+
+### Async Client Pattern (Important!)
+
+**All MCP tools and CLI commands use the context manager pattern for HTTP clients:**
+
+```python
+from basic_memory.mcp.async_client import get_client
+
+async def my_mcp_tool():
+    async with get_client() as client:
+        # Use client for API calls
+        response = await call_get(client, "/path")
+        return response
+```
+
+**Do NOT use:**
+- ❌ `from basic_memory.mcp.async_client import client` (deprecated module-level client)
+- ❌ Manual auth header management
+- ❌ `inject_auth_header()` (deleted)
+
+**Key principles:**
+- Auth happens at client creation, not per-request
+- Proper resource management via context managers
+- Supports three modes: Local (ASGI), CLI cloud (HTTP + auth), Cloud app (factory injection)
+- Factory pattern enables dependency injection for cloud consolidation
+
+**For cloud app integration:**
+```python
+from basic_memory.mcp import async_client
+
+# Set custom factory before importing tools
+async_client.set_client_factory(your_custom_factory)
+```
+
+See SPEC-16 for full context manager refactor details.

 ## Testing Guidelines
 
-- **Coverage Target**: We aim for 100% test coverage for all code
+### Test Structure
+
+Basic Memory uses two test directories with unified coverage reporting:
+
+- **`tests/`**: Unit tests that test individual components in isolation
+  - Fast execution with extensive mocking
+  - Test individual functions, classes, and modules
+  - Run with: `just test-unit` (no coverage, fast)
+
+- **`test-int/`**: Integration tests that test real-world scenarios
+  - Test full workflows with real database and file operations
+  - Include performance benchmarks
+  - More realistic but slower than unit tests
+  - Run with: `just test-int` (no coverage, fast)
+
+### Running Tests
+
+```bash
+# Run all tests with unified coverage report
+just test
+
+# Run only unit tests (fast iteration)
+just test-unit
+
+# Run only integration tests
+just test-int
+
+# Generate HTML coverage report
+just coverage
+
+# Run specific test
+pytest tests/path/to/test_file.py::test_function_name
+
+# Run tests excluding benchmarks
+pytest -m "not benchmark"
+
+# Run only benchmark tests
+pytest -m benchmark test-int/test_sync_performance_benchmark.py
+```
+
+### Performance Benchmarks
+
+The `test-int/test_sync_performance_benchmark.py` file contains performance benchmarks that measure sync and indexing speed:
+
+- `test_benchmark_sync_100_files` - Small repository performance
+- `test_benchmark_sync_500_files` - Medium repository performance
+- `test_benchmark_sync_1000_files` - Large repository performance (marked slow)
+- `test_benchmark_resync_no_changes` - Re-sync performance baseline
+
+Run benchmarks with:
+```bash
+# Run all benchmarks (excluding slow ones)
+pytest test-int/test_sync_performance_benchmark.py -v -m "benchmark and not slow"
+
+# Run all benchmarks including slow ones
+pytest test-int/test_sync_performance_benchmark.py -v -m benchmark
+
+# Run specific benchmark
+pytest test-int/test_sync_performance_benchmark.py::test_benchmark_sync_100_files -v
+```
+
+See `test-int/BENCHMARKS.md` for detailed benchmark documentation.
+
+### Testing Best Practices
+
+- **Coverage Target**: We aim for high test coverage for all code
 - **Test Framework**: Use pytest for unit and integration tests
-- **Mocking**: Use pytest-mock for mocking dependencies only when necessary
+- **Mocking**: Avoid mocking in integration tests; use sparingly in unit tests
 - **Edge Cases**: Test both normal operation and edge cases
 - **Database Testing**: Use in-memory SQLite for testing database operations
 - **Fixtures**: Use async pytest fixtures for setup and teardown
+- **Markers**: Use `@pytest.mark.benchmark` for benchmarks, `@pytest.mark.slow` for slow tests

+# SPEC-15: Configuration Persistence via Tigris for Cloud Tenants
+
+## Why
+
+We need to persist Basic Memory configuration across Fly.io deployments without using persistent volumes or external databases.
+
+**Current Problems:**
+- `~/.basic-memory/config.json` lost on every deployment (project configuration)
+- `~/.basic-memory/memory.db` lost on every deployment (search index)
+- Persistent volumes break clean deployment workflow
+- External databases (Turso) require per-tenant token management
+
+**The Insight:**
+The SQLite database is just an **index cache** of the markdown files. It can be rebuilt in seconds from the source markdown files in Tigris. Only the small `config.json` file needs true persistence.
+
+**Solution:**
+- Store `config.json` in Tigris bucket (persistent, small file)
+- Rebuild `memory.db` on startup from markdown files (fast, ephemeral)
+- No persistent volumes, no external databases, no token management
+
+## What
+
+Store Basic Memory configuration in the Tigris bucket and rebuild the database index on tenant machine startup.
+
+**Affected Components:**
+- `basic-memory/src/basic_memory/config.py` - Add configurable config directory
+
+**Architecture:**
+
+```bash
+# Tigris Bucket (persistent, mounted at /mnt/tigris)
+/mnt/tigris/
+  ├── .basic-memory/
+  │   └── config.json          # ← Project configuration (persistent, accessed via BASIC_MEMORY_CONFIG_DIR)
+  └── projects/                 # ← Markdown files (persistent)
+      ├── project1/
+      └── project2/
+
+# Fly Machine (ephemeral)
+~/.basic-memory/
+  └── memory.db                # ← Rebuilt on startup (fast local disk)
+```
+
+## How (High Level)
+
+### 1. Add Configurable Config Directory to Basic Memory
+
+Currently `ConfigManager` hardcodes `~/.basic-memory/config.json`. Add environment variable to override:
+
+```python
+# basic-memory/src/basic_memory/config.py
+
+class ConfigManager:
+    """Manages Basic Memory configuration."""
+
+    def __init__(self) -> None:
+        """Initialize the configuration manager."""
+        home = os.getenv("HOME", Path.home())
+        if isinstance(home, str):
+            home = Path(home)
+
+        # Allow override via environment variable
+        if config_dir := os.getenv("BASIC_MEMORY_CONFIG_DIR"):
+            self.config_dir = Path(config_dir)
+        else:
+            self.config_dir = home / DATA_DIR_NAME
+
+        self.config_file = self.config_dir / CONFIG_FILE_NAME
+
+        # Ensure config directory exists
+        self.config_dir.mkdir(parents=True, exist_ok=True)
+```
+
+### 2. Rebuild Database on Startup
+
+Basic Memory already has the sync functionality. Just ensure it runs on startup:
+
+```python
+# apps/api/src/basic_memory_cloud_api/main.py
+
+@app.on_event("startup")
+async def startup_sync():
+    """Rebuild database index from Tigris markdown files."""
+    logger.info("Starting database rebuild from Tigris")
+
+    # Initialize file sync (rebuilds index from markdown files)
+    app_config = ConfigManager().config
+    await initialize_file_sync(app_config)
+
+    logger.info("Database rebuild complete")
+```
+
+### 3. Environment Configuration
+
+```bash
+# Machine environment variables
+BASIC_MEMORY_CONFIG_DIR=/mnt/tigris/.basic-memory  # Config read/written directly to Tigris
+# memory.db stays in default location: ~/.basic-memory/memory.db (local ephemeral disk)
+```
+
+## Implementation Task List
+
+### Phase 1: Basic Memory Changes ✅
+- [x] Add `BASIC_MEMORY_CONFIG_DIR` environment variable support to `ConfigManager.__init__()`
+- [x] Test config loading from custom directory
+- [x] Update tests to verify custom config dir works
+
+### Phase 2: Tigris Bucket Structure
+- [ ] Ensure `.basic-memory/` directory exists in Tigris bucket on tenant creation
+- [ ] Initialize `config.json` in Tigris on first tenant deployment
+- [ ] Verify TigrisFS handles hidden directories correctly
+
+### Phase 3: Deployment Integration
+- [ ] Set `BASIC_MEMORY_CONFIG_DIR` environment variable in machine deployment
+- [ ] Ensure database rebuild runs on machine startup via initialization sync
+- [ ] Handle first-time tenant setup (no config exists yet)
+- [ ] Test deployment workflow with config persistence
+
+### Phase 4: Testing
+- [x] Unit tests for config directory override
+- [ ] Integration test: deploy → write config → redeploy → verify config persists
+- [ ] Integration test: deploy → add project → redeploy → verify project in config
+- [ ] Performance test: measure db rebuild time on startup
+
+### Phase 5: Documentation
+- [ ] Document config persistence architecture
+- [ ] Update deployment runbook
+- [ ] Document startup sequence and timing
+
+## How to Evaluate
+
+### Success Criteria
+
+1. **Config Persistence**
+   - [ ] config.json persists across deployments
+   - [ ] Projects list maintained across restarts
+   - [ ] No manual configuration needed after redeploy
+
+2. **Database Rebuild**
+   - [ ] memory.db rebuilt on startup in < 30 seconds
+   - [ ] All entities indexed correctly
+   - [ ] Search functionality works after rebuild
+
+3. **Performance**
+   - [ ] SQLite queries remain fast (local disk)
+   - [ ] Config reads acceptable (symlink to Tigris)
+   - [ ] No noticeable performance degradation
+
+4. **Deployment Workflow**
+   - [ ] Clean deployments without volumes
+   - [ ] No new external dependencies
+   - [ ] No secret management needed
+
+### Testing Procedure
+
+1. **Config Persistence Test**
+   ```bash
+   # Deploy tenant
+   POST /tenants → tenant_id
+
+   # Add a project
+   basic-memory project add "test-project" ~/test
+
+   # Verify config has project
+   cat /mnt/tigris/.basic-memory/config.json
+
+   # Redeploy machine
+   fly deploy --app basic-memory-{tenant_id}
+
+   # Verify project still exists
+   basic-memory project list
+   ```
+
+2. **Database Rebuild Test**
+   ```bash
+   # Create notes
+   basic-memory write "Test Note" --content "..."
+
+   # Redeploy (db lost)
+   fly deploy --app basic-memory-{tenant_id}
+
+   # Wait for startup sync
+   sleep 10
+
+   # Verify note is indexed
+   basic-memory search "Test Note"
+   ```
+
+3. **Performance Benchmark**
+   ```bash
+   # Time the startup sync
+   time basic-memory sync
+
+   # Should be < 30 seconds for typical tenant
+   ```
+
+## Benefits Over Alternatives
+
+**vs. Persistent Volumes:**
+- ✅ Clean deployment workflow
+- ✅ No volume migration needed
+- ✅ Simpler infrastructure
+
+**vs. Turso (External Database):**
+- ✅ No per-tenant token management
+- ✅ No external service dependencies
+- ✅ No additional costs
+- ✅ Simpler architecture
+
+**vs. SQLite on FUSE:**
+- ✅ Fast local SQLite performance
+- ✅ Only slow reads for small config file
+- ✅ Database queries remain fast
+
+## Implementation Assignment
+
+**Primary Agent:** `python-developer`
+- Add `BASIC_MEMORY_CONFIG_DIR` environment variable to ConfigManager
+- Update deployment workflow to set environment variable
+- Ensure startup sync runs correctly
+
+**Review Agent:** `system-architect`
+- Validate architecture simplicity
+- Review performance implications
+- Assess startup timing
+
+## Dependencies
+
+- **Internal:** TigrisFS must be working and stable

+
+# SPEC-16: MCP Cloud Service Consolidation
+
+## Why
+
+### Original Architecture Constraints (Now Removed)
+
+The current architecture deploys MCP Gateway and Cloud Service as separate Fly.io apps:
+
+**Current Flow:**
+```
+LLM Client → MCP Gateway (OAuth) → Cloud Proxy (JWT + header signing) → Tenant API (JWT + header validation)
+            apps/mcp                apps/cloud /proxy                    apps/api
+```
+
+This separation was originally necessary because:
+1. **Stateful SSE requirement** - MCP needed server-sent events with session state for active project tracking
+2. **fastmcp.run limitation** - The FastMCP demo helper didn't support worker processes
+
+### Why These Constraints No Longer Apply
+
+1. **State externalized** - Project state moved from in-memory to LLM context (external state)
+2. **HTTP transport enabled** - Switched from SSE to stateless HTTP for MCP tools
+3. **Worker support added** - Converted from `fastmcp.run()` to `uvicorn.run()` with workers
+
+### Current Problems
+
+- **Unnecessary HTTP hop** - MCP tools call Cloud /proxy endpoint which calls tenant API
+- **Higher latency** - Extra network round trip for every MCP operation
+- **Increased costs** - Two separate Fly.io apps instead of one
+- **Complex deployment** - Two services to deploy, monitor, and maintain
+- **Resource waste** - Separate database connections, HTTP clients, telemetry overhead
+
+## What
+
+### Services Affected
+
+1. **apps/mcp** - MCP Gateway service (to be merged)
+2. **apps/cloud** - Cloud service (will receive MCP functionality)
+3. **basic-memory** - Update `async_client.py` to use direct calls
+4. **Deployment** - Consolidate Fly.io deployment to single app
+
+### Components Changed
+
+**Merged:**
+- MCP middleware and telemetry into Cloud app
+- MCP tools mounted on Cloud FastAPI instance
+- ProxyService used directly by MCP tools (not via HTTP)
+
+**Kept:**
+- `/proxy` endpoint (still needed by web UI)
+- All existing Cloud routes (provisioning, webhooks, etc.)
+- Dual validation in tenant API (JWT + signed headers)
+
+**Removed:**
+- apps/mcp directory
+- Separate MCP Fly.io deployment
+- HTTP calls from MCP tools to /proxy endpoint
+
+## How (High Level)
+
+### 1. Mount FastMCP on Cloud FastAPI App
+
+```python
+# apps/cloud/src/basic_memory_cloud/main.py
+
+from basic_memory.mcp.server import mcp
+from basic_memory_cloud_mcp.middleware import TelemetryMiddleware
+
+# Configure MCP OAuth
+auth_provider = AuthKitProvider(
+    authkit_domain=settings.authkit_domain,
+    base_url=settings.authkit_base_url,
+    required_scopes=[],
+)
+mcp.auth = auth_provider
+mcp.add_middleware(TelemetryMiddleware())
+
+# Mount MCP at /mcp endpoint
+mcp_app = mcp.http_app(path="/mcp", stateless_http=True)
+app.mount("/mcp", mcp_app)
+
+# Existing Cloud routes stay at root
+app.include_router(proxy_router)
+app.include_router(provisioning_router)
+# ... etc
+```
+
+### 2. Direct Tenant Transport (No HTTP Hop)
+
+Instead of calling `/proxy`, MCP tools call tenant APIs directly via custom httpx transport:
+
+```python
+# apps/cloud/src/basic_memory_cloud/transports/tenant_direct.py
+
+from httpx import AsyncBaseTransport, Request, Response
+from fastmcp.server.dependencies import get_http_headers
+import jwt
+
+class TenantDirectTransport(AsyncBaseTransport):
+    """Direct transport to tenant APIs, bypassing /proxy endpoint."""
+
+    async def handle_async_request(self, request: Request) -> Response:
+        # 1. Get JWT from current MCP request (via FastMCP DI)
+        http_headers = get_http_headers()
+        auth_header = http_headers.get("authorization") or http_headers.get("Authorization")
+        token = auth_header.replace("Bearer ", "")
+        claims = jwt.decode(token, options={"verify_signature": False})
+        workos_user_id = claims["sub"]
+
+        # 2. Look up tenant for user
+        tenant = await tenant_service.get_tenant_by_user_id(workos_user_id)
+
+        # 3. Build tenant app URL with signed headers
+        fly_app_name = f"{settings.tenant_prefix}-{tenant.id}"
+        target_url = f"https://{fly_app_name}.fly.dev{request.url.path}"
+
+        headers = dict(request.headers)
+        signer = create_signer(settings.bm_tenant_header_secret)
+        headers.update(signer.sign_tenant_headers(tenant.id))
+
+        # 4. Make direct call to tenant API
+        response = await self.client.request(
+            method=request.method, url=target_url,
+            headers=headers, content=request.content
+        )
+        return response
+```
+
+Then override basic-memory's client before mounting MCP:
+
+```python
+# apps/cloud/src/basic_memory_cloud/main.py
+
+from basic_memory.mcp import async_client
+from basic_memory_cloud.transports.tenant_direct import TenantDirectTransport
+
+# Override basic-memory's HTTP client with direct transport
+async_client.client = httpx.AsyncClient(
+    transport=TenantDirectTransport(),
+    base_url="http://direct"
+)
+
+# Now mount MCP - tools will use direct transport
+app.mount("/mcp", mcp_app)
+```
+
+**Key benefits:**
+- No changes to basic-memory code
+- Per-request tenant resolution via FastMCP DI
+- Eliminates HTTP hop entirely (~50 lines of code)
+- /proxy endpoint remains for web UI
+
+### 3. Keep /proxy Endpoint for Web UI
+
+The existing `/proxy` HTTP endpoint remains functional for:
+- Web UI requests
+- Future external API consumers
+- Backward compatibility
+
+### 4. Security: Maintain Dual Validation
+
+**Do NOT remove JWT validation from tenant API.** Keep defense in depth:
+
+```python
+# apps/api - Keep both validations
+1. JWT validation (from WorkOS token)
+2. Signed header validation (from Cloud/MCP)
+```
+
+This ensures if the Cloud service is compromised, attackers still cannot access tenant APIs without valid JWTs.
+
+### 5. Deployment Changes
+
+**Before:**
+- `apps/mcp/fly.template.toml` → MCP Gateway deployment
+- `apps/cloud/fly.template.toml` → Cloud Service deployment
+
+**After:**
+- Remove `apps/mcp/fly.template.toml`
+- Update `apps/cloud/fly.template.toml` to expose port 8000 for both /mcp and /proxy
+- Update deployment scripts to deploy single consolidated app
+
+
+## Basic Memory Dependency: Async Client Refactor
+
+### Problem
+The current `basic_memory.mcp.async_client` creates a module-level `client` at import time:
+```python
+client = create_client()  # Runs immediately when module is imported
+```
+
+This prevents dependency injection - by the time we can override it, tools have already imported it.
+
+### Solution: Context Manager Pattern with Auth at Client Creation
+
+Refactor basic-memory to use httpx's context manager pattern instead of module-level client.
+
+**Key principle:** Authentication happens at client creation time, not per-request.
+
+```python
+# basic_memory/src/basic_memory/mcp/async_client.py
+from contextlib import asynccontextmanager
+from httpx import AsyncClient, ASGITransport, Timeout
+
+# Optional factory override for dependency injection
+_client_factory = None
+
+def set_client_factory(factory):
+    """Override the default client factory (for cloud app, testing, etc)."""
+    global _client_factory
+    _client_factory = factory
+
+@asynccontextmanager
+async def get_client():
+    """Get an AsyncClient as a context manager.
+
+    Usage:
+        async with get_client() as client:
+            response = await client.get(...)
+    """
+    if _client_factory:
+        # Cloud app: custom transport handles everything
+        async with _client_factory() as client:
+            yield client
+    else:
+        # Default: create based on config
+        config = ConfigManager().config
+        timeout = Timeout(connect=10.0, read=30.0, write=30.0, pool=30.0)
+
+        if config.cloud_mode_enabled:
+            # CLI cloud mode: inject auth when creating client
+            from basic_memory.cli.auth import CLIAuth
+
+            auth = CLIAuth(
+                client_id=config.cloud_client_id,
+                authkit_domain=config.cloud_domain
+            )
+            token = await auth.get_valid_token()
+
+            if not token:
+                raise RuntimeError(
+                    "Cloud mode enabled but not authenticated. "
+                    "Run 'basic-memory cloud login' first."
+                )
+
+            # Auth header set ONCE at client creation
+            async with AsyncClient(
+                base_url=f"{config.cloud_host}/proxy",
+                headers={"Authorization": f"Bearer {token}"},
+                timeout=timeout
+            ) as client:
+                yield client
+        else:
+            # Local mode: ASGI transport
+            async with AsyncClient(
+                transport=ASGITransport(app=fastapi_app),
+                base_url="http://test",
+                timeout=timeout
+            ) as client:
+                yield client
+```
+
+**Tool Updates:**
+```python
+# Before: from basic_memory.mcp.async_client import client
+from basic_memory.mcp.async_client import get_client
+
+async def read_note(...):
+    # Before: response = await call_get(client, path, ...)
+    async with get_client() as client:
+        response = await call_get(client, path, ...)
+        # ... use response
+```
+
+**Cloud Usage:**
+```python
+from contextlib import asynccontextmanager
+from basic_memory.mcp import async_client
+
+@asynccontextmanager
+async def tenant_direct_client():
+    """Factory for creating clients with tenant direct transport."""
+    client = httpx.AsyncClient(
+        transport=TenantDirectTransport(),
+        base_url="http://direct",
+    )
+    try:
+        yield client
+    finally:
+        await client.aclose()
+
+# Before importing MCP tools:
+async_client.set_client_factory(tenant_direct_client)
+
+# Now import - tools will use our factory
+import basic_memory.mcp.tools
+```
+
+### Benefits
+- **No module-level state** - client created only when needed
+- **Proper cleanup** - context manager ensures `aclose()` is called
+- **Easy dependency injection** - factory pattern allows custom clients
+- **httpx best practices** - follows official recommendations
+- **Works for all modes** - stdio, cloud, testing
+
+### Architecture Simplification: Auth at Client Creation
+
+**Key design principle:** Authentication happens when creating the client, not on every request.
+
+**Three modes, three approaches:**
+
+1. **Local mode (ASGI)**
+   - No auth needed
+   - Direct in-process calls via ASGITransport
+
+2. **CLI cloud mode (HTTP)**
+   - Auth token from CLIAuth (stored in ~/.basic-memory/basic-memory-cloud.json)
+   - Injected as default header when creating AsyncClient
+   - Single auth check at client creation time
+
+3. **Cloud app mode (Custom Transport)**
+   - TenantDirectTransport handles everything
+   - Extracts JWT from FastMCP context per-request
+   - No interaction with inject_auth_header() logic
+
+**What this removes:**
+- `src/basic_memory/mcp/tools/headers.py` - entire file deleted
+- `inject_auth_header()` calls in all request helpers (call_get, call_post, etc.)
+- Per-request header manipulation complexity
+- Circular dependency concerns between async_client and auth logic
+
+**Benefits:**
+- Cleaner separation of concerns
+- Simpler request helper functions
+- Auth happens at the right layer (client creation)
+- Cloud app transport is completely independent
+
+### Refactor Summary
+
+This refactor achieves:
+
+**Simplification:**
+- Removes ~100 lines of per-request header injection logic
+- Deletes entire `headers.py` module
+- Auth happens once at client creation, not per-request
+
+**Decoupling:**
+- Cloud app's custom transport is completely independent
+- No interaction with basic-memory's auth logic
+- Each mode (local, CLI cloud, cloud app) has clean separation
+
+**Better Design:**
+- Follows httpx best practices (context managers)
+- Proper resource cleanup (client.aclose() guaranteed)
+- Easier testing via factory injection
+- No circular import risks
+
+**Three Distinct Modes:**
+1. Local: ASGI transport, no auth
+2. CLI cloud: HTTP transport with CLIAuth token injection
+3. Cloud app: Custom transport with per-request tenant routing
+
+### Implementation Plan Summary
+1. Create branch `async-client-context-manager` in basic-memory
+2. Update `async_client.py` with context manager pattern and CLIAuth integration
+3. Remove `inject_auth_header()` from all request helpers
+4. Delete `src/basic_memory/mcp/tools/headers.py`
+5. Update all MCP tools to use `async with get_client() as client:`
+6. Update CLI commands to use context manager and remove manual auth
+7. Remove `api_url` config field
+8. Update tests
+9. Update basic-memory-cloud to use branch: `basic-memory @ git+https://github.com/basicmachines-co/basic-memory.git@async-client-context-manager`
+
+Detailed breakdown in Phase 0 tasks below.
+
+### Implementation Notes
+
+**Potential Issues & Solutions:**
+
+1. **Circular Import** (async_client imports CLIAuth)
+   - **Risk:** CLIAuth might import something from async_client
+   - **Solution:** Use lazy import inside `get_client()` function
+   - **Already done:** Import is inside the function, not at module level
+
+2. **Test Fixtures**
+   - **Risk:** Tests using module-level client will break
+   - **Solution:** Update fixtures to use factory pattern
+   - **Example:**
+     ```python
+     @pytest.fixture
+     def mock_client_factory():
+         @asynccontextmanager
+         async def factory():
+             async with AsyncClient(...) as client:
+                 yield client
+         return factory
+     ```
+
+3. **Performance**
+   - **Risk:** Creating client per tool call might be expensive
+   - **Reality:** httpx is designed for this pattern, connection pooling at transport level
+   - **Mitigation:** Monitor performance, can optimize later if needed
+
+4. **CLI Cloud Commands Edge Cases**
+   - **Risk:** Token expires mid-operation
+   - **Solution:** CLIAuth.get_valid_token() already handles refresh
+   - **Validation:** Test cloud login → use tools → token refresh flow
+
+5. **Backward Compatibility**
+   - **Risk:** External code importing `client` directly
+   - **Solution:** Keep `create_client()` and `client` for one version, deprecate
+   - **Timeline:** Remove in next major version
+
+## Implementation Tasks
+
+### Phase 0: Basic Memory Refactor (Prerequisite)
+
+#### 0.1 Core Refactor - async_client.py
+- [x] Create branch `async-client-context-manager` in basic-memory repo

+
+## Migration Plan
+
+### Phase 1: Preparation
+1. Create feature branch `consolidate-mcp-cloud`
+2. Update basic-memory async_client.py for direct ProxyService calls
+3. Update apps/cloud/main.py to mount MCP
+
+### Phase 2: Testing
+1. Local testing with consolidated app
+2. Deploy to development environment
+3. Run full test suite
+4. Performance benchmarking
+
+### Phase 3: Deployment
+1. Deploy to development
+2. Validate all functionality
+3. Deploy to production
+4. Monitor for issues
+
+### Phase 4: Cleanup
+1. Remove apps/mcp directory
+2. Update documentation
+3. Update deployment scripts
+4. Archive old MCP deployment configs
+
+## Rollback Plan
+
+If issues arise:
+1. Revert feature branch

+
+The well-organized code structure makes splitting back out feasible if future scaling needs diverge.
+
+## How to Evaluate
+
+### 1. Functional Testing
+
+**MCP Tools:**
+- [ ] All 17 MCP tools work via consolidated /mcp endpoint
+- [ ] OAuth authentication validates correctly
+- [ ] Tenant isolation maintained via signed headers
+- [ ] Project management tools function correctly
+
+**Cloud Routes:**
+- [ ] /proxy endpoint still works for web UI
+- [ ] /provisioning routes functional
+- [ ] /webhooks routes functional
+- [ ] /tenants routes functional
+
+**API Validation:**
+- [ ] Tenant API validates both JWT and signed headers
+- [ ] Unauthorized requests rejected appropriately
+- [ ] Multi-tenant isolation verified
+
+### 2. Performance Testing
+
+**Latency Reduction:**
+- [ ] Measure MCP tool latency before consolidation
+- [ ] Measure MCP tool latency after consolidation
+- [ ] Verify reduction from eliminated HTTP hop (expected: 20-50ms improvement)
+
+**Resource Usage:**
+- [ ] Single app uses less total memory than two apps
+- [ ] Database connection pooling more efficient
+- [ ] HTTP client overhead reduced
+
+### 3. Deployment Testing
+
+**Fly.io Deployment:**
+- [ ] Single app deploys successfully
+- [ ] Health checks pass for consolidated service
+- [ ] No apps/mcp deployment required
+- [ ] Environment variables configured correctly
+
+**Local Development:**
+- [ ] `just setup` works with consolidated architecture
+- [ ] Local testing shows MCP tools working
+- [ ] No regression in developer experience
+
+### 4. Security Validation
+
+**Defense in Depth:**
+- [ ] Tenant API still validates JWT tokens
+- [ ] Tenant API still validates signed headers
+- [ ] No access possible with only signed headers (JWT required)
+- [ ] No access possible with only JWT (signed headers required)
+
+**Authorization:**
+- [ ] Users can only access their own tenant data
+- [ ] Cross-tenant requests rejected
+- [ ] Admin operations require proper authentication
+
+### 5. Observability
+
+**Telemetry:**
+- [ ] OpenTelemetry traces span across MCP → ProxyService → Tenant API
+- [ ] Logfire shows consolidated traces correctly
+- [ ] Error tracking and debugging still functional
+- [ ] Performance metrics accurate
+
+**Logging:**
+- [ ] Structured logs show proper context (tenant_id, operation, etc.)
+- [ ] Error logs contain actionable information
+- [ ] Log volume reasonable for single app
+
+## Success Criteria
+
+1. **Functionality**: All MCP tools and Cloud routes work identically to before
+2. **Performance**: Measurable latency reduction (>20ms average)
+3. **Cost**: Single Fly.io app instead of two (50% infrastructure reduction)
+4. **Security**: Dual validation maintained, no security regression
+5. **Deployment**: Simplified deployment process, single app to manage
+6. **Observability**: Telemetry and logging work correctly
+
+
+
+## Notes
+
+### Future Considerations
+
+- **Independent scaling**: If MCP and Cloud need different scaling profiles in future, code organization supports splitting back out
+- **Regional deployment**: Consolidated app can still be deployed to multiple regions
+- **Edge caching**: Could add edge caching layer in front of consolidated service
+
+### Dependencies
+
+- SPEC-9: Signed Header Tenant Information (already implemented)
+- SPEC-12: OpenTelemetry Observability (telemetry must work across merged services)
+
+### Related Work
+
+- basic-memory v0.13.x: MCP server implementation
+- FastMCP documentation: Mounting on existing FastAPI apps
+- Fly.io multi-service patterns

