# Reproducible Global Report: Fibonacci Alpha Chambers

## Overview

RU is a certificate engine for universality and obstructions in constrained nonnegative propagation. Host structures supply finite inputs. Outputs are audited certificates or finite obstruction witnesses.

## How it is generated

From the root:

- Generate the two prerequisite audited certificates:
  - `python tools/ru_bridge_extractor.py --example fibonacci_contraction --alpha 0.2 --validate`
  - `python tools/ru_bridge_extractor.py --example fibonacci_og4_idle --validate`

- Build the chamberwise global report:
  - `python tools/build_fibonacci_alpha_chambers_report.py`

## Output

- `sources/ru/global_universality_report_fibonacci_alpha_chambers.json`

## Why this matters

This shows the difference between:

- claiming “global universality,” and
- providing a global report object that explicitly:
  - states the parameter region
  - classifies chambers
  - records which certificate objects support each chamber
  - records the boundary obstruction witness

This is the “global” part of the RU program expressed as a finite auditable artifact.
