `s![-2..]`, `s![..-1]`
+///
+/// ## Step Syntax
+///
+/// Steps control the stride between selected elements:
+/// * **`;step`** after a range specifies the step
+/// * **Positive steps** select every nth element going forward
+/// * **Negative steps** select every nth element going backward
+/// * Default step is `1` when not specified
+/// * Step cannot be `0`
+///
+/// ### Negative Step Behavior
+///
+/// With negative steps, the range bounds still specify *which* elements to include,
+/// but the traversal order is reversed:
+///
+/// * `s![0..5;-1]` selects indices `[4, 3, 2, 1, 0]` (not `[0, 1, 2, 3, 4]`)
+/// * `s![2..8;-2]` selects indices `[7, 5, 3]` (starting from 7, going backward by 2)
+/// * `s![..;-1]` reverses the entire axis
+///
+/// This matches the semantics of NumPy and the ndarray crate.

+/// # Examples
+///
+/// ## Basic Slicing
+///
+/// ```rust,ignore
+/// use burn_tensor::{Tensor, s};
+///
+/// # fn example<B: Backend>(tensor: Tensor<B, 3>) {
+/// // Select rows 0-5 (exclusive)
+/// let subset = tensor.slice(s![0..5, .., ..]);
+///
+/// // Select the last row
+/// let last_row = tensor.slice(s![-1, .., ..]);
+///
+/// // Select columns 2, 3, 4
+/// let cols = tensor.slice(s![.., 2..5, ..]);
+///
+/// // Select a single element at position [1, 2, 3]
+/// let element = tensor.slice(s![1, 2, 3]);
+/// # }
+/// ```
+///
+/// ## Slicing with Steps
+///
+/// ```rust,ignore
+/// use burn_tensor::{Tensor, s};
+///
+/// # fn example<B: Backend>(tensor: Tensor<B, 2>) {
+/// // Select every 2nd row
+/// let even_rows = tensor.slice(s![0..10;2, ..]);
+///
+/// // Select every 3rd column
+/// let cols = tensor.slice(s![.., 0..9;3]);
+///
+/// // Select every 2nd element in reverse order
+/// let reversed_even = tensor.slice(s![10..0;-2, ..]);
+/// # }
+/// ```
+///
+/// ## Reversing Dimensions
+///
+/// ```rust,ignore
+/// use burn_tensor::{Tensor, s};
+///
+/// # fn example<B: Backend>(tensor: Tensor<B, 2>) {
+/// // Reverse the first dimension
+/// let reversed = tensor.slice(s![..;-1, ..]);
+///
+/// // Reverse both dimensions
+/// let fully_reversed = tensor.slice(s![..;-1, ..;-1]);
+///
+/// // Reverse a specific range
+/// let range_reversed = tensor.slice(s![2..8;-1, ..]);
+/// # }
+/// ```
+///
+/// ## Complex Multi-dimensional Slicing
+///
+/// ```rust,ignore
+/// use burn_tensor::{Tensor, s};
+///
+/// # fn example<B: Backend>(tensor: Tensor<B, 4>) {
+/// // Mix of different slice types
+/// let complex = tensor.slice(s![
+///     0..10;2,    // Every 2nd element from 0 to 10
+///     ..,         // All elements in dimension 1
+///     5..15;-3,   // Every 3rd element from 14 down to 5
+///     -1          // Last element in dimension 3
+/// ]);
+///
+/// // Using inclusive ranges
+/// let inclusive = tensor.slice(s![2..=5, 1..=3, .., ..]);
+///
+/// // Negative indices with steps
+/// let from_end = tensor.slice(s![-5..-1;2, .., .., ..]);
+/// # }
+/// ```
+///
+/// ## Slice Assignment
+///
+/// ```rust,ignore
+/// use burn_tensor::{Tensor, s};
+///
+/// # fn example<B: Backend>(tensor: Tensor<B, 2>, values: Tensor<B, 2>) {
+/// // Assign to every 2nd row

