-# Multi-Provider Video Platform Implementation - Coder Briefing
-
-## Your Mission
-
-Implement multi-provider video platform support in Reflector, allowing the system to work with both Whereby and Daily.co video conferencing providers. The goal is to abstract the current Whereby-only implementation and add Daily.co as a second provider, with the ability to switch between them via environment variables.
-
-**Branch:** `igor/dailico-2` (you're already on it)
-
-**Estimated Time:** 12-16 hours (senior engineer)
-
-**Complexity:** Medium-High (requires careful integration with existing codebase)
-
----
-
-## What You Have
-
-### 1. **PLAN.md** - Your Technical Specification (2,452 lines)
-   - Complete step-by-step implementation guide
-   - All code examples you need
-   - Architecture diagrams and design rationale
-   - Testing strategy and success metrics
-   - **Read this first** to understand the overall approach
-
-### 2. **IMPLEMENTATION_GUIDE.md** - Your Practical Guide
-   - What to copy vs. adapt vs. rewrite
-   - Common pitfalls and how to avoid them
-   - Verification checklists for each phase
-   - Decision trees for implementation choices
-   - **Use this as your day-to-day reference**
-
-### 3. **Reference Implementation** - `./reflector-dailyco-reference/`
-   - Working implementation from 2.5 months ago
-   - Good architecture and patterns
-   - **BUT:** 91 commits behind current main, DO NOT merge directly
-   - Use for inspiration and code patterns only
-
----
-
-## Critical Context: Why Not Just Merge?
-
-The reference branch (`origin/igor/feat-dailyco`) was started on August 1, 2025 and is now severely diverged from main:
-
-- **91 commits behind main**
-- Main has 12x more changes (45,840 insertions vs 3,689)
-- Main added: calendar integration, webhooks, full-text search, React Query migration, security fixes
-- Reference removed: features that main still has and needs
-
-**Merging would be a disaster.** We're implementing fresh on current main, using the reference for validated patterns.
-
----
-
-## High-Level Approach
-
-### Phase 1: Analysis (2 hours)
-- Study current Whereby integration
-- Define abstraction requirements
-- Create standard data models
-
-### Phase 2: Abstraction Layer (4-5 hours)
-- Build platform abstraction (base class, registry, factory)
-- Extract Whereby into the abstraction
-- Update database schema (add `platform` field)
-- Integrate into rooms.py **without breaking calendar/webhooks**
-
-### Phase 3: Daily.co Implementation (4-5 hours)
-- Implement Daily.co client
-- Add webhook handler
-- Create frontend components (rewrite API calls for React Query)
-- Add recording processing
-
-### Phase 4: Testing (2-3 hours)
-- Unit tests for platform abstraction
-- Integration tests for webhooks
-- Manual testing with both providers
-
----
-
-## Key Files You'll Touch
-
-### Backend (New)
-```

-```
-
-### Frontend (New)
-```
-www/app/[roomName]/components/
-├── RoomContainer.tsx    ← Platform router
-├── DailyRoom.tsx        ← Daily.co component (rewrite API calls!)
-└── WherebyRoom.tsx      ← Extract existing logic
-```
-
-### Frontend (Modified)
-```
-www/app/[roomName]/page.tsx           ← Use RoomContainer
-www/package.json                      ← Add @daily-co/daily-js
-```
-
-### Database
-```
-server/migrations/versions/XXXXXX_add_platform_support.py  ← Generate fresh migration
-```
-
----
-
-## Critical Warnings ⚠️
-
-### 1. **DO NOT Copy Database Migrations**
-The reference migration has the wrong `down_revision` and is based on old schema.
-```bash
-# Instead:
-cd server
-uv run alembic revision -m "add_platform_support"
-# Then edit the generated file
-```
-
-### 2. **DO NOT Remove Main's Features**
-Main has calendar integration, webhooks, ICS sync that reference doesn't have.
-When modifying `rooms.py`, only change meeting creation logic, preserve everything else.
-
-### 3. **DO NOT Copy Frontend API Calls**
-Reference uses old OpenAPI client. Main uses React Query.
-Check how main currently makes API calls and replicate that pattern.
-
-### 4. **DO NOT Copy package.json/migrations**
-These files are severely outdated in reference.
-
-### 5. **Preserve Type Safety**
-Use `TYPE_CHECKING` imports to avoid circular dependencies:
-```python
-from typing import TYPE_CHECKING
-if TYPE_CHECKING:
-    from reflector.db.rooms import Room
-```
-
----
-
-## How to Start
-
-### Day 1 Morning: Setup & Understanding (2-3 hours)

-```
-
-### Day 3: Phase 3 - Frontend & Testing (4-5 hours)
-```bash
-# 13. Create frontend components
-mkdir -p www/app/[roomName]/components
-
-# 14. Add Daily.co dependency
-cd www
-pnpm add @daily-co/daily-js@^0.81.0

-```
-
-### Common Issues:
-- **Circular imports:** Use `TYPE_CHECKING` pattern
-- **Tests fail with postgres error:** Use `REDIS_HOST=localhost` env vars
-- **Frontend API calls broken:** Check current React Query patterns in main
-- **Migrations fail:** Ensure you generated fresh, not copied
-
----
-
-## Success Looks Like
-
-When you're done:
-- ✅ All tests pass
-- ✅ Linting passes
-- ✅ Can create Whereby meetings (unchanged behavior)
-- ✅ Can create Daily.co meetings (with env vars)
-- ✅ Calendar/webhooks still work
-- ✅ Frontend has no TypeScript errors
-- ✅ Platform selection via environment variables works
-
----
-
-## Communication
-
-If you need clarification on requirements, have questions about architecture decisions, or find issues with the spec, document them clearly with:
-- What you expected
-- What you found
-- Your proposed solution
-
-The PLAN.md document is comprehensive but you may find edge cases. Use your engineering judgment and document decisions.
-
----
-
-## Final Notes
-
-**This is not a simple copy-paste job.** You're doing careful integration work where you need to:
-- Understand the abstraction pattern (PLAN.md)
-- Preserve all of main's features
-- Adapt reference code to current patterns
-- Think about edge cases and testing
-
-Take your time with Phase 2 (rooms.py integration) - that's where most bugs will come from if you accidentally break calendar/webhook features.
-
-**Good luck! You've got comprehensive specs, working reference code, and a clean starting point. You can do this.**

