xPRIMEray — Specification Index

This index aligns the spec set to the current MkDocs navigation and makes every Markdown document in the /Docs tree reachable from either this page or the top-level Home page.

Supporting architecture and validation docs

These are not spec files, but they are tightly coupled to the spec set and should remain visible in MkDocs.

• System Architecture
• Architecture Overview
• Architecture Review
• Code Map (Big 12)
• Validation Framework
• BoundaryLayerVolume Fixture Specification Minimal deterministic fixtures for validating boundary crossing behavior, policies, and nested shell ordering → BoundaryLayerFixtures.md
• Metric Null Geodesic Parameter Map
• Next-Generation Metric Transport Roadmap
• BlackHole Fast Compare (GRIN vs Metric)
• Property Surface
• RenderStep Gate Hierarchy Snapshot

Alignment notes

• MkDocs should use docs_dir: Docs because the repository folder is capitalized.
• The _1 spec files are treated as the active revised documents.
• The non-_1 spec files are retained as legacy baselines and intentionally kept linked.
• The top-level Home page and this page together provide link coverage for all .md files currently present in /Docs.
