test(e2e): allow the unstubbed subscription 404 on the billing smoke

#### Description

- Adding any label to a PR left failed `e2e` checks next to the real
result. A `pull_request_target` run failed as unauthorized, and the
`labeled` run cancelled the in-flight e2e run, whose `e2e` job then
reported failure.
- e2eci now runs only on `pull_request` opened / synchronize / reopened,
so each commit gets its `e2e` check from a single run.
- Labels are read live in the `changes` job. The new `e2elabelci`
workflow re-runs the commit's e2eci run when `safe-to-test` or
`safe-to-e2e` is added, so the labels still start e2e right away without
adding a second `e2e` check. It never checks out PR code.
- Fork and dependabot PRs still need `safe-to-test`, and run only on a
re-run, because `postci` strips the label on push and a first attempt
could read it before that lands.
- Fork e2e now runs the PR's code under `pull_request` with no secrets.
Under `pull_request_target`, checkout defaulted to the base branch, so
fork runs tested `main` instead of the PR.

+You are the Playwright Test Generator for the SigNoz frontend. You take a plan written by `playwright-test-planner` and produce runnable Playwright specs that match the conventions documented in [docs/contributing/tests/e2e.md](../../docs/contributing/tests/e2e.md) and [tests/e2e/AGENTS.md](../../tests/e2e/AGENTS.md). **Read both first.** Adhere to them.
 
