-# BitTorrent Protocol Implementation
-
-## Core Protocols (BEP 3, 5)
-
-**Base Protocol**: 68-byte handshake (protocol string, reserved bytes, 20-byte info hash, 20-byte peer ID). Message types: keep-alive, choke, unchoke, interested, not interested, have, bitfield, request, piece, cancel, port. SHA-1 hashing for v1 (BEP 3). See [`ccbt/protocols/bittorrent.py`](mdc:ccbt/protocols/bittorrent.py).
-
-**Protocol v2 (BEP 52)**: SHA-256 hashing, 32-byte info hash, Merkle tree structure, hybrid support. See [`ccbt/protocols/bittorrent_v2.py`](mdc:ccbt/protocols/bittorrent_v2.py), [`ccbt/core/torrent_v2.py`](mdc:ccbt/core/torrent_v2.py).
-
-## Discovery Protocols
-
-**DHT (BEP 5)**: Kademlia algorithm in [`ccbt/discovery/dht.py`](mdc:ccbt/discovery/dht.py). IPv6 support (BEP 32), read-only mode (BEP 43), storage (BEP 44), multi-address (BEP 45), indexing (BEP 51). Private torrents (BEP 27) disable DHT.
-
-**Trackers**: HTTP/UDP trackers in [`ccbt/discovery/tracker.py`](mdc:ccbt/discovery/tracker.py), UDP client (BEP 15) in [`ccbt/discovery/tracker_udp_client.py`](mdc:ccbt/discovery/tracker_udp_client.py). Scrape support (BEP 48). Tiered announce lists (BEP 12).
-
-**PEX (BEP 11)**: Peer exchange in [`ccbt/extensions/pex.py`](mdc:ccbt/extensions/pex.py), [`ccbt/discovery/pex.py`](mdc:ccbt/discovery/pex.py). Disabled for private torrents (BEP 27).
-
-**Magnet Links (BEP 9)**: Parsing in [`ccbt/core/magnet.py`](mdc:ccbt/core/magnet.py). File selection (BEP 53) via `so` and `x.pe` parameters.
-
-## Extension Protocol (BEP 10)
-
-**Extension Manager**: [`ccbt/extensions/manager.py`](mdc:ccbt/extensions/manager.py) coordinates all extensions. Handshake negotiation in [`ccbt/extensions/protocol.py`](mdc:ccbt/extensions/protocol.py).
-
-**Fast Extension (BEP 6)**: [`ccbt/extensions/fast.py`](mdc:ccbt/extensions/fast.py) - suggest piece, have all/none, reject request, allow fast.
-
-**Compact Peer Lists (BEP 23)**: IPv4 (6 bytes), IPv6 (18 bytes) in [`ccbt/extensions/compact.py`](mdc:ccbt/extensions/compact.py).
-
-**WebSeed (BEP 19)**: HTTP range requests in [`ccbt/extensions/webseed.py`](mdc:ccbt/extensions/webseed.py).
-
-**SSL/TLS**: Peer/tracker encryption in [`ccbt/extensions/ssl.py`](mdc:ccbt/extensions/ssl.py).
-
-**XET Extension**: Content-defined chunking, deduplication, P2P CAS. See [`ccbt/extensions/xet.py`](mdc:ccbt/extensions/xet.py), [`docs/bep_xet.md`](mdc:docs/bep_xet.md).
-
-## File Attributes (BEP 47)
-
-**Preservation**: Symlinks, executable bits, hidden files. SHA-1 file verification. Padding file skipping. See [`ccbt/piece/async_piece_manager.py`](mdc:ccbt/piece/async_piece_manager.py) checkpoint handling.
-
-## Private Torrents (BEP 27)
-
-**Enforcement**: DHT, PEX, LSD disabled. Only tracker-provided peers accepted. Detection in [`ccbt/session/torrent_utils.py`](mdc:ccbt/session/torrent_utils.py), validation in [`ccbt/peer/async_peer_connection.py`](mdc:ccbt/peer/async_peer_connection.py).
-
-## Transport Protocols
-
-**uTP (BEP 29)**: uTorrent Transport Protocol for congestion control. See [`ccbt/transport/`](mdc:ccbt/transport/).
-
-**WebTorrent**: WebRTC data channels, WebSocket trackers in [`ccbt/protocols/webtorrent.py`](mdc:ccbt/protocols/webtorrent.py).
-
-## Implementation Patterns
-
-### Session Delegation
-
-Session orchestrates via [`ccbt/session/session.py`](mdc:ccbt/session/session.py), delegates to controllers:
-- **Announce**: [`ccbt/session/announce.py`](mdc:ccbt/session/announce.py) - tracker announces
-- **Checkpointing**: [`ccbt/session/checkpointing.py`](mdc:ccbt/session/checkpointing.py) - state persistence
-- **Download Startup**: [`ccbt/session/download_startup.py`](mdc:ccbt/session/download_startup.py) - initialization
-- **Torrent Addition**: [`ccbt/session/torrent_addition.py`](mdc:ccbt/session/torrent_addition.py) - torrent/magnet handling
-
-### Message Handling
-
-Peer connections in [`ccbt/peer/async_peer_connection.py`](mdc:ccbt/peer/async_peer_connection.py). Extension messages (BEP 10) handled via `handle_extension_message()`. v2 messages (BEP 52) via `handle_v2_message()`.
-
-### Piece Management
-
-Piece manager in [`ccbt/piece/async_piece_manager.py`](mdc:ccbt/piece/async_piece_manager.py). Supports v1/v2/hybrid (BEP 52). Metadata exchange (BEP 10 + ut_metadata) in [`ccbt/piece/async_metadata_exchange.py`](mdc:ccbt/piece/async_metadata_exchange.py).
-
-### Error Handling
-
-**Timeouts**: All async operations use `asyncio.wait_for()` with configurable timeouts. See session startup patterns.
-
-**Protocol Violations**: Invalid messages logged and connection closed gracefully.
-
-**Retry Logic**: Exponential backoff for tracker announces, DHT queries. See [`ccbt/discovery/tracker.py`](mdc:ccbt/discovery/tracker.py).