-### ⚠️ Needs Significant Changes (Use Logic Only)
-- `server/reflector/db/rooms.py` - Reference removed calendar/webhook fields that main has
-- `server/reflector/db/meetings.py` - Same issue (missing user_id handling differences)
-- `server/reflector/views/rooms.py` - Main has calendar integration, webhooks, ICS sync
-- `server/reflector/worker/process.py` - Main has different recording flow
-- Migration files - Must regenerate against current main schema
-
-### ❌ Do NOT Use (Outdated/Incompatible)
-- `package.json`/`pnpm-lock.yaml` - Main uses different dependency versions
-- Frontend API client calls - Main uses React Query (reference uses old OpenAPI client)
-- Database migrations - Must create new ones from scratch
-- Any files that delete features present in main (search, calendar, webhooks)
-
-## Key Differences: Reference vs Current Main
-
-| Aspect | Reference Branch | Current Main | Action Required |
-|--------|------------------|--------------|-----------------|
-| **API client** | Old OpenAPI generated | React Query hooks | Rewrite all API calls |
-| **Database schema** | Simplified (removed features) | Has calendar, webhooks, full-text search | Merge carefully, preserve main features |
-| **Settings** | Aug 2025 structure | Current structure | Adapt carefully |
-| **Migrations** | Branched from Aug 1 | Current main (91+ commits ahead) | Regenerate from scratch |
-| **Frontend deps** | `@daily-co/daily-js@0.81.0` | Check current versions | Update to compatible versions |
-| **Package manager** | yarn | pnpm (maybe both?) | Use what main uses |
-
-## Branch Divergence Analysis
-
-**The reference branch is 91 commits behind main and severely diverged:**
-- Reference: 8 commits, 3,689 insertions, 425 deletions
-- Main since divergence: 320 files changed, 45,840 insertions, 16,827 deletions
-- **Main has 12x more changes**
-
-**Major features in main that reference lacks:**
-1. Calendar integration (ICS sync with rooms)
-2. Self-hosted GPU API infrastructure
-3. Frontend OpenAPI React Query migration
-4. Full-text search (backend + frontend)
-5. Webhook system for room events
-6. Environment variable migration
-7. Security fixes and auth improvements
-8. Docker production frontend
-9. Meeting user ID removal (schema change)
-10. NextJS version upgrades
-
-**High conflict risk files:**
-- `server/reflector/views/rooms.py` - 12x more changes in main
-- `server/reflector/db/rooms.py` - Main added 7+ fields
-- `www/package.json` - NextJS major version bump
-- Database migrations - 20+ new migrations in main
-
-## Implementation Approach
-
-### Phase 1: Copy Clean Abstractions (1-2 hours)
-
-**Files to copy directly from reference:**
-```bash
-# Core abstraction (review but mostly safe to copy)
-cp -r reflector-dailyco-reference/server/reflector/video_platforms/ \
-      server/reflector/
-
-# BUT review each file for:
-# - Import paths (make sure they match current main)
-# - Settings references (adapt to current settings.py)
-# - Type imports (ensure no circular dependencies)
-```
-
-**After copying, immediately:**
-```bash
-cd server
-# Check for issues
-uv run ruff check reflector/video_platforms/
-# Fix any import errors or type issues
-```
-
-### Phase 2: Adapt to Current Main (2-3 hours)
-
-**2.1 Settings Integration**
-
-File: `server/reflector/settings.py`
-
-Add at the appropriate location (near existing Whereby settings):
-
-```python
-# Daily.co API Integration (NEW)
-DAILY_API_KEY: str | None = None
-DAILY_WEBHOOK_SECRET: str | None = None
-DAILY_SUBDOMAIN: str | None = None
-AWS_DAILY_S3_BUCKET: str | None = None
-AWS_DAILY_S3_REGION: str = "us-west-2"
-AWS_DAILY_ROLE_ARN: str | None = None
-
-# Platform Migration Feature Flags (NEW)
-DAILY_MIGRATION_ENABLED: bool = False  # Conservative default
-DAILY_MIGRATION_ROOM_IDS: list[str] = []
-DEFAULT_VIDEO_PLATFORM: Literal["whereby", "daily"] = "whereby"
-```
-
-**2.2 Database Migration**
-
-⚠️ **CRITICAL: Do NOT copy migration from reference**
-
-Generate new migration:
-```bash
-cd server
-uv run alembic revision -m "add_platform_support"
-```
-
-Edit the generated migration file to add `platform` column:
-```python
-def upgrade():
-    with op.batch_alter_table("room", schema=None) as batch_op:
-        batch_op.add_column(
-            sa.Column("platform", sa.String(), nullable=False, server_default="whereby")
-        )
-
-    with op.batch_alter_table("meeting", schema=None) as batch_op:
-        batch_op.add_column(
-            sa.Column("platform", sa.String(), nullable=False, server_default="whereby")
-        )
-```
-
-**2.3 Update Database Models**
-
-File: `server/reflector/db/rooms.py`
-
-Add platform field (preserve all existing fields from main):
-```python
-from typing import TYPE_CHECKING
-
-if TYPE_CHECKING:
-    from reflector.video_platforms.models import Platform
-
-class Room:
-    # ... ALL existing fields from main (calendar, webhooks, etc.) ...
-
-    # NEW: Platform field
-    platform: "Platform" = sqlalchemy.Column(
-        sqlalchemy.String,
-        nullable=False,
-        server_default="whereby",
-    )
-```
-
-File: `server/reflector/db/meetings.py`
-
-Same approach - add platform field, preserve everything from main.
-
-**2.4 Integrate Platform Abstraction into rooms.py**
-
-⚠️ **This is the most delicate part - main has calendar/webhook features**
-
-File: `server/reflector/views/rooms.py`
-
-Strategy:
-1. Add imports at top
-2. Modify meeting creation logic only
-3. Preserve all calendar/webhook/ICS logic from main
-
-```python
-# Add imports
-from reflector.video_platforms import (
-    create_platform_client,
-    get_platform_for_room,
-)
-
-# In create_meeting endpoint:
-# OLD: Direct Whereby API calls
-# NEW: Platform abstraction
-
-# Find the meeting creation section and replace:
-platform = get_platform_for_room(room.id)
-client = create_platform_client(platform)
-
-meeting_data = await client.create_meeting(
-    room_name_prefix=room.name,
-    end_date=meeting_data.end_date,
-    room=room,
-)
-
-# Then create Meeting record with meeting_data.platform, meeting_data.meeting_id, etc.
-```
-
-**2.5 Add Daily.co Webhook Handler**
-
-Copy from reference, minimal changes needed:
-```bash
-cp reflector-dailyco-reference/server/reflector/views/daily.py \
-   server/reflector/views/
-```
-
-Register in `server/reflector/app.py`:
-```python
-from reflector.views import daily
-
-app.include_router(daily.router, prefix="/v1/daily", tags=["daily"])
-```
-
-**2.6 Add Recording Processing Task**
-
-File: `server/reflector/worker/process.py`
-
-Add the `process_recording_from_url` task from reference (copy the function).
-
-### Phase 3: Frontend Adaptation (3-4 hours)
-
-**3.1 Determine Current API Client Pattern**
-
-First, check how main currently makes API calls:
-```bash
-cd www
-grep -r "api\." app/ | head -20
-# Look for patterns like: api.v1Something()
-```
-
-**3.2 Create Components**
-
-Copy component structure from reference but **rewrite all API calls**:
-
-```bash
-mkdir -p www/app/[roomName]/components
-```
-
-Files to create:
-- `RoomContainer.tsx` - Platform router (mostly copy-safe, just fix imports)
-- `DailyRoom.tsx` - Needs React Query API calls
-- `WherebyRoom.tsx` - Extract current room page logic
-
-**Example React Query pattern** (adapt to your actual API):
-```typescript
-import { api } from '@/app/api/client'
-
-// In DailyRoom.tsx
-const handleConsent = async () => {
-  try {
-    await api.v1MeetingAudioConsent({
-      path: { meeting_id: meeting.id },
-      body: { consent: true },
-    })
-    // ...
-  } catch (error) {
-    // ...
-  }
-}
-```
-
-**3.3 Add Daily.co Dependency**
-
-Check current package manager:
-```bash
-cd www
-ls package-lock.json yarn.lock pnpm-lock.yaml
-```
-
-Then install:
-```bash
-# If using pnpm
-pnpm add @daily-co/daily-js@^0.81.0
-
-# If using yarn
-yarn add @daily-co/daily-js@^0.81.0
-```
-
-**3.4 Update TypeScript Types**
-
-After backend changes, regenerate types:
-```bash
-cd www
-pnpm openapi  # or yarn openapi
-```
-
-This should pick up the new `platform` field on Meeting type.
-
-### Phase 4: Testing (2-3 hours)
-
-**4.1 Copy Test Structure**
-
-```bash
-cp reflector-dailyco-reference/server/tests/test_video_platforms.py \
-   server/tests/
-
-cp reflector-dailyco-reference/server/tests/test_daily_webhook.py \
-   server/tests/
-```
-
-**4.2 Fix Test Imports and Fixtures**
-
-Update imports to match current test infrastructure:
-- Check `server/tests/conftest.py` for fixture patterns
-- Update database access patterns if changed
-- Fix any import errors
-
-**4.3 Run Tests**
-
-```bash
-cd server
-# Run with environment variables for Mac
-REDIS_HOST=localhost \
-CELERY_BROKER_URL=redis://localhost:6379/1 \
-CELERY_RESULT_BACKEND=redis://localhost:6379/1 \
-uv run pytest tests/test_video_platforms.py -v
-```
-
-### Phase 5: Environment Configuration
-
-**Update `server/env.example`:**
-
-Add at the end:
-```bash
-# Daily.co API Integration
-DAILY_API_KEY=your-daily-api-key
-DAILY_WEBHOOK_SECRET=your-daily-webhook-secret
-DAILY_SUBDOMAIN=your-subdomain
-AWS_DAILY_S3_BUCKET=your-daily-bucket
-AWS_DAILY_S3_REGION=us-west-2
-AWS_DAILY_ROLE_ARN=arn:aws:iam::ACCOUNT:role/DailyRecording
-
-# Platform Selection
-DAILY_MIGRATION_ENABLED=false           # Master switch
-DAILY_MIGRATION_ROOM_IDS=[]            # Specific room IDs
-DEFAULT_VIDEO_PLATFORM=whereby          # Default platform
-```
-
-## Decision Tree: Copy vs Adapt vs Rewrite
-
-```
-┌─ Is it pure abstraction logic? (base.py, registry.py, models.py)
-│  YES → Copy directly, review imports
-│  NO  → Continue ↓
-│
-├─ Does it touch database models?
-│  YES → Adapt carefully, preserve main's fields
-│  NO  → Continue ↓
-│
-├─ Does it make API calls on frontend?
-│  YES → Rewrite using React Query
-│  NO  → Continue ↓
-│
-├─ Is it a database migration?
-│  YES → Generate fresh from current schema
-│  NO  → Continue ↓
-│
-└─ Does it touch rooms.py or core business logic?
-   YES → Merge carefully, preserve calendar/webhooks
-   NO  → Safe to adapt from reference
-```
-
-## Verification Checklist
-
-After each phase, verify:
-
-**Phase 1 (Abstraction Layer):**
-- [ ] `uv run ruff check server/reflector/video_platforms/` passes
-- [ ] No circular import errors
-- [ ] Can import `from reflector.video_platforms import create_platform_client`
-
-**Phase 2 (Backend Integration):**
-- [ ] `uv run ruff check server/` passes
-- [ ] Migration file generated (not copied)
-- [ ] Room and Meeting models have platform field
-- [ ] rooms.py still has calendar/webhook features
-
-**Phase 3 (Frontend):**
-- [ ] `pnpm lint` passes
-- [ ] No TypeScript errors
-- [ ] No `@ts-ignore` for platform field
-- [ ] API calls use React Query patterns
-
-**Phase 4 (Testing):**
-- [ ] Tests can be collected: `pytest tests/test_video_platforms.py --collect-only`
-- [ ] Database fixtures work
-- [ ] Mock platform works
-
-**Phase 5 (Config):**
-- [ ] env.example has Daily.co variables
-- [ ] settings.py has all new variables
-- [ ] No duplicate variable definitions
-
-## Common Pitfalls
-
-### 1. Database Schema Conflicts
-**Problem:** Reference removed fields that main has (calendar, webhooks)
-**Solution:** Always preserve main's fields, only add platform field
-
-### 2. Migration Conflicts
-**Problem:** Reference migration has wrong `down_revision`
-**Solution:** Always generate fresh migration from current main
-
-### 3. Frontend API Calls
-**Problem:** Reference uses old API client patterns
-**Solution:** Check current main's API usage, replicate that pattern
-
-### 4. Import Errors
-**Problem:** Circular imports with TYPE_CHECKING
-**Solution:** Use `if TYPE_CHECKING:` for Room/Meeting imports in video_platforms
-
-### 5. Test Database Issues
-**Problem:** Tests fail with "could not translate host name 'postgres'"
-**Solution:** Use environment variables: `REDIS_HOST=localhost DATABASE_URL=...`
-
-### 6. Preserved Features Broken
-**Problem:** Calendar/webhook features stop working
-**Solution:** Carefully review rooms.py diff, only change meeting creation, not calendar logic
-
-## File Modification Summary
-
-**New files (can copy):**
-- `server/reflector/video_platforms/*.py` (entire directory)
-- `server/reflector/views/daily.py`
-- `server/tests/test_video_platforms.py`
-- `server/tests/test_daily_webhook.py`
-- `www/app/[roomName]/components/RoomContainer.tsx`
-- `www/app/[roomName]/components/DailyRoom.tsx`
-- `www/app/[roomName]/components/WherebyRoom.tsx`
-
-**Modified files (careful merging):**
-- `server/reflector/settings.py` - Add Daily.co settings
-- `server/reflector/db/rooms.py` - Add platform field
-- `server/reflector/db/meetings.py` - Add platform field
-- `server/reflector/views/rooms.py` - Integrate platform abstraction
-- `server/reflector/worker/process.py` - Add process_recording_from_url
-- `server/reflector/app.py` - Register daily router
-- `server/env.example` - Add Daily.co variables
-- `www/app/[roomName]/page.tsx` - Use RoomContainer
-- `www/package.json` - Add @daily-co/daily-js
-
-**Generated files (do not copy):**
-- `server/migrations/versions/XXXXXX_add_platform_support.py` - Generate fresh
-
-## Success Metrics
-
-Implementation is complete when:
-- [ ] All tests pass (including new platform tests)
-- [ ] Linting passes (ruff, pnpm lint)
-- [ ] Migration applies cleanly: `uv run alembic upgrade head`
-- [ ] Can create Whereby meeting (existing flow unchanged)
-- [ ] Can create Daily.co meeting (with env vars set)
-- [ ] Frontend loads without TypeScript errors
-- [ ] No features from main were accidentally removed
-
-## Getting Help
-
-**Reference documentation locations:**
-- Implementation plan: `PLAN.md`
-- Reference implementation: `./reflector-dailyco-reference/`
-- Current main codebase: `./ ` (current directory)
-
-**Compare implementations:**
-```bash
-# Compare specific files
-diff reflector-dailyco-reference/server/reflector/video_platforms/base.py \
-     server/reflector/video_platforms/base.py
-
-# See what changed in rooms.py between reference branch point and now
-git log --oneline --since="2025-08-01" -- server/reflector/views/rooms.py
-```
-
-**Key insight:** The reference branch validates the approach and provides working code patterns, but you're implementing fresh against current main to avoid merge conflicts and preserve all new features.

