chore(querybuilder): compile every signal through one storage contract

Each signal had its own copy of name resolution, the guard rule, and the
column renderer, and each copy made its own choices. The semantic
convention families made the differences visible: the same family fold
had to be written seven times, and the guards did not agree.

A storage now answers only what the compiler cannot know: one read per
field key (the bare SQL, the membership test in both polarities, what an
absent row reads, and whether the read keeps its type or filters only),
the fallback for a key metadata does not report, its traits, and one
override for a storage with its own condition language. Resolution, the
filter condition, and the column expression live in querybuilder
and are written one time.

- Storage replaces FieldMapper and ConditionBuilder for traces, logs,
  metrics, audit, rule state history, the resource fingerprint, and the
  related-values metadata.
- Absent says how a field key reads when a row does not carry it, and
  every guard derives from it. A sentinel read takes the exists guard on
  positive operators and in select fields, group by, order by, and
  aggregations. A NULL read and a table
  column take none. A declared keyless contract (metrics labels, rule
  state labels) takes none.
- QueryInfo carries the org, the time range, the signal, the queried
  metric, and the query-path flags, evaluated one time per builder stage.
- LogicalField carries ValueMaps, so a family member's stored vocabulary
  translates to the current one in every read.
- The not-found warning fires only when every fallback key is a guess.
  A key under a signal's own context matches that context first, then
  resolves as if it had no context.

Three results change, because the one guard rule contradicts the old
SQL:

- A table column takes no guard in the group by, order by, and
  aggregation-argument stages. Zero-duration spans enter percentiles and
  averages, and an empty severity is its own group, not the NULL group.
- A scope map attribute takes the default exists guard in logs and
  audit, like an attribute; `scope.x = ''` no longer matches every row
  without the key.
- An audit raw select reads NULL for an absent map attribute, like logs
  and traces, instead of the empty string.

+description: Explore a SigNoz page, map the endpoints, states and query params it has, then write its Storybook page story with control-driven msw mocks that reach every state. Use when asked to create, extend or review a Storybook story for a page under frontend/src/pages, to add controls to an existing page story, or to write defineStoryMocks handlers and mock data for a page.
+---
+
+# SigNoz page stories
+
+A page story renders the real page inside the real app shell against msw, and its
+controls panel can reach every state the page has. The panel is the deliverable,
+not the story list.
+
+`frontend/src/storybook/README.md` is the API surface (providers, parameters,
+control builders, module mocks, navigation). Read it first; this skill is the
+process on top of it.
+
+## Workflow
+
+1. **Map the page**: [references/discovery.md](references/discovery.md). Produce
+   the inventory (endpoints, states, params, permissions, caps) before writing
+   code. No inventory, no story.
+2. **Skeleton first**: story + empty `defineStoryMocks`, then run it. The console
+   names the endpoints step 1 missed.
+3. **Inventory to controls**: [references/controls.md](references/controls.md).
+4. **Mock data and handlers**: builders in `__story_mockdata__`, handlers in the page's
+   mocks module.
+5. **Verify in the browser**: [references/verify.md](references/verify.md). Never
+   report the story as done without it.
+
+## Rules
+
+- **Default is the loaded page.** `export const Default: Story = {}` with no args,
+  every widget carrying data. Empty, loading and failed are variants or control
+  values, never the default.
+- **A control is a knob on a response**, resolved through `handlers`, `config` or
+  `effect`. Never a component prop, never a module mock added for one story.
+- **Every branch in the inventory is reachable from the panel.** A state that
+  needs a code edit to see is a missing control.
+- **Never re-declare what every story already has**: banner, side nav, data state
+  (loaded/loading/error), access preset, permissions, check state.
+- **A variant earns a story only when it is worth linking to**: an empty
+  workspace, a viewer, a page mid-load. Everything else stays a control.
+- **Endpoints the page owns go through `response.json`**, so the Data control
+  covers loaded, loading and failed in one declaration. Endpoints the page cannot
+  render without (ingestion detection, preferences, feature payloads) take a
+  plain resolver so the shell survives the loading and error states.
+- **Query-param state starts from `route`** (`/logs?tab=explorer`). In-page param
+  navigation works inside a story; a different pathname is blocked and reported
+  by the overlay. A control for a param is worth it only when the param is a page
+  mode someone would want to flip.
+- **File layout**: every story file for a page lives under
+  `src/pages/<Page>/stories/`: `<Page>.stories.tsx`, `<Page>.stories.mocks.tsx`,
+  payload builders in `stories/__story_mockdata__/<page>.ts`. Nothing
+  page-specific in `src/storybook/controls/`.
+- **The mocks are AI-owned and say so.** `<Page>.stories.mocks.tsx` and every file
+  under a `__story_mockdata__/` open with this banner, above the imports:
+
+  ```ts
+  /**
+   * AI-owned. Generated and maintained by the `signoz-page-story` skill.
+   * Do not hand-edit: regenerate instead.
+   */
+  ```
+
+  The root `.gitattributes` marks both paths `linguist-generated=true`, so the
+  reviewer gets them collapsed and spends the attention on the rendered page. The
+  story file is the human surface and never carries the banner. A file with the
+  banner has to stay regenerable from the page alone: no page knowledge in
+  `src/storybook/`, and builders typed from `src/api/generated` where the endpoint
+  has types, so a contract change is a compile error instead of a mock that lies.
+- **Reuse fixtures** from `src/mocks-server/` and `src/tests/fixtures/` where they
+  exist. An endpoint jest needs too belongs in `src/mocks-server/handlers.ts`.
+- **Shared response builders live in `src/storybook/msw/__story_mockdata__/`**: typed
+  helpers like `queryRangeV5ScalarResponse` that multiple pages need. Before
+  writing a response shape inline, check if a builder exists; if not and the
+  shape will repeat, add it there. Page-specific builders stay in the page's
+  `__story_mockdata__/`.
+- **No comment is the default.** Write one only for what the code cannot show:
+  a shape the backend dictates, an app bug the mock reproduces, an ordering or
+  cap the page depends on, a workaround and the reason for it. Never restate a
+  name, a type, or what a builder plainly builds; if the sentence reads as the
+  signature in prose, delete it. Nothing addressed to a reviewer. The one
+  comment a story always gets is its own doc comment: what it shows, in the
+  page's own terms.
