## Source type

User-supplied Markdown report preserved as local project source material. It is not treated as a peer-reviewed paper, a deployment incident, or proof that any described scenario is currently occurring.

## What this report contributes

The shift from cloud to on-device AI is driven by privacy and latency needs. On-device LLMs reduce response time and keep data local, but are constrained by limited CPU/GPU power, memory and energy. Tiny language models (tens to a few hundreds of millions of parameters) and aggressive model compression (quantization, distillation, pruning) are key to fitting LLMs on client devices. For example, quantizing a 117M-parameter GPT-2 model from 32-bit to 8- or 4-bit can shrink its memory footprint from ~500 MB to ~150 MB. Similarly, distilled or parameter-efficient variants (like DistilGPT-2 or LoRA-adapted models) trade a small accuracy loss for major reductions in size and compute.

## Site interpretation

The report is used to expand Cognivirus.com as a critical, evidence-bound observatory. Its strongest contribution is scenario language for understanding why small interchangeable components, LoRA adapters, model breeding, code beading, human incentives, frugal deployment, and teleodynamic selection can become governance problems when they are coupled into a transition graph.

## Publication boundary

The public site should cite this as a source dossier, not as established empirical evidence. Operational replication, evasion, social manipulation, steganography, backdoor construction, exploit, or autonomous-spread instructions must not be reproduced in public-facing pages. Safe content may be paraphrased into risk analysis, control design, and evidence-maturity guidance.
