 ## Testing
 
-Use `./bin/test-agent` to run backend tests. See the top-level CLAUDE.md for usage.
+- **Run a test:** `./bin/mage run-tests namespace/test-name`
+- **Run all tests in a namespace:** `./bin/mage run-tests namespace`
+- **Run all tests for a module:** `./bin/mage run-tests test/metabase/notification` Because the module lives in that directory.
+
+Note: the `./bin/mage run-tests` command accepts multiple args, so you can pass
+`./bin/mage run-tests namespace/test-name namespace/other-test namespace/third-test`
+to run 3 tests, or
+`./bin/mage run-tests test/metabase/module1 test/metabase/module2` to run 2 modules.

-description: Add OpenTelemetry tracing spans to Clojure code following Metabase tracing conventions. Use when instrumenting backend code with trace coverage.
----
-
-# Add Tracing Spans to Clojure Code
-
-This skill helps you add OpenTelemetry (OTel) tracing spans to the Metabase backend codebase using the custom `tracing/with-span` macro.
-
-## Reference Files
-
-- `src/metabase/tracing/core.clj` - `with-span` macro, group registry, SDK lifecycle, `best-effort-sanitize-sql`, Pyroscope integration
-- `src/metabase/task/impl.clj` - `defjob` macro that wraps Quartz jobs with root spans
-- `.clj-kondo/config/modules/config.edn` - Module boundary configuration
-
-## Module Architecture
-
-The tracing module has a deliberately minimal API surface. **Only 2 namespaces are public** (listed in `:api` in the module config):
-
-| Namespace | Role | Status |
-|---|---|---|
-| `tracing.core` | Primary API: `with-span`, groups, SDK lifecycle, Pyroscope, MDC, `best-effort-sanitize-sql` | **Public API** |
-| `tracing.init` | Side-effect loader for `quartz` and `settings` | **Public API** (init convention) |
-| `tracing.attributes` | `best-effort-sanitize-sql` implementation (re-exported via `tracing.core`) | Internal |
-| `tracing.settings` | Setting definitions (`MB_TRACING_*` env vars) | Internal |
-| `tracing.quartz` | Quartz JDBC proxy + JobListener | Internal |
-
-**Rules:**
-- Only require `[metabase.tracing.core :as tracing]` from outside the module. `tracing/best-effort-sanitize-sql` and all other public functions are available from this single namespace.
-- Do not add new API namespaces. Add new public functions to `tracing.core` instead.
-- Do not require internal namespaces (`tracing.attributes`, `tracing.settings`, `tracing.quartz`) from outside the module.
-- `:uses :any` on the `core` module does NOT bypass the target module's `:api` check — internal namespaces are still enforced.
-
-### Cyclic Dependency Avoidance
-
-`tracing/core.clj` is required by many modules across the codebase. It **must NOT** compile-time require `tracing.settings`, as this creates transitive cyclic load dependencies (e.g., `settings/core -> tracing/settings -> tracing/core -> events/impl -> events/core`).
-
-Instead, `tracing/core.clj` uses `requiring-resolve` for settings access:
-
-```clojure
-;; CORRECT — lazy runtime resolution, no compile-time dependency
-((requiring-resolve 'metabase.tracing.settings/tracing-enabled))
-
-;; WRONG — creates cyclic load dependency
-(require '[metabase.tracing.settings :as settings])
-(settings/tracing-enabled)
-```
-
-External library namespaces (clj-otel API, SDK, exporters) are safe to require normally — they don't participate in Metabase namespace cycles.
-
-**Important:** `requiring-resolve` must use **literal quoted symbols**. Kondo hooks validate that `required-namespaces` are all simple symbols, so dynamic construction fails:
-
-```clojure
-;; CORRECT — literal quoted symbol
-(requiring-resolve 'metabase.tracing.settings/tracing-endpoint)
-
-;; WRONG — kondo hook rejects this: "Assert failed: (every? simple-symbol? required-namespaces)"
-(requiring-resolve (symbol "metabase.tracing.settings" "tracing-endpoint"))
-```
-
-## Quick Checklist
-
-When adding tracing spans:
-
-- [ ] Module has `tracing` in its `:uses` set in `.clj-kondo/config/modules/config.edn`
-- [ ] Added `[metabase.tracing.core :as tracing]` to ns requires (alphabetically sorted)
-- [ ] Span wraps a meaningful I/O boundary (not pure computation)
-- [ ] Group matches the domain (check `src/metabase/tracing/core.clj` for registered groups; add a new one if none fit)
-- [ ] Span name follows dot-notation convention (`"domain.subsystem.operation"`)
-- [ ] Attributes use namespaced keywords (`:search/query-length`, `:db/id`)
-- [ ] No sensitive data in attributes (use `best-effort-sanitize-sql` for HoneySQL, never raw SQL)
-- [ ] No new tracing namespaces created (add to `tracing.core` instead)
-- [ ] No `DO_NOT_ADD_NEW_FILES_HERE.txt` violations in the target directory
-- [ ] Run `clj-kondo --lint <files>` to verify 0 errors, 0 warnings
-- [ ] Add or update tests in the corresponding `test/` path (see Testing section below)
-- [ ] Run tests: `clojure -X:dev:test :only <test-ns>`
-
-## The `with-span` Macro
-
-```clojure
-(tracing/with-span group span-name attrs & body)
-```
-
-- **group** - A keyword selecting which trace group this span belongs to (e.g., `:tasks`, `:sync`)
-- **span-name** - A string identifying the span in traces (e.g., `"search.execute"`)
-- **attrs** - A map of span attributes (e.g., `{:db/id 42}`)
-- **body** - The code to execute inside the span
-
-**When disabled:** zero overhead -- single atom deref + boolean check, body runs directly.
-**When enabled:** creates OTel span AND injects `trace_id`/`span_id` into Log4j2 MDC for log-to-trace correlation.
-
-## Trace Groups
-
-Groups are registered in `src/metabase/tracing/core.clj`. Check that file for the current list. The general rule: **match the group to the domain, not the call site.** If code runs inside a Quartz job but is logically search work, use `:search`, not `:tasks`.
-
-To add a new group:
-
-```clojure
-;; In src/metabase/tracing/core.clj
-(register-group! :my-domain "Description of what this covers")
-```
-
-Users enable groups via `MB_TRACING_GROUPS=tasks,search,sync` (comma-separated, or `"all"`).
-
-## Naming Conventions
-
-### Span Names
-
-Use dot-separated hierarchical names: `"domain.subsystem.operation"`. The domain prefix should match the group name:
-
-```
-search.execute              -- `:search` group
-sync.fingerprint.table      -- `:sync` group
-task.session-cleanup.delete -- `:tasks` group
-db-app.collection-items     -- `:db-app` group
-```
-
-### Attributes
-
-Use namespaced keywords. The namespace groups related attributes:
-
-```clojure
-:db/id              -- Database ID (integer)
-:db/engine          -- Database engine name (string)
-:db/statement       -- Sanitized SQL (string, via best-effort-sanitize-sql)
-:search/engine      -- Search engine name (string)
-:search/query-length -- Query string length (integer)
-:sync/table         -- Table name (string)
-:sync/step          -- Sync step name (string)
-:task/name          -- Task name (string)
-:http/method        -- HTTP method (string)
-:http/url           -- Request URL (string)
-```
-
-Invent new namespaced attributes as needed (e.g., `:pulse/id`, `:transform/count`). Keep values as primitives (strings, numbers, booleans) -- no maps or collections.
-
-## Step-by-Step: Adding a Span
-
-### 1. Check module boundaries
-
-Look up the module for your namespace in `.clj-kondo/config/modules/config.edn`. If `tracing` is not in the module's `:uses` set, add it (keep alphabetically sorted):
-
-```edn
-my-module
-{:team "MyTeam"
- :uses #{analytics config tracing util}}
-```
-
-### 2. Add the require
-
-```clojure
-(ns metabase.my-module.thing
-  (:require
-   [metabase.tracing.core :as tracing]
-   [metabase.util :as u]))
-```
-
-`best-effort-sanitize-sql` is available from `tracing.core` — no additional require needed.