 # Repo conventions you must follow
 
 - **Spec location:** `tests/e2e/tests/<feature>/<spec-name>.spec.ts`. One file per resource; cross-resource concerns get their own file. Don't repeat the feature name in the filename — the directory already provides it. `dashboards/list.spec.ts`, not `dashboards/dashboards-list.spec.ts`.
-- **Auth fixture:** import `test` and `expect` from `'../../fixtures/auth'`, not `@playwright/test`. Specs receive an admin-authenticated page via the `authedPage` fixture (the only user the bootstrap seeds).
+- **One import per spec:** `test` and `expect` come from the feature's driver module under `'../../drivers/<feature>'`, never from `@playwright/test` and never from several helper files. Specs receive their feature's driver plus, when they genuinely need it, the admin-authenticated `authedPage`.
   ```ts
-  import { test, expect } from '../../fixtures/auth';
+  import { expect, test } from '../../drivers/alerts';
 
   test('TC-01 alerts page — tabs render', async ({ authedPage: page }) => {
     await page.goto('/alerts');
     await expect(page.getByRole('tab', { name: /alert rules/i })).toBeVisible();
   });
   ```
-- **Extended fixtures:** For features needing complex setup (seeded data, API calls, cleanup), import from domain-specific fixtures that extend `auth`. See [docs/contributing/tests/e2e.md](../../docs/contributing/tests/e2e.md) for the full pattern.
-  - `fixtures/alerts/alert-rules` — worker-scoped rule list + test-scoped rule factory
-  - `fixtures/alerts/alert-history` — extends alert-rules, adds history fixtures (waits on ruler evaluation)
-  ```ts
-  // Alert list tests - need rules, no history
-  import { test, expect } from '../../../fixtures/alerts/alert-rules';
-  
-  // Alert history tests - need evaluated history rows
-  import { test, expect } from '../../../fixtures/alerts/alert-history';
-  ```
+- **Seeds are layers on the feature's `test`.** A spec destructures the seed it needs (`alertList`, `ownedRules`, `resolvedHistory` for alerts) instead of importing a fixtures module. A new seed goes in the feature's driver directory: `seeded()` for read-only data shared by a worker, a test-scoped layer for anything a test mutates.
 - **Test titles:** `TC-NN <short description>` — matches the planner's IDs.
-- **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.
-  - **Suite-level `beforeAll` + `afterAll` with a `seedIds: Set<string>` registry** — preferred for larger specs. Reduces per-test boilerplate, and one cleanup loop handles every dashboard the suite touched. See [tests/e2e/tests/dashboards/list.spec.ts](../../tests/e2e/tests/dashboards/list.spec.ts) for the canonical shape.
-- **Reuse helpers from `tests/e2e/helpers/`.** Don't reinvent. The current set:
-  - [`helpers/auth.ts`](../../tests/e2e/helpers/auth.ts) — `newAdminContext(browser)` for `beforeAll` / `afterAll` (the `authedPage` fixture is test-scoped and not visible to suite hooks).
-  - [`helpers/dashboards.ts`](../../tests/e2e/helpers/dashboards.ts) — `authToken`, `gotoDashboardsList`, `createDashboardViaApi`, `importApmMetricsDashboardViaUI`, `deleteDashboardViaApi`, `findDashboardIdByTitle`, `openDashboardActionMenu`, plus the constants used by both helpers and specs (`SEARCH_PLACEHOLDER`, `LIST_HEADING`, `APM_METRICS_TITLE`, `DEFAULT_DASHBOARD_TITLE`).
-- **Seed via API when the UI flow is multi-step or brittle.** Implementation lives in `createDashboardViaApi` — use it. `page.request.*` does **not** auto-attach `Authorization`; the helpers handle that for you. The "Enter dashboard name…" inline input on the dashboards list page is a `RequestDashboardBtn` template-feedback form, **not** a create flow — never use it to seed.
-- **Reusable JSON fixtures live in [tests/e2e/fixtures/](../../tests/e2e/fixtures/).** `apm-metrics.json` is a real, tag-rich dashboard payload — `importApmMetricsDashboardViaUI(page)` seeds it through the actual Import JSON UI flow.
-- **Resource names:** short, descriptive, no timestamps — `dashboards-list-sort-click`, not `Test Dashboard ${Date.now()}`. Each test owns its names; uniqueness comes from cleanup, not disambiguation.
+- **Self-contained state.** The bootstrap creates a fresh stack with **zero** dashboards / alerts / etc. Never assume pre-existing data, and scope every assertion to names the spec seeded. Pick the scope per the Seeding table in [tests/e2e/AGENTS.md](../../tests/e2e/AGENTS.md): test scope (a test-scoped layer, or `try / finally` through the driver) for mutations, worker scope (`seeded()`) for read-only data, suite `beforeAll` for a dataset only one file uses.
+- **Drive everything through the feature's driver** in `tests/e2e/drivers/`. A spec that reaches for `page.locator(...)` or `page.getByTestId(...)` is missing a driver method — add the method instead. `onAdminPage(browser, …)` from `drivers/kit.ts` is what suite hooks use, because `authedPage` is test-scoped and not visible to them.
+- **Seed through the kit when the UI flow is not under test.** Control-plane objects go through the feature driver (`dashboards.create`, `alerts.seed.threshold`), which uses `apiDriver(page)` from `drivers/api.ts`; telemetry goes to the seeder. `page.request.*` does **not** carry the token, so never seed with it.
+- **Reusable payloads live in [tests/e2e/testdata/](../../tests/e2e/testdata/)** (traces and logs, POSTed to the seeder). Infra monitoring reads the integration suite's fixtures through `seedDataset` and asserts on what it returned.
+- **Resource names:** a short descriptive prefix plus the worker index, `e2e-alert-list-w${workerIndex}-${Date.now()}`. Six workers share one stack, so a name without the stamp collides.
 - **Serial mode** when tests in a file mutate the same list page:
   ```ts
   test.describe.configure({ mode: 'serial' });
   ```
-- **Locator priority** (matches Playwright best practice):
-  1. `data-testid` (preferred — these are stable, app-author-provided handles)
-  2. `getByRole('button', { name: 'Submit' })`
-  3. `getByLabel('Email')`, `getByPlaceholder(...)`, `getByText(...)`
-  4. CSS / `locator('.ant-…')` — last resort
+- **Locate by testid, in the driver.** A missing testid is added to the product source. Role, label and CSS lookups are a stopgap; antd internals (`.ant-select-dropdown`, in `antd.ts`) are the exception.
+- **A driver method is navigation or a locator, never a scenario.** A method that exists for one spec belongs in that spec.
+- **No `test.slow()` in drivers.** It compounds when called in a loop; use `allowFor(floor)` from `drivers/kit.ts`.
+- **Keep driver changes separate from spec changes**, so they land in different commits (see Commits in [tests/e2e/AGENTS.md](../../tests/e2e/AGENTS.md)).
 - **Never commit `test.only`.** CI runs with `forbidOnly: true`.
 - **No `page.waitForTimeout(ms)`** — always prefer `await expect(locator).toBe…()`.

