Builds the standalone Vite client for each PR and publishes it as an OCI artifact at ghcr.io/rocketchat/rocket.chat-ui-preview (tags `pr-<number>` and the head SHA), where Rocket.Chat Desktop pulls it anonymously via `rocketchat://ui-preview?pr=<number>`. - `UI Preview Build` runs the PR's code on `pull_request` with read-only permissions and no secrets, and uploads the bundle as an artifact. - `UI Preview Publish` runs on `workflow_run`, checks the PR against GitHub's data (head SHA, fork, `ui-preview` label), pushes the artifact with oras and comments the Desktop links. It never extracts or runs the bundle. Fork PRs publish only with the label, which is removed after each publish. The production Vite build also needed two fixes: - Workspace packages whose entry is not `src/index.ts(x)` (base64, sha256, random) resolved to their unbuilt dist; the entry now follows the `browser`/`main` field back to its source. - `public/voice-call-popup.html` links to ui-voip's dist, so ui-voip is built with the other public asset packages.

Suggested labels: Suggested reviewers: Merge Risk: 🟡 Moderate · up to Preview functionality is incomplete and removed previews can remain or reappear; these workflow issues should be fixed before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The workflow separates preview builds from registry credentials and excludes fork builds. However, removing a preview is not reliably completed across cancellation and closure, so a withdrawn preview can remain available. The demonstrated exposure is limited to preview distribution; credential access and Desktop-side protections remain unverified. Retained concerns

`workflow_run` workflows only run from the default branch, so the separate publish workflow could not run until merged. The publish is now a second job of the same `pull_request` workflow, limited to PRs from this repository (forks and Dependabot do not receive CR_PAT). It only downloads the artifact and pushes it, never running the PR's code. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

When a PR loses the
previewlabel, the removal run can delete its tags while an earlier run is still publishing. GitHub Actions cancellation is cooperative, and thePush to ghcr.iostep has no current-state guard.

This lets anyone test a PR's web UI inside Rocket.Chat Desktop, against their own workspace, with no hosting other than GitHub.
One workflow,
UI Preview. On PRs it runs only when the PR has thepreviewlabel (adding it triggers a build; later pushes rebuild while it stays), and only for PRs from this repository; forks and Dependabot do not receiveCR_PAT. Every push todevelopalso publishes:develop.build(read-only): runsbuild:vitefor the standalone client and uploadsindex.html+bundle/as an artifact. That is about 14 MB gzipped with sourcemaps. The rest ofdist/ispublic/, which the server already serves.publish: downloads the artifact and pushes it withorastoghcr.io/rocketchat/rocket.chat-web:pr-<n>,:pr-<n>-<sha>and:<sha>(or:developon develop, deleting the develop builds it leaves untagged). It then posts or updates one PR comment with the Desktop links. This job holdsCR_PAT, so it never checks out or runs the PR's code.remove: when thepreviewlabel is removed, or a previewed PR is closed, deletes everypr-<n>/pr-<n>-*version and updates the PR comment. It only calls the API.Desktop side: RocketChat/Rocket.Chat.Electron#3525.
