fix(alerts): keep configuration sidebar item weight constant when active (#13432)

#### Description

- Configuration sidebar items (Notification Channels, Routing Policies,
Planned Downtime) no longer turn bold when selected; only the colour
changes, so the label no longer shifts.

Closes: https://github.com/SigNoz/pulse-pod/issues/693

Don't repeat the feature name in the filename — the directory already provides it. `dashboards/list/search.spec.ts`, not `dashboards/list/dashboards-list-search.spec.ts`.
-- **Drivers first.** New specs import `test`, `expect` and constants from one driver module in [tests/e2e/drivers/](../../tests/e2e/drivers/) and receive the feature's driver as a fixture. A spec never passes `page` around.
+- **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`.

   ```
   - A driver is a function closing over the page that returns `Locator` getters and async actions. Actions wait inside themselves (e.g. `run()` pairs the click with `waitForResponse(/query_range/)`), so specs don't.
   - `driver(name, build, dispose?)` in `drivers/kit.ts` makes it a test-scoped fixture on `authedPage`; `dispose` deletes what it seeded. `seeded(name, open, close)` makes a worker-scoped seed.
-  - Layers compose: `withNewPanel(withEditor(panelsTest))`. Extend the closest existing driver instead of starting a parallel one.
-  - When no driver covers the feature, add `drivers/<feature>.ts` with the spec. Locators live in the driver, not the spec. `drivers/` is AI-owned: keep the banner, and change a driver only alongside a spec that needs it.
   - Read [tests/e2e/tests/dashboards/editor/query.spec.ts](../../tests/e2e/tests/dashboards/editor/query.spec.ts) and [drivers/panel-editor.ts](../../tests/e2e/drivers/panel-editor.ts) for the canonical shape.
-- **Plain auth fixture** only for a spec no driver fits: import `test` and `expect` from `'../../fixtures/auth'` (never `@playwright/test`) and use the `authedPage` fixture (the admin, the only user the bootstrap seeds).
-- **Extended fixtures:** older suites import domain fixtures that extend `auth`. See [docs/contributing/tests/e2e.md](../../docs/contributing/tests/e2e.md).
-  - `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 resources. Cleanup shapes, in order of preference:
-  - **A driver's `dispose`** — the driver tracks what it seeded and deletes it after the test (`dashboards.seed(...)` in `drivers/dashboards.ts`). The spec has no cleanup code.
-  - **A worker-scoped `seeded(...)` layer** — read-only data shared by a worker's tests.
-  - **Per-test `try / finally`** or **suite-level `afterAll` with an id registry** — specs without a driver. Suite hooks can't see `authedPage`; use `newAdminContext(browser)` from `helpers/auth.ts`.
-- **Golden telemetry is pre-seeded.** `bootstrap/global.setup.ts` loads logs, traces and metrics over the last 6h (constants in `GOLDEN`, `helpers/dashboard-spec.ts`). Query within ≤ 6h and assert structure (series, rows, request payload), never exact counts: per-test seeds from parallel workers land in the same tenant. Seed missing shapes through the seeder with unique service names (`helpers/alerts/seeding.ts`).
-- **Reuse helpers from `tests/e2e/helpers/`** inside drivers. Don't reinvent:
-  - [`helpers/common.ts`](../../tests/e2e/helpers/common.ts) — `authToken`, `watchConsole`, `collectRequests`, `requestUrl`, `seederUrl`.
-  - [`helpers/auth.ts`](../../tests/e2e/helpers/auth.ts) — `newAdminContext(browser)`.
-  - [`helpers/query-range-mock.ts`](../../tests/e2e/helpers/query-range-mock.ts) — `query_range` mocks for error / no-data / warning / loading states only; install before `goto`.
-- **Seed via API when the UI flow is multi-step or brittle**, through the driver (`dashboards.seed`, `seedAndOpen`, `seedAndEdit`). `page.request.*` does **not** auto-attach `Authorization`; drivers add `authToken(page)`.
-- **Static payloads live in [tests/e2e/testdata/](../../tests/e2e/testdata/)** (`dashboards/panels.ts`, `traces/large-trace.json`).
