# SPEC-13: CLI Authentication with Subscription Validation
## Why
The Basic Memory Cloud CLI currently has a security gap in authentication that allows unauthorized access:
**Current Web Flow (Secure)**:
1. User signs up via WorkOS AuthKit
2. User creates Polar subscription
3. Web app validates subscription before calling `POST /tenants/setup`
4. Tenant provisioned only after subscription validation ✅
**Current CLI Flow (Insecure)**:
1. User signs up via WorkOS AuthKit (OAuth device flow)
2. User runs `bm cloud login`
3. CLI receives JWT token from WorkOS
4. CLI can access all cloud endpoints without subscription check ❌
**Problem**: Anyone can sign up with WorkOS and immediately access cloud infrastructure via CLI without having an active Polar subscription. This creates:
- Revenue loss (free resource consumption)
- Security risk (unauthorized data access)
- Support burden (users accessing features they haven't paid for)
**Root Cause**: The CLI authentication flow validates JWT tokens but doesn't verify subscription status before granting access to cloud resources.
## What
Add subscription validation to authentication flow to ensure only users with active Polar subscriptions can access cloud resources across all access methods (CLI, MCP, Web App, Direct API).
**Affected Components**:
### basic-memory-cloud (Cloud Service)
- `apps/cloud/src/basic_memory_cloud/deps.py` - Add subscription validation dependency
- `apps/cloud/src/basic_memory_cloud/services/subscription_service.py` - Add subscription check method
- `apps/cloud/src/basic_memory_cloud/api/tenant_mount.py` - Protect mount endpoints
- `apps/cloud/src/basic_memory_cloud/api/proxy.py` - Protect proxy endpoints
### basic-memory (CLI)
- `src/basic_memory/cli/commands/cloud/core_commands.py` - Handle 403 errors
- `src/basic_memory/cli/commands/cloud/api_client.py` - Parse subscription errors
- `docs/cloud-cli.md` - Document subscription requirement
**Endpoints to Protect**:
- `GET /tenant/mount/info` - Used by CLI bisync setup
- `POST /tenant/mount/credentials` - Used by CLI bisync credentials
- `GET /proxy/{path:path}` - Used by Web App, MCP tools, CLI tools, Direct API
- All other `/proxy/*` endpoints - Centralized access point for all user operations
## Complete Authentication Flow Analysis
### Overview of All Access Flows
Basic Memory Cloud has **7 distinct authentication flows**. This spec closes subscription validation gaps in flows 2-4 and 6, which all converge on the `/proxy/*` endpoints.
### Flow 1: Polar Webhook → Registration ✅ SECURE
```
Polar webhook → POST /api/webhooks/polar
→ Validates Polar webhook signature
→ Creates/updates subscription in database
→ No direct user access - webhook only
```
**Auth**: Polar webhook signature validation
**Subscription Check**: N/A (webhook creates subscriptions)
**Status**: ✅ Secure - webhook validated, no user JWT involved
### Flow 2: Web App Login ❌ NEEDS FIX
```
User → apps/web (Vue.js/Nuxt)
→ WorkOS AuthKit magic link authentication
→ JWT stored in browser session
→ Web app calls /proxy/{project}/... endpoints (memory, directory, projects)
→ proxy.py validates JWT but does NOT check subscription
→ Access granted without subscription ❌
```
**Auth**: WorkOS JWT via `CurrentUserProfileHybridJwtDep`
**Subscription Check**: ❌ Missing
**Fixed By**: Task 1.4 (protect `/proxy/*` endpoints)
### Flow 3: MCP (Model Context Protocol) ❌ NEEDS FIX
```
AI Agent (Claude, Cursor, etc.) → https://mcp.basicmemory.com
→ AuthKit OAuth device flow
→ JWT stored in AI agent
→ MCP tools call {cloud_host}/proxy/{endpoint} with Authorization header
→ proxy.py validates JWT but does NOT check subscription
→ MCP tools can access all cloud resources without subscription ❌
```
**Auth**: AuthKit JWT via `CurrentUserProfileHybridJwtDep`
**Subscription Check**: ❌ Missing
**Fixed By**: Task 1.4 (protect `/proxy/*` endpoints)
### Flow 4: CLI Auth (basic-memory) ❌ NEEDS FIX
```
User → bm cloud login
→ AuthKit OAuth device flow
→ JWT stored in ~/.basic-memory/tokens.json
→ CLI calls:
- {cloud_host}/tenant/mount/info (for bisync setup)
- {cloud_host}/tenant/mount/credentials (for bisync credentials)
- {cloud_host}/proxy/{endpoint} (for all MCP tools)
→ tenant_mount.py and proxy.py validate JWT but do NOT check subscription
→ Access granted without subscription ❌
```
**Auth**: AuthKit JWT via `CurrentUserProfileHybridJwtDep`
**Subscription Check**: ❌ Missing
**Fixed By**: Task 1.3 (protect `/tenant/mount/*`) + Task 1.4 (protect `/proxy/*`)
### Flow 5: Cloud CLI (Admin Tasks) ✅ SECURE
```
Admin → python -m basic_memory_cloud.cli.tenant_cli
→ Uses CLIAuth with admin WorkOS OAuth client
→ Gets JWT token with admin org membership
→ Calls /tenants/* endpoints (create, list, delete tenants)
→ tenants.py validates JWT AND admin org membership via AdminUserHybridDep
→ Access granted only to admin organization members ✅
```
**Auth**: AuthKit JWT + Admin org validation via `AdminUserHybridDep`
**Subscription Check**: N/A (admins bypass subscription requirement)
**Status**: ✅ Secure - admin-only endpoints, separate from user flows
### Flow 6: Direct API Calls ❌ NEEDS FIX
```
Any HTTP client → {cloud_host}/proxy/{endpoint}
→ Sends Authorization: Bearer {jwt} header
→ proxy.py validates JWT but does NOT check subscription
→ Direct API access without subscription ❌
```
**Auth**: WorkOS or AuthKit JWT via `CurrentUserProfileHybridJwtDep`
**Subscription Check**: ❌ Missing
**Fixed By**: Task 1.4 (protect `/proxy/*` endpoints)
### Flow 7: Tenant API Instance (Internal) ✅ SECURE
```
/proxy/* → Tenant API (basic-memory-{tenant_id}.fly.dev)
→ Validates signed header from proxy (tenant_id + signature)
→ Direct external access will be disabled in production
→ Only accessible via /proxy endpoints
```
**Auth**: Signed header validation from proxy
**Subscription Check**: N/A (internal only, validated at proxy layer)
**Status**: ✅ Secure - validates proxy signature, not directly accessible
### Authentication Flow Summary Matrix
| Flow | Access Method | Current Auth | Subscription Check | Fixed By SPEC-13 |
