 Mintlify's `navigation` object (`tabs`/`anchors`/`dropdowns`/`products`/`versions`/`languages`/`groups`/`pages`) is fully config-declared. **Prefer restructuring content into folders**, not porting the config verbatim:
 
-- **`groups`** (`{ group, pages: [...] }`) → a folder per group. The `group` name → the folder's humanized name or a `meta.ts` `title`. Nested groups → nested folders. `expanded: false` → `meta.ts` `collapsed: true` (inverted). `tag` → the folder/page `sidebar.badge`. **Folder metadata is a `meta.ts` module** (`export default defineMeta({ title, icon, order, collapsed, pages })`), a TypeScript file — **not** JSON. Blume does not read a `meta.json`, so any folder-level config you carry over from the source (or hand-write to preserve a group's label/order/collapse) must be authored as `meta.ts`. (Render mode — flat/group/page — is **not** a `meta.ts` field; it's the global `navigation.sidebar.display` in `blume.config.ts`.)

(Render mode — flat/group/page — defaults to the global `navigation.sidebar.display` in `blume.config.ts`; a folder overrides its own group with `meta.ts` `display`, or `sidebar.display` in its `index` page's frontmatter.)
 - **Config-only nested groups don't exist on disk — you must materialize them, or they flatten silently.** A nested `{ group, pages }` almost never has a matching subfolder: its pages sit **flat in the parent directory** (e.g. `platform/analytics/getting-started.mdx`, `…/quick-reference.mdx`) and the grouping lives **only** in the `docs.json` `pages` array. If you leave the files where they are, filesystem-derived nav sees one flat folder and the inner group vanishes — Mintlify's `Analytics → Reference → {…}` becomes a flat `Analytics → {…}`. To preserve it you must **either** move those pages into a real subfolder (`platform/analytics/reference/`, with a `meta.ts` for the label/`collapsed`), **or** declare the shape in an explicit `navigation.sidebar`. Walk **every** `pages` array recursively and treat any nested `group` object as a folder-move to plan, not files already in place. When inventorying the nav (workflow step 2), record the config nesting depth separately from the on-disk depth — they diverge exactly here.
 - **This is the canonical case for `navigation.sidebar` over folders.** Materializing a purely-presentational nested group as a subfolder changes URLs (`/platform/analytics/getting-started` → `/platform/analytics/reference/getting-started`) for no reason other than a visual grouping, forcing a `redirects` entry per page. When you want to keep the nesting **and** the URLs, an explicit `navigation.sidebar` group (`{ label, items }`) is the better trade — it nests the existing routes without moving any file. Pick per group; don't reflexively flatten.
 - **`pages`** entries are page refs (paths without extension) → files at the corresponding path. An entry that's `"GET /path"` is an OpenAPI endpoint stub → **delete it** (Blume generates these; see OpenAPI).
