 - **Self-contained state.** The bootstrap creates a fresh stack with **zero** dashboards / alerts / etc. — never assume pre-existing data. Two cleanup shapes are valid; pick based on the spec size:
   - **Per-test `try / finally`** — small specs (~ <10 scenarios) where each test owns its data.

 - **The list pages render zero-state when the workspace is empty.** Many locators (search input, sort button, `new-dashboard-cta` testid, "All Dashboards" header) are absent in zero-state. A 30s timeout on those usually means the workspace was empty — seed first via `createDashboardViaApi`.
 - **The "Enter dashboard name…" inline field is a `RequestDashboardBtn` (template-request feedback form), not a create flow.** Tests that try to use it to create a named dashboard will silently no-op. The only UI create paths are the "New dashboard" dropdown → "Create dashboard" (default name "Sample Title", see `DEFAULT_DASHBOARD_TITLE`) or "Import JSON".
 - **Auth.** `tests/e2e/fixtures/auth.ts` logs in once per worker and caches `storageState` (cookies + localStorage with `AUTH_TOKEN`). For API-driven seeding/cleanup, use `authToken(page)` from `helpers/dashboards.ts` and pass `Authorization: Bearer <token>`. Never re-implement login.
+- **Extended fixtures.** Domain-specific fixtures extend `auth` and add seeded data. Alerts uses `fixtures/alerts/alert-rules` (worker-scoped rule list, test-scoped factory) and `fixtures/alerts/alert-history` (extends alert-rules, waits on ruler evaluation). See [docs/contributing/tests/e2e.md](../../docs/contributing/tests/e2e.md) for the pattern. When a test fails on missing data, check if it imports the wrong fixture level.
 - **Ant Design popovers** (sort menu, action menu) are click-toggle. The trigger element is often an inline `<svg>` with a `data-testid` — clicking it opens the popover; clicking it again closes. After selecting an option, the popover auto-closes. If a test interacts with the popover twice, wait for the menu items to be visible explicitly between toggles.
 - **Artifacts.** Every failed test writes to `tests/e2e/artifacts/results/<test-slug>/` — the `error-context.md` accessibility snapshot is the fastest way to see what the page actually looked like when it failed.
 - **Type-check.** After edits, run `npx tsc --noEmit -p tests/e2e/tsconfig.json` if it succeeds, or rely on `npx playwright test --list` to validate the spec parses.

 Rule of thumb: if it's a `test.extend` fixture, put it in `fixtures/`. If it's a function you call explicitly (or a constant the function uses), put it in `helpers/`. If it's a static file the helpers read, put it in `testdata/`.
 
+### Extended fixtures
+
+For features needing complex setup (API-seeded data, ruler evaluation waits, cleanup), create domain-specific fixtures that extend `auth`. Group them in `fixtures/<domain>/`.
+
+**Fixture scopes:**
+- **test scope** — fresh data per test. Use for mutations (edit, delete, rename).
+- **worker scope** — shared across tests in one worker. Use for read-only data. Worker scope pays the setup cost once per worker instead of once per test.
+
+**The alerts pattern** (`fixtures/alerts/`) demonstrates extending fixtures:
+
+```
+fixtures/alerts/
+├── alert-rules.ts   # extends auth — worker-scoped rule list + test-scoped factory
+└── alert-history.ts # extends alert-rules — adds history fixtures (waits on ruler)
+```
+
+Specs import from the fixture they need:
+
+```ts
+// List tests — just need rules, no history
+import { test, expect } from '../../../fixtures/alerts/alert-rules';
+
+// History tests — need history rows from ruler evaluation
+import { test, expect } from '../../../fixtures/alerts/alert-history';
+```
+
+**When creating new fixtures:**
+
+1. **Identify scope** — Will tests mutate the data? If yes, test-scoped. If read-only, worker-scoped.
+2. **Group by domain** — Put fixtures in `fixtures/<domain>/`. Helpers in `helpers/<domain>/`.
+3. **Extend existing fixtures** — Chain from `auth` or another fixture to inherit its setup.
+4. **Handle timeouts** — Worker-scoped fixtures that wait on backend processing need explicit timeouts.
+5. **Clean up** — Always delete seeded data in the fixture teardown (after `use()`).
+6. **Extract logic into functions** — Keep the `test.extend()` block lean; move setup/teardown logic to named functions so the extend block reads as a manifest of "what fixtures exist."
+
 Each spec follows these principles:
 
 1. **Directory per feature**: `tests/e2e/tests/<feature>/*.spec.ts`. Cross-resource junction concerns (e.g. cascade-delete) go in their own file, not packed into one giant spec.

-Loading order in `playwright.config.ts`: `.env` first (user-provided, staging), then `.env.local` with `override: true` (bootstrap-generated, local mode). Anything already set in `process.env` at yarn-test time wins because dotenv doesn't touch vars that are already present.
+Precedence in `playwright.config.ts`, lowest to highest: `.env` (user-provided, staging) → `.env.local` (bootstrap-generated, local mode) → whatever is already in `process.env`. The config parses both files itself and only fills in keys the environment does not already define, so exporting a variable always wins:

+# runs against a locally served frontend, not whatever .env.local points at
+SIGNOZ_E2E_BASE_URL=http://127.0.0.1:3301 pnpm test tests/alerts

+This is deliberately not `dotenv.config({ override: true })`. That flag makes the *file* beat `process.env`, which silently discarded exported values — including the `SIGNOZ_E2E_BASE_URL` in `pnpm test:staging`, whenever a `.env.local` happened to exist.
