Weights: Baekpica/GLM-5.3-Flash-VQ-GGUF @ 4da527cd0f9e83ccd9fb451a1feaf3ba861f7c77 (GVQ1 Q4_K nonexpert v3; 56 parts + tables verified via HF API this ingest; SHA256SUMS verified by the engine at load per runbook). Engine: Baekpica/ds4-dfm-rs (Rust host of antirez/ds4), main from c5384b5e PR86; measured on optimize4 checkout.