+
+## Done means
+
+- [ ] `Default` shows the page with data, checked in dark and light
+- [ ] the mocks module and every `__story_mockdata__` file carry the AI-owned banner
+- [ ] every control flipped once, its effect seen on screen
+- [ ] console clean: no `[storybook] no msw handler`, no 501, no msw unhandled
+      request, no React warning
+- [ ] no navigation overlay on mount
+- [ ] `pnpm tsgo --noEmit`, `pnpm exec oxlint <files>`,
+      `pnpm exec oxfmt --check <files>` all clean. The repo has no
+      prettier: `pnpm exec prettier` prints a pass while exiting 254

+# Turning the inventory into controls
+
+Every row of the inventory becomes a control, a global control that already
+exists, or a documented reason it cannot be one.
+
+## Imports
+
+Paths written as `src/storybook/...` in prose are repo paths, not import
+specifiers. Stories import through the `@/` alias (`@/*` → `./src/*`); modules
+inside `src/storybook/` import each other relatively.
+
+| Import | From |
+| --- | --- |
+| `toggleControl`, `countControl`, `choiceControl`, `multiChoiceControl` | `../controls/controls` |
+| `defineStoryMocks`, `storyMocks` | `../controls/defineStoryMocks` |
+| `PageStoryArgs` | `../controls/resolveStoryMocks` |
+| `MockRequest`, `MockResponse` | `../controls/types` |
+| the page's mocks, from the story | `./<Page>.stories.mocks` |
+| `queryRangeV5ScalarResponse`, `queryRangeV5RawResponse`, etc. | `@/storybook/msw/__story_mockdata__/queryRange` |
+
+## Which builder
+
+`src/storybook/controls/controls.ts`:
+
+| The state is | Builder |
+| --- | --- |
+| on or off (a signal ingesting, a feature present) | `toggleControl` |
+| how many rows a list has | `countControl` |
+| one of several modes (tab, visibility, plan, severity filter) | `choiceControl` |
+| a subset (steps skipped, columns shown, signals selected) | `multiChoiceControl` |
+
+Rules that come with them:
+
+- `countControl` `max` goes past what the page renders, so a story can show the
+  cap being hit. `0` is the empty state, which is why an empty list rarely needs
+  its own story. When the cap is in the *request* (`?limit=5`) rather than the
+  renderer, stop `max` at the limit: a longer response is a body the backend
+  cannot send.
+- `choiceControl` options come from a `const` array typed with
+  `(typeof X)[number]`, not from string literals scattered in the handlers.
+- Defaults describe the fully-populated page. The panel starts where `Default`
+  starts.
+- `group` is `'<Page> · <facet>'`, such as `'Services · lists'` or
+  `'Alerts · rules'`. Keep a page's knobs in two or three groups, not one per
+  control.
+- `description` only when the name does not carry the effect (what dismissing
+  does, what the cap is, which widget it feeds).
+
+## Which hook
+
+`defineStoryMocks` takes three, all optional:
+
+- `handlers(values, response)`: the page's endpoints. Everything the page owns
+  goes through `response.json`, so the global Data control turns the whole page
+  into loading or failed without a second declaration. An endpoint the page
+  cannot render at all without (ingestion detection, preferences, license
+  payloads) takes a plain `rest.get(...)` resolver instead, so the shell stays
+  visible while the rest hangs or fails.
+- `config(values)`: `SignozStoryConfig` for knobs no endpoint covers: `route`,
+  `appContext`, `reduxState`, `queryBuilder`, `theme`.
+- `effect(values)`: module-level state no provider exposes.
+
+One endpoint feeding several widgets stays one handler that reads the request.
+`response.json` hands the request to the builder and awaits it, so reading a
+query param, or a POST body, does not cost the Data control:
+
+```ts
+rest.get(
+	'http://localhost/api/v1/explorer/views',
+	response.json((req) =>
+		savedViews(values.savedViews, req.url.searchParams.get('sourcePage') ?? 'logs'),
+	),
+),
+```
+
+```ts
+rest.post(
+	'http://localhost/api/v5/query_range',
+	response.json(async (req) => {
+		const body = (await req.json()) as QueryRangeRequestV5;
+		const signal = body.compositeQuery?.queries?.[0]?.spec?.signal;
+
+		return countResponse(values[`${signal}Ingestion`] ? 4213 : 0);
+	}),
+),
+```
+
+Reach for a plain `rest.post(url, async (req, res, ctx) => …)` only when the
+endpoint has to keep answering while the Data control is on `loading` or
+`error`: detection calls the page cannot render without.
+
+## Mutations
+
+A control drives the response, so a write the page makes against state a control
+owns does not stick: the refetch answers with the control's value and the button
+appears to do nothing. Two honest options: leave it declarative and say so in
+the PR, or move the state into `effect` so the handler can read what the page
+wrote. Never fake the write by mutating a builder's module state without saying
+where the state lives.
+
+## Wiring it up
+
+```ts
+// src/pages/Services/stories/Services.stories.mocks.tsx
+/**
+ * AI-owned. Generated and maintained by the `signoz-page-story` skill.
+ * Do not hand-edit: regenerate instead.
+ */
+export const servicesMocks = defineStoryMocks({
+	controls: {
+		services: countControl('Services', { group: LISTS, value: 8, max: 12 }),
+		apdex: choiceControl<ApdexState>('Apdex', {
+			group: HEALTH,
+			options: APDEX_STATES,
+			value: 'mixed',
+		}),
+	},
+	handlers: (values, response) => [
+		rest.post(
+			'http://localhost/api/v2/services',
+			response.json(() => buildServices(values.services, values.apdex)),
+		),
+	],
+});
+```
+
+```tsx
+// src/pages/Services/stories/Services.stories.tsx
+type ServicesArgs = PageStoryArgs<typeof servicesMocks>;
+
+const meta = {
+	title: 'Pages/Services',
+	component: Services,
+	...storyMocks(servicesMocks, { route: ROUTES.APPLICATION, layout: 'app' }),
+} satisfies Meta<ServicesArgs>;
+```
+
+`PageStoryArgs` folds in the global controls, so a story's `args` can set
+`access`, `dataState` or `banner` next to the page's own knobs and stay typed.
+
+## Not a control
+
+- Anything the global controls already cover: banner, side nav, data state,
+  access preset, permissions, check state.
+- A knob whose effect nobody can see on the page. Delete it or find the widget it
+  was supposed to drive.
+- A raw payload as an object control. Controls carry intent (`5 dashboards`,
+  `viewer`), and the builder turns intent into the payload.
+- Anything that needs a module mock or a component prop to work. If the state
+  cannot be produced from a response, config or module state, say so in the PR
+  instead of faking it.