|------|---------------|--------------|-------------------|------------------|
| 1. Polar Webhook | Polar webhook → `/api/webhooks/polar` | Polar signature | N/A (webhook) | N/A |
| 2. Web App | Browser → `/proxy/*` | WorkOS JWT ✅ | ❌ Missing | ✅ Task 1.4 |
| 3. MCP | AI Agent → `/proxy/*` | AuthKit JWT ✅ | ❌ Missing | ✅ Task 1.4 |
| 4. CLI | `bm cloud` → `/tenant/mount/*` + `/proxy/*` | AuthKit JWT ✅ | ❌ Missing | ✅ Task 1.3 + 1.4 |
| 5. Cloud CLI (Admin) | `tenant_cli` → `/tenants/*` | AuthKit JWT ✅ + Admin org | N/A (admin) | N/A (admin bypass) |
| 6. Direct API | HTTP client → `/proxy/*` | WorkOS/AuthKit JWT ✅ | ❌ Missing | ✅ Task 1.4 |
| 7. Tenant API | Proxy → tenant instance | Proxy signature ✅ | N/A (internal) | N/A |
### Key Insights
1. **Single Point of Failure**: All user access (Web, MCP, CLI, Direct API) converges on `/proxy/*` endpoints
2. **Centralized Fix**: Protecting `/proxy/*` with subscription validation closes gaps in flows 2, 3, 4, and 6 simultaneously
3. **Admin Bypass**: Cloud CLI admin tasks use separate `/tenants/*` endpoints with admin-only access (no subscription needed)
4. **Defense in Depth**: `/tenant/mount/*` endpoints also protected for CLI bisync operations
### Architecture Benefits
The `/proxy` layer serves as the **single centralized authorization point** for all user access:
- ✅ One place to validate JWT tokens
- ✅ One place to check subscription status
- ✅ One place to handle tenant routing
- ✅ Protects Web App, MCP, CLI, and Direct API simultaneously
This architecture makes the fix comprehensive and maintainable.
## How (High Level)
### Option A: Database Subscription Check (Recommended)
**Approach**: Add FastAPI dependency that validates subscription status from database before allowing access.
**Implementation**:
1. **Create Subscription Validation Dependency** (`deps.py`)

"message": "Active subscription required for CLI access",
"subscribe_url": "https://basicmemory.com/subscribe"
}
)
# Look up and return user profile
user_profile = await user_profile_repo.get_user_profile_by_workos_user_id(
session, user_context.workos_user_id
)
if not user_profile:
raise HTTPException(401, detail="User profile not found")
return user_profile
```
```python
AuthorizedCLIUserProfileDep = Annotated[UserProfile, Depends(get_authorized_cli_user_profile)]
```
2. **Add Subscription Check Method** (`subscription_service.py`)
```python
async def check_user_has_active_subscription(
self, session: AsyncSession, workos_user_id: str
) -> bool:
"""Check if user has active subscription."""
# Use existing repository method to get subscription by workos_user_id
# This joins UserProfile -> Subscription in a single query
subscription = await self.subscription_repository.get_subscription_by_workos_user_id(
session, workos_user_id
)
return subscription is not None and subscription.status == "active"
```
3. **Protect Endpoints** (Replace `CurrentUserProfileHybridJwtDep` with `AuthorizedCLIUserProfileDep`)
```python
# Before
@router.get("/mount/info")
async def get_mount_info(
user_profile: CurrentUserProfileHybridJwtDep,
session: DatabaseSessionDep,
):
tenant_id = user_profile.tenant_id
...
# After
@router.get("/mount/info")
async def get_mount_info(
user_profile: AuthorizedCLIUserProfileDep, # Now includes subscription check
session: DatabaseSessionDep,
):
tenant_id = user_profile.tenant_id # No changes needed to endpoint logic
...
```
4. **Update CLI Error Handling**
```python
# In core_commands.py login()
try:
success = await auth.login()
if success:
# Test subscription by calling protected endpoint
await make_api_request("GET", f"{host_url}/tenant/mount/info")
except CloudAPIError as e:
if e.status_code == 403 and e.detail.get("error") == "subscription_required":
console.print("[red]Subscription required[/red]")
console.print(f"Subscribe at: {e.detail['subscribe_url']}")
raise typer.Exit(1)
```
**Pros**:
- Simple to implement
- Fast (single database query)
- Clear error messages
- Works with existing subscription flow
**Cons**:
- Database is source of truth (could get out of sync with Polar)
- Adds one extra subscription lookup query per request (lightweight JOIN query)
### Option B: WorkOS Organizations
**Approach**: Add users to "beta-users" organization in WorkOS after subscription creation, validate org membership via JWT claims.
**Implementation**:
1. After Polar subscription webhook, add user to WorkOS org via API
2. Validate `org_id` claim in JWT matches authorized org
3. Use existing `get_admin_workos_jwt` pattern
**Pros**:
- WorkOS as single source of truth
- No database queries needed
- More secure (harder to bypass)
**Cons**:
- More complex (requires WorkOS API integration)
- Requires managing WorkOS org membership
- Less control over error messages
- Additional API calls during registration
### Recommendation
**Start with Option A (Database Check)** for:
- Faster implementation
- Clearer error messages
- Easier testing
- Existing subscription infrastructure
**Consider Option B later** if:
- Need tighter security
- Want to reduce database dependency
- Scale requires fewer database queries

```
## Implementation Tasks
### Phase 1: Cloud Service (basic-memory-cloud)
#### Task 1.1: Add subscription check method to SubscriptionService ✅
**File**: `apps/cloud/src/basic_memory_cloud/services/subscription_service.py`
- [x] Add method `check_subscription(session: AsyncSession, workos_user_id: str) -> bool`
- [x] Use existing `self.subscription_repository.get_subscription_by_workos_user_id(session, workos_user_id)`
- [x] Check both `status == "active"` AND `current_period_end >= now()`

- [x] Add docstring explaining the method
- [x] Run `just typecheck` to verify types
**Actual implementation**:
```python
async def check_subscription(
self, session: AsyncSession, workos_user_id: str
) -> bool:
"""Check if user has active subscription with valid period."""
