 ## Quick Reference
 
-Analytics events in Metabase use Snowplow with typed event schemas. Simple events are declared **where they are used** — `trackSimpleEvent` is generic and validates the payload at the call site.
+Analytics events in Metabase use Snowplow with typed event schemas. All events must be defined in TypeScript types before use.
 
 **Key Files:**
-- `frontend/src/metabase/analytics/event.ts` - Core tracking functions, `trackSimpleEvent` / `trackSchemaEvent` (import from `metabase/analytics`)
-- `frontend/src/metabase-types/analytics/event.ts` - The shared `SimpleEventSchema` only. **Do not add event types here** (see below)

+- Feature-specific `analytics.ts` files - Tracking function wrappers
 
 ## Quick Checklist
 
 When adding a new analytics event:
 
-- [ ] Pick an event name (snake_case, past tense)
-- [ ] Add a tracking function to the feature's `analytics.ts` file, calling `trackSimpleEvent()`
-- [ ] Keep any field unions (e.g. `"success" | "failure"`) as local types in that same file
-- [ ] Import and call the tracking function at the interaction point
-- [ ] Do **not** add an event type to `metabase-types/analytics/event.ts` or to any union
+- [ ] Define event type in `frontend/src/metabase-types/analytics/event.ts`
+- [ ] Add event to appropriate union type (e.g., `DataStudioEvent`, `SimpleEvent`)
+- [ ] Create tracking function in feature's `analytics.ts` file
+- [ ] Import and call tracking function at the interaction point
+- [ ] Use `trackSimpleEvent()` for basic events (most common)

