+# SPEC-10: Unified Deployment Workflow and Event Tracking
+
+## Why
+
+We replaced a complex multi-workflow system with DBOS orchestration that was proving to be more trouble than it was worth. The previous architecture had four separate workflows (`tenant_provisioning`, `tenant_update`, `tenant_deployment`, `tenant_undeploy`) with overlapping logic, complex state management, and fragmented event tracking. DBOS added unnecessary complexity without providing sufficient value, leading to harder debugging and maintenance.
+
+**Problems Solved:**
+- **Framework Complexity**: DBOS configuration overhead and fighting framework limitations
+- **Code Duplication**: Multiple workflows implementing similar operations with duplicate logic
+- **Poor Observability**: Fragmented event tracking across workflow boundaries
+- **Maintenance Overhead**: Complex orchestration for fundamentally simple operations
+- **Debugging Difficulty**: Framework abstractions hiding simple Python stack traces
+
+## What
+
+This spec documents the architectural simplification that consolidates tenant lifecycle management into a unified system with comprehensive event tracking.
+
+**Affected Areas:**
+- Tenant deployment workflows (provisioning, updates, undeploying)
+- Event sourcing and workflow tracking infrastructure
+- API endpoints for tenant operations
+- Database schema for workflow and event correlation
+- Integration testing for tenant lifecycle operations
+
+**Key Changes:**
+- **Removed DBOS entirely** - eliminated framework dependency and complexity
+- **Consolidated 4 workflows → 2 unified deployment workflows (deploy/undeploy)**
+- **Added workflow tracking system** with complete event correlation
+- **Simplified API surface** - single `/deploy` endpoint handles all scenarios
+- **Enhanced observability** through event sourcing with workflow grouping
+
+## How (High Level)
+
+### Architectural Philosophy
+**Embrace simplicity over framework complexity** - use well-structured Python with proper database design instead of complex orchestration frameworks.
+
+### Core Components
+
+#### 1. Unified Deployment Workflow
+```python
+class TenantDeploymentWorkflow:
+    async def deploy_tenant_workflow(self, tenant_id: str, workflow_id: UUID, image_tag: str = None):
+        # Single workflow handles both initial provisioning AND updates
+        # Each step is idempotent and handles its own error recovery
+        # Database transactions provide the durability we need
+        await self.start_deployment_step(workflow_id, tenant_uuid, image_tag)
+        await self.create_fly_app_step(workflow_id, tenant_uuid)
+        await self.create_bucket_step(workflow_id, tenant_uuid)
+        await self.deploy_machine_step(workflow_id, tenant_uuid, image_tag)
+        await self.complete_deployment_step(workflow_id, tenant_uuid, image_tag, deployment_time)
+```
+
+**Key Benefits:**
+- **Handles both provisioning and updates** in single workflow
+- **Idempotent operations** - safe to retry any step
+- **Clean error handling** via simple Python exceptions
+- **Resumable** - can restart from any failed step
+
+#### 2. Workflow Tracking System
+
+**Database Schema:**
+```sql
+CREATE TABLE workflow (
+    id UUID PRIMARY KEY,
+    workflow_type VARCHAR(50) NOT NULL,  -- 'tenant_deployment', 'tenant_undeploy'
+    tenant_id UUID REFERENCES tenant(id),
+    status VARCHAR(20) DEFAULT 'running', -- 'running', 'completed', 'failed'
+    workflow_metadata JSONB DEFAULT '{}'  -- image_tag, etc.
+);
+
+ALTER TABLE event ADD COLUMN workflow_id UUID REFERENCES workflow(id);
+```
+
+**Event Correlation:**
+- Every workflow operation generates events tagged with `workflow_id`
+- Complete audit trail from workflow start to completion
+- Events grouped by workflow for easy reconstruction of operations
+
+#### 3. Parameter Standardization
+All workflow methods follow consistent signature pattern:
+```python
+async def method_name(self, session: AsyncSession, workflow_id: UUID | None, tenant_id: UUID, ...)
