Phase 9 Plan 01: MD3 UI Primitives Summary

One-liner: CSS-only floating label TextFieldMD3 component + MD3 button class constants + DEBT-01 aria-label consistency fix across FieldRenderer, PasswordField, and tooltip buttons.

Tasks Completed

Task	Name	Commit	Status
1	Create TextFieldMD3 + MD3 button constants	9441dcd	Complete
2	Fix DEBT-01 aria-label in FieldRenderer + tests	532a994	Complete

Verification

• npx vitest run src/components/ui/TextFieldMD3.test.tsx — 9/9 tests pass
• npx vitest run src/components/ui/FieldRenderer.test.tsx — 4/4 tests pass
• npx vitest run --reporter=dot — 179/179 tests pass (zero regressions)
• src/styles/md3-buttons.ts exports MD3_BTN_FILLED, MD3_BTN_OUTLINED, MD3_BTN_TEXT

Decisions Made

1. Tailwind v4 peer-[:not(:placeholder-shown)] arbitrary variant: Used the bracket syntax form directly — verified it passes through the test suite correctly. No need for the data-has-value JS fallback.

2. placeholder=" " (space) for floating label: TextFieldMD3 always renders with placeholder=" " and placeholder-transparent CSS. This is the CSS-only detection mechanism for the :not(:placeholder-shown) pseudo-class — no React state needed.

3. { selector: 'input' } added to RemoteConfigStep.test.tsx: Once tooltip buttons received aria-label="More info about {field.label}", the getByLabelText(/sas url/i) query matched both the input (via its <label> association) and the tooltip button (via its aria-label). Fixed by scoping the query to { selector: 'input' } in 6 call sites. This is correct behavior — the tests were too broad before.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Test regression from DEBT-01 aria-label fix

• Found during: Task 2, after fixing FieldRenderer.tsx
• Issue: getByLabelText(/sas url/i) in RemoteConfigStep.test.tsx started matching both the PasswordField input (via label association) AND the new tooltip button aria-label="More info about SAS URL", causing "Found multiple elements" errors in 9 tests.
• Fix: Added { selector: 'input' } option to 6 getByLabelText call sites in RemoteConfigStep.test.tsx that queried fields with tooltip buttons. This scopes the accessible name lookup to input elements only.
• Files modified: src/components/wizard/RemoteConfigStep.test.tsx
• Commit: 532a994 (included in Task 2 commit)
