# WP-05 — Quality system & upstream experience parity

**Purpose:** Measure architectural independence and UX faithfulness.

**Dependencies:** see `INDEX.md`. **Status:** planned. **Owner:** to assign. **Estimate:** to refine after WP-00.

## Work packages

- [ ] Automate schema/ingest/ui/e2e tests and two-domain switch tests.
- [ ] Run accessibility, screenshot comparison, core web vitals and responsive audits.
- [ ] Report provenance completeness, stale counts, unresolved refs and ingestion failure classes.
- [ ] Document deviations from upstream and verify third-party notices.
- [ ] Harden inputs and public snapshot generation.

## Acceptance gates

- [ ] Tests run in CI; no material keyboard accessibility failures.
- [ ] Two unrelated domains pass all critical journeys.
- [ ] Source and license completeness report available.

## Key risk / mitigation focus

R7: tests approximate but do not prove usability. Log evidence and deviations in the workplan review before marking complete.

## Evidence artifacts

Pull requests, test logs, pinned artifacts, screenshots or comparison report where applicable. Add explicit `ImplementationNotes.md` and `Review.md` on completion; do not mark a gate passed without a verifiable link.

## Reference-oracle testing extension

Add WP-07: compare the *same permitted pinned OnCo slice* through the original implementation and generic Content Explorer, including behavioral journeys and visual snapshots. Public CI remains synthetic-only.