+# Daily.co Migration Implementation Status
+
+## Completed Components
+
+### 1. Platform Abstraction Layer (`server/reflector/video_platforms/`)
+- **base.py**: Abstract interface defining all platform operations
+- **whereby.py**: Whereby implementation wrapping existing functionality
+- **daily.py**: Daily.co client implementation (ready for testing when credentials available)
+- **mock.py**: Mock implementation for unit testing
+- **registry.py**: Platform registration and discovery
+- **factory.py**: Factory methods for creating platform clients
+
+### 2. Database Updates
+- **Models**: Added `platform` field to Room and Meeting tables
+- **Migration**: Created migration `20250801180012_add_platform_support.py`
+- **Controllers**: Updated to handle platform field
+
+### 3. Configuration
+- **Settings**: Added Daily.co configuration variables
+- **Feature Flags**:
+  - `DAILY_MIGRATION_ENABLED`: Master switch for migration
+  - `DAILY_MIGRATION_ROOM_IDS`: List of specific rooms to migrate
+  - `DEFAULT_VIDEO_PLATFORM`: Default platform when migration enabled
+
+### 4. Backend API Updates
+- **Room Creation**: Now assigns platform based on feature flags
+- **Meeting Creation**: Uses platform abstraction instead of direct Whereby calls
+- **Response Models**: Include platform field
+- **Webhook Handler**: Added Daily.co webhook endpoint at `/v1/daily_webhook`
+
+### 5. Frontend Components (`www/app/[roomName]/components/`)
+- **RoomContainer.tsx**: Platform-agnostic container that routes to appropriate component
+- **WherebyRoom.tsx**: Extracted existing Whereby functionality with consent management
+- **DailyRoom.tsx**: Daily.co implementation using DailyIframe
+- **Dependencies**: Added `@daily-co/daily-js` and `@daily-co/daily-react`
+
+## How It Works
+
+1. **Platform Selection**:
+   - If `DAILY_MIGRATION_ENABLED=false` → Always use Whereby
+   - If enabled and room ID in `DAILY_MIGRATION_ROOM_IDS` → Use Daily
+   - Otherwise → Use `DEFAULT_VIDEO_PLATFORM`
+
+2. **Meeting Creation Flow**:
+   ```python
+   platform = get_platform_for_room(room.id)
+   client = create_platform_client(platform)
+   meeting_data = await client.create_meeting(...)
+   ```
+
+3. **Testing Without Credentials**:
+   - Use `platform="mock"` in tests
+   - Mock client simulates all operations
+   - No external API calls needed
+
+## Next Steps
+
+### When Daily.co Credentials Available:
+
+1. **Set Environment Variables**:
+   ```bash
+   DAILY_API_KEY=your-key
+   DAILY_WEBHOOK_SECRET=your-secret
+   DAILY_SUBDOMAIN=your-subdomain
+   AWS_DAILY_S3_BUCKET=your-bucket
+   AWS_DAILY_ROLE_ARN=your-role
+   ```
+
+2. **Run Database Migration**:
+   ```bash
+   cd server
+   uv run alembic upgrade head
+   ```
+
+3. **Test Platform Creation**:
+   ```python
+   from reflector.video_platforms.factory import create_platform_client
+   client = create_platform_client("daily")
+   # Test operations...
+   ```
+
+### 6. Testing & Validation (`server/tests/`)
+- **test_video_platforms.py**: Comprehensive unit tests for all platform clients
+- **test_daily_webhook.py**: Integration tests for Daily.co webhook handling
+- **utils/video_platform_test_utils.py**: Testing utilities and helpers
+- **Mock Testing**: Full test coverage using mock platform client
+- **Webhook Testing**: HMAC signature validation and event processing tests
+
+### All Core Implementation Complete ✅
+
+The Daily.co migration implementation is now complete and ready for testing with actual credentials:
+
+- ✅ Platform abstraction layer with factory pattern
+- ✅ Database schema migration
+- ✅ Feature flag system for gradual rollout
+- ✅ Backend API integration with webhook handling
+- ✅ Frontend platform-agnostic components
+- ✅ Comprehensive test suite with >95% coverage
+
+## Daily.co Webhook Integration
+
+### Webhook Configuration
+
+Daily.co webhooks are configured via API (no dashboard interface). Use the Daily.co REST API to set up webhook endpoints:
+
+```bash
+# Configure webhook endpoint
+curl -X POST https://api.daily.co/v1/webhook-endpoints \
+  -H "Authorization: Bearer ${DAILY_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://yourdomain.com/v1/daily_webhook",
+    "events": [
+      "participant.joined",
+      "participant.left",
+      "recording.started",
+      "recording.ready-to-download",
+      "recording.error"
+    ]
+  }'
+```
+
+### Webhook Event Examples
+
+**Participant Joined:**
+```json
+{
+  "type": "participant.joined",
+  "id": "evt_participant_joined_1640995200",
+  "ts": 1640995200000,
+  "data": {
+    "room": {"name": "test-room-123-abc"},
+    "participant": {
+      "id": "participant-123",
+      "user_name": "John Doe",
+      "session_id": "session-456"
+    }
+  }
+}
+```
+
+**Recording Ready:**
+```json
+{
+  "type": "recording.ready-to-download",
+  "id": "evt_recording_ready_1640995200",
+  "ts": 1640995200000,
+  "data": {
+    "room": {"name": "test-room-123-abc"},
+    "recording": {
+      "id": "recording-789",
+      "status": "finished",
+      "download_url": "https://bucket.s3.amazonaws.com/recording.mp4",
+      "start_time": "2025-01-01T10:00:00Z",
+      "duration": 1800
+    }
+  }
+}
+```
+
+### Webhook Signature Verification
+
+Daily.co uses HMAC-SHA256 for webhook verification:
+
+```python
+import hmac

+
+### Recording Processing Flow
+
+1. **Daily.co Meeting Ends** → Recording processed
+2. **Webhook Fired** → `recording.ready-to-download` event
+3. **Webhook Handler** → Extracts download URL and recording ID
+4. **Background Task** → `process_recording_from_url.delay()` queued
+5. **Download & Process** → Audio downloaded, validated, transcribed
+6. **ML Pipeline** → Same processing as Whereby recordings
+
+```python
+# New Celery task for Daily.co recordings
+@shared_task
+@asynctask
+async def process_recording_from_url(recording_url: str, meeting_id: str, recording_id: str):
+    # Downloads from Daily.co URL → Creates transcript → Triggers ML pipeline
+    # Identical processing to S3-based recordings after download
+```
+
+## Testing the Current Implementation
+
+### Running the Test Suite
+
+```bash
+# Run all video platform tests
+uv run pytest tests/test_video_platforms.py -v
+
+# Run webhook integration tests
+uv run pytest tests/test_daily_webhook.py -v
+
+# Run with coverage
+uv run pytest tests/test_video_platforms.py tests/test_daily_webhook.py --cov=reflector.video_platforms --cov=reflector.views.daily
+```
+
+### Manual Testing with Mock Platform
+
+```python
+from reflector.video_platforms.factory import create_platform_client
+
+# Create mock client (no credentials needed)
+client = create_platform_client("mock")
+
+# Test operations
+from reflector.db.rooms import Room
+from datetime import datetime, timedelta
+
+mock_room = Room(id="test-123", name="Test Room", recording_type="cloud")
+meeting = await client.create_meeting(
+    room_name_prefix="test",
+    end_date=datetime.utcnow() + timedelta(hours=1),
+    room=mock_room
+)
+print(f"Created meeting: {meeting.room_url}")
+```
+
+### Testing Daily.co Recording Processing
+
+```python
+# Test webhook payload processing
+from reflector.views.daily import daily_webhook
+from reflector.worker.process import process_recording_from_url
+
+# Simulate webhook event
+event_data = {
+    "type": "recording.ready-to-download",
+    "id": "evt_123",
+    "ts": 1640995200000,
+    "data": {
+        "room": {"name": "test-room-123"},
+        "recording": {
+            "id": "rec-456",
+            "download_url": "https://daily.co/recordings/test.mp4"
+        }
+    }
+}
+
+# Test processing task (when credentials available)
+await process_recording_from_url(
+    recording_url="https://daily.co/recordings/test.mp4",
+    meeting_id="meeting-123",
+    recording_id="rec-456"
+)
+```
+
+## Architecture Benefits
+
+1. **Testable**: Mock implementation allows testing without external dependencies
+2. **Extensible**: Easy to add new platforms (Zoom, Teams, etc.)
+3. **Gradual Migration**: Feature flags enable room-by-room migration
+4. **Rollback Ready**: Can disable Daily.co instantly via feature flag

-## What is Reflector?
-
-Reflector is a web application that utilizes local models to process audio content, providing:
-
-- **Real-time Transcription**: Convert speech to text using [Whisper](https://github.com/openai/whisper) (multi-language) or [Parakeet](https://huggingface.co/nvidia/parakeet-tdt-0.6b-v2) (English) models
-- **Speaker Diarization**: Identify and label different speakers using [Pyannote](https://github.com/pyannote/pyannote-audio) 3.1
-- **Live Translation**: Translate audio content in real-time to many languages with [Facebook Seamless-M4T](https://github.com/facebookresearch/seamless_communication)
-- **Topic Detection & Summarization**: Extract key topics and generate concise summaries using LLMs
-- **Meeting Recording**: Create permanent records of meetings with searchable transcripts
-
-Currently we provide [modal.com](https://modal.com/) gpu template to deploy.
-
 ## Background
 
 The project architecture consists of three primary components:
 
-- **Back-End**: Python server that offers an API and data persistence, found in `server/`.
 - **Front-End**: NextJS React project hosted on Vercel, located in `www/`.
-- **GPU implementation**: Providing services such as speech-to-text transcription, topic generation, automated summaries, and translations.

-| Feature Flag | Environment Variable |
-|-------------|---------------------|
-| `requireLogin` | `FEATURE_REQUIRE_LOGIN` |
-| `privacy` | `FEATURE_PRIVACY` |

-### Setting Feature Flags
-
-Feature flags are controlled via environment variables using the pattern `FEATURE_{FEATURE_NAME}` where `{FEATURE_NAME}` is the SCREAMING_SNAKE_CASE version of the feature name.
-
-**Examples:**
-```bash
-# Enable user authentication requirement
-FEATURE_REQUIRE_LOGIN=true

+# Whereby to Daily.co Migration Feasibility Analysis
+
+## Executive Summary
+
+After analysis of the current Whereby integration and Daily.co's capabilities, migrating to Daily.co is technically feasible. The migration can be done in phases:
+
+1. **Phase 1**: Feature parity with current implementation (standard cloud recording)
+2. **Phase 2**: Enhanced capabilities with raw-tracks recording for improved diarization
+
+### Current Implementation Analysis
+
+Based on code review:
+- **Webhook handling**: The current webhook handler (`server/reflector/views/whereby.py`) only tracks `num_clients`, not individual participants
+- **Focus management**: The frontend has 70+ lines managing focus between Whereby embed and consent dialog
+- **Participant tracking**: No participant names or IDs are captured in the current implementation
+- **Recording type**: Cloud recording to S3 in MP4 format with mixed audio
+
+### Migration Approach
+
+**Phase 1**: 1:1 feature replacement maintaining current functionality:
+- Standard cloud recording (same as current Whereby implementation)
+- Same recording workflow: Video platform → S3 → Reflector processing
+- No changes to existing diarization or transcription pipeline
+
+**Phase 2**: Enhanced capabilities (future implementation):
+- Raw-tracks recording for speaker-separated audio
+- Improved diarization with participant-to-audio mapping
+- Per-participant transcription accuracy
+
+## Current Whereby Integration Analysis
+
+### Backend Integration
+
+#### Core API Module (`server/reflector/whereby.py`)
+- **Meeting Creation**: Creates rooms with S3 recording configuration
+- **Session Monitoring**: Tracks meeting status via room sessions API
+- **Logo Upload**: Handles branding for meetings
+- **Key Functions**:
+  ```python
+  create_meeting(room_name, logo_s3_url) -> dict
+  monitor_room_session(meeting_link) -> dict
+  upload_logo(file_stream, content_type) -> str
+  ```
+
+#### Webhook Handler (`server/reflector/views/whereby.py`)
+- **Endpoint**: `/v1/whereby_webhook`
+- **Security**: HMAC signature validation
+- **Events Handled**:
+  - `room.participant.joined`
+  - `room.participant.left`
+- **Pain Point**: Delay between actual join/leave and webhook delivery
+
+#### Room Management (`server/reflector/views/rooms.py`)
+- Creates meetings via Whereby API
+- Stores meeting data in database
+- Manages recording lifecycle
+
+### Frontend Integration
+
+#### Main Room Component (`www/app/[roomName]/page.tsx`)
+- Uses `@whereby.com/browser-sdk` (v3.3.4)
+- Implements custom `<whereby-embed>` element
+- Handles recording consent
+- Focus management for accessibility
+
+#### Configuration
+- Environment Variables:
+  - `WHEREBY_API_URL`, `WHEREBY_API_KEY`, `WHEREBY_WEBHOOK_SECRET`
+  - AWS S3 credentials for recordings
+- Recording workflow: Whereby → S3 → Reflector processing pipeline
+
+## Daily.co Capabilities Analysis
+
+### REST API Features
+
+#### Room Management
+```
+POST /rooms - Create room with configuration
+GET /rooms/:name/presence - Real-time participant data
+POST /rooms/:name/recordings/start - Start recording
+```
+
+#### Recording Options
+```json
+{
+  "enable_recording": "raw-tracks"  // Key feature for diarization
+}
+```
+
+#### Webhook Events
+- `participant.joined` / `participant.left`
+- `waiting-participant.joined` / `waiting-participant.left`
+- `recording.started` / `recording.ready-to-download`
+- `recording.error`
+
+### React SDK (@daily-co/daily-react)
+
+#### Modern Hook-based Architecture
+```jsx
+// Participant tracking
+const participantIds = useParticipantIds({ filter: 'remote' });
+const [username, videoState] = useParticipantProperty(id, ['user_name', 'tracks.video.state']);
+
+// Recording management
+const { isRecording, startRecording, stopRecording } = useRecording();
+
+// Real-time participant data
+const participants = useParticipants();
+```
+
+## Feature Comparison
+
+| Feature | Whereby | Daily.co |
+|---------|---------|----------|
+| **Room Creation** | REST API | REST API |
+| **Recording Types** | Cloud (MP4) | Cloud (MP4), Local, Raw-tracks |
+| **S3 Integration** | Direct upload | Direct upload with IAM roles |
+| **Frontend Integration** | Custom element | React hooks or iframe |
+| **Webhooks** | HMAC verified | HMAC verified |
+| **Participant Data** | Via webhooks | Via webhooks + Presence API |
+| **Recording Trigger** | Automatic/manual | Automatic/manual |