+
+## Control or story
+
+Default to a control. Write a story when the state is worth a link:
+
+- the fresh workspace, because that is what a new user sees
+- the restricted user, when permissions visibly change the page
+- a page-defining mode (a tab, a category) that has its own layout
+
+Combinations of controls do not need stories, which is what the panel is for.
+
+Each story gets one prose doc comment: what it shows, in the page's own terms.
+Everywhere else the comment rule in SKILL.md applies: write one only for what
+the code cannot show.

+# Mapping a page
+
+Two passes: read the code, then let the running story correct you. Write the
+inventory down: it is what the controls are derived from, and the only
+protection against a story that renders one state and calls it a page.
+
+## Pass 1: read the page
+
+Start at `src/pages/<Page>/` and follow it outward: the containers it mounts
+(`src/container/<Feature>/`), the hooks those use, the components with their own
+fetches. Stop at leaf components that take props only.
+
+Grep recipes, run against the page's directories:
+
+| Looking for | Grep |
+| --- | --- |
+| endpoints | `useQuery\|useMutation\|useInfiniteQuery`, then the `api/` module it calls |
+| endpoint URLs | the api module's `axios.get\|post` |
+| endpoint URLs behind a generated hook | the hook lives in `src/api/generated/services/<name>/index.ts` and the URL only appears in the fetcher body: `rg 'url: \`' src/api/generated/services/<name>/` |
+| url state | `useUrlQuery\|useUrlQueryData\|useUrlSearchState\|useQueryState\|QueryParams\.` |
+| navigation | `useSafeNavigate\|history.push\|<Link` |
+| permissions | `useAuthZ\|AuthZGuard\|AuthZButton\|hasEditPermission\|routePermission` |
+| flags and prefs | `useFeatureFlag\|FeatureKeys\.\|USER_PREFERENCES\.\|userPreferences` |
+| empty and error branches | `isLoading\|isError\|isFetching\|length === 0\|!data` |
+| render caps | `slice(0,\|PAGE_SIZE\|pageSize\|limit` |
+
+`src/constants/routes.ts` has the route, `src/constants/query.ts` the param names,
+`src/lib/authz/README.md` how a permission check resolves.
+
+## The inventory
+
+One table, in the story's PR or scratch notes:
+
+| Endpoint | Feeds | States it can be in |
+| --- | --- | --- |
+| `GET /api/v1/x` | the header count | populated, zero, error |
+
+Plus four short lists:
+
+- **Query params** the page reads, and what each one switches.
+- **Permission checks** the page makes, and what disappears when each is denied.
+- **Preferences and flags** that change layout (dismissed banners, onboarding
+  checklists, opt-in views).
+- **Caps**: how many rows each list renders before it truncates or paginates.
+
+A state that appears in this inventory and not in the controls panel is a bug in
+the story.
+
+## Pass 2: let it run
+
+Write the story and an empty `defineStoryMocks({ controls: {} })`, point it at the
+route with `layout: 'app'`, then open it (see verify.md). The console is the
+oracle:
+
+- `[storybook] no msw handler` or a 501 from the catch-all: an endpoint pass 1
+  missed. Add it to the inventory.
+- an msw unhandled-request warning: a request going to an origin the handlers do
+  not answer on. handlers are declared against `http://localhost`.
+- a spinner that never resolves with the Data control on `loaded`: a handler
+  whose URL does not match what the page calls.
+- the navigation overlay on mount: the page redirects, usually because `route`
+  is wrong or a guard is failing on a permission the controls have not granted.
+
+Repeat until the console is silent. Only then start declaring controls.

+# Verifying a page story
+
+A story is not done because it compiles. It is done when each control has been
+seen changing the page and the console is silent.
+
+## Run it
+
+```bash
+cd frontend && pnpm storybook --ci --quiet   # :6006, background it
+```
+
+A newly added `.stories.tsx` takes a few seconds to appear in `index.json` on an
+already-running server; an empty first poll is not a broken `stories` glob.
+
+Story ids come from the meta title: `Pages/Services` → `pages-services`, plus the
+story export in kebab-case. Render one story on its own:
+
+```
+http://localhost:6006/iframe.html?id=pages-services--default&viewMode=story
+```
+
+## Flip controls from the URL
+
+Args are settable in the iframe URL, so a whole sweep runs headless without
+touching the panel. Booleans go as `!true` / `!false`, numbers bare, arrays
+indexed, several separated by `;`, and the theme through `globals`:
+
+```
+&args=services:0;apdex:poor;access:viewer;dataState:loading
+&args=signals[0]:logs;signals[1]:traces
+&globals=theme:light
+```
+
+That is the cheap way to check a control does something: load with and without
+it, diff the page text.
+
+## Drive it
+
+Playwright lives in the repo's e2e workspace, so a scratch script can use it
+directly:
+
+```js
+import pw from '<repo>/tests/e2e/node_modules/playwright/index.js';
+const { chromium } = pw;
+
+const browser = await chromium.launch();
+const page = await browser.newPage();
+const problems = [];
+page.on('console', (m) => {
+	if (m.type() === 'error' || m.type() === 'warning') problems.push(m.text());
+});
+page.on('pageerror', (e) => problems.push(e.message));
+
+await page.goto(`${story}&args=services:0`, { waitUntil: 'networkidle' });
+await page.locator('body').waitFor();
+console.log((await page.locator('body').innerText()).slice(0, 1500), problems);
+await browser.close();
+```
+
+Screenshots are worth taking for `Default` in both themes
+(`&globals=theme:light`): text extraction does not catch an unstyled page.
+
+## Gates
+
+- **Console silent.** `[storybook] no msw handler`, a 501 from the catch-all, an
+  msw unhandled-request warning, a React key or state warning: assume the story
+  is wrong first. A warning that survives is sometimes the app's. Prove it by
+  turning off the control that renders the widget and watching the warning go
+  with it, and by finding the same component elsewhere doing it right. Then
+  report the app bug in the PR. Never invent a field the API does not return to
+  silence a warning.
+- **No navigation overlay on mount.** "Navigation blocked in Storybook" on load
+  means the page is trying to leave: wrong `route`, or a guard denying on a
+  permission the controls did not grant.
+- **Every control moves something.** Sweep them one at a time from the URL and
+  diff the page text. A control with no diff is either wired to nothing or aimed
+  at a widget that is not rendering. Some only show their effect after an
+  interaction, such as a tab that has to be clicked or a select that has to be
+  opened. Drive that interaction rather than calling the control unobservable.
+- **Both themes render styled.** An unstyled page means the story is not inside
+  the provider decorator, or `<body data-theme>` was lost.