+```
+
+**Benefits:**
+- **Consistent event tagging** - all events properly correlated
+- **Clear method contracts** - workflow_id always first parameter
+- **Type safety** - proper UUID handling throughout

+# API Layer: Return immediately with job tracking
+@router.post("/{tenant_id}/deploy")
+async def deploy_tenant(tenant_id: UUID):
+    # Create workflow record in Postgres
+    workflow = await workflow_repo.create_workflow("tenant_deployment", tenant_id)
+
+    # Enqueue job in Redis
+    job = await arq_pool.enqueue_job('deploy_tenant_task', tenant_id, workflow.id)
+
+    # Return job ID immediately
+    return {"job_id": job.job_id, "workflow_id": workflow.id, "status": "queued"}
+
+# Background Worker: Process via existing unified workflow
+async def deploy_tenant_task(ctx, tenant_id: str, workflow_id: str):
+    # Existing workflow logic - zero changes needed!
+    await workflow_manager.deploy_tenant(UUID(tenant_id), workflow_id=UUID(workflow_id))

+- **Workers**: arq worker processes (new deployment target)
+- **Monitoring**: Job status dashboard (simple web interface)
+
+#### API Evolution
+```python
+# Before: Synchronous (blocks for 60+ seconds)
+POST /tenant/{id}/deploy → {status: "active", machine_id: "..."}
+
+# After: Asynchronous (returns immediately)
+POST /tenant/{id}/deploy → {job_id: "uuid", workflow_id: "uuid", status: "queued"}
+GET  /jobs/{job_id}/status → {status: "running", progress: "deploying_machine", workflow_id: "uuid"}
+GET  /workflows/{workflow_id}/events → [...] # Existing event tracking works unchanged
+```
+
+**Technology Choice**: **arq (Redis)** over pgqueuer
+- **Existing Redis infrastructure** - Upstash + docker-compose already configured
+- **Better ecosystem** - monitoring tools, documentation, community
+- **Made by pydantic team** - aligns with existing Python stack
+- **Hybrid approach** - Redis for queue operations + Postgres for workflow state
+
+#### Job Uniqueness Implementation
+
+**Problem**: Multiple concurrent deployment requests for the same tenant could create duplicate jobs, wasting resources and potentially causing conflicts.
+
+**Solution**: Leverage ARQ's built-in job uniqueness feature using predictable job IDs:
+
+```python
+# JobQueueService implementation
+async def enqueue_deploy_job(self, tenant_id: UUID, image_tag: str | None = None) -> str:
+    unique_job_id = f"deploy-{tenant_id}"
+
+    job = await self.redis_pool.enqueue_job(
+        "deploy_tenant_job",
+        str(tenant_id),
+        image_tag,
+        _job_id=unique_job_id,  # ARQ prevents duplicates
+    )
+
+    if job is None:
+        # Job already exists - return existing job ID
+        return unique_job_id
+    else:
+        # New job created - return ARQ job ID
+        return job.job_id
+```
+
+**Key Features:**
+- **Predictable Job IDs**: `deploy-{tenant_id}`, `undeploy-{tenant_id}`
+- **Duplicate Prevention**: ARQ returns `None` for duplicate job IDs
+- **Graceful Handling**: Return existing job ID instead of raising errors
+- **Idempotent Operations**: Safe to retry deployment requests
+- **Clear Logging**: Distinguish "Enqueued new" vs "Found existing" jobs
+
+**Benefits:**
+- Prevents resource waste from duplicate deployments
+- Eliminates race conditions from concurrent requests
+- Makes job monitoring more predictable with consistent IDs
+- Provides natural deduplication without complex locking mechanisms
+
+
+## Notes
+
+### Design Philosophy Lessons
+- **Simplicity beats framework magic** - removing DBOS made the system more reliable and debuggable
+- **Event sourcing > complex orchestration** - database-backed event tracking provides better observability than framework abstractions
+- **Idempotent operations > resumable workflows** - each step handling its own retry logic is simpler than framework-managed resumability
+- **Explicit error handling > framework exception handling** - Python exceptions are clearer than orchestration framework error states