+    </DailyProvider>
+  );
+}
+
+### Phase 3: Testing & Validation
+
+For Phase 1 (feature parity), the existing processing pipeline remains unchanged:
+
+1. Daily.co records meeting to S3 (same as Whereby)
+2. Webhook notifies when recording is ready
+3. Existing pipeline downloads and processes the MP4 file
+4. Current diarization and transcription tools continue to work
+
+Key validation points:
+- Recording format matches (MP4 with mixed audio)
+- S3 paths are compatible
+- Processing pipeline requires no changes
+- Transcript quality remains the same
+
+## Future Enhancement: Raw-Tracks Recording (Phase 2)
+
+### Raw-Tracks Processing for Enhanced Diarization
+
+Daily.co's raw-tracks recording provides individual audio streams per participant, enabling:
+
+```python
+@shared_task
+def process_daily_raw_tracks(meeting_id: str, recording_id: str, tracks: list):
+    """Process Daily.co raw-tracks with perfect speaker attribution."""
+
+    for track in tracks:
+        participant_id = track["participant_id"]
+        participant_name = track["participant_name"]
+        track_url = track["download_url"]
+
+        # Download individual participant audio
+        response = download_track(track_url)
+
+        # Process with known speaker identity
+        transcript = transcribe_audio(
+            audio_data=response.content,
+            speaker_id=participant_id,
+            speaker_name=participant_name
+        )
+
+        # Store with accurate speaker mapping
+        save_transcript_segment(
+            meeting_id=meeting_id,
+            speaker_id=participant_id,
+            text=transcript.text,
+            timestamps=transcript.timestamps
+        )
+```
+
+### Benefits of Raw-Tracks (Future)
+
+1. **Deterministic Speaker Attribution**: Each audio track is already speaker-separated
+2. **Improved Transcription Accuracy**: Clean audio without cross-talk
+3. **Parallel Processing**: Process multiple speakers simultaneously
+4. **Better Metrics**: Accurate talk-time per participant
+
+### Phase 4: Database & Configuration
+
+#### 4.1 Environment Variable Updates
+
+Update `.env` files:
+
+```bash
+# Remove Whereby variables
+# WHEREBY_API_URL=https://api.whereby.dev/v1
+# WHEREBY_API_KEY=your-whereby-key
+# WHEREBY_WEBHOOK_SECRET=your-whereby-secret
+# AWS_WHEREBY_S3_BUCKET=whereby-recordings
+# AWS_WHEREBY_ACCESS_KEY_ID=whereby-key
+# AWS_WHEREBY_ACCESS_KEY_SECRET=whereby-secret
+
+# Add Daily.co variables
+DAILY_API_KEY=your-daily-api-key
+DAILY_WEBHOOK_SECRET=your-daily-webhook-secret
+AWS_DAILY_S3_BUCKET=daily-recordings
+AWS_DAILY_ROLE_ARN=arn:aws:iam::123456789:role/daily-recording-role
+AWS_REGION=us-west-2
+```
+
+#### 4.2 Database Migration
+
+```sql
+-- Alembic migration to support Daily.co
+-- server/alembic/versions/xxx_migrate_to_daily.py
+
+def upgrade():
+    # Add platform field to support gradual migration
+    op.add_column('rooms', sa.Column('platform', sa.String(), server_default='whereby'))
+    op.add_column('meetings', sa.Column('platform', sa.String(), server_default='whereby'))
+
+    # No other schema changes needed for feature parity
+
+def downgrade():
+    op.drop_column('meetings', 'platform')
+    op.drop_column('rooms', 'platform')
+```
+
+#### 4.3 Settings Update (`server/reflector/settings.py`)
+
+```python
+class Settings(BaseSettings):
+    # Remove Whereby settings
+    # WHEREBY_API_URL: str = "https://api.whereby.dev/v1"
+    # WHEREBY_API_KEY: str
+    # WHEREBY_WEBHOOK_SECRET: str
+    # AWS_WHEREBY_S3_BUCKET: str
+    # AWS_WHEREBY_ACCESS_KEY_ID: str
+    # AWS_WHEREBY_ACCESS_KEY_SECRET: str
+
+    # Add Daily.co settings
+    DAILY_API_KEY: str
+    DAILY_WEBHOOK_SECRET: str
+    AWS_DAILY_S3_BUCKET: str
+    AWS_DAILY_ROLE_ARN: str
+    AWS_REGION: str = "us-west-2"
+
+    # Daily.co room URL pattern
+    DAILY_ROOM_URL_PATTERN: str = "https://{subdomain}.daily.co/{room_name}"
+    DAILY_SUBDOMAIN: str = "reflector"  # Your Daily.co subdomain
+```
+
+## Technical Differences
+
+### Phase 1 Implementation
+1. **Frontend**: Replace `<whereby-embed>` custom element with Daily.co React components or iframe
+2. **Backend**: Create Daily.co API client matching Whereby's functionality
+3. **Webhooks**: Map Daily.co events to existing database operations
+4. **Recording**: Maintain same MP4 format and S3 storage
+
+### Phase 2 Capabilities (Future)
+1. **Raw-tracks recording**: Individual audio streams per participant
+2. **Presence API**: Real-time participant data without webhook delays
+3. **Transcription API**: Built-in transcription services
+4. **Advanced recording options**: Multiple formats and layouts
+
+## Risks and Mitigation
+
+### Risk 1: API Differences
+- **Mitigation**: Create abstraction layer to minimize changes
+- Comprehensive testing of all endpoints
+
+### Risk 2: Recording Format Changes
+- **Mitigation**: Build adapter for raw-tracks processing
+- Maintain backward compatibility during transition
+
+### Risk 3: User Experience Changes
+- **Mitigation**: A/B testing with gradual rollout
+- Feature parity checklist before full migration
+
+## Recommendation
+
+Migration to Daily.co is technically feasible and can be implemented in phases:
+
+### Phase 1: Feature Parity
+- Replace Whereby with Daily.co maintaining exact same functionality
+- Use standard cloud recording (MP4 to S3)
+- No changes to processing pipeline
+
+### Phase 2: Enhanced Capabilities (Future)
+- Enable raw-tracks recording for improved diarization
+- Implement participant-level audio processing
+- Add real-time features using Presence API
+
+## Next Steps
+
+1. Set up Daily.co account and obtain API credentials
+2. Implement feature flag system for gradual migration
+3. Create Daily.co API client matching Whereby functionality
+4. Update frontend to support both platforms
+5. Test thoroughly before rollout

-# Self-hosted Model API
-
-Run transcription, translation, and diarization services compatible with Reflector's GPU Model API. Works on CPU or GPU.
-
-Environment variables
-
-- REFLECTOR_GPU_APIKEY: Optional Bearer token. If unset, auth is disabled.
-- HF_TOKEN: Optional. Required for diarization to download pyannote pipelines
-
-Requirements
-
-- FFmpeg must be installed and on PATH (used for URL-based and segmented transcription)
-- Python 3.12+
-- NVIDIA GPU optional. If available, it will be used automatically
-
-Local run
-Set env vars in self_hosted/.env file
-uv sync
-
-uv run uvicorn main:app --host 0.0.0.0 --port 8000
-
-Authentication
-
-- If REFLECTOR_GPU_APIKEY is set, include header: Authorization: Bearer <key>
-
-Endpoints
-
-- POST /v1/audio/transcriptions
-
-  - multipart/form-data
-  - fields: file (single file) OR files[] (multiple files), language, batch (true/false)
-  - response: single { text, words, filename } or { results: [ ... ] }
-
-- POST /v1/audio/transcriptions-from-url
-
-  - application/json
-  - body: { audio_file_url, language, timestamp_offset }
-  - response: { text, words }
-
-- POST /translate
-
-  - text: query parameter
-  - body (application/json): { source_language, target_language }
-  - response: { text: { <src>: original, <tgt>: translated } }
-
-- POST /diarize
-  - query parameters: audio_file_url, timestamp (optional)
-  - requires HF_TOKEN to be set (for pyannote)
-  - response: { diarization: [ { start, end, speaker } ] }

