v1.0.6 — Lykuro Native Inference Engine (pre-release)

v1.0.6 (2026-08-15)

First-request latency and download integrity

• Model load 16.9s → 3.0s for Qwen2.5-1.5B on an M4 Pro (43.9s → ~18s on a Linux/CUDA host without SHA-NI): the CPU reference build and its CPU smoke forward are skipped when a GPU backend serves (the backend's own pre-warm is the smoke inference), Metal/CUDA weight conversion + quantization + upload runs on a thread pool, and the in-tree SHA-256 gains hardware compression (ARMv8 SHA2 / x86 SHA-NI with runtime dispatch) for multi-GB artifact digest verification. LYKURO_LOAD_PROF=1 prints the load-phase breakdown.
• pull verifies downloads against the upstream SHA-256 (Hugging Face's x-linked-etag, the LFS object hash) before conversion. A silently corrupted download previously produced an artifact that generated garbage yet passed every load-time check — the artifact's own checksums are derived from the downloaded bytes. A mismatch now fails the pull loudly.

See docs/RELEASE_NOTES.md for full notes. Same pre-release caveats as v1.0.0 (unsigned macOS binaries pending Developer ID enrollment).

Runtime requirements: Linux binaries need glibc + system OpenSSL (CUDA package additionally needs the NVIDIA driver/CUDA runtime); macOS binaries need Apple Silicon (arm64) and are ad-hoc signed — browser downloads need xattr -d com.apple.quarantine once.