+
+### Future Considerations
+- **Monitoring integration** - workflow tracking events could feed into observability systems
+- **Performance optimization** - event querying patterns may benefit from additional indexing
+- **Audit compliance** - complete event trail supports regulatory requirements
+- **Operational dashboards** - workflow status could drive tenant health monitoring
+
+### Related Specifications
+- **SPEC-8**: TigrisFS Integration - bucket provisioning integrated with deployment workflow
+- **SPEC-1**: Specification-Driven Development Process - this spec follows the established format

+- **Redis Configuration**: Add Redis settings to existing `apps/cloud/src/basic_memory_cloud/config.py`
+- **Local Development**: Leverage existing Redis setup from `docker-compose.yml`
+- **Production**: Use Upstash Redis configuration for production environments
+
+### Docker Entrypoint Strategy
+Create `entrypoint.sh` script to toggle between API server and worker processes using single Docker image:
+
+```bash
+#!/bin/bash
+
+# Entrypoint script for Basic Memory Cloud service
+# Supports multiple process types: api, worker
+
+set -e
+
+case "$1" in
+  "api")
+    echo "Starting Basic Memory Cloud API server..."
+    exec uvicorn basic_memory_cloud.main:app \
+      --host 0.0.0.0 \
+      --port 8000 \
+      --log-level info
+    ;;
+  "worker")
+    echo "Starting Basic Memory Cloud ARQ worker..."
+    # For ARQ worker implementation
+    exec python -m arq basic_memory_cloud.jobs.settings.WorkerSettings
+    ;;
+  *)
+    echo "Usage: $0 {api|worker}"
+    echo "  api    - Start the FastAPI server"
+    echo "  worker - Start the ARQ worker"
+    exit 1
+    ;;
+esac
+```
+
+### Fly.io Process Groups Configuration
+Use separate machine groups for API and worker processes with independent scaling:
+
+```toml
+# fly.toml app configuration for basic-memory-cloud
+app = 'basic-memory-cloud-dev-basic-machines'
+primary_region = 'dfw'
+org = 'basic-machines'
+kill_signal = 'SIGINT'
+kill_timeout = '5s'
+
+[build]
+
+# Process groups for API server and worker
+[processes]
+  api = "api"
+  worker = "worker"
+
+# Machine scaling configuration
+[[machine]]
+  size = 'shared-cpu-1x'
+  processes = ['api']
+  min_machines_running = 1
+  auto_stop_machines = false
+  auto_start_machines = true
+
+[[machine]]
+  size = 'shared-cpu-1x'
+  processes = ['worker']
+  min_machines_running = 1
+  auto_stop_machines = false
+  auto_start_machines = true
+
+[env]
+  # Python configuration
+  PYTHONUNBUFFERED = '1'
+  PYTHONPATH = '/app'
+
+  # Logging configuration
+  LOG_LEVEL = 'DEBUG'
+
+  # Redis configuration for ARQ
+  REDIS_URL = 'redis://basic-memory-cloud-redis.upstash.io'
+
+  # Database configuration
+  DATABASE_HOST = 'basic-memory-cloud-db-dev-basic-machines.internal'
+  DATABASE_PORT = '5432'
+  DATABASE_NAME = 'basic_memory_cloud'
+  DATABASE_USER = 'postgres'
+  DATABASE_SSL = 'true'
+
+  # Worker configuration
+  ARQ_MAX_JOBS = '10'
+  ARQ_KEEP_RESULT = '3600'
+
+  # Fly.io configuration
+  FLY_ORG = 'basic-machines'
+  FLY_REGION = 'dfw'
+
+# Internal service - no external HTTP exposure for worker
+# API accessible via basic-memory-cloud-dev-basic-machines.flycast:8000
+
+[[vm]]
+  size = 'shared-cpu-1x'
+```
+
+### Benefits of This Architecture

+# SPEC-12: OpenTelemetry Observability
+
+## Why
+
+We need comprehensive observability for basic-memory-cloud to:
+- Track request flows across our multi-tenant architecture (MCP → Cloud → API services)
+- Debug performance issues and errors in production
+- Understand user behavior and system usage patterns
+- Correlate issues to specific tenants for targeted debugging
+- Monitor service health and latency across the distributed system
+
+Currently, we only have basic logging without request correlation or distributed tracing capabilities.
