PDFs rewrite in-document .md/.html links to sibling PDFs. Catalog start page is GETTING-STARTED (install, first-up, monitor). Billing and user platform is zappier-edge (original ~/zappier tree).
Compose-ready workspace: packages/zappier (rate card, portal, Stripe), packages/verae-zapier-middleware (timestamp + NATS), packages/verae-zapier (CLI app), vendor/zapier-platform, and research/zapier vendor corpus. Gate 0 structure checks pass. Product code and research are not yet wired.