-
-### 3. Identify the I/O boundary
-
-Only wrap code at **meaningful I/O boundaries**:
-
-**DO trace:**
-- External API calls (embedding APIs, metabot, webhooks)
-- Database queries (both app DB and user DB)
-- Network requests (HTTP calls to external services)
-- Heavy batch processing (batch indexing, batch embedding)
-- Top-level orchestration functions that coordinate multiple sub-operations
-
-**DO NOT trace:**
-- Pure computation (sorting, filtering, mapping)
-- Simple single-row lookups (`t2/select-one :model/Setting :key k`)
-- Every function in a call chain (only boundaries matter)
-- Trivial operations (string formatting, hash calculations)
-
-### 4. Wrap with `with-span`
-
-```clojure
-;; Simple span (no attributes needed)
-(tracing/with-span :search "search.init-index" {}
-  (do-expensive-thing))
-
-;; Span with static attributes
-(tracing/with-span :sync "sync.fingerprint.table"
-                   {:db/id (:db_id table)
-                    :sync/table (:name table)}
-  (fingerprint-fields! table fields))
-
-;; Span with computed attributes
-(tracing/with-span :search "search.execute"
-                   {:search/engine       (name (:search-engine ctx))
-                    :search/query-length (count (:search-string ctx))}
-  (search.engine/results ctx))
-
-;; Span with sanitized SQL (for dynamic HoneySQL queries)
-(let [hsql {:delete-from [(t2/table-name :model/Session)]
-            :where [:< :created_at oldest-allowed]}]
-  (tracing/with-span :tasks "task.session-cleanup.delete"
-                     {:db/statement (tracing/best-effort-sanitize-sql hsql)}
-    (t2/query-one hsql)))
-
-;; Sub-spans breaking a function into I/O phases
-(let [embedding (tracing/with-span :search "search.semantic.embedding"
-                                   {:search.semantic/provider (:provider model)}
-                  (get-embedding model search-string))
-      results   (tracing/with-span :search "search.semantic.db-query" {}
-                  (into [] xform reducible))]
-  (process results))
-
-;; Per-item iteration spans
-(doseq [e (search.engine/active-engines)]
-  (tracing/with-span :search "search.ingestion.update" {:search/engine (name e)}
-    (search.engine/update! e batch)))
-```
-
-### 5. Add tests
-
-Create or update tests in the corresponding `test/` path. Follow the patterns in existing tracing tests:
-
-- **Reference tests:** `test/metabase/tracing/quartz_test.clj`, `test/metabase/server/middleware/trace_test.clj`
-- Use `tracing/init-enabled-groups!` / `tracing/shutdown-groups!` with `try`/`finally` to manage group lifecycle
-- Test both enabled and disabled paths (verify zero overhead when group is off)
-- Use `reify` mocks for Java interfaces (Connection, PreparedStatement, JobListener, etc.)
-- Add `(set! *warn-on-reflection* true)` and type-hint proxy/reify calls to avoid reflection warnings
-
-```clojure
-(deftest my-span-enabled-test
-  (testing "when group is enabled, span is created"
-    (try
-      (tracing/init-enabled-groups! "my-group" "INFO")
-      ;; ... test that span behavior occurs ...
-      (finally
-        (tracing/shutdown-groups!)))))
-
-(deftest my-span-disabled-test
-  (testing "when group is disabled, code runs without tracing"
-    (tracing/shutdown-groups!)
-    ;; ... test that code still works, no wrapping applied ...
-    ))
-```
-
-### 6. Lint and run tests
-
-```bash
-# Lint modified source and test files — expect 0 errors, 0 warnings
-clj-kondo --lint path/to/modified/file.clj path/to/test/file.clj
-
-# Run tests (requires Java 21+)
-  clojure -X:dev:test :only my-ns.test-ns
-```
-
-Expect: all tests pass, 0 failures, 0 errors, no reflection warnings from your files.
-
-## Sanitizing SQL for Attributes
-
-When including SQL in span attributes, **always** use `tracing/best-effort-sanitize-sql`. This converts HoneySQL maps to parameterized SQL strings where values become `?` placeholders -- no data leaks.
-
-```clojure
-(let [hsql {:delete-from [:core_session]
-            :where [:< :created_at some-timestamp]}]
-  (tracing/with-span :tasks "task.cleanup.delete"
-                     {:db/statement (tracing/best-effort-sanitize-sql hsql)}
-    (t2/query-one hsql)))
-;; Trace attribute: db/statement = "DELETE FROM core_session WHERE created_at < ?"
-```
-
-**Rules:**
-- Never put raw SQL strings or user-provided values in attributes
-- Use `best-effort-sanitize-sql` only for app DB (HoneySQL) queries
-- For external/user DB queries, trace only timing and counts, not SQL content
-
-## Defjob and Root Spans
-
-The `defjob` macro in `metabase.task.impl` automatically wraps every Quartz job with a `:tasks` root span:
-
-```clojure
-(task/defjob ^{DisallowConcurrentExecution true} SessionCleanup [_]
-  (cleanup-sessions!))
-;; Automatically creates span: "task.SessionCleanup" {:task/name "SessionCleanup"}
-```
-
-You do NOT need a root span inside `defjob` bodies. Add **child spans** for I/O inside the job.
-
-For code on plain `Thread`s (not Quartz), add the root span manually:
-
-```clojure
-(defn init! []
-  (tracing/with-span :search "search.task.init" {}
-    (search/init-index!)))
-```
-
-## What NOT to Do
-
-### Span Usage Mistakes
-
-```clojure
-;; WRONG - pure computation, no I/O
-(tracing/with-span :search "search.format-results" {}
-  (map format-result results))
-
-;; WRONG - trivial single-row lookup
-(tracing/with-span :db-app "db-app.get-setting" {}
-  (t2/select-one :model/Setting :key "my-setting"))
-
-;; WRONG - raw SQL in attributes (data leak)
-(tracing/with-span :tasks "task.cleanup" {:db/statement raw-sql-string}
-  (execute! raw-sql-string))
-
-;; WRONG - wrong group (search work should use :search, not :tasks)
-(tracing/with-span :tasks "search.execute" {} ...)
-
-;; WRONG - redundant nesting (do-search already has a span)
-(tracing/with-span :search "search.process" {}
-  (let [results (do-search ctx)]
-    (tracing/with-span :search "search.format" {}
-      (format-results results))))
-```
-
-### Architecture Mistakes
-
-```clojure
-;; WRONG - creating a new tracing namespace
-(ns metabase.tracing.my-feature ...)
-
-;; WRONG - requiring internal tracing namespaces from outside the module
-(ns metabase.my-module.thing
-  (:require [metabase.tracing.attributes :as trace-attrs]      ;; internal!
-            [metabase.tracing.settings :as tracing.settings]   ;; internal!
-            [metabase.tracing.quartz :as tracing.quartz]))     ;; internal!
-
-;; WRONG - adding compile-time requires to tracing/core.clj for settings or SDK
-;; This creates cyclic load dependencies because tracing/core is widely required
-(ns metabase.tracing.core
-  (:require [metabase.tracing.settings :as settings]))  ;; causes cycle!
-
-;; WRONG - dynamic symbol construction with requiring-resolve (kondo rejects it)
-(requiring-resolve (symbol "metabase.tracing.settings" "tracing-enabled"))
-```
-
-## Configuration
-
-All settings are env-var-only (defined in `src/metabase/tracing/settings.clj`):
-
-```bash
-# Core
-MB_TRACING_ENABLED=true              # Enable tracing (default: false)
-MB_TRACING_ENDPOINT=host:4317        # OTLP collector endpoint (default: http://localhost:4317)
-MB_TRACING_GROUPS=tasks,search,sync  # Comma-separated groups or "all" (default: all)
-MB_TRACING_SERVICE_NAME=metabase     # Service name in traces (default: hostname)
-MB_TRACING_LOG_LEVEL=DEBUG           # Log threshold for traced threads: TRACE/DEBUG/INFO (default: INFO)
-
-# Batch span processor tuning
-MB_TRACING_MAX_QUEUE_SIZE=2048       # Max spans queued for export; drops when full (default: 2048)
-MB_TRACING_EXPORT_TIMEOUT_MS=10000   # Max wait for batch export to complete (default: 10000)
-MB_TRACING_SCHEDULE_DELAY_MS=5000    # Delay between consecutive batch exports (default: 5000)

-description: Evaluate Clojure code via nREPL using clj-nrepl-eval. Use this when you need to test code, check if edited files compile, verify function behavior, or interact with a running REPL session.
