fix: resolve session management issues in tests and WebSocket endpoints

- Add missing db_session parameter to test_pipeline_main_file.py tests
- Fix WebSocket endpoint missing session dependency injection
- Update test fixtures to pass session as first argument to pipeline.process()
- Add required imports (Depends, AsyncSession, get_session) to transcripts_websocket.py

Note: 2 WebRTC tests still failing due to known asyncio event loop issues with SQLAlchemy

+
+## Feature Flags
+
+Reflector uses environment variable-based feature flags to control application functionality. These flags allow you to enable or disable features without code changes.
+
+### Available Feature Flags
+
+| Feature Flag | Environment Variable |
+|-------------|---------------------|
+| `requireLogin` | `NEXT_PUBLIC_FEATURE_REQUIRE_LOGIN` |
+| `privacy` | `NEXT_PUBLIC_FEATURE_PRIVACY` |
+| `browse` | `NEXT_PUBLIC_FEATURE_BROWSE` |
+| `sendToZulip` | `NEXT_PUBLIC_FEATURE_SEND_TO_ZULIP` |
+| `rooms` | `NEXT_PUBLIC_FEATURE_ROOMS` |
+
+### Setting Feature Flags
+
+Feature flags are controlled via environment variables using the pattern `NEXT_PUBLIC_FEATURE_{FEATURE_NAME}` where `{FEATURE_NAME}` is the SCREAMING_SNAKE_CASE version of the feature name.
+
+**Examples:**
+```bash
+# Enable user authentication requirement
+NEXT_PUBLIC_FEATURE_REQUIRE_LOGIN=true
+
+# Disable browse functionality
+NEXT_PUBLIC_FEATURE_BROWSE=false
+
+# Enable Zulip integration
+NEXT_PUBLIC_FEATURE_SEND_TO_ZULIP=true
+```

+# AsyncIO Event Loop Analysis for test_attendee_parsing_bug.py
+
+## Problem Summary
+The test passes but encounters an error during teardown where asyncpg tries to use a different/closed event loop, resulting in:
+- `RuntimeError: Task got Future attached to a different loop`
+- `RuntimeError: Event loop is closed`
+
+## Root Cause Analysis
+
+### 1. Multiple Event Loop Creation Points
+
+The test environment creates event loops at different scopes:
+
+1. **Session-scoped loop** (conftest.py:27-34):
+   - Created once per test session
+   - Used by session-scoped fixtures
+   - Closed after all tests complete
+
+2. **Function-scoped loop** (pytest-asyncio default):
+   - Created for each async test function
+   - This is the loop that runs the actual test
+   - Closed immediately after test completes
+
+3. **AsyncPG internal loop**:
+   - AsyncPG connections store a reference to the loop they were created with
+   - Used for connection lifecycle management
+
+### 2. Event Loop Lifecycle Mismatch
+
+The issue occurs because:
+
+1. **Session fixture creates database connection** on session-scoped loop
+2. **Test runs** on function-scoped loop (different from session loop)
+3. **During teardown**, the session fixture tries to rollback/close using the original session loop
+4. **AsyncPG connection** still references the function-scoped loop which is now closed
+5. **Conflict**: SQLAlchemy tries to use session loop, but asyncpg Future is attached to the closed function loop
+
+### 3. Configuration Issues
+
+Current pytest configuration:
+- `asyncio_mode = "auto"` in pyproject.toml
+- `asyncio_default_fixture_loop_scope=session` (shown in test output)
+- `asyncio_default_test_loop_scope=function` (shown in test output)
+
+This mismatch between fixture loop scope (session) and test loop scope (function) causes the problem.
+
+## Solutions
+
+### Option 1: Align Loop Scopes (Recommended)
+Change pytest-asyncio configuration to use consistent loop scopes:
+
+```python
+# pyproject.toml
+[tool.pytest.ini_options]
+asyncio_mode = "auto"
+asyncio_default_fixture_loop_scope = "function"  # Change from session to function
+```
+
+### Option 2: Use Function-Scoped Database Fixture
+Change the `session` fixture scope from session to function:
+
+```python
+@pytest_asyncio.fixture  # Remove scope="session"
+async def session(setup_database):
+    # ... existing code ...