-name: fe-modularization
-description: Deciding where frontend code lives — tier model, move mechanics, extension points, side effects, naming, and the traps. Use when moving code between modules, carving new modules, fixing boundary violations, adding a barrel or an endpoint, or reviewing module-shape decisions.
----
-
-# Frontend modularization
-
-The module is the unit of blast radius: dependency direction, test selection,
-bundle cones, and review scope all follow module boundaries. Every decision
-here serves one goal: **make the file locations tell the truth about who owns
-what and who may depend on whom.**
-
-## Hard rules (check these before anything else)
-
-- NEVER add an `export … from` re-export at an old path, and NEVER `export *`
-  from a barrel. Move the code, codemod every call site, delete the old path,
-  all in the same PR.
-- NEVER import past a module's `index.ts` when that module has
-  `enforcePublicApi: true`, and never past `metabase/ui`'s index at all. If
-  the barrel is heavy, the fix is making the module side-effect free (below),
-  not a deep import.
-- NEVER rewrite a consumer to a lower-level idiom to make the linter pass. If
-  the fix makes the consumer worse, the plan is wrong.
-- NEVER give a new module `enforceSharedTiers: false`; new modules ship
-  enforced with `enforcePublicApi: true` and an explicit `index.ts`.
-- NEVER move code without the consumer-tier check (procedure step 2).
-- ALWAYS delete a module's `enforceSharedTiers: false` line in the PR that
-  takes it to zero violations.
-- ALWAYS measure `bun run module-boundaries` before and after, and report the
-  numbers.
-- ALWAYS import `dayjs` from `metabase/dayjs`, routing from `metabase/router`,
-  Mantine from `metabase/ui`, react-redux hooks from `metabase/redux`; the
-  raw specifiers are lint-forbidden.
-
-## Files that are ground truth
-
-| what | where |
-|---|---|
-| module elements, tiers, `enforceSharedTiers`, `enforcePublicApi` | `frontend/lint/module-boundaries.mjs` |
-| shared sub-tiers and levels, cluster rules | `frontend/lint/shared-tiers.mjs` |
-| standalone boundaries lint (all violations, incl. grandfathered) | `bun run module-boundaries` (config `eslint.config.module-boundaries.mjs`) |
-| PR lint (only enforced modules fail CI) | `bun run lint-eslint-pure` |
-| side-effect-free directories and their exceptions | `frontend/build/shared/rspack/side-effect-free-modules.js` (`SIDE_EFFECT_FREE_PATHS`, `SIDE_EFFECT_PATHS`) |
-| the lint rules that enforce that promise | `metabase/no-module-side-effects`, `metabase/no-base-api-access` in `frontend/lint/eslint-plugin-metabase/rules/` |
-| public-api enforcement | `metabase/enforce-module-public-api` rule, driven by `getPublicApiModules()` |
-
-## The model
-
-Tiers: `lib < basic < shared < feature < app`. Imports point downward, never
-sideways at feature tier (features may not import features; app and EE may
-import anything). The shared tier is subdivided in `shared-tiers.mjs` into
-shared-utils (U0…), shared-platform (P0…), and shared-domain, each ordered
-into levels. A module imports only *strictly lower* levels of its sub-tier
-plus the sub-tiers below; same-level peers are deliberately forbidden, which
-is what makes cycles structurally impossible. A domain may hold two seats
-when consumers demand it: a low core and a high surface (metabase-lib below
-questions below query_builder; viz-core below visualizations).
-
-Enforcement is per module: `enforceSharedTiers: false` on an element exempts
-it from the level rules (counted by `bun run module-boundaries`, invisible to
-PR lint). Modules with `enforcePublicApi: true` may only be imported from
-outside via `metabase/<module>`, and import relatively inside.
-
-## Deciding where code lives (apply in order; first decisive test wins)
-
-1. **Who owns the concept?** Code lives with the module that owns its
-   concept, not the module that renders or calls it. A mode encoding dashboard
-   click behaviour is dashboard code even if viz executes it. Metabot
-   conversation state is metabot state even though the store registers it.
-2. **Consumer-tier check.** The destination must sit at or below the file's
-   *lowest* consumer. A single consumer below the proposed home vetoes the
-   move; report it, don't force it.
-3. **Only four legitimate fixes** for a bad edge: move the code to its
-   terminal home; invert through a designed extension point (a prop, an
-   injected component, a contract type owned by the socket); fix the tier
-   placement when the declared level is wrong; delete a thin wrapper (a rename
-   with no derivation isn't an abstraction — deleting it *is* the migration).
-4. **A bridge lives above the lower endpoint.** Code that needs both sides of
-   a boundary belongs in or above the higher module.
-5. **"Genuinely shared" is proven by consumers.** A shared address needs two
-   or more consumers the tier rules can't serve another way. One consumer
-   pretending to be shared is a feature module at the wrong address.
-
-## Extension points
-
-The socket's owner defines the contract; every plug lives with its extender.
-Visualization owns the `mode` prop and click interfaces, each surface supplies
-its mode; the editor owns its extension contract, metabot supplies tiptap
-extensions; querying owns `TemplateTagsSidebarProps`, parameters implements
-it.
-
-- Prefer plain props/injection at composition sites. `PLUGIN_*` registries are
-  for edition gating; single-reader slots move out to their reading module;
-  slots with many readers live in the module that owns the concept (every
-  slot the whitelabel plugin fills lives in `whitelabel`), tier permitting.
-  Keep contracts type-light so implementations can load lazily.
-- Identical injection at every callsite is acceptable until a fourth consumer
-  or second slot appears; then the composition deserves its own module above
-  both parts. Don't pre-build the wrapper.
-
-## Store shape
-
-A module that has redux state owns it:
-
-- `store/` is private: reducer, plain creators/action types, and selectors,
-  typed against the module's own state (`QueryBuilderStoreState`), never the
-  global `State`. Thunks live in `actions/` and import `store/`, never the
-  reverse.
-- The barrel is the state API: selectors for reads, creators/thunks for
-  writes.
-- Store roots (`reducers-main`, `reducers-public`, the SDK store) import each
-  slice from its module barrel and derive their own state type; no slice
-  registry, no `declare module` merging.
-- Cross-module writes: a callback prop when a composition point exists;
-  otherwise dispatch the owner's exported creator; an event only when the
-  emitter must not know its listeners. Raw `dispatch({ type: "…" })` strings
-  are banned. A reducer or listener matching another module's *internal*
-  action is the coupling to remove.
-- Slices that mirror one endpoint get deleted (the RTK cache is the state); a
-  fold over many sources with one writer (the metadata store) is kept as a
