Build and maintain a company knowledge base as a wiki of interlinked markdown notes in the workspace — a private, compounding Wikipedia. Use when the user wants to start or organize a knowledge base / wiki, ingest sources (URLs, documents, pasted notes) into it, ask questions answered from it, or audit (lint) it. Defines the wiki layout (SCHEMA / index / log / raw / pages), the frontmatter contract, [[wikilink]] conventions, and a deterministic lint script that catches broken links, orphan pages, index drift, and frontmatter problems.