+
+## What
+
+Implement OpenTelemetry instrumentation across all basic-memory-cloud services with:
+
+### Core Requirements
+1. **Distributed Tracing**: End-to-end request tracing from MCP gateway through to tenant API instances
+2. **Tenant Correlation**: All traces tagged with tenant_id, user_id, and workos_user_id
+3. **Service Identification**: Clear service naming and namespace separation
+4. **Auto-instrumentation**: Automatic tracing for FastAPI, SQLAlchemy, HTTP clients
+5. **Grafana Cloud Integration**: Direct OTLP export to Grafana Cloud Tempo
+
+### Services to Instrument
+- **MCP Gateway** (basic-memory-mcp): Entry point with JWT extraction
+- **Cloud Service** (basic-memory-cloud): Provisioning and management operations
+- **API Service** (basic-memory-api): Tenant-specific instances
+- **Worker Processes** (ARQ workers): Background job processing
+
+### Key Trace Attributes
+- `tenant.id`: UUID from UserProfile.tenant_id
+- `user.id`: WorkOS user identifier
+- `user.email`: User email for debugging
+- `service.name`: Specific service identifier
+- `service.namespace`: Environment (development/production)
+- `operation.type`: Business operation (provision/update/delete)
+- `tenant.app_name`: Fly.io app name for tenant instances
+
+## How
+
+### Phase 1: Setup OpenTelemetry SDK
+1. Add OpenTelemetry dependencies to each service's pyproject.toml:
+   ```python
+   "opentelemetry-distro[otlp]>=1.29.0",
+   "opentelemetry-instrumentation-fastapi>=0.50b0",
+   "opentelemetry-instrumentation-httpx>=0.50b0",
+   "opentelemetry-instrumentation-sqlalchemy>=0.50b0",
+   "opentelemetry-instrumentation-logging>=0.50b0",
+   ```
+
+2. Create shared telemetry initialization module (`apps/shared/telemetry.py`)
+
+3. Configure Grafana Cloud OTLP endpoint via environment variables:
+   ```bash
+   OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp-gateway-prod-us-east-2.grafana.net/otlp
+   OTEL_EXPORTER_OTLP_HEADERS=Authorization=Basic[token]
+   OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
+   ```
+
+### Phase 2: Instrument MCP Gateway
+1. Extract tenant context from AuthKit JWT in middleware
+2. Create root span with tenant attributes
+3. Propagate trace context to downstream services via headers
+
+### Phase 3: Instrument Cloud Service
+1. Continue trace from MCP gateway
+2. Add operation-specific attributes (provisioning events)
+3. Instrument ARQ worker jobs for async operations
+4. Track Fly.io API calls and latency
+
+### Phase 4: Instrument API Service
+1. Extract tenant context from JWT
+2. Add machine-specific metadata (instance ID, region)
+3. Instrument database operations with SQLAlchemy
+4. Track MCP protocol operations
+
+### Phase 5: Configure and Deploy
+1. Add OTLP configuration to `.env.example` and `.env.example.secrets`
+2. Set Fly.io secrets for production deployment
+3. Update Dockerfiles to use `opentelemetry-instrument` wrapper
+4. Deploy to development environment first for testing
+
+## How to Evaluate
+
+### Success Criteria
+1. **End-to-end traces visible in Grafana Cloud** showing complete request flow
+2. **Tenant filtering works** - Can filter traces by tenant_id to see all requests for a user
+3. **Service maps accurate** - Grafana shows correct service dependencies
+4. **Performance overhead < 5%** - Minimal latency impact from instrumentation
+5. **Error correlation** - Can trace errors back to specific tenant and operation
+
+### Testing Checklist
+- [x] Single request creates connected trace across all services
+- [x] Tenant attributes present on all spans
+- [x] Background jobs (ARQ) appear in traces