subscription = await self.subscription_repository.get_subscription_by_workos_user_id(
session, workos_user_id
)
if subscription is None:
return False
if subscription.status != "active":
logger.warning("Subscription inactive", workos_user_id=workos_user_id,
status=subscription.status, current_period_end=subscription.current_period_end)
return False
now = datetime.now(timezone.utc)
if subscription.current_period_end is None or subscription.current_period_end < now:
logger.warning("Subscription expired", workos_user_id=workos_user_id,
status=subscription.status, current_period_end=subscription.current_period_end)
return False
return True
```
#### Task 1.2: Add subscription validation dependency ✅

- [x] Add subscription check using `subscription_service.check_subscription()`
- [x] Raise `HTTPException(403)` with structured error detail if no active subscription
- [x] Look up and return `UserProfile` after validation
- [x] Add `AuthorizedUserProfileDep` type annotation
- [x] Use `settings.subscription_url` from config (env var)
- [x] Run `just typecheck` to verify types
**Expected code**:
```python
async def get_authorized_cli_user_profile(
credentials: Annotated[HTTPAuthorizationCredentials, Depends(security)],
session: DatabaseSessionDep,
user_profile_repo: UserProfileRepositoryDep,
subscription_service: SubscriptionServiceDep,
) -> UserProfile:
"""
Hybrid authentication with subscription validation for CLI access.
Validates JWT (WorkOS or AuthKit) and checks for active subscription.
Returns UserProfile if both checks pass.
Raises:
HTTPException(401): Invalid JWT token
HTTPException(403): No active subscription
"""
# Try WorkOS JWT first (faster validation path)
try:
user_context = await validate_workos_jwt(credentials.credentials)
except HTTPException:
# Fall back to AuthKit JWT validation
try:
user_context = await validate_authkit_jwt(credentials.credentials)
except HTTPException as e:
raise HTTPException(
status_code=401,
detail="Invalid JWT token. Authentication required.",
) from e
# Check subscription status
has_subscription = await subscription_service.check_user_has_active_subscription(
session, user_context.workos_user_id
)
if not has_subscription:
logger.warning(
"CLI access denied: no active subscription",
workos_user_id=user_context.workos_user_id,
)
raise HTTPException(
status_code=403,
detail={
"error": "subscription_required",
"message": "Active subscription required for CLI access",
"subscribe_url": "https://basicmemory.com/subscribe"
}
)
# Look up and return user profile
user_profile = await user_profile_repo.get_user_profile_by_workos_user_id(
session, user_context.workos_user_id
)
if not user_profile:
logger.error(
"User profile not found after successful auth",
workos_user_id=user_context.workos_user_id,
)
raise HTTPException(401, detail="User profile not found")
logger.info(
"CLI access granted",
workos_user_id=user_context.workos_user_id,
user_profile_id=str(user_profile.id),
)
return user_profile
AuthorizedCLIUserProfileDep = Annotated[UserProfile, Depends(get_authorized_cli_user_profile)]
```
#### Task 1.3: Protect tenant mount endpoints ✅
**File**: `apps/cloud/src/basic_memory_cloud/api/tenant_mount.py`
- [x] Update import: add `AuthorizedUserProfileDep` from `..deps`
- [x] Replace `user_profile: CurrentUserProfileHybridJwtDep` with `user_profile: AuthorizedUserProfileDep` in:
- [x] `get_tenant_mount_info()` (line ~23)
- [x] `create_tenant_mount_credentials()` (line ~88)
- [x] `revoke_tenant_mount_credentials()` (line ~244)
- [x] `list_tenant_mount_credentials()` (line ~326)
- [x] Verify no other code changes needed (parameter name and usage stays the same)
- [x] Run `just typecheck` to verify types
#### Task 1.4: Protect proxy endpoints ✅
**File**: `apps/cloud/src/basic_memory_cloud/api/proxy.py`
- [x] Update import: add `AuthorizedUserProfileDep` from `..deps`
- [x] Replace `user_profile: CurrentUserProfileHybridJwtDep` with `user_profile: AuthorizedUserProfileDep` in:
- [x] `check_tenant_health()` (line ~21)
- [x] `proxy_to_tenant()` (line ~63)
- [x] Verify no other code changes needed (parameter name and usage stays the same)
- [x] Run `just typecheck` to verify types
**Why Keep /proxy Architecture:**
The proxy layer is valuable because it:
1. **Centralizes authorization** - Single place for JWT + subscription validation (closes both CLI and MCP auth gaps)
2. **Handles tenant routing** - Maps tenant_id → fly_app_name without exposing infrastructure details
3. **Abstracts infrastructure** - MCP and CLI don't need to know about Fly.io naming conventions
4. **Enables features** - Can add rate limiting, caching, request logging, etc. at proxy layer
5. **Supports both flows** - CLI tools and MCP tools both use /proxy endpoints
The extra HTTP hop is minimal (< 10ms) and worth it for architectural benefits.
**Performance Note:** Cloud app has Redis available - can cache subscription status to reduce database queries if needed. Initial implementation uses direct database query (simple, acceptable performance ~5-10ms).

## Questions to Resolve
### Resolved ✅
1. **Admin Access**
- ✅ **Decision**: Admin users bypass subscription check
- **Rationale**: Admin endpoints already use `AdminUserHybridDep`, which is separate from CLI user endpoints
- **Implementation**: No changes needed to admin endpoints
2. **Subscription Check Implementation**
- ✅ **Decision**: Use Option A (Database Check)
- **Rationale**: Simpler, faster to implement, works with existing infrastructure
- **Implementation**: Single JOIN query via `get_subscription_by_workos_user_id()`
3. **Dependency Return Type**
- ✅ **Decision**: Return `UserProfile` (not `UserContext`)
- **Rationale**: Drop-in compatibility with existing endpoints, no refactoring needed
- **Implementation**: `AuthorizedCLIUserProfileDep` returns `UserProfile`
### To Be Resolved ⏳
1. **Subscription Check Frequency**
- **Options**:
- Check on every API call (slower, more secure) ✅ **RECOMMENDED**
- Cache subscription status (faster, risk of stale data)
- Check only on login/setup (fast, but allows expired subscriptions temporarily)
- **Recommendation**: Check on every call via dependency injection (simple, secure, acceptable performance)
- **Impact**: ~5-10ms per request (single indexed JOIN query)
2. **Grace Period**
- **Options**:
- No grace period - immediate block when status != "active" ✅ **RECOMMENDED**
- 7-day grace period after period_end
- 14-day grace period after period_end
- **Recommendation**: No grace period initially, add later if needed based on customer feedback
- **Implementation**: Check `subscription.status == "active"` only (ignore period_end initially)
3. **Subscription Expiration Handling**
- **Question**: Should we check `current_period_end < now()` in addition to `status == "active"`?