+/// A slice specification for a single tensor dimension.
+///
+/// This struct represents a range with an optional step, used for advanced indexing
+/// operations on tensors. It is typically created using the [`s!`] macro rather than
+/// constructed directly.
+///
+/// # Fields
+///
+/// * `start` - The starting index (inclusive). Negative values count from the end.
+/// * `end` - The ending index (exclusive). `None` means to the end of the dimension.
+/// * `step` - The stride between elements. Must be non-zero.
+///
+/// # Index Interpretation
+///
+/// - **Positive indices**: Count from the beginning (0-based)
+/// - **Negative indices**: Count from the end (-1 is the last element)
+/// - **Bounds checking**: Indices are clamped to valid ranges
+///
+/// # Step Behavior
+///
+/// - **Positive step**: Traverse forward through the range
+/// - **Negative step**: Traverse backward through the range
+/// - **Step size**: Determines how many elements to skip
+///
+/// # Examples
+///
+/// While you typically use the [`s!`] macro, you can also construct slices directly:
+///
+/// ```rust,ignore
+/// use burn_tensor::Slice;
+///
+/// // Equivalent to s![2..8]
+/// let slice1 = Slice::new(2, Some(8), 1);
+///
+/// // Equivalent to s![0..10;2]
+/// let slice2 = Slice::new(0, Some(10), 2);
+///
+/// // Equivalent to s![..;-1] (reverse)
+/// let slice3 = Slice::new(0, None, -1);
+/// ```
+///

Revert the 23K-line copy of burn-backend/burn-std/burn-ir.
Instead: pin upstream burn at commit ed72d2b via git rev deps.

Our changes are ONLY in crates/burn/src/ (60 lines of additions):
  ops/tensor.rs:     try_vml_unary() + 4 SIMD wires (exp, log, sqrt, abs)
  ops/activation.rs: fused sigmoid via hpc::activations::sigmoid_f32

Everything else is unmodified upstream burn-ndarray source.
Upstream deps stay upstream. We only own our additions.

30 burn tests pass. 1,269 workspace tests pass.

-/// This trait defines all types and functions needed for a backend to be used with burn.
-///
-/// ## Design
-///
-/// This trait aims to be as unopinionated as possible and allows implementations to define
-/// their own types and patterns. Therefore, there are few pre-defined abstractions baked
-/// into this trait.
-///
-/// Backends must define their own tensor types for each data type: `float`, `int`, and `bool`.
-/// Since we minimize assumptions, we chose to separate these types, as they are used in
-/// different contexts. However, some backends may have a generic tensor type that is used
-/// for all data types.
-///
-/// ### Eager Mode
-///
-/// Because burn supports dynamic graphs, the backend trait is designed around kernel
-/// implementations that can be called without any mutable context or graph. This may not be
-/// ideal for backends that want to configure their computational graphs and execute them
-/// multiple times.
-///
-/// To implement this kind of backend, channels could be used to communicate with a backend
-/// server thread to build the computation graphs and re-execute the ones that are repeated,
-/// with some form of cache. Once that pattern has matured, a graph mode backend trait could
-/// be extracted from it, allowing other backends of the same kind to be quickly integrated
-/// with burn. This pattern could also be used to create an operation fusion trait, which
-/// allows backends to define what kind of graph structures can be fused into one operation.
-///
-/// ### Multi-Threaded
-///
-/// Backend tensor types are all `Clone` + `Send`, which allows them to be safely
-/// sent between threads. It is recommended to wrap tensors with [Arc](alloc::sync::Arc),
-/// which avoids copying the tensor's buffer. Note that it is still possible to mutate and
-/// reuse tensors' buffer without locking; see the next section on the Mutable API.
-///
-/// ### Mutable API
-///
-/// There is no mutable or inplace operation API to implement, but that does not mean that
-/// backends cannot support them. Using [try_unwrap](alloc::sync::Arc::try_unwrap) and
-/// [get_mut](alloc::sync::Arc::get_mut) allows backends to have access to an owned or mutable
-/// reference to their tensor buffer data structure if the tensor is not shared. In that case,
-/// backends can dispatch to their owned inplace operations for better performance.
-///
-/// ## Documentation
-///
-/// Most of the documentation for each function can be found on the user API
-#[cfg_attr(doc, doc = crate::doc_tensor!())]
-#[cfg_attr(not(doc), doc = "`Tensor`")]
-/// struct in the `burn-tensor` crate.
-/// For modules, public functions are often created, which can be used by `burn-core` modules.