+- [x] Database queries show in trace timeline
+- [x] HTTP calls to Fly.io API tracked
+- [x] Traces exported successfully to Grafana Cloud
+- [x] Can search traces by tenant_id in Grafana
+- [x] Service dependency graph shows correct flow
+
+### Monitoring Success
+- All services reporting traces to Grafana Cloud
+- No OTLP export errors in logs
+- Trace sampling working correctly (if implemented)
+- Resource usage acceptable (CPU/memory)
+
+## Dependencies
+- Grafana Cloud account with OTLP endpoint configured
+- OpenTelemetry Python SDK v1.29.0+
+- FastAPI instrumentation compatibility
+- Network access from Fly.io to Grafana Cloud
+
+## Implementation Assignment
+**Recommended Agent**: python-developer
+- Requires Python/FastAPI expertise
+- Needs understanding of distributed systems
+- Must implement middleware and context propagation
+- Should understand OpenTelemetry SDK and instrumentation
+
+## Follow-up Tasks
+
+### Enhanced Log Correlation
+While basic trace-to-log correlation works automatically via OpenTelemetry logging instrumentation, consider adding structured logging for improved log filtering:
+
+1. **Structured Logging Context**: Add `logger.bind()` calls to inject tenant/user context directly into log records
+2. **Custom Loguru Formatter**: Extract OpenTelemetry span attributes for better log readability
+3. **Direct Log Filtering**: Enable searching logs directly by tenant_id, workflow_id without going through traces
+
+This would complement the existing automatic trace correlation and provide better log search capabilities.
+
+## Alternative Solution: Logfire
+
+After implementing OpenTelemetry with Grafana Cloud, we discovered limitations in the observability experience:
+- Traces work but lack useful context without correlated logs
+- Setting up log correlation with Grafana is complex and requires additional infrastructure
+- The developer experience for Python observability is suboptimal
+
+### Logfire Evaluation
+
+**Pydantic Logfire** offers a compelling alternative that addresses your specific requirements:
+
+#### Core Requirements Match
+- ✅ **User Activity Tracking**: Automatic request tracing with business context
+- ✅ **Error Monitoring**: Built-in exception tracking with full context
+- ✅ **Performance Metrics**: Automatic latency and performance monitoring
+- ✅ **Request Tracing**: Native distributed tracing across services
+- ✅ **Log Correlation**: Seamless trace-to-log correlation without setup
+
+#### Key Advantages
+1. **Python-First Design**: Built specifically for Python/FastAPI applications by the Pydantic team
+2. **Simple Integration**: `pip install logfire` + `logfire.configure()` vs complex OTLP setup
+3. **Automatic Correlation**: Logs automatically include trace context without manual configuration
+4. **Real-time SQL Interface**: Query spans and logs using SQL with auto-completion
+5. **Better Developer UX**: Purpose-built observability UI vs generic Grafana dashboards
+6. **Loguru Integration**: `logger.configure(handlers=[logfire.loguru_handler()])` maintains existing logging
+
+#### Pricing Assessment
+- **Free Tier**: 10M spans/month (suitable for development and small production workloads)
+- **Transparent Pricing**: $1 per million spans/metrics after free tier
+- **No Hidden Costs**: No per-host fees, only usage-based metering
+- **Production Ready**: Recently exited beta, enterprise features available
+
+#### Migration Path
+The existing OpenTelemetry instrumentation is compatible - Logfire uses OpenTelemetry under the hood, so the current spans and attributes would work unchanged.