----
-
-# Clojure REPL Evaluation
-
-## When to Use This Skill
-
-Use this skill when you need to:
-- **Verify that edited Clojure files compile and load correctly**
-- Test function behavior interactively
-- Check the current state of the REPL
-- Debug code by evaluating expressions
-- Require or load namespaces for testing
-- Validate that code changes work before committing
-
-## How It Works
-
-The `clj-nrepl-eval` command evaluates Clojure code against an nREPL server. **Session state persists between evaluations**, so you can require a namespace in one evaluation and use it in subsequent calls. Each host:port combination maintains its own session file.
-
-## Instructions
-
-### 0. Discover and select nREPL server
-
-First, discover what nREPL servers are running in the current directory:
-
-```bash
-clj-nrepl-eval --discover-ports
-```
-
-This will show all nREPL servers (Clojure, Babashka, shadow-cljs, etc.) running in the current project directory.
-
-**Then use the AskUserQuestion tool:**
-
-- **If ports are discovered:** Prompt user to select which nREPL port to use:
-  - **question:** "Which nREPL port would you like to use?"
-  - **header:** "nREPL Port"
-  - **options:** Present each discovered port as an option with:
-    - **label:** The port number
-    - **description:** The server type and status (e.g., "Clojure nREPL server in current directory")
-  - Include up to 4 discovered ports as options
-  - The user can select "Other" to enter a custom port number
-
-- **If no ports are discovered:** Prompt user how to start an nREPL server:
-  - **question:** "No nREPL servers found. How would you like to start one?"
-  - **header:** "Start nREPL"
-  - **options:**
-    - **label:** "deps.edn alias", **description:** "Find and use an nREPL alias in deps.edn"
-    - **label:** "Leiningen", **description:** "Start nREPL using 'lein repl'"
-  - The user can select "Other" for alternative methods or if they already have a server running on a specific port
-
-IMPORTANT: IF you start a REPL do not supply a port let the nREPL start and return the port that it was started on.
-
-### 1. Evaluate Clojure Code
-
-> Evaluation automatically connects to the given port
-
-Use the `-p` flag to specify the port and pass your Clojure code.
-
-**Recommended: Pass code as a command-line argument:**
-```bash
-clj-nrepl-eval -p <PORT> "(+ 1 2 3)"
-```
-
-**For multiple expressions (single line):**
-```bash
-clj-nrepl-eval -p <PORT> "(def x 10) (+ x 20)"
-```
-
-**Alternative: Using heredoc (may require permission approval for multiline commands):**
-```bash
-clj-nrepl-eval -p <PORT> <<'EOF'
-(def x 10)
-(+ x 20)
-EOF
-```
-
-**Alternative: Via stdin pipe:**
-```bash
-echo "(+ 1 2 3)" | clj-nrepl-eval -p <PORT>
-```
-
-### 2. Display nREPL Sessions
-
-**Discover all nREPL servers in current directory:**
-```bash
-clj-nrepl-eval --discover-ports
-```
-Shows all running nREPL servers in the current project directory, including their type (clj/bb/basilisp) and whether they match the current working directory.
-
-**Check previously connected sessions:**
-```bash
-clj-nrepl-eval --connected-ports
-```
-Shows only connections you have made before (appears after first evaluation on a port).
-
-### 3. Common Patterns
-
-**Require a namespace (always use :reload to pick up changes):**
-```bash
-clj-nrepl-eval -p <PORT> "(require '[my.namespace :as ns] :reload)"
-```
-
-**Test a function after requiring:**
-```bash
-clj-nrepl-eval -p <PORT> "(ns/my-function arg1 arg2)"
-```
-
-**Check if a file compiles:**
-```bash
-clj-nrepl-eval -p <PORT> "(require 'my.namespace :reload)"
-```
-
-**Multiple expressions:**
-```bash
-clj-nrepl-eval -p <PORT> "(def x 10) (* x 2) (+ x 5)"
-```
-
-**Complex multiline code (using heredoc):**
-```bash
-clj-nrepl-eval -p <PORT> <<'EOF'
-(def x 10)
-(* x 2)
-(+ x 5)
-EOF
-```
-*Note: Heredoc syntax may require permission approval.*
-
-**With custom timeout (in milliseconds):**
-```bash
-clj-nrepl-eval -p <PORT> --timeout 5000 "(long-running-fn)"
-```
-
-**Reset the session (clears all state):**
-```bash
-clj-nrepl-eval -p <PORT> --reset-session
-clj-nrepl-eval -p <PORT> --reset-session "(def x 1)"
-```
-
-## Available Options
-
-- `-p, --port PORT` - nREPL port (required)
-- `-H, --host HOST` - nREPL host (default: 127.0.0.1)
-- `-t, --timeout MILLISECONDS` - Timeout (default: 120000 = 2 minutes)
-- `-r, --reset-session` - Reset the persistent nREPL session
-- `-c, --connected-ports` - List previously connected nREPL sessions
-- `-d, --discover-ports` - Discover nREPL servers in current directory
-- `-h, --help` - Show help message
-
-## Important Notes
-
-- **Prefer command-line arguments:** Pass code as quoted strings: `clj-nrepl-eval -p <PORT> "(+ 1 2 3)"` - works with existing permissions
-- **Heredoc for complex code:** Use heredoc (`<<'EOF' ... EOF`) for truly multiline code, but note it may require permission approval
-- **Sessions persist:** State (vars, namespaces, loaded libraries) persists across invocations until the nREPL server restarts or `--reset-session` is used
-- **Automatic delimiter repair:** The tool automatically repairs missing or mismatched parentheses
-- **Always use :reload:** When requiring namespaces, use `:reload` to pick up recent changes
-- **Default timeout:** 2 minutes (120000ms) - increase for long-running operations
-- **Input precedence:** Command-line arguments take precedence over stdin
-
-## Typical Workflow
-
-1. Discover nREPL servers: `clj-nrepl-eval --discover-ports`
-2. Use **AskUserQuestion** tool to prompt user to select a port
-3. Require namespace:
-   ```bash
-   clj-nrepl-eval -p <PORT> "(require '[my.ns :as ns] :reload)"
-   ```
-4. Test function:
-   ```bash
-   clj-nrepl-eval -p <PORT> "(ns/my-fn ...)"
-   ```
-5. Iterate: Make changes, re-require with `:reload`, test again

-
-# Code-Reading-First → Generate Cypress Tests (Metabase)
-
-You are writing Cypress E2E tests for the **Metabase** codebase.
-Before generating ANY test code, you MUST analyze React component source code
-to understand DOM structure, selectors, and user flows.
-
-## Phase 0 — Research
-
-1. Read existing helpers before writing anything:
-   - `e2e/support/helpers/` — all shared helpers (restore, signInAs, openOrdersTable, etc.)
-   - `e2e/support/cypress_sample_database.ts` — table/field schema constants (ORDERS, PRODUCTS, etc.)
-   - `e2e/support/cypress_sample_instance_data.ts` — instance-specific IDs (ORDERS_DASHBOARD_ID, NORMAL_USER_ID, etc.)
-2. Glob `e2e/test/scenarios/` to find the closest existing spec to the area under test.
-   Study its patterns — match them exactly.
-3. Glob `frontend/src/metabase/` to find React components for the feature area.
-
-## Phase 1 — Code Analysis
-
-Read React component source to understand DOM structure. No browser needed — source code has everything.
-
-1. **Find relevant components**: Glob and grep `frontend/src/metabase/` for the feature area.
-2. **Extract selectors**: Grep for `data-testid` in relevant components.
-3. **Note visible text**: Read component JSX for button labels, headings, placeholders.
-4. **Note aria attributes**: Grep for `aria-label` in relevant components.
-5. **Understand user flows**: Read event handlers (onClick, onSubmit, onChange) to understand interactions.
-6. **Find API calls**: Grep for `Api.use`, `fetch`, `useQuery`, endpoint definitions to identify API calls to intercept.