+```
+
+### Option 3: Explicit Loop Management
+Ensure all async operations use the same loop:
+
+```python
+@pytest_asyncio.fixture
+async def session(setup_database, event_loop):
+    # Force using the current event loop
+    engine = create_async_engine(
+        settings.DATABASE_URL,
+        echo=False,
+        poolclass=NullPool,
+        connect_args={"loop": event_loop}  # Pass explicit loop
+    )
+    # ... rest of fixture ...
+```
+
+### Option 4: Upgrade pytest-asyncio
+The current version (1.1.0) has known issues with loop management. Consider upgrading to the latest version which has better loop scope handling.
+
+## Immediate Workaround
+
+For the test to run cleanly without the teardown error, you can:
+
+1. Add explicit cleanup in the test:
+```python
+@pytest.mark.asyncio
+async def test_attendee_parsing_bug(session):
+    # ... existing test code ...
+
+    # Explicit cleanup before fixture teardown
+    await session.commit()  # or await session.close()
+```
+
+2. Or suppress the teardown error (not recommended for production):
+```python
+@pytest.fixture
+async def session(setup_database):
+    # ... existing setup ...
+    try:
+        yield session
+        await session.rollback()
+    except RuntimeError as e:
+        if "Event loop is closed" not in str(e):
+            raise
+    finally:
+        await session.close()
+```
+
+## Recommendation
+
+The cleanest solution is to align the loop scopes by setting both fixture and test loop scopes to "function" scope. This ensures each test gets its own clean event loop and avoids cross-contamination between tests.

+## 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
+```

+# Celery to TaskIQ Migration Guide
+
+## Executive Summary
+
+This document outlines the migration path from Celery to TaskIQ for the Reflector project. TaskIQ is a modern, async-first distributed task queue that provides similar functionality to Celery while being designed specifically for async Python applications.
+
+## Current Celery Usage Analysis
+
+### Key Patterns in Use
+1. **Task Decorators**: `@shared_task`, `@asynctask`, `@with_session` decorators
+2. **Task Invocation**: `.delay()`, `.si()` for signatures
+3. **Workflow Patterns**: `chain()`, `group()`, `chord()` for complex pipelines
+4. **Scheduled Tasks**: Celery Beat with crontab and periodic schedules
+5. **Session Management**: Custom `@with_session` and `@with_session_and_transcript` decorators
+6. **Retry Logic**: Auto-retry with exponential backoff
+7. **Redis Backend**: Using Redis for broker and result backend
+
+### Critical Files to Migrate
+- `reflector/worker/app.py` - Celery app configuration and beat schedule
+- `reflector/worker/session_decorator.py` - Session management decorators
+- `reflector/pipelines/main_file_pipeline.py` - File processing pipeline
+- `reflector/pipelines/main_live_pipeline.py` - Live streaming pipeline (10 tasks)
+- `reflector/worker/process.py` - Background processing tasks
+- `reflector/worker/ics_sync.py` - Calendar sync tasks
+- `reflector/worker/cleanup.py` - Cleanup tasks
+- `reflector/worker/webhook.py` - Webhook notifications
+
+## TaskIQ Architecture Mapping
+
+### 1. Installation
+
+```bash
+# Remove Celery dependencies
+uv remove celery flower
+
+# Install TaskIQ with Redis support
+uv add taskiq taskiq-redis taskiq-pipelines
+```
+
+### 2. Broker Configuration
+
+#### Current (Celery)
+```python
+# reflector/worker/app.py
+from celery import Celery
+
+app = Celery(
+    "reflector",
+    broker=settings.CELERY_BROKER_URL,
+    backend=settings.CELERY_RESULT_BACKEND,
+    include=[...],
+)
+```
+
+#### New (TaskIQ)
+```python
+# reflector/worker/broker.py
+from taskiq_redis import RedisAsyncResultBackend, RedisStreamBroker
+from taskiq import PipelineMiddleware, SimpleRetryMiddleware
+
+result_backend = RedisAsyncResultBackend(
+    redis_url=settings.REDIS_URL,
+    result_ex_time=86400,  # 24 hours
+)
+
+broker = RedisStreamBroker(
+    url=settings.REDIS_URL,
+    max_connection_pool_size=10,
+).with_result_backend(result_backend).with_middlewares(
+    PipelineMiddleware(),  # For chain/group/chord support
+    SimpleRetryMiddleware(default_retry_count=3),
+)
+
+# For testing environment
+if os.environ.get("ENVIRONMENT") == "pytest":
+    from taskiq import InMemoryBroker
+    broker = InMemoryBroker(await_inplace=True)
+```
+
+### 3. Task Definition Migration
+
+#### Current (Celery)
+```python
+@shared_task
+@asynctask
+@with_session
+async def task_pipeline_file_process(session: AsyncSession, transcript_id: str):
+    pipeline = PipelineMainFile(transcript_id=transcript_id)
+    await pipeline.process()
+```
+
+#### New (TaskIQ)
+```python
+from taskiq import TaskiqDepends
+from reflector.worker.broker import broker
+from reflector.worker.dependencies import get_db_session
+
+@broker.task
+async def task_pipeline_file_process(transcript_id: str):
+    # Use get_session for proper test mocking
+    async for session in get_session():
+        pipeline = PipelineMainFile(transcript_id=transcript_id)
+        await pipeline.process()
+```
+
+### 4. Session Management
+
+#### Current Session Decorators (Keep Using These!)