-  module-private slice behind the barrel.
-
-## Endpoints
-
-Endpoints migrate to their owning module via `Api.injectEndpoints` from the
-module's `api/` file (settings, metabot, transforms precedents); `metabase/api`
-trends toward the client only. There is one `Api` object per backend because
-tag invalidation only works within one instance. Consumers reach endpoints
-only through the owner's exports (`useGetCardQuery`, `cardApi.endpoints.…`),
-never by name through the base object; `metabase/no-base-api-access` allows
-injection only in `metabase/api` and `**/api/**` / `**/api.ts`, and reaching by
-name only in `metabase/api` and test support (`invalidateTags` /
-`resetApiState` are fine anywhere). Each endpoint move carries its
-metadata-store hookup: the owner calls `entitiesFetched` from its own
-`onQueryStarted`.
-
-## Import-time side effects
-
-Directories in `SIDE_EFFECT_FREE_PATHS` are marked `sideEffects: false` for
-rspack, so importing one export from their barrel no longer drags the whole
-barrel into a bundle. The price: nothing in those directories may do work at
-import time, or production silently drops it. `metabase/no-module-side-effects`
-enforces this over every listed directory (module-scope calls, writes to
-imported objects or globals, bare imports, control flow at import; escape
-hatches are `/* #__PURE__ */` and the rule's pure-callee list). Files that
-must run at import are listed in `SIDE_EFFECT_PATHS` (files or directories).
-
-- **A library the app configures gets a facade module** owning the vendor
-  import, the registrations, and the types, with the raw specifier
-  lint-forbidden outside it: `metabase/router`, `metabase/ui`,
-  `metabase/redux`, `metabase/dayjs`. Facades are the effect, so they never
-  enter `SIDE_EFFECT_FREE_PATHS`. Never re-register a vendor plugin locally
-  (`dayjs.extend`, `echarts` `use`).
-- **A patch a component needs is an explicit registration module,
-  bare-imported by the provider that needs it** and listed in
-  `SIDE_EFFECT_PATHS` (Mantine's `Popover.Dropdown` replacement, imported by
-  `ThemeProvider`).
-- **Effects with no value to import** (global CSS, polyfills, the CSP nonce,
-  EE plugin bootstrap) live in the entry's side-effects file and nowhere else.
-- **Registries are filled from the composition root at boot**
-  (`initializePlugins`, `registerVisualizations`), never by a module
-  registering itself at import.
-- **RTK injection stays at import**; when a module with an `api/` folder is
-  declared side-effect free, list `<module>/api/` in `SIDE_EFFECT_PATHS`.
-
-## Naming
-
-The feature keeps the plain product-surface name; a shared carve is named for
-what the shared part actually is: the concept when the concept is the shared
-thing (`settings`, `current-user`, `whitelabel`, `dayjs`), or a qualified
-capability when the plain noun is taken (`search-ui`, `metrics-ui`,
-`viz-core`, `data-studio-ui`). Never two modules distinguished only by tier
-prefix; never generic `-shared` / `-feature` suffixes.
-
-## Procedure for a move
-
-1. **Enumerate consumers honestly** (hook-name greps miss the last three):
-   ```
-   grep -rn "metabase/<module>" frontend/src enterprise/frontend/src frontend/test e2e
-   grep -rn "jest.mock(\"metabase/<module>" frontend enterprise/frontend
-   grep -rn "addMatcher(.*<endpoint>" frontend/src enterprise/frontend/src
-   ```
-   plus sibling files importing the moved file relatively. Classify each by
-   module and tier from `module-boundaries.mjs` / `shared-tiers.mjs`.
-2. **Consumer-tier check**: destination at or below the lowest consumer. If
-   not, stop and report the blocking consumer.
-3. **Measure before**: `bun run module-boundaries 2>&1 | tail -1` on the base
-   (write the number down).
-4. **Move**: `git mv`; codemod every importer to `metabase/<module>` (outside)
-   or a relative path (inside); add named exports to the destination barrel
-   for every symbol an outside consumer needs (each must have a real
-   consumer). Delete the old path. If the module didn't exist: add its element
-   in `module-boundaries.mjs` (ordered before any element it's carved from,
-   first match wins), its level in `shared-tiers.mjs`, `enforcePublicApi:
-   true`, an `index.ts`. If the move empties a module's violations, delete
-   its `enforceSharedTiers: false` line. If the module has an `api/` folder
-   and is side-effect free, list `<module>/api/` in `SIDE_EFFECT_PATHS`.
-5. **Verify** (all of these, report the numbers):
-   ```
-   grep -rn "<old path>" frontend enterprise/frontend e2e        # must be empty
-   bunx eslint --no-warn-ignored <touched files>
-   bun run lint-eslint-pure                                       # enforce-module-public-api included
-   bun run type-check-pure
-   bun run test-unit-keep-cljs <touched folders' specs>
-   bun run module-boundaries 2>&1 | tail -1                       # after; no violation may name the new files
-   bun run build-release:static-viz                               # only if viz/static-viz/ui/dayjs touched; hard 3.5 MiB budget
-   ```
-6. **Report**: count before/after (state count-neutral explicitly), the edges
-   removed by file, flags/rules deleted, barrel exports added, anything you
-   skipped and why, and any consumer you found that vetoed part of the move.
-
-## Traps (each has bitten at least once)
-
-- **Late binding.** A bare function reference in a `createSelector` input
-  array, a component identity captured for comparison, a `PLUGIN_*` object
-  read at module scope: all capture at import time and dodge jest spies, EE
-  overrides, and lazy loading. Read at call time (`(_state) => fn()`), or
-  inject.
-- **Plans go stale.** Verify every recipe against current code before
-  executing; things get merged, renamed, or turn out never to have existed.
-  Skip-and-report beats force.
-- **The linter's blind spots**: `export … from` re-exports, bare-specifier
-  packages (custom-viz), pre-seeded caches that never register tags. A grep
-  for the old path is the stronger claim than a green lint run.
-- **Path-keyed baselines reset on rename**: a generated per-file ledger
-  silently loses a file's history when it moves.
-- **A heavy barrel is a bundle hazard until its module is side-effect free.**
-  One constant imported from the `metabase/ui` barrel pulled Mantine into the
-  static-viz bundle and broke its budget; the fix was `SIDE_EFFECT_FREE_PATHS`,
-  never a deep import.
-- **Type augmentation is program-wide.** `declare module "dayjs"` (and
-  similar) makes plugin types available to any file in the same tsconfig, so
-  a passing type-check never proves the setup ran; only importing the facade
-  does.
-- **Environment before diagnosis**: after a dependency-touching merge,
-  `bun install` before declaring a failure real; worktrees share staleness
-  through the node_modules symlink, and a stale `target/cljs_dev` makes
-  `type-check-pure` fail on `metabase-lib/metric/core.ts` (rebuild cljs in the
-  worktree).
-