- **Options**:
- Only check status field (rely on Polar webhooks to update status) ✅ **RECOMMENDED**
- Check both status and current_period_end (more defensive)
- **Recommendation**: Only check status field, assume Polar webhooks keep it current
- **Risk**: If webhooks fail, expired subscriptions might retain access until webhook succeeds
4. **Subscribe URL**
- **Question**: What's the actual subscription URL?
- **Current**: Spec uses `https://basicmemory.com/subscribe`
- **Action Required**: Verify correct URL before implementation
5. **Dev Mode / Testing Bypass**
- **Question**: Support bypass for development/testing?
- **Options**:
- Environment variable: `DISABLE_SUBSCRIPTION_CHECK=true`
- Always enforce (more realistic testing) ✅ **RECOMMENDED**
- **Recommendation**: No bypass - use test users with real subscriptions for realistic testing
- **Implementation**: Create dev endpoint to activate subscriptions for testing
## Related Specs
- SPEC-9: Multi-Project Bidirectional Sync Architecture (CLI affected by this change)
- SPEC-8: TigrisFS Integration (Mount endpoints protected)
## Notes
- This spec prioritizes security over convenience - better to block unauthorized access than risk revenue loss
- Clear error messages are critical - users should understand why they're blocked and how to resolve it
- Consider adding telemetry to track subscription_required errors for monitoring signup conversion

# SPEC-19: Sync Performance and Memory Optimization
## Why
### Problem Statement
Current sync implementation causes Out-of-Memory (OOM) kills and poor performance on production systems:
**Evidence from Production**:
- **Tenant-6d2ff1a3**: OOM killed on 1GB machine
- Files: 2,621 total (31 PDFs, 80MB binary data)
- Memory: 1.5-1.7GB peak usage
- Sync duration: 15+ minutes
- Error: `Out of memory: Killed process 693 (python)`
**Root Causes**:
1. **Checksum-based scanning loads ALL files into memory**
- `scan_directory()` computes checksums for ALL 2,624 files upfront
- Results stored in multiple dicts (`ScanResult.files`, `SyncReport.checksums`)
- Even unchanged files are fully read and checksummed
2. **Large files read entirely for checksums**
- 16MB PDF → Full read into memory → Compute checksum
- No streaming or chunked processing
- TigrisFS caching compounds memory usage
3. **Unbounded concurrency**
- All 2,624 files processed simultaneously
- Each file loads full content into memory
- No semaphore limiting concurrent operations
4. **Cloud-specific resource leaks**
- aiohttp session leak in keepalive (not in context manager)
- Circuit breaker resets every 30s sync cycle (ineffective)
- Thundering herd: all tenants sync at :00 and :30
### Impact
- **Production stability**: OOM kills are unacceptable
- **User experience**: 15+ minute syncs are too slow
- **Cost**: Forced upgrades from 1GB → 2GB machines ($5-10/mo per tenant)
- **Scalability**: Current approach won't scale to 100+ tenants
### Architectural Decision
**Fix in basic-memory core first, NOT UberSync**
Rationale:
- Root causes are algorithmic, not architectural
- Benefits all users (CLI + Cloud)
- Lower risk than new centralized service
- Known solutions (rsync/rclone use same pattern)
- Can defer UberSync until metrics prove it necessary
## What
### Affected Components
**basic-memory (core)**:
- `src/basic_memory/sync/sync_service.py` - Core sync algorithm (~42KB)
- `src/basic_memory/models.py` - Entity model (add mtime/size columns)
- `src/basic_memory/file_utils.py` - Checksum computation functions
- `src/basic_memory/repository/entity_repository.py` - Database queries
- `alembic/versions/` - Database migration for schema changes
**basic-memory-cloud (wrapper)**:
- `apps/api/src/basic_memory_cloud_api/sync_worker.py` - Cloud sync wrapper
- Circuit breaker implementation
- Sync coordination logic
### Database Schema Changes
Add to Entity model:
```python
mtime: float # File modification timestamp
size: int # File size in bytes
```
## How (High Level)
### Phase 1: Core Algorithm Fixes (basic-memory)
**Priority: P0 - Critical**
#### 1.1 mtime-based Scanning (Issue #383)
Replace expensive checksum-based scanning with lightweight stat-based comparison:
```python
async def scan_directory(self, directory: Path) -> ScanResult:
"""Scan using mtime/size instead of checksums"""
result = ScanResult()
for root, dirnames, filenames in os.walk(str(directory)):
for filename in filenames:
rel_path = path.relative_to(directory).as_posix()
stat = path.stat()
# Store lightweight metadata instead of checksum
result.files[rel_path] = {
'mtime': stat.st_mtime,
'size': stat.st_size
}
return result
async def scan(self, directory: Path):
"""Compare mtime/size, only compute checksums for changed files"""
db_state = await self.get_db_file_state() # Include mtime/size
scan_result = await self.scan_directory(directory)
for file_path, metadata in scan_result.files.items():
db_metadata = db_state.get(file_path)
# Only compute expensive checksum if mtime/size changed
if not db_metadata or metadata['mtime'] != db_metadata['mtime']:
checksum = await self._compute_checksum_streaming(file_path)
# Process immediately, don't accumulate in memory
```
**Benefits**:
- No file reads during initial scan (just stat calls)
- ~90% reduction in memory usage
- ~10x faster scan phase
- Only checksum files that actually changed
#### 1.2 Streaming Checksum Computation (Issue #382)
For large files (>1MB), use chunked reading to avoid loading entire file:
```python
async def _compute_checksum_streaming(self, path: Path, chunk_size: int = 65536) -> str:
"""Compute checksum using 64KB chunks for large files"""
hasher = hashlib.sha256()
loop = asyncio.get_event_loop()
def read_chunks():
with open(path, 'rb') as f:
while chunk := f.read(chunk_size):
hasher.update(chunk)
await loop.run_in_executor(None, read_chunks)
return hasher.hexdigest()
async def _compute_checksum_async(self, file_path: Path) -> str:
"""Choose appropriate checksum method based on file size"""
stat = file_path.stat()
if stat.st_size > 1_048_576: # 1MB threshold
return await self._compute_checksum_streaming(file_path)
else:
# Small files: existing fast path
content = await self._read_file_async(file_path)
return compute_checksum(content)
```
**Benefits**:
- Constant memory usage regardless of file size
- 16MB PDF uses 64KB memory (not 16MB)
- Works well with TigrisFS network I/O
#### 1.3 Bounded Concurrency (Issue #198)
Add semaphore to limit concurrent file operations, or consider using aiofiles and async reads
```python
class SyncService:
def __init__(self, ...):
