ViperEkura 4f2e03880b fix : repair and extend throughput benchmark 
- adapt bind_tasks to workspace API and reuse a stable workspace
- drop required checkpoint, randomize default 1B GQA preset
- add config override flag for arbitrary model architectures

ViperEkura 8152760b5f refactor : use factory for attention backends 
- register built-in backends through BaseFactory

ViperEkura 8447f88f61 fix: size KV pool from prompt/gen args in benchmark 
- Drop hardcoded CACHE_MAX_SEQ=2048 which overflowed at long prompts
- Size prefill pool to prompt_length and decode pool to prompt+5+gen*num_trials
- Unblocks decode/prefill benchmark at prompt 4096+ (was KV cache index OOB)

ViperEkura 41dcf0feb9 feat: SGLang-style paged attention kernels replace page-table path 
- PagedAttentionParams uses flat KV pool + req_to_token + kv_indptr/qo_indptr instead of page_table
- MMA split-KV decode and split-Q prefill kernels with indirect ragged-batch addressing
- Prefill kernel accepts 4D mask (causal-aware); decode kernel supports 2D mask
- CudaBackend is inference-only: kv_cache=None raises, no torch fallback
- benchmark.py: required --ckpt, --backend/--compare options
- Parallel build isolates build-temp/build-lib per subprocess
- Standalone test covers decode/prefill with mask, 27 cases pass

ViperEkura 07625057f2 feat : add setup_logging with hierarchical astrai logger 
- setup_logging(): attach handler only to astrai logger, not root
- all astrai.* sub-module loggers inherit automatically
- controlled by ASTR_LOG_LEVEL env var (default INFO)
- called in if __name__ == '__main__' of each CLI script

- dim_ffn -> intermediate_size, n_heads -> num_attention_heads
- n_kv_heads -> num_key_value_heads, max_len -> max_position_embeddings
- norm_eps -> rms_norm_eps, tie_weight -> tie_word_embeddings
- update model, inference, training, scripts, tests, docs

ViperEkura f0cd0134c6 fix : update benchmark for v1.3.8 cache API, add argparse and cache type switch 
- Replaced old KVCage API with PageCache/ContiguousCache
- Added --cache contiguous|paged switch for decoding comparison
- Added argparse for all params (batch/prompt/gen/device/dtype)
- Fixed PageCache decode crash by extending pages for full sequence

- process_attention_mask 用 position_ids >= arange 做逐位置 causal

- 训练/无 KV cache 时 position_ids=None 内部自动处理

- 移除 executor/benchmark 中冗余的 input_mask 构造