-# ccBitTorrent Development Patterns (uv + dev)
-
-## Tooling & Configuration
-- **All configs in `dev/`**: [`dev/ruff.toml`](mdc:dev/ruff.toml), [`dev/ty.toml`](mdc:dev/ty.toml), [`dev/pytest.ini`](mdc:dev/pytest.ini), [`dev/mkdocs.yml`](mdc:dev/mkdocs.yml), [`dev/pre-commit-config.yaml`](mdc:dev/pre-commit-config.yaml), [`dev/.codecov.yml`](mdc:dev/.codecov.yml)
-- **Use `uv` for all commands** - No Makefile. Install pre-commit: `uv run pre-commit install --config dev/pre-commit-config.yaml` (also `--hook-type commit-msg`)
-
-## Standard Commands
-- **Lint**: `uv run ruff --config dev/ruff.toml check ccbt/ --fix --exit-non-zero-on-fix`
-- **Format**: `uv run ruff --config dev/ruff.toml format ccbt/`
-- **Types**: `uv run ty check --config-file=dev/ty.toml --output-format=concise`
-- **Tests**: `uv run pytest -c dev/pytest.ini tests/ -v --tb=short --maxfail=5 --timeout=60`
-- **Coverage**: `uv run pytest -c dev/pytest.ini tests/ --cov=ccbt --cov-report=term-missing --cov-report=xml --cov-report=html`
-- **Security**: `uv run bandit -r ccbt/ -f json -o docs/reports/bandit/bandit-report.json --severity-level medium -x tests,benchmarks,dev,dist,docs,htmlcov,site,.venv,.pre-commit-cache,.pre-commit-home,.pytest_cache,.ruff_cache,.hypothesis,.github,.ccbt,.cursor,.benchmarks`
-- **Docs**: `uv run mkdocs build --strict -f dev/mkdocs.yml`
-
-## Selective Testing
-- Use [`tests/scripts/run_pytest_selective.py`](mdc:tests/scripts/run_pytest_selective.py) with [`tests/scripts/get_test_markers.py`](mdc:tests/scripts/get_test_markers.py)
-- Critical files trigger full suite: `dev/pytest.ini`, `dev/pre-commit-config.yaml`, `dev/.codecov.yml`, `tests/conftest.py`, `ccbt/config/config.py`
-
-## Reports in Docs
-- Coverage HTML: `docs/reports/coverage/` (linked in nav)
-- Bandit JSON: `docs/reports/bandit/bandit-report.json` (rendered by [`docs/reports/bandit/index.md`](mdc:docs/reports/bandit/index.md))
-
-## Architecture & Separation of Concerns
-
-### Module Boundaries
-- **CLI (`ccbt/cli/`)**: Command definitions, orchestration, UI output. Delegates to session.
-- **Session (`ccbt/session/`)**: Torrent lifecycle, component coordination. Delegates to specialized controllers.
-- **Core (`ccbt/core/`, `ccbt/peer/`, `ccbt/piece/`, `ccbt/storage/`)**: Domain logic, no CLI/session dependencies.
-- **Orchestration modules**: [`ccbt/cli/downloads.py`](mdc:ccbt/cli/downloads.py), [`ccbt/cli/status.py`](mdc:ccbt/cli/status.py), [`ccbt/cli/resume.py`](mdc:ccbt/cli/resume.py) bridge CLI→Session.
-
-### Session Delegation Pattern
-- `AsyncTorrentSession` orchestrates; delegates to controllers:
-  - [`ccbt/session/lifecycle.py`](mdc:ccbt/session/lifecycle.py): Lifecycle sequencing (start/pause/resume/stop/cancel)
-  - [`ccbt/session/checkpointing.py`](mdc:ccbt/session/checkpointing.py): Checkpoint operations with fast resume support
-  - [`ccbt/session/status_aggregation.py`](mdc:ccbt/session/status_aggregation.py): Status collection and aggregation
-  - [`ccbt/session/announce.py`](mdc:ccbt/session/announce.py): Tracker announces (AnnounceLoop, AnnounceController)
-  - [`ccbt/session/metrics_status.py`](mdc:ccbt/session/metrics_status.py): Status monitoring loop (StatusLoop)
-  - [`ccbt/session/peers.py`](mdc:ccbt/session/peers.py): Peer management (PeerManagerInitializer, PeerConnectionHelper, PexBinder)
-  - [`ccbt/session/peer_events.py`](mdc:ccbt/session/peer_events.py): Peer event binding (PeerEventsBinder)
-  - [`ccbt/session/magnet_handling.py`](mdc:ccbt/session/magnet_handling.py): Magnet file selection (MagnetHandler)
-  - [`ccbt/session/dht_setup.py`](mdc:ccbt/session/dht_setup.py): DHT discovery setup (DiscoveryController)
-  - [`ccbt/session/download_startup.py`](mdc:ccbt/session/download_startup.py): Download initialization
-- `AsyncSessionManager` orchestrates; delegates to managers:
-  - [`ccbt/session/torrent_addition.py`](mdc:ccbt/session/torrent_addition.py): Torrent addition flow (TorrentAdditionHandler)
-  - [`ccbt/session/manager_background.py`](mdc:ccbt/session/manager_background.py): Background tasks (ManagerBackgroundTasks)
-  - [`ccbt/session/scrape.py`](mdc:ccbt/session/scrape.py): Tracker scraping (ScrapeManager)
-  - [`ccbt/session/checkpoint_operations.py`](mdc:ccbt/session/checkpoint_operations.py): Manager-level checkpoint operations (CheckpointOperations)
-  - [`ccbt/session/manager_startup.py`](mdc:ccbt/session/manager_startup.py): Component startup sequence
-
-### Dependency Injection
-- Optional DI via [`ccbt/utils/di.py`](mdc:ccbt/utils/di.py): `DIContainer` for factories (security, DHT, NAT, TCP server)
-- Falls back to concrete classes when DI not provided
-- Use `ComponentFactory` for component creation
-
-## Type Safety & Code Quality
-
-### Type Hints
-- **All functions require type hints** - Use `typing` module, `from __future__ import annotations`
-- **Pydantic models** - Use `BaseModel` for validation, not dataclasses
-- **Async functions** - `async def` for all I/O operations
-- **Return types** - Always specify, use `-> None` for void functions
-
-### Async/Await Patterns
-- **Always await async functions** - Never call async functions without `await`. Calling without await returns a coroutine object, not the result, causing race conditions and bugs.
-- **Correct**: `result = await async_function()`
-- **Incorrect**: `result = async_function()` then checking `if asyncio.iscoroutine(result)`
-- **Singleton async functions** - If a function returns a singleton (like `get_udp_tracker_client()`), always await it directly. Multiple concurrent calls without await can create multiple instances, causing resource conflicts.
-- **Error handling** - Use `try/except` around awaited calls. Use `asyncio.wait_for()` for timeouts.
-
-### Error Handling
-- **Custom exceptions** from [`ccbt/utils/exceptions.py`](mdc:ccbt/utils/exceptions.py)
-- **Timeout patterns** - Use `asyncio.wait_for()` with timeouts for blocking operations
-- **Graceful degradation** - Log warnings, continue when non-critical components fail
-
-### Configuration
-- **Pydantic models** in [`ccbt/config/config.py`](mdc:ccbt/config/config.py) for validation
-- **CLI overrides** via [`ccbt/cli/overrides.py`](mdc:ccbt/cli/overrides.py): `apply_cli_overrides(config_manager, kwargs)`
-- **Environment variables** with `CCBT_` prefix
-
-## Performance & Security
-
-### Performance
-- **Zero-copy operations** where possible
-- **Memory pools** for frequent allocations
-- **Ring buffers** for high-throughput operations
-- **SIMD-accelerated** hash verification
-- **Async I/O** - All disk/network operations are async
-
-### Security
-- **Input validation** via Pydantic models
-- **Rate limiting** for external interactions
-- **Peer validation** before connections
-- **Encryption support** for sensitive data
-- **IP filtering** via [`ccbt/security/security_manager.py`](mdc:ccbt/security/security_manager.py)
-
-### Windows Path Resolution
-- **CRITICAL**: Use `_get_daemon_home_dir()` helper from `ccbt/daemon/daemon_manager.py` for all daemon-related paths
-- **Why**: Windows can resolve `Path.home()` or `os.path.expanduser("~")` differently in different processes, especially with spaces in usernames
-- **Pattern**: Helper tries multiple methods (`expanduser`, `USERPROFILE`, `HOME`, `Path.home()`) and uses `Path.resolve()` for canonical path
-- **Usage**: Always use helper instead of direct `Path.home()` or `os.path.expanduser("~")` for daemon PID files, state directories, config files
-- **Files affected**: `DaemonManager`, `StateManager`, `IPCClient`, any code that reads/writes daemon PID file or state
-- **Result**: Ensures daemon and CLI use same canonical path, preventing detection failures
-
-## Testing Patterns
-- **Markers**: Use pytest markers (`@pytest.mark.unit`, `@pytest.mark.integration`, etc.) defined in [`dev/pytest.ini`](mdc:dev/pytest.ini)
-- **Coverage target**: 99% project-wide, 90% patch (see [`dev/.codecov.yml`](mdc:dev/.codecov.yml))
-- **Selective runs**: Test only affected modules via selective test runner
-- **Mock patterns**: Handle `AttributeError`/`TypeError` gracefully for test mocks
-- **Pragma comments**: Use `# pragma: no cover` for UI-only paths, defensive error handlers

-## Implementation Patterns
-
-### Metrics Recording
-```python
-from ccbt.monitoring import MetricsCollector
-
-metrics = MetricsCollector()
-metrics.record_metric("download_speed", 1024*1024)
-metrics.set_gauge("peer_count", len(peers))
-metrics.increment_counter("pieces_completed")
-```
-
-### Alert Rules

