Subject: [PATCH] Add LLM fine-tuning pipeline and F1 halo removal projects

- LLM fine-tuning & on-device inference pipeline: LoRA fine-tuned Llama 3.2
  3B, GGUF quantization, llama.cpp evaluation on 106-case held-out set.
  Results: +0.192 recall over generic baseline at ~half the latency. Domain
  intentionally omitted.
- F1 Halo Removal (CSCI 365 final): classical CV mask detection (Sobel-Y
  arch, probe-and-fit keel) + LaMa spatial inpainting vs RAFT temporal
  propagation on 300-frame 60fps visor-cam footage.

Used LoRA adapters on Llama 3.2 3B via MLX (Apple Silicon) and evaluated across four artifacts: generic F16, generic Q4_K_M, fine-tuned F16, and fine-tuned Q4_K_M. The deployable artifact — fine-tuned Q4_K_M GGUF — achieved 0.961 recall and 100% JSON validity at 2.91s average latency on llama.cpp, compared to 0.780 recall and 6.65s for the generic F16 baseline. Quantization after fine-tuning cost only 0.011 recall while cutting latency in half. Evaluation ran on a 106-case held-out set with automated recall, JSON validity, and schema validity scoring.",

+      "The Halo is a mandatory titanium arch on all F1 cars. It saves lives but cuts through the most interesting part of onboard footage. This project removes it cleanly from visor-cam video using two stages. Stage one: classical CV mask detection — Sobel-Y gradient detection for the arch edge, a robust probe-and-fit keel detector with outlier rejection and temporal jump guards, and explicit geometry construction to avoid over-masking. Stage two: two inpainting methods compared side by side — LaMa (Fast Fourier Convolution network, per-frame spatial inpainting) and RAFT optical flow with backward warp and distance-transform blending for temporal coherence across 300 frames at 60fps.",