+- **Roles agree.** `<body data-signoz-story-role>` and
+  `<body data-signoz-context-role>` disagreeing means the page reads a different
+  `AppContext` than the story config fills.
+- **The page's own navigation works.** Tabs, filters and pagination that write
+  query params should re-render the page in place; only leaving the page belongs
+  in the overlay.
+
+## Then the usual
+
+```bash
+pnpm tsgo --noEmit

+name: storybook-visual-diff
+description: Screenshot a set of SigNoz Storybook stories, then pixel-diff two runs to see what a CSS or component change did, with the changes tinted over the new shot. Use when asked to take story screenshots, capture a visual baseline, compare before/after of a style change, or find which pages a change affects.
+---
+
+# Storybook visual diff
+
+Two scripts under `frontend/scripts`:
+
+- `story-shots.mjs` — screenshots stories off a running Storybook dev server.
+- `story-shots-diff.mjs` — pixel-diffs two runs and paints what moved.
+
+Output goes to `frontend/.story-shots/` (gitignored), one directory per run.
+
+## 0. Settle what is being compared, first
+
+A diff is only worth taking when the two runs straddle something. Run twice over
+the same tree and the answer is zero, or the noise floor: true, and useless.
+So before starting a server, pin down four things. Whatever the prompt already
+says, take it and do not ask again; ask only for what is genuinely missing, in
+**one** `AskUserQuestion` call.
+
+| To settle | Ask | Options |
+| --- | --- | --- |
+| Job | "What should this run produce?" | shoot only · baseline for a change you are about to make · compare against a change already in the working tree · compare this branch against another (`main` by default, or one the user names) · compare two configurations of the same story (`--args`, clock, width) · noise floor (same tree twice) |
+| Scope | "Which stories?" | offer 2-3 concrete selections read off `index.json` (a page, a `--title` prefix, everything), never open-ended |
+| Themes | "Which themes?" | dark · dark + light |
+| Read-out | "How should the diff read?" | `green` (changed pixels over the after shot) · `green-parallel` (before \| after \| diff, side by side) · `red` · `red-parallel` · `none` (keep both runs, do not diff) |
+
+Skip a row when the prompt answers it, and skip the whole call when the prompt
+answers all of it ("shoot the pods tooltips in both themes" needs no question).
+Skip Read-out too whenever the job is *shoot only*, and take `none` for what it
+says: shoot both sides, report both paths, run no comparison. When the prompt
+says nothing at all, ask; a silent guess here burns ~6 min per sweep on the
+wrong stories.
+
+The job decides which loop below to run:
+
+| Job | Loop |
+| --- | --- |
+| **shoot only** | §1, §2, stop. Report the paths. No diff, no second run. |
+| **baseline first** | the full loop, stopping after step 2 to hand the change back. The user makes it, then continue at step 4. |
+| **change already in the tree** | the tree *is* the after state. `git stash` (or check out the base commit) to shoot the before, restore, shoot the after. Confirm the working tree is clean enough to stash before touching it, and restore it even if a capture fails. |
+| **branch vs branch** | shoot the current branch, then `git switch <base>` in place (stash first if the tree is dirty), restart the dev server, shoot again, switch back and unstash. Restart matters: HMR does not survive a whole-branch swap cleanly. Get the tree back to where it started even if a capture fails. |
+| **noise floor** | two runs, same tree, diff. The number is the harness's floor, not a finding. |
+| **config vs config** | same tree, two runs that differ only in flags: `--args`, `--clock`, `--width`, `--theme`, `--motion`. Filenames stay identical, so the pairs line up and the caption names what changed. |
+
+## The loop
+
+1. Capture the baseline **before touching anything**.
+2. Capture it a second time and diff the two. That is the noise floor: anything
+   it reports is what the harness cannot hold still, and no conclusion about the
+   change may rest on those stories. Cheap on a handful of stories, ~6 min per
+   32, so on a wide sweep run it over the two or three stories the change is
+   aimed at instead of all of them.
+3. Make the change.
+4. Capture again into a third directory.
+5. Diff, then read the tinted shot of the largest movers to judge the change.
+
+## 1. One dev server, on a free port
+
+`storybook dev` keys its Vite dep cache off the config dir, so two servers on the
+same `-c` serve mismatched prebundles and every story dies with `Invalid hook
+call`. Check what is already up first — port 6006 is often another repo's
+Storybook, and its `index.json` then indexes the wrong stories:
+
+```bash
+for port in 6006 6007; do
+  curl -s -m 2 "http://localhost:$port/index.json" | head -c 60 && echo "  <- $port"
+done
+```
+
+Start the SigNoz one on a free port, from the repo's own binary so no package
+manager shim is in the way:
+
+```bash
+cd frontend
+nohup ./node_modules/.bin/storybook dev -p 6007 --no-open --quiet \
+  > "${TMPDIR:-/tmp}/signoz-storybook.log" 2>&1 &
+```
+
+It is ready when `curl -s localhost:6007/index.json` returns JSON whose
+`entries` hold SigNoz story ids.
+
+## 2. Capture
+
+Playwright is not a frontend dependency. The script finds it in `tests/e2e`
+(`pnpm -C tests/e2e install`, `@playwright/test` is enough) or in a global
+install, and launches Playwright's own chromium, falling back to an installed
+Chrome. Two escape hatches when that is not what a machine has:
+
+```bash
+export PLAYWRIGHT_MODULE=/path/to/playwright   # a different install
+export CHROME_PATH=/path/to/chrome             # a specific browser binary
+```
+
+Then pick the stories. `--list` prints the selection without shooting anything:
+
+```bash
+# every tooltip story of every page
+node scripts/story-shots.mjs .story-shots/baseline \
+  --port 6007 --title Pages/ --name tooltip --theme dark
+
+# a handful of stories by id or by title/name substring, both themes
+node scripts/story-shots.mjs .story-shots/baseline \
+  --port 6007 --stories pages-noz,dashboards/detail --theme dark,light
+```
+
+| Flag | Meaning |
+| --- | --- |
+| `--stories <match>` | id or `Title/Name` substring, repeatable or comma-separated. Omit for every story. |
+| `--title <prefix>` | only titles starting with the prefix (`Pages/`, `Components/`) |
+| `--name <match>` | only story names containing the match |
+| `--theme dark,light` | one pass per theme; omit for the story's own default (dark) |
+| `--args <k:v;k2:v2>` | arg overrides, Storybook's own `?args=` syntax, repeatable. A dotted value is dropped by Storybook itself, so map it to a slug inside the story's mocks |
+| `--port` | dev server port, or `$SB_PORT` |
+| `--width <px>` | the only fixed dimension, default 1680 |
+| `--height <px>` | shortest the viewport may be, default 1200 |
+| `--max-height <px>` | tallest it may grow to, default 8000 |
+| `--grow <what>` | `scrollers` (default) grows the viewport until the page's own scrollers fit, `document` only follows the document height, `none` keeps `--height` |
+| `--settle <ms>` | wait after the page goes quiet, default 1500 |
+| `--clock <iso\|live>` | wall clock the page reads, passed to the preview as `?storyClock`; `live` unfreezes it |
+| `--motion` | keep animations and transitions running (sets the `motion` global to `live`) |
+| `--ignore <selector>` | hide matching elements, on top of `[data-shot-ignore]` and `[data-chromatic="ignore"]` |
+| `--flat` | write `<out>/<id>.png`, no theme directory |
+| `--no-caption` | leave the caption band off the shots |
+| `--list` | print the matched stories and exit |
+
+Files land at `<out>/<theme>/<story-id>.png`, next to a `shots.json` recording
+what each shot is (id, title, name, theme, `ok`/`busy`, the caption's height in
+rows) and how the run was configured (args, clock, width, height, grow, motion,
+settle, ignore). Keep the flags identical between the two runs or the diff pairs
+nothing.