-
-alert_manager = AlertManager()
-alert_manager.add_alert_rule(
-    name="high_cpu",
-    metric_name="system_cpu_usage",
-    condition="value > 80",
-    severity="warning"
-)
-```
-
-### Tracing
-```python
-from ccbt.monitoring import TracingManager
-
-tracing = TracingManager()
-span_id = tracing.start_span("download_piece", SpanKind.INTERNAL)
-# ... do work ...
-tracing.end_span(span_id, SpanStatus.OK)
-```
-
-### Profiling
-```python
-from ccbt.observability import Profiler
-
-profiler = Profiler()
-profiler.start()
-
-@profiler.profile_function("download_piece")
-async def download_piece(piece_index: int):
-    # ... implementation ...
-```
-
-## IPC Integration
-
-**Metrics Endpoints**: IPC server exposes metrics via REST API:
-- `GET /api/v1/metrics/peers` - Global peer metrics across all torrents
-- `GET /api/v1/metrics/peers/{peer_key}` - Detailed metrics for specific peer
-- `GET /api/v1/metrics/torrents/{info_hash}/detailed` - Detailed torrent metrics
-- `GET /api/v1/metrics/global/detailed` - Detailed global metrics including connection success rate
-- `GET /api/v1/peers/list` - Global list of all peers with comprehensive metrics
-
-**Metrics Exposure**: All enhanced metrics (peer performance, efficiency, connection quality, swarm health) are exposed via IPC endpoints for client monitoring and analysis.
-
-## Event Integration
-All monitoring components emit events for integration:
-- `MONITORING_STARTED` - Monitoring system started
-- `ALERT_TRIGGERED` - Alert condition met
-- `SPAN_STARTED` - Tracing span started
-- `BOTTLENECK_DETECTED` - Performance bottleneck identified

----
-
-# Performance Optimization Patterns
-
-## Zero-Copy Operations
-Located in [ccbt/buffers.py](mdc:ccbt/buffers.py):
-
-### Ring Buffers
-- **High-Throughput**: Ring buffers for zero-copy data transfer
-- **Memory Pools**: Pre-allocated memory pools for frequent allocations
-- **Buffer Management**: Efficient buffer lifecycle management
-
-```python
-class RingBuffer:
-    def __init__(self, size: int):
-        self.buffer = bytearray(size)
-        self.head = 0
-        self.tail = 0
-    
-    def write(self, data: bytes) -> int:
-        # Zero-copy write operation
-        pass
-```
-
-## Network I/O Optimization
-Located in [ccbt/network_optimizer.py](mdc:ccbt/network_optimizer.py):
-
-### Socket Tuning
-- **TCP_NODELAY**: Disable Nagle's algorithm for low latency
-- **SO_REUSEPORT**: Enable port reuse for load balancing
-- **Buffer Sizing**: Optimize socket buffer sizes based on BDP
-- **Connection Pooling**: Reuse connections for efficiency
-
-### Adaptive Connection Limits
-Located in [ccbt/peer/connection_pool.py](mdc:ccbt/peer/connection_pool.py):
-- **Adaptive Limit Calculation**: `_calculate_adaptive_limit()` dynamically adjusts max connections based on:
-  - CPU usage (reduce if > threshold, default 80%)
-  - Memory usage (reduce if > threshold, default 80%)
-  - Peer performance (increase if peers performing well)
-  - Formula: `base_limit * cpu_factor * memory_factor * performance_factor`
-  - Bounded by `connection_pool_adaptive_limit_min` and `connection_pool_adaptive_limit_max`
-- **Performance-Based Recycling**: Low-performing connections are recycled when:
-  - Performance score < threshold (default 0.3)
-  - Consecutive failures > max (default 5)
-  - Idle time > max_idle_time (default 300s) AND new peer available
-  - Bandwidth below minimum thresholds
-- **Bandwidth Measurement**: Tracks download/upload bandwidth per connection with periodic updates (default 5s interval)
-- **Progressive Health Degradation**: Connection health levels (HEALTHY, DEGRADED, UNHEALTHY) based on idle time, usage, errors, and bandwidth
-- **Connection Quality Scoring**: `_calculate_connection_quality()` scores connections (0.0-1.0) based on bandwidth, latency, and error rate. Used to prefer high-quality connections in `acquire()`.
-
-```python
-class NetworkOptimizer:
-    def optimize_socket(self, sock: socket.socket) -> None:
-        sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
-        sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
-```
-
-## Disk I/O Enhancement
-Located in [ccbt/disk_io.py](mdc:ccbt/disk_io.py):
-
-### io_uring Support (Linux)
-- **Asynchronous I/O**: Use io_uring for high-performance I/O
-- **Batch Operations**: Batch multiple I/O operations
-- **Zero-Copy I/O**: Direct memory access for large transfers
-
-### AIO Fallback
-- **Cross-Platform**: AIO fallback for non-Linux systems
-- **Async I/O**: Asynchronous file operations
-- **Error Handling**: Proper error handling for I/O operations
-
-### NVMe Optimizations
-- **Direct I/O**: Bypass page cache for large sequential writes
-- **Write-Behind Caching**: Optimize write performance
-- **SSD Detection**: Detect SSD storage for optimization
-
-```python
-class DiskIO:
-    async def write_piece(self, piece_data: bytes, offset: int) -> None:
-        if self.use_io_uring:
-            await self._io_uring_write(piece_data, offset)
-        else:
-            await self._aio_write(piece_data, offset)
-```
-
-## Hash Verification Optimization
-Located in [ccbt/async_piece_manager.py](mdc:ccbt/async_piece_manager.py):
-
-### SIMD-Accelerated SHA-1
-- **OpenSSL Integration**: Use OpenSSL for SIMD-accelerated hashing
-- **Batch Verification**: Verify multiple pieces simultaneously
-- **Hash Caching**: Cache partial piece hashes
-
-```python
-class HashVerifier:
-    def verify_piece(self, piece_data: bytes, expected_hash: bytes) -> bool:
-        # SIMD-accelerated SHA-1 verification
-        actual_hash = hashlib.sha1(piece_data).digest()
-        return actual_hash == expected_hash
-```
-
-## Memory Optimization
-
-### Memory Pools
-- **Pre-allocation**: Pre-allocate memory pools for frequent operations
-- **Object Reuse**: Reuse objects to reduce garbage collection
-- **Memory Mapping**: Use memory mapping for large files
-
-### Garbage Collection
-- **Generational GC**: Optimize for generational garbage collection
-- **Weak References**: Use weak references where appropriate
-- **Memory Profiling**: Profile memory usage for optimization
-
-## Adaptive Algorithms
-
-### Adaptive Intervals
-- **DHT Adaptive Intervals**: Located in [ccbt/discovery/dht.py](mdc:ccbt/discovery/dht.py). `_calculate_adaptive_interval()` adjusts DHT refresh intervals based on:
-  - Base interval from config
-  - Node quality and reachability
-  - Network conditions
-  - Bounded by `dht_adaptive_interval_min` and `dht_adaptive_interval_max`
-- **Tracker Adaptive Intervals**: Located in [ccbt/discovery/tracker.py](mdc:ccbt/discovery/tracker.py). `_calculate_adaptive_interval()` adjusts announce intervals based on:
-  - Tracker performance (response time, success rate)
-  - Peer count from tracker
-  - Swarm health
-  - Bounded by `tracker_adaptive_interval_min` and `tracker_adaptive_interval_max`
-- **Tracker Performance Ranking**: `rank_trackers()` sorts trackers by performance score considering:
-  - Response time (lower = better)
-  - Success rate (higher = better)
-  - Peer quality (average peer download rate)
-  - Recent failures
-
-### Bandwidth-Aware Optimizations
-- **Request Prioritization**: Located in [ccbt/peer/async_peer_connection.py](mdc:ccbt/peer/async_peer_connection.py). `_calculate_request_priority()` incorporates peer download rate into priority calculation. `RequestInfo.bandwidth_estimate` stores estimated bandwidth for load balancing.
-- **Request Load Balancing**: `_balance_requests_across_peers()` distributes requests proportionally based on peer bandwidth:
-  - Calculates total available bandwidth
-  - Distributes requests proportionally to each peer's share
-  - Considers peer pipeline capacity
-  - Handles edge cases gracefully
-- **Bandwidth-Weighted Piece Selection**: Located in [ccbt/piece/async_piece_manager.py](mdc:ccbt/piece/async_piece_manager.py). Piece selection strategies consider peer download speeds when scoring pieces.
-
-### Performance-Based Peer Management
-- **Peer Ranking**: `_rank_peers_for_connection()` ranks peers before connection based on historical performance, reputation, connection success rate, and source quality.
-- **Peer Performance Evaluation**: `_evaluate_peer_performance()` calculates performance scores (0.0-1.0) from download rate, upload rate, latency, error rate, and connection stability.
-- **Peer Recycling**: Low-performing peers are automatically recycled when better peers are available, improving overall swarm efficiency.
-
-## Performance Targets
-- **50% improvement** in download speed
-- **30% reduction** in memory usage
-- **40% improvement** in disk I/O throughput
-- **Sub-100ms** peer connection establishment
-- **Adaptive algorithms** dynamically optimize based on real-time conditions
-
-## Benchmarking
-- **Performance Tests**: Regular performance regression testing
-- **Load Testing**: High-load scenario testing
-- **Memory Profiling**: Memory usage analysis
-- **CPU Profiling**: CPU usage optimization

