Drop swagger-ui, document telemetry, add opt-outs (#7524) (#7757)
* docs: design spec for #7524 drop swagger-ui + privacy opt-outs

Three-deliverable plan: vendor RapiDoc to replace swagger-ui-express
(Scarf-injecting), add privacy.updateCheck and privacy.pluginCatalog
opt-outs for our two outbound calls, and ship PRIVACY.md as a public
stance doc.

* docs: implementation plan for #7524 swagger-ui + privacy opt-outs

Twelve TDD-flavoured tasks: privacy settings shape, UpdateCheck +
installer opt-outs (each with a failing-test-first cycle), admin
backend/UI plumbing, dependency drop, vendored RapiDoc, PRIVACY.md,
final verification matrix.

* feat(privacy): add privacy block to settings shape

Adds privacy.updateCheck and privacy.pluginCatalog, both defaulting to
true so behavior is unchanged until operators opt out.

* feat(privacy): honour privacy.updateCheck=false in UpdateCheck

check() and getLatestVersion() now early-return when the setting is
off. Logs once on first skip. The admin "update available" panel
already tolerates an undefined latestVersion.

* feat(privacy): honour privacy.pluginCatalog=false in installer

Extracts the gate into pluginCatalogGuard.ts so it can be unit-tested
under vitest without dragging in the CJS require() chain from
installer.ts. getAvailablePlugins() now throws the tagged disabled
error before any fetch.

* feat(privacy): emit results:catalogDisabled when pluginCatalog off

Short-circuits the four catalog-driven socket events. The install/
uninstall events are untouched so operators can still install by
plugin name even when the catalog is disabled.

* fix(bin): stalePlugins reads updateServer and honours privacy flag

Was hardcoding static.etherpad.org and ignoring opt-out. Now exits 0
cleanly when privacy.pluginCatalog=false.

* feat(api-docs): replace swagger-ui-express with RapiDoc shell

Drops the swagger-ui-express dep (third-party Scarf telemetry pixel,
see swagger-api/swagger-ui#10573) and serves /api-docs with a static
HTML shell that mounts <rapi-doc>. /api-docs.json is unchanged.

The vendored RapiDoc asset is added in the next commit so the tree is
broken for one diff hunk — pair this with the rapidoc-min.js commit
during review.

* feat(api-docs): vendor RapiDoc 9.3.4 (MIT) as static asset

Pinned bundle with checksum in VERSION. Replaces swagger-ui-dist which
shipped a Scarf telemetry pixel.

Disables RapiDoc's bundled Google Fonts request via load-fonts="false"
plus explicit regular-font/mono-font system stacks — RapiDoc's CSS
@font-face rules would otherwise fetch Open Sans from fonts.gstatic.com
at render time.

Also fixes the /api-docs route's res.sendFile to use an absolute path
resolved via settings.root (the previous {root: 'src/static'} was
resolved from CWD which is already src/, producing src/src/static).

* feat(admin): banner when plugin catalog is disabled

Subscribes to results:catalogDisabled and renders a localized info
banner on the plugins page. install/uninstall still function via CLI.

Refs #7524

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: PRIVACY.md and README/CHANGELOG pointers

Publishes Etherpad's stance on telemetry: two documented, opt-out
outbound calls; no third-party analytics; no install-time phone-homes
in our deps.

Refs #7524

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(admin): await checkPluginForUpdates and emit array on error

Qodo flagged that checkUpdates emitted the unresolved Promise (missing
await) and emitted {} for updatable on the error path, both breaking
the admin UI's expected string[] shape. Pre-existing bug surfaced when
the surrounding block was edited for the privacy.pluginCatalog gate.

Refs #7524

* feat(api-docs): swap RapiDoc for Scalar (actively maintained)

Per @SamTV12345's review on #7757: RapiDoc has been effectively
unmaintained for a while. Scalar (https://github.com/scalar/scalar)
is MIT-licensed, actively developed, and ships a self-contained
standalone bundle that works the same way for our purposes.

Privacy posture is preserved by configuring the embed:
  - withDefaultFonts: false   (no fonts.scalar.com woff2 fetch)
  - telemetry: false          (defensive)
  - agent.disabled: true      (no api.scalar.com/vector/* calls)
  - mcp.disabled:   true      (no MCP integration)
  - showDeveloperTools: 'never'
  - hideClientButton: true

Verified with headless Chromium: page loads /api-docs, mounts Scalar,
renders the Etherpad OpenAPI document, and makes zero requests to
any host other than localhost.

Vendor:
  - src/static/vendor/scalar/standalone.js     (@scalar/api-reference 1.57.2)
  - src/static/vendor/scalar/VERSION           (sha256 pinned)
  - src/static/vendor/scalar/LICENSE           (MIT)
Removed:
  - src/static/vendor/rapidoc/*

# Privacy in Etherpad
## What this document is
A complete, current list of every network call Etherpad's own code makes
to a third party, plus how to turn each one off. Plugins are out of
scope — audit any plugin you install.
## TL;DR
Etherpad ships with two outbound calls to `etherpad.org`. Both are
documented below. Both can be disabled with a single config value each.
No analytics, no usage pings, no third-party SDKs at runtime.
## Outbound calls
### 1. Version check
| | |
|---|---|
| URL | `https://static.etherpad.org/info.json` (override via `updateServer`) |
| Frequency | hourly while the server runs |
| Payload | GET only; `User-Agent: Etherpad/<version>` |
| Purpose | surface an "update available" notice in the admin panel |
| Disable | set `privacy.updateCheck: false` in `settings.json` |
| Source | `src/node/utils/UpdateCheck.ts` |
### 2. Plugin catalog
| | |
|---|---|
| URL | `https://static.etherpad.org/plugins.json` (override via `updateServer`) |
| Frequency | on admin-plugins page load (cached 10 min) |
| Payload | GET only; same `User-Agent` |
| Purpose | list installable `ep_*` plugins in the admin UI |
| Disable | set `privacy.pluginCatalog: false` in `settings.json` (manual install via CLI still works) |
| Source | `src/static/js/pluginfw/installer.ts` |
## What we removed
`swagger-ui-express` was dropped because the upstream npm package
injects a Scarf analytics pixel that cannot be disabled at install or
runtime (see [swagger-api/swagger-ui#10573](https://github.com/swagger-api/swagger-ui/issues/10573)).
`/api-docs` is now served by a vendored copy of [Scalar](https://github.com/scalar/scalar)
(MIT) with no outbound calls. The shell explicitly opts out of Scalar's
default font fetch (`withDefaultFonts: false`) and analytics
(`telemetry: false`), and pins a system-font stack via CSS.
`@scarf/scarf` is listed under `ignoredBuiltDependencies` in
`pnpm-workspace.yaml`, so its postinstall pixel is suppressed even if a
future transitive dep pulls Scarf in.
## What we will not add
- usage analytics or telemetry SDKs
- crash reporters that send data without explicit opt-in
- third-party CDN dependencies at runtime
- dependencies whose install or runtime phones home
## Plugins
Third-party plugins are out of this guarantee. Plugins run in your
Etherpad process with full access; audit any plugin you install.
