file.
YES
## What kind of change does this PR introduce?
Refactor, bug fix.
Part 1 of 6 in a stack that splits the library redesign into reviewable
pieces. This one is the foundation the rest build on and has no visual
change.
## What is the current behavior?
Three build steps each reimplement "where does this registry file land
in the user's project": `process-registry`'s `getDefaultPath`,
`registry/utils`' `uniqBy` on `file.path`, and the Markdown exporter.
They disagree, which produces real bugs:
- A Vue block whose files come from `node_modules/@supabase/vue-blocks/`
keeps its package path, so the installer writes the package folder into
the user's project.
- `registryItemAppend` builds its `docs` string from `(item.docs,
items.flatMap(...))` — a comma expression, so the item's own docs are
discarded.
- A name collision between a block file and its client's file silently
keeps one of the two.
- Install commands guess the CLI family from substrings in the item
name, so `infinite-query-composable` — a Vue block with neither "vue"
nor "nuxtjs" in its name — gets the React CLI.
- Production Vue installs use `@supabase/<name>`, but the `@supabase`
namespace is registered with shadcn, not shadcn-vue.
- `build:registry`, `build:content`, `build:markdown` and `build:llms`
run in parallel, but the last three read `public/r`.
## What is the new behavior?
`lib/registry-resolution.ts` owns installed-path derivation, first-party
dependency naming, deduplication, and cycle detection, and every
consumer calls it. `build-registry` validates the whole registry against
shadcn's schema and resolves every item, so a broken reference fails the
build instead of shipping. `clean-registry` throws rather than logging
past a failure.
Pages declare their install `framework` explicitly instead of it being
inferred, and production Vue installs use the absolute registry URL.
The build steps are serialized behind `build:prepare`, and a new
`library-tests.yml` workflow runs the library's tests, checks the
generated registry is committed, and builds the app.
## Additional context
Regenerated registry artifacts are the mechanical result of the
resolution fix — the Vue client items and the OAuth consent items that
gained their client's docs.

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
Feature: agent-readable markdown pages for the UI library docs.
## What is the current behavior?
Library docs are HTML-only. `llms.txt` lists page titles, but there is
no `.md` body an agent can fetch.
## What is the new behavior?
Each docs page is also served as markdown:
- Build-time MDX → markdown (`pnpm --filter library build:markdown`)
- `GET /library/docs/{slug}.md` (and `Accept: text/markdown`)
- HTML pages advertise `rel=alternate` `text/markdown`
- `llms.txt` links to the `.md` URLs
This is the base of a stack. The prompt-tab PR sits on top:
https://github.com/supabase/supabase/pull/49566
## Additional context
Interactive previews are omitted from the markdown. `BlockItem` emits
the production `npx shadcn add` command so agents still get an install
path.
## To test
1. `pnpm --filter library dev` (generates markdown in `predev`).
2. Open http://localhost:3004/library/docs/nextjs/password-based-auth.md
— markdown with the install command, file tree, and setup steps; no
interactive previews.
3. Open the same path without `.md` — HTML docs unchanged (no prompt tab
in this PR).
4. `curl -H 'Accept: text/markdown'
http://localhost:3004/library/docs/nextjs/password-based-auth` should
also return markdown.
5. http://localhost:3004/library/llms.txt — links should end in `.md`.

## Summary by CodeRabbit
* **New Features**
* Documentation pages are available as Markdown through `.md` URLs and a
dedicated endpoint.
* Markdown is generated automatically during development and production
builds.
* Generated content preserves front matter, links, callouts,
installation instructions, and supported documentation elements.
* Installation commands support npm, pnpm, yarn, and bun for React and
Vue projects.
* **Bug Fixes**
* Improved Markdown file handling, link rewriting, and content
negotiation.
* **Tests**
* Added coverage for Markdown conversion, content negotiation, and
installation commands.