 The same discipline applies to **dimensional** values — radius, spacing/padding/gap, elevation/shadow, and typography (font size, line-height, weight). Prefer the codebase's existing scale variable over a literal: `--mantine-radius-*`, `--mantine-spacing-*`, `--mantine-shadow-*`, and the Mantine font tokens.
 
-But Figma's scales don't always line up with the codebase's.

Only fall back to a literal if the user confirms it's an accepted one-off, and leave a short comment in the code explaining why. The codebase scales are defined in `frontend/src/metabase/ui/theme.ts` (`SPACING_SCALE`, `RADIUS_SCALE`, `LIGHT_SHADOWS`/`DARK_SHADOWS`).

-;; Budgets for kondo suppressions: inline `:clj-kondo/ignore` forms per linter (:ignore-counts), and
-;; config-level waivers in .clj-kondo/config.edn (:config-counts -- :off switches and :exclude entries).
-;; Each :ignore-counts value is a non-negative integer budget, or :unlimited for no ceiling.
-;; Checks fail when a count exceeds its numeric budget; unused budget is allowed.
-;; Any ignore outside :comment-exempt needs an explanatory comment directly above or trailing on its line.
-;; `./bin/mage kondo-ratchets-shrink` lowers budgets unless `--seed` explicitly adds or raises one.
-;; The workflow runs it on master, so feature branches do not need to record reductions.
-;; Raising or adding a budget (`--seed` for inline ignores, a manual edit for config) or widening the
-;; exemptions must be explained in the PR.
-;; :all is the vector-less ignore form, which suppresses every linter on the next form.