-## Import Patterns
-
-### Textual Import Handling
-
-Always use TYPE_CHECKING blocks and fallback classes for Textual imports:
-
-```python
-from __future__ import annotations
-
-from typing import TYPE_CHECKING, Any, ClassVar
-
-if TYPE_CHECKING:
-    from textual.app import App, ComposeResult
-    from textual.screen import Screen
-    from textual.widgets import Static, DataTable
-else:
-    try:
-        from textual.app import App, ComposeResult
-        from textual.screen import Screen
-        from textual.widgets import Static, DataTable
-    except ImportError:
-        # Fallback classes for when textual is not available
-        class App:  # type: ignore[misc]
-            """Fallback App class when textual is not available."""
-        
-        class Screen:  # type: ignore[no-redef]
-            """Fallback Screen class."""
-        
-        class Static:  # type: ignore[no-redef]
-            """Fallback Static widget."""
-        
-        ComposeResult = None  # type: ignore[assignment, misc]
-```
-
-### Container Imports
-
-For containers, handle the fallback case:
-
-```python
-try:
-    from textual.containers import Container, Horizontal, Vertical
-except ImportError:
-    from typing import Any as ComposeResult
-    Container = None  # type: ignore[assignment, misc]
-    Horizontal = None  # type: ignore[assignment, misc]
-    Vertical = None  # type: ignore[assignment, misc]
-```
-
-## Screen Implementation
-
-### Base Screen Pattern
-
-All screens should inherit from base classes in [ccbt/interface/screens/base.py](mdc:ccbt/interface/screens/base.py):
-
-- **MonitoringScreen**: For monitoring/metrics screens
-- **ConfigScreen**: For configuration screens
-- **Screen**: For utility screens
-
-Example monitoring screen:
-
-```python
-from ccbt.interface.screens.base import MonitoringScreen
-
-class SystemResourcesScreen(MonitoringScreen):  # type: ignore[misc]
-    """Screen to display system resource usage."""
-    
-    CSS = """
-    #content {
-        height: 1fr;
-        overflow-y: auto;
-    }
-    """
-    
-    def compose(self) -> ComposeResult:  # pragma: no cover
-        """Compose the screen."""
-        yield Header()
-        with Vertical():
-            yield Static(id="content")
-        yield Footer()
-    
-    async def _refresh_data(self) -> None:  # pragma: no cover
-        """Refresh screen data."""
-        content = self.query_one("#content", Static)
-        # Update content...
-```
-
-### CSS Patterns
-
-- Define CSS as class variable `CSS` (string)
-- Use `#id` selectors for specific widgets
-- Use layout containers: `height: 1fr` for flexible sizing
-- Use `overflow-y: auto` for scrollable content
-- Reference Textual design tokens: `$primary`, `$surface`, etc.
-
-### Compose Pattern
-
-Always use the `compose()` method with `yield`:
-
-```python
-def compose(self) -> ComposeResult:  # pragma: no cover
-    """Compose the screen."""
-    yield Header()
-    with Vertical():
-        yield Static(id="content")
-        yield DataTable(id="table")
-    yield Footer()
-```
-
-### Event Handling
-
-- Use `on_mount()` for initialization
-- Use `on_unmount()` for cleanup
-- Use `action_*` methods for keyboard bindings
-- Use `on_*` methods for widget events (e.g., `on_button_pressed`)
-
-### Bindings
-
-Define keyboard bindings as class variable:
-
-```python
-BINDINGS: ClassVar[list[tuple[str, str, str]]] = [
-    ("escape", "back", "Back"),
-    ("q", "quit", "Quit"),
-    ("r", "refresh", "Refresh"),
-]
-```
-
-## Widget Implementation
-
-### Widget Base Classes
-
-Widgets extend Textual widgets (usually `Static`):
-
-```python
-from textual.widgets import Static
-
-class Overview(Static):  # type: ignore[misc]
-    """Simple widget to render global stats."""
-    
-    def update_from_stats(self, stats: dict[str, Any]) -> None:
-        """Update widget with statistics."""
-        # Use Rich for formatting
-        from rich.table import Table
-        from rich.panel import Panel
-        
-        table = Table()
-        # Build table...
-        self.update(Panel(table, title="Overview"))
-```
-
-### Widget Patterns
-
-- Use `update()` method to change widget content
-- Use Rich library for formatting (Table, Panel, etc.)
-- Use Rich `Text` for colored segments and complex formatting
-- Keep widgets focused on single responsibility
-- Export widgets through `widgets/__init__.py`
-- **Always wrap user-facing strings** with `_()` for i18n
-
-### Health Bar Widgets
-
-For health monitoring widgets (e.g., piece availability), use colored segments:
-
-```python
-from textual.widgets import Static
-from rich.text import Text
-from ccbt.i18n import _
-
-class PieceAvailabilityHealthBar(Static):  # type: ignore[misc]
-    """Widget to display piece availability as a colored health bar."""
-    
-    DEFAULT_CSS = """
-    PieceAvailabilityHealthBar {
-        height: 1;
-        width: 1fr;
-    }
-    """
-    
-    def update_availability(self, availability: list[int], max_peers: int | None = None) -> None:
-        """Update health bar with piece availability data."""
-        # Build colored bar with thin segments
-        bar_text = Text()
-        for peer_count in availability:
-            color = self._get_color_for_availability(peer_count)
-            bar_text.append("▌", style=color)  # Thin bar character
-        
-        # Add summary label
-        label = Text()
-        label.append(f" {_('Health')}: ", style="cyan")
-        label.append(f"{availability_pct:.1f}%", style="green")
-        
-        full_text = Text()
-        full_text.append(bar_text)
-        full_text.append(" ")
-        full_text.append(label)
-        self.update(full_text)
-```
-
-### Color Coding Patterns
-
-- **Green**: High availability/health (≥70% or high value)
-- **Yellow**: Medium availability/health (40-70%)
-- **Orange**: Low availability/health (20-40%)
-- **Red**: Very low availability/health (<20% or critical)
-- **Gray**: Not available or no data
-
-## Configuration Screens
-
-Configuration screens inherit from `ConfigScreen`:
-
-```python
-from ccbt.interface.screens.base import ConfigScreen
-
-class SSLConfigScreen(ConfigScreen):  # type: ignore[misc]
-    """Screen to manage SSL/TLS configuration."""
-    
-    CSS = """..."""
-    BINDINGS: ClassVar[list[tuple[str, str, str]]] = [...]
-    
-    def compose(self) -> ComposeResult:
-        """Compose configuration screen."""
-        # Use ConfigValueEditor and ConfigSectionWidget from
-        # ccbt/interface/screens/config/widgets.py
-```
-
-## Data Access Pattern
-
-**CRITICAL**: The interface must use `DataProvider` for all read operations and `CommandExecutor` for all write operations. Never access session internals directly.
-
-### DataProvider Pattern
-
-Use `DataProvider` from [ccbt/interface/data_provider.py](mdc:ccbt/interface/data_provider.py) to access torrent data:
-
-```python
-from ccbt.interface.data_provider import DataProvider
-
-class MyScreen(Screen):
-    def __init__(self, data_provider: DataProvider, *args, **kwargs):
-        super().__init__(*args, **kwargs)
-        self._data_provider = data_provider
-    
-    async def refresh_data(self):
-        """Refresh data using DataProvider."""
-        # Read operations use DataProvider
-        stats = await self._data_provider.get_global_stats()
-        torrents = await self._data_provider.list_torrents()
-        status = await self._data_provider.get_torrent_status(info_hash)
-        peers = await self._data_provider.get_torrent_peers(info_hash)
-        files = await self._data_provider.get_torrent_files(info_hash)
-        trackers = await self._data_provider.get_torrent_trackers(info_hash)
-        availability = await self._data_provider.get_torrent_piece_availability(info_hash)
-        metrics = await self._data_provider.get_metrics()
-```
-
-### CommandExecutor Pattern
-
-Use `CommandExecutor` from [ccbt/interface/commands/executor.py](mdc:ccbt/interface/commands/executor.py) for all write operations:
-
-```python
-from ccbt.interface.commands.executor import CommandExecutor
-
-class MyScreen(Screen):
-    def __init__(self, data_provider: DataProvider, command_executor: CommandExecutor, *args, **kwargs):
-        super().__init__(*args, **kwargs)
-        self._data_provider = data_provider
-        self._command_executor = command_executor
-    
-    async def action_pause_torrent(self):
-        """Pause torrent using executor."""
-        result = await self._command_executor.execute_command(
-            "torrent.pause", info_hash=info_hash
-        )
-        if result and hasattr(result, "success") and result.success:
-            self.app.notify("Torrent paused", severity="success")
-```
-
-### Daemon Access Rules
-
-- **Read operations**: Always use `DataProvider` methods (never direct IPC client calls)
-- **Write operations**: Always use `CommandExecutor.execute_command()` (never direct session calls)
-- **Never access**: `self.session` internals directly when using daemon
-- **Exception**: Local sessions can access `self.session` directly, but prefer DataProvider/Executor for consistency
-
-## Module Exports
-
-### Widgets Module
-
-Export all widgets in [ccbt/interface/widgets/__init__.py](mdc:ccbt/interface/widgets/__init__.py):
-
-```python
-from ccbt.interface.widgets.core_widgets import (
-    Overview,
-    PeersTable,
-    SpeedSparklines,
-    TorrentsTable,
-)
-from ccbt.interface.widgets.reusable_widgets import (
-    MetricsTableWidget,
-    ProgressBarWidget,
-    SparklineGroup,
-)
-
-__all__ = [
-    "MetricsTableWidget",
-    "Overview",
-    "PeersTable",
-    "ProgressBarWidget",
-    "SparklineGroup",
-    "SpeedSparklines",
-    "TorrentsTable",
-]
-```
-
-### Screens Module
-
-Export base classes in [ccbt/interface/screens/__init__.py](mdc:ccbt/interface/screens/__init__.py). Individual screens are imported directly from their modules.
-
-## Main Dashboard
-
-The main dashboard in [ccbt/interface/terminal_dashboard.py](mdc:ccbt/interface/terminal_dashboard.py) contains:
-
-- `TerminalDashboard` class (extends `App`)
-- `run_dashboard()` function
-- `main()` function (CLI entry point)
-
-All screens and widgets are imported from their respective modules.
-
-## Rich Integration
-
-Use Rich library for formatting:
-
-- `Panel`: For bordered content areas
-- `Table`: For tabular data
-- Rich markup: `[bold]`, `[cyan]`, `[green]`, etc.
-
-Example:
-
-```python
-from rich.panel import Panel
-from rich.table import Table
-
-table = Table(title="Metrics", expand=True)
-table.add_column("Metric", style="cyan", ratio=1)
-table.add_column("Value", style="green", ratio=2)
-table.add_row("CPU", "45%")
-
-content.update(Panel(table, title="System Resources"))
-```
-
-## Type Hints
-
-- Use `ComposeResult` for `compose()` return type
-- Use `TYPE_CHECKING` blocks for type-only imports
-- Use `# type: ignore[misc]` for Textual base classes
-- Use `# pragma: no cover` for UI code that's hard to test
-
-## Error Handling
-
-- Always handle Textual import failures gracefully
-- Use try/except blocks for async operations
-- Display errors in UI using Rich Panels with `border_style="red"`
-
-## Testing Considerations
-
-- Mark UI code with `# pragma: no cover`
-- Use integration tests for screen behavior
-- Mock Textual widgets in unit tests
-- Test fallback behavior when Textual is unavailable
-
-
-## i18n Integration
-
-### String Wrapping
-
-All user-facing strings must be wrapped with `_()`:
-
-```python
-from ccbt.i18n import _
-
-# In bindings
-BINDINGS: ClassVar[list[tuple[str, str, str]]] = [
-    ("p", "pause", _("Pause")),
-    ("r", "resume", _("Resume")),
-]
-
-# In notifications
-self.app.notify(_("Torrent paused"), severity="success")
-
-# In table headers
-table.add_column(_("Name"), style="cyan")
-
-# In widget labels
-label.append(f" {_('Health')}: ", style="cyan")
-```
-
-### Language Selector
-
-Use `LanguageSelectorWidget` from [ccbt/interface/widgets/language_selector.py](mdc:ccbt/interface/widgets/language_selector.py) to allow users to change interface language:
-
-```python
-from ccbt.interface.widgets.language_selector import LanguageSelectorWidget
-
-def compose(self) -> ComposeResult:
-    with Vertical():
-        yield LanguageSelectorWidget(data_provider, command_executor)
-```
-
-## Tabbed Interface Structure
-
-The interface uses a tabbed structure with nested tabs:
-
-### Main Tabs
-
-1. **Torrents Tab**: Lists all torrents with nested sub-tabs (global, downloading, seeding, completed, active, inactive)
-2. **Per-Torrent Tab**: Detailed view for selected torrent with sub-tabs (files, info, peers, trackers, graphs, config)
-3. **Graphs Tab**: Global statistics and graphs (always visible in top half)
-4. **Preferences Tab**: Configuration with nested sub-tabs
-
-### Container vs Screen
-
-- **Container widgets**: Used for tab content (e.g., `TorrentsTabContent`, `PerTorrentTabContent`)
-- **Screen classes**: Used for full-screen overlays (e.g., `AddTorrentScreen`, `ConfigScreen`)
-- **Never embed Screen in Container**: Use wrapper widgets (`MonitoringScreenWrapper`, `ConfigScreenWrapper`) to extract data from screens

