Concepts

These pages explain the system contracts that exist in VyDex today. They are written for technical users, maintainers, and coding agents that need enough context to change the implementation without breaking its boundaries.

The navigation follows VyDex's dependency and publication flow: application foundation, evidence records, release construction, public presentation, and hosted verification.

System Map

• Static Application Foundation — Static Astro build, domain separation, Schema publication, and test boundaries.
• Evidence Ledger — Versioned canonical Entry contracts, immutable publication revisions, validation, and v1/v2 history boundaries.
• Release Lifecycle — Resolved release construction, current Dataset 2.0.0 generation, preserved Dataset 1.0.0 compatibility, and repeatable publication.
• Public Interface — Entry v2 pages, versioned Methodology routes, Dataset 2.0.0 export surfaces, and the shared presentation contracts readers use to inspect the ledger.
• Deployment And Verification — Cloudflare Pages publication, hosted checks, rollback evidence, and restoration boundaries.

Concept pages describe current behavior and ownership. Step-by-step user workflows belong in Guides, and planned capabilities remain identified as future work until their implementation exists.
