This report documents the empirical evaluation underlying SLMGen. We analyze LoRA rank sensitivity, 4-bit NormalFloat (NF4) quantization degradation, and dataset token hygiene heuristics across Phi-3.5, Llama-3.2, and Qwen-2.5 base models.

We present the design of Veda, a high-performance Rust parallel execution runtime implementing an adaptive work-stealing algorithm with NUMA node affinity pinning. Empirical benchmarks on 32-core and 64-core topologies demonstrate up to a 2.4x reduction in task dispatch latency compared to naive work-stealing.

We investigate the failure modes of ambient shell execution in language model agents, analyze process isolation mechanisms across Linux cgroups v2 and macOS Seatbelt, and benchmark a two-phase SQLite WAL crash-recovery architecture capable of restoring consistent workspace states following abnormal process termination.

We define the problem space separating conversational assistants from sovereign execution runtimes, formalize an 11-stage non-bypassable policy gating model, and introduce empirical verification criteria where language model assertions are treated as untrusted until mathematically and observationally proven.
