Signed-to-Unsigned Tensor Offset Wraparound in stable-diffusion.cpp
How a signed 32-bit storage_offset in a PyTorch ZIP archive sign-extended to 64-bit unsigned arithmetic, wrapped offset + nbytes past the bounds check in stable-diffusion.cpp (CVE-2026-115571 / GHSA-cfhc-rw9j-rp26), and how sibling arithmetic and duplicate-key bugs surfaced across SafeTensors, GGUF, and imatrix loaders (CVE-2026-70659).

Static Spectral Trojan Auditing and Pre-Load Checkpoint Sanitization
How trust boundaries, C++/CUDA kernel failure classes, and spectral weight audits fit together, with measurements from a 46-file local inventory (2,619 analyzed weight matrices across 14 full-model reads and 16 scoped variants) and 186.8M GGUF quantized blocks.

Project-Then-Heal: Weight-Space Programming and Subspace-Locked LoRA
How weight edits map to SafeTensors and GGUF storage, why head permutations matter, and what live fine-tuning and synthetic tests show about subspace-locked LoRA.