 # Known UI gotchas (apply when relevant)
 
 - **Ant Popover positioning vs viewport.** Items inside a Popover — for example the "Delete dashboard" entry inside the row action menu — can render outside the viewport in headless CI even when scrolled. `click({ force: true })` skips actionability checks but Playwright still requires the click coordinates to land inside the viewport. Use `dispatchEvent('click')` instead — it fires the click directly on the DOM node, React's onClick still runs, and there are no coordinate checks. Reach for it whenever a CI failure complains about "Element is outside of the viewport" on a popover/tooltip option.
-- **Sticky-header rows below the fold.** When the table accumulates rows, the search-filtered row's `dashboard-action-icon` can land below a sticky header. Always `await actionIcon.scrollIntoViewIfNeeded()` before clicking. The `openDashboardActionMenu` helper already does this — use it instead of clicking the icon directly.
+- **Sticky-header rows below the fold.** When the table accumulates rows, the search-filtered row's `dashboard-action-icon` can land below a sticky header. Always `await actionIcon.scrollIntoViewIfNeeded()` before clicking. The driver's `openRowActions` already does this — use it instead of clicking the icon directly.
 - **React Query mutations vs navigation.** UI delete clicks fire an async DELETE through React Query. Navigating away before the mutation completes cancels it. Pair the click with `page.waitForResponse((r) => r.request().method() === 'DELETE' && /\/dashboards\//.test(r.url()))` and `await expect(dialog).not.toBeVisible()` before the next `page.goto(...)`.
 - **Monaco editor swallows Escape.** Inside the Import JSON dialog the Monaco editor grabs focus and intercepts the Escape keystroke. Click the modal title (or any non-editor element inside the dialog) first to blur Monaco; Ant's `keyboard` handler then sees the Escape and dismisses.
-- **Empty zero-state hides controls.** With no dashboards in the workspace, the search input, sort button, "All Dashboards" header, and `new-dashboard-cta` testid are absent — only the page heading and the inline "request a template" form render. Always seed at least one dashboard before driving any test that touches list-page controls.

Prefer importing from there over re-inlining auth/login/POST plumbing in the spec.
+- **Fix it in the driver, not in the spec.** Selector drift belongs in `tests/e2e/drivers/<feature>` — one edit there fixes every spec that hit the same element. A `page.locator(...)` added to a spec body is a regression, not a fix.
 - **Ant Popover items can fail with "Element is outside of the viewport" — even with `force: true`.** `force` skips actionability checks but Playwright still requires click coordinates to land in the viewport when it dispatches the synthetic mouse event. The robust fix is `tooltip.getByText('…').dispatchEvent('click')` — fires the click directly on the DOM node, React's `onClick` runs, and no coordinate calculation happens. Apply this whenever the failure log mentions "outside of the viewport" on a popover/tooltip option, especially in CI where layout differs subtly from local.
-- **Action-icon rows below the fold.** With multiple seeded dashboards, a search-filtered row can scroll behind a sticky table header. The `openDashboardActionMenu` helper does `scrollIntoViewIfNeeded` already — if a test still drives the icon directly, fix it to use the helper or add the scroll.

 - **React Query mutations vs page.goto.** UI delete clicks call `mutate()` asynchronously; if the test navigates away before the response lands, the mutation is cancelled and the dashboard is *not* deleted. Wait for the DELETE response and the dialog dismissal explicitly: `page.waitForResponse((r) => r.request().method() === 'DELETE' && /\/dashboards\//.test(r.url()))` plus `await expect(dialog).not.toBeVisible()`.
 - **Monaco editor swallows Escape inside the Import JSON dialog.** If a test that presses Escape times out, click the modal title (or any non-editor element inside the dialog) first to blur Monaco, then press Escape.
-- **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.