+
+Every shot carries the caption band described below, so a single screenshot says
+what it is on its own. `--no-caption` leaves it off, and so does a machine
+without ImageMagick (with a warning). The band never changes the shot's width
+(long text wraps rather than widening the canvas) and its height is recorded, so
+the diff crops it back off and never reports one caption against another. Two
+runs whose captions are different heights still diff to zero. A story that never held still for two
+identical frames is logged `busy` instead of `ok` — treat its diff as suspect.
+
+Dark alone is enough while iterating on the harness; add `light` for the run you
+report.
+
+## 3. Diff
+
+```bash
+node scripts/story-shots-diff.mjs .story-shots/baseline .story-shots/capped .story-shots/diff
+```
+
+Prints `<changed pixels>  <theme>/<story>.png`, largest first, and writes one
+image per pair. Needs ImageMagick for PNG encode/decode (7's `magick`, or 6's
+`convert`/`identify`/`montage`); the comparison itself is in the script.
+
+| Flag | Meaning |
+| --- | --- |
+| `--mode green` | default. The after shot with the changed pixels painted over it, exactly the pixels that changed. What Chromatic shows. |
+| `--mode green-parallel` | `previous \| current \| diff` in one image, each tile labelled above it, on a gutter inverted from the theme. The diff tile is the `green` one, so the after shot stays readable underneath. |
+| `--mode red` | the after shot faded to 10%, changed pixels in red. A pixelmatch-style diff, easiest to read when the change is a thin edge. |
+| `--mode red-parallel` | the same three tiles, with the `red` diff. Best when the change is a thin edge that the unfaded shot would swallow. |
+| `--threshold <0..1>` | how far a pixel must move to count. Default 0.063, Chromatic's `diffThreshold`. |
+| `--include-aa` | count antialiasing changes too. Off by default, as in Chromatic. |
+| `--tint <#rrggbb>` | override the mode's colour. |
+| `--no-caption` | drop the caption band. |
+
+### The caption
+
+Both scripts stamp a band on top of what they write: `story-shots.mjs` on each
+shot, from the story and the run's own settings; `story-shots-diff.mjs` on each
+diff, read out of the two runs' `shots.json`. It carries the story's
+`Title/Name`, then its id, theme and `busy` flag, then the settings both runs
+shared, each reading `key:value`. Whatever the two runs did **differently** goes
+on the side it belongs to: under `previous` and `current` on the parallel tiles,
+on two lines of the band otherwise. So a pair that differs only in `--args` says
+so on its face, which is what makes several shots of one story tellable apart.
+
+The shots' own bands are cropped off before comparing and before going into the
+tiles, so nothing in the output is a diff of a caption. Type size follows the
+image width, so it stays readable with the whole image viewed at fit-to-width;
+the heading is set in an installed sans and the detail lines in a mono, falling
+back to ImageMagick's default when neither is on the machine. Without a manifest
+the band falls back to the file path, and a directory of captioned shots whose
+`shots.json` is missing has nothing to crop by, so its captions do land in the
+diff. Keep `shots.json` next to the shots.
+
+### How the comparison works
+
+Chromatic's own capture and diff run server-side — `chromatic-cli` uploads a
+built Storybook and contains no capture or comparison code at all. What is public
+is the parameter contract, and the numbers in it say what the comparison is:
+`diffThreshold` defaults to `0.063` on a 0-1 scale, which is pixelmatch's
+`threshold`, and `diffIncludeAntiAliasing` defaults to false, which is
+pixelmatch's `includeAA: false`. So the script implements that comparison:
+
+1. Both PNGs are read as raw RGBA through `magick … RGBA:-`.
+2. Per pixel, the squared YIQ distance between the two colours (weights
+   `0.5053 / 0.299 / 0.1957`), compared against `35215 * threshold²` — 35215 is
+   the largest distance two 8-bit colours can have. Chroma is included, so a
+   colour swap at equal brightness still counts.
+3. A pixel over the threshold is dropped when it is only antialiasing: it is the
+   darkest or lightest of its eight neighbours, and the other image has a pixel
+   around there doing the same job. This is what keeps a subpixel glyph edge from
+   reading as a change.
+4. What survives is painted at full opacity, one output pixel per changed input
+   pixel. No dilation, no blobs — a one-pixel shift shows as a one-pixel line.
+
+A pair whose shots are different sizes is compared over the overlap, and every
+row and column that exists in only one of them counts as changed.
+
+Pairing is by `<theme>/<story-id>.png`, so a story that exists on only one side
+(new on the feature branch, renamed, retitled) has nothing to pair with and is
+skipped silently. On a branch-vs-branch run, compare the two runs' file lists
+before reading the numbers.
+
+## What makes a shot reproducible
+
+Most of it is in the preview, not in the script, so a Chromatic build in the
+cloud shoots the same page: `.storybook/preview-head.html` freezes the clock,
+and `settleForCapture` (the preview's `afterEach`, which runs after `play`)
+parks the animations and snaps the bottom-pinned lists. The script drives the
+rest:
+
+- **Storybook's own render phase is the readiness signal.** It waits for
+  `window.__STORYBOOK_PREVIEW__.storyRenders[].phase === 'finished'`, which is
+  reached only after the loaders, the decorators and the story's `play` are done.
