ViperEkura da6d94492d fix: parse yaml floats with yaml 1.2 schema
- register yaml 1.2 float resolver so scientific notation (2e-5) becomes float, not str
- replaces the decimal-point workaround in train configs
- add containerized training doc under docs/developer

- fix CudaBackend fallback chain description (FlashAttn → TorchNative)
- add FlashAttnBackend to architecture strategy table

ViperEkura 2667b8116d refactor: unify paged and contiguous attention kernels via KVSource policy
- merge AttentionParams and PagedAttentionParams into one struct
- add attn_kv_source.cuh with ContigKV/PagedKV addressing policies
- template prefill/decode kernels (MMA + scalar) on the KV policy, deleting the four duplicated attn_paged_*.cuh variants
- template dispatcher launchers on KV; single combine kernel
- verify: all correctness tests pass and SASS matches baseline (no perf regression)

ViperEkura 49a9c6b3d2 build: migrate CUDA kernel build to CMake
Replace torch CUDAExtension/ParallelBuildExtension with a CMake-based build. Each kernel compiles as an independent pybind11 module in parallel via cmake --build -j, outputting to astrai/extension/lib.

- Add csrc/CMakeLists.txt (5 kernel targets, torch/pybind11 linking)
- setup.py: _CMakeBuildExt invokes cmake; auto-detect CUDA arch via torch
- Remove csrc/build.py (REGISTRY/build flags now in CMakeLists)
- Fix rel-err eps in attn_test.cu (1e-8 -> 1e-4, bf16 scale)
- Update docs/developer/cuda_kernels.md build section
- .gitignore: allow csrc/CMakeLists.txt

ViperEkura cdf9145ecf docs: align CUDA kernel and RoPE docs with code
- Fix rotary docs to describe cos/sin freqs_cis table, not complex buffer
- Replace attn_prefill with attn_paged_prefill for the CudaBackend path
- Register attn_paged_prefill in kernel overview, layout, and module list
- Add qo_indptr and InferenceWorkspace to architecture class diagram
- Add FrequencyPenaltyStrategy to sampling design patterns

ViperEkura 3439e3104e perf: launch CUDA kernels on torch's current stream
- Thread a cudaStream_t through attn dispatchers onto torch's current stream
- Scope the device guard to the entry function so kernels run on tensor device
- DISPATCH_HEAD_DIM now forwards varargs so stream reaches each dispatch
- Parallelize CPU reference kernels with OpenMP (paged test 31s -> 7s)
- Merge decode/prefill standalone tests into attn_test.cu with correctness tables
- Drop bench error column (CPU ref too slow at large sizes)
- Update cuda_kernels.md for the merged test layout

ViperEkura 288ba20db1 docs: audit non-CUDA documentation
- Aligns CLI and strategy metric contracts
- Refreshes architecture, dataflow, preprocessing, distributed, and eval guides
- Corrects links, TOCs, defaults, and repository paths

ViperEkura 1c7369f293 feat: add MoE auxiliary loss metrics
- Propagates MoE load-balancing loss through model outputs
- Logs task, auxiliary, and weighted losses across strategies
- Computes only explicitly requested callback metrics
- Preserves tensor compute_loss API and adds regression tests

ViperEkura 7aa5ed09d9 refactor: unify rotary embedding interface and update docs
- Merge cos/sin into single freqs_cis tensor [batch, seq, dim/2, 2] throughout the pipeline: RotaryEmbedding buffer, forward return type, apply_rotary_emb signature, CUDA kernel interface
- CUDA kernel now takes freqs_cis directly and reads cos/sin via stride offset internally, eliminating Python-side slice/copy overhead
- Kernel interface: rotary_emb(x, freqs_cis) replaces rotary_emb(x, cos, sin)
- All call sites pass rotary_emb as Tensor (was tuple), type annotations consistent
- Update build threads from 8 to 16
- Fix all docs: get-started, inference, training, cuda_kernels, architecture, internals — reflect new rotary interface, KVCache fields, rotary backend dispatch, .so path, kernel registry count, file layout

- Remove stale 'not yet wired' references
- Add AttentionBackend/CudaBackend sections to cuda_kernels.md, internals.md, inference.md
- Add astrai.extension to architecture.md module table and design patterns
- Update get-started.md: CUDA kernels activatable via attn_backend()

ViperEkura df979b4469 refactor: use single-index access and update docs for cache architecture
- Replace all buffer[layer_id][loc] double indexing with buffer[layer_id, loc] single advanced indexing in cache.py and attention.py
- Revert KVStorage buffers back to 4D [n_layers, size, n_kv_heads, head_dim], remove leftover 3D reshape/view in MLA path
- Update docs/guides/inference.md, docs/developer/internals.md, docs/developer/architecture.md to reflect new PagePool/KVStorage/ReqToTokenPool/KVCache classes

- Add guides/evaluation.md: 7 eval scripts with CLI args
- Add guides/distributed.md: DDP/FSDP, gradient accumulation, NCCL
- Add developer/internals.md: loss formulas, RoPE, KV cache math
- Add developer/cuda_kernels.md: build system, benchmarks, file layout
- Fix storage_format doc in preprocessing.md
- Update cross-references in README.md, README-zh-CN.md, Dockerfile
