== 1.0 Abstract ==
This document outlines the build plan for the Minimum Viable Reality, Version 1 Toroidal Extension (MVR-1-T), an evolution of the MVR-1 interferometer designed as a closed-loop, triangular toroidal optical network. The MVR-1-T comprises three straight, ferrofluid-filled tubes forming an equilateral triangle, with three nodes hosting lasers and servo-driven mirrors for sequential SL-PPM signal propagation. It serves as a '''physics co-processor''' for the '''AetherOS''' simulation environment, generating non-deterministic interference patterns as ground-truth data for '''FluxCore''' AI training. This design leverages MVR-1 components for economy and supports scalability to 3D geometries (e.g., tetrahedron, tesseract).

== 2.0 System Architecture ==

=== 2.1 Conceptual Model ===
The MVR-1-T extends the MVR-1’s one-dimensional interferometer into a closed-loop, triangular toroidal configuration. Instead of a single straight tube, three tubes form a polygonal toroid, with nodes directing counter-propagating SL-PPM laser beams to create complex interference patterns modulated by magnetic fields. This setup mimics continuous toroidal propagation while avoiding high bending losses, enabling multi-pass interactions for enhanced data generation.

The workflow mirrors the MVR-1:
# AetherOS requests the state of a virtual network link.
# It sends input parameters (laser modulation, mirror position, magnetic field) to the MVR-1-T controller.
# The system executes the state, with servo mirrors selecting the active tube.
# Interference patterns and magnetic field data are read from sensor arrays.
# High-fidelity physical data is returned to AetherOS as ground truth.

=== 2.2 Physical Overview ===
The MVR-1-T is an optical bench assembly on a rigid base, forming an equilateral triangle (side ~170-200 mm).
* '''The Base:''' A flat ABS plastic sheet (~12" x 12") for stability.
* '''The Housing:''' 3D-printed PETG enclosures for three tubes and three nodes, shielding from ambient light.
* '''The Spokes (Tube Assemblies):''' Three borosilicate glass tubes with flexible PCBs, identical to MVR-1’s Spoke.
* '''The Nodes:''' Three hubs, each with a 520 nm laser, servo-driven mirror, photodiode, and magnetic sensors.
* '''The Controller:''' One or three Raspberry Pi Picos managing laser modulation, mirror positioning, magnetic actuation, and sensor readout.

== 3.0 Component Breakdown ==

* '''Sensors:''' Single photodiode (e.g., Thorlabs FDS100) per node for interference detection, plus Hall sensors for local field monitoring.
* '''Mount:''' 3D-printed kinematic mount for laser and mirror alignment (pan/tilt adjustment).
* '''Control:''' Raspberry Pi Pico (or shared) for SL-PPM modulation, servo control, and sensor readout.

== 5.0 Operation ==
The MVR-1-T operates as a closed-loop interferometer:
# AetherOS sends parameters (e.g., SL-PPM pulse patterns, magnetic field strength) to the Pico(s).
# Each node’s servo mirror selects a tube (e.g., Node 1 to Tube 1 or Tube 3).
# Counter-propagating 520 nm SL-PPM beams (e.g., from Node 1 and Node 2 into Tube 1) create interference patterns in the ferrofluid, modulated by the double helix magnetic field.
# Photodiodes capture scattered light, and Hall sensors measure the field, providing non-deterministic data.
# Data is sent to AetherOS via USB serial for FluxCore training.

== 6.0 Scalability Path ==
The MVR-1-T is a direct bridge to complex geometries:
* '''Phase 1: MVR-1 (Single Tube):''' Completed as baseline interferometer.<ref name="MVR1">{{cite document |title=Project Aether: MVR-1 Build Plan}}</ref>
* '''Phase 1.5: MVR-1-T (Triangle):''' This build, testing closed-loop toroidal propagation with 3 nodes, 3 tubes.
* '''Phase 2: Tetrahedron (4 Nodes, 6 Tubes):''' Add 1 node ($85-$185) and 3 tubes ($100-$200). Reprogram servos for 3-position steering. Total cost: ~$750-$1,650.