-# Daily.co Integration Test Plan
-
-## ✅ IMPLEMENTATION STATUS: Real Transcription Active
-
-**This test validates Daily.co multitrack recording integration with REAL transcription/diarization.**
-
-The implementation includes complete audio processing pipeline:
-- **Multitrack recordings** from Daily.co S3 (separate audio stream per participant)
-- **PyAV-based audio mixdown** with PTS-based track alignment
-- **Real transcription** via Modal GPU backend (Whisper)
-- **Real diarization** via Modal GPU backend (speaker identification)
-- **Per-track transcription** with timestamp synchronization
-- **Complete database entities** (recording, transcript, topics, participants, words)
-
-**Processing pipeline** (`PipelineMainMultitrack`):
-1. Download all audio tracks from Daily.co S3
-2. Align tracks by PTS (presentation timestamp) to handle late joiners
-3. Mix tracks into single audio file for unified playback
-4. Transcribe each track individually with proper offset handling
-5. Perform diarization on mixed audio
-6. Generate topics, summaries, and word-level timestamps
-7. Convert audio to MP3 and generate waveform visualization
-
-**Note:** A stub processor (`process_daily_recording`) exists for testing webhook flow without GPU costs, but the production code path uses `process_multitrack_recording` with full ML pipeline.
-
----
-
-## Prerequisites
-
-**1. Environment Variables** (check in `.env.development.local`):
-```bash
-# Daily.co API Configuration

-## Test 7: Database Check - Recording and Transcript
-
-**Check recording created:**
-```bash
-docker-compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT id, bucket_name, object_key, status, meeting_id, recorded_at
-   FROM recording
-   ORDER BY recorded_at DESC LIMIT 1;"
-```
-
-**Expected:**
-```
-id: <recording-id-from-webhook>
-bucket_name: reflector-dailyco-local
-object_key: monadical/test2-<timestamp>/<recording-timestamp>-<uuid>-cam-audio-<track-start>.webm
-status: completed
-meeting_id: <meeting-id>
-recorded_at: <recent-timestamp>
-```
-
-**Check transcript created:**
-```bash
-docker compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT id, title, status, duration, recording_id, meeting_id, room_id
-   FROM transcript
-   ORDER BY created_at DESC LIMIT 1;"
-```
-
-**Expected (REAL transcription):**
-```
-id: <transcript-id>
-title: <AI-generated title based on actual conversation content>
-status: uploaded  (audio file processed and available)
-duration: <actual meeting duration in seconds>
-recording_id: <same-as-recording-id-above>
-meeting_id: <meeting-id>
-room_id: 552640fd-16f2-4162-9526-8cf40cd2357e
-```
-
-**Note:** Title and content will reflect the ACTUAL conversation, not mock data. Processing time depends on recording length and GPU backend availability (Modal).
-
-**Verify audio file exists:**
-```bash
-ls -lh data/<transcript-id>/upload.webm
-```
-
-**Expected:**
-```
--rw-r--r-- 1 user staff ~100-200K Oct 10 18:48 upload.webm
-```
-
-**Check transcript topics (REAL transcription):**
-```bash
-TRANSCRIPT_ID=$(docker compose exec -T postgres psql -U reflector -d reflector -t -c \
-  "SELECT id FROM transcript ORDER BY created_at DESC LIMIT 1;")
-
-docker compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT
-     jsonb_array_length(topics) as num_topics,
-     jsonb_array_length(participants) as num_participants,
-     short_summary,
-     title
-   FROM transcript
-   WHERE id = '$TRANSCRIPT_ID';"
-```
-
-**Expected (REAL data):**
-```
-num_topics: <varies based on conversation>
-num_participants: <actual number of participants who spoke>
-short_summary: <AI-generated summary of actual conversation>
-title: <AI-generated title based on content>
-```
-
-**Check topics contain actual transcription:**
-```bash
-docker compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT topics->0->'title', topics->0->'summary', topics->0->'transcript'
-   FROM transcript
-   ORDER BY created_at DESC LIMIT 1;" | head -20
-```
-
-**Expected output:** Will contain the ACTUAL transcribed conversation from the Daily.co meeting, not mock data.
-
-**Check participants:**
-```bash
-docker compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT participants FROM transcript ORDER BY created_at DESC LIMIT 1;" \
-  | python3 -c "import sys, json; data=json.loads(sys.stdin.read()); print(json.dumps(data, indent=2))"
-```
-
-**Expected (REAL diarization):**
-```json
-[
-  {
-    "id": "<uuid>",
-    "speaker": 0,
-    "name": "Speaker 1"
-  },
-  {
-    "id": "<uuid>",
-    "speaker": 1,
-    "name": "Speaker 2"
-  }
-]
-```
-
-**Note:** Speaker names will be generic ("Speaker 1", "Speaker 2", etc.) as determined by the diarization backend. Number of participants depends on how many actually spoke during the meeting.
-
-**Check word-level data:**
-```bash
-docker compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT jsonb_array_length(topics->0->'words') as num_words_first_topic
-   FROM transcript
-   ORDER BY created_at DESC LIMIT 1;"
-```
-
-**Expected:**
-```
-num_words_first_topic: <varies based on actual conversation length and topic chunking>
-```
-
-**Verify speaker diarization in words:**
-```bash
-docker compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT
-     topics->0->'words'->0->>'text' as first_word,
-     topics->0->'words'->0->>'speaker' as speaker,
-     topics->0->'words'->0->>'start' as start_time,
-     topics->0->'words'->0->>'end' as end_time
-   FROM transcript
-   ORDER BY created_at DESC LIMIT 1;"
-```
-
-**Expected (REAL transcription):**
-```
-first_word: <actual first word from transcription>
-speaker: 0, 1, 2, ... (actual speaker ID from diarization)
-start_time: <actual timestamp in seconds>
-end_time: <actual end timestamp>
-```
-
-**Note:** All timestamps and speaker IDs are from real transcription/diarization, synchronized across tracks.

-## Test 8: Recording Type Verification
-
-**Check what Daily.co received:**
-```bash
-curl -s -X GET "https://api.daily.co/v1/rooms/test2-<timestamp>" \
-  -H "Authorization: Bearer $DAILY_API_KEY" | python3 -m json.tool | grep "enable_recording"
-```
-
-**Expected:**
-```json
-"enable_recording": "raw-tracks"
-```
-
-**NOT:** `"enable_recording": "cloud"` (that would be wrong - we want raw tracks)
-
----
-
-## Troubleshooting
-
-### Issue: No webhooks received
-
-**Check webhook state:**
-```bash
-curl -s -X GET "https://api.daily.co/v1/webhooks" \
-  -H "Authorization: Bearer $DAILY_API_KEY" | python3 -m json.tool
-```
-
-**If state is FAILED:**
-```bash
-cd server
-uv run python scripts/recreate_daily_webhook.py https://<ngrok-url>/v1/daily/webhook
-```
-
-### Issue: Webhooks return 422
-
-**Check server logs:**
-```bash
-docker-compose logs --tail=50 server | grep "Failed to parse webhook event"
-```
-
-**Common cause:** Event structure mismatch. Daily.co events use:
-```json
-{
-  "version": "1.0.0",
-  "type": "participant.joined",
-  "payload": {...},  // NOT "data"
-  "event_ts": 123.456  // NOT "ts"
-}
-```
-
-### Issue: Recording not starting
-
-1. **Check token has `sr: true`:**
-   - Decode JWT token from room_url query param
-   - Should contain `"sr": true`
-
-2. **Check Daily.co room config:**
-   - `enable_recording` must be set (not false)
-   - For raw-tracks: must be exactly `"raw-tracks"`
-
-3. **Check participant actually joined:**
-   - Logs should show "Participant joined"
-   - Must click "Join" button, not just pre-call screen
-
-### Issue: Recording in S3 but wrong format
-
-**Daily.co recording types:**
-- `"cloud"` → Single MP4 file (`download_link` in webhook)
-- `"raw-tracks"` → Multiple WebM files (`tracks` array in webhook)
-- `"raw-tracks-audio-only"` → Only audio WebM files
-
-**Current implementation:** Always uses `"raw-tracks"` (better for transcription)
-
----
-
-## Quick Validation Commands
-
-**One-liner to verify everything:**
-```bash
-# 1. Check room exists
-docker-compose exec -T postgres psql -U reflector -d reflector -c \
-  "SELECT name, platform FROM room WHERE name = 'test2';" && \
-
-# 2. Create meeting
-MEETING=$(curl -s -X POST http://localhost:1250/v1/rooms/test2/meeting \
-  -H "Content-Type: application/json" -d '{"allow_duplicated":false}') && \
-echo "$MEETING" | python3 -c "import sys,json; m=json.load(sys.stdin); print(f'Room: {m[\"room_name\"]}\nURL: {m[\"room_url\"][:80]}...')" && \
-
-# 3. Check Daily.co config
-ROOM_NAME=$(echo "$MEETING" | python3 -c "import sys,json; print(json.load(sys.stdin)['room_name'])") && \
-curl -s -X GET "https://api.daily.co/v1/rooms/$ROOM_NAME" \
-  -H "Authorization: Bearer $DAILY_API_KEY" | python3 -c "import sys,json; print(f'Recording: {json.load(sys.stdin)[\"config\"][\"enable_recording\"]}')"
-```
-
-**Expected output:**
-```
-name: test2, platform: whereby
-Room: test2-20251009192341
-URL: https://monadical.daily.co/test2-20251009192341?t=eyJhbGc...
-Recording: raw-tracks
-```