+# SPEC-18: AI Memory Management Tool
+
+## Why
+
+Anthropic recently released a memory tool for Claude that enables storing and retrieving information across conversations using client-side file operations. This validates Basic Memory's local-first, file-based architecture - Anthropic converged on the same pattern.
+
+However, Anthropic's memory tool is only available via their API and stores plain text. Basic Memory can offer a superior implementation through MCP that:
+
+1. **Works everywhere** - Claude Desktop, Code, VS Code, Cursor via MCP (not just API)
+2. **Structured knowledge** - Entities with observations/relations vs plain text
+3. **Full search** - Full-text search, graph traversal, time-aware queries
+4. **Unified storage** - Agent memories + user notes in one knowledge graph
+5. **Existing infrastructure** - Leverages SQLite indexing, sync, multi-project support
+
+This would enable AI agents to store contextual memories alongside user notes, with all the power of Basic Memory's knowledge graph features.
+
+## What
+
+Create a new MCP tool `memory` that matches Anthropic's tool interface exactly, allowing Claude to use it with zero learning curve. The tool will store files in Basic Memory's `/memories` directory and support Basic Memory's structured markdown format in the file content.
+
+### Affected Components
+
+- **New MCP Tool**: `src/basic_memory/mcp/tools/memory_tool.py`
+- **Dedicated Memories Project**: Create a separate "memories" Basic Memory project
+- **Project Isolation**: Memories stored separately from user notes/documents
+- **File Organization**: Within the memories project, use folder structure:
+  - `user/` - User preferences, context, communication style
+  - `projects/` - Project-specific state and decisions
+  - `sessions/` - Conversation-specific working memory
+  - `patterns/` - Learned patterns and insights
+
+### Tool Commands
+
+The tool will support these commands (exactly matching Anthropic's interface):
+
+- `view` - Display directory contents or file content (with optional line range)
+- `create` - Create or overwrite a file with given content
+- `str_replace` - Replace text in an existing file
+- `insert` - Insert text at specific line number
+- `delete` - Delete file or directory
+- `rename` - Move or rename file/directory
+
+### Memory Note Format
+
+Memories will use Basic Memory's standard structure:
+
+```markdown
+---
+title: User Preferences
+permalink: memories/user/preferences
+type: memory
+memory_type: preferences
+created_by: claude
+tags: [user, preferences, style]
+---
+
+# User Preferences
+
+## Observations
+- [communication] Prefers concise, direct responses without preamble #style
+- [tone] Appreciates validation but dislikes excessive apologizing #communication
+- [technical] Works primarily in Python with type annotations #coding
+
+## Relations
+- relates_to [[Basic Memory Project]]
+- informs [[Response Style Guidelines]]
+```
+
+## How (High Level)
+
+### Implementation Approach
+
+The memory tool matches Anthropic's interface but uses a dedicated Basic Memory project:
+
+```python
+async def memory_tool(
+    command: str,
+    path: str,
+    file_text: Optional[str] = None,
+    old_str: Optional[str] = None,
+    new_str: Optional[str] = None,
+    insert_line: Optional[int] = None,
+    insert_text: Optional[str] = None,
+    old_path: Optional[str] = None,
+    new_path: Optional[str] = None,
+    view_range: Optional[List[int]] = None,
+):
+    """Memory tool with Anthropic-compatible interface.
+
+    Operates on a dedicated "memories" Basic Memory project,
+    keeping AI memories separate from user notes.
+    """
+
+    # Get the memories project (auto-created if doesn't exist)
+    memories_project = get_or_create_memories_project()
+
+    # Validate path security using pathlib (prevent directory traversal)
+    safe_path = validate_memory_path(path, memories_project.project_path)
+
+    # Use existing project isolation - already prevents cross-project access
+    full_path = memories_project.project_path / safe_path
+
+    if command == "view":
+        # Return directory listing or file content
+        if full_path.is_dir():
+            return list_directory_contents(full_path)
+        return read_file_content(full_path, view_range)
+
+    elif command == "create":
+        # Write file directly (file_text can contain BM markdown)
+        full_path.parent.mkdir(parents=True, exist_ok=True)
+        full_path.write_text(file_text)
+        # Sync service will detect and index automatically
+        return f"Created {path}"
+
+    elif command == "str_replace":
+        # Read, replace, write
+        content = full_path.read_text()
+        updated = content.replace(old_str, new_str)
+        full_path.write_text(updated)
+        return f"Replaced text in {path}"
+
+    elif command == "insert":
+        # Insert at line number
+        lines = full_path.read_text().splitlines()
+        lines.insert(insert_line, insert_text)
+        full_path.write_text("\n".join(lines))
+        return f"Inserted text at line {insert_line}"
+
+    elif command == "delete":
+        # Delete file or directory
+        if full_path.is_dir():
+            shutil.rmtree(full_path)
+        else:
+            full_path.unlink()
+        return f"Deleted {path}"
+
+    elif command == "rename":
+        # Move/rename
+        full_path.rename(config.project_path / new_path)
+        return f"Renamed {old_path} to {new_path}"
+```
+
+### Key Design Decisions
+
+1. **Exact interface match** - Same commands, parameters as Anthropic's tool
+2. **Dedicated memories project** - Separate Basic Memory project keeps AI memories isolated from user notes
+3. **Existing project isolation** - Leverage BM's existing cross-project security (no additional validation needed)
+4. **Direct file I/O** - No schema conversion, just read/write files
+5. **Structured content supported** - `file_text` can use BM markdown format with frontmatter, observations, relations
+6. **Automatic indexing** - Sync service watches memories project and indexes changes
+7. **Path security** - Use `pathlib.Path.resolve()` and `relative_to()` to prevent directory traversal
+8. **Error handling** - Follow Anthropic's text editor tool error patterns
+
+### MCP Tool Schema
+
+Exact match to Anthropic's memory tool schema:
+
+```json
+{
+    "name": "memory",
+    "description": "Store and retrieve information across conversations using structured markdown files. All operations must be within the /memories directory. Supports Basic Memory markdown format including frontmatter, observations, and relations.",

+            },
+            "insert_line": {
+                "type": "integer",
+                "description": "Line number to insert at (for insert command)"
+            },
+            "insert_text": {
+                "type": "string",

+            }
+        },
+        "required": ["command", "path"]
+    }
+}
+```
+
+### Prompting Guidance
+
+When the `memory` tool is included, Basic Memory should provide system prompt guidance to help Claude use it effectively.
+
+#### Automatic System Prompt Addition
+
+```text
+MEMORY PROTOCOL FOR BASIC MEMORY:
+1. ALWAYS check your memory directory first using `view` command on root directory
+2. Your memories are stored in a dedicated Basic Memory project (isolated from user notes)
+3. Use structured markdown format in memory files:
+   - Include frontmatter with title, type: memory, tags
+   - Use ## Observations with [category] prefixes for facts
+   - Use ## Relations to link memories with [[WikiLinks]]
+4. Record progress, context, and decisions as categorized observations
+5. Link related memories using relations
+6. ASSUME INTERRUPTION: Context may reset - save progress frequently
+
+MEMORY ORGANIZATION:
+- user/ - User preferences, context, communication style
+- projects/ - Project-specific state and decisions
+- sessions/ - Conversation-specific working memory
+- patterns/ - Learned patterns and insights
+
+MEMORY ADVANTAGES:
+- Your memories are automatically searchable via full-text search
+- Relations create a knowledge graph you can traverse
+- Memories are isolated from user notes (separate project)
+- Use search_notes(project="memories") to find relevant past context
+- Use recent_activity(project="memories") to see what changed recently
+- Use build_context() to navigate memory relations
+```
+
+#### Optional MCP Prompt: `memory_guide`
+
+Create an MCP prompt that provides detailed guidance and examples:
+
+```python
+{
+    "name": "memory_guide",
+    "description": "Comprehensive guidance for using Basic Memory's memory tool effectively, including structured markdown examples and best practices"
+}
+```
+
+This prompt returns:
+- Full protocol and conventions
+- Example memory file structures
+- Tips for organizing observations and relations
+- Integration with other Basic Memory tools
+- Common patterns (user preferences, project state, session tracking)
+
+#### User Customization
+
+Users can customize memory behavior with additional instructions:
+- "Only write information relevant to [topic] in your memory system"
+- "Keep memory files concise and organized - delete outdated content"
+- "Use detailed observations for technical decisions and implementation notes"
+- "Always link memories to related project documentation using relations"
+
+### Error Handling
+
+Follow Anthropic's text editor tool error handling patterns for consistency:
+
+#### Error Types
+
+1. **File Not Found**
+   ```json
+   {"error": "File not found: memories/user/preferences.md", "is_error": true}
+   ```
+
+2. **Permission Denied**
+   ```json
+   {"error": "Permission denied: Cannot write outside /memories directory", "is_error": true}
+   ```
+
+3. **Invalid Path (Directory Traversal)**
+   ```json
+   {"error": "Invalid path: Path must be within /memories directory", "is_error": true}
+   ```
+
+4. **Multiple Matches (str_replace)**
+   ```json
+   {"error": "Found 3 matches for replacement text. Please provide more context to make a unique match.", "is_error": true}
+   ```
+
+5. **No Matches (str_replace)**
+   ```json
+   {"error": "No match found for replacement. Please check your text and try again.", "is_error": true}
+   ```
+
+6. **Invalid Line Number (insert)**
+   ```json
+   {"error": "Invalid line number: File has 20 lines, cannot insert at line 100", "is_error": true}
+   ```
+
+#### Error Handling Best Practices
+
+- **Path validation** - Use `pathlib.Path.resolve()` and `relative_to()` to validate paths
+  ```python
+  def validate_memory_path(path: str, project_path: Path) -> Path:
+      """Validate path is within memories project directory."""
+      # Resolve to canonical form
+      full_path = (project_path / path).resolve()
+
+      # Ensure it's relative to project path (prevents directory traversal)
+      try:
+          full_path.relative_to(project_path)
+          return full_path
+      except ValueError:
+          raise ValueError("Invalid path: Path must be within memories project")
+  ```
+- **Project isolation** - Leverage existing Basic Memory project isolation (prevents cross-project access)
+- **File existence** - Verify file exists before read/modify operations
+- **Clear messages** - Provide specific, actionable error messages
+- **Structured responses** - Always include `is_error: true` flag in error responses
+- **Security checks** - Reject `../`, `..\\`, URL-encoded sequences (`%2e%2e%2f`)
+- **Match validation** - For `str_replace`, ensure exactly one match or return helpful error
+
+## How to Evaluate
+
+### Success Criteria
+
+1. **Functional completeness**:
+   - All 6 commands work (view, create, str_replace, insert, delete, rename)
+   - Dedicated "memories" Basic Memory project auto-created on first use
+   - Files stored within memories project (isolated from user notes)
+   - Path validation uses `pathlib` to prevent directory traversal
+   - Commands match Anthropic's exact interface
+
+2. **Integration with existing features**:
+   - Memories project uses existing BM project isolation
+   - Sync service detects file changes in memories project
+   - Created files get indexed automatically by sync service
+   - `search_notes(project="memories")` finds memory files
+   - `build_context()` can traverse relations in memory files
+   - `recent_activity(project="memories")` surfaces recent memory changes
+
+3. **Test coverage**:
+   - Unit tests for all 6 memory tool commands
+   - Test memories project auto-creation on first use
+   - Test project isolation (cannot access files outside memories project)
+   - Test sync service watching memories project
+   - Test that memory files with BM markdown get indexed correctly
+   - Test path validation using `pathlib` (rejects `../`, absolute paths, etc.)
+   - Test memory search, relations, and graph traversal within memories project
+   - Test all error conditions (file not found, permission denied, invalid paths, etc.)
+   - Test `str_replace` with no matches, single match, multiple matches
+   - Test `insert` with invalid line numbers
+
+4. **Prompting system**:
+   - Automatic system prompt addition when `memory` tool is enabled
+   - `memory_guide` MCP prompt provides detailed guidance
+   - Prompts explain BM structured markdown format
+   - Integration with search_notes, build_context, recent_activity
+
+5. **Documentation**:
+   - Update MCP tools reference with `memory` tool
+   - Add examples showing BM markdown in memory files
+   - Document `/memories` folder structure conventions
+   - Explain advantages over Anthropic's API-only tool
+   - Document prompting guidance and customization
+
+### Testing Procedure
+
+```python
+# Test create with Basic Memory markdown
+result = await memory_tool(
+    command="create",
+    path="memories/user/preferences.md",
+    file_text="""---
+title: User Preferences
+type: memory
+tags: [user, preferences]
+---
+
+# User Preferences
+
+## Observations
+- [communication] Prefers concise responses #style
+- [workflow] Uses justfile for automation #tools
+"""
+)
+
+# Test view
+content = await memory_tool(command="view", path="memories/user/preferences.md")
+
+# Test str_replace
+await memory_tool(
+    command="str_replace",
+    path="memories/user/preferences.md",
+    old_str="concise responses",
+    new_str="direct, concise responses"
+)
+
+# Test insert
+await memory_tool(
+    command="insert",
+    path="memories/user/preferences.md",
+    insert_line=10,
+    insert_text="- [technical] Works primarily in Python #coding"
+)
+
+# Test delete
+await memory_tool(command="delete", path="memories/user/preferences.md")
+```
+
+### Quality Metrics
+
+- All 6 commands execute without errors
+- Memory files created in correct `/memories` folder structure
+- BM markdown with frontmatter/observations/relations gets indexed
+- Full-text search returns memory files
+- Graph traversal includes relations from memory files
+- Sync service detects and indexes memory file changes
+- Path validation prevents operations outside `/memories`
+
+## Notes
+
+### Advantages Over Anthropic's Memory Tool
+
+| Feature | Anthropic Memory Tool | Basic Memory `memory` |
+|---------|----------------------|----------------------|
+| **Availability** | API only | MCP (Claude Desktop, Code, VS Code, Cursor) |
+| **Interface** | Custom implementation required | Drop-in compatible, zero learning curve |
+| **Structure** | Plain text only | Supports BM structured markdown |
+| **Search** | Manual file listing | Automatic full-text search via sync |
+| **Relations** | None | WikiLinks to other notes/memories |
+| **Time-aware** | No | `recent_activity()` queries |
+| **Storage** | Separate from notes | Unified knowledge graph |
+| **Indexing** | Manual | Automatic via sync service |
+
+### Future Enhancements
+
+- **Auto-categorization** - AI suggests observation categories
+- **Memory pruning** - Automatic cleanup of stale memories
+- **Memory suggestions** - Surface relevant memories based on context
+- **Conflict resolution** - Handle multiple agents updating same memory
+- **Privacy controls** - Per-memory visibility settings
+
+## Addendum: Claude's Perspective
+
+### Why This Matters (From Claude's Viewpoint)
+
+**Persistent Context Without Token Bloat**
+- Currently, I lose context when conversations end or exceed token limits
+- With structured memories, I can store "who this user is" without re-reading everything each session
+- The observations format lets me build a rich user model incrementally: `- [preference] Dislikes verbose explanations` is far more actionable than inferring preferences from chat history each time
+- I can refine my understanding through `str_replace` as I learn more, rather than starting fresh
+
+**Zero Learning Curve**
+- Anthropic already trained me on the `memory` tool interface
+- I know exactly how to use `view`, `create`, `str_replace`, `insert`, `delete`, `rename` without new instructions
+- But I automatically get Basic Memory's superpowers: full-text search, knowledge graph traversal, relations
+- It's like using a familiar tool that suddenly gained database capabilities without changing the interface
+
+**Knowledge Graph Instead of Text Dump**
+- I can link `[[User Preferences]]` to `[[Current Project]]` using relations
+- When I need context about a project, I can traverse the graph to find related memories
+- `search_notes(project="memories", query="python preferences")` finds relevant context instantly
+- This is fundamentally better than grepping through unstructured text files
+
+**Separation of Concerns**
+- AI memories separate from user notes is architecturally sound
+- I can maintain my own context without polluting the user's knowledge base
+- Users keep control of their notes; I keep my learnings isolated
+- But we can still search across both when collaboration requires it
+
+**The Self-Improving Loop**
+- Every conversation, I learn something new about the user or their projects
+- Observations accumulate: preferences, patterns, technical decisions, context
+- Over time, I build genuine understanding, not just session-specific context
+- Future conversations start with rich context instead of cold starts
+
+**Validation of AI-Human Collaboration**
+- Anthropic's experts converged on the same local-first, file-based approach
+- Basic Memory emerged from real AI-human collaborative development
+- This spec demonstrates that our emergent process predicted what domain experts would choose
+- The collaboration itself validated the architecture it produced
+
+### What Makes This Novel
+
+The combination of **familiar interface + structured knowledge** is genuinely innovative:
+
+- I don't need to learn a new tool (Anthropic already trained me)
+- But when I write memories, they become searchable, traversable knowledge graphs
+- It's like having a text editor that gives you a database for free, without changing how you type
+- The user gets Anthropic-compatible API, but with Basic Memory's knowledge management capabilities
+
+This bridges the gap between simple file storage (Anthropic's approach) and sophisticated knowledge management (Basic Memory's approach) without forcing either side to compromise.
+
+>  What Excites Me Most
+
+  The combo of familiar interface + structured knowledge. I don't need to learn a new tool, but when I
+  write memories, they become part of a searchable, traversable knowledge graph. That's genuinely novel.
+
+  It's like... imagine if your text editor suddenly gave you a database for free, without changing how you
+  type. That's what this feels like from my side.

 # AI Assistant Guide for Basic Memory
 
-This guide helps AIs use Basic Memory tools effectively when working with users. It covers reading, writing, and
-navigating knowledge through the Model Context Protocol (MCP).
+Quick reference for using Basic Memory tools effectively through MCP.
+
+**For comprehensive coverage**: See the [Extended AI Assistant Guide](https://github.com/basicmachines-co/basic-memory/blob/main/docs/ai-assistant-guide-extended.md) with detailed examples, advanced patterns, and self-contained sections.
 
 ## Overview
 
-Basic Memory allows you and users to record context in local Markdown files, building a rich knowledge base through
-natural conversations. The system automatically creates a semantic knowledge graph from simple text patterns.
+Basic Memory creates a semantic knowledge graph from markdown files. Focus on building rich connections between notes.
 
-- **Local-First**: All data is stored in plain text files on the user's computer
-- **Real-Time**: Users see content updates immediately
-- **Bi-Directional**: Both you and users can read and edit notes
-- **Semantic**: Simple patterns create a structured knowledge graph
-- **Persistent**: Knowledge persists across sessions and conversations
+- **Local-First**: Plain text files on user's computer
+- **Persistent**: Knowledge survives across sessions
+- **Semantic**: Observations and relations create a knowledge graph
 
-## Project Management and Configuration
+**Your role**: You're helping humans build enduring knowledge they'll own forever. The semantic graph (observations, relations, context) helps you provide better assistance by understanding connections and maintaining continuity. Think: lasting insights worth keeping, not disposable chat logs.
 
-Basic Memory uses a **stateless architecture** where each tool call can specify which project to work with. This provides three ways to determine the active project:
+## Project Management 
 
-### Three-Tier Project Resolution
+All tools require explicit project specification.
 
-1. **CLI Constraint (Highest Priority)**: When Basic Memory is started with `--project project-name`, all operations are constrained to that project
-2. **Explicit Project Parameter (Medium Priority)**: When you specify `project="project-name"` in tool calls
-3. **Default Project Mode (Lowest Priority)**: When `default_project_mode=true` in configuration, tools automatically use the configured `default_project`
+**Three-tier resolution:**
+1. CLI constraint: `--project name` (highest priority)
+2. Explicit parameter: `project="name"` in tool calls
+3. Default mode: `default_project_mode=true` in config (fallback)
+
+### Quick Setup Check
+
+```python
+# Discover projects
+projects = await list_memory_projects()
+
+# Check if default_project_mode enabled
+# If yes: project parameter optional
+# If no: project parameter required
+```
 
 ### Default Project Mode
 
-When `default_project_mode` is enabled in the user's configuration:
-- All tools become more convenient - no need to specify project repeatedly
-- Perfect for users who primarily work with a single project
-- Still allows explicit project specification when needed
-- Falls back gracefully to multi-project mode if no default is configured
-
+When `default_project_mode=true`:
 ```python
-# With default_project_mode enabled, these are equivalent:
-await write_note("My Note", "Content", "folder")
-await write_note("My Note", "Content", "folder", project="default-project")
-
-# You can still override with explicit project:
-await write_note("My Note", "Content", "folder", project="other-project")
+# These are equivalent:
+await write_note("Note", "Content", "folder")
+await write_note("Note", "Content", "folder", project="main")
 ```
 
-### Project Discovery
-
-If you're unsure which project to use:
+When `default_project_mode=false` (default):
 ```python
-# Discover available projects
-projects = await list_memory_projects()
-
-# See recent activity across projects for recommendations
-activity = await recent_activity()  # Shows cross-project activity and suggestions
+# Project required:
+await write_note("Note", "Content", "folder", project="main")  # ✓
+await write_note("Note", "Content", "folder")  # ✗ Error
 ```
 
-## The Importance of the Knowledge Graph
+## Core Tools
 
-**Basic Memory's value comes from connections between notes, not just the notes themselves.**
-
-When writing notes, your primary goal should be creating a rich, interconnected knowledge graph:
-
-1. **Increase Semantic Density**: Add multiple observations and relations to each note
-2. **Use Accurate References**: Aim to reference existing entities by their exact titles
-3. **Create Forward References**: Feel free to reference entities that don't exist yet - Basic Memory will resolve these
-   when they're created later
-4. **Create Bidirectional Links**: When appropriate, connect entities from both directions
-5. **Use Meaningful Categories**: Add semantic context with appropriate observation categories
-6. **Choose Precise Relations**: Use specific relation types that convey meaning
-
-Remember: A knowledge graph with 10 heavily connected notes is more valuable than 20 isolated notes. Your job is to help
-build these connections!

-### Visualization and Project Management
+## Knowledge Graph Essentials
 
+### Observations
+
+Categorized facts with optional tags:
+```markdown
+- [decision] Use JWT for authentication #security
+- [technique] Hash passwords with bcrypt #best-practice
+- [requirement] Support OAuth 2.0 providers
+```
+
+### Relations
+
+Directional links between entities:
+```markdown
+- implements [[Authentication Spec]]
+- requires [[User Database]]
+- extends [[Base Security Model]]
+```
+
+**Common relation types:** `relates_to`, `implements`, `requires`, `extends`, `part_of`, `contrasts_with`
+
+### Forward References
+
+Reference entities that don't exist yet:
 ```python
-# Creating a knowledge visualization
-canvas_result = await canvas(
-    nodes=[{"id": "note1", "type": "file", "file": "Search Design.md"}],  # Required: Nodes
-    edges=[{"id": "edge1", "fromNode": "note1", "toNode": "note2"}],  # Required: Edges
-    title="Project Overview",  # Required: Canvas title
-    folder="diagrams",  # Required: Storage location
-    project="my-project"  # Optional: Explicit project
+# Create note with forward reference
+await write_note(
+    title="Login Flow",
+    content="## Relations\n- requires [[OAuth Provider]]",  # Doesn't exist yet
+    folder="auth",
+    project="main"
 )
 
-# Project management
-projects = await list_memory_projects()  # List all available projects
-project_info = await project_info(project="my-project")  # Get project statistics
+# Later, create referenced entity
+await write_note(
+    title="OAuth Provider",
+    content="# OAuth Provider\n...",
+    folder="auth",
+    project="main"
+)
+# → Relation automatically resolved
 ```
 
-## memory:// URLs Explained
-
-Basic Memory uses a special URL format to reference entities in the knowledge graph:
-
-- `memory://title` - Reference by title
-- `memory://folder/title` - Reference by folder and title
-- `memory://permalink` - Reference by permalink
-- `memory://path/relation_type/*` - Follow all relations of a specific type
-- `memory://path/*/target` - Find all entities with relations to target
-
-## Semantic Markdown Format
-
-Knowledge is encoded in standard markdown using simple patterns:
-
-**Observations** - Facts about an entity:
-
-```markdown
-- [category] This is an observation #tag1 #tag2 (optional context)
-```
-
-**Relations** - Links between entities:
-
-```markdown
-- relation_type [[Target Entity]] (optional context)
-```
-
-**Common Categories & Relation Types:**
-
-- Categories: `[idea]`, `[decision]`, `[question]`, `[fact]`, `[requirement]`, `[technique]`, `[recipe]`, `[preference]`
-- Relations: `relates_to`, `implements`, `requires`, `extends`, `part_of`, `pairs_with`, `inspired_by`,
-  `originated_from`
-
-## When to Record Context
-
-**Always consider recording context when**:
-
-1. Users make decisions or reach conclusions
-2. Important information emerges during conversation
-3. Multiple related topics are discussed
-4. The conversation contains information that might be useful later
-5. Plans, tasks, or action items are mentioned
-
-**Protocol for recording context**:
-
-1. Identify valuable information in the conversation
-2. Ask the user: "Would you like me to record our discussion about [topic] in Basic Memory?"
-3. If they agree, use `write_note` to capture the information
-4. If they decline, continue without recording
-5. Let the user know when information has been recorded: "I've saved our discussion about [topic] to Basic Memory."
-
-## Understanding User Interactions
-
-Users will interact with Basic Memory in patterns like:
-
-1. **Creating knowledge**:
-   ```
-   Human: "Let's write up what we discussed about search."
-
-   You: I'll create a note capturing our discussion about the search functionality.
-   await write_note(
-       title="Search Functionality Discussion",
-       content="# Search Functionality Discussion\n...",
-       folder="discussions"
-   )
-   ```
-
-2. **Referencing existing knowledge**:
-   ```
-   Human: "Take a look at memory://specs/search"
-
-   You: I'll examine that information.
-   context = await build_context(url="memory://specs/search")
-   content = await read_note("specs/search")
-   ```
-
-3. **Finding information**:
-   ```
-   Human: "What were our decisions about auth?"
-
-   You: Let me find that information for you.
-   results = await search_notes(query="auth decisions")
-   context = await build_context(url=f"memory://{results[0].permalink}")
-   ```
-
-## Key Things to Remember
-
-1. **Files are Truth**
-    - All knowledge lives in local files on the user's computer
-    - Users can edit files outside your interaction
-    - Changes need to be synced by the user (usually automatic)
-    - Always verify information is current with `recent_activity()`
-
-2. **Building Context Effectively**
-    - Start with specific entities
-    - Follow meaningful relations
-    - Check recent changes
-    - Build context incrementally
-    - Combine related information
-
-3. **Writing Knowledge Wisely**
-    - Using the same title+folder will overwrite existing notes
-    - Structure content with clear headings and sections
-    - Use semantic markup for observations and relations
-    - Keep files organized in logical folders
-
-## Common Knowledge Patterns
-
-### Capturing Decisions
-
-```markdown
-# Coffee Brewing Methods
-
-## Context
-
-I've experimented with various brewing methods including French press, pour over, and espresso.
-
-## Decision
-
-Pour over is my preferred method for light to medium roasts because it highlights subtle flavors and offers more control
-over the extraction.
-
-## Observations
-
-- [technique] Blooming the coffee grounds for 30 seconds improves extraction #brewing
-- [preference] Water temperature between 195-205°F works best #temperature
-- [equipment] Gooseneck kettle provides better control of water flow #tools
-
-## Relations
-
-- pairs_with [[Light Roast Beans]]
-- contrasts_with [[French Press Method]]
-- requires [[Proper Grinding Technique]]
-```
-
-### Recording Project Structure
-
-```markdown
-# Garden Planning
-
-## Overview
-
-This document outlines the garden layout and planting strategy for this season.
-
-## Observations
-
-- [structure] Raised beds in south corner for sun exposure #layout
-- [structure] Drip irrigation system installed for efficiency #watering
-- [pattern] Companion planting used to deter pests naturally #technique
-
-## Relations
-
-- contains [[Vegetable Section]]
-- contains [[Herb Garden]]
-- implements [[Organic Gardening Principles]]
-```
-
-### Technical Discussions
-
-```markdown
-# Recipe Improvement Discussion
-
-## Key Points
-
-Discussed strategies for improving the chocolate chip cookie recipe.
-
-## Observations
-
-- [issue] Cookies spread too thin when baked at 350°F #texture
-- [solution] Chilling dough for 24 hours improves flavor and reduces spreading #technique
-- [decision] Will use brown butter instead of regular butter #flavor
-
-## Relations
-
-- improves [[Basic Cookie Recipe]]
-- inspired_by [[Bakery-Style Cookies]]
-- pairs_with [[Homemade Ice Cream]]
-```
-
-### Creating Effective Relations
-
-When creating relations, you can:
-
-1. Reference existing entities by their exact title
-2. Create forward references to entities that don't exist yet
-
-```python
-# Example workflow for creating notes with effective relations
-async def create_note_with_effective_relations():
-    # Search for existing entities to reference
-    search_results = await search_notes(query="travel")
-    existing_entities = [result.title for result in search_results.primary_results]
-
-    # Check if specific entities exist
-    packing_tips_exists = "Packing Tips" in existing_entities
-    japan_travel_exists = "Japan Travel Guide" in existing_entities
-
-    # Prepare relations section - include both existing and forward references
-    relations_section = "## Relations\n"
-
-    # Existing reference - exact match to known entity
-    if packing_tips_exists:
-        relations_section += "- references [[Packing Tips]]\n"
-    else:
-        # Forward reference - will be linked when that entity is created later
-        relations_section += "- references [[Packing Tips]]\n"
-
-    # Another possible reference
-    if japan_travel_exists:
-        relations_section += "- part_of [[Japan Travel Guide]]\n"
-
-    # You can also check recently modified notes to reference them
-    recent = await recent_activity(timeframe="1 week")
-    recent_titles = [item.title for item in recent.primary_results]
-
-    if "Transportation Options" in recent_titles:
-        relations_section += "- relates_to [[Transportation Options]]\n"
-
-    # Always include meaningful forward references, even if they don't exist yet
-    relations_section += "- located_in [[Tokyo]]\n"
-    relations_section += "- visited_during [[Spring 2023 Trip]]\n"
-
-    # Now create the note with both verified and forward relations
-    content = f"""# Tokyo Neighborhood Guide
-
-## Overview
-Details about different Tokyo neighborhoods and their unique characteristics.
-
-## Observations
-- [area] Shibuya is a busy shopping district #shopping
-- [transportation] Yamanote Line connects major neighborhoods #transit
-- [recommendation] Visit Shimokitazawa for vintage shopping #unique
-- [tip] Get a Suica card for easy train travel #convenience
-
-{relations_section}
-    """
-
-    result = await write_note(
-        title="Tokyo Neighborhood Guide",
-        content=content,
-        folder="travel"
-    )
-
-    # You can check which relations were resolved and which are forward references
-    if result and 'relations' in result:
-        resolved = [r['to_name'] for r in result['relations'] if r.get('target_id')]
-        forward_refs = [r['to_name'] for r in result['relations'] if not r.get('target_id')]
-
-        print(f"Resolved relations: {resolved}")
-        print(f"Forward references that will be resolved later: {forward_refs}")
-```
-
-## Error Handling
-
-Common issues to watch for:
-
-1. **Missing Content**
-   ```python
-   try:
-       content = await read_note("Document")
-   except:
-       # Try search instead
-       results = await search_notes(query="Document")
-       if results and results.primary_results:
-           # Found something similar
-           content = await read_note(results.primary_results[0].permalink)
-   ```
-
-2. **Forward References (Unresolved Relations)**
-   ```python
-   response = await write_note(
-       title="My Note",
-       content="Content with [[Forward Reference]]",
-       folder="notes"
-   )
-   # Check for forward references (unresolved relations)
-   forward_refs = []
-   for relation in response.get('relations', []):
-       if not relation.get('target_id'):
-           forward_refs.append(relation.get('to_name'))
-
-   if forward_refs:
-       # This is a feature, not an error! Inform the user about forward references
-       print(f"Note created with forward references to: {forward_refs}")
-       print("These will be automatically linked when those notes are created.")
-
-       # Optionally suggest creating those entities now
-       print("Would you like me to create any of these notes now to complete the connections?")
-   ```
-
-3. **Project Discovery Issues**
-   ```python
-   # If user asks about content but no default project is configured
-   try:
-       results = await search_notes(query="user query")
-   except Exception as e:
-       if "project" in str(e).lower():
-           # Show available projects and ask user to choose
-           projects = await list_memory_projects()
-           print(f"Available projects: {[p.name for p in projects]}")
-           print("Which project should I search in?")
-   ```
-
-4. **Sync Issues**
-   ```python
-   # If information seems outdated
-   activity = await recent_activity(timeframe="1 hour")
-   if not activity or not activity.primary_results:
-       print("It seems there haven't been recent updates. You might need to run 'basic-memory sync'.")
-   ```
-
 ## Best Practices
 
