This is a standalone product bundle, kept separate from the original tier catalog. The main storefront's product loader only reads Markdown files directly inside its root products/ directory, so this bundle's listing is excluded from the existing Gumroad sync and catalog build until you deliberately integrate it.
products/apex-codex-sovereign-infrastructure.md— product listing source, including Gumroad metadata.core/— downloadable local-first Node.js command engine and setup guide.
Review the listing and attach the downloadable core/ package as the customer deliverable in Gumroad. When you are ready to include this product in the current project's Gumroad sync, copy its Markdown file into the project's root products/ directory. The root npm run push:gumroad processes every product in that directory, so it will sync the full catalog, not just Apex.
The Gumroad ID and URL in the listing are blank until the product is created and published. Keep the working bundle copy here as the separate source of truth, or copy the updated metadata back into this bundle after syncing.
The existing catalog build and Pages workflow operate on the project root. To include an Apex product page in that catalog, copy the listing into the root products/ directory, then run npm run validate and npm run build:site. This intentionally adds Apex to the main catalog. To keep it independent, publish this bundle from a separate repository or deployment project; the core/ CLI itself is a local downloadable product and is not a Pages website.
See core/README.md. The CLI requires Node.js 20 or newer and stores its ledger, summaries, and backups locally within its working directory by default.