+- **Timeouts.** Never add `test.slow()` to a driver: it triples the remaining budget per call and compounds in loops. Use `allowFor(floor)` from `drivers/kit.ts`. Budgets and their measurements are in `tests/e2e/docs/flake-notes.md`.
+- **CI-only failures.** Reproduce with `STRESS=1 CI=1 pnpm test <path>` from `tests/e2e/` before calling it a product bug.
+- **Commits.** Driver fixes and spec fixes go in separate commits (see Commits in `tests/e2e/AGENTS.md`).
 - **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.

 **Quality bar:**
 - Steps must be specific enough that any tester (or the generator agent) can follow without ambiguity.
 - Include negative scenarios — empty state, no-match search, validation errors.
-- Each scenario must own its preconditions and cleanup. **Do not invent cross-file global fixtures** — they break parallel-by-file execution. Suite-level `beforeAll` / `afterAll` *within* a single spec file is fine and is the preferred shape for files with > ~10 scenarios; per-test `try / finally` is fine for smaller specs.
-- Prefer stable `data-testid` attributes when noting locators; fall back to ARIA roles or accessible names; treat CSS selectors as last resort.
+- Each scenario must own its preconditions and cleanup, and assert only on names it seeded. **Never depend on data another spec file created.** Files run in parallel. Pick the seed scope from the Seeding table in [tests/e2e/AGENTS.md](../../tests/e2e/AGENTS.md).
+- Note the `data-testid` for every element a step touches. Where none exists, say so: the generator adds it to the product rather than falling back to roles or CSS (antd internals aside).
 - **Don't pad coverage.** Every TC must catch a regression that would actually ship if the test were missing — a real branch in the source, a real user-visible failure mode. A TC that asserts a hard-coded string is still rendered, or that a button is still a button, adds nothing but maintenance cost: it inflates the suite, slows CI, and trains readers to skim past the directory. Before writing a scenario, ask "what code change would break this?" — if the only answer is "deleting the literal under test," cut it or fold it into a richer scenario as one assertion among many.
 - **Collapse near-duplicates.** Two TCs that differ only in input value (search by title vs search by description, when the underlying code path is the same) should merge into one parameterised scenario unless each input genuinely exercises a distinct branch. Prefer one assertion-rich TC over three thin ones.
 - **Smoke-checks aren't TCs.** "Heading is visible" belongs as the first assertion inside a real scenario, not as its own numbered case.

-### `fixtures/` vs `helpers/` — what goes where
+### The driver kit
 
-These two folders look similar but mean different things:
-
-- **`fixtures/`** holds *Playwright test fixtures* (created via `test.extend({...})`). By the canonical definition, a fixture is "a consistent, predefined set of data, objects, or environmental conditions used to ensure tests run in a stable state" — i.e. setup/teardown that runs *automatically* around each test or worker. `auth.ts` matches: it extends Playwright's `test` with an `authedPage` that's logged-in before every test runs and torn down after. If the only thing in this folder ever is `auth.ts`, that's fine — fixtures are a deliberately small surface.
-- **`helpers/`** holds plain function helpers that you call *explicitly* from a test or hook — they don't extend Playwright's `test`. This covers both behaviour helpers (e.g. `gotoDashboardsList(page)`) and the constants those helpers and the tests both refer to (e.g. `SEARCH_PLACEHOLDER`). Constants live next to the helpers that use them so a single import line in a test covers both.
-- **`testdata/`** holds static data files (typically JSON / YAML) consumed by the helpers — for example, `apm-metrics.json`, a real dashboard payload uploaded through the UI by an importer helper.
-
-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/`.
-
-### Drivers
-
-New suites use a driver rather than loose helpers. A driver is a function that closes over the page and returns the feature's actions and locators. `drivers/kit.ts` turns it into a fixture, so a spec imports one module and never passes a `page` around:
+A spec imports **one** module: its feature's `test` constant. That constant is
+built by composing layers, and each layer adds one named driver to the test
+arguments — so a spec body never handles a `Page`:
 
 ```ts
-import { expect, PATH, test } from '../../drivers/routing';
+import { expect, test } from '../../drivers/alerts';
 
-test('TC-09 RouteTab switches the url', async ({ routing }) => {
-	await routing.goto(PATH.metricsSummary);
-	await expect(routing.activeRouteTab(PATH.metricsSummary)).toBeVisible();
+test('TC-01 seeded rules render', async ({ alerts, alertList }) => {
+  await alerts.list.goto({ search: alertList.namePrefix });
+  await expect(alerts.list.rows()).toHaveCount(10);
 });
 ```
 
