Module absolute_position 

Absolute position embeddings kernel.

Matches absolute-position-v1.yaml. output[t] = token_embed[t] + pos_embed[t] — learned additive positional encoding.

Each function provides one of three backends:

• fn abs_position_scalar(...) – Pure Rust scalar reference (ground truth)
• unsafe fn abs_position_avx2(...) – AVX2 SIMD implementation
• fn abs_position_ptx() -> &'static str – PTX assembly source string

Functions

abs_position_avx2^⚠

AVX2 absolute position embeddings – delegates to scalar.

abs_position_ptx

PTX assembly for absolute position embeddings.

abs_position_scalar

Add learned position embeddings to token embeddings (scalar reference).
