+# Phase 1 Plan 01: Provider Settings UI Summary
+
+**Tabbed provider settings UI with Replicate/fal.ai API key management and localStorage persistence**
+
+## Performance
+
+- **Duration:** 12 min
+- **Started:** 2026-01-09T12:00:00Z
+- **Completed:** 2026-01-09T12:12:00Z
+- **Tasks:** 3
+- **Files modified:** 3
+
+## Accomplishments
+- Added ProviderType, ProviderConfig, ProviderSettings types for multi-provider support
+- Implemented provider settings state in Zustand store with localStorage persistence
+- Created tabbed UI in ProjectSetupModal with Project and Providers tabs
+- Replicate and fal.ai providers configurable with toggle switches and secure API key inputs
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add provider types to types/index.ts** - `acc6b12` (feat)
+2. **Task 2: Add provider settings state to workflowStore** - `b6b33bb` (feat)
+3. **Task 3: Add Providers tab to ProjectSetupModal** - `0364a8a` (feat)
+
+## Files Created/Modified
+- `src/types/index.ts` - Added ProviderType, ProviderConfig, ProviderSettings types
+- `src/store/workflowStore.ts` - Added providerSettings state, localStorage helpers, and actions (updateProviderSettings, updateProviderApiKey, toggleProvider)
+- `src/components/ProjectSetupModal.tsx` - Added tabbed interface with Providers tab showing Gemini (read-only), Replicate, and fal.ai configuration
+
+## Decisions Made
+- Gemini shows as "Default" with env var info (no user input needed)
+- Replicate and fal.ai disabled by default, require user to enable and enter API key
+- API key inputs use password type with show/hide toggle for security
+- Local state pattern used to avoid saving on every keystroke
+
+## Deviations from Plan
+
+None - plan executed exactly as written
+
+## Issues Encountered
+- Pre-existing lint configuration issue (`next lint` fails due to missing ESLint config). Not related to this plan's changes; build passes successfully.
+
+## Next Phase Readiness
+- Provider types and settings infrastructure ready for Phase 01-02 (Provider abstraction layer)
+- API keys accessible from store for future API route implementations
+- No blockers for continuing to next plan
