Project ATO 1.0 — Digital Engineering Release

Project ATO gives a future invasive spinal interface a scientific argument and
an editable digital engineering identity. This first release is entirely digital.

• 20-page illustrated engineering paper: spinal evidence, architecture,
  mathematics, generated results, design decisions and remaining questions.
• Two reproducible synthetic studies: expert-informed rhythmic practice and
  physiological pressure feedback, with negative controls, sensitivity analysis
  and published raw results.
• Electronics and timing: native routed KiCad project, BOM, manufacturing
  reference exports, analytical and generic-device SPICE models, and portable
  C pulse logic connected to the application traces.
• Mechanical and visual design: parametric solids, STEP/STL, native FreeCAD
  assembly, editable Blender scenes and rendered views.
• Presentation: local interactive walkthrough, learning guide and a
  72-second captioned video.

Local verification passed 14 Python tests, 23 compiled-C assertions, seven adapter
checks, clean ERC/DRC/parity checks and nominal CAD intersection checks. The
GitHub Actions run also successfully verified artifact hashes, regenerated both
studies, compiled and exercised the C module, and passed the tests and release
checks on Linux with Python 3.12.

· Verification record
· Successful automated run

Download the attached paper and video, or the full ZIP snapshot for all source
and native design files. SHA256SUMS.txt records the downloadable file hashes.
The repository and release remain private.

Numerical improvements are conditional model results. No human or animal signals
were recorded, no hardware was fabricated, and no implant effectiveness or
clinical safety is established. External acquisition/sequencing and a biological
interface are outside the reference circuit's implementation. Research claims,
AI contributions and third-party credits are disclosed. AstroSam's Mind-Link
inspired the project format; ATO develops its own spinal concept and files.