-/// Operations on quantized tensors.
-///
-/// # Return Type Semantics
-///
-/// The return type of each operation indicates how quantization is handled:
-///
-/// ## [`QuantizedTensor<B>`]
-/// If the method returns a `QuantizedTensor<B>`, the operation is expected to preserve the quantized
-/// representation. Implementations should avoid dequantizing when possible to maintain performance.
-/// For example, shape or layout changes such as expand or transpose preserve quantization.
-///
-/// *Note: while this currently doesn't affect the quantized tensor parameters (only per-tensor is
-/// supported at the time of writing), other quantization levels (e.g., per-block) may require re-ordering
-/// the quantization parameters to match the new layout.*
-///
-///
-/// ## [`TensorPrimitive<B>`]
-/// If the method returns a `TensorPrimitive<B>` enum, the return type should align with propagation
-/// strategy specified in the quantization scheme. The output should remain quantized ([`TensorPrimitive::QFloat`])
-/// returned in floating-point form ([`TensorPrimitive::Float`]).
-///
-/// This distinction allows for fine-grained control over mixed-precision flows while still operating
-/// through a unified API.

-/// Slice argument constructor for tensor indexing.
-///
-/// The `s![]` macro is used to create multi-dimensional slice specifications for tensors.
-/// It converts various range syntax forms into a `&[Slice]` that can be used with
-/// `tensor.slice()` and `tensor.slice_assign()` operations.
-///
-/// # Syntax Overview
-///
-/// ## Basic Forms
-///
-/// * **`s![index]`** - Index a single element (produces a subview with that axis removed)
-/// * **`s![range]`** - Slice a range of elements
-/// * **`s![range;step]`** - Slice a range with a custom step
-/// * **`s![dim1, dim2, ...]`** - Multiple dimensions, each can be any of the above forms
-///
-/// ## Range Types
-///
-/// All standard Rust range types are supported:
-/// * **`a..b`** - From `a` (inclusive) to `b` (exclusive)
-/// * **`a..=b`** - From `a` to `b` (both inclusive)
-/// * **`a..`** - From `a` to the end
-/// * **`..b`** - From the beginning to `b` (exclusive)
-/// * **`..=b`** - From the beginning to `b` (inclusive)
-/// * **`..`** - The full range (all elements)
-///
-/// ## Negative Indices
-///
-/// Negative indices count from the end of the axis:
-/// * **`-1`** refers to the last element
-/// * **`-2`** refers to the second-to-last element
-/// * And so on...
-///
-/// This works in all range forms: `s![-3..-1]`, `s![-2..]`, `s![..-1]`
-///
-/// ## Step Syntax
-///
-/// Steps control the stride between selected elements:
-/// * **`;step`** after a range specifies the step
-/// * **Positive steps** select every nth element going forward
-/// * **Negative steps** select every nth element going backward
-/// * Default step is `1` when not specified
-/// * Step cannot be `0`
-///
-/// ### Negative Step Behavior
-///
-/// With negative steps, the range bounds still specify *which* elements to include,
-/// but the traversal order is reversed:
-///
-/// * `s![0..5;-1]` selects indices `[4, 3, 2, 1, 0]` (not `[0, 1, 2, 3, 4]`)
-/// * `s![2..8;-2]` selects indices `[7, 5, 3]` (starting from 7, going backward by 2)
-/// * `s![..;-1]` reverses the entire axis
-///
-/// This matches the semantics of NumPy and the ndarray crate.
-///
-/// # Examples
-///
-/// ## Basic Slicing
-///
-/// ```rust,ignore
