refactor(hpc): add simd_caps LazyLock singleton — detect once, dispat…#34
Merged
Conversation
…ch forever Replace 38 per-call is_x86_feature_detected! macro invocations across 10 HPC modules with a single LazyLock<SimdCaps> singleton. Each macro call was a hidden AtomicU8 load (~3ns); now it's one LazyLock deref to a frozen Copy struct (~1ns). New module: simd_caps.rs - SimdCaps: Copy struct with avx2/avx512f/avx512bw/avx512vl/ avx512vpopcntdq/sse41/sse2/fma fields - simd_caps(): inline(always) accessor via static LazyLock - has_avx512_popcnt(), has_avx512_bw_popcnt() convenience methods - 4 tests (detect, Copy, deterministic, convenience) Swept files: aabb, bitwise, byte_scan, cam_pq, distance, nibble, palette_codec, property_mask, spatial_hash (production code only; test guards left as-is). 1135 HPC tests pass, 0 failures. https://claude.ai/code/session_01CdqyUTUfjKZuk8YGJzv6LB

12 cognitive primitives implemented: 7 as styles/ submodules (rte, htd, smad, tcp, irs, mcp, tca) 5 as additions to existing modules (causal_diff, bgz17_bridge, nars, cascade) 21 tests passing. Waiting for tactics #13-#34. https://claude.ai/code/session_01M3at4EuHVvQ8S95mSnKgtK