-- **Resource names:** short and descriptive, no timestamps. Where parallel workers share a list, add a random suffix as `uniqueName` in `drivers/dashboard-list.ts` does.
+- **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.seed`, `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.
+- **Golden telemetry is pre-seeded.** `bootstrap/global.setup.ts` loads logs, traces and metrics over the last 6h (constants in `GOLDEN`, `drivers/dashboard-spec.ts`). Query within ≤ 6h and assert structure (series, rows, request payload), never exact counts.
+- **`query_range` mocks** in [`drivers/query-range-mock.ts`](../../tests/e2e/drivers/query-range-mock.ts) are for error / no-data / warning / loading states only; install before `goto`.
+- **Reusable payloads live in [tests/e2e/testdata/](../../tests/e2e/testdata/)** (traces and logs POSTed to the seeder, `dashboards/panels.ts`). 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)).

 # Repo-specific signals
 
-- **Reuse drivers and helpers before adding new code.** [`tests/e2e/drivers/`](../../tests/e2e/drivers/) holds the per-feature seed, cleanup, navigation and action methods (`kit.ts` explains `driver` / `seeded`); [`helpers/common.ts`](../../tests/e2e/helpers/common.ts) and [`helpers/auth.ts`](../../tests/e2e/helpers/auth.ts) the plain plumbing. Prefer them over re-inlining auth/login/POST code 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. Add `scrollIntoViewIfNeeded` before the click, in the driver action.
+- **Action-icon rows below the fold.** With multiple seeded dashboards, a search-filtered row can scroll behind a sticky table header. Add `scrollIntoViewIfNeeded` before the click, in the driver action (`dashboardList.openRowMenu(name)`).
 - **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.** List controls and the `new-dashboard-cta` testid are absent in zero-state. A timeout on those usually means the workspace was empty — seed first via `dashboards.seed(...)`.
-- **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/common.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.
+- **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 `dashboards.seed(...)`.
+- **Auth.** `tests/e2e/drivers/auth.ts` logs in once per worker and caches `storageState` (localStorage with `AUTH_TOKEN`). For API-driven seeding and cleanup use `apiDriver(page)` from `drivers/api.ts`, which attaches the header for you. Never re-implement login.
+- **Seeds.** Feature seeds are layers on the feature's `test`, e.g. `alertList`, `ownedRules` and `resolvedHistory` in `drivers/alerts/seeds.ts`. When a test fails on missing data, check which seed it destructures and whether it scopes to that seed's names.
+- **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.

A driver is a fixture exposing the feature's locators and actions, including API seeding that cleans itself up (`dashboards.seed(...)`). When one covers the feature, write steps in terms of its actions by name so the generator reuses them. When none does, say so: the generator adds one.
-   - [tests/e2e/helpers/](../../tests/e2e/helpers/) holds plain helpers: `common.ts` (`authToken`, `watchConsole`, `collectRequests`, `seederUrl`), `auth.ts` (`newAdminContext`), `query-range-mock.ts` (mock `query_range` for error, no-data, warning and loading states only).

+   - **Storybook + msw** — a rendered state that needs no backend (empty, error,

+     (`tests/integration/tests/inframonitoring/`, 123 test functions) and for
+     alert evaluation (`tests/integration/tests/alerts/`) the answer is usually
+     that it already exists.
+   - **E2E** — only when a real response has to reach a real DOM: URL and
+     history, a write path that must persist, cross-page navigation, one seeded
+     proof per surface.

 **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. Prefer a driver's self-cleaning seed (`dispose`) or worker-scoped `seeded(...)` layer; without a driver, suite-level `beforeAll` / `afterAll` within one spec file or per-test `try / finally` both work.
-- 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); a driver's self-cleaning seed (`dispose`) or a worker-scoped `seeded(...)` layer covers most cases.
