+# Phase 19 Plan 03: QuestionForm & Input Components Summary
+
+**OptionGroup (radio/checkbox with "Other" auto-select), FreeTextInput (single/multiline), and QuestionForm (mixed question orchestrator with submit validation)**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-02-04T20:51:07Z
+- **Completed:** 2026-02-04T20:52:15Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- OptionGroup renders radio buttons (single-select) or checkboxes (multi-select) with optional "Other" free-text field that auto-selects when typed into
+- FreeTextInput renders shadcn Input for single-line or shadcn Textarea for multiline based on prop
+- QuestionForm orchestrates sequential questions with mixed input types, tracks answers in local state, and validates all questions answered before enabling submit
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create OptionGroup and FreeTextInput components** - `f73b850` (feat)
+2. **Task 2: Create QuestionForm component** - `648f9db` (feat)
+
+## Files Created/Modified
+- `packages/web/src/components/OptionGroup.tsx` - Radio/checkbox group with "Other" auto-select
+- `packages/web/src/components/FreeTextInput.tsx` - Single-line Input or multiline Textarea wrapper
+- `packages/web/src/components/QuestionForm.tsx` - Multi-question form with answer tracking and submit validation
+
+## Decisions Made
+- OptionGroup value is always a string (comma-joined for multi-select) matching the plan spec for consistent interface
+- QuestionForm owns answer state internally via useState rather than lifting to parent -- keeps component self-contained
+- allowOther defaults to true per plan spec
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- QuestionForm, OptionGroup, and FreeTextInput ready for integration in Plan 19-04 (Inbox Page Assembly)
+- All components type-check and build cleanly
