llama.cpp prereleases sanitize tool-call bytes and align precision paths
Signed prerelease b12199 sanitizes invalid UTF-8 before PEG-parsed tool-call arguments reach downstream agents. Later b12202 aligns BF16 and F32 accumulation choices with reference implementations for GLM4, MiMoVL, Qwen3-TTS, DeepSeek V4 and MiniMax-M3 paths and adds BF16 flash-attention tests.
Why it matters: Malformed tool-call arguments can break structured parsers or terminate an agent loop, while unintended accumulation precision can change model behavior or hardware fallback. The builds create exact artifacts for testing both boundaries.
