Summary

Running vp pack --workspace 'packages/*' from a library workspace can build only the root entry and exit successfully. Selecting workspace members through pack.workspace has the same problem. A member-name filter can then leave the build with no output.

Expand each workspace pack configuration before resolving and filtering individual builds. A patch to the pinned tsdown dependency exposes its existing workspace resolver so the CLI can reuse its member config loading and track those files in watch mode.

vite.config → workspace members → member configs → filter → build

Evidence

• On 1.5.0 the regression fixture produced a root bundle with value 99. The new CLI snapshot checks the actual member exports (11 and 55), an exclusion, a CLI override and a single-member filter. It also checks that no root bundle exists.
• A syntax error in the selected member exited 1. Fixing the entry restored the build. Editing a member config in watch mode rebuilt the renamed output.
• The focused CLI snapshot and repository-wide vp check passed. The unit suite passed 3,403 tests with one skipped.

Merge Danger

Door: Two-way. The CLI change and dependency patch can be reverted together.

Blast Radius: Pack. The patch targets tsdown 0.23.4 and needs review when that dependency changes.