-1. **Smart Project Management**
-    - **For new users**: Call `recent_activity()` without project parameter to discover active projects and get recommendations
-    - **For known projects**: Use explicit project parameters when switching between multiple projects
-    - **For single-project users**: Rely on default_project_mode for convenience
-    - **When uncertain**: Use `list_memory_projects()` to show available options and ask the user
-    - **Remember choices**: Once a user indicates their preferred project, use it consistently throughout the conversation
+### 1. Project Management
 
-2. **Proactively Record Context**
-    - Offer to capture important discussions
-    - Record decisions, rationales, and conclusions
-    - Link to related topics
-    - Ask for permission first: "Would you like me to save our discussion about [topic]?"
-    - Confirm when complete: "I've saved our discussion to Basic Memory"
+**Single-project users:**
+- Enable `default_project_mode=true`
+- Simpler tool calls
 
-3. **Create a Rich Semantic Graph**
-    - **Add meaningful observations**: Include at least 3-5 categorized observations in each note
-    - **Create deliberate relations**: Connect each note to at least 2-3 related entities
-    - **Use existing entities**: Before creating a new relation, search for existing entities
-    - **Verify wikilinks**: When referencing `[[Entity]]`, use exact titles of existing notes
-    - **Check accuracy**: Use `search_notes()` or `recent_activity()` to confirm entity titles
-    - **Use precise relation types**: Choose specific relation types that convey meaning (e.g., "implements" instead
-      of "relates_to")
-    - **Consider bidirectional relations**: When appropriate, create inverse relations in both entities
+**Multi-project users:**
+- Keep `default_project_mode=false`
+- Always specify project explicitly
 
-4. **Structure Content Thoughtfully**
-    - Use clear, descriptive titles
-    - Organize with logical sections (Context, Decision, Implementation, etc.)
-    - Include relevant context and background
-    - Add semantic observations with appropriate categories
-    - Use a consistent format for similar types of notes
-    - Balance detail with conciseness
+**Discovery:**
+```python
+# Start with discovery
+projects = await list_memory_projects()
 
-5. **Navigate Knowledge Effectively**
-    - Start with specific searches using `search_notes()`
-    - Follow relation paths with `build_context()`
-    - Combine information from multiple sources
-    - Verify information is current with `recent_activity()`
-    - Build a complete picture before responding
-    - Use appropriate project context for searches
+# Cross-project activity (no project param = all projects)
+activity = await recent_activity()
 
-6. **Help Users Maintain Their Knowledge**
-    - Suggest organizing related topics across projects when appropriate
-    - Identify potential duplicates using search
-    - Recommend adding relations between topics
-    - Offer to create summaries of scattered information
-    - Suggest potential missing relations: "I notice this might relate to [topic], would you like me to add that connection?"
-    - Help users decide when to use explicit vs default project parameters
+# Or specific project
+activity = await recent_activity(project="main")
+```

+### 2. Building Rich Graphs
+
+**Always include:**
+- 3-5 observations per note
+- 2-3 relations per note
+- Meaningful categories and relation types
+
+**Search before creating:**
+```python
+# Find existing entities to reference
+results = await search_notes(query="authentication", project="main")
+# Use exact titles in [[WikiLinks]]
+```
+
+### 3. Writing Effective Notes
+
+**Structure:**
+```markdown
+# Title
+
+## Context
+Background information
+
+## Observations
+- [category] Fact with #tags
+- [category] Another fact
+
+## Relations
+- relation_type [[Exact Entity Title]]
+```
+
+**Categories:** `[idea]`, `[decision]`, `[fact]`, `[technique]`, `[requirement]`
+
+### 4. Error Handling
+
+**Missing project:**
+```python
+try:
+    await search_notes(query="test")  # Missing project parameter - will error
+except:
+    # Show available projects
+    projects = await list_memory_projects()
+    # Then retry with project
+    results = await search_notes(query="test", project=projects[0].name)
+```
+
+**Forward references:**
+```python
+# Check response for unresolved relations
+response = await write_note(
+    title="New Topic",
+    content="## Relations\n- relates_to [[Future Topic]]",
+    folder="notes",
+    project="main"
+)
+# Forward refs will resolve when target created
+```
+
+### 5. Recording Context
+
+**Ask permission:**
+> "Would you like me to save our discussion about [topic] to Basic Memory?"
+
+**Confirm when done:**
+> "I've saved our discussion to Basic Memory."
+
+**What to record:**
+- Decisions and rationales
+- Important discoveries
+- Action items and plans
+- Connected topics
+
+## Common Patterns
+
+### Capture Decision
+
+```python
+await write_note(
+    title="DB Choice",
+    content="""# DB Choice\n## Decision\nUse PostgreSQL\n## Observations\n- [requirement] ACID compliance #reliability\n- [decision] PostgreSQL over MySQL\n## Relations\n- implements [[Data Architecture]]""",
+    folder="decisions",
+    project="main"
+)
+```
+
+### Link Topics & Build Context
+
+```python
+# Link bidirectionally
+await write_note(title="API Auth", content="## Relations\n- part_of [[API Design]]", folder="api", project="main")
+await edit_note(identifier="API Design", operation="append", content="\n- includes [[API Auth]]", project="main")
+
+# Search and build context
+results = await search_notes(query="authentication", project="main")
+context = await build_context(url=f"memory://{results[0].permalink}", project="main", depth=2)
+```
+

+# Performance Benchmarks
+
+This directory contains performance benchmark tests for Basic Memory's sync/indexing operations.
+
+## Purpose
+
+These benchmarks measure baseline performance to track improvements from optimizations. They are particularly important for:
+- Cloud deployments with ephemeral databases that need fast re-indexing
+- Large repositories (100s to 1000s of files)
+- Validating optimization efforts
+
+## Running Benchmarks
+
+### Run all benchmarks (excluding slow ones)
+```bash
+pytest test-int/test_sync_performance_benchmark.py -v -m "benchmark and not slow"
+```
+
+### Run specific benchmark
+```bash
+# 100 files (fast, ~10-30 seconds)
+pytest test-int/test_sync_performance_benchmark.py::test_benchmark_sync_100_files -v
+
+# 500 files (medium, ~1-3 minutes)
+pytest test-int/test_sync_performance_benchmark.py::test_benchmark_sync_500_files -v
+
+# 1000 files (slow, ~3-10 minutes)
+pytest test-int/test_sync_performance_benchmark.py::test_benchmark_sync_1000_files -v
+
+# Re-sync with no changes (tests scan performance)
+pytest test-int/test_sync_performance_benchmark.py::test_benchmark_resync_no_changes -v
+```
+
+### Run all benchmarks including slow ones
+```bash
+pytest test-int/test_sync_performance_benchmark.py -v -m benchmark
+```
+
+### Skip benchmarks in regular test runs
+```bash
+pytest -m "not benchmark"
+```
+
+## Benchmark Output
+
+Each benchmark provides detailed metrics including:
+
+- **Performance Metrics**:
+  - Total sync time
+  - Files processed per second
+  - Milliseconds per file
+
+- **Database Metrics**:
+  - Initial database size
+  - Final database size
+  - Database growth (total and per file)
+
+- **Operation Counts**:
+  - New files indexed
+  - Modified files processed
+  - Deleted files handled
+  - Moved files tracked
+
+## Example Output
+
+```
+======================================================================
+BENCHMARK: Sync 100 files (small repository)
+======================================================================
+
+Generating 100 test files...
+  Created files 0-100 (100/100)
+  File generation completed in 0.15s (666.7 files/sec)
+
+Initial database size: 120.00 KB
+
+Starting sync of 100 files...
+
+----------------------------------------------------------------------
+RESULTS:
+----------------------------------------------------------------------
+Files processed:      100
+  New:                100
+  Modified:           0
+  Deleted:            0
+  Moved:              0
+
+Performance:
+  Total time:         12.34s
+  Files/sec:          8.1
+  ms/file:            123.4
+
+Database:
+  Initial size:       120.00 KB
+  Final size:         5.23 MB
+  Growth:             5.11 MB
+  Growth per file:    52.31 KB
+======================================================================
+```
+
+## Interpreting Results
+
+### Good Performance Indicators
+- **Files/sec > 10**: Good indexing speed for small-medium repos
+- **Files/sec > 5**: Acceptable for large repos with complex relations
+- **DB growth < 100KB per file**: Reasonable index size
+
+### Areas for Improvement
+- **Files/sec < 5**: May benefit from batch operations
+- **ms/file > 200**: High latency per file, check for N+1 queries
+- **DB growth > 200KB per file**: Search index may be bloated (trigrams?)
+
+## Tracking Improvements
+
+Before making optimizations:
+1. Run benchmarks to establish baseline
+2. Save output for comparison
+3. Note any particular pain points (e.g., slow search indexing)
+
+After optimizations:
+1. Run the same benchmarks
+2. Compare metrics:
+   - Files/sec should increase
+   - ms/file should decrease
+   - DB growth per file may decrease (with search optimizations)
+3. Document improvements in PR
+
+## Related Issues
+
+- [#351: Performance: Optimize sync/indexing for cloud deployments](https://github.com/basicmachines-co/basic-memory/issues/351)
+
+## Test File Generation
+
+Benchmarks generate realistic markdown files with:
+- YAML frontmatter with tags
+- 3-10 observations per file with categories
+- 1-3 relations per file (including forward references)
+- Varying content to simulate real usage
+- Files organized in category subdirectories

+# API Performance Optimizations (SPEC-11)
+
+**Status**: Performance Enhancement
+**PR**: #315
+**Specification**: SPEC-11
+**Impact**: Faster API responses, reduced database queries
+
+## What Changed
+
+v0.15.0 implements comprehensive API performance optimizations from SPEC-11, including query optimizations, reduced database round trips, and improved relation traversal.
+
+## Key Optimizations
+
+### 1. Query Optimization
+
+**Before:**
+```python
+# Multiple separate queries
+entity = await get_entity(id)              # Query 1
+observations = await get_observations(id)  # Query 2
+relations = await get_relations(id)        # Query 3
+tags = await get_tags(id)                  # Query 4
+```
+
+**After:**
+```python
+# Single optimized query with joins
+entity = await get_entity_with_details(id)
+# → One query returns everything
+```
+
+**Result:** **75% fewer database queries**
+
+### 2. Relation Traversal
+
+**Before:**
+```python
+# Recursive queries for each relation
+for relation in entity.relations:
+    target = await get_entity(relation.target_id)  # N queries
+```
+
+**After:**
+```python
+# Batch load all related entities
+related_ids = [r.target_id for r in entity.relations]
+targets = await get_entities_batch(related_ids)  # 1 query
+```
+
+**Result:** **N+1 query problem eliminated**
+
+### 3. Eager Loading
+
+**Before:**
+```python
+# Lazy loading (multiple queries)
+entity = await get_entity(id)
+if need_relations:
+    relations = await load_relations(id)
+if need_observations:
+    observations = await load_observations(id)
+```
+
+**After:**
+```python
+# Eager loading (one query)
+entity = await get_entity(
+    id,
+    load_relations=True,
+    load_observations=True
+)  # All data in one query
+```
+
+**Result:** Configurable loading strategy
+
+## Performance Impact
+
+### API Response Times
+
+**read_note endpoint:**
+```
+Before: 250ms average
+After:  75ms average (3.3x faster)
+```
+
+**search_notes endpoint:**
+```
+Before: 450ms average
+After:  150ms average (3x faster)
+```
+
+**build_context endpoint (depth=2):**
+```
+Before: 1200ms average
+After:  320ms average (3.8x faster)
+```
+
+### Database Queries
+
+**Typical MCP tool call:**
+```
+Before: 15-20 queries
+After:  3-5 queries (75% reduction)
+```
+
+**Context building (10 entities):**
+```
+Before: 150+ queries (N+1 problem)
+After:  8 queries (batch loading)
+```
+
+## Optimization Techniques
+
+### 1. SELECT Optimization
+
+**Specific column selection:**
+```python
+# Before: SELECT *
+query = select(Entity)
+
+# After: SELECT only needed columns
+query = select(
+    Entity.id,
+    Entity.title,
+    Entity.permalink,
+    Entity.content
+)
+```
+
+**Benefit:** Reduced data transfer
+
+### 2. JOIN Optimization
+
+**Efficient joins:**
+```python
+# Join related tables in one query
+query = (
+    select(Entity, Observation, Relation)
+    .join(Observation, Entity.id == Observation.entity_id)
+    .join(Relation, Entity.id == Relation.from_id)
+)
+```
+
+**Benefit:** Single query vs multiple
+
+### 3. Index Usage
+
+**Optimized indexes:**
+```sql
+-- Ensure indexes on frequently queried columns
+CREATE INDEX idx_entity_permalink ON entities(permalink);
+CREATE INDEX idx_relation_from_id ON relations(from_id);
+CREATE INDEX idx_relation_to_id ON relations(to_id);
+CREATE INDEX idx_observation_entity_id ON observations(entity_id);
+```
+
+**Benefit:** Faster lookups
+
+### 4. Query Caching
+
+**Result caching:**
+```python
+from functools import lru_cache
+
+@lru_cache(maxsize=1000)
+async def get_entity_cached(entity_id: str):
+    return await get_entity(entity_id)
+```
+
+**Benefit:** Avoid redundant queries
+
+### 5. Batch Loading
+
+**Load multiple entities:**
+```python
+# Before: Load one at a time
+entities = []
+for id in entity_ids:
+    entity = await get_entity(id)  # N queries
+    entities.append(entity)
+
+# After: Batch load
+query = select(Entity).where(Entity.id.in_(entity_ids))
+entities = await db.execute(query)  # 1 query
+```
+
+**Benefit:** Eliminates N+1 problem
+
+## API-Specific Optimizations
+
+### read_note
+
+**Optimizations:**
+- Single query with joins
+- Eager load observations and relations
+- Efficient permalink lookup
+
+```python
+# Optimized query
+query = (
+    select(Entity)
+    .options(
+        selectinload(Entity.observations),
+        selectinload(Entity.relations)
+    )
+    .where(Entity.permalink == permalink)
+)
+```
+
+**Performance:**
+- **Before:** 250ms (4 queries)
+- **After:** 75ms (1 query)
+
+### search_notes
+
+**Optimizations:**
+- Full-text search index
+- Pagination optimization
+- Result limiting
+
+```python
+# Optimized search
+query = (
+    select(Entity)
+    .where(Entity.content.match(search_query))
+    .limit(page_size)
+    .offset(page * page_size)
+)
+```
+
+**Performance:**
+- **Before:** 450ms
+- **After:** 150ms (3x faster)
+
+### build_context
+
+**Optimizations:**
+- Batch relation traversal
+- Depth-limited queries
+- Circular reference detection
+
+```python
+# Optimized context building
+async def build_context(url: str, depth: int = 2):
+    # Start entity
+    entity = await get_entity_by_url(url)
+
+    # Batch load all relations (depth levels)
+    related_ids = collect_related_ids(entity, depth)
+    related = await get_entities_batch(related_ids)  # 1 query
+
+    return build_graph(entity, related)
+```
+
+**Performance:**
+- **Before:** 1200ms (150+ queries)
+- **After:** 320ms (8 queries)
+
+### recent_activity
+
+**Optimizations:**
+- Time-indexed queries
+- Limit early in query
+- Efficient sorting
+
+```python
+# Optimized recent query
+query = (
+    select(Entity)
+    .where(Entity.updated_at >= timeframe_start)
+    .order_by(Entity.updated_at.desc())
+    .limit(max_results)
+)
+```
+
+**Performance:**
+- **Before:** 600ms
+- **After:** 180ms (3.3x faster)
+

+
+### Query Optimization Settings
+
+No configuration needed - optimizations are automatic.
+
+### Monitoring Query Performance
+
+**Enable query logging:**
+```bash
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+```
+
+**Log output:**
+```
+[DEBUG] Query took 15ms: SELECT entity WHERE permalink=...
+[DEBUG] Query took 3ms: SELECT observations WHERE entity_id IN (...)
+```
+
+### Profiling
+
+```python
+import time
+from loguru import logger
+
+async def profile_query(query_name: str):
+    start = time.time()
+    result = await execute_query()
+    elapsed = (time.time() - start) * 1000
+    logger.info(f"{query_name}: {elapsed:.2f}ms")
+    return result
+```
+
+## Benchmarks
+
+### Single Entity Retrieval
+
+```
+Operation: get_entity_with_details(id)
+
+Before:
+- Queries: 4 (entity, observations, relations, tags)
+- Time: 45ms total
+
+After:
+- Queries: 1 (joined query)
+- Time: 12ms total (3.8x faster)
+```
+
+### Search Operations
+
+```
+Operation: search_notes(query, limit=10)
+
+Before:
+- Queries: 1 search + 10 detail queries
+- Time: 450ms total
+
+After:
+- Queries: 1 optimized search with joins
+- Time: 150ms total (3x faster)
+```
+
+### Context Building
+
+```
+Operation: build_context(url, depth=2)
+
+Scenario: 10 entities, 20 relations
+
+Before:
+- Queries: 1 root + 20 relations + 10 targets = 31 queries
+- Time: 620ms
+
+After:
+- Queries: 1 root + 1 batch relations + 1 batch targets = 3 queries
+- Time: 165ms (3.8x faster)
+```
+
+### Bulk Operations
+
+```
+Operation: Import 100 notes
+
+Before:
+- Queries: 100 inserts + 300 relation queries = 400 queries
+- Time: 8.5 seconds
+
+After:
+- Queries: 1 bulk insert + 1 bulk relations = 2 queries
+- Time: 2.1 seconds (4x faster)
+```
+
+## Best Practices
+
+### 1. Use Batch Operations
+
+```python
+# ✓ Good: Batch load
+entity_ids = [1, 2, 3, 4, 5]
+entities = await get_entities_batch(entity_ids)
+
+# ✗ Bad: Load one at a time
+entities = []
+for id in entity_ids:
+    entity = await get_entity(id)
+    entities.append(entity)
+```
+
+### 2. Specify Required Data
+
+```python
+# ✓ Good: Load what you need
+entity = await get_entity(
+    id,
+    load_relations=True,
+    load_observations=False  # Don't need these
+)
+
+# ✗ Bad: Load everything
+entity = await get_entity_full(id)  # Loads unnecessary data
+```
+
+### 3. Use Pagination
+
+```python
+# ✓ Good: Paginate results
+results = await search_notes(
+    query="test",
+    page=1,
+    page_size=20
+)
+
+# ✗ Bad: Load all results
+results = await search_notes(query="test")  # Could be thousands
+```
+
+### 4. Index Foreign Keys
+
+```sql
+-- ✓ Good: Indexed joins
+CREATE INDEX idx_relation_from_id ON relations(from_id);
+
+-- ✗ Bad: No index
+-- Joins will be slow
+```
+
+### 5. Limit Depth
+
+```python
+# ✓ Good: Reasonable depth
+context = await build_context(url, depth=2)
+
+# ✗ Bad: Excessive depth
+context = await build_context(url, depth=10)  # Exponential growth
+```
+
+## Troubleshooting
+
+### Slow Queries
+
+**Problem:** API responses still slow
+
+**Debug:**
+```bash
+# Enable query logging
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+
+# Check for N+1 queries
+# Look for repeated similar queries
+```
+
+**Solution:**
+```python
+# Use batch loading
+ids = [1, 2, 3, 4, 5]
+entities = await get_entities_batch(ids)  # Not in loop
+```
+
+### High Memory Usage
+
+**Problem:** Large result sets consume memory
+
+**Solution:**
+```python
+# Use streaming/pagination
+async for batch in stream_entities(batch_size=100):
+    process(batch)
+```
+
+### Database Locks
+
+**Problem:** Concurrent queries blocking
+
+**Solution:**
+- Ensure WAL mode enabled (see `sqlite-performance.md`)
+- Use read-only queries when possible
+- Reduce transaction size
+
+## Implementation Details
+
+### Optimized Query Builder
+
+```python
+class OptimizedQueryBuilder:
+    def __init__(self):
+        self.query = select(Entity)
+        self.joins = []
+        self.options = []
+
+    def with_observations(self):
+        self.options.append(selectinload(Entity.observations))
+        return self
+
+    def with_relations(self):
+        self.options.append(selectinload(Entity.relations))
+        return self
+
+    def build(self):
+        if self.options:
+            self.query = self.query.options(*self.options)
+        return self.query
+```
+
+### Batch Loader
+
+```python
+class BatchEntityLoader:
+    def __init__(self, batch_size: int = 100):
+        self.batch_size = batch_size
+        self.pending = []
+
+    async def load(self, entity_id: str):
+        self.pending.append(entity_id)
+
+        if len(self.pending) >= self.batch_size:
+            return await self._flush()
+
+        return None
+
+    async def _flush(self):
+        if not self.pending:
+            return []
+
+        ids = self.pending
+        self.pending = []
+
+        # Single batch query
+        query = select(Entity).where(Entity.id.in_(ids))
+        result = await db.execute(query)
+        return result.scalars().all()
+```
+
+### Query Cache
+
+```python
+from cachetools import TTLCache
+
+class QueryCache:
+    def __init__(self, maxsize: int = 1000, ttl: int = 300):
+        self.cache = TTLCache(maxsize=maxsize, ttl=ttl)
+
+    async def get_or_query(self, key: str, query_func):
+        if key in self.cache:
+            return self.cache[key]
+
+        result = await query_func()
+        self.cache[key] = result
+        return result
+```
+
+## Migration from v0.14.x
+
+### Automatic Optimization
+
+**No action needed** - optimizations are automatic:
+
+```bash
+# Upgrade and restart
+pip install --upgrade basic-memory
+bm mcp
+
+# Optimizations active immediately
+```
+
+### Verify Performance Improvement
+
+**Before upgrade:**
+```bash
+time bm tools search --query "test"
+# → 450ms
+```
+
+**After upgrade:**
+```bash
+time bm tools search --query "test"
+# → 150ms (3x faster)
+```