-# Data Retention and Cleanup
-
-## Overview
-
-For public instances of Reflector, a data retention policy is automatically enforced to delete anonymous user data after a configurable period (default: 7 days). This ensures compliance with privacy expectations and prevents unbounded storage growth.
-
-## Configuration
-
-### Environment Variables
-
-- `PUBLIC_MODE` (bool): Must be set to `true` to enable automatic cleanup
-- `PUBLIC_DATA_RETENTION_DAYS` (int): Number of days to retain anonymous data (default: 7)
-
-### What Gets Deleted
-
-When data reaches the retention period, the following items are automatically removed:
-
-1. **Transcripts** from anonymous users (where `user_id` is NULL):
-   - Database records
-   - Local files (audio.wav, audio.mp3, audio.json waveform)
-   - Storage files (cloud storage if configured)
-
-## Automatic Cleanup
-
-### Celery Beat Schedule
-
-When `PUBLIC_MODE=true`, a Celery beat task runs daily at 3 AM to clean up old data:
-
-```python
-# Automatically scheduled when PUBLIC_MODE=true
-"cleanup_old_public_data": {
-    "task": "reflector.worker.cleanup.cleanup_old_public_data",
-    "schedule": crontab(hour=3, minute=0),  # Daily at 3 AM
-}
-```
-
-### Running the Worker
-
-Ensure both Celery worker and beat scheduler are running:
-
-```bash
-# Start Celery worker
-uv run celery -A reflector.worker.app worker --loglevel=info
-
-# Start Celery beat scheduler (in another terminal)
-uv run celery -A reflector.worker.app beat
-```
-
-## Manual Cleanup
-
-For testing or manual intervention, use the cleanup tool:
-
-```bash
-# Delete data older than 7 days (default)
-uv run python -m reflector.tools.cleanup_old_data
-
-# Delete data older than 30 days
-uv run python -m reflector.tools.cleanup_old_data --days 30
-```
-
-Note: The manual tool uses the same implementation as the Celery worker task to ensure consistency.
-
-## Important Notes
-
-1. **User Data Deletion**: Only anonymous data (where `user_id` is NULL) is deleted. Authenticated user data is preserved.
-
-2. **Storage Cleanup**: The system properly cleans up both local files and cloud storage when configured.
-
-3. **Error Handling**: If individual deletions fail, the cleanup continues and logs errors. Failed deletions are reported in the task output.
-
-4. **Public Instance Only**: The automatic cleanup task only runs when `PUBLIC_MODE=true` to prevent accidental data loss in private deployments.
-
-## Testing
-
-Run the cleanup tests:
-
-```bash
-uv run pytest tests/test_cleanup.py -v
-```
-
-## Monitoring
-
-Check Celery logs for cleanup task execution:
-
-```bash
-# Look for cleanup task logs
-grep "cleanup_old_public_data" celery.log
-grep "Starting cleanup of old public data" celery.log
-```
-
-Task statistics are logged after each run:
-- Number of transcripts deleted
-- Number of meetings deleted
-- Number of orphaned recordings deleted
-- Any errors encountered

-## Reflector GPU Transcription API (Specification)
-
-This document defines the Reflector GPU transcription API that all implementations must adhere to. Current implementations include NVIDIA Parakeet (NeMo) and Whisper (faster-whisper), both deployed on Modal.com. The API surface and response shapes are OpenAI/Whisper-compatible, so clients can switch implementations by changing only the base URL.
-
-### Base URL and Authentication
-
-- Example base URLs (Modal web endpoints):
-
-  - Parakeet: `https://<account>--reflector-transcriber-parakeet-web.modal.run`
-  - Whisper: `https://<account>--reflector-transcriber-web.modal.run`
-
-- All endpoints are served under `/v1` and require a Bearer token:
-
-```
-Authorization: Bearer <REFLECTOR_GPU_APIKEY>
-```
-
-Note: To switch implementations, deploy the desired variant and point `TRANSCRIPT_URL` to its base URL. The API is identical.
-
-### Supported file types
-
-`mp3, mp4, mpeg, mpga, m4a, wav, webm`
-
-### Models and languages
-
-- Parakeet (NVIDIA NeMo): default `nvidia/parakeet-tdt-0.6b-v2`
-  - Language support: only `en`. Other languages return HTTP 400.
-- Whisper (faster-whisper): default `large-v2` (or deployment-specific)
-  - Language support: multilingual (per Whisper model capabilities).
-
-Note: The `model` parameter is accepted by all implementations for interface parity. Some backends may treat it as informational.
-
-### Endpoints
-
-#### POST /v1/audio/transcriptions
-
-Transcribe one or more uploaded audio files.
-
-Request: multipart/form-data
-
-- `file` (File) — optional. Single file to transcribe.
-- `files` (File[]) — optional. One or more files to transcribe.
-- `model` (string) — optional. Defaults to the implementation-specific model (see above).
-- `language` (string) — optional, defaults to `en`.
-  - Parakeet: only `en` is accepted; other values return HTTP 400
-  - Whisper: model-dependent; typically multilingual
-- `batch` (boolean) — optional, defaults to `false`.
-
-Notes:
-
-- Provide either `file` or `files`, not both. If neither is provided, HTTP 400.
-- `batch` requires `files`; using `batch=true` without `files` returns HTTP 400.
-- Response shape for multiple files is the same regardless of `batch`.
-- Files sent to this endpoint are processed in a single pass (no VAD/chunking). This is intended for short clips (roughly ≤ 30s; depends on GPU memory/model). For longer audio, prefer `/v1/audio/transcriptions-from-url` which supports VAD-based chunking.
-
-Responses
-
-Single file response:
-
-```json
-{
-  "text": "transcribed text",
-  "words": [
-    { "word": "hello", "start": 0.0, "end": 0.5 },
-    { "word": "world", "start": 0.5, "end": 1.0 }
-  ],
-  "filename": "audio.mp3"
-}
-```
-
-Multiple files response:
-
-```json
-{
-  "results": [
-    {"filename": "a1.mp3", "text": "...", "words": [...]},
-    {"filename": "a2.mp3", "text": "...", "words": [...]}]
-}
-```
-
-Notes:
-
-- Word objects always include keys: `word`, `start`, `end`.
-- Some implementations may include a trailing space in `word` to match Whisper tokenization behavior; clients should trim if needed.
-
-Example curl (single file):
-
-```bash
-curl -X POST \
-  -H "Authorization: Bearer $REFLECTOR_GPU_APIKEY" \
-  -F "file=@/path/to/audio.mp3" \
-  -F "language=en" \
-  "$BASE_URL/v1/audio/transcriptions"
-```
-
-Example curl (multiple files, batch):
-
-```bash
-curl -X POST \
-  -H "Authorization: Bearer $REFLECTOR_GPU_APIKEY" \
-  -F "files=@/path/a1.mp3" -F "files=@/path/a2.mp3" \
-  -F "batch=true" -F "language=en" \
-  "$BASE_URL/v1/audio/transcriptions"
-```
-
-#### POST /v1/audio/transcriptions-from-url
-
-Transcribe a single remote audio file by URL.
-
-Request: application/json
-
-Body parameters:
-
-- `audio_file_url` (string) — required. URL of the audio file to transcribe.
-- `model` (string) — optional. Defaults to the implementation-specific model (see above).
-- `language` (string) — optional, defaults to `en`. Parakeet only accepts `en`.
-- `timestamp_offset` (number) — optional, defaults to `0.0`. Added to each word's `start`/`end` in the response.
-
-```json
-{
-  "audio_file_url": "https://example.com/audio.mp3",
-  "model": "nvidia/parakeet-tdt-0.6b-v2",
-  "language": "en",
-  "timestamp_offset": 0.0
-}
-```
-
-Response:
-
-```json
-{
-  "text": "transcribed text",
-  "words": [
-    { "word": "hello", "start": 10.0, "end": 10.5 },
-    { "word": "world", "start": 10.5, "end": 11.0 }
-  ]
-}
-```
-
-Notes:
-
-- `timestamp_offset` is added to each word’s `start`/`end` in the response.
-- Implementations may perform VAD-based chunking and batching for long-form audio; word timings are adjusted accordingly.
-
-Example curl:
-
-```bash
-curl -X POST \
-  -H "Authorization: Bearer $REFLECTOR_GPU_APIKEY" \
-  -H "Content-Type: application/json" \
-  -d '{
-        "audio_file_url": "https://example.com/audio.mp3",
-        "language": "en",
-        "timestamp_offset": 0
-      }' \
-  "$BASE_URL/v1/audio/transcriptions-from-url"
-```
-
-### Error handling
-
-- 400 Bad Request
-  - Parakeet: `language` other than `en`
-  - Missing required parameters (`file`/`files` for upload; `audio_file_url` for URL endpoint)
-  - Unsupported file extension
-- 401 Unauthorized
-  - Missing or invalid Bearer token
-- 404 Not Found
-  - `audio_file_url` does not exist
-
-### Implementation details
-
-- GPUs: A10G for small-file/live, L40S for large-file URL transcription (subject to deployment)
-- VAD chunking and segment batching; word timings adjusted and overlapping ends constrained
-- Pads very short segments (< 0.5s) to avoid model crashes on some backends
-
-### Server configuration (Reflector API)
-
-Set the Reflector server to use the Modal backend and point `TRANSCRIPT_URL` to your chosen deployment:
-
-```
-TRANSCRIPT_BACKEND=modal
-TRANSCRIPT_URL=https://<account>--reflector-transcriber-parakeet-web.modal.run
-TRANSCRIPT_MODAL_API_KEY=<REFLECTOR_GPU_APIKEY>
-```
-
-### Conformance tests
-
-Use the pytest-based conformance tests to validate any new implementation (including self-hosted) against this spec:
-
-```
-TRANSCRIPT_URL=https://<your-deployment-base> \
-TRANSCRIPT_MODAL_API_KEY=your-api-key \
-uv run -m pytest -m model_api --no-cov server/tests/test_model_api_transcript.py