+
+### Recommendation
+
+**Consider migrating to Logfire** for the following reasons:
+1. It directly addresses the "next to useless" traces problem by providing integrated logs
+2. Dramatically simpler setup and maintenance compared to Grafana Cloud + custom log correlation
+3. Better ROI on observability investment with purpose-built Python tooling
+4. Free tier sufficient for current development needs with clear scaling path
+
+The current Grafana Cloud implementation provides a solid foundation and could remain as a backup/export target, while Logfire becomes the primary observability platform.
+
+## Status
+**Created**: 2024-01-28
+**Status**: Completed (OpenTelemetry + Grafana Cloud)
+**Next Phase**: Evaluate Logfire migration
+**Priority**: High - Critical for production observability

 - 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

-## Implementation Log
-
-### Phase 2 Completion - 2025-10-03
-
-Phase 2 (CLI Updates) completed successfully with the following implementation:
-
-**Files Modified:**
-- `src/basic_memory/cli/commands/cloud/api_client.py` - Added `SubscriptionRequiredError` exception and enhanced error handling
-- `src/basic_memory/cli/commands/cloud/core_commands.py` - Updated login command to verify subscription access
-- `docs/cloud-cli.md` - Added Prerequisites and Subscription Issues sections
-
-**Files Created:**
-- `tests/cli/test_cloud_authentication.py` - Comprehensive test coverage (6 tests, all passing)
-
-**Key Implementation Details:**
-- `SubscriptionRequiredError` exception with `subscribe_url` field for user guidance
-- Enhanced `CloudAPIError` to include `status_code` and `detail` fields
-- Login flow now calls `/proxy/health` to verify subscription before enabling cloud mode
-- User-friendly error messages with direct subscribe link
-- 100% test coverage of new error handling paths
-
-**Test Results:**
-- All 6 tests passing
-- Type checking: 0 errors, 0 warnings
-- Linting: All checks passed
-
-**Next Steps:**
-- Phase 3: End-to-End Testing (manual testing with real users, subscription state transitions)
-- Phase 1: Complete remaining cloud service tests (unit tests, integration tests, deployment verification)

-### End-to-End Test Execution - 2025-10-03
-
-**Environment:**
-- Cloud Service: https://cloud.basicmemory.com
-- Cloud Service Version: Phase 1 deployed (with subscription validation)
-- CLI Version: Phase 2 implementation (local dev build)
-- Database: Production
-
-**Test Results:**
-
-#### Test 1: User Without Subscription ✅ PASSED
-- [x] OAuth flow succeeds
-- [x] Subscription error displayed
-- [x] Subscribe URL shown
-- [x] Cloud mode NOT enabled
-- [x] Clean error output (no traceback)
-
-**Output:**
-```
-✅ Successfully authenticated with WorkOS!
-Verifying subscription access...
-
-✗ Subscription Required
-
-Active subscription required
-
-Subscribe at: https://basicmemory.com/subscribe
-
-Once you have an active subscription, run bm cloud login again.
-```
-
-**Issues:** None
-
----
-
-#### Test 2: User With Active Subscription ✅ PASSED
-- [x] Login succeeds
-- [x] Cloud mode enabled
-- [x] Clean success message
-- [x] Ready for cloud operations
-
-**Output:**
-```
-✅ Successfully authenticated with WorkOS!
-Verifying subscription access...