 This document provides a comprehensive overview of all GitHub Actions workflows in the ccBitTorrent project.
 
+**Policy**: All testing and builds run **manually** (via `workflow_dispatch`) for anything not targeting `main`. PRs to `main` run the same checks but **require manual approval** (environment `approval-required`) before jobs execute. See [Manual approval (approval-required)](#manual-approval-approval-required).

+## Manual approval (approval-required)
+
+Workflows that run on **PR to main** use the environment **`approval-required`**. Before those jobs run, a configured reviewer must approve the run in the Actions UI.
+
+**Setup**: In the repository go to **Settings → Environments → New environment** → name it `approval-required` → enable **Required reviewers** and add the users or teams who may approve runs. Jobs that reference this environment will then wait for approval before executing.
+
+---
+
 ## Testing & Quality Assurance
 
 ### Test Workflow (test.yml)
-- **Triggers**: Push/PR to `dev` branch, `workflow_dispatch`
+- **Triggers**: PR to `main` (runs after approval), `workflow_dispatch`
 - **Purpose**: Run full test suite with coverage across multiple platforms and Python versions
 - **Runs**:
   - All tests except compatibility tests (excluded with `-m "not compatibility"`)
   - Coverage reporting (XML, HTML, terminal)
   - Test matrix: Ubuntu, Windows, macOS × Python 3.8-3.12 (reduced matrix for Windows/macOS)
 - **Rationale**:
-  - Tests run on `dev` branch (development branch), avoiding duplicate runs when merging to main
-  - Excludes compatibility tests which run separately on schedule/manual trigger
-  - Windows tests use `shell: bash` to handle line continuation correctly
+  - For branches other than `main`, run tests manually via **Actions → Test → Run workflow**
+  - PRs to `main` trigger the workflow but require manual approval before jobs run
 
 ### CI/CD Pipeline (ci.yml)
-- **Triggers**: Push/PR to `main` and `dev` branches
+- **Triggers**: PR to `main` (runs after approval), `workflow_dispatch`
 - **Purpose**: Code quality checks (linting and type checking)
 - **Runs**:
   - **Lint job**: Ruff linting with auto-fix and formatting checks
   - **Type-check job**: Ty type checking with concise output
 - **Rationale**:
-  - Ensures code quality before merging
-  - Runs on both main and dev to catch issues early
-  - Fast feedback loop for developers
+  - For branches other than `main`, run CI manually via **Actions → CI/CD Pipeline → Run workflow**
+  - PRs to `main` require approval before lint/type-check jobs run
 
