# step 30 — engine Index and Final Acceptance Checklist

## Purpose


## example audited artifact (concrete)

This engine now includes a fully instantiated, mechanically auditable bridge artifact:

- `docs/Example_Fibonacci_Minimal.md`

It ships a complete host instance plus an RU robust certificate (`sources/ru/robust_certificate_fibonacci_fusion.json`) and a bridge wrapper (`sources/ru_bridge/bridge_certificate_fibonacci_fusion.json`).



This final step makes the engine usable as a single coherent artifact.

It provides:

- a navigation index
- the acceptance checklist for maximal-level universality claims in this engine

## Navigation

- `docs/StringTheory_Index.md` (keyword map over sources/context/string_theory.pdf)


- `docs/Host_Input_Guide.md` (how to build a host instance)


- `docs/Theorem_Files.md` (file list)


- `docs/Theorem_Linkage.md` (theorem sources and certificate mapping)


- `docs/Global_Report_Fibonacci_Alpha.md` (reproducible chamberwise global report)


- `docs/RU_Engine_Overview.md` (paper-style synthesis entry point)

## Acceptance checklist for maximal-level claims

A claim in this engine qualifies as maximal-level universality only if:

- A reduction to an RU instance is stated (graph, templates, costs, constraints).
- A robust RU certificate is present (or explicitly stated as absent with an obstruction witness).
- If claiming region-wide validity: a global universality report covers the parameter region.
- All scope constraints are stated (sector restriction, truncations, metric, bounds).
- Every strong conclusion is either:
  - supported by a certificate object, or
  - weakened to a lower-tier statement with explicit uncertainty.

## Files that carry proof weight

- `sources/ru/robust_certificate_schema.json`
- `sources/ru/global_universality_report_schema.json`
- and any instance files satisfying them

Universality claims live in audit objects, not in rhetoric.
