+## Navigation coverage
+
+Every `.mdx` page in the shipped taxonomy (root pages plus `architecture/`,
+`api-reference/`, `contracts/`, `guides/`, `reference/`, and `sdk/`) must be
+registered in the `docs.json` navigation tree, and every navigation entry must
+resolve to a real file. This is enforced by:
+
+```bash
+npm run check:nav-coverage
+```
+
+The checker (`scripts/check-nav-coverage.mjs`) scans for `.mdx` files that are
+missing from `docs.json` and for nav entries that point at files that no longer
+exist. Run it after adding, renaming, or removing a page:
+
+```bash
+node scripts/check-nav-coverage.mjs
+```
+
+Note: `docs.json` is strict JSON — do not add `//` comments to it, the Mintlify
+CLI rejects them. Keep this file comment-free.
+

-non-blocking Stellar testnet job is reserved for end-to-end snippet validation