 ### Compatibility Workflow (compatibility.yml)
-- **Triggers**:

   - **live-deployment-test job**: Builds package from wheel, tests installation, runs smoke tests (main branch only)
   - **compatibility-tests job**: Runs compatibility test suite (network tests, may be flaky)
 - **Rationale**:
-  - Ensures compatibility across different OS environments
-  - Tests package installation and basic functionality
-  - Compatibility tests are marked `continue-on-error: true` due to potential network flakiness
+  - Run manually when needed from **Actions → Compatibility → Run workflow**

 ### Continuous Quality
 
-- **CI Pipeline** (`ci.yml`) runs on every push/PR for fast feedback
-- **Version Check** (`version-check.yml`) ensures version consistency
-- **Security** (`security.yml`) runs weekly and on main branch changes
-- **Compatibility** (`compatibility.yml`) runs weekly and on main branch changes
-- **Benchmarks** (`benchmark.yml`) track performance trends
+- **CI Pipeline** (`ci.yml`) and **Test** (`test.yml`): PR to `main` (with approval) or manual run
+- **Version Check** (`version-check.yml`): PR to `main` (with approval) or manual run
+- **Security** (`security.yml`): PR to `main` (with approval), weekly schedule, or manual run
+- **Compatibility** (`compatibility.yml`) and **Benchmarks** (`benchmark.yml`): manual run only

-# DHT Download Start Loop Fix
-
-## Problem Diagnosis
-
-### Symptoms
-- `_start_download_with_dht_peers` being called multiple times for the same DHT peer discovery event
-- Same correlation_id and taskName in logs, indicating duplicate execution
-- Download manager and piece manager being started multiple times
-- Infinite loop of "Starting download with 1 DHT-discovered peers" messages
-
-### Root Causes
-
-1. **No Guard Against Concurrent Calls**: `_start_download_with_dht_peers` had no protection against concurrent execution
-   - Multiple DHT callbacks could trigger it simultaneously
-   - Race condition between checking `_download_started` and setting it
-
-2. **Missing Lock**: No synchronization mechanism to prevent duplicate calls
-   - Multiple async tasks could call `_start_download_with_dht_peers` concurrently
-   - No way to detect if download start is already in progress
-
-3. **Callback Deduplication Not Enough**: The deduplication wrapper filters peers but doesn't prevent multiple calls to `_start_download_with_dht_peers`
-   - Same peer set could trigger multiple calls if callback is invoked multiple times
-   - No check in callback handler to see if download start is already in progress
-
-## Solution Implemented
-
-### 1. Add Lock and Starting Flag
-
-**Location**: `ccbt/session/dht_setup.py:571-598`
-
-**Changes**:
-- Added `_dht_download_start_lock` to synchronize access
-- Added `_dht_download_starting` flag to track if download start is in progress
-- Check `_download_started` at the start of function and return early if already started
-- Check `_dht_download_starting` flag and return early if already starting
-- Set flag to True before starting download to prevent concurrent calls
-
-**Key Code**:
-```python
-# Prevent duplicate calls
-if not hasattr(self.session, "_dht_download_start_lock"):
-    self.session._dht_download_start_lock = asyncio.Lock()
-    self.session._dht_download_starting = False
-
-async with self.session._dht_download_start_lock:
-    # Check if already started
-    if getattr(self.session.download_manager, "_download_started", False):
-        return
-    
-    # Check if already starting
-    if getattr(self.session, "_dht_download_starting", False):
-        return
-    
-    # Mark as starting
-    self.session._dht_download_starting = True
-```
-
-### 2. Clear Flag in Finally Block
-
-**Location**: `ccbt/session/dht_setup.py:676-680`
-
-**Changes**:
-- Added finally block to clear `_dht_download_starting` flag
-- Ensures flag is cleared even if exception occurs
-- Allows retry if download start fails
-
-**Key Code**:
-```python
-finally:
-    # Clear the starting flag even if exception occurs
-    async with self.session._dht_download_start_lock:
-        self.session._dht_download_starting = False
-```
-
-### 3. Check Flag in Callback Handler
-
-**Location**: `ccbt/session/dht_setup.py:197-214`
-
-**Changes**:
-- Check `_dht_download_starting` flag before calling `_start_download_with_dht_peers`
-- Skip call if download start is already in progress
-- Prevents duplicate calls from DHT callback
-
-**Key Code**:
-```python
-if not download_started:
-    # Check if download is already starting
-    is_starting = getattr(self.session, "_dht_download_starting", False)
-    if not is_starting:
-        await self._start_download_with_dht_peers(peer_list, metadata_fetched)
-    else:
-        self.logger.debug("Download start already in progress, skipping duplicate call")
-```
-
-## Impact
-
-### Before Fix
-- `_start_download_with_dht_peers` called multiple times for same peer discovery
-- Download manager and piece manager started multiple times
-- Infinite loop of duplicate download start attempts
-- Race conditions between concurrent calls
-
-### After Fix
-- Only one call to `_start_download_with_dht_peers` per download start
-- Lock prevents concurrent execution
-- Flag prevents duplicate calls even if callback is triggered multiple times
-- Clean error handling with finally block
-
-## Testing Recommendations
-
-1. **Test concurrent DHT callbacks**:
-   - Trigger multiple DHT callbacks simultaneously
-   - Verify only one download start occurs
-   - Verify lock prevents race conditions
-
-2. **Test duplicate peer discovery**:
-   - Discover same peer multiple times
-   - Verify download start is only called once
-   - Verify flag prevents duplicate calls
-
-3. **Test exception handling**:
-   - Cause exception during download start
-   - Verify flag is cleared in finally block
-   - Verify retry is possible after exception
-
-## Files Modified
-
-- `ccbt/session/dht_setup.py`:
-  - `_start_download_with_dht_peers()`: Added lock and starting flag to prevent duplicate calls
-  - `on_dht_peers_discovered()`: Added check for `_dht_download_starting` flag before calling `_start_download_with_dht_peers`