+```python
+# reflector/worker/session_decorator.py
+def with_session(func):
+    @functools.wraps(func)
+    async def wrapper(*args, **kwargs):
+        async with get_session_context() as session:
+            return await func(session, *args, **kwargs)
+    return wrapper
+```
+
+#### Session Management Strategy
+
+**⚠️ CRITICAL**: The key insight is to maintain consistent session management patterns:
+
+1. **For Worker Tasks**: Continue using `@with_session` decorator pattern
+2. **For FastAPI endpoints**: Use `get_session` dependency injection
+3. **Never use `get_session_factory()` directly** in application code
+
+```python
+# APPROACH 1: Simple migration keeping decorator pattern
+from reflector.worker.session_decorator import with_session
+
+@taskiq_broker.task
+@with_session
+async def task_pipeline_file_process(session, *, transcript_id: str):
+    # Session is provided by decorator, just like Celery version
+    transcript = await transcripts_controller.get_by_id(session, transcript_id)
+    pipeline = PipelineMainFile(transcript_id=transcript_id)
+    await pipeline.process()
+
+# APPROACH 2: For test compatibility without decorator
+from reflector.db import get_session
+
+@taskiq_broker.task
+async def task_pipeline_file_process(transcript_id: str):
+    # Use get_session which is mocked in tests
+    async for session in get_session():
+        transcript = await transcripts_controller.get_by_id(session, transcript_id)
+        pipeline = PipelineMainFile(transcript_id=transcript_id)
+        await pipeline.process()
+
+# APPROACH 3: Future - TaskIQ dependency injection (after full migration)
+from taskiq import TaskiqDepends
+
+async def get_session_context():
+    """Context manager version of get_session for consistency"""
+    async for session in get_session():
+        yield session
+
+@taskiq_broker.task
+async def task_pipeline_file_process(
+    transcript_id: str,
+    session: AsyncSession = TaskiqDepends(get_session_context)
+):
+    transcript = await transcripts_controller.get_by_id(session, transcript_id)
+    pipeline = PipelineMainFile(transcript_id=transcript_id)
+    await pipeline.process()
+```
+
+**Key Points:**
+- `@with_session` decorator works with TaskIQ tasks (remove `@asynctask`, keep `@with_session`)
+- For testing: `get_session()` from `reflector.db` is properly mocked
+- Never call `get_session_factory()` directly - always use the abstractions
+
+### 5. Task Invocation
+
+#### Current (Celery)
+```python
+# Simple async execution
+task_pipeline_file_process.delay(transcript_id=transcript.id)
+
+# With signature for chaining
+task_cleanup_consent.si(transcript_id=transcript_id)
+```
+
+#### New (TaskIQ)
+```python
+# Simple async execution
+await task_pipeline_file_process.kiq(transcript_id=transcript.id)
+
+# With kicker for advanced configuration
+await task_cleanup_consent.kicker().with_labels(
+    priority="high"
+).kiq(transcript_id=transcript_id)
+```
+
+### 6. Workflow Patterns (Chain, Group, Chord)
+
+#### Current (Celery)
+```python
+from celery import chain, group, chord
+
+# Chain example
+post_chain = chain(
+    task_cleanup_consent.si(transcript_id=transcript_id),
+    task_pipeline_post_to_zulip.si(transcript_id=transcript_id),
+    task_send_webhook_if_needed.si(transcript_id=transcript_id),
+)
+
+# Chord example (parallel + callback)
+chain = chord(
+    group(chain_mp3_and_diarize, chain_title_preview),
+    chain_final_summaries,
+) | task_pipeline_post_to_zulip.si(transcript_id=transcript_id)
+```
+
+#### New (TaskIQ with Pipelines)
+```python