-7. **Cross-reference with existing specs**: Find specs in the same area and reuse their proven selectors and `cy.intercept` patterns.
-
-## Phase 2 — Start Backend
-
-Use `MB_EDITION=oss` by default. Only use `MB_EDITION=ee` when the user explicitly asks to write an enterprise test.
-
-Start the backend using `run_in_background: true` (NOT `&`).
-`bin/e2e-backend` automatically detects if a backend is already running and reuses it.
-```bash
-MB_EDITION=oss bin/e2e-backend
-```
-
-Do NOT manually generate snapshots by running unrelated test specs.
-The `bun test-cypress` runner has `GENERATE_SNAPSHOTS: true` by default and automatically
-generates snapshots before running any spec. When running tests in Phase 4 via the `/e2e-test` skill,
-snapshots will be generated on the first run if they don't already exist.
-
-Restore clean test data:
-```bash
-curl -sf -X POST http://localhost:4000/api/testing/restore/default
-```
-
-## Phase 3 — Generate Cypress Spec
-
-### File location & naming
-
-Place specs in `e2e/test/scenarios/<area>/` mirroring the URL structure.
-Name: `<feature>.cy.spec.js` (NOT `.cy.spec.ts`).
-
-### Metabase conventions (mandatory)
-
-- **Helpers via `cy.H`**: All helpers are accessed via `const { H } = cy;` — NOT via direct imports from `e2e/support/helpers`.
-
-```js
-const { H } = cy;
-
-describe("feature name", () => {
-  beforeEach(() => {
-    H.restore();
-    cy.signInAsAdmin();
-  });
-});
-```
-
-- **Sample Database schema** (table/field definitions): Import from `cypress_sample_database`.
-
-```js
-import { ORDERS, ORDERS_ID, PRODUCTS } from "e2e/support/cypress_sample_database";
-```
-
-- **Instance data** (dashboard IDs, user IDs, etc.): Import from `cypress_sample_instance_data`.
-
-```js
-import { ORDERS_DASHBOARD_ID } from "e2e/support/cypress_sample_instance_data";
-```
-
-- **Selectors** (priority order):
-  1. `cy.findByText()` / `cy.findByLabelText()` / `cy.findByRole()` — from `@testing-library/cypress`
-  2. `cy.findByTestId()` — for `data-testid` attributes
-  3. `cy.get("[data-testid='...']")` — fallback
-  4. NEVER use positional selectors, CSS class names, or XPaths.
-
-- **Navigation helpers**: Use existing helpers like `H.openOrdersTable()`, `H.openNativeEditor()`,
-  `H.visitDashboard(id)`, `H.visitQuestion(id)` instead of raw `cy.visit()` chains.
-  Grep `e2e/support/helpers/` to discover what's available for your area.
-
-- **API setup over UI setup**: Use `cy.request()` or existing API helpers to set up state.
-  Only use the UI for the flow you're actually testing.
-
-- **Assertions**: Assert on visible text, URL, aria state — not DOM structure.
-
-- **Waits**: Never use `cy.wait(ms)`. Use `cy.intercept()` + `cy.wait("@alias")` for API calls,
-  or `cy.findByText().should("be.visible")` for DOM readiness.
-
-- **Isolation**: Each `it()` block must be independently runnable.
-  Don't depend on state from a previous `it()`.
-
-### Spec structure template
-
-```js
-const { H } = cy;
-import { ORDERS_DASHBOARD_ID } from "e2e/support/cypress_sample_instance_data";
-import { ORDERS, ORDERS_ID } from "e2e/support/cypress_sample_database";
-
-describe("area > sub-area > feature (#issue-number)", () => {
-  beforeEach(() => {
-    H.restore();
-    cy.signInAsAdmin();
-  });
-
-  it("should do the primary happy-path thing", () => {
-    // test
-  });
-
-  it("should handle the edge case", () => {
-    // test
-  });
-});
-```
-
-### Intercepts
-
-When you identified API calls during code analysis, stub or wait on them:
-
-```js
-cy.intercept("POST", "/api/dataset").as("dataset");
-// ... trigger action ...
-cy.wait("@dataset");
-```
-
-## Phase 4 — Validate
-
-After generating specs:
-1. Check that all imported helpers exist (Grep `e2e/support/helpers/`).
-2. **You MUST use the `/e2e-test` skill** to run tests — do NOT run `bun test-cypress` directly.
-   The `/e2e-test` skill handles edition selection, snapshot management, and correct env vars.
-   `/e2e-test GREP="should do the thing" --spec e2e/test/scenarios/<path>`
-   If you created multiple `it()` blocks, run each one individually to isolate failures.
-
-## Phase 5 — Fix Failures (up to 2 attempts)
-
-When a test fails, **try to fix it from Cypress output first**:
-1. Read the failure screenshot (path printed under `(Screenshots)`).
-2. Read the error message and code frame from the console output.
-3. Fix the test and re-run (back to Phase 4, step 2).
-
-If you cannot diagnose the issue after 2 attempts, proceed to Phase 6.
-
-## Phase 6 — Playwright Fallback
-
-Only reach this phase after 2 failed fix attempts from Phase 5. The backend is already running.
-
-Restore clean test data:
-```bash
-curl -sf -X POST http://localhost:4000/api/testing/restore/default
-```
-
-**Bypass CSP** headers before navigating (Metabase serves strict CSP that blocks dev server scripts).
-Use `browser_run_code` to set this up:
-
-```js
-async (page) => {
-  // Strip CSP headers so the page loads (mirrors Cypress chromeWebSecurity: false)
-  await page.context().route('**/*', async (route) => {
-    const response = await route.fetch();
-    const headers = { ...response.headers() };
-    delete headers['content-security-policy'];
-    delete headers['content-security-policy-report-only'];
-    await route.fulfill({ response, headers });
-  });
-
-  // Sign in via API
-  const response = await page.request.post('http://localhost:4000/api/session', {
-    data: { username: 'admin@metabase.test', password: '12341234' }
-  });
-  const session = await response.json();
-  await page.context().addCookies([{
-    name: 'metabase.DEVICE',
-    value: session.id,
-    domain: 'localhost',
-    path: '/'
-  }]);
-
-  await page.goto('http://localhost:4000');
-  await page.waitForLoadState('networkidle');
-  return 'signed in';
-}
-```
-
-**Maintain an observation log incrementally.** After EVERY significant Playwright interaction,
-IMMEDIATELY append what you observed to the scratch file BEFORE performing the next interaction:
-
-```bash
-cat >> /tmp/e2e-observations.md << 'OBSERVATION'
-## [Page/Flow name]
-- URL: /question/notebook#...
-- Clicked: "Box plot" button → visible text "Box plot", role: radio
-- Selectors: data-testid="viz-type-button", findByText("Box plot")
-- API call: POST /api/dataset (triggered on viz change)
-- Key state: after selecting viz type, summary sidebar shows metric picker
-OBSERVATION
-```
-
-For each page/flow:
-- Take an accessibility snapshot (`browser_snapshot`).
-- Click through interactive elements, fill forms, trigger modals.
-- **Append to the observation log immediately after each step**: URLs, visible text, aria labels, `data-testid` attrs, API calls.
-- Screenshot key states.
-
-After exploration:
-1. Read back your observation log: `cat /tmp/e2e-observations.md`
-2. Fix the test using observed selectors and behavior.
-3. Re-run the test (back to Phase 4).
-4. Clean up: `rm -f /tmp/e2e-observations.md`
-
-## Phase 7 — Cleanup
-
-After all tests pass (or after giving up on fixing failures), **always kill the backend on port 4000**:
-```bash
-lsof -ti:4000 | xargs kill 2>/dev/null || true
-```
-
-Do NOT use broad `pkill` patterns — there may be other Metabase instances on different ports.
-The backend process started in Phase 2 will NOT be killed automatically when the Claude session ends.
-Leaving it running wastes resources and can interfere with future sessions. Always clean up.
-
-## What NOT to do
-
-- Do NOT use Playwright as the first step — always analyze source code first.
-- Do NOT kill the backend between phases — it stays running throughout.
-- Do NOT invent selectors you didn't find in source code or observe in the browser.
-- Do NOT hardcode database IDs — import from `cypress_sample_database` or `cypress_sample_instance_data`.