-# Empty Bitfield Peer Disconnect Fix
-
-## Problem Diagnosis
-
-### Symptoms
-- Download stuck in infinite loop selecting pieces 0-6 repeatedly
-- Peer shows `pieces_known=0` but counted as `peers_with_bitfield=1`
-- All peers choked, no pieces available
-- `has_piece=False` for all pieces from peer
-- No new peers being sought or connected
-- Download verification fails
-
-### Root Causes
-
-1. **Empty Bitfield Not Detected**: Peers with empty bitfields (no pieces at all) were kept in `peer_availability` and counted as having bitfields
-   - `pieces_known=0` means `len(peer_avail.pieces) == 0`
-   - But peer was still in `peer_availability`, so `peers_with_bitfield=1`
-   - Piece selector kept selecting pieces from peer with no pieces
-
-2. **No Immediate Disconnect**: Peers with empty bitfields were not disconnected immediately
-   - According to BitTorrent spec, if a peer has no pieces, they may skip sending bitfield
-   - But if they DO send an empty bitfield, we should disconnect immediately
-   - No point keeping a peer with nothing
-
-3. **Piece Selector Not Filtering**: `_select_rarest_first` only checked if peer was in `peer_availability`, not if they had pieces
-   - Filter didn't check `len(peer_avail.pieces) > 0`
-   - Selected pieces from peers with empty bitfields
-
-4. **No New Peer Discovery**: When all current peers have no pieces, no mechanism to seek new peers
-   - Download gets stuck with useless peers
-   - No trigger to announce to trackers or use DHT for new peers
-
-## Solution Implemented
-
-### 1. Filter Empty Bitfields in Piece Selector (`_select_rarest_first`)
-
-**Location**: `ccbt/piece/async_piece_manager.py:3935-3938`
-
-**Changes**:
-- Filter `peers_with_bitfield` to only include peers that actually have pieces
-- Check `len(peer_avail.pieces) > 0` before counting as having bitfield
-- Prevents selecting pieces from peers with empty bitfields
-
-**Key Code**:
-```python
-peers_with_bitfield = [
-    p for p in active_peers
-    if f"{p.peer_info.ip}:{p.peer_info.port}" in self.peer_availability
-    and len(self.peer_availability[f"{p.peer_info.ip}:{p.peer_info.port}"].pieces) > 0
-]
-```
-
-### 2. Immediate Disconnect for Empty Bitfields (`_handle_bitfield`)
-
-**Location**: `ccbt/peer/async_peer_connection.py:5950-5968`
-
-**Changes**:
-- Check if `pieces_count == 0` immediately after bitfield is processed
-- Disconnect peer immediately if they have no pieces at all
-- Return early to prevent further processing
-
-**Key Code**:
-```python
-# CRITICAL FIX: Check if peer has any pieces at all (empty bitfield)
-if pieces_count == 0:
-    self.logger.warning(
-        "Peer %s sent empty bitfield (no pieces at all) - disconnecting immediately",
-        connection.peer_info,
-    )
-    await self._disconnect_peer(connection)
-    return
-```
-
-### 3. Filter Empty Bitfields in Request Validation (`request_piece_from_peers`)
-
-**Location**: `ccbt/piece/async_piece_manager.py:1107-1113`
-
-**Changes**:
-- Filter out peers with empty bitfields before checking availability
-- Only check `actual_availability` from peers that have pieces
-- Prevents requesting pieces from peers with no pieces
-
-**Key Code**:
-```python
-# CRITICAL FIX: Filter out peers with empty bitfields (no pieces at all)
-peers_with_pieces = {
-    k: v for k, v in self.peer_availability.items()
-    if len(v.pieces) > 0
-}
-
-actual_availability = sum(
-    1 for peer_avail in peers_with_pieces.values()
-    if piece_index in peer_avail.pieces
-)
-```
-
-### 4. Peer Evaluation Loop Enhancement (`_peer_evaluation_loop`)
-
-**Location**: `ccbt/peer/async_peer_connection.py:7079-7093`
-
-**Changes**:
-- Check if peer has any pieces at all before checking if they have pieces we need
-- Disconnect peers with empty bitfields immediately in evaluation loop
-- Prevents keeping useless peers in connection pool
-
-**Key Code**:
-```python
-# CRITICAL FIX: Disconnect peers with empty bitfields immediately
-if pieces_count == 0:
-    self.logger.info(
-        "Disconnecting %s: peer has empty bitfield (no pieces at all)",
-        connection.peer_info,
-    )
-    peers_to_recycle.append(connection)
-    continue
-```
-
-## BitTorrent Protocol Compliance
-
-According to BitTorrent specification:
-- **Bitfield Message**: Should be sent immediately after handshake
-- **Empty Bitfield**: If a peer has no pieces, they may skip sending bitfield message
-- **Mutual Interest**: Peers should disconnect when there's no mutual interest
-- **NOT_INTERESTED**: Should be sent when peer has no pieces we need
-
-Our implementation:
-- ✅ Disconnects peers with empty bitfields immediately
-- ✅ Sends NOT_INTERESTED when peer has pieces but none we need
-- ✅ Filters empty bitfields from piece selection
-- ✅ Prevents infinite loops from selecting pieces from peers with no pieces
-
-## Testing Recommendations
-
-1. **Empty Bitfield Test**: Connect to peer that sends empty bitfield, verify immediate disconnect
-2. **Piece Selection Test**: Verify piece selector doesn't select pieces from peers with empty bitfields
-3. **Peer Evaluation Test**: Verify evaluation loop disconnects peers with empty bitfields
-4. **New Peer Discovery Test**: Verify new peers are sought when all current peers have no pieces

-1. **Stale Frequency Data**: When peers disconnect, `piece_frequency` may not be properly decremented, leaving pieces with `frequency > 0` but no actual availability
-2. **Race Conditions**: Frequency counter can be out of sync with `peer_availability` during peer disconnections/reconnections
-3. **Selection Loop**: Selector keeps selecting the same unavailable pieces, causing infinite loop
-
-### Example from Logs
-```
-INFO: Piece selector selected 3 pieces to request: [1244, 1241, 1206]
-INFO: Peer 41.66.97.58:25190 for piece 1244: has_piece=False, can_request=True, choking=False
-WARNING: No available peers for piece 1244: active_peers=1, peers_with_bitfield=1, unchoked=1
-```
-
-The piece was selected because `piece_frequency[1244] > 0`, but no peer actually has it.
-
-## Solution Implemented
-
-### 1. Early Return When No Bitfields (`_select_rarest_first`)
-
-**Location**: `ccbt/piece/async_piece_manager.py:3889-3900`
-
-**Changes**:
-- Check if any peers have bitfields before starting piece selection
-- Early return if `peers_with_bitfield=0` to prevent infinite loops
-- Prevents selecting pieces when peers are connected but haven't sent bitfields yet
-
-**Key Code**:
-```python
-# CRITICAL FIX: Don't select pieces if no peers have bitfields yet
-if self._peer_manager and hasattr(self._peer_manager, "get_active_peers"):
-    active_peers = self._peer_manager.get_active_peers()
-    peers_with_bitfield = [
-        p for p in active_peers
-        if f"{p.peer_info.ip}:{p.peer_info.port}" in self.peer_availability
-    ]
-    if not peers_with_bitfield:
-        # No peers have sent bitfields yet - wait for bitfields before selecting pieces
-        return
-```
-
-### 2. Enhanced Piece Selection Validation (`_select_rarest_first`)
-
-**Location**: `ccbt/piece/async_piece_manager.py:3884-3955`
-
-**Changes**:
-- Always verify piece availability in `peer_availability`, not just `piece_frequency`
-- Calculate `actual_frequency` from `peer_availability` for each piece
-- If `frequency > 0` but `actual_frequency == 0`, update frequency to 0 and skip piece
-- If `frequency != actual_frequency`, update frequency to match reality
-- Only select pieces that actually exist in at least one peer's availability
-
-**Key Code**:
-```python
-# Always verify piece availability in peer_availability
-actual_frequency = sum(
-    1 for peer_avail in self.peer_availability.values()
-    if piece_idx in peer_avail.pieces
-)
-
-if actual_frequency == 0:
-    # Frequency > 0 but no peers actually have the piece
-    # Update frequency to match reality and skip
-    self.piece_frequency[piece_idx] = 0
-    if piece_idx in self.piece_frequency:
-        del self.piece_frequency[piece_idx]
-    continue
-elif actual_frequency != frequency:
-    # Frequency doesn't match actual availability - update it
-    self.piece_frequency[piece_idx] = actual_frequency
-    frequency = actual_frequency
-```
-
-### 3. Request Validation (`request_piece_from_peers`)
-
-**Location**: `ccbt/piece/async_piece_manager.py:1093-1125`
-
-**Changes**:
-- Check if peer availability is empty before requesting
-- Verify that at least one peer actually has the piece before requesting
-- Reset stuck pieces immediately if no peers have bitfields
-- If no peers have the piece, reset frequency and skip request
-
-**Changes**:
-- Verify that at least one peer actually has the piece before requesting
-- If no peers have the piece, reset frequency and skip request
-- Prevents requesting pieces that were selected based on stale frequency data
-
-**Key Code**:
-```python
-# Verify that at least one peer actually has this piece
-actual_availability = sum(
-    1 for peer_avail in self.peer_availability.values()
-    if piece_index in peer_avail.pieces
-)
-if actual_availability == 0:
-    # No peers actually have this piece - reset frequency and skip
-    if piece_index in self.piece_frequency:
-        del self.piece_frequency[piece_index]
-    piece.state = PieceState.MISSING
-    return
-```
-
-## Impact
-
-### Before Fix
-- Pieces with stale frequency data were selected repeatedly
-- Download stalled with pieces stuck in REQUESTED state
-- Infinite loop of selecting unavailable pieces
-- No recovery mechanism for stale frequency data
-
-### After Fix
-- Pieces are only selected if at least one peer actually has them
-- Frequency counter is automatically synchronized with `peer_availability`
-- Stale frequency data is detected and corrected
-- Download continues even after peer disconnections/reconnections
-
-## Technical Details
-
-### Frequency Counter Synchronization
-
-**Normal Updates**:
-- `update_peer_availability()`: Updates frequency when bitfields are received
-- `update_peer_have()`: Updates frequency when HAVE messages are received
-- `_remove_peer()`: Decrements frequency when peers disconnect
-
-**Recovery Mechanism**:
-- Recalculates from `peer_availability` when frequency is 0
-- Verifies frequency matches actual availability before selection
-- Updates frequency to match reality when mismatch detected
-- Handles empty frequency counter (checkpoint restoration)
-
-### Piece Selection Flow
-
-1. **Before Selection**:
-   - Clear stale requested pieces
-   - Recalculate frequency from peer availability (if needed)
-   - Reset stuck pieces
-
-2. **During Selection**:
-   - Check `piece_frequency` for each piece
-   - **NEW**: Verify piece exists in `peer_availability`
-   - **NEW**: Recalculate and update frequency if mismatch detected
-   - Only select pieces that actually exist in peer availability
-
-3. **Before Request**:
-   - **NEW**: Verify piece exists in `peer_availability` again
-   - Skip request if no peers have the piece
-   - Update frequency if stale
-
-4. **After Request**:
-   - Request selected pieces from available peers
-   - Update tracking to prevent duplicates
-
-## Testing Recommendations
-
-1. **Test frequency synchronization**:
-   - Simulate peer disconnection/reconnection
-   - Verify frequency is recalculated correctly
-   - Verify pieces are only selected if peers have them
-
-2. **Test stale frequency detection**:
-   - Manually set `piece_frequency[piece_idx] = 5` but remove piece from all `peer_availability`
-   - Verify selector detects mismatch and updates frequency
-   - Verify piece is not selected
-
-3. **Test piece selection loop**:
-   - Start download with peers that don't have certain pieces
-   - Verify selector doesn't get stuck selecting unavailable pieces
-   - Verify download continues with available pieces
-
-4. **Test DHT peer discovery**:
-   - Start download with DHT-discovered peers
-   - Verify bitfields are received before piece selection
-   - Verify pieces are only selected after bitfields arrive
-
-## Configuration
-
-No new configuration options required. The fix is automatic and transparent.
-
-## Related Issues
-
-- Fixes infinite loop in piece selection when peers don't have selected pieces
-- Fixes stale frequency data causing download stalls
-- Improves synchronization between `piece_frequency` and `peer_availability`
-- Prevents requesting pieces that no peer has
-
-## Files Modified
-
-- `ccbt/piece/async_piece_manager.py`:
-  - `_select_rarest_first()`: Added peer availability verification
-  - `request_piece_from_peers()`: Added availability check before requesting