-/// use burn_tensor::{Tensor, s};
-///
-/// # fn example<B: Backend>(tensor: Tensor<B, 3>) {
-/// // Select rows 0-5 (exclusive)
-/// let subset = tensor.slice(s![0..5, .., ..]);
-///
-/// // Select the last row
-/// let last_row = tensor.slice(s![-1, .., ..]);
-///
-/// // Select columns 2, 3, 4
-/// let cols = tensor.slice(s![.., 2..5, ..]);
-///
-/// // Select a single element at position [1, 2, 3]
-/// let element = tensor.slice(s![1, 2, 3]);
-/// # }
-/// ```
-///
-/// ## Slicing with Steps
-///
-/// ```rust,ignore
-/// use burn_tensor::{Tensor, s};
-///
-/// # fn example<B: Backend>(tensor: Tensor<B, 2>) {
-/// // Select every 2nd row
-/// let even_rows = tensor.slice(s![0..10;2, ..]);
-///
-/// // Select every 3rd column
-/// let cols = tensor.slice(s![.., 0..9;3]);
-///
-/// // Select every 2nd element in reverse order
-/// let reversed_even = tensor.slice(s![10..0;-2, ..]);
-/// # }
-/// ```
-///
-/// ## Reversing Dimensions
-///
-/// ```rust,ignore
-/// use burn_tensor::{Tensor, s};
-///
-/// # fn example<B: Backend>(tensor: Tensor<B, 2>) {
-/// // Reverse the first dimension
-/// let reversed = tensor.slice(s![..;-1, ..]);
-///
-/// // Reverse both dimensions
-/// let fully_reversed = tensor.slice(s![..;-1, ..;-1]);
-///
-/// // Reverse a specific range
-/// let range_reversed = tensor.slice(s![2..8;-1, ..]);
-/// # }
-/// ```
-///
-/// ## Complex Multi-dimensional Slicing
-///
-/// ```rust,ignore
-/// use burn_tensor::{Tensor, s};
-///
-/// # fn example<B: Backend>(tensor: Tensor<B, 4>) {
-/// // Mix of different slice types
-/// let complex = tensor.slice(s![
-///     0..10;2,    // Every 2nd element from 0 to 10
-///     ..,         // All elements in dimension 1
-///     5..15;-3,   // Every 3rd element from 14 down to 5
-///     -1          // Last element in dimension 3
-/// ]);
-///
-/// // Using inclusive ranges
-/// let inclusive = tensor.slice(s![2..=5, 1..=3, .., ..]);
-///
-/// // Negative indices with steps
-/// let from_end = tensor.slice(s![-5..-1;2, .., .., ..]);
-/// # }
-/// ```
-///
-/// ## Slice Assignment
-///
-/// ```rust,ignore
-/// use burn_tensor::{Tensor, s};
-///
-/// # fn example<B: Backend>(tensor: Tensor<B, 2>, values: Tensor<B, 2>) {
-/// // Assign to every 2nd row
-/// let tensor = tensor.slice_assign(s![0..10;2, ..], values);
-///
-/// // Assign to a reversed slice
-/// let tensor = tensor.slice_assign(s![..;-1, 0..5], values);
-/// # }
-/// ```

-/// A slice specification for a single tensor dimension.
-///
-/// This struct represents a range with an optional step, used for advanced indexing
-/// operations on tensors. It is typically created using the [`s!`] macro rather than
-/// constructed directly.
-///
-/// # Fields
-///
-/// * `start` - The starting index (inclusive). Negative values count from the end.
-/// * `end` - The ending index (exclusive). `None` means to the end of the dimension.
-/// * `step` - The stride between elements. Must be non-zero.
-///
-/// # Index Interpretation
-///
-/// - **Positive indices**: Count from the beginning (0-based)
-/// - **Negative indices**: Count from the end (-1 is the last element)
-/// - **Bounds checking**: Indices are clamped to valid ranges
-///
-/// # Step Behavior
-///
-/// - **Positive step**: Traverse forward through the range
-/// - **Negative step**: Traverse backward through the range
-/// - **Step size**: Determines how many elements to skip
-///
-/// # Examples