+- 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.

+# Frontend state
+
+Pick the store by what the state is. Never add Redux or React Context for shared state; to move existing Redux or Context state, use the `migrate-state-management` skill ([`frontend/.claude/skills/migrate-state-management/SKILL.md`](../../frontend/.claude/skills/migrate-state-management/SKILL.md)).
+
+| State | Use | Never |
+|---|---|---|
+| Server / API data | React Query, generated hooks from `src/api/generated` | a copy in Redux, Context or Zustand |
+| Shareable: filters, time range, selection, page | nuqs (`useQueryState` with a parser) | Redux, Context, hand-parsed `useSearchParams` |
+| Global client state | a small Zustand store per domain | Redux, Context |
+| One component's UI state | `useState` / `useReducer` | any store |
+
+## Server state
+
+- Expose a query through a hook that returns its result plus memoized derived values. Never dispatch a response into another store.
+- **The query key holds every value the request reads.** A field change that alters the request (name, context, data type) must change the key; a lossy signature serves stale rows.
+
+## URL state
+
+- Keep the URL small (Chrome trims near 2k characters). No large datasets, no sensitive data.
+- **A rewrite touches only the params it owns.** Repairing or normalising one param keeps the rest (`activeLogId`, pagination) as they were.
+- **Links carry the current time range.** A row link, "open in new tab" and "copy link" land on the same period as an in-app click.
+- **A preset read from the URL applies once.** A later user change or reset must not re-apply it.
+
+## Zustand
+
+- One `create()` per module; split a large store into slice factories combined in that one `create()`.
+- Always read through a selector: `useDashboardStore((s) => s.isDashboardLocked)`, never `useDashboardStore()`.
+- Update only through `set`; never mutate state. State fields before actions in the store object.
+- Hooks never call `useStore.getState()` (`signoz/no-zustand-getstate-in-hooks`); export standalone actions instead.
+
+## Local and form state
+
+- **Editable state starts from saved data once.** Initialise the form from the saved value, then let the user own it; never re-derive it from saved data on each render.
+- **A mode switch owns its in-flight work.** While a request from one mode runs, disable the switch or drop the result when the mode changes, so it can't close or overwrite the new mode.

+Examples and the harness API live in [`frontend/src/tests/README.md`](../../frontend/src/tests/README.md).
+
+- **Import from the harness.** `render`, `screen`, `userEvent`, `waitFor` and the rest come from `tests/test-utils`, never from `@testing-library/react`. The harness mounts the router, React Query, Redux, app context and preferences. When it can't do what a test needs, extend `tests/test-utils` instead of importing around it.
+- **Find elements by test ID.** Query with `getByTestId`/`findByTestId` on the `data-testid` or `testId` the component exposes, and add one to the component when it has none. Fall back to role or text only for markup the app doesn't own. A test ID matches exactly one element and survives copy and markup changes; `getByRole` computes the accessibility tree on every call and is the slowest query.
+- **Interact like a user.** `const user = userEvent.setup({ pointerEventsCheck: 0 })`, then an awaited `user.click`, `hover`, `keyboard` or `type`. `fireEvent` only for events `userEvent` has no equivalent for: scroll, resize, setting `scrollTop`.
+- **Fake timers per test only**, for debounce or throttle, with `userEvent.setup({ advanceTimers: (ms) => jest.advanceTimersByTime(ms) })`. Never global.
+- **Network through MSW.** The global server runs for every test; override per test with `server.use(...)` from `mocks-server/server`. Large fixtures go in `mocks-server/__mockdata__`.