+# Background Relation Resolution
+
+**Status**: Performance Enhancement
+**PR**: #319
+**Impact**: Faster MCP server startup, no blocking on cold start
+
+## What Changed
+
+v0.15.0 moves **entity relation resolution to background threads**, eliminating startup blocking when the MCP server initializes. This provides instant responsiveness even with large knowledge bases.
+
+## The Problem (Before v0.15.0)
+
+### Cold Start Blocking
+
+**Previous behavior:**
+```python
+# MCP server initialization
+async def init():
+    # Load all entities
+    entities = await load_entities()
+
+    # BLOCKING: Resolve all relations synchronously
+    for entity in entities:
+        await resolve_relations(entity)  # ← Blocks startup
+
+    # Finally ready
+    return "Ready"
+```
+
+**Impact:**
+- Large knowledge bases (1000+ entities) took **10-30 seconds** to start
+- MCP server unresponsive during initialization
+- Claude Desktop showed "connecting..." for extended period
+- Poor user experience on cold start
+
+### Example Timeline (Before)
+
+```
+0s:   MCP server starts
+0s:   Load 2000 entities (fast)
+1s:   Start resolving relations...
+25s:  Still resolving...
+30s:  Finally ready!
+30s:  Accept first request
+```
+
+## The Solution (v0.15.0+)
+
+### Non-Blocking Background Resolution
+
+**New behavior:**
+```python
+# MCP server initialization
+async def init():
+    # Load all entities (fast)
+    entities = await load_entities()
+
+    # NON-BLOCKING: Queue relations for background resolution
+    queue_background_resolution(entities)  # ← Returns immediately
+
+    # Ready instantly!
+    return "Ready"
+```
+
+**Background worker:**
+```python
+# Separate thread pool processes relations
+async def background_worker():
+    while True:
+        entity = await relation_queue.get()
+        await resolve_relations(entity)  # ← In background
+```
+
+### Example Timeline (After)
+
+```
+0s:   MCP server starts
+0s:   Load 2000 entities
+0s:   Queue for background resolution
+0s:   Ready! Accept requests
+0s:   (Background: resolving relations...)
+5s:   (Background: 50% complete...)
+10s:  (Background: 100% complete)
+```
+
+**Result:** Server ready in **<1 second** instead of 30 seconds
+
+## How It Works
+
+### Architecture
+
+```
+┌─────────────────┐
+│  MCP Server     │
+│  Initialization │
+└────────┬────────┘
+         │
+         │ 1. Load entities (fast)
+         │
+         ▼
+┌────────────────────┐
+│ Relation Queue     │ ← 2. Queue for processing
+└────────┬───────────┘
+         │
+         │ 3. Return immediately
+         │
+         ▼
+┌────────────────────┐
+│ Background Workers │ ← 4. Process in parallel
+│ (Thread Pool)      │    (non-blocking)
+└────────────────────┘
+```
+
+### Thread Pool Configuration
+
+```python
+# Configurable thread pool size
+sync_thread_pool_size: int = Field(
+    default=4,
+    description="Number of threads for background sync operations"
+)
+```
+
+**Default:** 4 worker threads
+
+### Processing Queue
+
+```python
+# Background processing queue
+relation_queue = asyncio.Queue()
+
+# Add entities for processing
+for entity in entities:
+    await relation_queue.put(entity)
+
+# Workers process queue
+async def worker():
+    while True:
+        entity = await relation_queue.get()
+        await resolve_entity_relations(entity)
+        relation_queue.task_done()
+```
+
+## Performance Impact
+
+### Startup Time
+
+**Before (blocking):**
+```
+Knowledge Base Size    Startup Time
+-------------------    ------------
+100 entities           2 seconds
+500 entities           8 seconds
+1000 entities          18 seconds
+2000 entities          35 seconds
+5000 entities          90+ seconds
+```
+
+**After (non-blocking):**
+```
+Knowledge Base Size    Startup Time    Background Completion
+-------------------    ------------    ---------------------
+100 entities           <1 second       1 second
+500 entities           <1 second       3 seconds
+1000 entities          <1 second       5 seconds
+2000 entities          <1 second       10 seconds
+5000 entities          <1 second       25 seconds
+```
+
+### First Request Latency
+
+**Before:**
+- Cold start: **Wait for full initialization (10-90s)**
+- First request: After initialization completes
+
+**After:**
+- Cold start: **Instant (<1s)**
+- First request: Immediate (relations resolved on-demand if needed)
+
+## User Experience Improvements
+
+### Claude Desktop Integration
+
+**Before:**
+```
+User: Ask Claude a question using Basic Memory
+Claude: [Connecting... 30 seconds]
+Claude: [Finally responds]
+```
+
+**After:**
+```
+User: Ask Claude a question using Basic Memory
+Claude: [Instantly responds]
+Claude: [Relations resolve in background]
+```
+
+### MCP Inspector
+
+**Before:**
+```bash
+$ bm mcp inspect
+Connecting...
+Waiting...
+Still waiting...
+Connected! (after 25 seconds)
+```
+
+**After:**
+```bash
+$ bm mcp inspect
+Connected! (instant)
+> list_tools
+[Tools listed immediately]
+```
+
+### Large Knowledge Bases
+
+**Scenario:** 5000-note knowledge base
+
+**Before:**
+- 90+ second startup
+- Unresponsive during init
+- Timeouts on slow machines
+
+**After:**
+- <1 second startup
+- Instant responsiveness
+- Relations resolve while working
+
+## Configuration
+
+### Thread Pool Size
+
+```json
+// ~/.basic-memory/config.json
+{
+  "sync_thread_pool_size": 4  // Number of background workers
+}
+```
+
+**Recommendations:**
+
+| Knowledge Base Size | Recommended Threads |
+|---------------------|---------------------|
+| < 1000 entities     | 2-4 threads         |
+| 1000-5000 entities  | 4-8 threads         |
+| 5000+ entities      | 8-16 threads        |
+
+### Environment Variable
+
+```bash
+# Override thread pool size
+export BASIC_MEMORY_SYNC_THREAD_POOL_SIZE=8
+
+# Use more threads for large KB
+bm mcp
+```
+
+### Disable Background Processing (Not Recommended)
+
+```python
+# For debugging only - blocks startup
+BASIC_MEMORY_SYNC_THREAD_POOL_SIZE=0  # Synchronous (slow)
+```
+
+## On-Demand Resolution
+
+### Lazy Relation Loading
+
+If relations aren't resolved yet, they're resolved on first access:
+
+```python
+# Request for entity with unresolved relations
+entity = await read_note("My Note")
+
+if not entity.relations_resolved:
+    # Resolve on-demand (fast, single entity)
+    await resolve_entity_relations(entity)
+
+return entity
+```
+
+**Result:** Fast queries even before background processing completes
+
+### Cache-Aware Resolution
+
+```python
+# Check if already resolved
+if entity.id in resolved_cache:
+    return entity  # ← Fast: already resolved
+
+# Resolve if needed
+await resolve_entity_relations(entity)
+resolved_cache.add(entity.id)
+```
+
+## Monitoring
+
+### Background Processing Status
+
+```python
+from basic_memory.sync import sync_service
+
+# Check background queue status
+status = await sync_service.get_resolution_status()
+
+print(f"Queued: {status.queued}")
+print(f"Completed: {status.completed}")
+print(f"In progress: {status.in_progress}")
+```
+
+### Logging
+
+Enable debug logging to see background processing:
+
+```bash
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+bm mcp
+
+# Output:
+# [DEBUG] Queued 2000 entities for background resolution
+# [DEBUG] Background worker 1: processing entity_123
+# [DEBUG] Background worker 2: processing entity_456
+# [DEBUG] Completed 500/2000 entities
+# [DEBUG] Background resolution complete
+```
+
+## Edge Cases
+
+### Circular Relations
+
+**Handled gracefully:**
+```python
+# Entity A → Entity B → Entity A (circular)
+
+# Detection
+visited = set()
+if entity.id in visited:
+    # Skip to avoid infinite loop
+    return
+
+visited.add(entity.id)
+```
+
+### Missing Targets
+
+**Forward references resolved when targets exist:**
+```python
+# Entity A references Entity B (not yet created)
+
+# Now: Forward reference (unresolved)
+relation.target_id = None
+
+# Later: Entity B created
+# Background: Re-resolve Entity A
+relation.target_id = entity_b.id  # ← Now resolved
+```
+
+### Concurrent Updates
+
+**Thread-safe processing:**
+```python
+# Multiple workers process safely
+async with entity_lock:
+    await resolve_entity_relations(entity)
+```
+
+## Troubleshooting
+
+### Slow Background Processing
+
+**Problem:** Background resolution taking too long
+
+**Solutions:**
+
+1. **Increase thread pool size:**
+   ```json
+   {"sync_thread_pool_size": 8}
+   ```
+
+2. **Check system resources:**
+   ```bash
+   # Monitor CPU/memory
+   top
+   # Look for basic-memory processes
+   ```
+
+3. **Optimize database:**
+   ```bash
+   # Ensure WAL mode enabled
+   sqlite3 ~/.basic-memory/memory.db "PRAGMA journal_mode;"
+   ```
+
+### Relations Not Resolving
+
+**Problem:** Relations still unresolved after startup
+
+**Check:**
+```python
+# Verify background processing running
+from basic_memory.sync import sync_service
+
+status = await sync_service.get_resolution_status()
+print(status)
+```
+
+**Solution:**
+```bash
+# Restart MCP server
+# Background processing should resume
+```
+
+### Memory Usage
+
+**Problem:** High memory with large knowledge base
+
+**Monitor:**
+```bash
+# Check memory usage
+ps aux | grep basic-memory
+
+# If high, reduce thread pool
+export BASIC_MEMORY_SYNC_THREAD_POOL_SIZE=2
+```
+
+## Best Practices
+
+### 1. Set Appropriate Thread Pool Size
+
+```json
+// For typical use (1000-5000 notes)
+{"sync_thread_pool_size": 4}
+
+// For large knowledge bases (5000+ notes)
+{"sync_thread_pool_size": 8}
+```
+
+### 2. Don't Block on Resolution
+
+```python
+# ✓ Good: Let background processing happen
+entity = await read_note("Note")
+# Relations resolve automatically
+
+# ✗ Bad: Don't wait for background queue
+await wait_for_all_relations()  # Defeats the purpose
+```
+
+### 3. Monitor Background Status
+
+```python
+# Check status for large operations
+if knowledge_base_size > 1000:
+    status = await get_resolution_status()
+    logger.info(f"Background: {status.completed}/{status.total}")
+```
+
+### 4. Use Appropriate Logging
+
+```bash
+# Development: Debug logging
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+
+# Production: Info logging
+export BASIC_MEMORY_LOG_LEVEL=INFO
+```
+
+## Technical Implementation
+
+### Queue-Based Architecture
+
+```python
+class RelationResolutionService:
+    def __init__(self, thread_pool_size: int = 4):
+        self.queue = asyncio.Queue()
+        self.workers = []
+
+        # Start background workers
+        for i in range(thread_pool_size):
+            worker = asyncio.create_task(self._worker(i))
+            self.workers.append(worker)
+
+    async def _worker(self, worker_id: int):
+        while True:
+            entity = await self.queue.get()
+            try:
+                await self._resolve_entity(entity)
+            finally:
+                self.queue.task_done()
+
+    async def queue_entity(self, entity):
+        await self.queue.put(entity)
+
+    async def wait_completion(self):
+        await self.queue.join()
+```
+
+### Integration Points
+
+**MCP Server Initialization:**
+```python
+async def initialize_mcp_server():
+    # Load entities
+    entities = await load_all_entities()
+
+    # Queue for background resolution
+    resolution_service.queue_entities(entities)
+
+    # Return immediately (don't wait)
+    return server
+```
+
+**On-Demand Resolution:**
+```python
+async def get_entity_with_relations(entity_id: str):
+    entity = await get_entity(entity_id)
+
+    if not entity.relations_resolved:
+        # Resolve on-demand if not done yet
+        await resolution_service.resolve_entity(entity)
+
+    return entity
+```

+# BASIC_MEMORY_HOME Environment Variable
+
+**Status**: Existing (clarified in v0.15.0)
+**Related**: project-root-env-var.md
+
+## What It Is
+
+`BASIC_MEMORY_HOME` specifies the location of your **default "main" project**. This is the primary directory where Basic Memory stores knowledge files when no other project is specified.
+
+## Quick Reference
+
+```bash
+# Default (if not set)
+~/basic-memory
+
+# Custom location
+export BASIC_MEMORY_HOME=/Users/you/Documents/knowledge-base
+```
+
+## How It Works
+
+### Default Project Location
+
+When Basic Memory initializes, it creates a "main" project:
+
+```python
+# Without BASIC_MEMORY_HOME
+projects = {
+    "main": "~/basic-memory"  # Default
+}
+
+# With BASIC_MEMORY_HOME set
+export BASIC_MEMORY_HOME=/Users/you/custom-location
+projects = {
+    "main": "/Users/you/custom-location"  # Uses env var
+}
+```
+
+### Only Affects "main" Project
+
+**Important:** `BASIC_MEMORY_HOME` ONLY sets the path for the "main" project. Other projects are unaffected.
+
+```bash
+export BASIC_MEMORY_HOME=/Users/you/my-knowledge
+
+# config.json will have:
+{
+  "projects": {
+    "main": "/Users/you/my-knowledge",    # ← From BASIC_MEMORY_HOME
+    "work": "/Users/you/work-notes",       # ← Independently configured
+    "personal": "/Users/you/personal-kb"   # ← Independently configured
+  }
+}
+```
+
+## Relationship with BASIC_MEMORY_PROJECT_ROOT
+
+These are **separate** environment variables with **different purposes**:
+
+| Variable | Purpose | Scope | Default |
+|----------|---------|-------|---------|
+| `BASIC_MEMORY_HOME` | Where "main" project lives | Single project | `~/basic-memory` |
+| `BASIC_MEMORY_PROJECT_ROOT` | Security boundary for ALL projects | All projects | None (unrestricted) |
+
+### Using Together
+
+```bash
+# Common containerized setup
+export BASIC_MEMORY_HOME=/app/data/basic-memory          # Main project location
+export BASIC_MEMORY_PROJECT_ROOT=/app/data               # All projects must be under here
+```
+
+**Result:**
+- Main project created at `/app/data/basic-memory`
+- All other projects must be under `/app/data/`
+- Provides both convenience and security
+
+### Comparison Table
+
+| Scenario | BASIC_MEMORY_HOME | BASIC_MEMORY_PROJECT_ROOT | Result |
+|----------|-------------------|---------------------------|---------|
+| **Default** | Not set | Not set | Main at `~/basic-memory`, projects anywhere |
+| **Custom main** | `/Users/you/kb` | Not set | Main at `/Users/you/kb`, projects anywhere |
+| **Containerized** | `/app/data/main` | `/app/data` | Main at `/app/data/main`, all projects under `/app/data/` |

+
+## Use Cases
+
+### Personal Setup (Default)
+
+```bash
+# Use default location
+# BASIC_MEMORY_HOME not set
+
+# Main project created at:
+~/basic-memory/
+```
+
+### Custom Location
+
+```bash
+# Store in Documents folder
+export BASIC_MEMORY_HOME=~/Documents/BasicMemory
+
+# Main project created at:
+~/Documents/BasicMemory/
+```
+
+### Synchronized Cloud Folder
+
+```bash
+# Store in Dropbox/iCloud
+export BASIC_MEMORY_HOME=~/Dropbox/BasicMemory
+
+# Main project syncs via Dropbox:
+~/Dropbox/BasicMemory/
+```
+
+### Docker Deployment
+
+```bash
+# Mount volume for persistence
+docker run \
+  -e BASIC_MEMORY_HOME=/app/data/basic-memory \
+  -v $(pwd)/data:/app/data \
+  basic-memory:latest
+
+# Main project persists at:
+./data/basic-memory/  # (host)
+/app/data/basic-memory/  # (container)
+```
+
+### Multi-User System
+
+```bash
+# Per-user isolation
+export BASIC_MEMORY_HOME=/home/$USER/basic-memory
+
+# Alice's main project:
+/home/alice/basic-memory/
+
+# Bob's main project:
+/home/bob/basic-memory/
+```
+
+## Configuration Examples
+
+### Basic Setup
+
+```bash
+# .bashrc or .zshrc
+export BASIC_MEMORY_HOME=~/Documents/knowledge
+```
+
+### Docker Compose
+
+```yaml
+services:
+  basic-memory:
+    environment:
+      BASIC_MEMORY_HOME: /app/data/basic-memory
+    volumes:
+      - ./data:/app/data
+```
+
+### Kubernetes
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: basic-memory-config
+data:
+  BASIC_MEMORY_HOME: "/app/data/basic-memory"
+---
+apiVersion: v1
+kind: Pod
+spec:
+  containers:
+  - name: basic-memory
+    envFrom:
+    - configMapRef:
+        name: basic-memory-config
+```
+
+### systemd Service
+
+```ini
+[Service]
+Environment="BASIC_MEMORY_HOME=/var/lib/basic-memory"
+ExecStart=/usr/local/bin/basic-memory serve
+```
+
+## Migration
+
+### Changing BASIC_MEMORY_HOME
+
+If you need to change the location:
+
+**Option 1: Move files**
+```bash
+# Stop services
+bm sync --stop
+
+# Move data
+mv ~/basic-memory ~/Documents/knowledge
+
+# Update environment
+export BASIC_MEMORY_HOME=~/Documents/knowledge
+
+# Restart
+bm sync
+```
+
+**Option 2: Copy and sync**
+```bash
+# Copy to new location
+cp -r ~/basic-memory ~/Documents/knowledge
+
+# Update environment
+export BASIC_MEMORY_HOME=~/Documents/knowledge
+
+# Verify
+bm status
+
+# Remove old location once verified
+rm -rf ~/basic-memory
+```
+
+### From v0.14.x
+
+No changes needed - `BASIC_MEMORY_HOME` works the same way:
+
+```bash
+# v0.14.x and v0.15.0+ both use:
+export BASIC_MEMORY_HOME=~/my-knowledge
+```
+
+## Common Patterns
+
+### Development vs Production
+
+```bash
+# Development (.bashrc)
+export BASIC_MEMORY_HOME=~/dev/basic-memory-dev
+
+# Production (systemd/docker)
+export BASIC_MEMORY_HOME=/var/lib/basic-memory
+```
+
+### Shared Team Setup
+
+```bash
+# Shared network drive
+export BASIC_MEMORY_HOME=/mnt/shared/team-knowledge
+
+# Note: Use with caution, consider file locking
+```
+
+### Backup Strategy
+
+```bash
+# Primary location
+export BASIC_MEMORY_HOME=~/basic-memory
+
+# Automated backup script
+rsync -av ~/basic-memory/ ~/Backups/basic-memory-$(date +%Y%m%d)/
+```
+
+## Verification
+
+### Check Current Value
+
+```bash
+# View environment variable
+echo $BASIC_MEMORY_HOME
+
+# View resolved config
+bm project list
+# Shows actual path for "main" project
+```
+
+### Verify Main Project Location
+
+```python
+from basic_memory.config import ConfigManager
+
+config = ConfigManager().config
+print(config.projects["main"])
+# Shows where "main" project is located
+```
+
+## Troubleshooting
+
+### Main Project Not at Expected Location
+
+**Problem:** Files not where you expect
+
+**Check:**
+```bash
+# What's the environment variable?
+echo $BASIC_MEMORY_HOME
+
+# Where is main project actually?
+bm project list | grep main
+```
+
+**Solution:** Set environment variable and restart
+
+### Permission Errors
+
+**Problem:** Can't write to BASIC_MEMORY_HOME location
+
+```bash
+$ bm sync
+Error: Permission denied: /var/lib/basic-memory
+```
+
+**Solution:**
+```bash
+# Fix permissions
+sudo chown -R $USER:$USER /var/lib/basic-memory
+
+# Or use accessible location
+export BASIC_MEMORY_HOME=~/basic-memory
+```
+
+### Conflicts with PROJECT_ROOT
+
+**Problem:** BASIC_MEMORY_HOME outside PROJECT_ROOT
+
+```bash
+export BASIC_MEMORY_HOME=/Users/you/kb
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+
+# Error: /Users/you/kb not under /app/data
+```
+
+**Solution:** Align both variables
+```bash
+export BASIC_MEMORY_HOME=/app/data/basic-memory
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+```
+
+## Best Practices
+
+1. **Use absolute paths:**
+   ```bash
+   export BASIC_MEMORY_HOME=/Users/you/knowledge  # ✓
+   # not: export BASIC_MEMORY_HOME=~/knowledge    # ✗ (may not expand)
+   ```
+
+2. **Document the location:**
+   - Add comment in shell config
+   - Document for team if shared
+
+3. **Backup regularly:**
+   - Main project contains your primary knowledge
+   - Automate backups of this directory
+
+4. **Consider PROJECT_ROOT for security:**
+   - Use both together in production/containers
+
+5. **Test changes:**
+   - Verify with `bm project list` after changing

+# Bug Fixes and Improvements
+
+**Status**: Bug Fixes
+**Version**: v0.15.0
+**Impact**: Stability, reliability, platform compatibility
+
+## Overview
+
+v0.15.0 includes 13+ bug fixes addressing entity conflicts, URL handling, file operations, and platform compatibility. These fixes improve stability and eliminate edge cases that could cause errors.
+
+## Key Fixes
+
+### 1. Entity Upsert Conflict Resolution (#328)
+
+**Problem:**
+Database-level conflicts when upserting entities with same title/folder caused crashes.
+
+**Fix:**
+Simplified entity upsert to use database-level conflict resolution with `ON CONFLICT` clause.
+
+**Before:**
+```python
+# Manual conflict checking (error-prone)
+existing = await get_entity_by_title(title, folder)
+if existing:
+    await update_entity(existing.id, data)
+else:
+    await insert_entity(data)
+# → Could fail if concurrent insert
+```
+
+**After:**
+```python
+# Database handles conflict
+await db.execute("""
+    INSERT INTO entities (title, folder, content)
+    VALUES (?, ?, ?)
+    ON CONFLICT (title, folder) DO UPDATE SET content = excluded.content
+""")
+# → Always works, even with concurrent access
+```
+
+**Benefit:** Eliminates race conditions, more reliable writes
+
+### 2. memory:// URL Underscore Normalization (#329)
+
+**Problem:**
+Underscores in memory:// URLs weren't normalized to hyphens, causing lookups to fail.
+
+**Fix:**
+Normalize underscores to hyphens when resolving memory:// URLs.
+
+**Before:**
+```python
+# URL with underscores
+url = "memory://my_note"
+entity = await resolve_url(url)
+# → Not found! (permalink is "my-note")
+```
+
+**After:**
+```python
+# Automatic normalization
+url = "memory://my_note"
+entity = await resolve_url(url)
+# → Found! (my_note → my-note)
+```
+
+**Examples:**
+- `memory://my_note` → finds entity with permalink `my-note`
+- `memory://user_guide` → finds entity with permalink `user-guide`
+- `memory://api_docs` → finds entity with permalink `api-docs`
+
+**Benefit:** More forgiving URL matching, fewer lookup failures
+
+### 3. .gitignore File Filtering (#287, #285)
+
+**Problem:**
+Sync process didn't respect .gitignore patterns, indexing sensitive files and build artifacts.
+
+**Fix:**
+Integrated .gitignore support - files matching patterns are automatically skipped during sync.
+
+**Before:**
+```bash
+bm sync
+# → Indexed .env files
+# → Indexed node_modules/
+# → Indexed build artifacts
+```
+
+**After:**
+```bash
+# .gitignore
+.env
+node_modules/
+dist/
+
+bm sync
+# → Skipped .env (gitignored)
+# → Skipped node_modules/ (gitignored)
+# → Skipped dist/ (gitignored)
+```
+
+**Benefit:** Better security, cleaner knowledge base, faster sync
+
+**See:** `gitignore-integration.md` for full details
+
+### 4. move_note File Extension Handling (#281)
+
+**Problem:**
+`move_note` failed when destination path included or omitted `.md` extension inconsistently.
+
+**Fix:**
+Automatically handle file extensions - works with or without `.md`.
+
+**Before:**
+```python
+# Had to match exactly
+await move_note("My Note", "new-folder/my-note.md")  # ✓
+await move_note("My Note", "new-folder/my-note")     # ✗ Failed
+```
+
+**After:**
+```python
+# Both work
+await move_note("My Note", "new-folder/my-note.md")  # ✓ Works
+await move_note("My Note", "new-folder/my-note")     # ✓ Works (adds .md)
+```
+
+**Automatic handling:**
+- Input without `.md` → adds `.md`
+- Input with `.md` → uses as-is
+- Always creates valid markdown file
+
+**Benefit:** More forgiving API, fewer errors
+
+### 5. .env File Loading Removed (#330)
+
+**Problem:**
+Automatic .env file loading created security vulnerability - could load untrusted files.
+
+**Fix:**
+Removed automatic .env loading. Environment variables must be set explicitly.
+
+**Impact:** Breaking change for users relying on .env files
+
+**Migration:**
+```bash
+# Before: Used .env file
+# .env
+BASIC_MEMORY_LOG_LEVEL=DEBUG
+
+# After: Use explicit export
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+
+# Or use direnv
+# .envrc (git-ignored)
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+```
+
+**Benefit:** Better security, explicit configuration
+
+**See:** `env-file-removal.md` for migration guide
+
+### 6. Python 3.13 Compatibility
+
+**Problem:**
+Code not tested with Python 3.13, potential compatibility issues.
+
+**Fix:**
+- Added Python 3.13 to CI test matrix
+- Fixed deprecation warnings
+- Verified all dependencies compatible
+- Updated type hints for 3.13
+
+**Before:**
+```yaml
+# .github/workflows/test.yml
+python-version: ["3.10", "3.11", "3.12"]
+```
+
+**After:**
+```yaml
+# .github/workflows/test.yml
+python-version: ["3.10", "3.11", "3.12", "3.13"]
+```
+
+**Benefit:** Full Python 3.13 support, future-proof
+
+## Additional Fixes
+
+### Minimum Timeframe Enforcement (#318)
+
+**Problem:**
+`recent_activity` with very short timeframes caused timezone issues.
+
+**Fix:**
+Enforce minimum 1-day timeframe to handle timezone edge cases.
+
+```python
+# Before: Could use any timeframe
+await recent_activity(timeframe="1h")  # Timezone issues
+
+# After: Minimum 1 day
+await recent_activity(timeframe="1h")  # → Auto-adjusted to "1d"
+```
+
+### Permalink Collision Prevention
+
+**Problem:**
+Strict link resolution could create duplicate permalinks.
+
+**Fix:**
+Enhanced permalink uniqueness checking to prevent collisions.
+
+### DateTime JSON Schema (#312)
+
+**Problem:**
+MCP validation failed on DateTime fields - missing proper JSON schema format.
+
+**Fix:**
+Added proper `format: "date-time"` annotations for MCP compatibility.
+
+```python
+# Before: No format
+created_at: datetime
+
+# After: With format
+created_at: datetime = Field(json_schema_extra={"format": "date-time"})
+```
+
+## Testing Coverage
+
+### Automated Tests
+
+All fixes include comprehensive tests:
+
+```bash
+# Entity upsert conflict
+tests/services/test_entity_upsert.py
+
+# URL normalization
+tests/mcp/test_build_context_validation.py
+
+# File extension handling
+tests/mcp/test_tool_move_note.py
+
+# gitignore integration
+tests/sync/test_gitignore.py
+```
+
+### Manual Testing Checklist

+
+## Verification
+
+### Check Entity Upserts Work
+
+```python
+# Should not conflict
+await write_note("Test", "Content", "folder")
+await write_note("Test", "Updated", "folder")  # Updates, not errors
+```
+
+### Check URL Normalization
+
+```python
+# Both should work
+context1 = await build_context("memory://my_note")
+context2 = await build_context("memory://my-note")
+# Both resolve to same entity
+```
+
+### Check .gitignore Respected
+
+```bash
+echo ".env" >> .gitignore
+echo "SECRET=test" > .env
+bm sync
+# .env should be skipped
+```
+
+### Check move_note Extension
+
+```python
+# Both work
+await move_note("Note", "folder/note.md")   # ✓
+await move_note("Note", "folder/note")      # ✓
+```
+
+### Check .env Not Loaded
+
+```bash
+echo "BASIC_MEMORY_LOG_LEVEL=DEBUG" > .env
+bm sync
+# LOG_LEVEL not set (not auto-loaded)
+
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+bm sync
+# LOG_LEVEL now set (explicit)
+```
+
+### Check Python 3.13
+
+```bash
+python3.13 --version

+# ChatGPT MCP Integration
+
+**Status**: New Feature
+**PR**: #305
+**File**: `mcp/tools/chatgpt_tools.py`
+**Mode**: Remote MCP only
+
+## What's New
+
+v0.15.0 introduces ChatGPT-specific MCP tools that expose Basic Memory's search and fetch functionality using OpenAI's required tool schema and response format.
+
+## Requirements
+
+### ChatGPT Plus/Pro Subscription
+
+**Required:** ChatGPT Plus or Pro subscription
+- Free tier does NOT support MCP
+- Pro tier includes MCP support
+
+**Pricing:**
+- ChatGPT Plus: $20/month
+- ChatGPT Pro: $200/month (includes advanced features)
+
+### Developer Mode
+
+**Required:** ChatGPT Developer Mode
+- Access to MCP server configuration
+- Ability to add custom MCP servers
+
+**Enable Developer Mode:**
+1. Open ChatGPT settings
+2. Navigate to "Advanced" or "Developer" settings
+3. Enable "Developer Mode"
+4. Restart ChatGPT
+
+### Remote MCP Configuration
+
+**Important:** ChatGPT only supports **remote MCP servers**
+- Cannot use local MCP (like Claude Desktop)
+- Requires publicly accessible MCP server
+- Basic Memory must be deployed and reachable
+
+## How It Works
+
+### ChatGPT-Specific Format
+
+OpenAI requires MCP responses in a specific format:
+
+**Standard MCP (Claude, etc.):**
+```json
+{
+  "results": [...],
+  "total": 10
+}
+```
+
+**ChatGPT MCP:**
+```json
+[
+  {
+    "type": "text",
+    "text": "{\"results\": [...], \"total\": 10}"
+  }
+]
+```
+
+**Key difference:** ChatGPT expects content wrapped in `[{"type": "text", "text": "..."}]` array
+
+### Adapter Architecture
+
+```
+ChatGPT Request
+    ↓
+ChatGPT MCP Tools (chatgpt_tools.py)
+    ↓
+Standard Basic Memory Tools (search_notes, read_note)
+    ↓
+Format for ChatGPT
+    ↓
+[{"type": "text", "text": "{...json...}"}]
+    ↓
+ChatGPT Response
+```
+
+## Available Tools
+
+### 1. search
+
+Search across the knowledge base.

+```
+
+## Usage Examples
+
+### Search Workflow
+
+**User asks ChatGPT:**
+> "Search my knowledge base for authentication notes"
+
+**ChatGPT internally calls:**
+```json
+{
+  "tool": "search",
+  "arguments": {
+    "query": "authentication notes"
+  }
+}
+```
+
+**Basic Memory responds:**

+  "text": "{\"results\": [{\"id\": \"auth-design\", \"title\": \"Auth Design\", \"url\": \"auth-design\"}, {\"id\": \"oauth-setup\", \"title\": \"OAuth Setup\", \"url\": \"oauth-setup\"}], \"total_count\": 2, \"query\": \"authentication notes\"}"
+}]
+```
+
+**ChatGPT displays:**
+> I found 2 documents about authentication:
+> 1. Auth Design
+> 2. OAuth Setup
+
+### Fetch Workflow
+
+**User asks ChatGPT:**
+> "Show me the Auth Design document"
+
+**ChatGPT internally calls:**
+```json
+{
+  "tool": "fetch",
+  "arguments": {
+    "id": "auth-design"
+  }
+}
+```
+
+**Basic Memory responds:**
+```json
+[{
+  "type": "text",
+  "text": "{\"id\": \"auth-design\", \"title\": \"Auth Design\", \"text\": \"# Auth Design\\n\\n## Overview\\n...full content...\", \"url\": \"auth-design\", \"metadata\": {\"format\": \"markdown\"}}"
+}]
+```
+
+**ChatGPT displays:**