+from taskiq_pipelines import Pipeline
+from taskiq import gather
+
+# Chain example using Pipeline
+post_pipeline = (
+    Pipeline(broker, task_cleanup_consent)
+    .call_next(task_pipeline_post_to_zulip, transcript_id=transcript_id)
+    .call_next(task_send_webhook_if_needed, transcript_id=transcript_id)
+)
+await post_pipeline.kiq(transcript_id=transcript_id)
+
+# Parallel execution with gather
+results = await gather([
+    chain_mp3_and_diarize.kiq(transcript_id),
+    chain_title_preview.kiq(transcript_id),
+])
+
+# Then execute callback
+await chain_final_summaries.kiq(transcript_id, results)
+await task_pipeline_post_to_zulip.kiq(transcript_id)
+```
+
+### 7. Scheduled Tasks (Celery Beat → TaskIQ Scheduler)
+
+#### Current (Celery Beat)
+```python
+# reflector/worker/app.py
+app.conf.beat_schedule = {
+    "process_messages": {
+        "task": "reflector.worker.process.process_messages",
+        "schedule": float(settings.SQS_POLLING_TIMEOUT_SECONDS),
+    },
+    "reprocess_failed_recordings": {
+        "task": "reflector.worker.process.reprocess_failed_recordings",
+        "schedule": crontab(hour=5, minute=0),
+    },
+}
+```
+
+#### New (TaskIQ Scheduler)
+```python
+# reflector/worker/scheduler.py
+from taskiq import TaskiqScheduler
+from taskiq_redis import ListRedisScheduleSource
+
+schedule_source = ListRedisScheduleSource(settings.REDIS_URL)
+
+# Define scheduled tasks with decorators
+@broker.task(
+    schedule=[
+        {
+            "cron": f"*/{int(settings.SQS_POLLING_TIMEOUT_SECONDS)} * * * * *"
+        }
+    ]
+)
+async def process_messages():
+    # Task implementation
+    pass
+
+@broker.task(
+    schedule=[{"cron": "0 5 * * *"}]  # Daily at 5 AM
+)
+async def reprocess_failed_recordings():
+    # Task implementation
+    pass
+
+# Initialize scheduler
+scheduler = TaskiqScheduler(broker, sources=[schedule_source])
+
+# Run scheduler (separate process)
+# taskiq scheduler reflector.worker.scheduler:scheduler
+```
+
+### 8. Retry Configuration
+
+#### Current (Celery)
+```python
+@shared_task(
+    bind=True,
+    max_retries=30,
+    default_retry_delay=60,
+    retry_backoff=True,
+    retry_backoff_max=3600,
+)
+async def task_send_webhook_if_needed(self, ...):
+    try:
+        # Task logic
+    except Exception as exc:
+        raise self.retry(exc=exc)
+```
+
+#### New (TaskIQ)
+```python
+from taskiq.middlewares import SimpleRetryMiddleware
+
+# Global middleware configuration (1:1 with Celery defaults)
+broker = broker.with_middlewares(
+    SimpleRetryMiddleware(default_retry_count=3),
+)
+
+# For specific tasks with custom retry logic:
+@broker.task(retry_on_error=True, max_retries=30)
+async def task_send_webhook_if_needed(...):
+    # Task logic - exceptions auto-retry
+    pass
+```
+
+## Testing Migration
+
+### Current Pytest Setup (Celery)
+```python
+# tests/conftest.py
+@pytest.fixture(scope="session")
+def celery_config():
+    return {
+        "broker_url": "memory://",
+        "result_backend": "cache+memory://",
+    }
+
+@pytest.mark.usefixtures("celery_session_app")
+@pytest.mark.usefixtures("celery_session_worker")
+async def test_task():
+    pass
+```
+
+### New Pytest Setup (TaskIQ)
+```python
+# tests/conftest.py
+import pytest
+from taskiq import InMemoryBroker
+from reflector.worker.broker import broker
+
+@pytest.fixture(scope="function", autouse=True)
+async def setup_taskiq_broker():
+    """Replace broker with InMemoryBroker for testing"""
+    original_broker = broker
+    test_broker = InMemoryBroker(await_inplace=True)
+
+    # Copy task registrations