+  A DOM check cannot see a `play` still running. (Storybook 10 spells the final
+  phase `finished`, not `completed`.)
+- **Network quiescence, not `networkidle`.** react-query retries and msw keep
+  requests going after load, and a few stories hang a request by design, so the
+  wait is "no request for 600ms", capped at 15s.
+- **The clock is frozen** (`2026-06-15T12:00:00Z`), by the preview itself. Chart windows, `4 mins ago`
+  labels and trial countdowns all derive from `now`; a live clock alone moved
+  8000 pixels on the dashboards list and redrew every chart axis.
+- **Animations are parked on their last frame** by `html.sb-still`, a
+  zero-length single iteration with `forwards` fill, plus `prefers-reduced-
+  motion`. The Motion toolbar item (`still` by default) turns it off. An infinite
+  spinner is otherwise caught at a random angle.
+- **`document.fonts.ready`**, because text reflows when a face lands late.
+- **Lists pinned to their bottom are snapped onto it**, once by the preview and
+  again by the script after the page goes quiet. A virtuoso list settles a
+  few pixels short of the end depending on the order its items were measured in.
+- **Two identical frames in a row**, because what a page is still waiting on is
+  often not observable from outside it.
+- **`[data-shot-ignore]`, `[data-chromatic="ignore"]` and `--ignore <selector>`**
+  hide a region that cannot be held still; Chromatic excludes the same attribute
+  from its comparison.
+- **The width is the only fixed dimension.** Chromatic's `viewports` are widths;
+  the height follows the page. `src/styles.scss` pins `html, body, #root` to
+  `height: 100%; overflow: hidden`, so the document never outgrows the viewport
+  and its height says nothing: what overflows are the shell's inner scrollers.
+  `--grow scrollers`, the default, grows the viewport until the tallest in-flow
+  scroller fits, so nothing is cut off and no scrollbar is left in the shot (the
+  dashboards list goes to 2226px in one round). Popups are skipped — they are out
+  of the flow, and a tall dropdown would otherwise drag the shot to a height
+  nothing on the page needs. A page that sizes a panel in `vh` grows its own
+  content as the viewport grows, so no height ever fits it and the rounds only
+  chase — `.alert-chart-container` is `57vh`, which puts Create Alert's fixed
+  point at 4344px with an empty band on top. Those pages are shot at `--height`
+  with their own scrollbar, which is what they look like in a browser, and the
+  log says `(viewport-sized content, stopped chasing Npx)`.
+
+With all of that, 29 of the 32 page tooltip stories are byte-identical across
+runs. The three that are not, and why:
+
+| Story | Residual | Cause |
+| --- | --- | --- |
+| `kubernetes-pods--tooltips-in-options-panel` | ~13k px | 24 tooltips held open in an overlapping cluster; they portal to `body` in mount order, and the drawer's own tooltips mount before or after the list's depending on when their data lands, so overlapping tooltips stack differently. Panel geometry itself is stable. |
+| `settings-role-editor--tooltips-in-json-editor` | ~2.5k px | monaco re-measures and lands one pixel off. |
+| `traces-trace-details--tooltips` | ~800 px | same class, one row of the waterfall. |
+
+Each is bimodal — two stable arrangements — so the same number reappears run
+after run. Diff a story against itself before believing its number, and reach
+for `--ignore` when a region cannot be settled.
+
+## Gotchas
+
+- **Zero pixels is a real answer.** A story whose tooltips are all short is
+  unaffected by a tooltip rule; it is not a broken capture.
+- **The selector matters more than the rule.** A global rule on
+  `[data-slot='…']` only reaches design-system components. antd's own tooltips
+  (`.ant-tooltip-inner`, e.g. the Create Alert help popups) are untouched, which
+  is why some stories show no diff at all.
+- **Global style overrides need `!important`.** `src/styles.scss` loads before
+  the design system injects its CSS-module styles at runtime, so a plain rule on
+  a `[data-slot='…']` element loses. A component-level `!important` of the same
+  specificity still wins over it — `PanelStatusPopover.module.scss` keeps its own
+  `max-width: 520px !important`.
+- **A fresh context per story** is why a full sweep takes ~6 min for 32 stories.
+  Reusing one page loses the msw service worker re-registration race and stories
+  start failing after a few navigations.
+- **Stories behind a hover, drawer or modal** only render what their `play`
+  reaches. If a state is missing from the shot, the story needs the `play`, not
+  the script.

+# ClickHouse SQL
+
+Telemetry queries are generated as ClickHouse SQL text, most of it through [go-sqlbuilder](https://github.com/huandu/go-sqlbuilder) and executed with [clickhouse-go](https://github.com/ClickHouse/clickhouse-go). Attribute names, label names, body keys, aliases and dashboard variable values are user or telemetry input, so every one of them has to be quoted before it becomes part of the text.
+
+## How do I quote a name or a value?
+
+Use [pkg/clickhousesql](/pkg/clickhousesql/clickhousesql.go). Never build a quoted token with `fmt.Sprintf`, string concatenation or `strings.ReplaceAll`.
+
+| You need | Use | Example |
+| --- | --- | --- |
+| a column, alias or JSON sub-column name | `clickhousesql.Identifier(name)` | `` body_v2.`user.name` `` |
+| a string in a map read, a function argument, an `IN` list | `clickhousesql.StringLiteral(value)` | `attributes_string['http.method']` |
+| a Go scalar or list rendered as a literal | `clickhousesql.Literal(value)` | `['a','b']` |
+| a needle for `LIKE` | `clickhousesql.LikePattern(value)` | `"%" + clickhousesql.LikePattern(name) + "%"` |
+
+```go
+expr := fmt.Sprintf("multiIf(mapContains(%s, %s), %s[%s], NULL)", column, clickhousesql.StringLiteral(key.Name), column, clickhousesql.StringLiteral(key.Name))
+alias := clickhousesql.Identifier(fmt.Sprintf("__GROUP_BY_KEY_%d_%s", i, key.Name))
+```
+
+Values compared against a column are bound as arguments (`sb.E(column, value)`), never rendered into the text.
+
+Filter expressions are a different language. A value placed into a filter expression string goes through `querybuilder.FilterStringLiteral`, which quotes for that grammar.
+
+## Where does `sqlbuilder.Escape` go?
