What is hosted here
This page, its dedicated Lean module, its source coordinate, and its place in the complete ecosystem directory are published together. It is not merely a row hidden inside a registry.
What Lean checks
The dedicated module elaborates an Entry that resolves directly to the canonical registry definition. The release gate also requires this page, its generated Lean page, and its manifest record to agree.
Source boundary
This is an explicitly registered local candidate. The portal does not invent a public repository or source pin for it. Source provenance establishes what was inspected; it does not establish the truth of every external claim.
Semantic boundary
The current explanation remains visibly unreviewed by Tyler. Compilation cannot silently promote source-derived prose to owner-reviewed doctrine.
