# Cross-domain acceptance scenarios (turn into Playwright suites at WP-02)

1. Launch with systems-thinking manifest. Home headline and available categories are systems-specific. Browse `concept`, filter/search `feedback`, open detail, navigate a relation, return via browser history. Show source and uncertainty context.
2. Rebuild or relaunch with software-architecture manifest **without editing UI source**. Home and kind pages change accordingly. Open `adapter`, follow `interface`, inspect backlink; `cancer` never appears in navigation or component module imports.
3. URL filter state is bookmarkable and remains after refresh and back-forward navigation.
4. Keyboard-only usage covers command search, facet control, result row and related-entity list.
5. Ingestion regression: same source batch twice yields byte-identical canonical projection (after canonical sorting); source removal behavior varies correctly by snapshot/incremental mode.
6. Validation rejects duplicate IDs, dangling relation targets, and missing rights data under strict public-publish policy.
7. Conflicting claims from two sources appear as disputed, not silently overwritten.
8. Graph handles cycles, multi-parent objects and high-degree nodes with explicit limits.
9. Every adapted upstream file includes applicable MIT notice and is traceable to a pinned commit.

10. Under the separately authorized OnCo reference-slice profile, verify forward and reverse relations, page semantics, filters, attribution, stable URLs and 3-hop journeys against the pinned upstream reference; see `tests/onco-reference/README.md`.
