v1.0.0 - Curated Redtail snapshot with technical documentation

First tagged release of this repository: a curated, integrity-verified snapshot of the NVIDIA Redtail autonomous visual-navigation stack (TrailNet + TensorRT + ROS + PX4), documented for study and for maintenance on modern Jetson platforms.

Highlights

• Technical documentation suite (docs/) with Mermaid diagrams:
  • Architecture - perception-control dataflow, TrailNet 6-class head semantics, OFFBOARD control-loop sequence, TensorRT engine pipeline, stereo pipeline, codebase composition
  • ROS package reference - every node's topics, message types, and parameters, verified against source
  • Jetson AGX Xavier guide - TX1/TX2 to Xavier platform delta and an 8-step porting checklist backing the agx-xavier branch
  • Model inventory - SHA-256 checksums and sizes for all TrailNet, YOLO, and stereo DNN artifacts
• Governance: CHANGELOG.md (Keep-a-Changelog), CITATION.cff (snapshot + IROS 2017 / CVPR-W 2018 papers), CONTRIBUTING.md (branch policy: main stays a faithful snapshot; platform work lands on agx-xavier/jetson-nano-2gb/ros_isaac)
• Metadata fixes: px4_controller package description/version corrected; on-device installer now clones this repository instead of the retired NVIDIA-Jetson/redtail URL

Provenance and scope

The imported C++/CUDA/Python sources, models, launch files, and platform assets remain byte-identical to the final upstream NVIDIA-AI-IOT/redtail tree (BSD-3-Clause, NVIDIA copyright preserved). This release adds documentation and metadata only.

Compatibility warning

Legacy research software targeting Ubuntu 16.04 / ROS Kinetic / CUDA 9 / TensorRT 3-4 / Jetson TX1-TX2. Not safety-certified; not suitable for operational autonomous flight without independent validation. See README Safety and Limitations.