# ... existing code ...
self._file_semaphore = asyncio.Semaphore(10) # Max 10 concurrent
self._max_tracked_failures = 100 # LRU cache limit
async def _read_file_async(self, file_path: Path) -> str:
async with self._file_semaphore:
loop = asyncio.get_event_loop()
return await loop.run_in_executor(
self._thread_pool,
file_path.read_text,
"utf-8"
)
async def _record_failure(self, path: str, error: str):
# ... existing code ...
# Implement LRU eviction
if len(self._file_failures) > self._max_tracked_failures:
self._file_failures.popitem(last=False) # Remove oldest
```
**Benefits**:
- Maximum 10 files in memory at once (vs all 2,624)
- 90%+ reduction in peak memory usage
- Prevents unbounded memory growth on error-prone projects
### Phase 2: Cloud-Specific Fixes (basic-memory-cloud)
**Priority: P1 - High**
#### 2.1 Fix Resource Leaks
```python
# apps/api/src/basic_memory_cloud_api/sync_worker.py
async def send_keepalive():
"""Send keepalive pings using proper session management"""
# Use context manager to ensure cleanup
async with aiohttp.ClientSession(
timeout=aiohttp.ClientTimeout(total=5)
) as session:
while True:
try:
await session.get(f"https://{fly_app_name}.fly.dev/health")
await asyncio.sleep(10)
except asyncio.CancelledError:
raise # Exit cleanly
except Exception as e:
logger.warning(f"Keepalive failed: {e}")
```
#### 2.2 Improve Circuit Breaker
Track failures across sync cycles instead of resetting every 30s:
```python
# Persistent failure tracking
class SyncWorker:
def __init__(self):
self._persistent_failures: Dict[str, int] = {} # file -> failure_count
self._failure_window_start = time.time()
async def should_skip_file(self, file_path: str) -> bool:
# Skip files that failed >3 times in last hour
if self._persistent_failures.get(file_path, 0) > 3:
if time.time() - self._failure_window_start < 3600:
return True
return False
```
### Phase 3: Measurement & Decision
**Priority: P2 - Future**
After implementing Phases 1-2, collect metrics for 2 weeks:
- Memory usage per tenant sync
- Sync duration (scan + process)
- Concurrent sync load at peak times
- OOM incidents
- Resource costs
**UberSync Decision Criteria**:
Build centralized sync service ONLY if metrics show:
- ✅ Core fixes insufficient for >100 tenants
- ✅ Resource contention causing problems
- ✅ Need for tenant tier prioritization (paid > free)
- ✅ Cost savings justify complexity
Otherwise, defer UberSync as premature optimization.
## How to Evaluate
### Success Metrics (Phase 1)
**Memory Usage**:
- ✅ Peak memory <500MB for 2,000+ file projects (was 1.5-1.7GB)
- ✅ Memory usage linear with concurrent files (10 max), not total files
- ✅ Large file memory usage: 64KB chunks (not 16MB)
**Performance**:
- ✅ Initial scan <30 seconds (was 5+ minutes)
- ✅ Full sync <5 minutes for 2,000+ files (was 15+ minutes)
- ✅ Subsequent syncs <10 seconds (only changed files)
**Stability**:
- ✅ 2,000+ file projects run on 1GB machines
- ✅ Zero OOM kills in production
- ✅ No degradation with binary files (PDFs, images)
### Success Metrics (Phase 2)
**Resource Management**:
- ✅ Zero aiohttp session leaks (verified via monitoring)
- ✅ Circuit breaker prevents repeated failures (>3 fails = skip for 1 hour)
- ✅ Tenant syncs distributed over 30s window (no thundering herd)
**Observability**:
- ✅ Logfire traces show memory usage per sync
- ✅ Clear logging of skipped files and reasons
- ✅ Metrics on sync duration, file counts, failure rates
### Test Plan
**Unit Tests** (basic-memory):
- mtime comparison logic
- Streaming checksum correctness
- Semaphore limiting (mock 100 files, verify max 10 concurrent)
- LRU cache eviction
- Checksum computation: streaming vs non-streaming equivalence
**Integration Tests** (basic-memory):
- Large file handling (create 20MB test file)
- Mixed file types (text + binary)
- Changed file detection via mtime
- Sync with 1,000+ files
**Load Tests** (basic-memory-cloud):
- Test on tenant-6d2ff1a3 (2,621 files, 31 PDFs)
- Monitor memory during full sync with Logfire
- Measure scan and sync duration
- Run on 1GB machine (downgrade from 2GB to verify)
- Simulate 10 concurrent tenant syncs
**Regression Tests**:
- Verify existing sync scenarios still work
- CLI sync behavior unchanged
- File watcher integration unaffected
### Performance Benchmarks
Establish baseline, then compare after each phase:
| Metric | Baseline | Phase 1 Target | Phase 2 Target |
|--------|----------|----------------|----------------|
| Peak Memory (2,600 files) | 1.5-1.7GB | <500MB | <450MB |
| Initial Scan Time | 5+ min | <30 sec | <30 sec |
| Full Sync Time | 15+ min | <5 min | <5 min |
| Subsequent Sync | 2+ min | <10 sec | <10 sec |
| OOM Incidents/Week | 2-3 | 0 | 0 |
| Min RAM Required | 2GB | 1GB | 1GB |
## Implementation Phases
### Phase 0.5: Database Schema & Streaming Foundation
**Priority: P0 - Required for Phase 1**
This phase establishes the foundation for streaming sync with mtime-based change detection.
