• I have filled in the "How did you test this code" section below.

Changes

Adds unique id attributes to buttons across the experiment wizard, metrics page, and warehouse setup so Amplitude autocapture can distinguish elements that share the same text label (e.g. multiple "Continue" and "Create Metric" buttons).

Experiment wizard — step-aware IDs on Continue, Back, Create Experiment, Split evenly, review Edit buttons, and Create Metric buttons in the measurement step.

Metrics page — IDs on Create Metric buttons (empty state vs listing), form submit/cancel, and per-row edit/delete in the metrics table.

Warehouse setup — IDs on Enable, config form save/cancel, connection card edit/delete/test/send-first-event.

Naming convention: {flow}-{context}-{action} (e.g. experiment-wizard-setup-continue, metrics-page-create, warehouse-config-save).

How did you test this code?

Typecheck (npm run typecheck) and lint (eslint --fix) pass with no new errors. Visual inspection of ID uniqueness across all three flows.

📝 Walkthrough

Walkthrough

Adds stable HTML id attributes to experiment metric controls, wizard navigation and review actions, rollout controls, and warehouse settings buttons. The wizard derives button identifiers from step slugs while preserving existing disabled states and handlers. Warehouse connection markup adds identifiers for edit, delete, test, and enable actions without changing the surrounding conditional behaviour.

Estimated code review effort: 2 (Simple) | ~10 minutes
