From 92e931962373cf1f5d03729c0ff1a281a1db5257 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 22 Feb 2026 15:43:27 +0000 Subject: [PATCH 01/18] Implement Pyraview C Engine with Python/Matlab Wrappers Implements high-performance C-based decimation engine using OpenMP. Includes Python wrapper (ctypes) and Matlab MEX gateway. Safety features: Header validation, mismatch prevention, resource cleanup.