+- **Router through the harness.** Pass `initialRoute`/`routePath` to `render` and assert with `getCurrentLocation()` from `lib/router/navigation`. Never mock `react-router`, `react-router-dom` or `lib/history`; when a test can't render at a route, use the `lib/router` spies in `tests/router-mocks`.
+- **Mock only business boundaries.** Local `jest.mock` for API modules, custom hooks and domain components. Never re-mock what the harness provides or what `jest.config.ts` maps (`uplot`, `@signozhq/icons`, `useSafeNavigate`, `logEvent`).
+- **Type mocks and fixtures.** `jest.mocked(fn)` for module mocks, `jest.fn() as jest.MockedFunction<T>` for a standalone mock you configure or assert on. Fixtures carry their real type, from `src/api/generated` where it exists. No `any`, no `as unknown as`. An inline `onX={jest.fn()}` on a typed prop that is never asserted needs no annotation.
+- **A test fails without its change.** Revert the change, or break the line under test, and run the test before you finish: it must fail. Assert the specific outcome (exact text, request payload, call arguments), never only that an element exists.
+- **No limit on tests per file.** Split a file when it mixes unrelated behaviour, not to hit a count.

+`ILog.body` is `string | ILogBody`. On `use_json_body` tenants the API sends an object, and the collector wraps a plain-string body into `{ message }`. Every read goes through `frontend/src/lib/logs/logBody.ts`.
+
+- **Read with a getter, never directly.** `getBodyDisplay` for a list cell or a log line, `getBodyMessage` for the drawer header. Both accept `undefined` and collapse a `{message}`-only object to its message.
+- **Never cast or stringify a body inline.** No `as string`, no `String(log.body)`, no `JSON.stringify(log.body)`, no `typeof body === 'string' ? … : …` outside the module. The v5 converter collapses `{ message }` once with `extractOnlyMessageBody`; live logs and the dashboard list panel skip the converter, so their rows carry the raw object and only a getter renders them right.
+- **Resolve a selected field with `getLogFieldValue`** from `lib/logs/flatLogData.ts`, so a `body.<key>` column works on both string and object bodies. An object value renders as JSON and is not offered as an add-to-query filter.
+- **The drawer tree and field lookup are the only places that use the raw value.** Everything else renders a string from a getter.
+- **Review check.** A raw body value used outside a getter call, `extractOnlyMessageBody` in the converter, `flatLogData.ts` and `LogDetailedView/utils.tsx` is a finding.

-### `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. `gotoLogsExplorer(page)`) and the constants those helpers and the tests both refer to (e.g. `LINKED_ROW_CLASS`). 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, `traces/large-trace.json`, a real trace the trace-details helpers seed.
-
-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, dispose?)` adds a test-scoped fixture built on `authedPage`. `dispose` runs after the test on the same page, so a driver can delete what it seeded.
-- `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, dispose?)`
+  binds a factory to the authenticated page, and `dispose` runs after the test
+  on the same page so a driver can delete what it seeded; `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. Patterns, in order of preference:
-    - **Driver `dispose`** — the driver tracks what it seeded and deletes it after the test, so the spec has no cleanup code. See `dashboards.seed(...)` in `tests/e2e/drivers/dashboards.ts`.
-    - **Per-test seed + cleanup in `try / finally`** — small specs without a driver, where each test owns its data.
-    - **Suite-level seed + `afterAll` teardown** — larger specs without a driver. One `test.afterAll(...)` deletes everything the suite seeded. See `tests/e2e/tests/llm-o11y/llm-pricing.spec.ts`. `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, `traces/large-trace.json` is a real trace that `loadLargeTrace` (in `helpers/trace-details.ts`) seeds for the trace-details 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.seed`, `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);
 });
 ```
 
