Custom C++20 PID 1 init supervisor, userspace ecosystem, and minimal bootable Linux distribution.

• Supervisor Core: Custom PID 1 init supervisor replacing SysV/systemd, executing virtual filesystem mounts (/proc, /sys, /dev, /dev/pts, /run), network socket ioctl(SIOCSIFADDR) interface bring-up (lo, eth0), and asynchronous SIGCHLD zombie process reaping.
• Dependency Ordering: Declarative unit file parser (/etc/freedot.d/) executing Directed Acyclic Graph (DAG) topological sort for strict startup sequencing.
• Daemon IPC: Bidirectional UNIX domain socket IPC server (/run/freedot.sock) with a dedicated freedotctl command-line utility for runtime daemon queries and lifecycle signals.
• Minimal Footprint: Boots upstream Linux LTS kernel (bzImage) into a custom 3.9 MB initramfs cpio rootfs in QEMU/KVM with near-instant bootstrap.
• Status: | Repository

Touchless Rubik's Cube timer utility driven by real-time computer vision heuristics.

• Gesture Pipeline: Google MediaPipe HandLandmarker tracking 21 3D landmarks per hand at low inference latency.
• Spatial Geometry: Euclidean distance vectors comparing fingertip-to-wrist against knuckle-to-wrist ratios with a 30% margin threshold across primary digits for posture detection.
• State Filtering: Temporal trajectory state machine requiring 4 directional inflection reversals to reject spurious motions during timer reset.
• Color Verification: HSV color space ROI segmentation analyzing mean saturation and hue standard deviation to confirm solved cube face alignment.