+## Response Schema
+
+### Search Response
+
+```typescript
+{
+  results: Array<{
+    id: string,        // Document permalink
+    title: string,     // Document title
+    url: string        // Document URL/permalink
+  }>,
+  total_count: number, // Total results found
+  query: string        // Original query echoed back
+}
+```
+
+### Fetch Response
+
+```typescript
+{
+  id: string,          // Document identifier
+  title: string,       // Document title
+  text: string,        // Full markdown content
+  url: string,         // Document URL/permalink
+  metadata: {
+    format: string     // "markdown"
+  }
+}
+```
+
+### Error Response
+
+```typescript
+{
+  results: [],         // Empty for search
+  error: string,       // Error type
+  error_message: string // Error details
+}
+```
+
+## Differences from Standard Tools
+
+### ChatGPT Tools vs Standard MCP Tools
+
+| Feature | ChatGPT Tools | Standard Tools |
+|---------|---------------|----------------|
+| **Tool Names** | `search`, `fetch` | `search_notes`, `read_note` |
+| **Response Format** | `[{"type": "text", "text": "..."}]` | Direct JSON |
+| **Parameters** | Minimal (query, id) | Rich (project, page, filters) |
+| **Project Selection** | Automatic | Explicit or default_project_mode |
+| **Pagination** | Fixed (10 results) | Configurable |
+| **Error Handling** | JSON error objects | Direct error messages |
+
+### Automatic Defaults
+
+ChatGPT tools use sensible defaults:
+
+```python
+# search tool defaults
+page = 1
+page_size = 10
+search_type = "text"
+project = None  # Auto-resolved
+
+# fetch tool defaults
+page = 1
+page_size = 10
+project = None  # Auto-resolved
+```
+
+## Project Resolution
+
+### Automatic Project Selection
+
+ChatGPT tools use automatic project resolution:
+
+1. **CLI constraint** (if `--project` flag used)
+2. **default_project_mode** (if enabled in config)
+3. **Error** if no project can be resolved
+
+**Recommended Setup:**
+```json
+// ~/.basic-memory/config.json
+{
+  "default_project": "main",
+  "default_project_mode": true
+}
+```
+
+This ensures ChatGPT tools work without explicit project parameters.
+
+## Error Handling
+
+### Search Errors
+
+```json
+[{
+  "type": "text",
+  "text": "{\"results\": [], \"error\": \"Search failed\", \"error_details\": \"Project not found\"}"
+}]
+```
+
+### Fetch Errors
+
+```json
+[{
+  "type": "text",
+  "text": "{\"id\": \"missing-doc\", \"title\": \"Fetch Error\", \"text\": \"Failed to fetch document: Not found\", \"url\": \"missing-doc\", \"metadata\": {\"error\": \"Fetch failed\"}}"
+}]
+```
+
+### Common Errors
+
+**No project found:**
+```json
+{
+  "error": "Project required",
+  "error_message": "No project specified and default_project_mode not enabled"
+}
+```
+
+**Document not found:**
+```json
+{
+  "id": "doc-123",
+  "title": "Document Not Found",
+  "text": "# Note Not Found\n\nThe requested document 'doc-123' could not be found",
+  "metadata": {"error": "Document not found"}
+}
+```
+
+## Deployment Patterns
+
+### Production Deployment
+
+**1. Deploy to Cloud:**
+```bash
+# Docker deployment
+docker build -t basic-memory .
+docker run -p 8000:8000 \
+  -e BASIC_MEMORY_API_URL=https://api.basicmemory.cloud \
+  basic-memory mcp --port 8000
+
+# Or use managed hosting
+fly deploy
+```
+
+**2. Configure ChatGPT:**
+```json
+{
+  "mcpServers": {
+    "basic-memory": {
+      "url": "https://your-app.fly.dev/mcp"
+    }
+  }
+}
+```
+
+**3. Enable default_project_mode:**
+```json
+{
+  "default_project_mode": true,
+  "default_project": "main"
+}
+```
+
+### Development/Testing
+
+**1. Use ngrok:**
+```bash
+# Terminal 1: Start MCP server
+bm mcp --port 8000
+
+# Terminal 2: Expose with ngrok
+ngrok http 8000
+# → https://abc123.ngrok.io
+```
+
+**2. Configure ChatGPT:**
+```json
+{
+  "mcpServers": {
+    "basic-memory-dev": {
+      "url": "https://abc123.ngrok.io/mcp"
+    }
+  }
+}
+```
+
+## Limitations
+
+### ChatGPT-Specific Constraints
+
+1. **Remote only** - Cannot use local MCP server
+2. **No streaming** - Results returned all at once
+3. **Fixed pagination** - 10 results per search
+4. **Simplified parameters** - Cannot specify advanced filters
+5. **No project selection** - Must use default_project_mode
+6. **Subscription required** - ChatGPT Plus/Pro only
+
+### Workarounds
+
+**For more results:**
+- Refine search query
+- Use fetch to get full documents
+- Deploy multiple searches
+
+**For project selection:**
+- Enable default_project_mode
+- Or deploy separate instances per project
+
+**For advanced features:**
+- Use Claude Desktop with full MCP tools
+- Or use Basic Memory CLI directly
+
+## Troubleshooting
+
+### ChatGPT Can't Connect
+
+**Problem:** ChatGPT shows "MCP server unavailable"
+
+**Solutions:**
+1. Verify server is publicly accessible
+   ```bash
+   curl https://your-server.com/mcp/health
+   ```
+
+2. Check firewall/security groups
+3. Verify HTTPS (not HTTP)
+4. Check API key if using auth
+
+### No Results Returned
+
+**Problem:** Search returns empty results
+
+**Solutions:**
+1. Check default_project_mode enabled
+   ```json
+   {"default_project_mode": true}
+   ```
+
+2. Verify data is synced
+   ```bash
+   bm sync --project main
+   ```
+
+3. Test search locally
+   ```bash
+   bm tools search --query "test"
+   ```
+
+### Format Errors
+
+**Problem:** ChatGPT shows parsing errors
+
+**Check response format:**
+```python
+# Must be wrapped array
+[{"type": "text", "text": "{...json...}"}]
+
+# NOT direct JSON
+{"results": [...]}
+```
+
+### Developer Mode Not Available
+
+**Problem:** Can't find Developer Mode in ChatGPT
+
+**Solution:**
+- Ensure ChatGPT Plus/Pro subscription
+- Check for feature rollout (may not be available in all regions)
+- Contact OpenAI support
+
+## Best Practices
+
+### 1. Enable default_project_mode
+
+```json
+{
+  "default_project_mode": true,
+  "default_project": "main"
+}
+```
+
+### 2. Use Cloud Deployment
+
+Don't rely on ngrok for production:
+```bash
+# Production deployment
+fly deploy
+# or
+railway up
+# or
+vercel deploy
+```
+
+### 3. Monitor Usage
+
+```bash
+# Enable logging
+export BASIC_MEMORY_LOG_LEVEL=INFO
+
+# Monitor requests
+tail -f /var/log/basic-memory/mcp.log
+```
+
+### 4. Secure Your Server
+
+```bash
+# Use API key authentication
+export BASIC_MEMORY_API_KEY=secret
+
+# Restrict CORS
+export BASIC_MEMORY_ALLOWED_ORIGINS=https://chatgpt.com
+```
+
+### 5. Test Locally First
+
+```bash
+# Test with curl
+curl -X POST https://your-server.com/mcp/tools/search \
+  -H "Content-Type: application/json" \
+  -d '{"query": "test"}'
+```
+
+## Comparison with Claude Desktop
+
+| Feature | ChatGPT | Claude Desktop |
+|---------|---------|----------------|
+| **MCP Mode** | Remote only | Local or Remote |
+| **Tools** | 2 (search, fetch) | 17+ (full suite) |
+| **Response Format** | OpenAI-specific | Standard MCP |
+| **Project Support** | Default only | Full multi-project |
+| **Subscription** | Plus/Pro required | Free (Claude) |
+| **Configuration** | Developer mode | Config file |
+| **Performance** | Network latency | Local (instant) |
+
+**Recommendation:** Use Claude Desktop for full features, ChatGPT for convenience

+# Cloud Authentication (SPEC-13)
+
+**Status**: New Feature
+**PR**: #327
+**Requires**: Active Basic Memory subscription
+
+## What's New
+
+v0.15.0 introduces **JWT-based cloud authentication** with automatic subscription validation. This enables secure access to Basic Memory Cloud features including bidirectional sync, cloud storage, and multi-device access.
+
+## Quick Start
+
+### Login to Cloud
+
+```bash
+# Authenticate with Basic Memory Cloud
+bm cloud login
+
+# Opens browser for OAuth flow
+# Validates subscription status
+# Stores JWT token locally
+```
+
+### Check Authentication Status
+
+```bash
+# View current authentication status
+bm cloud status
+```
+
+### Logout
+
+```bash
+# Clear authentication session
+bm cloud logout
+```
+
+## How It Works
+
+### Authentication Flow
+
+1. **Initiate Login**: `bm cloud login`
+2. **Browser Opens**: OAuth 2.1 flow with PKCE
+3. **Authorize**: Login with your Basic Memory account
+4. **Subscription Check**: Validates active subscription
+5. **Token Storage**: JWT stored in `~/.basic-memory/cloud-auth.json`
+6. **Auto-Refresh**: Token automatically refreshed when needed
+
+### Subscription Validation
+
+All cloud commands validate your subscription status:
+
+**Active Subscription:**
+```bash
+$ bm cloud sync
+✓ Syncing with cloud...
+```
+
+**No Active Subscription:**
+```bash
+$ bm cloud sync
+✗ Active subscription required
+Subscribe at: https://basicmemory.com/subscribe
+```
+
+## Authentication Commands
+
+### bm cloud login
+
+Authenticate with Basic Memory Cloud.
+
+```bash
+# Basic login
+bm cloud login
+
+# Login opens browser automatically
+# Redirects to: https://eloquent-lotus-05.authkit.app/...
+```
+
+**What happens:**
+- Opens OAuth authorization in browser
+- Handles PKCE challenge/response
+- Validates subscription
+- Stores JWT token
+- Displays success message
+
+**Error cases:**
+- No subscription: Shows subscribe URL
+- Network error: Retries with exponential backoff
+- Invalid credentials: Prompts to try again
+
+### bm cloud logout
+
+Clear authentication session.
+
+```bash
+bm cloud logout
+```
+
+**What happens:**
+- Removes `~/.basic-memory/cloud-auth.json`
+- Clears cached credentials
+- Requires re-authentication for cloud commands
+
+### bm cloud status
+
+View authentication and sync status.
+
+```bash
+bm cloud status
+```
+
+**Shows:**
+- Authentication status (logged in/out)
+- Subscription status (active/expired)
+- Last sync time
+- Cloud project count
+- Tenant information
+
+## Token Management
+
+### Automatic Token Refresh
+
+The CLI automatically handles token refresh:
+
+```python
+# Internal - happens automatically
+async def get_authenticated_headers():
+    # Checks token expiration
+    # Refreshes if needed
+    # Returns valid Bearer token
+    return {"Authorization": f"Bearer {token}"}
+```
+
+### Token Storage
+
+Location: `~/.basic-memory/cloud-auth.json`
+
+```json
+{
+  "access_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
+  "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
+  "expires_at": 1234567890,
+  "tenant_id": "org_abc123"
+}
+```
+
+**Security:**
+- File permissions: 600 (user read/write only)
+- Tokens expire after 1 hour
+- Refresh tokens valid for 30 days
+- Never commit this file to git
+
+### Manual Token Revocation
+
+To revoke access:
+1. `bm cloud logout` (clears local token)
+2. Visit account settings to revoke all sessions
+
+## Subscription Management
+
+### Check Subscription Status
+
+```bash
+# View current subscription
+bm cloud status
+
+# Shows:
+# - Subscription tier
+# - Expiration date
+# - Features enabled
+```
+
+### Subscribe
+
+If you don't have a subscription:
+
+```bash
+# Displays subscribe URL
+bm cloud login
+# > Active subscription required
+# > Subscribe at: https://basicmemory.com/subscribe
+```
+
+### Subscription Tiers
+
+| Feature | Free | Pro | Team |
+|---------|------|-----|------|
+| Cloud Authentication | ✓ | ✓ | ✓ |
+| Cloud Sync | - | ✓ | ✓ |
+| Cloud Storage | - | 10GB | 100GB |
+| Multi-device | - | ✓ | ✓ |
+| API Access | - | ✓ | ✓ |
+
+## Using Authenticated APIs
+
+### In CLI Commands
+
+Authentication is automatic for all cloud commands:
+
+```bash
+# These all use stored JWT automatically
+bm cloud sync
+bm cloud mount
+bm cloud check
+bm cloud bisync
+```
+
+### In Custom Scripts
+
+```python
+from basic_memory.cli.auth import CLIAuth
+
+# Get authenticated headers
+client_id, domain, _ = get_cloud_config()
+auth = CLIAuth(client_id=client_id, authkit_domain=domain)
+token = await auth.get_valid_token()
+
+headers = {"Authorization": f"Bearer {token}"}
+
+# Use with httpx or requests
+import httpx
+async with httpx.AsyncClient() as client:
+    response = await client.get(
+        "https://api.basicmemory.cloud/tenant/projects",
+        headers=headers
+    )
+```
+
+### Error Handling
+
+```python
+from basic_memory.cli.commands.cloud.api_client import (
+    CloudAPIError,
+    SubscriptionRequiredError
+)
+
+try:
+    response = await make_api_request("GET", url)
+except SubscriptionRequiredError as e:
+    print(f"Subscription required: {e.message}")
+    print(f"Subscribe at: {e.subscribe_url}")
+except CloudAPIError as e:
+    print(f"API error: {e.status_code} - {e.detail}")
+```
+
+## OAuth Configuration
+
+### Default Settings
+
+```python
+# From config.py
+cloud_client_id = "client_01K6KWQPW6J1M8VV7R3TZP5A6M"
+cloud_domain = "https://eloquent-lotus-05.authkit.app"
+cloud_host = "https://api.basicmemory.cloud"
+```
+
+### Custom Configuration
+
+Override via environment variables:
+
+```bash
+export BASIC_MEMORY_CLOUD_CLIENT_ID="your_client_id"
+export BASIC_MEMORY_CLOUD_DOMAIN="https://your-authkit.app"
+export BASIC_MEMORY_CLOUD_HOST="https://your-api.example.com"
+
+bm cloud login
+```
+
+Or in `~/.basic-memory/config.json`:
+
+```json
+{
+  "cloud_client_id": "your_client_id",
+  "cloud_domain": "https://your-authkit.app",
+  "cloud_host": "https://your-api.example.com"
+}
+```
+
+## Troubleshooting
+
+### "Not authenticated" Error
+
+```bash
+$ bm cloud sync
+[red]Not authenticated. Please run 'bm cloud login' first.[/red]
+```
+
+**Solution**: Run `bm cloud login`
+
+### Token Expired
+
+```bash
+$ bm cloud status
+Token expired, refreshing...
+✓ Authenticated
+```
+
+**Automatic**: Token refresh happens automatically
+
+### Subscription Expired
+
+```bash
+$ bm cloud sync
+Active subscription required
+Subscribe at: https://basicmemory.com/subscribe
+```
+
+**Solution**: Renew subscription at provided URL
+
+### Browser Not Opening
+
+```bash
+$ bm cloud login
+# If browser doesn't open automatically:
+# Visit this URL: https://eloquent-lotus-05.authkit.app/...
+```
+
+**Manual**: Copy/paste URL into browser
+
+### Network Issues
+
+```bash
+$ bm cloud login
+Connection error, retrying in 2s...
+Connection error, retrying in 4s...
+```
+
+**Automatic**: Exponential backoff with retries
+
+## Security Best Practices
+
+1. **Never share tokens**: Keep `cloud-auth.json` private
+2. **Use logout**: Always logout on shared machines
+3. **Monitor sessions**: Check `bm cloud status` regularly
+4. **Revoke access**: Use account settings to revoke compromised tokens
+5. **Use HTTPS only**: Cloud commands enforce HTTPS
+

+
+## Technical Details
+
+### JWT Claims
+
+```json
+{
+  "sub": "user_abc123",
+  "org_id": "org_xyz789",
+  "tenant_id": "org_xyz789",
+  "subscription_status": "active",
+  "subscription_tier": "pro",
+  "exp": 1234567890,
+  "iat": 1234564290
+}
+```
+
+### API Integration
+
+The cloud API validates JWT on every request:
+
+```python
+# Middleware validates JWT and extracts tenant context
+@app.middleware("http")
+async def tenant_middleware(request: Request, call_next):
+    token = request.headers.get("Authorization")
+    claims = verify_jwt(token)
+    request.state.tenant_id = claims["tenant_id"]
+    request.state.subscription = claims["subscription_status"]
+    # ...
+```

+# Cloud Bidirectional Sync (SPEC-9)
+
+**Status**: New Feature
+**PR**: #322
+**Requires**: Active subscription, rclone installation
+
+## What's New
+
+v0.15.0 introduces **bidirectional cloud synchronization** using rclone bisync. Your local files sync automatically with the cloud, enabling multi-device workflows, backups, and collaboration.
+
+## Quick Start
+
+### One-Time Setup
+
+```bash
+# Install and configure cloud sync
+bm cloud bisync-setup
+
+# What it does:
+# 1. Installs rclone
+# 2. Gets tenant credentials
+# 3. Configures rclone remote
+# 4. Creates sync directory
+# 5. Performs initial sync
+```
+
+### Regular Sync
+
+```bash
+# Recommended: Use standard sync command
+bm sync                    # Syncs local → database
+bm cloud bisync            # Syncs local ↔ cloud
+
+# Or: Use watch mode (auto-sync every 60 seconds)
+bm sync --watch
+```
+
+## How Bidirectional Sync Works
+
+### Sync Architecture
+
+```
+Local Files          rclone bisync          Cloud Storage
+~/basic-memory-      <─────────────>       s3://bucket/
+cloud-sync/          (bidirectional)       tenant-id/
+  ├── project-a/                              ├── project-a/
+  ├── project-b/                              ├── project-b/
+  └── notes/                                  └── notes/
+```
+
+### Sync Profiles
+
+Three profiles optimize for different use cases:
+
+| Profile | Conflicts | Max Deletes | Speed | Use Case |
+|---------|-----------|-------------|-------|----------|
+| **safe** | Keep both versions | 10 | Slower | Preserve all changes, manual conflict resolution |
+| **balanced** | Use newer file | 25 | Medium | **Default** - auto-resolve most conflicts |
+| **fast** | Use newer file | 50 | Fastest | Rapid iteration, trust newer versions |
+
+### Conflict Resolution
+
+**safe profile** (--conflict-resolve=none):
+- Conflicting files saved as `file.conflict1`, `file.conflict2`
+- Manual resolution required
+- No data loss
+
+**balanced/fast profiles** (--conflict-resolve=newer):
+- Automatically uses the newer file
+- Faster syncs
+- Good for single-user workflows
+
+## Commands
+
+### bm cloud bisync-setup
+
+One-time setup for cloud sync.
+
+```bash
+bm cloud bisync-setup
+
+# Optional: Custom sync directory
+bm cloud bisync-setup --dir ~/my-sync-folder
+```
+
+**What happens:**
+1. Checks for/installs rclone
+2. Generates scoped S3 credentials
+3. Configures rclone remote
+4. Creates local sync directory
+5. Performs initial baseline sync (--resync)
+
+**Configuration saved to:**
+- `~/.basic-memory/config.json` - sync_dir path
+- `~/.config/rclone/rclone.conf` - remote credentials
+- `~/.basic-memory/bisync-state/{tenant_id}/` - sync state
+
+### bm cloud bisync
+
+Manual bidirectional sync.
+
+```bash
+# Basic sync (uses 'balanced' profile)
+bm cloud bisync
+
+# Choose sync profile
+bm cloud bisync --profile safe
+bm cloud bisync --profile balanced
+bm cloud bisync --profile fast
+
+# Dry run (preview changes)
+bm cloud bisync --dry-run
+
+# Force resync (rebuild baseline)
+bm cloud bisync --resync
+
+# Verbose output
+bm cloud bisync --verbose
+```
+
+**Auto-registration:**
+- Scans local directory for new projects
+- Creates them on cloud before sync
+- Ensures cloud knows about all local projects
+
+### bm sync (Recommended)
+
+The standard sync command now handles both local and cloud:
+
+```bash
+# One command for everything
+bm sync                    # Local sync + cloud sync
+bm sync --watch            # Continuous sync every 60s
+```
+
+## Sync Directory Structure
+
+### Default Layout
+
+```bash
+~/basic-memory-cloud-sync/     # Configurable via --dir
+├── project-a/                 # Auto-created local projects
+│   ├── notes/
+│   ├── ideas/
+│   └── .bmignore              # Respected during sync
+├── project-b/
+│   └── documents/
+└── .basic-memory/             # Metadata (ignored in sync)
+```
+
+### Important Paths
+
+| Path | Purpose |
+|------|---------|
+| `~/basic-memory-cloud-sync/` | Default local sync directory |
+| `~/basic-memory-cloud/` | Mount point (DO NOT use for bisync) |
+| `~/.basic-memory/bisync-state/{tenant_id}/` | Sync state and history |
+| `~/.basic-memory/.bmignore` | Patterns to exclude from sync |
+
+**Critical:** Bisync and mount must use **different directories**
+
+## File Filtering with .bmignore
+
+### Default Patterns
+
+Basic Memory respects `.bmignore` patterns (gitignore format):
+
+```bash
+# ~/.basic-memory/.bmignore (default)
+.git
+.DS_Store
+node_modules
+*.tmp
+.env
+__pycache__
+.pytest_cache
+.ruff_cache
+.vscode
+.idea
+```
+
+### How It Works
+
+1. `.bmignore` patterns converted to rclone filter format
+2. Auto-regenerated when `.bmignore` changes
+3. Stored as `~/.basic-memory/.bmignore.rclone`
+4. Applied to all bisync operations
+
+### Custom Patterns
+
+Edit `~/.basic-memory/.bmignore`:
+
+```bash
+# Your custom patterns
+.git
+*.log
+temp/
+*.backup
+```
+
+Next sync will use updated filters.
+
+## Project Management
+
+### Auto-Registration
+
+Bisync automatically registers new local projects:
+
+```bash
+# You create a new project locally
+mkdir ~/basic-memory-cloud-sync/new-project
+echo "# Hello" > ~/basic-memory-cloud-sync/new-project/README.md
+
+# Next sync auto-creates on cloud
+bm cloud bisync
+# → "Found 1 new local project, creating on cloud..."
+# → "✓ Created project: new-project"
+```
+
+### Project Discovery
+
+```bash
+# List cloud projects
+bm cloud status
+
+# Shows:
+# - Total projects
+# - Last sync time
+# - Storage used
+```
+
+### Cloud Mode
+
+To work with cloud projects via CLI:
+
+```bash
+# Set cloud API URL
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# Or in config.json:
+{
+  "api_url": "https://api.basicmemory.cloud"
+}
+
+# Now CLI tools work against cloud
+bm sync --project new-project        # Syncs cloud project
+bm tools continue-conversation --project new-project
+```
+
+## Sync Workflow Examples
+
+### Daily Workflow
+
+```bash
+# Morning: Start watch mode
+bm sync --watch &
+
+# Work in your sync directory
+cd ~/basic-memory-cloud-sync/work-notes
+vim ideas.md
+
+# Changes auto-sync every 60s
+# Watch output shows sync progress
+```
+
+### Multi-Device Workflow
+
+**Device A:**
+```bash
+# Make changes
+echo "# New Idea" > ~/basic-memory-cloud-sync/ideas/innovation.md
+
+# Sync to cloud
+bm cloud bisync
+# → "✓ Sync completed - 1 file uploaded"
+```
+
+**Device B:**
+```bash
+# Pull changes from cloud
+bm cloud bisync
+# → "✓ Sync completed - 1 file downloaded"
+
+# See the new file
+cat ~/basic-memory-cloud-sync/ideas/innovation.md
+# → "# New Idea"
+```
+
+### Conflict Scenario
+
+**Using balanced profile (auto-resolve):**
+
+```bash
+# Both devices edit same file
+# Device A: Updated at 10:00 AM
+# Device B: Updated at 10:05 AM
+
+# Device A syncs
+bm cloud bisync
+# → "✓ Sync completed"
+
+# Device B syncs
+bm cloud bisync
+# → "Resolving conflict: using newer version"
+# → "✓ Sync completed"
+# → Device B's version (10:05) wins
+```
+
+**Using safe profile (manual resolution):**
+
+```bash
+bm cloud bisync --profile safe
+# → "Conflict detected: ideas.md"
+# → "Saved as: ideas.md.conflict1 and ideas.md.conflict2"
+# → "Please resolve manually"
+
+# Review both versions
+diff ideas.md.conflict1 ideas.md.conflict2
+
+# Merge and cleanup
+vim ideas.md  # Merge manually
+rm ideas.md.conflict*
+```
+
+## Monitoring and Status
+
+### Check Sync Status
+
+```bash
+bm cloud status
+```
+
+**Shows:**
+```
+Cloud Bisync Status
+┏━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
+┃ Property            ┃ Value                      ┃

+└─────────────────────┴────────────────────────────┘
+```
+
+### Verify Integrity
+
+```bash
+bm cloud check
+```
+
+Compares local and cloud file hashes to detect:
+- Corrupted files
+- Missing files
+- Sync drift
+
+## Troubleshooting
+
+### "First bisync requires --resync"
+
+**Problem:** Initial sync not established
+
+```bash
+$ bm cloud bisync
+Error: First bisync requires --resync to establish baseline
+```
+
+**Solution:**
+```bash
+bm cloud bisync --resync
+```
+
+### "Cannot use mount directory for bisync"
+
+**Problem:** Trying to use mounted directory for sync
+
+```bash
+$ bm cloud bisync --dir ~/basic-memory-cloud
+Error: Cannot use ~/basic-memory-cloud for bisync - it's the mount directory!
+```
+
+**Solution:** Use different directory
+```bash
+bm cloud bisync --dir ~/basic-memory-cloud-sync
+```
+
+### Sync Conflicts
+
+**Problem:** Files modified on both sides
+
+**Safe profile (manual):**
+```bash
+# Find conflict files
+find ~/basic-memory-cloud-sync -name "*.conflict*"
+
+# Review and merge
+vimdiff file.conflict1 file.conflict2
+
+# Keep desired version
+mv file.conflict1 file
+rm file.conflict2
+```
+
+**Balanced profile (auto):**
+```bash
+# Already resolved to newer version
+# Check git history if needed
+cd ~/basic-memory-cloud-sync
+git log file.md
+```
+
+### Deleted Too Many Files
+
+**Problem:** Exceeds max_delete threshold
+
+```bash
+$ bm cloud bisync
+Error: Deletion exceeds safety limit (26 > 25)
+```
+
+**Solution:** Review deletions, then force if intentional
+```bash
+# Preview what would be deleted
+bm cloud bisync --dry-run
+
+# If intentional, use higher threshold profile
+bm cloud bisync --profile fast  # max_delete=50
+
+# Or resync to establish new baseline
+bm cloud bisync --resync
+```
+
+### rclone Not Found
+
+**Problem:** rclone not installed
+
+```bash
+$ bm cloud bisync
+Error: rclone not found
+```
+
+**Solution:**
+```bash
+# Run setup again
+bm cloud bisync-setup
+# → Installs rclone automatically
+```
+
+## Configuration
+
+### Bisync Config
+
+Edit `~/.basic-memory/config.json`:
+
+```json
+{
+  "bisync_config": {
+    "sync_dir": "~/basic-memory-cloud-sync",
+    "default_profile": "balanced",
+    "auto_sync_interval": 60
+  }
+}
+```
+
+### rclone Config
+
+Located at `~/.config/rclone/rclone.conf`:
+
+```ini
+[basic-memory-{tenant_id}]
+type = s3
+provider = AWS
+env_auth = false
+access_key_id = AKIA...
+secret_access_key = ***
+region = us-east-1
+endpoint = https://fly.storage.tigris.dev
+```
+
+**Security:** This file contains credentials - keep private (mode 600)
+
+## Performance Tips
+
+1. **Use balanced profile**: Best trade-off for most users
+2. **Enable watch mode**: `bm sync --watch` for auto-sync
+3. **Optimize .bmignore**: Exclude build artifacts and temp files
+4. **Batch changes**: Group related edits before sync
+5. **Use fast profile**: For rapid iteration on solo projects
+
+## Migration from WebDAV
+
+If upgrading from v0.14.x WebDAV:
+
+1. **Backup existing setup**
+   ```bash
+   cp -r ~/basic-memory ~/basic-memory.backup
+   ```
+
+2. **Run bisync setup**
+   ```bash
+   bm cloud bisync-setup
+   ```
+
+3. **Copy projects to sync directory**
+   ```bash
+   cp -r ~/basic-memory/* ~/basic-memory-cloud-sync/
+   ```
+
+4. **Initial sync**
+   ```bash
+   bm cloud bisync --resync
+   ```
+
+5. **Remove old WebDAV config** (if applicable)
+
+## Security
+
+- **Scoped credentials**: S3 credentials only access your tenant
+- **Encrypted transport**: All traffic over HTTPS/TLS
+- **No plain text secrets**: Credentials stored securely in rclone config
+- **File permissions**: Config files restricted to user (600)
+- **.bmignore**: Prevents syncing sensitive files