**Database Schema Changes**:
- [x] Add `mtime` column to Entity model (REAL type for float timestamp)
- [x] Add `size` column to Entity model (INTEGER type for file size in bytes)
- [x] Create Alembic migration for new columns (nullable initially)
- [x] Add indexes on `(file_path, project_id)` for optimistic upsert performance
- [ ] Backfill existing entities with mtime/size from filesystem
**Streaming Architecture**:
- [x] Replace `os.walk()` with `os.scandir()` for cached stat info
- [ ] Eliminate `get_db_file_state()` - no upfront SELECT all entities
- [x] Implement streaming iterator `_scan_directory_streaming()`
- [x] Add `get_by_file_path()` optimized query (single file lookup)
- [x] Add `get_all_file_paths()` for deletion detection (paths only, no entities)
**Benefits**:
- **50% fewer network calls** on Tigris (scandir returns cached stat)
- **No large dicts in memory** (process files one at a time)
- **Indexed lookups** instead of full table scan
- **Foundation for mtime comparison** (Phase 1)
**Code Changes**:
```python
# Before: Load all entities upfront
db_paths = await self.get_db_file_state() # SELECT * FROM entity WHERE project_id = ?
scan_result = await self.scan_directory() # os.walk() + stat() per file
# After: Stream and query incrementally
async for file_path, stat_info in self.scan_directory(): # scandir() with cached stat
db_entity = await self.entity_repository.get_by_file_path(rel_path) # Indexed lookup
# Process immediately, no accumulation
```
**Files Modified**:
- `src/basic_memory/models.py` - Add mtime/size columns
- `alembic/versions/xxx_add_mtime_size.py` - Migration
- `src/basic_memory/sync/sync_service.py` - Streaming implementation
- `src/basic_memory/repository/entity_repository.py` - Add get_all_file_paths()
**Migration Strategy**:
```sql
-- Migration: Add nullable columns
ALTER TABLE entity ADD COLUMN mtime REAL;
ALTER TABLE entity ADD COLUMN size INTEGER;
-- Backfill from filesystem during first sync after upgrade
-- (Handled in sync_service on first scan)
```

- [x] Removed `sync_status_service.py` and `sync_status` MCP tool
- [x] Removed all `sync_status_tracker` calls from `sync_service.py`
- [x] Removed migration status checks from MCP tools (`write_note`, `read_note`, `build_context`)
- [x] Removed `check_migration_status()` and `wait_for_migration_or_return_status()` from `utils.py`
- [x] Removed all related tests (4 test files deleted)
- [x] All 1184 tests passing
**Phase 1 Implementation Summary:**
Phase 1 is now complete with all core fixes implemented and tested:
1. **Streaming Architecture** (Phase 0.5 + Phase 1):
- Replaced `os.walk()` with `os.scandir()` for cached stat info
- Eliminated upfront `get_db_file_state()` SELECT query
- Implemented `_scan_directory_streaming()` for incremental processing
- Added indexed `get_by_file_path()` lookups
- Result: 50% fewer network calls on TigrisFS, no large dicts in memory
2. **mtime-based Change Detection**:
- Added `mtime` and `size` columns to Entity model
- Alembic migration completed and deployed
- Only compute checksums when mtime/size differs from database
- Result: ~90% reduction in checksum operations during typical syncs
3. **True Async I/O with aiofiles**:
- All file operations consolidated in FileService
- `FileService.compute_checksum()`: 64KB chunked reading for constant memory (lines 261-296 of file_service.py)
- `FileService.read_file_content()`: Non-blocking file reads with aiofiles (lines 160-193 of file_service.py)
- Removed all wrapper methods from SyncService (`_read_file_async`, `_compute_checksum_async`)
- Semaphore controls concurrency (max 10 concurrent file operations)
- Result: Constant memory usage regardless of file size, true non-blocking I/O
4. **Test Coverage**:
- 41/43 sync tests passing (2 skipped as expected)
- Circuit breaker tests updated for new architecture
- Streaming checksum equivalence verified
- All edge cases covered (large files, concurrent operations, failures)
**Key Files Modified**:
- `src/basic_memory/models.py` - Added mtime/size columns
- `alembic/versions/xxx_add_mtime_size.py` - Database migration
- `src/basic_memory/sync/sync_service.py` - Streaming implementation, removed wrapper methods
- `src/basic_memory/services/file_service.py` - Added `read_file_content()`, streaming checksums
- `src/basic_memory/repository/entity_repository.py` - Added `get_all_file_paths()`
- `tests/sync/test_sync_service.py` - Updated circuit breaker test mocks
**Performance Improvements Achieved**:

- I/O efficiency: True async with aiofiles (no thread pool blocking)
- Network efficiency: 50% fewer calls on TigrisFS via scandir caching
- Architecture: Clean separation of concerns (FileService owns all file I/O)
- Reduced complexity: Removed unnecessary sync_status_service state tracking
**Observability**:
- [x] Added Logfire instrumentation to `sync_file()` and `sync_markdown_file()`
- [x] Logfire disabled by default via `ignore_no_config = true` in pyproject.toml
- [x] No telemetry in FOSS version unless explicitly configured
- [x] Cloud deployment can enable Logfire for performance monitoring
**Next Steps**: Phase 1.5 scan watermark optimization for large project performance.
### Phase 1.5: Scan Watermark Optimization
**Priority: P0 - Critical for Large Projects**
This phase addresses Issue #388 where large projects (1,460+ files) take 7+ minutes for sync operations even when no files have changed.
**Problem Analysis**:
From production data (tenant-0a20eb58):
- Total sync time: 420-450 seconds (7+ minutes) with 0 changes
- Scan phase: 321 seconds (75% of total time)
- Per-file cost: 220ms × 1,460 files = 5+ minutes
- Root cause: Network I/O to TigrisFS for stat operations (even with mtime columns)
- 15 concurrent syncs every 30 seconds compounds the problem
**Current Behavior** (Phase 1):
```python
async def scan(self, directory: Path):
"""Scan filesystem using mtime/size comparison"""
# Still stats ALL 1,460 files every sync cycle
async for file_path, stat_info in self._scan_directory_streaming():
db_entity = await self.entity_repository.get_by_file_path(file_path)
# Compare mtime/size, skip unchanged files
# Only checksum if changed (✅ already optimized)
```
**Problem**: Even with mtime optimization, we stat every file on every scan. On TigrisFS (network FUSE mount), this means 1,460 network calls taking 5+ minutes.