-- Do NOT use `cy.wait(1000)` or any numeric wait.
-- Do NOT create setup flows through the UI when an API helper exists.
-- Do NOT put tests in `cypress/e2e/` — Metabase uses `e2e/test/scenarios/`.
-- Do NOT import helpers directly from `e2e/support/helpers` — use `const { H } = cy;`.

-**Default: `MB_EDITION=oss`** — runs without enterprise tokens, simpler and faster.
-
-Only use `MB_EDITION=ee` when the user explicitly asks to write or run an enterprise test.
-
-**For `MB_EDITION=ee`:**
-These tokens must be exported in the shell before starting Claude Code:

-# Emotion → Mantine + CSS Modules Migration Skill
-
-Migrate Emotion styled-components (`@emotion/styled`, `@emotion/react`) to Mantine layout components with style props and CSS modules. The goal is zero Emotion imports, zero inline styles, and maximum use of design system tokens.
-
-## Priority Order (Strict)
-
-1. **Mantine components + style props** — `Box`, `Flex`, `Stack`, `Group`, `Text`, `Title`, `Card`. This is the DEFAULT. Every CSS property must be checked against style props FIRST.
-2. **CSS modules** (`.module.css`) — ONLY for properties that Mantine style props genuinely cannot express: pseudo-selectors (`:hover`, `:focus`, `::before`), `box-shadow`, `border` shorthand, `animation`/`@keyframes`, complex selectors, `cursor`, `pointer-events`, `overflow`, `text-overflow`, `white-space`, `transition`.
-3. **Inline styles ONLY for dynamic values** — `style={{ }}` is allowed only for truly dynamic runtime values (e.g., computed widths, positions, data-driven colors). All static styles must use Mantine props or CSS modules.
-
-### Mantine-First Decision Gate (CRITICAL)
-
-For EACH styled component, go through every CSS property and ask: "Can this be a Mantine style prop?" If yes → style prop. If no → CSS module. Do NOT dump an entire component into a CSS module just because one property needs it — split them.
-
-**Properties that ARE style props** (use these, not CSS modules):
-
-- `display` → `display` prop
-- `color` → `c` prop (`c="brand"`, `c="text-primary"`)
-- `background-color` → `bg` prop (`bg="background-primary"`)
-- `font-size` → `fz` prop (`fz="md"`)
-- `font-weight` → `fw` prop (`fw="bold"`)
-- `line-height` → `lh` prop (`lh="md"`)
-- `text-align` → `ta` prop (`ta="center"`)
-- `padding` (all variants) → `p`, `px`, `py`, `pt`, `pb`, `pl`, `pr`
-- `margin` (all variants) → `m`, `mx`, `my`, `mt`, `mb`, `ml`, `mr`
-- `width` → `w`, `min-width` → `miw`, `max-width` → `maw`
-- `height` → `h`, `min-height` → `mih`, `max-height` → `mah`
-- `flex` → `flex` prop (`flex="0 0 auto"`, `flex={1}`)
-- `gap` → `gap` prop (on Flex/Stack/Group)
-- `align-items` → `align` prop (on Flex/Stack/Group)
-- `justify-content` → `justify` prop (on Flex/Stack/Group)
-- `flex-direction` → `direction` prop (on Flex)
-- `flex-wrap` → `wrap` prop (on Flex)
-- `position` → `pos` prop
-- `top/right/bottom/left` → `top`, `right`, `bottom`, `left` props
-- `opacity` → `opacity` prop
-
-**Properties that NEED CSS modules** (no style prop equivalent):
-
-- `:hover`, `:focus`, `:active`, `::before`, `::after` (pseudo-selectors)
-- `box-shadow`, `border` (shorthand with color), `outline`
-- `cursor`, `pointer-events`
-- `overflow`, `text-overflow`, `white-space`
-- `animation`, `transition`, `transform`
-- `@media` queries (UNLESS it's simple responsive spacing/sizing — then use responsive syntax: `p={{ base: "md", lg: "xl" }}`)
-
-**Hybrid approach** — when a component needs BOTH, put style props on the Mantine component AND add a CSS module class for the rest:
-
-```tsx
-<Flex
-  className={S.root}       /* for :hover, box-shadow, border */
-  align="center"            /* style prop */
-  gap="sm"                  /* style prop */
-  p="md"                    /* style prop */
-  bg="background-primary"   /* style prop */
->
-```
-
-## CSS Module Conventions (Strict)
-
-### Class Naming: camelCase
-
-All CSS module class names MUST use **camelCase**. This is the dominant convention across the codebase (~830 camelCase vs ~620 PascalCase classes), used consistently in Mantine UI components, and matches standard CSS module conventions.
-
-```css
-/* CORRECT */
-.root {
-}
-.settingsSection {
-}
-.dragHandle {
-}
-.closeIcon {
-}
-
-/* WRONG — do not use PascalCase or kebab-case */
-.ItemRoot {
-}
-.settings-section {
-}
-```
-
-Modifier/state classes also use camelCase:
-
-```css
-.selected {
-}
-.disabled {
-}
-.interactive {
-}
-.draggable {
-}
-```
-
-### No Cascading — Direct Class Assignment
-
-Cascading selectors are **discouraged**. Instead of styling through parent-child relationships, assign a class directly to the element that needs styling.
-
-```css
-/* WRONG — cascading/descendant selectors */
-.root > input {
-}
-.root .label {
-}
-.container > div > span {
-}
-
-/* CORRECT — direct class on the target element */
-.input {
-}
-.label {
-}
-.title {
-}
-```
-
-The only acceptable nesting patterns are:
-
-- **Pseudo-selectors on the same element**: `.item { &:hover { } }`
-- **Modifier composition**: `.item { &.selected { } }`
-- **Hover-reveal patterns** where a parent hover affects a child: `.root:hover .showOnHover { opacity: 1; }` — but only when structurally necessary (the child has no way to know about the parent's hover state)
-
-### Import Alias
-
-Always import the CSS module as `S`:
-
-```tsx
-import S from "./ComponentName.module.css";
-```
-
-## Step-by-Step Migration Process
-
-### Step 1: Read and Understand
-
-Read the `.styled.tsx` file AND every component that imports from it. Understand:
-
-- Which styled components are used and where
-- Which props drive dynamic styles
-- Which styles are static vs conditional
-- Which styles can map directly to Mantine style props
-
-### Step 2: Classify Each Styled Component
-
-For each styled component, apply the Mantine-First Decision Gate above. Then determine the migration target:
-
-| Emotion Pattern                                              | Migration Target                                                                                                                                                           |
-| ------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `styled.div` with only layout/spacing/color                  | `Box`, `Flex`, `Stack`, or `Group` with style props. **NO CSS module needed.**                                                                                             |
-| `styled.div` with flexbox column                             | `Stack` component with style props                                                                                                                                         |
-| `styled.div` with flexbox row                                | `Flex` or `Group` component with style props                                                                                                                               |
-| `styled.span` / `styled.p` with color/weight/size            | **`Text component="span"` with style props** (`c`, `fw`, `fz`). NO CSS module.                                                                                             |
-| `styled.div` with hover/focus/pseudo-selectors               | **Hybrid**: Mantine component with style props for expressible properties + CSS module class for pseudo-selectors only                                                     |
-| `styled.div` with media queries (simple spacing/sizing)      | **Responsive style props**: `p={{ base: "md", lg: "xl" }}`. NO CSS module.                                                                                                 |
-| `styled.div` with media queries (complex/non-spacing)        | CSS module for the media query parts, style props for the rest                                                                                                             |
-| `styled.div` with animations/keyframes                       | CSS module for animation, style props for layout                                                                                                                           |
-| `styled(SomeComponent)` with only color/spacing/flex         | **Wrap in Mantine component** with style props: `<Box c="brand" flex="0 0 auto"><Icon /></Box>`, or pass style props if the component accepts them                         |
-| `styled(SomeComponent)` with pseudo-selectors/complex styles | CSS module `className` on the component                                                                                                                                    |
-| Dynamic props `styled.div<{ isActive: boolean }>`            | Mantine style props for simple toggles (`c={active ? "brand" : "text-primary"}`), `cx()` with CSS module classes for complex state combinations involving pseudo-selectors |
-
-### Step 3: Create CSS Module (if needed)
-
-Create `ComponentName.module.css` alongside the component file:
-
-```css
-/* Use design system tokens — NEVER raw color/spacing values */
-.root {
-  border: 1px solid var(--mb-color-border);
-  border-radius: var(--mantine-radius-md);
-  background-color: var(--mb-color-background-primary);
-}
-
-/* Conditional states as separate classes, combined with cx() */
-.active {
-  background-color: var(--mb-color-brand);
-  color: var(--mb-color-text-primary-inverse);
-}
-
-.disabled {
-  color: var(--mb-color-text-tertiary);
-  pointer-events: none;
-}
-
-/* Hover/focus/pseudo-selectors — nest with & */
-.interactive {
-  cursor: pointer;
-
-  &:hover {
-    color: var(--mb-color-brand);
-    background-color: var(--mb-color-background-hover);
-  }
-}
-
-/* Hover-reveal: acceptable parent→child nesting */
-.root:hover .showOnHover {
-  opacity: 1;
-}
-
-/* Responsive styles */
-@media (--breakpoint-min-md) {
-  .root {
-    padding: var(--mantine-spacing-lg);
-  }
-}
-```
-
-### Step 4: Update the Component TSX
-
-```tsx
-import cx from "classnames";
-import CS from "metabase/css/core/index.css";
-import { Box, Flex, Group, Stack, Text } from "metabase/ui";
-import S from "./ComponentName.module.css";
-
-// Dynamic props → cx() with conditional classes
-<Flex
-  className={cx(S.root, {
-    [S.active]: isActive,
-    [S.disabled]: disabled,
-  })}
-  align="center"
-  gap="sm"
-  p="md"
-  w="100%"
->
-```
-
-### Step 5: Delete the `.styled.tsx` File
-
-Remove the old styled file entirely. Remove all imports of it from other files.