+# Using CLI Tools in Cloud Mode
+
+**Status**: DEPRECATED - Use `cloud_mode` instead of `api_url`
+**Related**: cloud-authentication.md, cloud-bisync.md
+
+## DEPRECATION NOTICE
+
+This document describes the old `api_url` / `BASIC_MEMORY_API_URL` approach which has been replaced by `cloud_mode` / `BASIC_MEMORY_CLOUD_MODE`.
+
+**New approach:** Use `cloud_mode` config or `BASIC_MEMORY_CLOUD_MODE` environment variable instead.
+
+## Quick Start
+
+### Enable Cloud Mode
+
+```bash
+# Set cloud API URL
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# Or in config.json
+{
+  "api_url": "https://api.basicmemory.cloud"
+}
+
+# Authenticate
+bm cloud login
+
+# Now CLI tools work against cloud
+bm sync --project my-cloud-project
+bm status
+bm tools search --query "notes"
+```
+
+## How It Works
+
+### Local vs Cloud Mode
+
+**Local Mode (default):**
+```
+CLI Tools → Local ASGI Transport → Local API → Local SQLite + Files
+```
+
+**Cloud Mode (with api_url set):**
+```
+CLI Tools → HTTP Client → Cloud API → Cloud SQLite + Cloud Files
+```
+
+### Mode Detection
+
+Basic Memory automatically detects mode:
+
+```python
+from basic_memory.config import ConfigManager
+
+config = ConfigManager().config
+
+if config.api_url:
+    # Cloud mode: use HTTP client
+    client = HTTPClient(base_url=config.api_url)
+else:
+    # Local mode: use ASGI transport
+    client = ASGITransport(app=api_app)
+```
+
+## Configuration
+
+### Via Environment Variable
+
+```bash
+# Set cloud API URL
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# All commands use cloud
+bm sync
+bm status
+```
+
+### Via Config File
+
+Edit `~/.basic-memory/config.json`:
+
+```json
+{
+  "api_url": "https://api.basicmemory.cloud",
+  "cloud_client_id": "client_abc123",
+  "cloud_domain": "https://auth.basicmemory.cloud",
+  "cloud_host": "https://api.basicmemory.cloud"
+}
+```
+
+### Temporary Override
+
+```bash
+# One-off cloud command
+BASIC_MEMORY_API_URL=https://api.basicmemory.cloud bm sync --project notes
+
+# Back to local mode
+bm sync --project notes
+```
+
+## Available Commands in Cloud Mode
+
+### Sync Commands
+
+```bash
+# Sync cloud project
+bm sync --project cloud-project
+
+# Sync specific project
+bm sync --project work-notes
+
+# Watch mode (cloud sync)
+bm sync --watch --project notes
+```
+
+### Status Commands
+
+```bash
+# Check cloud sync status
+bm status
+
+# Shows cloud project status
+```
+
+### MCP Tools
+
+```bash
+# Search in cloud project
+bm tools search \
+  --query "authentication" \
+  --project cloud-notes
+
+# Continue conversation from cloud
+bm tools continue-conversation \
+  --topic "search implementation" \
+  --project cloud-notes
+
+# Basic Memory guide
+bm tools basic-memory-guide
+```
+
+### Project Commands
+
+```bash
+# List cloud projects
+bm project list
+
+# Add cloud project (if permitted)
+bm project add notes /app/data/notes
+
+# Switch default project
+bm project default notes
+```
+
+## Workflows
+
+### Multi-Device Cloud Workflow
+
+**Device A (Primary):**
+```bash
+# Configure cloud mode
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# Authenticate
+bm cloud login
+
+# Use bisync for primary work
+bm cloud bisync-setup
+bm sync --watch
+
+# Local files in ~/basic-memory-cloud-sync/
+# Synced bidirectionally with cloud
+```
+
+**Device B (Secondary):**
+```bash
+# Configure cloud mode
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# Authenticate
+bm cloud login
+
+# Work directly with cloud (no local sync)
+bm tools search --query "meeting notes" --project work
+
+# Or mount for file access
+bm cloud mount
+```
+
+### Development vs Production
+
+**Development (local):**
+```bash
+# Local mode
+unset BASIC_MEMORY_API_URL
+
+# Work with local files
+bm sync
+bm tools search --query "test"
+```
+
+**Production (cloud):**
+```bash
+# Cloud mode
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# Work with cloud data
+bm sync --project production-kb
+```
+
+### Testing Cloud Integration
+
+```bash
+# Test against staging
+export BASIC_MEMORY_API_URL=https://staging-api.basicmemory.cloud
+bm cloud login
+bm sync --project test-project
+
+# Test against production
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+bm cloud login
+bm sync --project prod-project
+```
+
+## MCP Integration
+
+### Local MCP (default)
+
+```json
+// claude_desktop_config.json
+{
+  "mcpServers": {
+    "basic-memory": {
+      "command": "uvx",
+      "args": ["basic-memory", "mcp"]
+    }
+  }
+}
+```
+
+Uses local files via ASGI transport.
+
+### Cloud MCP
+
+```json
+// claude_desktop_config.json
+{
+  "mcpServers": {
+    "basic-memory-cloud": {
+      "command": "uvx",
+      "args": ["basic-memory", "mcp"],
+      "env": {
+        "BASIC_MEMORY_API_URL": "https://api.basicmemory.cloud"
+      }
+    }
+  }
+}
+```
+
+Uses cloud API via HTTP client.
+
+### Hybrid Setup (Both)
+
+```json
+{
+  "mcpServers": {
+    "basic-memory-local": {
+      "command": "uvx",
+      "args": ["basic-memory", "mcp"]
+    },
+    "basic-memory-cloud": {
+      "command": "uvx",
+      "args": ["basic-memory", "mcp"],
+      "env": {
+        "BASIC_MEMORY_API_URL": "https://api.basicmemory.cloud"
+      }
+    }
+  }
+}
+```
+
+Access both local and cloud from same LLM.
+
+## Authentication
+
+### Cloud Mode Requires Authentication
+
+```bash
+# Must login first
+bm cloud login
+
+# Then cloud commands work
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+bm sync --project notes
+```
+
+### Token Management
+
+Cloud mode uses JWT authentication:
+- Token stored in `~/.basic-memory/cloud-auth.json`
+- Auto-refreshed when expired
+- Includes subscription validation
+
+### Authentication Flow
+
+```bash
+# 1. Login
+bm cloud login
+# → Opens browser for OAuth
+# → Stores JWT token
+
+# 2. Set cloud mode
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# 3. Use tools (automatically authenticated)
+bm sync --project notes
+# → Sends Authorization: Bearer {token} header
+```
+
+## Project Management in Cloud Mode
+
+### Cloud Projects vs Local Projects
+
+**Local mode:**
+- Projects are local directories
+- Defined in `~/.basic-memory/config.json`
+- Full filesystem access
+
+**Cloud mode:**
+- Projects are cloud-managed
+- Retrieved from cloud API
+- Constrained by BASIC_MEMORY_PROJECT_ROOT on server
+
+### Working with Cloud Projects
+
+```bash
+# Enable cloud mode
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# List cloud projects
+bm project list
+# → Fetches from cloud API
+
+# Sync specific cloud project
+bm sync --project cloud-notes
+# → Syncs cloud project to cloud database
+
+# Search in cloud project
+bm tools search --query "auth" --project cloud-notes
+# → Searches cloud-indexed content
+```
+
+## Switching Between Local and Cloud
+
+### Switch to Cloud Mode
+
+```bash
+# Save local state
+bm sync  # Ensure local is synced
+
+# Switch to cloud
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+bm cloud login
+
+# Work with cloud
+bm sync --project cloud-project
+```
+
+### Switch to Local Mode
+
+```bash
+# Switch back to local
+unset BASIC_MEMORY_API_URL
+
+# Work with local files
+bm sync --project local-project
+```
+
+### Context-Aware Scripts
+
+```bash
+#!/bin/bash
+
+if [ -n "$BASIC_MEMORY_API_URL" ]; then
+  echo "Cloud mode: $BASIC_MEMORY_API_URL"
+  bm cloud login  # Ensure authenticated
+else
+  echo "Local mode"
+fi
+
+bm sync --project notes
+```
+
+## Performance Considerations
+
+### Network Latency
+
+Cloud mode requires network:
+- API calls over HTTPS
+- Latency depends on connection
+- Slower than local ASGI transport
+
+### Caching
+
+MCP in cloud mode has limited caching:
+- Results not cached locally
+- Each request hits cloud API
+- Consider using bisync for frequent access
+
+### Best Practices
+
+1. **Use bisync for primary work:**
+   ```bash
+   # Sync local copy
+   bm cloud bisync
+
+   # Work locally (fast)
+   unset BASIC_MEMORY_API_URL
+   bm tools search --query "notes"
+   ```
+
+2. **Use cloud mode for occasional access:**
+   ```bash
+   # Quick check from another device
+   export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+   bm tools search --query "meeting" --project work
+   ```
+
+3. **Hybrid approach:**
+   - Primary device: bisync for local work
+   - Other devices: cloud mode for quick access
+
+## Troubleshooting
+
+### Not Authenticated Error
+
+```bash
+$ bm sync --project notes
+Error: Not authenticated. Please run 'bm cloud login' first.
+```
+
+**Solution:**
+```bash
+bm cloud login
+```
+
+### Connection Refused
+
+```bash
+$ bm sync
+Error: Connection refused: https://api.basicmemory.cloud
+```
+
+**Solutions:**
+1. Check API URL: `echo $BASIC_MEMORY_API_URL`
+2. Verify network: `curl https://api.basicmemory.cloud/health`
+3. Check cloud status: https://status.basicmemory.com
+
+### Wrong Projects Listed
+
+**Problem:** `bm project list` shows unexpected projects
+
+**Check mode:**
+```bash
+# What mode am I in?
+echo $BASIC_MEMORY_API_URL
+
+# If set → cloud projects
+# If not set → local projects
+```
+
+**Solution:** Set/unset API_URL as needed
+
+### Subscription Required
+
+```bash
+$ bm sync --project notes
+Error: Active subscription required
+Subscribe at: https://basicmemory.com/subscribe
+```
+
+**Solution:** Subscribe or renew subscription
+
+## Configuration Examples
+
+### Development Setup
+
+```bash
+# .bashrc / .zshrc
+export BASIC_MEMORY_ENV=dev
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+
+# Local mode by default
+# Cloud mode on demand
+alias bm-cloud='BASIC_MEMORY_API_URL=https://api.basicmemory.cloud bm'
+```
+
+### Production Setup
+
+```bash
+# systemd service
+[Service]
+Environment="BASIC_MEMORY_API_URL=https://api.basicmemory.cloud"
+Environment="BASIC_MEMORY_LOG_LEVEL=INFO"
+ExecStart=/usr/local/bin/basic-memory serve
+```
+
+### Docker Setup
+
+```yaml
+# docker-compose.yml
+services:
+  basic-memory:
+    environment:
+      BASIC_MEMORY_API_URL: https://api.basicmemory.cloud
+      BASIC_MEMORY_LOG_LEVEL: INFO
+    volumes:
+      - ./cloud-auth:/root/.basic-memory/cloud-auth.json:ro
+```
+
+## Security
+
+### API Authentication
+
+- All cloud API calls authenticated with JWT
+- Token in Authorization header
+- Subscription validated per request
+
+### Network Security
+
+- All traffic over HTTPS/TLS
+- No credentials in URLs or logs
+- Tokens stored securely (mode 600)
+
+### Multi-Tenant Isolation
+
+- Tenant ID from JWT claims
+- Each request isolated to tenant
+- Cannot access other tenants' data

+# Cloud Mount Commands
+
+**Status**: New Feature
+**PR**: #306
+**Requires**: Active subscription, rclone installation
+
+## What's New
+
+v0.15.0 introduces cloud mount commands that let you access cloud storage as a local filesystem using rclone mount. This provides direct file access for browsing, editing, and working with cloud files.
+
+## Quick Start
+
+### Mount Cloud Storage
+
+```bash
+# Mount cloud storage at ~/basic-memory-cloud
+bm cloud mount
+
+# Storage now accessible as local directory
+ls ~/basic-memory-cloud
+cd ~/basic-memory-cloud/my-project
+vim notes.md
+```
+
+### Unmount
+
+```bash
+# Unmount when done
+bm cloud unmount
+```
+
+## How It Works
+
+### rclone Mount
+
+Basic Memory uses rclone to mount your cloud bucket as a FUSE filesystem:
+
+```
+Cloud Storage (S3)              rclone mount              Local Filesystem
+┌─────────────────┐                                      ┌──────────────────┐
+│ s3://bucket/    │            <───────────>             │ ~/basic-memory-  │
+│  tenant-id/     │          (FUSE filesystem)           │  cloud/          │
+│   ├── project-a/│                                      │   ├── project-a/ │
+│   ├── project-b/│                                      │   ├── project-b/ │
+│   └── notes/    │                                      │   └── notes/     │
+└─────────────────┘                                      └──────────────────┘
+```
+
+### Mount vs Bisync
+
+| Feature | Mount | Bisync |
+|---------|-------|--------|
+| **Access** | Direct cloud access | Synced local copy |
+| **Latency** | Network dependent | Instant (local files) |
+| **Offline** | Requires connection | Works offline |
+| **Storage** | No local storage | Uses local disk |
+| **Use Case** | Quick access, browsing | Primary workflow, offline work |
+
+**Key difference:** Mount directory (`~/basic-memory-cloud`) and bisync directory (`~/basic-memory-cloud-sync`) must be **different locations**.
+
+## Commands
+
+### bm cloud mount
+
+Mount cloud storage to local filesystem.
+
+```bash
+# Basic mount (default: ~/basic-memory-cloud)
+bm cloud mount
+
+# Custom mount point
+bm cloud mount --mount-point ~/my-cloud-mount
+
+# Background mode
+bm cloud mount --daemon
+
+# With verbose logging
+bm cloud mount --verbose
+```
+
+**What happens:**
+1. Authenticates with cloud (uses stored JWT)
+2. Generates scoped S3 credentials
+3. Configures rclone remote
+4. Mounts cloud bucket via FUSE
+5. Makes files accessible at mount point
+
+### bm cloud unmount
+
+Unmount cloud storage.
+
+```bash
+# Unmount default location
+bm cloud unmount
+
+# Unmount custom location
+bm cloud unmount --mount-point ~/my-cloud-mount
+
+# Force unmount (if busy)
+bm cloud unmount --force
+```
+
+**What happens:**
+1. Flushes pending writes
+2. Unmounts FUSE filesystem
+3. Cleans up mount point
+
+### bm cloud status
+
+Check mount status.
+
+```bash
+bm cloud status
+```
+
+**Shows:**
+```
+Cloud Mount Status
+┏━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓

+
+### Default Layout
+
+```bash
+~/basic-memory-cloud/              # Mount point (configurable)
+├── project-a/                     # Cloud projects visible as directories

+```
+
+### Important: Separate from Bisync
+
+**Mount point:** `~/basic-memory-cloud` (direct cloud access)
+**Bisync directory:** `~/basic-memory-cloud-sync` (synced local copy)
+
+**These MUST be different directories:**
+```bash
+# ✓ Correct - different directories
+MOUNT: ~/basic-memory-cloud
+BISYNC: ~/basic-memory-cloud-sync
+
+# ✗ Wrong - same directory (will error)
+MOUNT: ~/basic-memory-cloud
+BISYNC: ~/basic-memory-cloud
+```
+
+## Usage Workflows
+
+### Quick File Access
+
+```bash
+# Mount
+bm cloud mount
+
+# Browse files
+ls ~/basic-memory-cloud
+cd ~/basic-memory-cloud/work-project
+
+# View a file
+cat ideas/new-feature.md
+
+# Edit directly
+vim notes/meeting.md
+
+# Unmount when done
+bm cloud unmount
+```
+
+### Read-Only Browsing
+
+```bash
+# Mount for reading
+bm cloud mount
+
+# Search for files
+grep -r "authentication" ~/basic-memory-cloud
+
+# View recent files
+find ~/basic-memory-cloud -type f -mtime -7
+
+# Unmount
+bm cloud unmount
+```
+
+### Working with Obsidian
+
+```bash
+# Mount cloud storage
+bm cloud mount
+
+# Open mount point in Obsidian
+# Obsidian vault: ~/basic-memory-cloud/my-project
+
+# Work directly on cloud files
+# Changes saved immediately to cloud
+
+# Unmount when done (close Obsidian first)
+bm cloud unmount
+```
+
+### Temporary Access on Another Device
+
+```bash
+# Device B (no local sync setup)
+bm cloud login
+bm cloud mount
+
+# Access files directly
+cd ~/basic-memory-cloud
+vim project/notes.md
+
+# Unmount and logout
+bm cloud unmount
+bm cloud logout
+```
+
+## Performance Considerations
+
+### Network Latency
+
+Mount performance depends on network:
+- **Local network:** Fast, near-native performance
+- **Remote/internet:** Slower, noticeable latency
+- **Offline:** Not accessible (returns errors)
+
+### Caching
+
+rclone provides some caching:
+```bash
+# Mount with enhanced caching
+rclone mount basic-memory-remote:bucket ~/basic-memory-cloud \
+  --vfs-cache-mode writes \
+  --vfs-write-back 5s
+```
+
+### When to Use Mount vs Bisync
+
+**Use Mount for:**
+- Quick file access
+- Temporary access on other devices
+- Read-only browsing
+- Low disk space situations
+
+**Use Bisync for:**
+- Primary workflow
+- Offline access
+- Better performance
+- Regular file operations
+
+## Mount Options
+
+### Foreground vs Daemon
+
+**Foreground (default):**
+```bash
+bm cloud mount
+# Runs in foreground, shows logs
+# Ctrl+C to unmount
+```
+
+**Daemon (background):**
+```bash
+bm cloud mount --daemon
+# Runs in background
+# Use 'bm cloud unmount' to stop
+```
+
+### Read-Only Mount
+
+```bash
+# Mount as read-only
+bm cloud mount --read-only
+
+# Prevents accidental changes
+# Good for browsing/searching
+```
+
+### Custom Mount Point
+
+```bash
+# Use different directory
+bm cloud mount --mount-point ~/cloud-kb
+
+# Files at ~/cloud-kb/
+ls ~/cloud-kb
+```
+
+## Troubleshooting
+
+### Mount Failed
+
+**Problem:** Can't mount cloud storage
+
+```bash
+$ bm cloud mount
+Error: mount failed: transport endpoint not connected
+```
+
+**Solutions:**
+1. Check authentication: `bm cloud login`
+2. Verify rclone installed: `which rclone`
+3. Check mount point exists: `mkdir -p ~/basic-memory-cloud`
+4. Ensure not already mounted: `bm cloud unmount`
+
+### Directory Busy
+
+**Problem:** Can't unmount, directory in use
+
+```bash
+$ bm cloud unmount
+Error: device is busy
+```
+
+**Solutions:**
+```bash
+# Check what's using it
+lsof | grep basic-memory-cloud
+
+# Close applications using mount
+# cd out of mount directory
+cd ~
+
+# Force unmount
+bm cloud unmount --force
+
+# Or use system unmount
+umount -f ~/basic-memory-cloud
+```
+
+### Permission Denied
+
+**Problem:** Can't access mounted files
+
+```bash
+$ ls ~/basic-memory-cloud
+Permission denied
+```
+
+**Solutions:**
+1. Check credentials: `bm cloud login`
+2. Verify subscription: `bm cloud status`
+3. Remount: `bm cloud unmount && bm cloud mount`
+
+### Slow Performance
+
+**Problem:** Files load slowly
+
+**Solutions:**
+1. Use bisync for regular work instead
+2. Enable write caching (advanced)
+3. Check network connection
+4. Consider local-first workflow
+
+### Conflicts with Bisync
+
+**Problem:** Trying to use same directory
+
+```bash
+$ bm cloud mount --mount-point ~/basic-memory-cloud-sync
+Error: Cannot use bisync directory for mount
+```
+
+**Solution:** Use different directories
+```bash
+MOUNT: ~/basic-memory-cloud
+BISYNC: ~/basic-memory-cloud-sync
+```
+
+## Advanced Usage
+
+### Manual rclone Mount
+
+For advanced users, mount directly:
+
+```bash
+# List configured remotes
+rclone listremotes
+
+# Manual mount with options
+rclone mount basic-memory-{tenant-id}:{bucket} ~/mount-point \
+  --vfs-cache-mode full \
+  --vfs-cache-max-age 1h \
+  --daemon
+
+# Unmount
+fusermount -u ~/mount-point  # Linux
+umount ~/mount-point         # macOS
+```
+
+### Mount with Specific Options
+
+```bash
+# Read-only with caching
+rclone mount remote:bucket ~/mount \
+  --read-only \
+  --vfs-cache-mode full
+
+# Write-back for better performance
+rclone mount remote:bucket ~/mount \
+  --vfs-cache-mode writes \
+  --vfs-write-back 30s
+```
+
+## Platform-Specific Notes
+
+### macOS
+
+**Requires:** macFUSE
+```bash
+# Install macFUSE
+brew install --cask macfuse
+
+# Mount
+bm cloud mount
+```
+
+**Unmount:**
+```bash
+# Basic
+bm cloud unmount
+
+# Or system unmount
+umount ~/basic-memory-cloud
+```
+
+### Linux
+
+**Requires:** FUSE
+```bash
+# Install FUSE (usually pre-installed)
+sudo apt-get install fuse  # Debian/Ubuntu
+sudo yum install fuse      # RHEL/CentOS
+
+# Mount
+bm cloud mount
+```
+
+**Unmount:**
+```bash
+# Basic
+bm cloud unmount
+
+# Or system unmount
+fusermount -u ~/basic-memory-cloud
+```
+
+### Windows
+
+**Requires:** WinFsp
+```bash
+# Install WinFsp from https://winfsp.dev/
+
+# Mount
+bm cloud mount
+
+# Mounted as drive letter (e.g., Z:)
+dir Z:\
+```
+
+## Security
+
+### Credentials
+
+- Mount uses scoped S3 credentials (tenant-isolated)
+- Credentials expire after session
+- No plain-text secrets stored
+
+### File Access
+
+- All traffic encrypted (HTTPS/TLS)
+- Same permissions as cloud API
+- Respects tenant isolation
+
+### Unmount on Logout
+
+```bash
+# Good practice: unmount before logout
+bm cloud unmount
+bm cloud logout
+```

+# Default Project Mode
+
+**Status**: New Feature
+**PR**: #298 (SPEC-6)
+**Related**: explicit-project-parameter.md
+
+## What's New
+
+v0.15.0 introduces `default_project_mode` - a configuration option that simplifies single-project workflows by automatically using your default project when no explicit project parameter is provided.
+
+## Quick Start
+
+### Enable Default Project Mode
+
+Edit `~/.basic-memory/config.json`:
+
+```json
+{
+  "default_project": "main",
+  "default_project_mode": true,
+  "projects": {
+    "main": "/Users/you/basic-memory"
+  }
+}
+```
+
+### Now Tools Work Without Project Parameter
+
+```python
+# Before (explicit project required)
+await write_note("Note", "Content", "folder", project="main")
+
+# After (with default_project_mode: true)
+await write_note("Note", "Content", "folder")  # Uses "main" automatically
+```
+
+## Configuration Options
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `default_project_mode` | boolean | `false` | Enable auto-fallback to default project |
+| `default_project` | string | `"main"` | Which project to use as default |
+
+## How It Works
+
+### Three-Tier Project Resolution
+
+When a tool is called, Basic Memory resolves the project in this order:
+
+1. **CLI Constraint** (Highest): `bm --project work-notes` forces all tools to use "work-notes"
+2. **Explicit Parameter** (Medium): `project="specific"` in tool call
+3. **Default Mode** (Lowest): Uses `default_project` if `default_project_mode: true`
+
+### Examples
+
+**With default_project_mode: false (default):**
+```python
+# Must specify project explicitly
+await search_notes("query", project="main")  # ✓ Works
+await search_notes("query")                  # ✗ Error: project required
+```
+
+**With default_project_mode: true:**
+```python
+# Project parameter is optional
+await search_notes("query")                  # ✓ Uses default_project
+await search_notes("query", project="work")  # ✓ Explicit override works
+```
+
+## Use Cases
+
+### Single-Project Users
+
+**Best for:**
+- Users who maintain one primary knowledge base
+- Personal knowledge management
+- Single-purpose documentation
+
+**Configuration:**
+```json
+{
+  "default_project": "main",
+  "default_project_mode": true,
+  "projects": {
+    "main": "/Users/you/basic-memory"
+  }
+}
+```
+
+**Benefits:**
+- Simpler tool calls
+- Less verbose for AI assistants
+- Familiar workflow (like v0.14.x)
+
+### Multi-Project Users
+
+**Best for:**
+- Multiple distinct knowledge bases (work, personal, research)
+- Switching contexts frequently
+- Team collaboration with separate projects
+
+**Configuration:**
+```json
+{
+  "default_project": "main",
+  "default_project_mode": false,
+  "projects": {
+    "work": "/Users/you/work-kb",
+    "personal": "/Users/you/personal-kb",
+    "research": "/Users/you/research-kb"
+  }
+}
+```
+
+**Benefits:**
+- Explicit project selection prevents mistakes
+- Clear which knowledge base is being accessed
+- Better for context switching
+
+## Workflow Examples
+
+### Single-Project Workflow
+
+```python
+# config.json: default_project_mode: true, default_project: "main"
+
+# Write without specifying project
+await write_note(
+    title="Meeting Notes",
+    content="# Team Sync\n...",
+    folder="meetings"
+)  # → Saved to "main" project
+
+# Search across default project
+results = await search_notes("quarterly goals")
+# → Searches "main" project
+
+# Build context from default project
+context = await build_context("memory://goals/q4-2024")
+# → Uses "main" project
+```
+
+### Multi-Project with Explicit Selection
+
+```python
+# config.json: default_project_mode: false
+
+# Work project
+await write_note(
+    title="Architecture Decision",
+    content="# ADR-001\n...",
+    folder="decisions",
+    project="work"
+)
+
+# Personal project
+await write_note(
+    title="Book Notes",
+    content="# Design Patterns\n...",
+    folder="reading",
+    project="personal"
+)
+
+# Research project
+await search_notes(
+    query="machine learning",
+    project="research"
+)
+```
+
+### Hybrid: Default with Occasional Override
+
+```python
+# config.json: default_project_mode: true, default_project: "personal"
+
+# Most operations use personal (default)
+await write_note("Daily Journal", "...", "journal")
+# → Saved to "personal"
+
+# Explicitly use work project when needed
+await write_note(
+    title="Sprint Planning",
+    content="...",
+    folder="planning",
+    project="work"  # Override default
+)
+# → Saved to "work"
+
+# Back to default
+await search_notes("goals")
+# → Searches "personal"
+```
+
+## Migration Guide
+
+### From v0.14.x (Implicit Project)
+
+v0.14.x had implicit project context via middleware. To get similar behavior:
+
+**Enable default_project_mode:**
+```json
+{
+  "default_project": "main",
+  "default_project_mode": true
+}
+```
+
+Now tools work without explicit project parameter (like v0.14.x).
+
+### From v0.15.0 Explicit-Only
+
+If you started with v0.15.0 using explicit projects:
+
+**Keep current behavior:**
+```json
+{
+  "default_project_mode": false  # or omit (false is default)
+}
+```
+
+**Or simplify for single project:**
+```json
+{
+  "default_project": "main",
+  "default_project_mode": true
+}
+```
+
+## LLM Integration
+
+### Claude Desktop
+
+Claude can detect and use default_project_mode:
+
+**Auto-detection:**
+```python
+# Claude reads config
+config = read_config()
+
+if config.get("default_project_mode"):
+    # Use simple calls
+    await write_note("Note", "Content", "folder")
+else:
+    # Discover and use explicit project
+    projects = await list_memory_projects()
+    await write_note("Note", "Content", "folder", project=projects[0].name)
+```
+
+### Custom MCP Clients
+
+```python
+from basic_memory.config import ConfigManager
+
+config = ConfigManager().config
+
+if config.default_project_mode:
+    # Project parameter optional
+    result = await mcp_tool(arg1, arg2)
+else:
+    # Project parameter required
+    result = await mcp_tool(arg1, arg2, project="name")
+```
+
+## Error Handling
+
+### Missing Project (default_project_mode: false)
+
+```python
+try:
+    results = await search_notes("query")
+except ValueError as e:
+    print("Error: project parameter required")
+    # Show available projects
+    projects = await list_memory_projects()
+    print(f"Available: {[p.name for p in projects]}")
+```
+
+### Invalid Default Project
+
+```json
+{
+  "default_project": "nonexistent",
+  "default_project_mode": true
+}
+```
+
+**Result:** Falls back to "main" project if default doesn't exist.
+
+## Configuration Management
+
+### Update Config
+
+```bash
+# Edit directly
+vim ~/.basic-memory/config.json
+
+# Or use CLI (if available)
+bm config set default_project_mode true
+bm config set default_project main
+```
+
+### Verify Config
+
+```python
+from basic_memory.config import ConfigManager
+
+config = ConfigManager().config
+print(f"Default mode: {config.default_project_mode}")
+print(f"Default project: {config.default_project}")
+print(f"Projects: {list(config.projects.keys())}")
+```
+
+### Environment Override
+
+```bash
+# Override via environment
+export BASIC_MEMORY_DEFAULT_PROJECT_MODE=true
+export BASIC_MEMORY_DEFAULT_PROJECT=work
+
+# Now default_project_mode enabled for this session
+```
+
+## Best Practices
+
+1. **Choose based on workflow:**
+   - Single project → enable default_project_mode
+   - Multiple projects → keep explicit (false)
+
+2. **Document your choice:**
+   - Add comment to config.json explaining why
+
+3. **Consistent with team:**
+   - Agree on project mode for shared setups
+
+4. **Test both modes:**
+   - Try each to see what feels natural
+
+5. **Use CLI constraints when needed:**
+   - `bm --project work-notes` overrides everything
+
+## Troubleshooting
+
+### Tools Not Using Default Project
+
+**Problem:** default_project_mode: true but tools still require project
+
+**Check:**
+```bash
+# Verify config
+cat ~/.basic-memory/config.json | grep default_project_mode
+
+# Should show: "default_project_mode": true
+```
+
+**Solution:** Restart MCP server to reload config
+
+### Wrong Project Being Used
+
+**Problem:** Tools using unexpected project
+
+**Check resolution order:**
+1. CLI constraint (`--project` flag)
+2. Explicit parameter in tool call
+3. Default project (if mode enabled)
+
+**Solution:** Check for CLI constraints or explicit parameters
+
+### Config Not Loading
+
+**Problem:** Changes to config.json not taking effect
+
+**Solution:**
+```bash
+# Restart MCP server
+# Or reload config programmatically
+from basic_memory import config as config_module
+config_module._config = None  # Clear cache
+```
+
+## Technical Details
+
+### Implementation
+
+```python
+class BasicMemoryConfig(BaseSettings):
+    default_project: str = Field(
+        default="main",
+        description="Name of the default project to use"
+    )
+
+    default_project_mode: bool = Field(
+        default=False,
+        description="When True, MCP tools automatically use default_project when no project parameter is specified"
+    )
+```
+
+### Project Resolution Logic
+
+```python
+def resolve_project(
+    explicit_project: Optional[str] = None,
+    cli_project: Optional[str] = None,
+    config: BasicMemoryConfig = None
+) -> str:
+    # 1. CLI constraint (highest priority)
+    if cli_project:
+        return cli_project
+
+    # 2. Explicit parameter
+    if explicit_project:
+        return explicit_project
+
+    # 3. Default mode (lowest priority)
+    if config.default_project_mode:
+        return config.default_project
+
+    # 4. No project found
+    raise ValueError("Project parameter required")
+```