+
+go-sqlbuilder compiles the text it is given: `$0`, `$1`, `${name}` and `$?` are read as argument references and `$$` as a single `$`. The compiled text is everything passed to `Select`, `SelectMore`, `GroupBy`, `OrderBy`, `Having`, `From`, a raw string passed to `Where`, `And` or `Or`, and a compiled subquery joined or selected from another builder, which is compiled a second time. The `Cond` helpers (`sb.E`, `sb.Like`, `sb.In`, `sb.IsNotNull`, ...) write their field argument verbatim.
+
+- A name or expression that ends up in compiled text is wrapped with `sqlbuilder.Escape` once, at the point where it enters that text. Materialized column names carry `$$`, so this is what keeps them intact.
+- A field passed to a `Cond` helper is not escaped.
+- Text that never passes through a builder is not escaped: CTE fragments joined with `querybuilder.CombineCTEs`, a `UNION` assembled with `fmt.Sprintf` from already compiled statements, raw queries sent straight to the store.
+- Bind placeholders produced by `sb.Var` or the `Cond` helpers must not be escaped, so escape the identifier-bearing part before combining it with them: `fmt.Sprintf("match(%s, %s)", sqlbuilder.Escape(fieldExpr), sb.Var(value))`.
+
+## How do I check SQL a user wrote?
+
+A statement typed into a ClickHouse query panel is validated with `clickhousesql.ErrIfStatementIsNotValid`. It parses the text with [clickhouse-sql-parser](https://github.com/AfterShip/clickhouse-sql-parser) and refuses anything but a single `SELECT`, a table function other than the row generators (`numbers`, `zeros`, `generate_series`), a function that reads a file, a dictionary or the server binary, the `system` and `information_schema` databases, and a `SETTINGS readonly` override. Each refusal carries one of the package's `Code*` values.
+
+## Why is `$` written as `\x24`?
+
+Inside an identifier or a literal, `clickhousesql` writes a `$` as `\x24` when a digit, `{` or `?` follows; ClickHouse decodes the escape, so the name is unchanged on the server. Two tools between the builder and ClickHouse read such a `$` as a placeholder: go-sqlbuilder resolves `$0` in a compiled fragment to its own WHERE clause and recurses, and clickhouse-go refuses a query that mixes a `$<digits>` numeric placeholder with `?` arguments. Any other `$` stays literal, so `resource_string_service$$name` renders exactly as written.
+
+## What should I remember?
+
+- Every identifier and literal built from a name or a value goes through `pkg/clickhousesql`.
+- `sqlbuilder.Escape` wraps compiled text once; `Cond` fields and text assembled outside the builder are left alone.
+- Filter expression literals use `querybuilder.FilterStringLiteral`.
+- A statement written by a user is validated with `clickhousesql.ErrIfStatementIsNotValid`.
+- When adding a builder or a module that emits SQL, run its queries with a name containing a backtick, a quote, a backslash and `$0`; the integration suites under `tests/integration/tests/queriercommon` do this for the query builder.

 ```
 
-### FieldMapper
+### Storage
 
-**Contract:** Given a `TelemetryFieldKey`, return a ClickHouse column expression that yields the value for that field when used in a SELECT.
+**Contract:** `qbtypes.Storage` in `pkg/types/querybuildertypes/querybuildertypesv5/qb.go`. One implementation per signal: traces, logs, metrics, audit, rule state history, the resource fingerprint sub-query, and the related-values metadata.
 
-**Principle:** This is the *only* place where field-to-column translation happens. No other layer should contain knowledge of how fields map to storage. If you need a column expression, go through the FieldMapper.
+A storage answers four questions and nothing else:
 
-**Why:** The user says `http.request.method`. ClickHouse might store it as `attributes_string['http.request.method']`, or as a materialized column `` `attribute_string_http$$request$$method` ``, or via a JSON access path in a body column. This variation is entirely contained within the FieldMapper. Everything above it is storage-agnostic.
+- `Read(key)`: one call for one field key. It returns the bare SQL read (no alias, no guard, no cast), the membership test (`Presence`, arg-free so it can sit inside guards) and its negation in the storage's own form (`Absence`), what a row without the key reads (`Absent`, below), whether the stage cast must leave the native type alone (`KeepType`: time columns, metrics labels), and whether the key filters but cannot be selected (`FilterOnly`: the legacy string body). It honors the materialization and the evolutions the key carries.
+- `Fallback(key, operator, value)`: the field keys that could hold a key metadata does not report: column aliases, the type variants of a map read, body paths, and virtual keys that compile to structural predicates (a span search scope, a full-text search over a scope).
+- `Traits()`: the storage's part in the resource fingerprint split, whether it supports body functions, what it does with an unknown key, and which contexts mean "this signal's own record".
+- `Compile`: the one override, for a storage with its own condition language (the body JSON language in logs, the index hints of the resource fingerprint, the polarity form of the related values, the String-typed labels of metrics). Every other storage returns `querybuilder.SharedCondition`.
 
-### ConditionBuilder
+**Principle:** A storage describes its field keys. It never decides a guard, an ambiguity, a warning, or the shape of a fold. Those decisions are derived one time, in the generic layer, from those descriptions.
 
-**Contract:** Given a field key, an operator, and a value, produce a valid SQL predicate for a WHERE clause.
+### Absent
 
-**Dependency:** Uses FieldMapper for the left-hand side of the condition.
+`Read` returns the field's `Absent`: what a row without the field reads. It is a property of the read, not of the column. `resource.x::String` reads the empty string for an absent row, the multi-era fold `multiIf(..., NULL)` reads NULL, and a table column always reads a real value. Every guard derives from it:
 
-**Principle:** The ConditionBuilder owns all the complexity of operator semantics, i.e type casting, array operators (`hasAny`/`hasAll` vs `=`), existence checks, and negative operator behavior. This complexity must not leak upward into the StatementBuilder.
+| WhenAbsent | Absent row reads | Positive filter | Raw select | Multi-candidate column | Field keys |
+|---|---|---|---|---|---|
+| `AlwaysPresent` | a real value | no guard | no guard | no branch, ends the candidate list | table columns |
+| `AbsentIsSentinel` | `''`, 0, false, and that is not a value | exists guard | exists guard | presence branch | map attributes, cast JSON paths, string families |
+| `AbsentIsNull` | NULL | no guard | no guard | presence branch | multi-era folds, body JSON paths, numeric families |
+| `AbsentIsValue` | `''`, and that is the keyless contract | no guard | no guard | no presence branch | metrics labels, rule state history labels |
 
-### AggExprRewriter
+### The generic layer
 
-**Contract:** Given a user-facing aggregation expression like `sum(duration_nano)`, resolve field references within it and produce valid ClickHouse SQL.