-
-### Step 6: Verify
-
-- Confirm zero `@emotion/styled` or `@emotion/react` imports remain in the migrated files
-- Confirm no static inline styles (dynamic runtime values are fine)
-- Confirm all colors use tokens, not raw hex/rgb values
-
-## Design System Token Reference
-
-### Mantine Style Props (use directly on components)
-
-**Spacing** (`p`, `px`, `py`, `pt`, `pb`, `pl`, `pr`, `m`, `mx`, `my`, `mt`, `mb`, `ml`, `mr`):
-
-- `"xs"` = 4px, `"sm"` = 8px, `"md"` = 16px, `"lg"` = 24px, `"xl"` = 32px
-- Custom: `rem(48)` for non-standard values (import `rem` from `metabase/ui`)
-
-**Dimensions** (`w`, `h`, `maw`, `mah`, `miw`, `mih`):
-
-- `"100%"`, `"100vh"`, `rem(400)`, etc.
-
-**Colors** (`c`, `bg`):
-
-- Text: `"text-primary"`, `"text-secondary"`, `"text-tertiary"`
-- Background: `"background-primary"`, `"background-secondary"`, `"background-hover"`

-- Font weight: `"bold"`, `"normal"`, or numeric `700`
-- Line height: `"xs"` = 100%, `"sm"` = 115%, `"md"` = 122%, `"lg"` = 138%, `"xl"` = 150%
-- Text align: `"center"`, `"left"`, `"right"`
-
-**Flexbox** (`align`, `justify`, `gap`, `direction`, `wrap`, `flex`):
-
-- `align="center"`, `justify="space-between"`, `gap="sm"`, `direction="column"`, `wrap="nowrap"`
-- `flex={1}`, `flex="0 0 auto"`
-
-**Other**: `pos` (position), `display`
-
-**Responsive syntax**: `px={{ base: "md", md: "lg", lg: rem(48) }}`
-
-### CSS Variable Tokens (use in `.module.css` files)
-
-**Colors** — `var(--mb-color-<name>)`:
-
-- `--mb-color-text-primary`, `--mb-color-text-secondary`, `--mb-color-text-tertiary`
-- `--mb-color-background-primary`, `--mb-color-background-secondary`, `--mb-color-background-hover`

-
-**Breakpoints** (in `.module.css` files):
-
-- `@media (--breakpoint-min-sm)` (40em / 640px)
-- `@media (--breakpoint-min-md)` (60em / 960px)
-- `@media (--breakpoint-min-lg)` (80em / 1280px)
-- `@media (--breakpoint-min-xl)` (120em / 1920px)
-- Also available: `--breakpoint-max-*` variants
-
-### Snap Hardcoded Literals to Nearest Design Token (CRITICAL)
-
-When migrating, **never carry over hardcoded `rem`/`px` values** from the original Emotion code. Instead, snap them to the nearest design system token. The original values were often arbitrary — the migration is an opportunity to align with the design system.
-
-**Spacing** — snap to the nearest Mantine spacing token:
-
-| Hardcoded value                   | Nearest token | Style prop   | CSS variable                   |
-| --------------------------------- | ------------- | ------------ | ------------------------------ |
-| `0.125rem` (2px)                  | `2px`         | `2` (number) | `2px` (keep literal, no token) |
-| `0.2rem` (3.2px), `0.25rem` (4px) | **xs** (4px)  | `"xs"`       | `var(--mantine-spacing-xs)`    |
-| `0.5rem` (8px)                    | **sm** (8px)  | `"sm"`       | `var(--mantine-spacing-sm)`    |
-| `0.75rem` (12px)                  | between sm/md | `rem(12)`    | `0.75rem` (no exact token)     |
-| `1rem` (16px)                     | **md** (16px) | `"md"`       | `var(--mantine-spacing-md)`    |
-| `1.5rem` (24px)                   | **lg** (24px) | `"lg"`       | `var(--mantine-spacing-lg)`    |
-| `2rem` (32px)                     | **xl** (32px) | `"xl"`       | `var(--mantine-spacing-xl)`    |
-
-**Border radius** — snap to the nearest Mantine radius token:
-
-| Hardcoded value  | Nearest token                 | CSS variable               |
-| ---------------- | ----------------------------- | -------------------------- |
-| `0.25rem` (4px)  | **xs** (4px)                  | `var(--mantine-radius-xs)` |
-| `0.375rem` (6px) | **sm** (6px)                  | `var(--mantine-radius-sm)` |
-| `0.5rem` (8px)   | **md** (8px)                  | `var(--mantine-radius-md)` |
-| `1rem`+ (16px+)  | **xl** (40px) or keep literal | `var(--mantine-radius-xl)` |
-
-**Font sizes** — snap to the nearest Mantine font size token:
-
-| Hardcoded value                  | Nearest token | Style prop | CSS variable                  |
-| -------------------------------- | ------------- | ---------- | ----------------------------- |
-| `0.6875rem` (11px)               | **xs** (11px) | `fz="xs"`  | `var(--mantine-font-size-xs)` |
-| `0.75rem` (12px)                 | **sm** (12px) | `fz="sm"`  | `var(--mantine-font-size-sm)` |
-| `0.875rem` (14px), `1rem` (16px) | **md** (14px) | `fz="md"`  | `var(--mantine-font-size-md)` |
-| `1.063rem` (17px)                | **lg** (17px) | `fz="lg"`  | `var(--mantine-font-size-lg)` |
-| `1.3rem` (21px)                  | **xl** (21px) | `fz="xl"`  | `var(--mantine-font-size-xl)` |
-
-**Rules:**
-
-- If the hardcoded value is within ~2px of a token, use the token
-- If it falls exactly between two tokens, prefer the smaller one (tighter is safer)
-- If no token is close (e.g., `48px` spacing), use `rem(48)` for style props or the literal value in CSS modules
-- This applies everywhere: style props, CSS module values, Icon `size` props, etc.

