@@ -131,7 +131,7 @@ A `LogicalField` is one meaning: one name, context, and data type, backed by one
 The resolution order is the same for every storage, in the filter and in every select field, group by, order by, and aggregation:
 
 1. **Own context.** A key under one of the storage's own contexts (`span.x`, `log.x`) matches its own context first, then a column the storage knows under that context. Only when both miss does it look up as if it had no context. `span.http.method` then corrects to the attribute. Strict contexts (`resource.`, `attribute.`, `scope.`, `body.`) are kept as written.
-2. **Matches.** The metadata keys under the key's spellings, grouped into families when the flag is on. Each combination of context and data type is one interpretation. A key written as `exact(key)` in an expression, or a structured key with `fieldResolution: exact`, reads its own spelling alone.
+2. **Matches.** The metadata keys under the key's spellings, grouped into families when the flag is on. Each combination of context and data type is one interpretation.
 3. **Ambiguity.** A filter settles several interpretations by resource over attribute, with a warning. A select field, group by, order by, or aggregation keeps every interpretation in metadata order and folds them, so it shows the value wherever it is.
 4. **Intrinsic column first**, bare keys only. A column every row has leads the list. Metadata can report the column, or the storage's `Fallback` can. When only `Fallback` knows the column, its key carries the data type the column reads as (`querybuilder.ColumnDataType`). A same-named metadata key of a contradicting type then drops, and a time column merges none. When metadata reports the column too, every match reads. A metadata gap degrades to the correct column, never to a corrupt metadata key.
 5. **Fallback.** With no match, the storage's fallback keys for the key. When the storage ignores unknown keys (a side query whose main query owns the error), the key is `Skipped`. Otherwise a key nothing can serve is an error with suggestions. The not-found warning fires only when every fallback key is a guess, that is, none of them is always present.

 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:
+
+```ts
+import { expect, PATH, test } from '../../drivers/routing';
+
+test('TC-09 RouteTab switches the url', async ({ routing }) => {
+	await routing.goto(PATH.metricsSummary);
+	await expect(routing.activeRouteTab(PATH.metricsSummary)).toBeVisible();
+});
+```
+
+- `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>/`.
