e2e-tests

Assert on a seeded row such as a name, slug, or count rather than page chrome, because every page renders its empty state when a query fails. Then point BACKEND_URL at a dead port and confirm the spec goes red before trusting it.

An open Radix dialog removes the rest of the page from the accessibility tree, so getByRole queries resolve to nothing. Use submitDialog from e2e/helpers.ts, which waits on the write response and the dialog closing instead of a fixed timeout.

Add the fixture to e2e/seed.setup.ts so it is created through the UI, and export its name as a constant from e2e/helpers.ts. Assert against those constants in specs, and never create data inside a spec unless creating it is the behavior under test.

The backend commits inside a FastAPI Depends-with-yield exit code that runs after the response is sent, so a single read right after a write can miss the row. Poll with the nowThere helper instead of performing one read.

The database image must be pgvector/pgvector:pg16, not stock Postgres. The RAG store issues CREATE EXTENSION IF NOT EXISTS vector on first write, and stock Postgres answers that the vector extension is not available.

E2E is only for journeys crossing the whole system like sign in, build, publish, run, and approve. A permission hiding a button belongs in a frontend integration test with a mocked API, a service rule in a unit test, and a constraint in a backend integration test.