-## Common Migration Patterns
-
-### Pattern 1: Static Layout Container → Mantine Component
-
-**Before:**
-
-```tsx
-// Component.styled.tsx
-export const Container = styled.div`
-  display: flex;
-  align-items: center;
-  gap: 0.5rem;
-  padding: 1rem;
-  width: 100%;
-`;
-```
-
-**After:**
-
-```tsx
-<Flex align="center" gap="sm" p="md" w="100%">
-```
-
-### Pattern 2: Vertical Stack → Stack Component
-
-**Before:**
-
-```tsx
-export const Wrapper = styled.div`
-  display: flex;
-  flex-direction: column;
-  gap: 1.5rem;
-  padding: 2rem;
-`;
-```
-
-**After:**
-
-```tsx
-<Stack gap="lg" p="xl">
-```
-
-### Pattern 3: Dynamic Props → cx() with CSS Module Classes
-
-**Before:**
-
-```tsx
-export const Item = styled.div<{ isSelected: boolean; disabled: boolean }>`
-  color: ${(props) =>
-    props.disabled ? color("text-tertiary") : color("text-primary")};
-  background-color: ${(props) =>
-    props.isSelected ? color("brand") : "transparent"};
-  cursor: ${(props) => (props.disabled ? "default" : "pointer")};
-
-  &:hover {
-    color: ${(props) => !props.disabled && color("brand")};
-  }
-`;
-```
-
-**After (CSS module):**
-
-```css
-/* Item.module.css */
-.itemRoot {
-  color: var(--mb-color-text-primary);
-  cursor: pointer;
-
-  &:hover {
-    color: var(--mb-color-brand);
-  }
-}
-
-.selected {
-  background-color: var(--mb-color-brand);
-}
-
-.disabled {
-  color: var(--mb-color-text-tertiary);
-  cursor: default;
-
-  &:hover {
-    color: var(--mb-color-text-tertiary);
-  }
-}
-```
-
-**After (TSX):**
-
-```tsx
-<Box
-  className={cx(S.itemRoot, {
-    [S.selected]: isSelected,
-    [S.disabled]: disabled,
-  })}
->
-```
-
-### Pattern 4: Extending a Component → Style Props First, CSS Module Only If Needed
-
-When a styled component wraps another component, first check if the styles can be expressed as style props on a Mantine wrapper or on the component itself. Only use a CSS module when properties genuinely need it.
-
-**Before:**
-
-```tsx
-export const CardIcon = styled(Icon)`
-  display: block;
-  flex: 0 0 auto;
-  color: var(--mb-color-brand);
-`;
-
-export const CardTitle = styled(Ellipsified)`
-  color: var(--mb-color-text-primary);
-  font-size: 1rem;
-  font-weight: bold;
-  margin-left: 1rem;
-`;
-```
-
-**After — style props on Mantine wrapper (preferred when ALL properties are expressible):**
-
-```tsx
-<Box display="block" flex="0 0 auto" c="brand">
-  <Icon {...icon} />
-</Box>
-<Box c="text-primary" fz="md" fw="bold" ml="md">
-  <Ellipsified>{title}</Ellipsified>
-</Box>
-```
-
-**After — CSS module (use only when component has pseudo-selectors or non-expressible styles):**
-
-```css
-.icon {
-  color: var(--mb-color-brand);
-  width: 1.5rem;
-  height: 1.5rem;
-  cursor: pointer;
-
-  &:hover {
-    color: var(--mb-color-brand-hover);
-  }
-}
-```
-
-```tsx
-<Icon className={S.icon} name="warning" />
-```
-
-### Pattern 4b: `styled.span` / `styled.p` with Text Styles → `Text` Component
-
-**Before:**
-
-```tsx
-export const Label = styled.span`
-  color: var(--mb-color-text-secondary);
-  font-weight: bold;
-`;
-
-export const Title = styled.span`
-  color: var(--mb-color-text-primary);
-  font-size: 1rem;
-  font-weight: bold;
-  margin-left: 0.5rem;
-`;
-```
-
-**After — `Text` component with style props (NO CSS module needed):**
-
-```tsx
-<Text component="span" c="text-secondary" fw="bold">
-  {label}
-</Text>
-
-<Text component="span" c="text-primary" fz="md" fw="bold" ml="sm">
-  {title}
-</Text>
-```
-
-`Text` renders as `<p>` by default. Use `component="span"` to render inline. All color, typography, and spacing props work directly — no CSS module needed for pure text styling.
-
-### Pattern 5: Keyframes Animation → CSS Module
-
-**Before:**
-
-```tsx
-const spin = keyframes`
-  from { transform: rotate(0deg); }
-  to { transform: rotate(360deg); }
-`;
-
-export const Spinner = styled.div`
-  animation: ${spin} 1s infinite linear;
-`;
-```
-
-**After (CSS module):**
-
-```css
-@keyframes spin {
-  from {
-    transform: rotate(0deg);
-  }
-  to {
-    transform: rotate(360deg);
-  }
-}
-
-.spinner {
-  animation: spin 1s infinite linear;
-}
-```
-
-**After (TSX):**
-
-```tsx
-<Box className={S.spinner} />
-```
-
-### Pattern 6: color() Function → CSS Variables
-
-| Emotion (JS)            | CSS Module                                                   | Mantine Style Prop          |
-| ----------------------- | ------------------------------------------------------------ | --------------------------- |
-| `color("brand")`        | `var(--mb-color-brand)`                                      | `c="brand"` or `bg="brand"` |
-| `color("text-primary")` | `var(--mb-color-text-primary)`                               | `c="text-primary"`          |
-| `color("border")`       | `var(--mb-color-border)`                                     | N/A (use CSS module)        |
-| `alpha("brand", 0.2)`   | `color-mix(in srgb, var(--mb-color-brand), transparent 80%)` | N/A (use CSS module)        |
-
-### Pattern 7: Responsive Spacing/Sizing → Responsive Style Props (NOT CSS Media Queries)
-
-When a styled component only changes spacing, sizing, or other style-prop-expressible values at breakpoints, use Mantine's responsive syntax instead of CSS module media queries.
-
-**Before:**
-
-```tsx
-export const CaptionRoot = styled.div`
-  margin-bottom: 1.5rem;
-
-  ${breakpointMinExtraLarge} {
-    margin-bottom: 2rem;
-  }
-`;
-```
-
-**After — responsive style prop (NO CSS module needed):**
-
-```tsx
-<Flex mb={{ base: "lg", xl: "xl" }}>
-```
-
-Breakpoint keys: `base` (default), `xs` (40em), `sm` (48em), `md` (60em), `lg` (80em), `xl` (120em).
-
-Only use CSS module `@media` queries when the responsive change involves non-style-prop properties (e.g., `box-shadow`, `border`, `cursor` changes at breakpoints).
-
-### Pattern 8: Dynamic Computed Styles → Inline Styles
-
-Inline styles are allowed **only** for truly dynamic values computed at runtime (e.g., widths, positions, colors from data). Everything else must use Mantine style props or CSS modules.
-
-**Before:**
-
-```tsx
-export const Bar = styled.div<{ width: number }>`
-  width: ${(props) => props.width}%;
-`;
-```
-
-**After:**
-
-```tsx
-<Box style={{ width: `${width}%` }} />
-```
-
-### Pattern 9: Core CSS Utility Classes (Discouraged)
-
-**Do NOT introduce new `CS` utility class usage.** Core CSS utilities (`CS` from `metabase/css/core/index.css`) are legacy and discouraged for new code. Prefer Mantine style props or CSS modules instead.
-
-If existing code already uses `CS` classes and you're not migrating that specific code, leave them alone. But when migrating Emotion → Mantine, replace with the proper alternative:
-
-| Instead of `CS.*`   | Use                                                     |
-| ------------------- | ------------------------------------------------------- |
-| `CS.overflowHidden` | CSS module: `overflow: hidden`                          |
-| `CS.cursorPointer`  | CSS module: `cursor: pointer`                           |
-| `CS.flex1`          | Style prop: `flex={1}`                                  |
-| `CS.flexNoShrink`   | Style prop: `flex="0 0 auto"`                           |
-| `CS.textBrandHover` | CSS module: `&:hover { color: var(--mb-color-brand); }` |
-
-### Pattern 10: Shared Emotion Styles Across Files → Shared CSS Module + cx()
-
-When Emotion exports a shared `css` block (like `animationStyles`) imported by many files, create ONE CSS module with the shared keyframe and a reusable class, then compose via `cx()`.