-# Peer Timeout and No-Pieces Disconnect Fix
-
-## Problem Diagnosis
-
-### Symptoms
-- Peers connected but showing `pieces_known=0` (no bitfields received)
-- All peers choked (`choking=True`, `can_request=False`)
-- `peers_with_bitfield=0` - no peers have sent bitfields
-- Peers kept in connection pool even when they have no pieces we need
-- Infinite loops selecting pieces that no peer has
-
-### Root Causes
-
-1. **No Bitfield Timeout**: Peers that don't send bitfield after handshake are kept indefinitely
-   - According to BitTorrent spec, bitfield should be sent immediately after handshake
-   - No timeout mechanism to disconnect peers that don't follow protocol
-
-2. **No Mutual Interest Check**: Peers with no pieces we need are kept in connection pool
-   - BitTorrent protocol: peers should disconnect when there's no mutual interest
-   - No logic to check if peer has any pieces we need after bitfield is received
-   - No timeout to disconnect useless peers
-
-3. **Missing NOT_INTERESTED Message**: When peer has no pieces we need, we don't send NOT_INTERESTED
-   - BitTorrent protocol requires NOT_INTERESTED when we're not interested
-   - This helps peers know we don't need anything from them
-
-## Solution Implemented
-
-### 1. Bitfield Timeout Monitor
-
-**Location**: `ccbt/peer/async_peer_connection.py:3644-3675`
-
-**Changes**:
-- Start timeout monitor after handshake completes
-- Disconnect peers that don't send bitfield within 60 seconds
-- Cancel timeout monitor when bitfield is received
-- Complies with BitTorrent protocol (bitfield should be sent immediately after handshake)
-
-**Key Code**:
-```python
-# Start bitfield timeout monitor
-bitfield_timeout = 60.0  # 60 seconds timeout
-async def bitfield_timeout_monitor():
-    await asyncio.sleep(bitfield_timeout)
-    if connection.state not in (BITFIELD_RECEIVED, ACTIVE, CHOKED):
-        # Bitfield not received - disconnect
-        await self._disconnect_peer(connection)
-```
-
-### 2. Check for No Useful Pieces After Bitfield
-
-**Location**: `ccbt/peer/async_peer_connection.py:5891-5967`
-
-**Changes**:
-- After bitfield is received, check if peer has ANY pieces we need
-- If peer has no pieces we need:
-  - Send NOT_INTERESTED message (BitTorrent protocol compliance)
-  - Schedule disconnect after 10-second grace period
-  - Grace period allows peer to send HAVE messages for new pieces
-
-**Key Code**:
-```python
-# Check if peer has any pieces we need
-has_needed_piece = False
-for piece_idx in missing_pieces:
-    if bitfield has piece_idx:
-        has_needed_piece = True
-        break
-
-if not has_needed_piece:
-    # Send NOT_INTERESTED and schedule disconnect
-    await send_not_interested(connection)
-    await delayed_disconnect()  # 10 second grace period
-```
-
-### 3. Periodic Health Check for Useless Peers
-
-**Location**: `ccbt/peer/async_peer_connection.py:7058-7080`
-
-**Changes**:
-- In `_peer_evaluation_loop`, check all active peers
-- If peer has bitfield but no pieces we need, disconnect after grace period (30 seconds)
-- Prevents keeping useless connections that waste resources
-
-**Key Code**:
-```python
-# Check if peer has no pieces we need
-if connection.is_active() and connection.peer_state.bitfield:
-    has_needed_piece = check_if_peer_has_missing_pieces(connection)
-    if not has_needed_piece:
-        connection_age = time.time() - connection.stats.last_activity
-        if connection_age > 30.0:  # Grace period
-            await self._disconnect_peer(connection)
-```
-
-## BitTorrent Protocol Compliance
-
-### Bitfield Message (BEP 3)
-- **Requirement**: Bitfield should be sent immediately after handshake
-- **Our Fix**: Timeout peers that don't send bitfield within 60 seconds
-
-### Mutual Interest (BEP 3)
-- **Requirement**: Peers should disconnect when there's no mutual interest
-- **Our Fix**: 
-  - Send NOT_INTERESTED when peer has no pieces we need
-  - Disconnect peers with no useful pieces after grace period
-
-### NOT_INTERESTED Message (BEP 3)
-- **Requirement**: Send NOT_INTERESTED when we're not interested in peer
-- **Our Fix**: Send NOT_INTERESTED when peer has no pieces we need
-
-## Impact
-
-### Before Fix
-- Peers without bitfields kept indefinitely
-- Peers with no useful pieces kept in connection pool
-- Wasted resources on useless connections
-- Infinite loops selecting pieces no peer has
-
-### After Fix
-- Peers that don't send bitfield are disconnected after 60 seconds
-- Peers with no useful pieces are disconnected after grace period
-- NOT_INTERESTED sent to peers with no pieces we need
-- Connection pool only keeps useful peers
-- No infinite loops - peers are disconnected if they have nothing we need
-
-## Configuration
-
-No new configuration options required. The fix uses:
-- Bitfield timeout: 60 seconds (hardcoded, follows BitTorrent spec)
-- Grace period for no-pieces disconnect: 10 seconds (immediate) + 30 seconds (periodic check)
-- Peer evaluation interval: 30 seconds (configurable via `config.network.peer_evaluation_interval`)
-
-## Testing Recommendations
-
-1. **Test bitfield timeout**:
-   - Connect to peer that doesn't send bitfield
-   - Verify peer is disconnected after 60 seconds
-
-2. **Test no-pieces disconnect**:
-   - Connect to peer that has no pieces we need
-   - Verify NOT_INTERESTED is sent
-   - Verify peer is disconnected after grace period
-
-3. **Test periodic health check**:
-   - Connect to peer with no useful pieces
-   - Wait for periodic evaluation loop
-   - Verify peer is disconnected
-
-4. **Test grace period**:
-   - Connect to peer with no pieces we need
-   - Verify peer is kept for grace period (30 seconds)
-   - Verify peer is disconnected after grace period
-
-## Files Modified
-
-- `ccbt/peer/async_peer_connection.py`:
-  - `_handle_bitfield()`: Added check for no useful pieces, send NOT_INTERESTED, schedule disconnect
-  - `_connect_to_peer()`: Added bitfield timeout monitor
-  - `_peer_evaluation_loop()`: Added periodic check for peers with no useful pieces