**Solution: Scan Watermark + File Count Detection**
Track when we last scanned and how many files existed. Use filesystem-level filtering to only examine files modified since last scan.
**Key Insight**: File count changes signal deletions
- Count same → incremental scan (95% of syncs)
- Count increased → new files found by incremental (4% of syncs)
- Count decreased → files deleted, need full scan (1% of syncs)
**Database Schema Changes**:
Add to Project model:
```python
last_scan_timestamp: float | None # Unix timestamp of last successful scan start
last_file_count: int | None # Number of files found in last scan
```
**Implementation Strategy**:
```python
async def scan(self, directory: Path):
"""Smart scan using watermark and file count"""
project = await self.project_repository.get_current()
# Step 1: Quick file count (fast on TigrisFS: 1.4s for 1,460 files)
current_count = await self._quick_count_files(directory)
# Step 2: Determine scan strategy
if project.last_file_count is None:
# First sync ever → full scan
file_paths = await self._scan_directory_full(directory)
scan_type = "full_initial"
elif current_count < project.last_file_count:
# Files deleted → need full scan to detect which ones
file_paths = await self._scan_directory_full(directory)
scan_type = "full_deletions"
logger.info(f"File count decreased ({project.last_file_count} → {current_count}), running full scan")
elif project.last_scan_timestamp is not None:
# Incremental scan: only files modified since last scan
file_paths = await self._scan_directory_modified_since(
directory,
project.last_scan_timestamp
)
scan_type = "incremental"
logger.info(f"Incremental scan since {project.last_scan_timestamp}, found {len(file_paths)} changed files")
else:
# Fallback to full scan
file_paths = await self._scan_directory_full(directory)
scan_type = "full_fallback"
# Step 3: Process changed files (existing logic)
for file_path in file_paths:
await self._process_file(file_path)
# Step 4: Update watermark AFTER successful scan
await self.project_repository.update(
project.id,
last_scan_timestamp=time.time(), # Start of THIS scan
last_file_count=current_count
)
# Step 5: Record metrics
logfire.metric_counter(f"sync.scan.{scan_type}").add(1)
logfire.metric_histogram("sync.scan.files_scanned", unit="files").record(len(file_paths))
```
**Helper Methods**:
```python
async def _quick_count_files(self, directory: Path) -> int:
"""Fast file count using find command"""
# TigrisFS: 1.4s for 1,460 files
result = await asyncio.create_subprocess_shell(
f'find "{directory}" -type f | wc -l',
stdout=asyncio.subprocess.PIPE
)
stdout, _ = await result.communicate()
return int(stdout.strip())
async def _scan_directory_modified_since(
self,
directory: Path,
since_timestamp: float
) -> List[str]:
"""Use find -newermt for filesystem-level filtering"""
# Convert timestamp to find-compatible format
since_date = datetime.fromtimestamp(since_timestamp).strftime("%Y-%m-%d %H:%M:%S")
# TigrisFS: 0.2s for 0 changed files (vs 5+ minutes for full scan)
result = await asyncio.create_subprocess_shell(
f'find "{directory}" -type f -newermt "{since_date}"',
stdout=asyncio.subprocess.PIPE
)
stdout, _ = await result.communicate()
# Convert absolute paths to relative
file_paths = []
for line in stdout.decode().splitlines():
if line:
rel_path = Path(line).relative_to(directory).as_posix()
file_paths.append(rel_path)
return file_paths
```
**TigrisFS Testing Results** (SSH to production-basic-memory-tenant-0a20eb58):
```bash
# Full file count
$ time find . -type f | wc -l
1460
real 0m1.362s # ✅ Acceptable
# Incremental scan (1 hour window)
$ time find . -type f -newermt "2025-01-20 10:00:00" | wc -l
0
real 0m0.161s # ✅ 8.5x faster!
# Incremental scan (24 hours)
$ time find . -type f -newermt "2025-01-19 11:00:00" | wc -l
0
real 0m0.239s # ✅ 5.7x faster!
```
**Conclusion**: `find -newermt` works perfectly on TigrisFS and provides massive speedup.
**Expected Performance Improvements**:
| Scenario | Files Changed | Current Time | With Watermark | Speedup |
|----------|---------------|--------------|----------------|---------|
| No changes (common) | 0 | 420s | ~2s | 210x |
| Few changes | 5-10 | 420s | ~5s | 84x |
| Many changes | 100+ | 420s | ~30s | 14x |
| Deletions (rare) | N/A | 420s | 420s | 1x |
**Full sync breakdown** (1,460 files, 0 changes):
- File count: 1.4s
- Incremental scan: 0.2s
- Database updates: 0.4s
- **Total: ~2s (225x faster)**
**Metrics to Track**:
```python
# Scan type distribution
logfire.metric_counter("sync.scan.full_initial").add(1)
logfire.metric_counter("sync.scan.full_deletions").add(1)
logfire.metric_counter("sync.scan.incremental").add(1)
# Performance metrics
logfire.metric_histogram("sync.scan.duration", unit="ms").record(scan_ms)
logfire.metric_histogram("sync.scan.files_scanned", unit="files").record(file_count)
logfire.metric_histogram("sync.scan.files_changed", unit="files").record(changed_count)
# Watermark effectiveness
logfire.metric_histogram("sync.scan.watermark_age", unit="s").record(
time.time() - project.last_scan_timestamp
)
```
**Edge Cases Handled**:
1. **First sync**: No watermark → full scan (expected)
2. **Deletions**: File count decreased → full scan (rare but correct)
3. **Clock skew**: Use scan start time, not end time (captures files created during scan)
4. **Scan failure**: Don't update watermark on failure (retry will re-scan)
5. **New files**: Count increased → incremental scan finds them (common, fast)
**Files to Modify**:

## References
**Standard sync tools using mtime**:
- rsync: Uses mtime-based comparison by default, only checksums on `--checksum` flag
- rclone: Default is mtime/size, `--checksum` mode optional
- syncthing: Block-level sync with mtime tracking
**fsnotify polling** (future consideration):
- [fsnotify/fsnotify#9](https://github.com/fsnotify/fsnotify/issues/9) - Polling mode for network filesystems