+`pkg/querybuilder` needs two inputs, made one time per request:
 
-**Dependency:** Uses FieldMapper to resolve field names within expressions.
+- The metadata keys: `keys := metadataStore.GetKeysMulti(...)`, the field keys the metadata store reports for the query's names, as `map[name][]*TelemetryFieldKey`.
+- `q := querybuilder.NewQueryInfo(ctx, orgID, fl, signal, metric, startNs, endNs)`: the time range every read needs, the signal and the queried metric that family admission needs, and the query-path flags (`FamiliesOn`, `BodyJSONOn`), evaluated one time.
 
-**Principle:** Aggregation expressions are user-authored strings that contain field references. The rewriter parses them, identifies field references, resolves each through the FieldMapper, and reassembles the expression.
+The functions, from the outside in:
 
-### StatementBuilder
+| Function | Does |
+|---|---|
+| `PrepareWhereClause(query, opts)` | The filter visitor. Parses the filter grammar and compiles each term through `RejectsBodyFunction`, `Resolve`, and `Condition`. Returns the WHERE clause, the warnings, and the cost-guard flag. |
+| `NewAggExprRewriter(settings, fullTextColumn, storage, fl, signal)` | Parses an aggregation expression such as `sum(duration_nano)` and resolves each field reference through `ResolveColumn`. |
+| `ResolveColumn(ctx, q, storage, key, target, metadata)` | `Resolve` with `FilterOperatorUnknown`, then `Column`. The column stages (raw select, order by, group by, aggregation arguments) call it. |
+| `Resolve(ctx, q, storage, key, operator, value, metadata)` | One requested key to its meanings in this storage (see "A resolved key"). |
+| `Condition(ctx, q, storage, resolved, dropResourceFields, operator, value, sb)` | A resolved key to the conditions of one filter term: the split narrows the fields, and each field compiles through `storage.Compile`. |
+| `Conditions(...)` | `RejectsBodyFunction`, `Resolve`, and `Condition` in one call, for callers outside the visitor: the related-values metadata, the scoped traces predicate resolver, tests. |
+| `Column(ctx, q, storage, resolved, target)` | A resolved key to one bare column expression. The caller aliases. |
+| `RejectsBodyFunction(traits, operator)` | Before resolution: a storage without body functions (`has`, `hasAny`, `hasAll`, `hasToken`, `search`) errors; the fingerprint side of a split skips the term, because the main query evaluates it. After resolution, `Condition` errors when `has`, `hasAny`, `hasAll`, or `hasToken` lands on a map-backed key (resource, attribute, scope), before the split could drop it. |
+| `SharedCondition(...)` | The `Compile` of every storage without its own condition language: `LogicalRead`, the shared data-type collision cast, `OperatorCondition`, then the guard rule. |
+| `OperatorCondition(...)` | The operator switch over an already cast read. A storage with its own cast policy composes with it. |
+| `LogicalRead(...)` | The only place family expressions are built. A single-member field reads through its member. A family merges the member reads current-first (`COALESCE(NULLIF(m1, ''), NULLIF(m2, ''), '')` for strings, `multiIf` with a NULL tail for numbers), ORs the member presence tests, and reads for a row without any member what the merge's tail reads. A member with a value map reads through `TransformRead`. `NOT EXISTS` is the read's `Absence`, the storage's own negated form. |
 
-**Contract:** Given a complete `QueryBuilderQuery`, a time range, and a request type, produces an executable SQL statement.
+### A resolved key
 
-**Dependency:** Uses all three abstractions above.
+`Resolve` turns one requested key into a `Resolved` value. It is the only thing the condition builder and the column expression builder receive. Compile it with the operator and value it was resolved with: the stage is the operand, and a nil value means a column or presence use.
 
-**Principle:** This is the composition layer. It does not contain field mapping logic, condition building logic, or expression rewriting logic. It orchestrates the other abstractions. If you find storage-specific logic creeping into the StatementBuilder, push it down into the appropriate abstraction.
+```go
+type Resolved struct {
+	Key          *TelemetryFieldKey // the spelling the request used
+	Fields       []*LogicalField    // its meanings in this storage, one per interpretation
+	FromFallback bool               // the fields came from the storage's Fallback, not from metadata matches
+	Ambiguous    bool               // the matches held several interpretations
+	Skipped      bool               // the storage contributes nothing for this key
+	Warnings     []string           // the warnings to surface: ambiguity, not-found
+}
+```
+
+A `LogicalField` is one meaning: one name, context, and data type, backed by one or more physical members. A family (one field with several spellings) is one logical field with several members, current spelling first. Ambiguity (one name, different fields) is several logical fields.
+
+The resolution order is the same for every storage and every stage:
+
+1. **Own context.** A key under one of the storage's own contexts (`span.x`, `log.x`) matches its own context first. Only when nothing matches does it look up as if it had no context, so `span.http.method` corrects to the attribute. Strict contexts (`resource.`, `attribute.`, `scope.`, `body.`) are honored 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.
+3. **Ambiguity.** A filter settles several interpretations by resource over attribute, with a warning. A column stage keeps every interpretation in metadata order and folds them, so a select or a group by sees the value wherever it is.
+4. **Intrinsic column first**, bare keys only. A column every row has leads the list, whether metadata reports it or the storage's `Fallback` does. A `Fallback` column key carries the data type its column reads as (`querybuilder.ColumnDataType`), and a same-named metadata key of a contradicting type drops; a time column has no field data type and merges none. 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.
+
+The condition builder then applies the fingerprint split (`MainOfSplit` drops the resource fields the sub-query serves and keeps fallback keys; `FingerprintOfSplit` keeps resource fields only), compiles each field, and the visitor joins the per-field conditions by the operator's polarity. The column expression builder reads each field through `LogicalRead`, casts for the coerced stages unless the read keeps its type, guards by `Absent`, and renders one candidate bare or several as `multiIf(..., NULL)`. A filter-only candidate drops; the error surfaces only when none remains.
 
 ### Invariant: No layer skipping
 
-The StatementBuilder must not call FieldMapper directly to build conditions, it goes through the ConditionBuilder. The AggExprRewriter must not hardcode column names, it goes through the FieldMapper. Skipping layers creates hidden coupling and makes the system fragile to storage changes.
+A statement builder must not spell a column or a condition. It calls `ResolveColumn` and the filter visitor. A storage must not decide a guard or an ambiguity. It declares `Absent` and answers the four questions. Skipping layers recreates the per-signal copies the contract removed.
