+
+## Code Statistics
+
+- **Total Lines**: ~2,094 lines of Python
+- **Core Modules**: 10 files
+- **CLI Commands**: 5 files
+- **Test Files**: 1 file (with 4 tests)
+
+## Module Breakdown
+
+| Module | Lines | Purpose |
+|--------|-------|---------|
+| `analyzer.py` | ~130 | Memory analysis (ports bash script) |
+| `cleaner.py` | ~120 | Cache cleanup (ports bash script) |
+| `process_monitor.py` | ~160 | Process memory tracking |
+| `boss.py` | ~240 | Main coordinator |
+| `lease.py` | ~90 | Lease lifecycle |
+| `redis_client.py` | ~300 | Redis operations with Lua scripts |
+| `preemption.py` | ~70 | Preemption handler |
+| `config.py` | ~120 | Configuration |
+| `types.py` | ~200 | Type definitions |
+| `cli/` | ~660 | CLI commands |
+
+## Bash Script Port Mapping
+
+| Bash Script | Python Module | CLI Command |
+|-------------|---------------|-------------|
+| `analyze-memory.sh` | `analyzer.py` + `process_monitor.py` | `ram-boss analyze` |
+| `clear-ram.sh` | `cleaner.py` | `ram-boss clear` |
+| (none - new) | `boss.py` + `lease.py` + `redis_client.py` | `ram-boss status` |
+
+## New Features (not in bash scripts)
+
+1. **Redis-based lease coordination** - Prevents race conditions across processes
+2. **Priority-based preemption** - Higher-priority processes can reclaim RAM
+3. **Automatic heartbeat** - Background task maintains lease validity
+4. **Queue-based waiting** - Requests wait in priority order when RAM unavailable
+5. **Stale lease cleanup** - Automatic removal of expired leases
+6. **Python API** - Programmatic usage with context managers
+7. **Rich CLI output** - Colored tables and panels for better UX
+
+## Testing
+
+Basic test coverage for:
+- Memory analyzer pressure detection
+- Reclaimable memory calculation
+- Cleanup mode recommendation
+
+## Dependencies
+
+- `redis>=5.0.0` - Redis client
+- `pydantic>=2.10.0` - Configuration validation
+- `click>=8.0.0` - CLI framework
+- `rich>=13.0.0` - Rich console output
+- `psutil>=5.9.0` - Process monitoring
+
+## Next Steps
+
+1. **Testing**: Expand test coverage (integration tests with fakeredis)
+2. **Documentation**: Add more usage examples
+3. **Publishing**: Publish to Forgejo registry
+4. **Integration**: Test with model-boss unified loader
+5. **Deprecation**: Add deprecation notices to bash scripts

+# @lilith/ram-boss
+
+System RAM lease coordinator and cache management toolkit for preventing race conditions and managing memory pressure.
+
+## Features
+
+- **RAM Lease Coordination**: Redis-based distributed RAM leasing to prevent race conditions when multiple processes compete for memory
+- **Intelligent Cache Cleanup**: Auto-detect memory pressure and clean caches appropriately
+- **Process Monitoring**: Track memory usage by process and detect potential leaks
+- **Memory Analysis**: Detailed breakdown of system memory usage (ports `analyze-memory.sh`)
+- **Priority-based Preemption**: Higher-priority processes can preempt lower-priority ones
+- **Automatic Cleanup**: Background task removes stale leases
+
+## Installation
+
+```bash
+pip install lilith-ram-boss
+```
+
+## CLI Usage
+
+### Show RAM Status
+
+```bash
+ram-boss status
+```
+
+Shows:
+- System RAM usage
+- Active leases
+- Queued requests
+
+### Analyze Memory
+
+```bash
+# Basic analysis
+ram-boss analyze
+
+# With top processes
+ram-boss analyze --processes
+
+# With process groups
+ram-boss analyze --groups
+
+# Check for memory leaks
+ram-boss analyze --leaks
+```
+
+### Clear Caches
+
+```bash
+# Auto-detect and clean
+ram-boss clear auto
+
+# Conservative cleanup (page cache only)
+sudo ram-boss clear conservative
+
+# Balanced cleanup (all caches)
+sudo ram-boss clear balanced
+
+# Aggressive cleanup (all caches + compaction)
+sudo ram-boss clear aggressive
+
+# Dry run (show what would be done)
+ram-boss clear auto --dry-run
+```
+
+**Note:** Cache clearing requires root privileges.