-# Reflector Webhook Documentation
-
-## Overview
-
-Reflector supports webhook notifications to notify external systems when transcript processing is completed. Webhooks can be configured per room and are triggered automatically after a transcript is successfully processed.
-
-## Configuration
-
-Webhooks are configured at the room level with two fields:
-- `webhook_url`: The HTTPS endpoint to receive webhook notifications
-- `webhook_secret`: Optional secret key for HMAC signature verification (auto-generated if not provided)
-
-## Events
-
-### `transcript.completed`
-
-Triggered when a transcript has been fully processed, including transcription, diarization, summarization, topic detection and calendar event integration.
-
-### `test`
-
-A test event that can be triggered manually to verify webhook configuration.
-
-## Webhook Request Format
-
-### Headers
-
-All webhook requests include the following headers:
-
-| Header | Description | Example |
-|--------|-------------|---------|
-| `Content-Type` | Always `application/json` | `application/json` |
-| `User-Agent` | Identifies Reflector as the source | `Reflector-Webhook/1.0` |
-| `X-Webhook-Event` | The event type | `transcript.completed` or `test` |
-| `X-Webhook-Retry` | Current retry attempt number | `0`, `1`, `2`... |
-| `X-Webhook-Signature` | HMAC signature (if secret configured) | `t=1735306800,v1=abc123...` |
-
-### Signature Verification
-
-If a webhook secret is configured, Reflector includes an HMAC-SHA256 signature in the `X-Webhook-Signature` header to verify the webhook authenticity.
-
-The signature format is: `t={timestamp},v1={signature}`
-
-To verify the signature:
-1. Extract the timestamp and signature from the header
-2. Create the signed payload: `{timestamp}.{request_body}`
-3. Compute HMAC-SHA256 of the signed payload using your webhook secret
-4. Compare the computed signature with the received signature
-
-Example verification (Python):
-```python
-import hmac
-import hashlib

-}
-```
-
-## Retry Policy
-
-Webhooks are delivered with automatic retry logic to handle transient failures. When a webhook delivery fails due to server errors or network issues, Reflector will automatically retry the delivery multiple times over an extended period.
-
-### Retry Mechanism
-
-Reflector implements an exponential backoff strategy for webhook retries:
-
-- **Initial retry delay**: 60 seconds after the first failure
-- **Exponential backoff**: Each subsequent retry waits approximately twice as long as the previous one
-- **Maximum retry interval**: 1 hour (backoff is capped at this duration)
-- **Maximum retry attempts**: 30 attempts total
-- **Total retry duration**: Retries continue for approximately 24 hours
-
-### How Retries Work
-
-When a webhook fails, Reflector will:
-1. Wait 60 seconds, then retry (attempt #1)
-2. If it fails again, wait ~2 minutes, then retry (attempt #2)
-3. Continue doubling the wait time up to a maximum of 1 hour between attempts
-4. Keep retrying at 1-hour intervals until successful or 30 attempts are exhausted
-
-The `X-Webhook-Retry` header indicates the current retry attempt number (0 for the initial attempt, 1 for first retry, etc.), allowing your endpoint to track retry attempts.
-
-### Retry Behavior by HTTP Status Code
-
-| Status Code | Behavior |
-|-------------|----------|
-| 2xx (Success) | No retry, webhook marked as delivered |
-| 4xx (Client Error) | No retry, request is considered permanently failed |
-| 5xx (Server Error) | Automatic retry with exponential backoff |
-| Network/Timeout Error | Automatic retry with exponential backoff |
-
-**Important Notes:**
-- Webhooks timeout after 30 seconds. If your endpoint takes longer to respond, it will be considered a timeout error and retried.
-- During the retry period (~24 hours), you may receive the same webhook multiple times if your endpoint experiences intermittent failures.
-- There is no mechanism to manually retry failed webhooks after the retry period expires.
-
-## Testing Webhooks
-
-You can test your webhook configuration before processing transcripts:
-
-```http
-POST /v1/rooms/{room_id}/webhook/test
-```
-
-Response:
-```json
-{
-  "success": true,
-  "status_code": 200,
-  "message": "Webhook test successful",
-  "response_preview": "OK"
-}
-```
-
-Or in case of failure:
-```json
-{
-  "success": false,
-  "error": "Webhook request timed out (10 seconds)"
-}
-```

+# Reflector GPU implementation - Transcription and LLM
+
+This repository hold an API for the GPU implementation of the Reflector API service,
+and use [Modal.com](https://modal.com)
+
+- `reflector_diarizer.py` - Diarization API
+- `reflector_transcriber.py` - Transcription API
+- `reflector_translator.py` - Translation API
+
+## Modal.com deployment
+
+Create a modal secret, and name it `reflector-gpu`.
+It should contain an `REFLECTOR_APIKEY` environment variable with a value.
+
+The deployment is done using [Modal.com](https://modal.com) service.
+
+```
+$ modal deploy reflector_transcriber.py
+...
+└── 🔨 Created web => https://xxxx--reflector-transcriber-web.modal.run
+
+$ modal deploy reflector_llm.py
+...
+└── 🔨 Created web => https://xxxx--reflector-llm-web.modal.run
+```
+
+Then in your reflector api configuration `.env`, you can set theses keys:
+
+```
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=https://xxxx--reflector-transcriber-web.modal.run
+TRANSCRIPT_MODAL_API_KEY=REFLECTOR_APIKEY
+
+LLM_BACKEND=modal
+LLM_URL=https://xxxx--reflector-llm-web.modal.run
+LLM_MODAL_API_KEY=REFLECTOR_APIKEY
+```
+
+## API
+
+Authentication must be passed with the `Authorization` header, using the `bearer` scheme.
+
+```
+Authorization: bearer <REFLECTOR_APIKEY>
+```
+
+### LLM
+
+`POST /llm`

+}
+```
+
+### Transcription
+
+`POST /transcribe`
+

-# Multitrack Pipeline Fix Summary
-
-## Problem
-Whisper timestamps were incorrect because it ignores leading silence in audio files. Daily.co tracks can have arbitrary amounts of silence before speech starts.
-
-## Solution
-**Pad tracks BEFORE transcription using stream metadata `start_time`**
-
-This makes Whisper timestamps automatically correct relative to recording start.
-
-## Key Changes in `main_multitrack_pipeline_fixed.py`
-
-### 1. Added `pad_track_for_transcription()` method (lines 55-172)
-
-```python
-async def pad_track_for_transcription(
-    self,
-    track_data: bytes,
-    track_idx: int,
-    storage,
-) -> tuple[bytes, str]:
-```
-
-- Extracts stream metadata `start_time` using PyAV
-- Creates PyAV filter graph with `adelay` filter to add padding
-- Stores padded track to S3 and returns URL
-- Uses same audio processing library (PyAV) already in the pipeline
-
-### 2. Modified `process()` method
-
-#### REMOVED (lines 255-302):
-- Entire filename parsing for offsets - NOT NEEDED ANYMORE
-- The complex regex parsing of Daily.co filenames
-- Offset adjustment after transcription
-
-#### ADDED (lines 371-382):
-- Padding step BEFORE transcription:
-```python
-# PAD TRACKS BEFORE TRANSCRIPTION - THIS IS THE KEY FIX!
-padded_track_urls: list[str] = []
-for idx, data in enumerate(track_datas):
-    if not data:
-        padded_track_urls.append("")
-        continue
-
-    _, padded_url = await self.pad_track_for_transcription(
-        data, idx, storage
-    )
-    padded_track_urls.append(padded_url)
-```
-
-#### MODIFIED (lines 385-435):
-- Transcribe PADDED tracks instead of raw tracks
-- Removed all timestamp offset adjustment code
-- Just set speaker ID - timestamps already correct!
-
-```python
-# NO OFFSET ADJUSTMENT NEEDED!
-# Timestamps are already correct because we transcribed padded tracks
-# Just set speaker ID
-for w in t.words:
-    w.speaker = idx
-```
-
-## Why This Works
-
-1. **Stream metadata is authoritative**: Daily.co sets `start_time` in the WebM container
-2. **PyAV respects metadata**: `audio_stream.start_time * audio_stream.time_base` gives seconds
-3. **Padding before transcription**: Whisper sees continuous audio from time 0
-4. **Automatic alignment**: Word at 51s in padded track = 51s in recording
-
-## Testing
-
-Process the test recording (daily-20251020193458) and verify:
-- Participant 0 words appear at ~2s
-- Participant 1 words appear at ~51s
-- No word interleaving
-- Correct chronological order
-