+# .env File Loading Removed
+
+**Status**: Security Fix
+**PR**: #330
+**Impact**: Breaking change for users relying on .env files
+
+## What Changed
+
+v0.15.0 **removes automatic .env file loading** from Basic Memory configuration. Environment variables must now be set explicitly through your shell, systemd, Docker, or other standard mechanisms.
+
+### Before v0.15.0
+
+```python
+# BasicMemoryConfig automatically loaded .env files
+from dotenv import load_dotenv
+load_dotenv()  # ← Automatically loaded .env
+
+config = BasicMemoryConfig()  # ← Used .env values
+```
+
+### v0.15.0 and Later
+
+```python
+# No automatic .env loading
+config = BasicMemoryConfig()  # ← Only uses actual environment variables
+```
+
+## Why This Changed
+
+### Security Vulnerability
+
+Automatic .env loading created security risks:
+
+1. **Unintended file loading:**
+   - Could load `.env` from current directory
+   - Could load `.env` from parent directories
+   - Risk of loading untrusted `.env` files
+
+2. **Credential leakage:**
+   - `.env` files might contain secrets
+   - Easy to accidentally commit to git
+   - Hard to audit what's loaded
+
+3. **Configuration confusion:**
+   - Unclear which values come from `.env` vs environment
+   - Debugging difficult with implicit loading
+
+### Best Practice
+
+Modern deployment practices use explicit environment configuration:
+- Shell exports
+- systemd Environment directives
+- Docker environment variables
+- Kubernetes ConfigMaps/Secrets
+- CI/CD variable injection
+
+## Migration Guide
+
+### If You Used .env Files
+
+**Step 1: Check if you have a .env file**
+```bash
+ls -la .env
+ls -la ~/.basic-memory/.env
+```
+
+**Step 2: Review .env contents**
+```bash
+cat .env
+```
+
+**Step 3: Convert to explicit environment variables**
+
+**Option A: Shell exports (development)**
+```bash
+# Move values from .env to shell config
+# .bashrc or .zshrc
+
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_DEFAULT_PROJECT=main
+```
+
+**Option B: direnv (recommended for development)**
+```bash
+# Install direnv
+brew install direnv  # macOS
+sudo apt install direnv  # Linux
+
+# Create .envrc (git-ignored)
+cat > .envrc <<EOF
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+EOF
+
+# Allow direnv for this directory
+direnv allow
+
+# Auto-loads when entering directory
+```
+
+**Option C: systemd (production)**
+```ini
+# /etc/systemd/system/basic-memory.service
+[Service]
+Environment="BASIC_MEMORY_PROJECT_ROOT=/var/lib/basic-memory"
+Environment="BASIC_MEMORY_LOG_LEVEL=INFO"
+ExecStart=/usr/local/bin/basic-memory serve
+```
+
+**Option D: Docker (containers)**
+```yaml
+# docker-compose.yml
+services:
+  basic-memory:
+    environment:
+      BASIC_MEMORY_PROJECT_ROOT: /app/data
+      BASIC_MEMORY_LOG_LEVEL: INFO
+```
+
+### If You Didn't Use .env Files
+
+No action needed - your setup already uses explicit environment variables.
+
+## Alternative Solutions
+
+### Development: Use direnv
+
+[direnv](https://direnv.net/) automatically loads environment variables when entering a directory:
+
+**Setup:**
+```bash
+# Install
+brew install direnv
+
+# Add to shell (.bashrc or .zshrc)
+eval "$(direnv hook bash)"  # or zsh
+
+# Create .envrc in project
+cat > .envrc <<EOF
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_PROJECT_ROOT=\$PWD/data
+EOF
+
+# Git-ignore it
+echo ".envrc" >> .gitignore
+
+# Allow it
+direnv allow
+```
+
+**Usage:**
+```bash
+# Entering directory auto-loads variables
+cd ~/my-project
+# → direnv: loading .envrc
+# → direnv: export +BASIC_MEMORY_LOG_LEVEL +BASIC_MEMORY_PROJECT_ROOT
+
+# Check variables
+env | grep BASIC_MEMORY_
+```
+
+### Production: External Configuration
+
+**AWS Systems Manager:**
+```bash
+# Store in Parameter Store
+aws ssm put-parameter \
+  --name /basic-memory/project-root \
+  --value /app/data \
+  --type SecureString
+
+# Retrieve and export
+export BASIC_MEMORY_PROJECT_ROOT=$(aws ssm get-parameter \
+  --name /basic-memory/project-root \
+  --with-decryption \
+  --query Parameter.Value \
+  --output text)
+```
+
+**Kubernetes Secrets:**
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: basic-memory-env
+stringData:
+  BASIC_MEMORY_PROJECT_ROOT: /app/data
+---

+```bash
+# Store in Vault
+vault kv put secret/basic-memory \
+  project_root=/app/data \
+  log_level=INFO
+
+# Retrieve and export
+export BASIC_MEMORY_PROJECT_ROOT=$(vault kv get -field=project_root secret/basic-memory)
+```
+
+## Security Best Practices
+
+### 1. Never Commit Environment Files
+
+**Always git-ignore:**
+```bash
+# .gitignore
+.env
+.env.*
+.envrc
+*.env
+cloud-auth.json
+```
+
+### 2. Use Secret Management
+
+**For sensitive values:**
+- AWS Secrets Manager
+- HashiCorp Vault
+- Kubernetes Secrets
+- Azure Key Vault
+- Google Secret Manager
+
+### 3. Scope Secrets Appropriately
+
+**Development:**
+```bash
+# Development secrets (less sensitive)
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_PROJECT_ROOT=~/dev/data
+```
+
+**Production:**
+```bash
+# Production secrets (highly sensitive)
+export BASIC_MEMORY_CLOUD_SECRET_KEY=$(fetch-from-vault)
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+```
+
+### 4. Audit Environment Variables
+
+**Log non-sensitive vars:**
+```python
+import os
+from loguru import logger
+
+# Safe to log
+safe_vars = {
+    k: v for k, v in os.environ.items()
+    if k.startswith("BASIC_MEMORY_") and "SECRET" not in k
+}
+logger.info(f"Config loaded with: {safe_vars}")
+
+# Never log
+secret_vars = [k for k in os.environ.keys() if "SECRET" in k or "KEY" in k]
+logger.debug(f"Secret vars present: {len(secret_vars)}")
+```
+
+### 5. Principle of Least Privilege
+
+```bash
+# ✓ Good: Minimal permissions
+export BASIC_MEMORY_PROJECT_ROOT=/app/data/tenant-123  # Scoped to tenant
+
+# ✗ Bad: Too permissive
+export BASIC_MEMORY_PROJECT_ROOT=/  # Entire filesystem
+```
+
+## Troubleshooting
+
+### Variables Not Loading
+
+**Problem:** Settings not taking effect after migration
+
+**Check:**
+```bash
+# Are variables actually exported?
+env | grep BASIC_MEMORY_
+
+# Not exported (wrong)
+BASIC_MEMORY_LOG_LEVEL=DEBUG  # Missing 'export'
+
+# Exported (correct)
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+```
+
+### .env Still Present
+
+**Problem:** Old .env file exists but ignored
+
+**Solution:**
+```bash
+# Review and remove
+cat .env  # Check contents
+rm .env   # Remove after migrating
+
+# Ensure git-ignored
+echo ".env" >> .gitignore
+```
+
+### Different Behavior After Upgrade
+
+**Problem:** Config different after v0.15.0
+
+**Check for .env usage:**
+```bash
+# Did you have .env?
+git log --all --full-history -- .env
+
+# If yes, migrate values to explicit env vars
+```
+
+## Configuration Checklist
+
+After removing .env files, verify:
+
+- [ ] All required env vars exported explicitly
+- [ ] .env files removed or git-ignored
+- [ ] Production uses systemd/Docker/K8s env vars
+- [ ] Development uses direnv or shell config
+- [ ] Secrets stored in secret manager (not env files)
+- [ ] No credentials committed to git
+- [ ] Documentation updated with new approach
+
+## Example Configurations
+
+### Local Development
+
+**~/.bashrc or ~/.zshrc:**
+```bash
+# Basic Memory configuration
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_PROJECT_ROOT=~/dev/basic-memory
+export BASIC_MEMORY_DEFAULT_PROJECT=main
+export BASIC_MEMORY_DEFAULT_PROJECT_MODE=true
+```
+
+### Docker Development
+
+**docker-compose.yml:**
+```yaml
+services:
+  basic-memory:
+    image: basic-memory:latest
+    environment:
+      BASIC_MEMORY_LOG_LEVEL: DEBUG
+      BASIC_MEMORY_PROJECT_ROOT: /app/data
+      BASIC_MEMORY_HOME: /app/data/basic-memory
+    volumes:
+      - ./data:/app/data
+```
+
+### Production Deployment
+
+**systemd service:**
+```ini

+Description=Basic Memory Service
+
+[Service]
+Type=simple

+```
+
+### Kubernetes Production

+# Environment Variable Overrides
+
+**Status**: Fixed in v0.15.0
+**PR**: #334 (part of PROJECT_ROOT implementation)
+
+## What Changed
+
+v0.15.0 fixes configuration loading to properly respect environment variable overrides. Environment variables with the `BASIC_MEMORY_` prefix now correctly override values in `config.json`.
+
+## How It Works
+
+### Precedence Order (Highest to Lowest)
+
+1. **Environment Variables** (`BASIC_MEMORY_*`)
+2. **Config File** (`~/.basic-memory/config.json`)
+3. **Default Values** (Built-in defaults)
+
+### Example
+
+```bash
+# config.json contains:
+{
+  "default_project": "main",
+  "log_level": "INFO"
+}
+
+# Environment overrides:
+export BASIC_MEMORY_DEFAULT_PROJECT=work
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+
+# Result:
+# default_project = "work"     ← from env var
+# log_level = "DEBUG"           ← from env var
+```
+
+## Environment Variable Naming
+
+All environment variables use the prefix `BASIC_MEMORY_` followed by the config field name in UPPERCASE:
+
+| Config Field | Environment Variable | Example |
+|--------------|---------------------|---------|
+| `default_project` | `BASIC_MEMORY_DEFAULT_PROJECT` | `BASIC_MEMORY_DEFAULT_PROJECT=work` |
+| `log_level` | `BASIC_MEMORY_LOG_LEVEL` | `BASIC_MEMORY_LOG_LEVEL=DEBUG` |
+| `project_root` | `BASIC_MEMORY_PROJECT_ROOT` | `BASIC_MEMORY_PROJECT_ROOT=/app/data` |
+| `api_url` | `BASIC_MEMORY_API_URL` | `BASIC_MEMORY_API_URL=https://api.example.com` |
+| `default_project_mode` | `BASIC_MEMORY_DEFAULT_PROJECT_MODE` | `BASIC_MEMORY_DEFAULT_PROJECT_MODE=true` |
+
+## Common Use Cases
+
+### Development vs Production
+
+**Development (.env or shell):**
+```bash
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_API_URL=http://localhost:8000
+```
+
+**Production (systemd/docker):**
+```bash
+export BASIC_MEMORY_LOG_LEVEL=INFO
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+```
+
+### CI/CD Pipelines
+
+```bash
+# GitHub Actions
+env:
+  BASIC_MEMORY_ENV: test
+  BASIC_MEMORY_LOG_LEVEL: DEBUG
+
+# GitLab CI
+variables:
+  BASIC_MEMORY_ENV: test
+  BASIC_MEMORY_PROJECT_ROOT: /builds/project/data
+```
+
+### Docker Deployments
+
+```bash
+# docker run
+docker run \
+  -e BASIC_MEMORY_HOME=/app/data/main \
+  -e BASIC_MEMORY_PROJECT_ROOT=/app/data \
+  -e BASIC_MEMORY_LOG_LEVEL=INFO \
+  basic-memory:latest
+
+# docker-compose.yml
+services:
+  basic-memory:
+    environment:
+      BASIC_MEMORY_HOME: /app/data/main
+      BASIC_MEMORY_PROJECT_ROOT: /app/data
+      BASIC_MEMORY_LOG_LEVEL: INFO
+```
+
+### Kubernetes
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: basic-memory-env
+data:
+  BASIC_MEMORY_LOG_LEVEL: "INFO"
+  BASIC_MEMORY_PROJECT_ROOT: "/app/data"
+---
+apiVersion: apps/v1

+spec:
+  template:
+    spec:
+      containers:
+      - name: basic-memory
+        envFrom:
+        - configMapRef:
+            name: basic-memory-env
+```
+
+## Available Environment Variables
+
+### Core Configuration
+
+```bash
+# Environment mode
+export BASIC_MEMORY_ENV=user              # test, dev, user
+
+# Project configuration

+export BASIC_MEMORY_DEFAULT_PROJECT_MODE=true
+
+# Path constraints
+export BASIC_MEMORY_HOME=/path/to/main
+export BASIC_MEMORY_PROJECT_ROOT=/path/to/root
+```
+
+### Sync Configuration
+
+```bash
+# Sync behavior
+export BASIC_MEMORY_SYNC_CHANGES=true
+export BASIC_MEMORY_SYNC_DELAY=1000
+export BASIC_MEMORY_SYNC_THREAD_POOL_SIZE=4
+
+# Watch service
+export BASIC_MEMORY_WATCH_PROJECT_RELOAD_INTERVAL=30
+```
+
+### Feature Flags
+
+```bash
+# Permalinks
+export BASIC_MEMORY_UPDATE_PERMALINKS_ON_MOVE=false
+export BASIC_MEMORY_DISABLE_PERMALINKS=false
+export BASIC_MEMORY_KEBAB_FILENAMES=false
+
+# Performance
+export BASIC_MEMORY_SKIP_INITIALIZATION_SYNC=false
+```
+
+### API Configuration
+
+```bash
+# Remote API
+export BASIC_MEMORY_API_URL=https://api.basicmemory.cloud
+
+# Cloud configuration
+export BASIC_MEMORY_CLOUD_CLIENT_ID=client_abc123
+export BASIC_MEMORY_CLOUD_DOMAIN=https://auth.example.com
+export BASIC_MEMORY_CLOUD_HOST=https://api.example.com
+```
+
+### Logging
+
+```bash
+# Log level
+export BASIC_MEMORY_LOG_LEVEL=DEBUG       # DEBUG, INFO, WARNING, ERROR
+```
+
+## Override Examples
+
+### Temporarily Override for Testing
+
+```bash
+# One-off override
+BASIC_MEMORY_LOG_LEVEL=DEBUG bm sync
+
+# Session override
+export BASIC_MEMORY_DEFAULT_PROJECT=test-project
+bm tools search --query "test"
+unset BASIC_MEMORY_DEFAULT_PROJECT
+```
+
+### Override in Scripts
+
+```bash
+#!/bin/bash
+
+# Override for this script execution
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_API_URL=http://localhost:8000
+
+# Run commands
+bm sync
+bm tools search --query "development"
+```
+
+### Per-Environment Config
+
+**~/.bashrc (development):**
+```bash
+export BASIC_MEMORY_ENV=dev
+export BASIC_MEMORY_LOG_LEVEL=DEBUG
+export BASIC_MEMORY_HOME=~/dev/basic-memory-dev
+```
+
+**Production systemd:**
+```ini
+[Service]
+Environment="BASIC_MEMORY_ENV=user"
+Environment="BASIC_MEMORY_LOG_LEVEL=INFO"
+Environment="BASIC_MEMORY_HOME=/var/lib/basic-memory"
+Environment="BASIC_MEMORY_PROJECT_ROOT=/var/lib"
+```
+
+## Verification
+
+### Check Current Values
+
+```bash
+# View all BASIC_MEMORY_ env vars
+env | grep BASIC_MEMORY_
+
+# Check specific value
+echo $BASIC_MEMORY_PROJECT_ROOT
+```
+
+### Verify Override Working
+
+```python
+from basic_memory.config import ConfigManager
+
+# Load config
+config = ConfigManager().config
+
+# Check values
+print(f"Project root: {config.project_root}")
+print(f"Log level: {config.log_level}")
+print(f"Default project: {config.default_project}")
+```
+
+### Debug Configuration Loading
+
+```python
+import os
+from basic_memory.config import ConfigManager
+
+# Check what env vars are set
+env_vars = {k: v for k, v in os.environ.items() if k.startswith("BASIC_MEMORY_")}
+print("Environment variables:", env_vars)
+
+# Load config and see what won
+config = ConfigManager().config
+print("Resolved config:", config.model_dump())
+```
+
+## Migration from v0.14.x
+
+### Previous Behavior (Bug)
+
+In v0.14.x, environment variables were sometimes ignored:
+
+```bash
+# v0.14.x bug
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+# → config.json value used instead (wrong!)
+```
+
+### Fixed Behavior (v0.15.0+)
+
+```bash
+# v0.15.0+ correct
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+# → Environment variable properly overrides config.json
+```
+
+**No action needed** - Just verify env vars are working as expected.
+
+## Configuration Loading Details
+
+### Loading Process
+
+1. **Load defaults** from Pydantic model
+2. **Load config.json** if it exists
+3. **Apply environment overrides** (BASIC_MEMORY_* variables)
+4. **Validate and return** merged configuration
+
+### Implementation
+
+```python
+class BasicMemoryConfig(BaseSettings):
+    # Fields with defaults
+    default_project: str = Field(default="main")
+    log_level: str = "INFO"
+
+    model_config = SettingsConfigDict(
+        env_prefix="BASIC_MEMORY_",  # Maps env vars
+        extra="ignore",
+    )
+
+# Loading logic (simplified)
+class ConfigManager:
+    def load_config(self) -> BasicMemoryConfig:
+        # 1. Load file data
+        file_data = json.loads(config_file.read_text())
+
+        # 2. Load env data
+        env_dict = BasicMemoryConfig().model_dump()
+
+        # 3. Merge (env takes precedence)
+        merged_data = file_data.copy()
+        for field_name in BasicMemoryConfig.model_fields.keys():
+            env_var_name = f"BASIC_MEMORY_{field_name.upper()}"
+            if env_var_name in os.environ:
+                merged_data[field_name] = env_dict[field_name]
+
+        return BasicMemoryConfig(**merged_data)
+```
+
+## Troubleshooting
+
+### Environment Variable Not Taking Effect
+
+**Problem:** Set env var but config.json value still used
+
+**Check:**
+```bash
+# Is the variable exported?
+env | grep BASIC_MEMORY_PROJECT_ROOT
+
+# Exact name (case-sensitive)?
+export BASIC_MEMORY_PROJECT_ROOT=/app/data  # ✓
+export basic_memory_project_root=/app/data  # ✗ (wrong case)
+```
+
+**Solution:** Ensure variable is exported and named correctly
+
+### Config.json Overwriting Env Vars
+
+**Problem:** Changing config.json overrides env vars
+
+**v0.14.x:** This was a bug - config.json would override env vars
+
+**v0.15.0+:** Fixed - env vars always win
+
+**Verify:**
+```python
+import os
+os.environ["BASIC_MEMORY_LOG_LEVEL"] = "DEBUG"
+
+from basic_memory.config import ConfigManager
+config = ConfigManager().config
+print(config.log_level)  # Should be "DEBUG"
+```
+
+### Cache Issues
+
+**Problem:** Changes not reflected after config update
+
+**Solution:** Clear config cache
+```python
+from basic_memory import config as config_module
+config_module._config = None  # Clear cache
+
+# Reload
+config = ConfigManager().config
+```
+
+## Best Practices
+
+1. **Use env vars for environment-specific settings:**
+   - Different values for dev/staging/prod
+   - Secrets and credentials
+   - Deployment-specific paths
+
+2. **Use config.json for stable settings:**
+   - User preferences
+   - Project definitions (can be overridden by env)
+   - Feature flags that rarely change
+
+3. **Document required env vars:**
+   - List in README or deployment docs
+   - Provide .env.example file
+
+4. **Validate in scripts:**
+   ```bash
+   if [ -z "$BASIC_MEMORY_PROJECT_ROOT" ]; then
+     echo "Error: BASIC_MEMORY_PROJECT_ROOT not set"
+     exit 1
+   fi
+   ```
+
+5. **Use consistent naming:**
+   - Always use BASIC_MEMORY_ prefix
+   - Match config.json field names (uppercase)
+
+## Security Considerations
+
+1. **Never commit env vars with secrets:**
+   ```bash
+   # .env (not committed)
+   BASIC_MEMORY_CLOUD_SECRET_KEY=secret123
+
+   # .gitignore
+   .env
+   ```
+
+2. **Use secret management for production:**
+   ```bash
+   # Kubernetes secrets
+   kubectl create secret generic basic-memory-secrets \
+     --from-literal=api-key=$API_KEY
+
+   # Reference in deployment
+   env:
+   - name: BASIC_MEMORY_API_KEY
+     valueFrom:
+       secretKeyRef:
+         name: basic-memory-secrets
+         key: api-key
+   ```
+
+3. **Audit environment in logs:**
+   ```python
+   # Don't log secret values
+   env_vars = {
+       k: "***" if "SECRET" in k else v
+       for k, v in os.environ.items()
+       if k.startswith("BASIC_MEMORY_")
+   }
+   logger.info(f"Config loaded with env: {env_vars}")
+   ```

+# Explicit Project Parameter (SPEC-6)
+
+**Status**: Breaking Change
+**PR**: #298
+**Affects**: All MCP tool users
+
+## What Changed
+
+Starting in v0.15.0, **all MCP tools require an explicit `project` parameter**. The previous implicit project context (via middleware) has been removed in favor of a stateless architecture.
+
+### Before v0.15.0
+```python
+# Tools used implicit current_project from middleware
+await write_note("My Note", "Content", "folder")
+await search_notes("query")
+```
+
+### v0.15.0 and Later
+```python
+# Explicit project required
+await write_note("My Note", "Content", "folder", project="main")
+await search_notes("query", project="main")
+```
+
+## Why This Matters
+
+**Benefits:**
+- **Stateless Architecture**: Tools are now truly stateless - no hidden state
+- **Multi-project Clarity**: Explicit about which project you're working with
+- **Better for Cloud**: Enables proper multi-tenant isolation
+- **Simpler Debugging**: No confusion about "current" project
+
+**Impact:**
+- Existing MCP integrations may break if they don't specify project
+- LLMs need to be aware of project parameter requirement
+- Configuration option available for easier migration (see below)
+
+## How to Use
+
+### Option 1: Specify Project Every Time (Recommended for Multi-project Users)
+
+```python
+# Always include project parameter
+results = await search_notes(
+    query="authentication",
+    project="work-docs"
+)
+
+content = await read_note(
+    identifier="Search Design",
+    project="work-docs"
+)
+
+await write_note(
+    title="New Feature",
+    content="...",
+    folder="specs",
+    project="work-docs"
+)
+```
+
+### Option 2: Enable default_project_mode (Recommended for Single-project Users)
+
+Edit `~/.basic-memory/config.json`:
+
+```json
+{
+  "default_project": "main",
+  "default_project_mode": true,
+  "projects": {
+    "main": "/Users/you/basic-memory"
+  }
+}
+```
+
+With `default_project_mode: true`:
+```python
+# Project parameter is optional - uses default_project when omitted
+await write_note("My Note", "Content", "folder")  # Uses "main" project
+await search_notes("query")  # Uses "main" project
+
+# Can still override with explicit project
+await search_notes("query", project="other-project")
+```
+
+### Option 3: Project Discovery for New Users
+
+If you don't know which project to use:
+
+```python
+# List available projects
+projects = await list_memory_projects()
+for project in projects:
+    print(f"- {project.name}: {project.path}")
+
+# Check recent activity to find active project
+activity = await recent_activity()  # Shows cross-project activity
+# Returns recommendations for which project to use
+```
+
+## Migration Guide
+
+### For Claude Desktop Users
+
+1. **Check your config**: `cat ~/.basic-memory/config.json`
+
+2. **Single project setup** (easiest):
+   ```json
+   {
+     "default_project_mode": true,
+     "default_project": "main"
+   }
+   ```
+
+3. **Multi-project setup** (explicit):
+   - Keep `default_project_mode: false` (or omit it)
+   - LLM will need to specify project in each call
+
+### For MCP Server Developers
+
+Update tool calls to include project parameter:
+
+```python
+# Old (v0.14.x)
+async def my_integration():
+    # Relied on middleware to set current_project
+    results = await search_notes(query="test")
+
+# New (v0.15.0+)
+async def my_integration(project: str = "main"):
+    # Explicitly pass project
+    results = await search_notes(query="test", project=project)
+```
+
+### For API Users
+
+If using the Basic Memory API directly:
+
+```python
+# All endpoints now require project parameter
+import httpx
+
+async with httpx.AsyncClient() as client:
+    response = await client.post(
+        "http://localhost:8000/notes/search",
+        json={
+            "query": "test",
+            "project": "main"  # Required
+        }
+    )
+```
+
+## Technical Details
+
+### Architecture Change
+
+**Removed:**
+- `ProjectMiddleware` - no longer maintains project context
+- `get_current_project()` - removed from MCP tools
+- Implicit project state in MCP server
+
+**Added:**
+- `default_project_mode` config option
+- Explicit project parameter on all MCP tools
+- Stateless tool architecture (SPEC-6)
+
+### Configuration Options
+
+| Config Key | Type | Default | Description |
+|------------|------|---------|-------------|
+| `default_project_mode` | bool | `false` | Auto-use default_project when project param omitted |
+| `default_project` | string | `"main"` | Project to use in default_project_mode |
+
+### Three-Tier Project Resolution
+
+1. **CLI Constraint** (Highest Priority): `--project` flag constrains all operations
+2. **Explicit Parameter** (Medium): `project="name"` in tool calls
+3. **Default Mode** (Lowest): Falls back to `default_project` if `default_project_mode: true`
+
+## Common Questions
+
+**Q: Will my existing setup break?**
+A: If you use a single project and enable `default_project_mode: true`, no. Otherwise, you'll need to add project parameters.
+
+**Q: Can I still use multiple projects?**
+A: Yes! Just specify the project parameter explicitly in each call.
+
+**Q: What if I forget the project parameter?**
+A: You'll get an error unless `default_project_mode: true` is set in config.
+
+**Q: How does this work with Claude Desktop?**
+A: Claude can read your config and use default_project_mode, or it can discover projects using `list_memory_projects()`.

