|
|
|
|
## 2. Frontend Data Layer Refactor ✅ **COMPLETED**
|
|

|
**Status**: ✅ Complete
|
|
|
|
**Completed Items**:
|
|
- ✅ Replaced all mock helpers with real API wrappers in `podcastApi.ts`
|
|
- ✅ Integrated with `aiApiClient` and `pollingApiClient` for backend communication
|
|
- ✅ Implemented job polling helper (`waitForTaskCompletion`) for async research/render jobs
|
|
- ✅ All API calls use real endpoints (createProject, runResearch, generateScript, renderSceneAudio)
|
|
|
|
**Evidence**:
|
|
- `frontend/src/services/podcastApi.ts` - All functions use real API calls

|
## 3. Subscription & Cost Safeguards ⚠️ **PARTIALLY COMPLETED**
|
|
|
|
**Status**: ⚠️ Partial - Preflight checks implemented, but UI blocking needs enhancement
|
|
|
|
**Completed Items**:
|
|
- ✅ Pre-flight validation implemented (`ensurePreflight` function)
|
|
- ✅ Preflight checks before research (`runResearch`) - lines 286-291
|
|
- ✅ Preflight checks before script generation (`generateScript`) - lines 307-312
|
|
- ✅ Preflight checks before render operations (`renderSceneAudio`) - lines 373-378
|
|
- ✅ Preflight checks before preview (`previewLine`) - lines 344-349
|
|
- ✅ Cost estimation function (`estimateCosts`) implemented
|
|
- ✅ Estimate displayed in UI
|
|
|
|
**Missing/Incomplete Items**:
|
|
- ⚠️ UI blocking when preflight fails - errors are thrown but UI doesn't proactively prevent actions
|
|
- ⚠️ Budget cap enforcement - budget cap is set but not enforced before expensive operations
|
|
- ⚠️ Subscription tier-based UI restrictions - HD/multi-speaker modes not hidden for lower tiers
|
|
- ⚠️ Preflight validation UI feedback - users don't see why operations are blocked
|
|
|
|
**Evidence**:
|
|
- `frontend/src/services/podcastApi.ts` lines 210-217, 286-291, 307-312, 344-349, 373-378 show preflight checks
|
|
- `frontend/src/components/PodcastMaker/PodcastDashboard.tsx` shows estimate but no proactive blocking UI
|
|
|
|
**Recommendations**:
|
|
- Add UI blocking before render operations if preflight fails
|
|
- Enforce budget cap before expensive operations
|
|
- Hide premium features based on subscription tier
|