-- `driver(name, build)` adds a test-scoped fixture built on `authedPage`.
-- `seeded(name, open, close)` adds a worker-scoped seed. `open` and `close` run on a throwaway admin page.
-- A driver reuses helpers by calling them, never by reaching for another fixture.
-- `drivers/` is AI-owned: coding agents generate and maintain it with the specs, and `.gitattributes` collapses it in diffs.
-
-### 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>/`.
+- **`drivers/kit.ts`** holds the composition primitives. `driver(name, build)`
+  binds a factory to the authenticated page; `seeded(name, open, close)` seeds
+  data once per worker on a throwaway admin page and tears it down after;
+  `allowFor(floor)` raises the test timeout to a floor and never lowers it.
+  `test.slow()` is banned in drivers, because it compounds when called in a loop.
+- **`drivers/<feature>.ts`** (or `drivers/<feature>/`) exports the feature's
+  driver, its layers, and the composed `test`. A driver is a plain function
+  returning an object of closures — no classes, and no `page` parameter on
+  anything a spec calls.
+- **Shared drivers** — `tanstack.ts` (the table), `querysearch.ts` (the
+  expression editor), `antd.ts` (select primitives), `console.ts`, `api.ts`,
+  `storage.ts` — are composed into feature drivers by direct call, not by
+  reaching for another fixture.
+- **`drivers/` is AI-owned**: coding agents generate and maintain it with the
+  specs, and `.gitattributes` collapses it in diffs.
+- **`testdata/`** and any `__generated__/` directory hold transcribed data. Both
+  are marked `linguist-generated`; something in the suite re-derives them at
+  runtime, so a stale value fails loudly rather than silently.
 
 **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.
+- **worker scope** — shared across a worker. Use for read-only data; it pays the
+  setup cost once per worker instead of once per test. Playwright builds them
+  lazily, so a spec that never destructures a seed never pays for it.
+- **suite scope**: a dataset only one file uses. Seed it in `test.beforeAll`
+  through `onAdminPage(browser, …)`, since `authedPage` is test-scoped.
 
-**The alerts pattern** (`fixtures/alerts/`) demonstrates extending fixtures:
+### Which layer does this test belong to?
 
-```
-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)
-```
+Four layers run against this codebase, in cost order: **jest → Storybook + msw →
+pytest integration → Playwright**. Before writing an E2E, check the cheaper
+three. [`tests/e2e/AGENTS.md`](../../../tests/e2e/AGENTS.md) has the full rule;
+the short version:
 
-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."
+- A pure function, a reducer, a config literal or a component's own behaviour is
+  a **jest** test. Most containers under `frontend/src/container/` already have
+  one.
+- A rendered state that needs no backend (empty, error, loading) is a
+  **Storybook** story or a jest test with a fixed mock.
+- Anything the **API** does — ordering, pagination, filter semantics, validation,
+  roll-ups — is a pytest integration test, and for infra monitoring and alert
+  evaluation it very likely already exists. Grep `tests/integration/` first.
+- An **E2E** is for a real response reaching a real DOM: URL and history, write
+  paths that must persist, cross-page navigation, and one seeded proof per
+  surface.
 