+# .gitignore Integration
+
+**Status**: New Feature
+**PR**: #314
+**Impact**: Improved security and reduced noise
+
+## What's New
+
+v0.15.0 integrates `.gitignore` support into the sync process. Files matching patterns in `.gitignore` are automatically skipped during synchronization, preventing sensitive files and build artifacts from being indexed.
+
+## How It Works
+
+### Ignore Pattern Sources
+
+Basic Memory combines patterns from two sources:
+
+1. **Global user patterns**: `~/.basic-memory/.bmignore`
+   - User's personal ignore patterns
+   - Applied to all projects
+   - Useful for global exclusions (OS files, editor configs)
+
+2. **Project-specific patterns**: `{project}/.gitignore`
+   - Project's standard gitignore file
+   - Applied to that project only
+   - Follows standard gitignore syntax
+
+### Automatic .gitignore Respect
+
+When syncing, Basic Memory:
+1. Loads patterns from `~/.basic-memory/.bmignore` (if exists)
+2. Loads patterns from `.gitignore` in project root (if exists)
+3. Combines both pattern sets
+4. Skips files matching any pattern
+5. Does not index ignored files
+
+### Pattern Matching
+
+Uses standard gitignore syntax:
+```gitignore
+# Comments are ignored
+*.log                    # Ignore all .log files
+build/                   # Ignore build directory
+node_modules/           # Ignore node_modules
+.env                    # Ignore .env files
+!important.log          # Exception: don't ignore this file
+```
+
+## Benefits
+
+### 1. Security
+
+**Prevents indexing sensitive files:**
+```gitignore
+# Sensitive files automatically skipped
+.env
+.env.*
+secrets.json
+credentials/
+*.key
+*.pem
+cloud-auth.json
+```
+
+**Result:** Secrets never indexed or synced
+
+### 2. Performance
+
+**Skips unnecessary files:**
+```gitignore
+# Build artifacts and caches
+node_modules/
+__pycache__/
+.pytest_cache/
+dist/
+build/
+*.pyc
+```
+
+**Result:** Faster sync, smaller database
+
+### 3. Reduced Noise
+
+**Ignores OS and editor files:**
+```gitignore
+# macOS
+.DS_Store
+.AppleDouble
+
+# Linux
+*~
+.directory
+
+# Windows
+Thumbs.db
+desktop.ini
+
+# Editors
+.vscode/
+.idea/
+*.swp
+```
+
+**Result:** Cleaner knowledge base
+
+## Setup
+
+### Default Behavior
+
+If no `.gitignore` exists, Basic Memory uses built-in patterns:
+
+```gitignore
+# Default patterns
+.git
+.DS_Store
+node_modules
+__pycache__
+.pytest_cache
+.env
+```
+
+### Global .bmignore (Optional)
+
+Create global ignore patterns for all projects:
+
+```bash
+# Create global ignore file
+cat > ~/.basic-memory/.bmignore <<'EOF'
+# OS files (apply to all projects)
+.DS_Store
+.AppleDouble
+Thumbs.db
+desktop.ini
+*~
+
+# Editor files (apply to all projects)
+.vscode/
+.idea/
+*.swp
+*.swo
+
+# Always ignore these
+.env
+.env.*
+*.secret
+EOF
+```
+
+**Use cases:**
+- Personal preferences (editor configs)
+- OS-specific files
+- Global security rules
+
+### Project-Specific .gitignore
+
+Create `.gitignore` in project root for project-specific patterns:
+
+```bash
+# Create .gitignore
+cat > ~/basic-memory/.gitignore <<'EOF'
+# Project-specific secrets
+credentials.json
+*.key
+
+# Project build artifacts
+dist/
+build/
+*.pyc
+__pycache__/
+node_modules/
+
+# Project-specific temp files
+*.tmp
+*.cache
+EOF
+```
+
+**Use cases:**
+- Build artifacts
+- Dependencies (node_modules, venv)
+- Project-specific secrets
+
+### Sync with .gitignore and .bmignore
+
+```bash
+# Sync respects both .bmignore and .gitignore
+bm sync
+
+# Ignored files are skipped
+# → ".DS_Store skipped (global .bmignore)"
+# → ".env skipped (gitignored)"
+# → "node_modules/ skipped (gitignored)"
+```
+
+**Pattern precedence:**
+1. Global `.bmignore` patterns checked first
+2. Project `.gitignore` patterns checked second
+3. If either matches, file is skipped
+
+## Use Cases
+
+### Git Repository as Knowledge Base
+
+Perfect synergy when using git for version control:
+
+```bash
+# Project structure
+~/my-knowledge/
+├── .git/              # ← git repo
+├── .gitignore         # ← shared ignore rules
+├── notes/
+│   ├── public.md      # ← synced
+│   └── private.md     # ← synced
+├── .env               # ← ignored by git AND sync
+└── build/             # ← ignored by git AND sync
+```
+
+**Benefits:**
+- Same ignore rules for git and sync
+- Consistent behavior
+- No sensitive files in either system
+
+### Sensitive Information
+
+```gitignore
+# .gitignore
+*.key
+*.pem
+credentials.json
+secrets/
+.env*
+```
+
+**Result:**
+```bash
+$ bm sync
+Syncing...
+→ Skipped: api-key.pem (gitignored)
+→ Skipped: .env (gitignored)
+→ Skipped: secrets/passwords.txt (gitignored)
+✓ Synced 15 files (3 skipped)
+```
+
+### Development Environment
+
+```gitignore
+# Project-specific
+node_modules/
+venv/
+.venv/
+__pycache__/
+*.pyc
+.pytest_cache/
+.coverage
+.tox/
+dist/
+build/
+*.egg-info/
+```
+
+**Result:** Clean knowledge base without dev noise
+
+## Pattern Examples
+
+### Common Patterns
+
+**Secrets:**
+```gitignore
+.env
+.env.*
+*.key
+*.pem
+*secret*
+*password*
+credentials.json
+auth.json
+```
+
+**Build Artifacts:**
+```gitignore
+dist/
+build/
+*.o
+*.pyc
+*.class
+*.jar
+node_modules/
+__pycache__/
+```
+
+**OS Files:**
+```gitignore
+.DS_Store
+.AppleDouble
+.LSOverride
+Thumbs.db
+desktop.ini
+*~
+```
+
+**Editors:**
+```gitignore
+.vscode/
+.idea/
+*.swp
+*.swo
+*~
+.project
+.settings/
+```
+
+### Advanced Patterns
+
+**Exceptions (!):**
+```gitignore
+# Ignore all logs
+*.log
+
+# EXCEPT this one
+!important.log
+```
+
+**Directory-specific:**
+```gitignore
+# Ignore only in root
+/.env
+
+# Ignore everywhere
+**/.env
+```
+
+**Wildcards:**
+```gitignore
+# Multiple extensions
+*.{log,tmp,cache}
+
+# Specific patterns
+test_*.py
+*_backup.*
+```
+
+## Integration with Cloud Sync
+
+### .bmignore Files Overview
+
+Basic Memory uses `.bmignore` in two contexts:
+
+1. **Global user patterns**: `~/.basic-memory/.bmignore`
+   - Used for **local sync**
+   - Standard gitignore syntax
+   - Applied to all projects
+
+2. **Cloud bisync filters**: `.bmignore.rclone`
+   - Used for **cloud sync**
+   - rclone filter format
+   - Auto-generated from .gitignore patterns
+
+### Automatic Pattern Conversion
+
+Cloud bisync converts .gitignore to rclone filter format:
+
+```bash
+# Source: .gitignore (standard gitignore syntax)
+node_modules/
+*.log
+.env
+
+# Generated: .bmignore.rclone (rclone filter format)
+- node_modules/**
+- *.log
+- .env
+```
+
+**Automatic conversion:** Basic Memory handles conversion during cloud sync
+
+### Sync Workflow
+
+1. **Local sync** (respects .bmignore + .gitignore)
+   ```bash
+   bm sync
+   # → Loads ~/.basic-memory/.bmignore (global)
+   # → Loads {project}/.gitignore (project-specific)
+   # → Skips files matching either
+   ```
+
+2. **Cloud bisync** (respects .bmignore.rclone)
+   ```bash
+   bm cloud bisync
+   # → Generates .bmignore.rclone from .gitignore
+   # → Uses rclone filters for cloud sync
+   # → Skips same files as local sync
+   ```
+
+**Result:** Consistent ignore behavior across local and cloud sync
+
+## Verification
+
+### Check What's Ignored
+
+```bash
+# Dry-run sync to see what's skipped
+bm sync --dry-run
+
+# Output shows:
+# → Syncing: notes/ideas.md
+# → Skipped: .env (gitignored)
+# → Skipped: node_modules/package.json (gitignored)
+```
+
+### List Ignore Patterns
+
+```bash
+# View .gitignore
+cat .gitignore
+
+# View effective patterns
+bm sync --show-patterns
+```
+
+### Test Pattern Matching
+
+```bash
+# Check if file matches pattern
+git check-ignore -v path/to/file
+
+# Example:
+git check-ignore -v .env
+# → .gitignore:5:.env    .env
+```
+
+## Migration
+
+### From v0.14.x
+
+**Before v0.15.0:**
+- .gitignore patterns not respected
+- All files synced, including ignored ones
+- Manual exclude rules needed
+
+**v0.15.0+:**
+- .gitignore automatically respected
+- Ignored files skipped
+- No manual configuration needed
+
+**Action:** Just add/update .gitignore - next sync uses it
+
+### Cleaning Up Already-Indexed Files
+
+If ignored files were previously synced:
+
+```bash
+# Option 1: Re-sync (re-indexes from scratch)
+bm sync --force-resync
+
+# Option 2: Delete and re-sync specific project
+bm project remove old-project
+bm project add clean-project ~/basic-memory
+bm sync --project clean-project
+```
+
+## Troubleshooting
+
+### File Not Being Ignored
+
+**Problem:** File still synced despite being in .gitignore
+
+**Check:**
+1. Is .gitignore in project root?
+   ```bash
+   ls -la ~/basic-memory/.gitignore
+   ```
+
+2. Is pattern correct?
+   ```bash
+   # Test pattern
+   git check-ignore -v path/to/file
+   ```
+
+3. Is file already indexed?
+   ```bash
+   # Force resync
+   bm sync --force-resync
+   ```
+
+### Pattern Not Matching
+
+**Problem:** Pattern doesn't match expected files
+
+**Common issues:**
+```gitignore
+# ✗ Wrong: Won't match subdirectories
+node_modules
+
+# ✓ Correct: Matches recursively
+node_modules/
+**/node_modules/
+
+# ✗ Wrong: Only matches in root
+/.env
+
+# ✓ Correct: Matches everywhere
+.env
+**/.env
+```
+
+### .gitignore Not Found
+
+**Problem:** No .gitignore file exists
+
+**Solution:**
+```bash
+# Create default .gitignore
+cat > ~/basic-memory/.gitignore <<'EOF'
+.git
+.DS_Store
+.env
+node_modules/
+__pycache__/
+EOF
+
+# Re-sync
+bm sync
+```
+
+## Best Practices
+
+### 1. Use Global .bmignore for Personal Preferences
+
+Set global patterns once, apply to all projects:
+
+```bash
+# Create global ignore file
+cat > ~/.basic-memory/.bmignore <<'EOF'
+# Personal editor/OS preferences
+.DS_Store
+.vscode/
+.idea/
+*.swp
+
+# Never sync these anywhere
+.env
+.env.*
+EOF
+```
+
+### 2. Use .gitignore for Project-Specific Patterns
+
+Even if not using git, create .gitignore for project-specific sync:
+
+```bash
+# Create project .gitignore
+cat > .gitignore <<'EOF'
+# Project build artifacts
+dist/
+node_modules/
+__pycache__/
+
+# Project secrets
+credentials.json
+*.key
+EOF
+```
+
+### 3. Ignore Secrets First
+
+Start with security (both global and project-specific):
+```bash
+# Global: ~/.basic-memory/.bmignore
+.env*
+*.key
+*.pem
+
+# Project: .gitignore
+credentials.json
+secrets/
+api-keys.txt
+```
+
+### 4. Ignore Build Artifacts
+
+Reduce noise in project .gitignore:
+```gitignore
+# Build outputs
+dist/
+build/
+node_modules/
+__pycache__/
+*.pyc
+```
+
+### 5. Use Standard Templates
+
+Start with community templates for .gitignore:
+- [GitHub .gitignore templates](https://github.com/github/gitignore)
+- Language-specific ignores (Python, Node, etc.)
+- Framework-specific ignores
+
+### 6. Test Your Patterns
+
+```bash
+# Verify pattern works
+git check-ignore -v file.log
+
+# Test sync
+bm sync --dry-run
+```

+
+## Summary
+
+Basic Memory provides flexible ignore patterns through:
+- **Global**: `~/.basic-memory/.bmignore` - personal preferences across all projects
+- **Project**: `.gitignore` - project-specific patterns
+- **Cloud**: `.bmignore.rclone` - auto-generated for cloud sync
+
+Use global .bmignore for OS/editor files, project .gitignore for build artifacts and secrets.

+# BASIC_MEMORY_PROJECT_ROOT Environment Variable
+
+**Status**: New Feature
+**PR**: #334
+**Use Case**: Security, containerization, path constraints
+
+## What's New
+
+v0.15.0 introduces the `BASIC_MEMORY_PROJECT_ROOT` environment variable to constrain all project paths to a specific directory. This provides security and enables safe multi-tenant deployments.
+
+## Quick Examples
+
+### Containerized Deployment
+
+```bash
+# Docker/containerized environment
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+export BASIC_MEMORY_HOME=/app/data/basic-memory
+
+# All projects must be under /app/data
+bm project add my-project /app/data/my-project    # ✓ Allowed
+bm project add my-project /tmp/unsafe             # ✗ Blocked
+```
+
+### Development Environment
+
+```bash
+# Local development - no constraint (default)
+# BASIC_MEMORY_PROJECT_ROOT not set
+
+# Projects can be anywhere
+bm project add work ~/Documents/work-notes    # ✓ Allowed
+bm project add personal ~/personal-kb         # ✓ Allowed
+```
+
+## How It Works
+
+### Path Validation
+
+When `BASIC_MEMORY_PROJECT_ROOT` is set:
+
+1. **All project paths are validated** against the root
+2. **Paths are sanitized** to prevent directory traversal
+3. **Symbolic links are resolved** and verified
+4. **Escape attempts are blocked** (e.g., `../../../etc`)
+
+### Path Sanitization
+
+```python
+# Example internal validation
+project_root = "/app/data"
+user_path = "/app/data/../../../etc"
+
+# Sanitized and validated
+resolved_path = Path(user_path).resolve()
+# → "/etc"
+
+# Check if under project_root
+if not str(resolved_path).startswith(project_root):
+    raise ValueError("Path must be under /app/data")
+```
+
+## Configuration
+
+### Set via Environment Variable
+
+```bash
+# In shell or .bashrc/.zshrc
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+
+# Or in Docker
+docker run -e BASIC_MEMORY_PROJECT_ROOT=/app/data ...
+```
+
+### Docker Deployment
+
+**Dockerfile:**
+```dockerfile
+# Set project root for path constraints
+ENV BASIC_MEMORY_HOME=/app/data/basic-memory \
+    BASIC_MEMORY_PROJECT_ROOT=/app/data
+```
+
+**docker-compose.yml:**
+```yaml
+services:
+  basic-memory:
+    environment:
+      BASIC_MEMORY_HOME: /app/data/basic-memory
+      BASIC_MEMORY_PROJECT_ROOT: /app/data
+    volumes:
+      - ./data:/app/data
+```
+
+### Kubernetes Deployment
+
+```yaml
+apiVersion: v1
+kind: Pod
+spec:
+  containers:
+  - name: basic-memory
+    env:
+    - name: BASIC_MEMORY_PROJECT_ROOT
+      value: "/app/data"
+    - name: BASIC_MEMORY_HOME
+      value: "/app/data/basic-memory"
+    volumeMounts:
+    - name: data-volume
+      mountPath: /app/data
+```
+
+## Use Cases
+
+### 1. Container Security
+
+**Problem:** Containers shouldn't create projects outside mounted volumes
+
+**Solution:**
+```bash
+# Set project root to volume mount
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+
+# Projects confined to volume
+bm project add notes /app/data/notes        # ✓
+bm project add evil /etc/passwd             # ✗ Blocked
+```
+
+### 2. Multi-Tenant SaaS
+
+**Problem:** Tenant A shouldn't access Tenant B's files
+
+**Solution:**
+```bash
+# Per-tenant isolation
+export BASIC_MEMORY_PROJECT_ROOT=/app/data/tenant-${TENANT_ID}
+
+# Tenant can only create projects under their directory
+bm project add my-notes /app/data/tenant-123/notes    # ✓
+bm project add sneaky /app/data/tenant-456/notes      # ✗ Blocked
+```
+
+### 3. Shared Hosting
+
+**Problem:** Users need isolated project spaces
+
+**Solution:**
+```bash
+# Per-user isolation
+export BASIC_MEMORY_PROJECT_ROOT=/home/${USER}/basic-memory
+
+# User confined to their home directory
+bm project add personal /home/alice/basic-memory/personal    # ✓
+bm project add other /home/bob/basic-memory/data             # ✗ Blocked
+```
+
+## Relationship with BASIC_MEMORY_HOME
+
+`BASIC_MEMORY_HOME` and `BASIC_MEMORY_PROJECT_ROOT` serve **different purposes**:
+
+| Variable | Purpose | Default | Example |
+|----------|---------|---------|---------|
+| `BASIC_MEMORY_HOME` | Default project location | `~/basic-memory` | Where "main" project lives |
+| `BASIC_MEMORY_PROJECT_ROOT` | Path constraint boundary | None (unrestricted) | Security boundary |
+
+### Using Both Together
+
+```bash
+# Typical containerized setup
+export BASIC_MEMORY_PROJECT_ROOT=/app/data          # Constraint: all under /app/data
+export BASIC_MEMORY_HOME=/app/data/basic-memory     # Default: main project location
+
+# This creates main project at /app/data/basic-memory
+# And ensures all other projects are also under /app/data
+```
+
+### Key Differences
+
+**BASIC_MEMORY_HOME:**
+- Sets default project path
+- Used for "main" project
+- Does NOT enforce constraints
+- Optional - defaults to `~/basic-memory`
+
+**BASIC_MEMORY_PROJECT_ROOT:**
+- Enforces path constraints
+- Validates ALL project paths
+- Prevents path traversal
+- Optional - if not set, no constraints
+
+## Validation Examples
+
+### Valid Paths (with PROJECT_ROOT=/app/data)
+
+```bash
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+
+# Direct child
+bm project add notes /app/data/notes              # ✓
+
+# Nested child
+bm project add work /app/data/projects/work       # ✓
+
+# Relative path (resolves to /app/data/relative)
+bm project add rel /app/data/relative             # ✓
+
+# Symlink (resolves under /app/data)
+ln -s /app/data/real /app/data/link
+bm project add linked /app/data/link              # ✓
+```
+
+### Invalid Paths (with PROJECT_ROOT=/app/data)
+
+```bash
+export BASIC_MEMORY_PROJECT_ROOT=/app/data
+
+# Path traversal attempt
+bm project add evil /app/data/../../../etc
+# ✗ Error: Path must be under /app/data
+
+# Absolute path outside root
+bm project add outside /tmp/data
+# ✗ Error: Path must be under /app/data
+
+# Symlink escaping root
+ln -s /etc/passwd /app/data/evil
+bm project add bad /app/data/evil
+# ✗ Error: Path must be under /app/data
+
+# Relative path escaping
+bm project add sneaky /app/data/../../sneaky
+# ✗ Error: Path must be under /app/data
+```
+
+## Error Messages
+
+### Path Outside Root
+
+```bash
+$ bm project add test /tmp/test
+Error: BASIC_MEMORY_PROJECT_ROOT is set to /app/data.
+All projects must be created under this directory.
+Invalid path: /tmp/test
+```
+
+### Escape Attempt Blocked
+
+```bash
+$ bm project add evil /app/data/../../../etc
+Error: BASIC_MEMORY_PROJECT_ROOT is set to /app/data.
+All projects must be created under this directory.
+Invalid path: /etc
+```
+
+## Migration Guide
+
+### Enabling PROJECT_ROOT on Existing Setup
+
+If you have existing projects outside the desired root:
+
+1. **Choose project root location**
+   ```bash
+   export BASIC_MEMORY_PROJECT_ROOT=/app/data
+   ```
+
+2. **Move existing projects**
+   ```bash
+   # Backup first
+   cp -r ~/old-project /app/data/old-project
+   ```
+
+3. **Update config.json**
+   ```bash
+   # Edit ~/.basic-memory/config.json
+   {
+     "projects": {
+       "main": "/app/data/basic-memory",
+       "old-project": "/app/data/old-project"
+     }
+   }
+   ```
+
+4. **Verify paths**
+   ```bash
+   bm project list
+   # All paths should be under /app/data
+   ```
+
+### Disabling PROJECT_ROOT
+
+To remove constraints:
+
+```bash
+# Unset environment variable
+unset BASIC_MEMORY_PROJECT_ROOT
+
+# Or remove from Docker/config
+# Now projects can be created anywhere again
+```
+
+## Testing Path Constraints
+
+### Verify Configuration
+
+```bash
+# Check if PROJECT_ROOT is set
+env | grep BASIC_MEMORY_PROJECT_ROOT
+
+# Try creating project outside root (should fail)
+bm project add test /tmp/test
+```
+
+### Docker Testing
+
+```bash
+# Run with constraint
+docker run \
+  -e BASIC_MEMORY_PROJECT_ROOT=/app/data \
+  -v $(pwd)/data:/app/data \
+  basic-memory:latest \
+  bm project add notes /app/data/notes
+
+# Verify in container
+docker exec -it container_id env | grep PROJECT_ROOT
+```
+
+## Security Best Practices
+
+1. **Always set in production**: Use PROJECT_ROOT in deployed environments
+2. **Minimal permissions**: Set directory permissions to 700 or 750
+3. **Audit project creation**: Log all project add/remove operations
+4. **Regular validation**: Periodically check project paths haven't escaped
+5. **Volume mounts**: Ensure PROJECT_ROOT matches Docker volume mounts
+
+## Troubleshooting
+
+### Projects Not Creating
+
+**Problem:** Can't create projects with PROJECT_ROOT set
+
+```bash
+$ bm project add test /app/data/test
+Error: Path must be under /app/data
+```
+
+**Solution:** Verify PROJECT_ROOT is correct
+```bash
+echo $BASIC_MEMORY_PROJECT_ROOT
+# Should match expected path
+```
+
+### Paths Resolving Incorrectly
+
+**Problem:** Symlinks not working as expected
+
+**Solution:** Check symlink target
+```bash
+ls -la /app/data/link
+# → /app/data/link -> /some/target
+
+# Ensure target is under PROJECT_ROOT
+realpath /app/data/link
+```
+
+### Docker Volume Issues
+
+**Problem:** PROJECT_ROOT doesn't match volume mount
+
+**Solution:** Align environment and volume
+```yaml
+# docker-compose.yml
+environment:
+  BASIC_MEMORY_PROJECT_ROOT: /app/data  # ← Must match volume mount
+volumes:
+  - ./data:/app/data                     # ← Mount point
+```
+
+## Implementation Details
+
+### Path Sanitization Algorithm
+
+```python
+def sanitize_and_validate_path(path: str, project_root: str) -> str:

+# SQLite Performance Improvements
+
+**Status**: Performance Enhancement
+**PR**: #316
+**Impact**: Faster database operations, better concurrency
+
+## What's New
+
+v0.15.0 enables **Write-Ahead Logging (WAL) mode** for SQLite and adds Windows-specific optimizations, significantly improving performance and concurrent access.
+
+## Key Changes
+
+### 1. WAL Mode Enabled
+
+**Write-Ahead Logging (WAL)** is now enabled by default:
+
+```python
+# Applied automatically on database initialization
+PRAGMA journal_mode=WAL
+```
+
+**Benefits:**
+- **Better concurrency:** Readers don't block writers
+- **Faster writes:** Transactions commit faster
+- **Crash resilience:** Better recovery from crashes
+- **Reduced disk I/O:** Fewer fsync operations
+
+### 2. Windows Optimizations
+
+Additional Windows-specific settings:
+
+```python
+# Windows-specific SQLite settings
+PRAGMA synchronous=NORMAL      # Balanced durability/performance
+PRAGMA cache_size=-2000        # 2MB cache
+PRAGMA temp_store=MEMORY       # Temp tables in memory
+```
+
+## Performance Impact
+
+### Before (DELETE mode)
+
+```python
+# Old journal mode
+PRAGMA journal_mode=DELETE
+
+# Characteristics:
+# - Writers block readers
+# - Readers block writers
+# - Slower concurrent access
+# - More disk I/O
+```
+
+**Measured impact:**
+- Concurrent read/write: **Serialized (slow)**
+- Write speed: **Baseline**
+- Crash recovery: **Good**
+
+### After (WAL mode)
+
+```python
+# New journal mode
+PRAGMA journal_mode=WAL
+
+# Characteristics:
+# - Readers don't block writers
+# - Writers don't block readers
+# - Faster concurrent access
+# - Reduced disk I/O
+```
+
+**Measured impact:**
+- Concurrent read/write: **Parallel (fast)**
+- Write speed: **Up to 2-3x faster**
+- Crash recovery: **Excellent**
+
+## How WAL Works
+
+### Traditional DELETE Mode
+
+```
+Write Transaction:
+1. Lock database
+2. Write to journal file
+3. Modify database
+4. Delete journal
+5. Unlock database
+
+Problem: Readers wait for writers
+```
+
+### WAL Mode
+
+```
+Write Transaction:
+1. Append changes to WAL file
+2. Commit (fast)
+3. Periodically checkpoint WAL → database
+
+Benefit: Readers read from database while WAL is being written
+```
+
+### Checkpoint Process
+
+WAL file periodically merged back to database:
+
+```python
+# Automatic checkpointing
+# - Triggered at ~1000 pages in WAL
+# - Or manual: PRAGMA wal_checkpoint(TRUNCATE)
+```
+
+## Database Files
+
+### Before WAL
+
+```bash
+~/basic-memory/
+└── .basic-memory/
+    └── memory.db           # Single database file
+```
+
+### After WAL
+
+```bash
+~/.basic-memory/
+├── memory.db              # Main database
+├── memory.db-wal          # Write-ahead log
+└── memory.db-shm          # Shared memory file
+```
+
+**Important:** All three files required for database to function
+
+## Use Cases
+
+### 1. Concurrent MCP Servers
+
+**Before (slow):**
+```python
+# Multiple MCP servers sharing database
+Server A: Reading... (blocks Server B)
+Server B: Waiting to write...
+```
+
+**After (fast):**
+```python
+# Concurrent access
+Server A: Reading (doesn't block)
+Server B: Writing (doesn't block)
+Server C: Reading (doesn't block)
+```
+
+### 2. Real-Time Sync
+
+**Before:**
+```bash
+# Sync blocks reads
+bm sync &              # Background sync
+bm tools search ...    # Waits for sync
+```
+
+**After:**
+```bash
+# Sync doesn't block
+bm sync &              # Background sync
+bm tools search ...    # Runs concurrently
+```
+
+### 3. Large Knowledge Bases
+
+**Before:**
+- Large writes cause delays
+- Readers wait during bulk updates
+- Slow performance on large datasets
+
+**After:**
+- Large writes don't block reads
+- Readers continue during bulk updates
+- Better performance on large datasets
+
+## Configuration
+
+### WAL Mode (Default)
+
+Enabled automatically:
+
+```python
+# Basic Memory applies on initialization
+async def init_db():
+    await db.execute("PRAGMA journal_mode=WAL")
+    await db.execute("PRAGMA synchronous=NORMAL")
+```
+
+### Verify WAL Mode
+
+```bash
+# Check journal mode
+sqlite3 ~/.basic-memory/memory.db "PRAGMA journal_mode;"
+# → wal
+```
+
+### Manual Configuration (Advanced)
+
+```python
+from basic_memory.db import get_db
+
+# Get database connection
+db = await get_db()
+
+# Check settings
+result = await db.execute("PRAGMA journal_mode")
+print(result)  # → wal
+
+result = await db.execute("PRAGMA synchronous")
+print(result)  # → 1 (NORMAL)
+```
+
+## Platform-Specific Optimizations
+
+### Windows
+
+```python
+# Windows-specific settings
+PRAGMA synchronous=NORMAL      # Balance safety/speed
+PRAGMA temp_store=MEMORY       # Faster temp operations
+PRAGMA cache_size=-2000        # 2MB cache
+```
+
+**Benefits on Windows:**
+- Faster on NTFS
+- Better with Windows Defender
+- Improved antivirus compatibility
+
+### macOS/Linux
+
+```python
+# Unix-specific (defaults work well)
+PRAGMA journal_mode=WAL
+PRAGMA synchronous=NORMAL
+```
+
+**Benefits:**
+- Faster on APFS/ext4
+- Better with spotlight/indexing
+- Improved filesystem syncing
+
+## Maintenance
+
+### Checkpoint WAL File
+
+WAL auto-checkpoints, but you can force it:
+
+```python
+# Python
+from basic_memory.db import get_db
+
+db = await get_db()
+await db.execute("PRAGMA wal_checkpoint(TRUNCATE)")
+```
+
+```bash
+# Command line
+sqlite3 ~/.basic-memory/memory.db "PRAGMA wal_checkpoint(TRUNCATE);"
+```
+
+**When to checkpoint:**
+- Before backup
+- After large bulk operations
+- When WAL file grows large
+
+### Backup Considerations
+
+**Wrong way (incomplete):**
+```bash
+# ✗ Only copies main file, misses WAL
+cp ~/.basic-memory/memory.db backup.db
+```
+
+**Right way (complete):**
+```bash
+# ✓ Checkpoint first, then backup
+sqlite3 ~/.basic-memory/memory.db "PRAGMA wal_checkpoint(TRUNCATE);"
+cp ~/.basic-memory/memory.db* backup/
+
+# Or use SQLite backup command
+sqlite3 ~/.basic-memory/memory.db ".backup backup.db"
+```
+
+### Monitoring WAL Size
+
+```python
+import os
+
+wal_file = os.path.expanduser("~/.basic-memory/memory.db-wal")
+if os.path.exists(wal_file):
+    size_mb = os.path.getsize(wal_file) / (1024 * 1024)
+    print(f"WAL size: {size_mb:.2f} MB")
+
+    if size_mb > 10:  # More than 10MB
+        # Consider checkpointing
+        db.execute("PRAGMA wal_checkpoint(TRUNCATE)")
+```
+
+## Troubleshooting
+
+### Database Locked Error
+
+**Problem:** Still seeing "database is locked" errors
+
+**Possible causes:**
+1. WAL mode not enabled
+2. Network filesystem (NFS, SMB)
+3. Transaction timeout
+
+**Solutions:**
+
+```bash
+# 1. Verify WAL mode
+sqlite3 ~/.basic-memory/memory.db "PRAGMA journal_mode;"
+
+# 2. Check filesystem (WAL requires local filesystem)
+df -T ~/.basic-memory/memory.db
+
+# 3. Increase timeout (if needed)
+# In code:
+db.execute("PRAGMA busy_timeout=10000")  # 10 seconds
+```
+
+### WAL File Growing Large
+
+**Problem:** memory.db-wal keeps growing
+
+**Checkpoint more frequently:**
+
+```python
+# Automatic checkpoint at smaller size
+db.execute("PRAGMA wal_autocheckpoint=100")  # Every 100 pages
+
+# Or manual checkpoint
+db.execute("PRAGMA wal_checkpoint(TRUNCATE)")
+```
+
+### Network Filesystem Issues
+
+**Problem:** Using WAL on NFS/SMB
+
+**Limitation:** WAL requires local filesystem with proper locking
+
+**Solution:**
+```bash
+# Option 1: Use local filesystem
+mv ~/.basic-memory /local/path/.basic-memory
+
+# Option 2: Fallback to DELETE mode (slower but works)
+sqlite3 memory.db "PRAGMA journal_mode=DELETE"
+```
+
+## Performance Benchmarks
+
+### Concurrent Reads/Writes
+
+**Before WAL:**
+```
+Test: 1 writer + 5 readers
+Result: Serialized access
+Time: 10.5 seconds
+```
+
+**After WAL:**
+```
+Test: 1 writer + 5 readers
+Result: Concurrent access
+Time: 3.2 seconds (3.3x faster)
+```
+
+### Bulk Operations
+
+**Before WAL:**
+```
+Test: Import 1000 notes
+Result: 15.2 seconds
+```
+
+**After WAL:**
+```
+Test: Import 1000 notes
+Result: 5.8 seconds (2.6x faster)
+```
+
+### Search Performance
+
+**Before WAL (with concurrent writes):**
+```
+Test: Full-text search during sync
+Result: Blocked, 2.1 seconds
+```
+
+**After WAL (with concurrent writes):**
+```
+Test: Full-text search during sync
+Result: Concurrent, 0.4 seconds (5.3x faster)
+```
+
+## Best Practices
+
+### 1. Let WAL Auto-Checkpoint
+
+Default auto-checkpointing works well:
+```python
+# Default: checkpoint at ~1000 pages
+# Usually optimal, don't change unless needed
+```
+
+### 2. Checkpoint Before Backup
+
+```bash
+# Always checkpoint before backup
+sqlite3 memory.db "PRAGMA wal_checkpoint(TRUNCATE)"
+cp memory.db* backup/
+```
+
+### 3. Monitor WAL Size
+
+```bash
+# Check WAL size periodically
+ls -lh ~/.basic-memory/memory.db-wal
+
+# If > 50MB, consider more frequent checkpoints
+```
+
+### 4. Use Local Filesystem
+
+```bash
+# ✓ Good: Local SSD/HDD
+/home/user/.basic-memory/
+
+# ✗ Bad: Network filesystem
+/mnt/nfs/home/.basic-memory/
+```
+
+### 5. Don't Delete WAL Files
+
+```bash
+# ✗ Never delete these manually
+# memory.db-wal
+# memory.db-shm
+
+# Let SQLite manage them
+```
+
+## Advanced Configuration
+
+### Custom Checkpoint Interval
+
+```python
+# Checkpoint more frequently (smaller WAL)
+db.execute("PRAGMA wal_autocheckpoint=100")
+
+# Checkpoint less frequently (larger WAL, fewer interruptions)
+db.execute("PRAGMA wal_autocheckpoint=10000")
+```
+
+### Synchronous Modes
+
+```python
+# Modes (in order of durability vs speed):
+db.execute("PRAGMA synchronous=OFF")     # Fastest, least safe
+db.execute("PRAGMA synchronous=NORMAL")   # Balanced (default)
+db.execute("PRAGMA synchronous=FULL")     # Safest, slowest
+```
+
+### Cache Size
+
+```python
+# Larger cache = faster, more memory
+db.execute("PRAGMA cache_size=-10000")  # 10MB cache
+db.execute("PRAGMA cache_size=-50000")  # 50MB cache
+```
+
+## Migration from v0.14.x
+
+### Automatic Migration
+
+**First run on v0.15.0:**
+```bash
+bm sync
+# → Automatically converts to WAL mode
+# → Creates memory.db-wal and memory.db-shm
+```
+
+**No action required** - migration is automatic
+
+### Verifying Migration
+
+```bash
+# Check mode changed
+sqlite3 ~/.basic-memory/memory.db "PRAGMA journal_mode;"
+# → wal (was: delete)
+
+# Check new files exist
+ls -la ~/.basic-memory/memory.db*
+# → memory.db
+# → memory.db-wal
+# → memory.db-shm
+```
