Verify a preview build against one project

Installs an isolated global vp built from a registry bridge commit build and runs vp migrate on a specified local project. The global CLI and the migrated project both pin vite-plus/vite to the clearly-defined 0.0.0-commit.<sha> build. vp migrate itself writes the bridge registry into the project's .npmrc (or .yarnrc.yml for Yarn Berry) so the deps resolve, during this run and in the project's own CI; this script only force-stages that file past .gitignore.

Required inputs: a <PR-or-SHA> (the build to verify) and a <project-path>. If either is missing from the request, ask the user for it — never guess the PR/SHA, as the build under test is the user's choice.

.github/scripts/test-pkg-pr-new-migrate.sh <PR-or-SHA> <project-path> [migrate-options...]
# e.g.
.github/scripts/test-pkg-pr-new-migrate.sh 1891 /path/to/npmx.dev --no-interactive

• First arg is a PR number or commit SHA; the script resolves the immutable commit via the bridge x-commit-key header and verifies the bridge serves it (the preview publish workflow, triggered by the preview-build label, registers each commit).
• Never touches ~/.vite-plus; clears only the workspace ROOT lockfile + node_modules before migrating; refuses a dirty worktree unless ALLOW_DIRTY=1; prints the project's git status/diff at the end — inspect that to confirm the migration result.

The build under test must include the "migrate writes the bridge registry" feature (this session's work / current branch head onward). The harness no longer writes the registry itself — it relies on vp migrate doing it. Testing an older build with this harness would leave the project with no bridge registry, so its deps resolve from npmjs (ERR_PNPM_NO_MATCHING_VERSION on the 0.0.0-commit.<sha> version). Always verify a fresh build of the branch, not a stale published commit.

The script prints the resolved versions at the end, querying one package at a time (npm/yarn/bun why only accept a single package; -r is pnpm-only). Each must resolve to exactly ONE version: vite-plus and vite at the expected 0.0.0-commit.<sha> (vite via the @voidzero-dev/vite-plus-core alias), vitest at the bundled upstream version. Multiple versions, or a stale/wrong version, means the migration or install is broken. To re-check by hand:

cd <project-path>
# pnpm: one call, recursive across workspaces
vp why -r vite-plus vite vitest
# npm / yarn / bun: one package per call, no -r
vp why vite-plus && vp why vite && vp why vitest