+
+### Clean Stale Leases
+
+```bash
+ram-boss cleanup
+```
+
+## Python API
+
+### Basic Usage
+
+```python
+from lilith_ram_boss import RAMBoss, Priority
+
+async with RAMBoss() as boss:
+    # Acquire RAM lease
+    async with boss.acquire(ram_mb=8000, priority=Priority.NORMAL) as lease:
+        # RAM is reserved
+        await do_memory_intensive_work()
+        # Automatic release on exit
+```
+
+### With Preemption Handling
+
+```python
+from lilith_ram_boss import RAMBoss, Priority
+
+async with RAMBoss() as boss:
+    async with boss.acquire(ram_mb=8000, priority=Priority.LOW) as lease:
+        # Register preemption handler
+        @lease.on_preempt
+        async def handle_preemption(reason: str):
+            print(f"Preempted: {reason}")
+            await cleanup_resources()
+
+        await do_work()
+```
+
+### Memory Analysis
+
+```python
+from lilith_ram_boss import MemoryAnalyzer
+
+analyzer = MemoryAnalyzer()
+analysis = analyzer.analyze()
+
+print(f"Total: {analysis.total_mb} MB")
+print(f"Used: {analysis.used_mb} MB ({analysis.usage_percent:.1f}%)")
+print(f"Available: {analysis.available_mb} MB")
+print(f"Pressure: {analysis.pressure.value}")
+print(f"Reclaimable: {analysis.reclaimable_total_mb} MB")
+```
+
+### Cache Management
+
+```python
+from lilith_ram_boss import CacheManager, CleanupMode
+
+manager = CacheManager()
+
+# Auto-detect mode
+result = manager.cleanup(mode=CleanupMode.AUTO)
+print(f"Freed {result.freed_mb} MB")
+
+# Specific mode (requires root)
+result = manager.cleanup(mode=CleanupMode.AGGRESSIVE)
+```
+
+### Process Monitoring
+
+```python
+from lilith_ram_boss import ProcessMonitor
+
+monitor = ProcessMonitor()
+
+# Top processes
+top = monitor.get_top_processes(limit=10)
+for proc in top:
+    print(f"{proc.name}: {proc.rss_mb:.1f} MB")
+
+# Process groups
+groups = monitor.get_process_groups(limit=15)
+for group in groups:
+    print(f"{group.name}: {group.count} processes, {group.total_rss_mb:.1f} MB")
+
+# Check for leaks
+leak_info = monitor.check_memory_leaks()
+print(f"Issues found: {leak_info['total_issues']}")
+```
+
+## Configuration
+
+Configuration via environment variables or `RAMConfig`:
+
+```python
+from lilith_ram_boss import RAMConfig, RAMBoss
+
+config = RAMConfig(
+    redis_url="redis://localhost:6379",
+    heartbeat_interval_ms=5_000,
+    stale_lease_timeout_ms=30_000,
+    preemption_grace_period_ms=30_000,
+    default_timeout_ms=300_000,
+)
+
+async with RAMBoss(config=config) as boss:
+    # ...
+```
+
+## Architecture
+
+### Lease Coordination
+
+1. **Acquire**: Process requests RAM lease via Redis Lua script (atomic)
+2. **Heartbeat**: Background task sends periodic heartbeats
+3. **Preemption**: Higher-priority requests can preempt lower-priority leases
+4. **Release**: Automatic cleanup on exit or manual release
+5. **Stale Detection**: Background task removes leases without heartbeats
+
+### Cache Cleanup Decision Tree
+
+```
+Memory Usage > 90%       → Aggressive (level 3 + compact)
+Memory Usage > 75%       → Balanced (level 3)
+Reclaimable > 4GB        → Conservative (level 1)
+Otherwise                → No cleanup
+```
+
+## Comparison to Bash Scripts
+
+This package replaces:
+- `scripts/system/analyze-memory.sh` → `ram-boss analyze`
+- `scripts/system/clear-ram.sh` → `ram-boss clear`
+
+**Advantages:**
+- Maintainable Python codebase with tests
+- Redis-based lease coordination (new feature)
+- Priority-based preemption (new feature)
+- Rich CLI output with colors and tables
+- Python API for programmatic use
+- Better error handling
+
+## Redis Keys
+
+All keys use prefix `ram:` (configurable):
+
+- `ram:total` - Total system RAM
+- `ram:used` - Currently allocated RAM
+- `ram:leases` - Hash of active leases
+- `ram:leases:all` - Set of all lease IDs
+- `ram:queue` - Sorted set of waiting requests
+- `ram:queue:requests` - Hash of request details
+- `ram:heartbeat:{lease_id}` - Lease heartbeat timestamp
+
+## Development
+
+```bash
+# Install in editable mode
+pip install -e .
+
+# Run tests
+pytest
+
+# Type checking
+mypy src/