+    for task_name, task in original_broker._tasks.items():
+        test_broker.register_task(task.original_function, task_name=task_name)
+
+    yield test_broker
+    await test_broker.shutdown()
+
+@pytest.fixture
+async def taskiq_with_db_session(db_session):
+    """Setup TaskIQ with database session"""
+    from reflector.worker.broker import broker
+    broker.add_dependency_context({
+        AsyncSession: db_session
+    })
+    yield
+    broker.custom_dependency_context = {}
+
+# Test example
+@pytest.mark.anyio
+async def test_task(taskiq_with_db_session):
+    result = await task_pipeline_file_process("transcript-id")
+    assert result is not None
+```
+
+## Migration Steps
+
+### Phase 1: Setup (Week 1)
+1. **Install TaskIQ packages**
+   ```bash
+   uv add taskiq taskiq-redis taskiq-pipelines
+   ```
+
+2. **Create new broker configuration**
+   - Create `reflector/worker/broker.py` with TaskIQ broker setup
+   - Create `reflector/worker/dependencies.py` for dependency injection
+
+3. **Update settings**
+   - Keep existing Redis configuration
+   - Add TaskIQ-specific settings if needed
+
+### Phase 2: Parallel Running (Week 2-3)
+1. **Migrate simple tasks first**
+   - Start with `cleanup.py` (1 task)
+   - Move to `webhook.py` (1 task)
+   - Test thoroughly in isolation
+
+2. **Setup dual-mode operation**
+   - Keep Celery tasks running
+   - Add TaskIQ versions alongside
+   - Use feature flags to switch between them
+
+### Phase 3: Complex Tasks (Week 3-4)
+1. **Migrate pipeline tasks**
+   - Convert `main_file_pipeline.py`
+   - Convert `main_live_pipeline.py` (most complex with 10 tasks)
+   - Ensure chain/group/chord patterns work
+
+2. **Migrate scheduled tasks**
+   - Setup TaskIQ scheduler
+   - Convert beat schedule to TaskIQ schedules
+   - Test cron patterns
+
+### Phase 4: Testing & Validation (Week 4-5)
+1. **Update test suite**
+   - Replace Celery fixtures with TaskIQ fixtures
+   - Update all test files
+   - Ensure coverage remains the same
+
+2. **Performance testing**
+   - Compare task execution times
+   - Monitor Redis memory usage
+   - Test under load
+
+### Phase 5: Cutover (Week 5-6)
+1. **Final migration**
+   - Remove Celery dependencies
+   - Update deployment scripts
+   - Update documentation
+
+2. **Monitoring**
+   - Setup TaskIQ monitoring (if available)
+   - Create health checks
+   - Document operational procedures
+
+## Key Differences to Note
+
+### Advantages of TaskIQ
+1. **Native async support** - No need for `@asynctask` wrapper
+2. **Dependency injection** - Cleaner than decorators for session management
+3. **Type hints** - Better IDE support and autocompletion
+4. **Modern Python** - Designed for Python 3.7+
+5. **Simpler testing** - InMemoryBroker makes testing easier
+
+### Potential Challenges
+1. **Less mature ecosystem** - Fewer third-party integrations
+2. **Documentation** - Less comprehensive than Celery
+3. **Monitoring tools** - No Flower equivalent (may need custom solution)
+4. **Community support** - Smaller community than Celery
+
+## Command Line Changes
+
+### Current (Celery)
+```bash
+# Start worker
+celery -A reflector.worker.app worker --loglevel=info
+
+# Start beat scheduler
+celery -A reflector.worker.app beat
+```
+
+### New (TaskIQ)
+```bash
+# Start worker
+taskiq worker reflector.worker.broker:broker
+
+# Start scheduler
+taskiq scheduler reflector.worker.scheduler:scheduler
+
+# With custom settings
+taskiq worker reflector.worker.broker:broker --workers 4 --log-level INFO
+```
+
+## Rollback Plan
+
+If issues arise during migration:
+
+1. **Keep Celery code in version control** - Tag the last Celery version
+2. **Maintain dual broker setup** - Can switch back via environment variable
+3. **Database compatibility** - No schema changes required
+4. **Redis compatibility** - Both use Redis, easy to switch back
+
+## Success Criteria
+
+1. ✅ All tasks migrated and functioning
+2. ✅ Test coverage maintained at current levels
+3. ✅ Performance equal or better than Celery
+4. ✅ Scheduled tasks running reliably
+5. ✅ Error handling and retries working correctly
+6. ✅ WebSocket notifications still functioning
+7. ✅ Pipeline processing maintaining same behavior
+
+## Monitoring & Operations
+
+### Health Checks
+```python
+# reflector/worker/healthcheck.py
+@broker.task
+async def healthcheck_ping():
+    """TaskIQ health check task"""
+    return {"status": "healthy", "timestamp": datetime.now()}
+```
+
+### Metrics Collection
+- Task execution times
+- Success/failure rates
+- Queue depths
+- Worker utilization
+
+## Key Implementation Points - MUST READ
+
+### Critical Changes Required
+
+1. **Session Management in Tasks**
+   - ✅ **VERIFIED**: Tasks MUST use `get_session()` from `reflector.db` for test compatibility
+   - ❌ Do NOT use `get_session_factory()` directly in tasks - it bypasses test mocks
+   - ✅ The test database session IS properly shared when using `get_session()`
+
+2. **Task Invocation Changes**
+   - Replace `.delay()` with `await .kiq()`
+   - All task invocations become async/await
+   - No need to commit sessions before task invocation (controllers handle this)
+
+3. **Broker Configuration**
+   - TaskIQ broker must be initialized in `worker/app.py`
+   - Use `InMemoryBroker(await_inplace=True)` for testing
+   - Use `RedisStreamBroker` for production
+
+4. **Test Setup Requirements**
+   - Set `os.environ["ENVIRONMENT"] = "pytest"` at top of test files
+   - Add TaskIQ broker fixture to test functions
+   - Keep Celery fixtures for now (dual-mode operation)
+
+5. **Import Pattern Changes**
+   ```python
+   # Each file needs both imports during migration
+   from reflector.pipelines.main_file_pipeline import (
+       task_pipeline_file_process,        # Celery version
+       task_pipeline_file_process_taskiq, # TaskIQ version
+   )
+   ```
+
+6. **Decorator Changes**
+   - Remove `@asynctask` - TaskIQ is async-native
+   - **Keep `@with_session`** - it works with TaskIQ tasks!
+   - Remove `@shared_task` from TaskIQ version
+   - Keep `@shared_task` on Celery version for backward compatibility
+
+## Verified POC Results
+
+✅ **Database transactions work correctly** across test and TaskIQ tasks
+✅ **Tasks execute immediately** in tests with `InMemoryBroker(await_inplace=True)`
+✅ **Session mocking works** when using `get_session()` properly
+✅ **"OK" output confirmed** - TaskIQ task executes and accesses test data
+
+## Conclusion
+
+The migration from Celery to TaskIQ is feasible and offers several advantages for an async-first codebase like Reflector. The key challenges will be:
+
+1. Migrating complex pipeline patterns (chain/chord)
+2. Ensuring scheduled task reliability
+3. **SOLVED**: Maintaining session management patterns - use `get_session()`
+4. Updating the test suite
+
+The phased approach allows for gradual migration with minimal risk. The ability to run both systems in parallel provides a safety net during the transition period.

+ICS Calendar Synchronization Service
+
+This module provides services for fetching, parsing, and synchronizing ICS (iCalendar)
+calendar feeds with room booking data in the database.