## Notes
### Why Not UberSync Now?
**Premature Optimization**:
- Current problems are algorithmic, not architectural
- No evidence that multi-tenant coordination is the issue
- Single tenant OOM proves algorithm is the problem
**Benefits of Core-First Approach**:
- ✅ Helps all users (CLI + Cloud)
- ✅ Lower risk (no new service)
- ✅ Clear path (issues specify fixes)
- ✅ Can defer UberSync until proven necessary
**When UberSync Makes Sense**:
- >100 active tenants causing resource contention
- Need for tenant tier prioritization (paid > free)
- Centralized observability requirements
- Cost optimization at scale
### Migration Strategy
**Backward Compatibility**:
- New mtime/size columns nullable initially
- Existing entities sync normally (compute mtime on first scan)
- No breaking changes to MCP API
- CLI behavior unchanged
**Rollout**:
1. Deploy to staging with test tenant
2. Validate memory/performance improvements
3. Deploy to production (blue-green)
4. Monitor for 1 week
5. Downgrade tenant machines if successful
## Further Considerations
### Version Control System (VCS) Integration
**Context:** Users frequently request git versioning, and large projects with PDFs/images pose memory challenges.
#### Git-Based Sync
**Approach:** Use git for change detection instead of custom mtime comparison.
```python
# Git automatically tracks changes
repo = git.Repo(project_path)
repo.git.add(A=True)
diff = repo.index.diff('HEAD')
for change in diff:
if change.change_type == 'M': # Modified
await sync_file(change.b_path)
```
**Pros:**
- ✅ Proven, battle-tested change detection
- ✅ Built-in rename/move detection (similarity index)
- ✅ Efficient for cloud sync (git protocol over HTTP)
- ✅ Could enable version history as bonus feature
- ✅ Users want git integration anyway
**Cons:**
- ❌ User confusion (`.git` folder in knowledge base)
- ❌ Conflicts with existing git repos (submodule complexity)
- ❌ Adds dependency (git binary or dulwich/pygit2)
- ❌ Less control over sync logic
- ❌ Doesn't solve large file problem (PDFs still checksummed)
- ❌ Git LFS adds complexity
#### Jujutsu (jj) Alternative
**Why jj is compelling:**
1. **Working Copy as Source of Truth**
- Git: Staging area is intermediate state
- Jujutsu: Working copy IS a commit
- Aligns with "files are source of truth" philosophy!
2. **Automatic Change Tracking**
- No manual staging required
- Working copy changes tracked automatically
- Better fit for sync operations vs git's commit-centric model
3. **Conflict Handling**
- User edits + sync changes both preserved
- Operation log vs linear history
- Built for operations, not just history
**Cons:**
- ❌ New/immature (2020 vs git's 2005)
- ❌ Not universally available
- ❌ Steeper learning curve for users
- ❌ No LFS equivalent yet
- ❌ Still doesn't solve large file checksumming
#### Git Index Format (Hybrid Approach)
**Best of both worlds:** Use git's index format without full git repo.
```python
from dulwich.index import Index # Pure Python
# Use git index format for tracking
idx = Index(project_path / '.basic-memory' / 'index')
for file in files:
stat = file.stat()
if idx.get(file) and idx[file].mtime == stat.st_mtime:
continue # Unchanged (git's proven logic)
await sync_file(file)
idx[file] = (stat.st_mtime, stat.st_size, sha)
```
**Pros:**
- ✅ Git's proven change detection logic
- ✅ No user-visible `.git` folder
- ✅ No git dependency (pure Python)
- ✅ Full control over sync
**Cons:**
- ❌ Adds dependency (dulwich)
- ❌ Doesn't solve large files
- ❌ No built-in versioning
### Large File Handling
**Problem:** PDFs/images cause memory issues regardless of VCS choice.
**Solutions (Phase 1+):**
**1. Skip Checksums for Large Files**
```python
if stat.st_size > 10_000_000: # 10MB threshold
checksum = None # Use mtime/size only
logger.info(f"Skipping checksum for {file_path}")
```
**2. Partial Hashing**
```python
if file.suffix in ['.pdf', '.jpg', '.png']:
# Hash first/last 64KB instead of entire file
checksum = hash_partial(file, chunk_size=65536)
```
**3. External Blob Storage**
```python
if stat.st_size > 10_000_000:
blob_id = await upload_to_tigris_blob(file)
entity.blob_id = blob_id
entity.file_path = None # Not in main sync
```
### Recommendation & Timeline
**Phase 0.5-1 (Now):** Custom streaming + mtime
- ✅ Solves urgent memory issues
- ✅ No dependencies
- ✅ Full control
- ✅ Skip checksums for large files (>10MB)
- ✅ Proven pattern (rsync/rclone)
**Phase 2 (After metrics):** Git index format exploration
```python
# Optional: Use git index for tracking if beneficial
from dulwich.index import Index
# No git repo, just index file format
```
**Future (User feature):** User-facing versioning
```python
# Let users opt into VCS:
basic-memory config set versioning git
basic-memory config set versioning jj
basic-memory config set versioning none # Current behavior
# Integrate with their chosen workflow
# Not forced upon them
```
**Rationale:**
1. **Don't block on VCS decision** - Memory issues are P0
2. **Learn from deployment** - See actual usage patterns
3. **Keep options open** - Can add git/jj later
4. **Files as source of truth** - Core philosophy preserved
5. **Large files need attention regardless** - VCS won't solve that
**Decision Point:**
- If Phase 0.5/1 achieves memory targets → VCS integration deferred
- If users strongly request versioning → Add as opt-in feature
- If change detection becomes bottleneck → Explore git index format
## Agent Assignment
**Phase 1 Implementation**: `python-developer` agent
- Expertise in FastAPI, async Python, database migrations
- Handles basic-memory core changes
**Phase 2 Implementation**: `python-developer` agent
- Same agent continues with cloud-specific fixes
- Maintains consistency across phases
**Phase 3 Review**: `system-architect` agent
- Analyzes metrics and makes UberSync decision
- Creates SPEC-18 if centralized service needed
