Public barrels (`@fusion/core`, `@fusion/engine`, `app/api.ts` → legacy) stay stable. ## Test plan - [x] `@fusion/core` typecheck - [x] `@fusion/engine` typecheck (pre-existing playwright-core noise only) - [ ] CI merge gate **Stack:** #2394 → #2397 → **this PR**
fusion-plugin-quality
First-party Fusion plugin that makes task QA easy and visual.
Surfaces
- Quality hub (left sidebar): project-wide test run history and plans
- Task QA tab: action-first task quality work
- Task-scoped preview / test server (worktree cwd)
- Allowlisted targeted tests + report viewer
- Screenshots / visual evidence (task artifacts)
- Suggested test cases (advisory checklist)
- PR checks, browser verification handoff
Design principles
- Orchestrates existing verification (
testCommand, gate, verify-fast) — does not replace the merge gate - Composes Dev Server process patterns and the artifact registry
- Composes
fusion-plugin-agent-browserfor browser verification (soft dependency) - Never uses port 4040; never free-form shell as the default path
- Advisory results only — does not change merge eligibility