+
+Key Components:
+- ICSFetchService: Handles HTTP fetching and parsing of ICS calendar data
+- ICSSyncService: Manages the synchronization process between ICS feeds and database
+
+Example Usage:
+    # Sync a room's calendar
+    room = Room(id="room1", name="conference-room", ics_url="https://cal.example.com/room.ics")
+    result = await ics_sync_service.sync_room_calendar(room)
+
+    # Result structure:
+    {
+        "status": "success",  # success|unchanged|error|skipped
+        "hash": "abc123...",  # MD5 hash of ICS content
+        "events_found": 5,    # Events matching this room
+        "total_events": 12,   # Total events in calendar within time window
+        "events_created": 2,  # New events added to database
+        "events_updated": 3,  # Existing events modified
+        "events_deleted": 1   # Events soft-deleted (no longer in calendar)
+    }
+
+Event Matching:
+    Events are matched to rooms by checking if the room's full URL appears in the
+    event's LOCATION or DESCRIPTION fields. Only events within a 25-hour window
+    (1 hour ago to 24 hours from now) are processed.
+
+Input: ICS calendar URL (e.g., "https://calendar.google.com/calendar/ical/...")
+Output: EventData objects with structured calendar information:
+    {
+        "ics_uid": "event123@google.com",
+        "title": "Team Meeting",
+        "description": "Weekly sync meeting",

+### 1.1 Create TaskIQ Broker Configuration
+- [ ] Create `reflector/worker/taskiq_broker.py` with broker setup
+- [ ] Configure Redis broker with proper connection pooling
+- [ ] Add retry middleware for 1:1 parity with Celery
+- [ ] Setup test/production environment detection
+
+### 1.2 Session Management Utilities
+- [ ] Create `get_session_context()` function in `reflector/db.py`
+- [ ] Ensure `@with_session` decorator works with TaskIQ
+- [ ] Verify test mocking works with new session approach
+
+## Phase 2: Simple Task Migration (Start Small)
+
+### 2.1 Migrate Single Tasks First
+- [ ] `reflector/worker/cleanup.py` - 1 task, simple logic
+- [ ] `reflector/worker/webhook.py` - 1 task with retry logic
+- [ ] Test each migrated task individually
+
+### 2.2 Create Dual-Mode Tasks
+- [ ] Keep Celery version with `@shared_task`
+- [ ] Add TaskIQ version without `@asynctask`
+- [ ] Use feature flag to switch between versions
+
+## Phase 3: Complex Pipeline Migration
+
+### 3.1 File Processing Pipeline
+- [ ] Migrate `task_pipeline_file_process` completely
+- [ ] Handle all sub-tasks in the pipeline
+- [ ] Migrate chain/group/chord patterns to TaskIQ
+
+### 3.2 Live Processing Pipeline
+- [ ] Migrate all 10 tasks in `main_live_pipeline.py`
+- [ ] Convert complex chord patterns
+- [ ] Ensure WebSocket notifications still work
+
+## Phase 4: Scheduled Tasks Migration
+
+### 4.1 Convert Celery Beat to TaskIQ Scheduler
+- [ ] Create `reflector/worker/scheduler.py`
+- [ ] Migrate all scheduled tasks
+- [ ] Setup TaskIQ scheduler service
+
+## Phase 5: Testing Infrastructure
+
+### 5.1 Update Test Fixtures
+- [ ] Create TaskIQ test fixtures in `conftest.py`
+- [ ] Ensure dual-mode testing (both Celery and TaskIQ)
+- [ ] Verify all existing tests pass
+
+### 5.2 Migration-Specific Tests
+- [ ] Test session management across tasks
+- [ ] Test retry logic parity
+- [ ] Test scheduled task execution
+
+## Phase 6: Deployment & Monitoring
+
+### 6.1 Update Deployment Scripts
+- [ ] Update Docker configurations
+- [ ] Create TaskIQ worker startup scripts
+- [ ] Setup health checks for TaskIQ
+
+### 6.2 Monitoring Setup
+- [ ] Create TaskIQ metrics collection
+- [ ] Setup alerting for failed tasks
+- [ ] Create migration rollback plan
+
+## Execution Order
+
+1. **Week 1**: Phase 1 + Phase 2.1
+2. **Week 2**: Phase 2.2 + Phase 3.1
+3. **Week 3**: Phase 3.2 + Phase 4
+4. **Week 4**: Phase 5
+5. **Week 5**: Phase 6 + Testing
+6. **Week 6**: Cutover + Monitoring
+
+## Success Metrics
+
+- All tests passing with TaskIQ
+- No performance degradation
+- Successful parallel running for 1 week
+- Zero data loss during migration
+- Rollback tested and documented