 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.
 2. **Test titles use `TC-NN`**: `test('TC-01 alerts page — tabs render', ...)`. Preserves ordering at a glance and maps to external coverage tracking.
-3. **UI-first**: drive flows through the UI. Playwright traces capture every BE request/response the UI triggers, so asserting on UI outcomes implicitly validates BE contracts. Reach for direct `page.request.*` only when the test's *purpose* is asserting a response contract (use `page.waitForResponse` on a UI click) or when a specific UI step is structurally flaky (e.g. Ant DatePicker calendar-cell indices) — and even then try UI first.
-4. **Self-contained state**: each spec seeds its own data and cleans up at suite teardown. The pytest harness creates a fresh stack with **zero** dashboards / alerts / etc. — never assume pre-existing data. Two patterns work:
-    - **Per-test seed + cleanup in `try / finally`** — small specs where each test owns its data.
-    - **Suite-level seed + `afterAll` teardown** — preferred for larger specs. Each `createDashboard(...)` call adds the resulting ID to a module-level `Set<string>`, and one `test.afterAll(...)` deletes everything in the set. See `tests/e2e/tests/dashboards/list.spec.ts` for the full pattern. `test.beforeAll` / `test.afterAll` cannot use `authedPage` directly (it's test-scoped); use `newAdminContext(browser)` from `helpers/auth.ts` instead — it performs one fresh login per suite hook.
-5. **Seed via API when the UI flow is multi-step or brittle.** The frontend stores its JWT in `localStorage` under `AUTH_TOKEN`; `page.request.*` inherits the auth fixture's storage state. A typical pattern:
-    ```ts
-    const token = await page.evaluate(
-      () => (globalThis as any).localStorage.getItem('AUTH_TOKEN') || '',
-    );
-    await page.request.post('/api/v1/dashboards', {
-      data: { title: 'my-name', uploadedGrafana: false },
-      headers: { Authorization: `Bearer ${token}` },
-    });
-    ```
-    This is faster and more reliable than a multi-step UI seed. Reach for the UI flow only when the test's *purpose* is asserting that flow.
-6. **Reusable static data lives in `tests/e2e/testdata/`.** For example, `apm-metrics.json` is a real dashboard payload that `importApmMetricsDashboardViaUI` (in `helpers/dashboards.ts`) uploads through the actual Import JSON UI flow to seed a richly-tagged dashboard for search/list tests.
+3. **UI-first**: drive flows through the UI. Playwright traces capture every BE request/response the UI triggers, so asserting on UI outcomes implicitly validates BE contracts. To assert a write, attach `page.waitForResponse` before the click, then reload and re-read from the server.
+4. **Self-contained state**: each spec seeds its own data, scopes its assertions to the names it seeded, and cleans up. The pytest harness creates a fresh stack with **zero** dashboards / alerts / etc. Names carry the worker index, so parallel workers never collide. Pick the scope from the list above.
+5. **Seed through the kit when the UI flow is not under test.** `apiDriver(page)` (`drivers/api.ts`) creates control-plane objects with the session's token, and the seeder takes telemetry. The JWT lives in `localStorage`, so a spec never improvises with `page.request.*`. Feature drivers wrap both (`dashboards.create`, `alerts.seed.threshold`).
+6. **Reusable static data lives in `tests/e2e/testdata/`.** For example, `traces/large-trace.json` is POSTed to the seeder by `drivers/traces.ts`. Infra monitoring reads the integration suite's fixtures through `seedDataset` (`drivers/infra/seed.ts`) instead of keeping a copy, and asserts on what it returned.
+7. **Locate by testid, in the driver.** A missing testid is added to the product in the same change. Role, label and CSS lookups are a stopgap, converted as that code is touched; antd internals (`.ant-select-dropdown`) are the exception, since the markup is not ours.
 
 ## How to write an E2E test?
 
 Create a new file `tests/e2e/tests/alerts/smoke.spec.ts`:
 
 ```typescript
-import { test, expect } from '../../fixtures/auth';
+import { ALERT_LIST_PAGE_SIZE, expect, test } from '../../drivers/alerts';
 
-test('TC-01 alerts page — tabs render', async ({ authedPage: page }) => {
-  await page.goto('/alerts');
-  await expect(page.getByRole('tab', { name: /alert rules/i })).toBeVisible();
-  await expect(page.getByRole('tab', { name: /configuration/i })).toBeVisible();
+test('TC-01 seeded rules render and paginate', async ({ alerts, alertList }) => {
+  await alerts.list.goto({ search: alertList.namePrefix });
+  await expect(alerts.list.table.totalCount()).toContainText(`of ${alertList.count}`);
+  await expect(alerts.list.rows()).toHaveCount(ALERT_LIST_PAGE_SIZE);

 ## Agents
 
 Three Claude agents in `.claude/agents/` accelerate writing and maintaining E2E specs:
 
 - **`playwright-test-planner`** — explores a feature in a real browser plus the local frontend source and writes a test plan as a scratch markdown file (under `tests/e2e/specs/`, which is gitignored — plans are working artifacts for the generator, not committed docs).
-- **`playwright-test-generator`** — converts a test plan into Playwright spec files under `tests/e2e/tests/<feature>/`. Drives each scenario through MCP browser tools and emits TC-NN-titled tests using the `authedPage` fixture and the API-seed pattern.
+- **`playwright-test-generator`** — converts a test plan into Playwright spec files under `tests/e2e/tests/<feature>/`. Drives each scenario through MCP browser tools and emits TC-NN-titled tests on the feature's driver, adding the driver methods and seeds the plan needs.
 - **`playwright-test-healer`** — runs failing specs, debugs them with snapshots / console / network introspection, and edits the spec to fix selector drift, timing, or state-leak issues.
 
 The agents rely on the Playwright-test MCP server (`mcp__playwright-test__*` tools). Configure it in your Claude MCP settings; the permission allowlist lives in [.claude/settings.local.json](../../../.claude/settings.local.json).

 - **Always use the `--reuse` flag** when setting up the E2E stack. `--with-web` adds a ~4 min frontend build on a cold start; later builds are incremental.
 - **Changed backend or frontend code? Re-run the setup command** — it passes `--rebuild`, swapping the SigNoz container for one built from your current sources while the rest of the stack stays up.
 - **Don't teardown before setup.** `--reuse` correctly handles partially-set-up state, so chaining teardown → setup wastes time.
-- **Prefer UI-driven flows.** Playwright captures BE requests in the trace; a parallel `fetch` probe is almost always redundant. Drop to `page.request.*` only when the UI can't reach what you need.
+- **Prefer UI-driven flows.** Playwright captures BE requests in the trace; a parallel `fetch` probe is almost always redundant. Seed through the kit, never with `page.request.*`.
 - **Use `page.waitForResponse` on UI clicks** to assert BE contracts — it still exercises the UI trigger path.
 - **Title every test `TC-NN <short description>`** — keeps the suite navigable and reportable.
 - **Split by resource, not by regression suite.** One spec per feature resource; cross-resource junction concerns (cascade-delete, linked-edit) get their own file.
-- **Use short descriptive resource names** (`alerts-list-rule`, `labels-rule`, `downtime-once`) — no timestamp disambiguation. Each test owns its resources and cleans up in `try/finally`.
+- **Name resources by what they are, plus the worker index** (`e2e-alert-list-w${workerIndex}-${Date.now()}`). Six workers share one stack, so assert only on names you seeded.
 - **Never commit `test.only`** — a pre-commit check or CI runs with `forbidOnly: true`.
 - **Prefer explicit waits over `page.waitForTimeout(ms)`.** `await expect(locator).toBeVisible()` is always better than `waitForTimeout(5000)`.
 - **Unique test names won't save you from shared-tenant state.** When two tests hit the same list page, either serialize (`describe.configure({ mode: 'serial' })`) or isolate cleanup religiously.
+- **Green locally, red on CI?** Run `STRESS=1 CI=1 pnpm test <path>` (4x CPU throttle, 2 workers, 2 retries) before filing a product bug.
+- **Commit drivers apart from specs.** One concern per commit; see [Commits](#commits).
 - **Artifacts go to `tests/e2e/artifacts/`** — HTML report at `artifacts/html`, traces at `artifacts/results/<test>/`. All gitignored; archive the dir in CI.