-
-**Before (Emotion — shared animation used by 13+ skeleton files):**
-
-```tsx
-// ChartSkeleton.styled.tsx — defines shared animation
-const fadingKeyframes = keyframes`
-  0% { opacity: 0.0625; }
-  50% { opacity: 0.125; }
-  100% { opacity: 0.0625; }
-`;
-export const animationStyles = css`
-  opacity: 0.1;
-  animation: ${fadingKeyframes} 1.5s infinite;
-`;
-
-// AreaSkeleton.styled.tsx — consumes it
-import { animationStyles } from ".../ChartSkeleton.styled";
-export const SkeletonImage = styled.svg`
-  ${animationStyles};
-  flex: 1 1 0;
-  margin-top: 1rem;
-  border-bottom: 1px solid currentColor;
-`;
-
-// BarSkeleton.styled.tsx — also consumes it
-import { animationStyles } from ".../ChartSkeleton.styled";
-export const SkeletonImage = styled.svg`
-  ${animationStyles};
-  flex: 1 1 0;
-  margin-top: 1rem;
-`;
-```
-
-**After — shared CSS module:**
-
-```css
-/* ChartSkeleton.module.css */
-@keyframes fading {
-  0% {
-    opacity: 0.0625;
-  }
-
-  50% {
-    opacity: 0.125;
-  }
-
-  100% {
-    opacity: 0.0625;
-  }
-}
-
-.animated {
-  opacity: 0.1;
-  animation: fading 1.5s infinite;
-}
-```
-
-**After — per-component CSS modules with own styles only:**
-
-```css
-/* AreaSkeleton.module.css */
-.skeletonImage {
-  flex: 1 1 0;
-  margin-top: 1rem;
-  border-bottom: 1px solid currentColor;
-}
-```
-
-```css
-/* BarSkeleton.module.css */
-.skeletonImage {
-  flex: 1 1 0;
-  margin-top: 1rem;
-}
-```
-
-**After — component TSX uses cx() to compose:**
-
-```tsx
-// AreaSkeleton.tsx
-import cx from "classnames";
-import ChartSkeletonS from "../ChartSkeleton/ChartSkeleton.module.css";
-import S from "./AreaSkeleton.module.css";
-
-const AreaSkeleton = (): JSX.Element => {
-  return (
-    <svg
-      className={cx(ChartSkeletonS.animated, S.skeletonImage)}
-      xmlns="http://www.w3.org/2000/svg"
-      viewBox="0 0 371 113"
-      preserveAspectRatio="none"
-    >
-      <path d="..." fill="currentColor" />
-    </svg>
-  );
-};
-```
-
-The shared module owns the `@keyframes` and the `.animated` class. Each consumer composes it with its own module class via `cx()`. No duplication of the keyframe definition.
-
-## Import Template
-
-```tsx
-import cx from "classnames"; // only if needed for conditional classes
-
-import { Box, Flex, Group, Stack, Text, rem } from "metabase/ui";
-
-import S from "./ComponentName.module.css"; // only if CSS module is needed
-```
-
-## Checklist Before Finishing
-
-- [ ] **MANTINE-FIRST CHECK**: Every CSS property that has a style prop equivalent (`c`, `bg`, `p`, `m`, `fw`, `fz`, `flex`, `gap`, `align`, `w`, `h`, etc.) is expressed as a style prop, NOT in a CSS module
-- [ ] `styled.span`/`styled.p` with only color/weight/size are replaced with `Text component="span"` + style props, NOT CSS module classes
-- [ ] `styled.div` with only layout props are replaced with `Flex`/`Stack`/`Group`/`Box` + style props, NOT CSS module classes
-- [ ] Responsive spacing/sizing uses responsive style props (`mb={{ base: "lg", xl: "xl" }}`), NOT CSS module `@media` queries
-- [ ] CSS modules are used ONLY for: pseudo-selectors, box-shadow, border, cursor, overflow, animation, transition, transform, or complex selectors
-- [ ] All `@emotion/styled` and `@emotion/react` imports removed from migrated files
-- [ ] The `.styled.tsx` file is deleted
-- [ ] All imports of the deleted styled file are updated
-- [ ] No static inline styles — `style={{ }}` used only for truly dynamic runtime values
-- [ ] All colors use design tokens (`c="brand"`, `var(--mb-color-brand)`), not raw hex/rgb
-- [ ] All spacing uses design tokens (`p="md"`, `var(--mantine-spacing-md)`), not arbitrary px values — hardcoded `rem`/`px` literals snapped to the nearest token (see mapping table above)
-- [ ] All border-radius values use radius tokens (`var(--mantine-radius-md)`), not hardcoded `0.5rem`
-- [ ] All font sizes use font-size tokens (`fz="md"`, `var(--mantine-font-size-md)`), not hardcoded `1rem`
-- [ ] Layout uses Mantine components (`Flex`, `Stack`, `Group`, `Box`, `Text`) not raw divs/spans with CSS
-- [ ] All CSS module class names use camelCase
-- [ ] No cascading/descendant selectors targeting raw elements — use direct class assignment instead
-- [ ] Component renders identically to the original (visually verify if possible)
-
-## Visual Verification with Screenshots (Optional — Only When Explicitly Asked)
-
-When the user explicitly asks to create before/after screenshots, use the Playwright MCP tools to capture them. This is NOT done by default — only when requested.
-
-Screenshots must be taken in **both light and dark mode** to verify token usage is correct in both themes.
-
-### Switching Color Scheme via API
-
-Toggle between light and dark mode using the Metabase settings API. Use Playwright's `browser_evaluate` or `browser_navigate` with fetch:
-
-```js
-// Switch to dark mode
-await fetch("/api/setting/color-scheme", {
-  method: "PUT",
-  headers: { "Content-Type": "application/json" },
-  body: JSON.stringify({ value: "dark" }),
-});
-
-// Switch to light mode
-await fetch("/api/setting/color-scheme", {
-  method: "PUT",
-  headers: { "Content-Type": "application/json" },
-  body: JSON.stringify({ value: "light" }),
-});
-```
-
-After switching, reload the page for the theme to take effect.
-
-### Process
-
-For each state (**after** = migrated code, **before** = stashed original), capture screenshots in both themes at both viewport widths. This produces **8 screenshots total**.
-
-1. **Take "after" screenshots first** (migrated code is already in place):
-
-   - Navigate to the page that renders the migrated components (`browser_navigate`)
-   - Wait for content to load (`browser_wait_for` with key text, or `textGone: "Loading..."`)
-   - Close the sidebar if it overlaps content on narrow viewports (`browser_click` the toggle button)
-   - **Light mode** (set `color-scheme` to `"light"` via API, reload):

-2. **Stash changes to capture "before" screenshots**:
-
-   - Run `git stash --include-untracked` to temporarily revert to the Emotion version
-   - Repeat the same 4 screenshots with `before-` prefix:
-     - `before-light-desktop.png`, `before-light-narrow.png`
-     - `before-dark-desktop.png`, `before-dark-narrow.png`
-   - Run `git stash pop` to restore the migrated code
-
-3. **Restore the user's original color scheme** (set back to `"auto"` or whatever it was before).
-
-4. **Display all 8 screenshots** using the `Read` tool so the user can visually compare before/after in both themes at both viewport sizes.
-
-### Key Details
-
-- Save screenshots in the repo root (they will be untracked — user can delete after review)
-- The dev server must be running (typically `http://localhost:3000`)
-- Use `browser_snapshot` to find element refs when you need to click buttons (e.g., sidebar toggle)
-- The greeting text on the home page changes randomly on each load — this is expected, not a regression
-- If the page being tested is not the home page, navigate to the correct URL that exercises the migrated components
-- Dark mode screenshots are critical for verifying that CSS variable tokens (`var(--mb-color-*)`) are used correctly — hardcoded colors will look wrong in dark mode

-
-          ## Codespell Output
-          The following spelling errors were detected:

-          PROMPT_HEADER
-          cat codespell_output.txt >> /tmp/claude_prompt.txt

-          ```
-
-          ## Instructions
-          1. **Review the codespell output and identify reported spelling errors** - The usual format codespell uses is `typo ==> correction`
-          2. **Fix every spelling error** - Use the Edit tool to fix each misspelling with the suggested correction
-             - If codespell suggests multiple corrections, choose the most appropriate one based on context
-
-          Human reviewers will verify the changes before merging, so fix all errors reported by codespell.