-The `authedPage` fixture (from `tests/e2e/fixtures/auth.ts`) gives you a `Page` whose browser context is already authenticated as the admin user. First use per worker triggers one login; the resulting `storageState` is held in memory and reused for later requests.

 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).

-# State Management: React Query, nuqs, Zustand
-
-Use the following stack. Do **not** introduce or recommend Redux or React Context for shared/global state.
-
-## Server state → React Query
-
-- **Use for:** API responses, time-series data, caching, background refetch, retries, stale/refresh.
-- **Do not use Redux/Context** to store or mirror data that comes from React Query (e.g. do not dispatch API results into Redux).
-- Prefer generated React Query hooks from `frontend/src/api/generated` when available.
-- Keep server state in React Query; expose it via hooks that return the query result (and optionally memoized derived values). Do not duplicate it in Redux or Context.
-
-```tsx
-// ✅ GOOD: single source of truth from React Query
-export function useAppStateHook() {
-  const { data, isError } = useQuery(...)
-  const memoizedConfigs = useMemo(() => ({ ... }), [data?.configs])
-  return { configs: memoizedConfigs, isError, ... }
-}
-
-// ❌ BAD: copying React Query result into Redux
-dispatch({ type: UPDATE_LATEST_VERSION, payload: queryResponse.data })
-```
-
-## URL state → nuqs
-
-- **Use for:** shareable state, filters, time range, selected values, pagination, view state that belongs in the URL.
-- **Do not use Redux/Context** for state that should be shareable or reflected in the URL.
-- Use [nuqs](https://nuqs.dev/docs/basic-usage) for typed, type-safe URL search params. Avoid ad-hoc `useSearchParams` encoding/decoding.
-- Keep URL payload small; respect browser URL length limits (e.g. Chrome ~2k chars). Do not put large datasets or sensitive data in query params.
-
-```tsx
-// ✅ GOOD: nuqs for filters / time range / selection
-const [timeRange, setTimeRange] = useQueryState('timeRange', parseAsString.withDefault('1h'))
-const [page, setPage] = useQueryState('page', parseAsInteger.withDefault(1))
-
-// ❌ BAD: Redux/Context for shareable or URL-synced state
-const { timeRange } = useContext(SomeContext)
-```
-
-## Client state → Zustand
-
-- **Use for:** global/client state, cross-component state, feature flags, complex or large client objects (e.g. dashboard state, query builder state).
-- **Do not use Redux or React Context** for global or feature-level client state.
-- Prefer small, domain-scoped stores (e.g. DashboardStore, QueryBuilderStore).
-
-### Zustand best practices (align with eslint-plugin-zustand-rules)
-
-- **One store per module.** Do not define multiple `create()` calls in the same file; use one store per module (or compose slices into one store).
-- **Always use selectors.** Call the store hook with a selector so only the used slice triggers re-renders. Never use `useStore()` with no selector.
-
-```tsx
-// ✅ GOOD: selector — re-renders only when isDashboardLocked changes
-const isLocked = useDashboardStore(state => state.isDashboardLocked)
-
-// ❌ BAD: no selector — re-renders on any store change
-const state = useDashboardStore()
-```
-
-- **Never mutate state directly.** Update only via `set` or `setState` (or `getState()` + `set` for reads). No `state.foo = x` or `state.bears += 1` inside actions.
-
-```tsx
-// ✅ GOOD: use set
-increment: () => set(state => ({ bears: state.bears + 1 }))
-
-// ❌ BAD: direct mutation
-increment: () => { state.bears += 1 }
-```
-
-- **State properties before actions.** In the store object, list all state fields first, then action functions.
-- **Split into slices when state is large.** If a store has many top-level properties (e.g. more than 5–10), split into slice factories and combine with one `create()`.
-
-```tsx
-// ✅ GOOD: slices for large state
-const createBearSlice = set => ({ bears: 0, addBear: () => set(s => ({ bears: s.bears + 1 })) })
-const createFishSlice = set => ({ fish: 0, addFish: () => set(s => ({ fish: s.fish + 1 })) })
-const useStore = create(set => ({ ...createBearSlice(set), ...createFishSlice(set) }))
-```
-
-- **In projects using Zustand:** add `eslint-plugin-zustand-rules` and extend `plugin:zustand-rules/recommended` to enforce these rules automatically.
-
-## Local state → React state only
-
-- **Use useState/useReducer** for: component-local UI state, form inputs, toggles, hover state, data that never leaves the component.
-- Do not use Zustand, Redux, or Context for state that is purely local to one component or a small subtree.
-
-## Summary
-
-| State type        | Use              | Avoid              |
-|-------------------|------------------|--------------------|
-| Server / API      | React Query      | Redux, Context     |
-| URL / shareable   | nuqs             | Redux, Context     |
-| Global client     | Zustand          | Redux, Context     |
-| Local UI          | useState/useReducer | Zustand, Redux, Context |

