 Docusaurus `^3.10.x` on the shared `stackql/docusaurus-config` (vendored to `.shared-config/` by `yarn vendor-config` in `prebuild`/`prestart`). Site-local files only: `provider.js` (`providerName`, `providerTitle`), `docusaurus.config.js` (createConfig + registry logos + `config.presets[0][1].docs.showLastUpdateTime = true;`), `sidebars.js`, `scripts/sanitize-docs.mjs`, `src/` (CopyableCode, SchemaTable, StackqlDeployDropdown, theme overrides), `static/` (CNAME `<provider>-provider.stackql.io`, favicons, manifest, registry logos, `stackql-featured-image.png`, `stackql-<provider>-provider-featured-image.png`). No Docusaurus boilerplate (no undraw images, HomepageFeatures, stock README).
 
+The sidebar (`sidebars.js`) has one shape on every provider site: a `Back to StackQL Docs` link first (`type: 'link'`, `href: '/stackqldocs'`, `className: 'sidebar-back-link'`), then `All Providers` (`href: '/providers'`), then the `<Title> Provider` category linked to `provider-intro` with the autogenerated `services` tree. Both hrefs are shared-config redirect routes that the vendored redirects plugin registers on the site (they forward to `https://stackql.io/` and `https://stackql.io/providers`), so they render as internal links and pass the broken-link checker; the `.sidebar-back-link` rules in `src/css/global.css` draw the arrow and the divider, matching the query library site. Copy both from the template rather than re-deriving them.

 `headerContent1.txt` is the front matter + one-paragraph pitch; `headerContent2.txt` is the getting-started page: See also / Installation (`REGISTRY PULL`) / Scope / Authentication (env vars, bash and PowerShell) / the scoping variable / Rate limit / Beta labelling / Example Queries - lead with the queries the provider exists for (estate inventory, posture set, the flagship, provisioning with INSERT/UPDATE/EXEC/DELETE, a cross-provider UNION). Examples must be runnable against the generated surface (snake names, quoted keywords).
 
 The example section has one shape on every provider site, so the table of contents reads the same everywhere:
