Phase 3 Plan 04: RemoteConfigStep Summary

Registry-driven backend config form with azureblob/s3/s3-compatible switching, AzureAuthToggle for key/SAS URL, and touch-then-live validation via react-hook-form

Performance

• Duration: 3 min
• Started: 2026-03-27T08:35:50Z
• Completed: 2026-03-27T08:38:45Z
• Tasks: 1 (TDD: 2 commits — test RED then feat GREEN)
• Files modified: 3

Accomplishments

• BACK-01: Azure Blob form — account FieldRenderer + AzureAuthToggle (key + sas_url both always registered, only active one visible)
• BACK-02: S3 form — full BACKEND_REGISTRY loop, provider hidden by FieldRenderer, access_key_id/secret_access_key/region fields
• BACK-03: S3-compatible form — same as S3 plus endpoint field; all 8 tests GREEN

Task Commits

Each task was committed atomically:

1. RED: RemoteConfigStep tests (failing) - a57b2ea (test)
2. GREEN: RemoteConfigStep implementation - 45bcc0c (feat)

TDD tasks have two commits: failing test then passing implementation

Files Created/Modified

• src/components/wizard/RemoteConfigStep.tsx - Step 1 registry-driven backend config form; azureblob special-cased with AzureAuthToggle, S3/S3-compat use full registry loop
• src/components/wizard/RemoteConfigStep.test.tsx - 8 tests covering BACK-01/02/03; uses renderWithBackend helper that dispatches SET_BACKEND_TYPE via useEffect
• package.json + package-lock.json - added @testing-library/user-event for value retention test

Decisions Made

• useEffect guard instead of dispatch-in-render: The original plan template had dispatch({ type: 'SET_STEP', payload: 0 }) directly in the render path (before hooks). Moved to useEffect to prevent React's "cannot update during render" warning and hooks order violation.
• Unconditional fallback schema: useForm must be called unconditionally per hooks rules. When backendType is null, falls back to BACKEND_SCHEMAS['azureblob'] schema, then returns null after all hooks have run.
• toBeDefined() not toBeInTheDocument(): Consistent with existing test files in the project; avoids needing @testing-library/jest-dom matchers setup.

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Installed missing @testing-library/user-event

• Found during: Task 1 RED phase (test file import)
• Issue: Test file imports userEvent from @testing-library/user-event which was not installed
• Fix: Ran npm install --save-dev @testing-library/user-event
• Files modified: package.json, package-lock.json
• Verification: Import resolved, tests ran
• Committed in: a57b2ea (RED test commit)

2. [Rule 1 - Bug] Moved guard dispatch from render to useEffect

• Found during: Task 1 GREEN phase (first test run)
• Issue: Plan template showed dispatch({ type: 'SET_STEP', payload: 0 }) inline in render before useForm hook call, causing React "Cannot update a component while rendering a different component" warning and hooks order violation
• Fix: Guard dispatch moved to useEffect([backendType, dispatch]), fallback schema used to keep useForm unconditional, early return null placed after all hooks
• Files modified: src/components/wizard/RemoteConfigStep.tsx
• Verification: No React warnings, all 8 tests GREEN
• Committed in: 45bcc0c (feat commit)

3. [Rule 1 - Bug] Tests rewritten to use toBeDefined() instead of toBeInTheDocument()

• Found during: Task 1 GREEN phase (test execution)
• Issue: Tests used toBeInTheDocument() which is a @testing-library/jest-dom matcher not configured in this project; project uses toBeDefined() throughout
• Fix: Rewrote all assertions to toBeDefined() and direct value checks (input.value === ...)
• Files modified: src/components/wizard/RemoteConfigStep.test.tsx
• Verification: All 8 tests GREEN without jest-dom matchers
• Committed in: 45bcc0c (feat commit, updated test file)

---

Total deviations: 3 auto-fixed (1 blocking dependency, 2 bugs in plan template code) Impact on plan: All auto-fixes required for correctness. No scope creep.

Issues Encountered

• React hooks rules violation in plan's suggested guard pattern — resolved by moving dispatch to useEffect and using unconditional fallback schema

Next Phase Readiness

• RemoteConfigStep complete and tested; keying on backendType for remount documented
• Plan 05 can integrate RemoteConfigStep into App.tsx with key={state.remote.backendType}
• App.test.tsx and StepIndicator.test.tsx stubs remain RED as expected (wave 0, Plan 05 responsibility)