-
-# Testing Conventions
-
-## Imports
-
-Always import from the test harness, never directly from `@testing-library/react`:
-
-```ts
-import { render, screen, userEvent, waitFor } from 'tests/test-utils';
-import { server, rest } from 'mocks-server/server';
-```
-
-## Router
-
-Use the built-in router in `render`:
-
-```ts
-render(<Page />, undefined, { initialRoute: '/traces-explorer' });
-```
-
-Only mock `useLocation` / `useParams` if the test depends on their values.
-
-## MSW
-
-Global MSW server runs automatically. Override per-test:
-
-```ts
-server.use(
-  rest.get('*/api/v1/foo', (_req, res, ctx) =>
-    res(ctx.status(200), ctx.json({ ok: true })))
-);
-```
-
-Keep large response fixtures in `mocks-server/__mockdata_`.
-
-## Interactions
-
-- Prefer `userEvent` for real user interactions (click, type, select, tab).
-- Use `fireEvent` only for low-level events not covered by `userEvent` (e.g., scroll, resize). Wrap in `act(...)` if needed.
-- Always `await` interactions:
-
-```ts
-const user = userEvent.setup({ pointerEventsCheck: 0 });
-await user.click(screen.getByRole('button', { name: /save/i }));
-```
-
-## Timers
-
-No global fake timers. Per-test only, for debounce/throttle:
-
-```ts
-jest.useFakeTimers();
-const user = userEvent.setup({ advanceTimers: (ms) => jest.advanceTimersByTime(ms) });
-await user.type(screen.getByRole('textbox'), 'query');
-jest.advanceTimersByTime(400);
-jest.useRealTimers();
-```
-
-## Queries
-
-Prefer accessible queries: `getByRole` > `findByRole` > `getByLabelText` > visible text > `data-testid` (last resort).
-
-## Anti-patterns
-
-- Never import from `@testing-library/react` directly
-- Never use global fake timers
-- Never wrap `render` in `act(...)`
-- Never mock infra dependencies locally (router, react-query)
-- Limit to 3-5 focused tests per file

-# Mock Strategy
-
-## Use Global Mocks For
-
-High-frequency dependencies (20+ test files):
-- Core infrastructure: react-router-dom, react-query, antd
-- Browser APIs: ResizeObserver, matchMedia, localStorage
-- Utility libraries: date-fns, lodash
-
-Available global mock files (from jest.config.ts):
-- `uplot` -> `__mocks__/uplotMock.ts`
-
-## Use Local Mocks For
-
-- Business logic dependencies (API endpoints, custom hooks, domain components)
-- Test-specific behavior (different data per test, error scenarios, loading states)
-
-## Decision Tree
-
-```
-Used in 20+ test files?
-  YES -> Global mock
-  NO  -> Business logic or test-specific?
-    YES -> Local mock
-    NO  -> Consider global if usage grows
-```
-
-## Correct Usage
-
-```ts
-// Global mocks are already available - just import
-import { useLocation } from 'react-router-dom';
-
-// Local mocks for business logic
-jest.mock('../api/tracesService', () => ({
-  getTraces: jest.fn(() => mockTracesData),
-}));
-```
-
-## Anti-patterns
-
-```ts
-// Never re-mock globally mocked dependencies locally
-jest.mock('react-router-dom', () => ({ ... }));
-
-// Never put test-specific data in global mocks
-jest.mock('../api/tracesService', () => ({ getTraces: jest.fn(() => specificTestData) }));
-```

-const mockProps: ComponentProps = {
-  title: 'Test',

-For all frontend implementation work in this repository:
-
-- Always use UI primitives/components from `@signozhq/ui`.
-- Always use icons from `@signozhq/icons`.