-✓ Cloud mode enabled
-All CLI commands now work against https://cloud.basicmemory.com
-```
-
-**Issues:** None
-
----
-
-**Additional Implementation Notes:**
-
-**API Response Format Compatibility:**
-- Cloud service returns errors in FastAPI HTTPException format (nested under `"detail"` key)
-- CLI correctly handles both nested and flat response formats
-- Error parsing logic:
-  ```python
-  detail_obj = error_detail.get("detail", error_detail)
-  if isinstance(detail_obj, dict) and detail_obj.get("error") == "subscription_required":
-      # Handle subscription error
-  ```
-
-**Updated Test Coverage:**
-- Added `test_parse_subscription_required_error_flat_format()` for backward compatibility
-- Total: 6 tests, all passing
-- Files updated:
-  - `src/basic_memory/cli/commands/cloud/api_client.py` - Support both response formats
-  - `tests/cli/test_cloud_authentication.py` - Added flat format test
-
-**Overall Result:**
-- [x] Core authentication flows validated
-- [x] Error handling working as designed
-- [x] User experience is clean and helpful
-- [x] Ready for production use
-
-**Summary:**
-SPEC-13 Phase 2 successfully validated in production environment. Both unauthorized and authorized user flows work correctly. The subscription validation is functioning end-to-end with clear, user-friendly error messages and seamless success path. No issues discovered during testing.
-
-**Sign-off:** Phase 2 Complete - 2025-10-03

+# SPEC-14: Cloud Git Versioning & GitHub Backup
+
+**Status: DEFERRED** - Postponed until multi-user/teams feature development. Using S3 versioning (SPEC-9.1) for v1 instead.
+
+## Why Deferred
+
+**Original goals can be met with simpler solutions:**
+- Version history → **S3 bucket versioning** (automatic, zero config)
+- Offsite backup → **Tigris global replication** (built-in)
+- Restore capability → **S3 version restore** (`bm cloud restore --version-id`)
+- Collaboration → **Deferred to teams/multi-user feature** (not v1 requirement)
+
+**Complexity vs value trade-off:**
+- Git integration adds: committer service, puller service, webhooks, LFS, merge conflicts
+- Risk: Loop detection between Git ↔ rclone bisync ↔ local edits
+- S3 versioning gives 80% of value with 5% of complexity
+
+**When to revisit:**
+- Teams/multi-user features (PR-based collaboration workflow)
+- User requests for commit messages and branch-based workflows
+- Need for fine-grained audit trail beyond S3 object metadata
+
+---
+
+## Original Specification (for reference)
+
+## Why
+Early access users want **transparent version history**, easy **offsite backup**, and a familiar **restore/branching** workflow. Git/GitHub integration would provide:
+- Auditable history of every change (who/when/why)
+- Branches/PRs for review and collaboration
+- Offsite private backup under the user's control
+- Escape hatch: users can always `git clone` their knowledge base
+
+**Note:** These goals are now addressed via S3 versioning (SPEC-9.1) for single-user use case.
+
+## Goals
+- **Transparent**: Users keep using Basic Memory; Git runs behind the scenes.
+- **Private**: Push to a **private GitHub repo** that the user owns (or tenant org).
+- **Reliable**: No data loss, deterministic mapping of filesystem ↔ Git.
+- **Composable**: Plays nicely with SPEC‑9 bisync and upcoming conflict features (SPEC‑9 Follow‑Ups).
+
+**Non‑Goals (for v1):**
+- Fine‑grained per‑file encryption in Git history (can be layered later).
+- Large media optimization beyond Git LFS defaults.
+
+## User Stories
+1. *As a user*, I connect my GitHub and choose a private backup repo.
+2. *As a user*, every change I make in cloud (or via bisync) is **committed** and **pushed** automatically.
+3. *As a user*, I can **restore** a file/folder/project to a prior version.
+4. *As a power user*, I can **git pull/push** directly to collaborate outside the app.
+5. *As an admin*, I can enforce repo ownership (tenant org) and least‑privilege scopes.
+
+## Scope
+- **In scope:** Full repo backup of `/app/data/` (all projects) with optional selective subpaths.
+- **Out of scope (v1):** Partial shallow mirrors; encrypted Git; cross‑provider SCM (GitLab/Bitbucket).
+
+## Architecture
+### Topology
+- **Authoritative working tree**: `/app/data/` (bucket mount) remains the source of truth (SPEC‑9).
+- **Bare repo** lives alongside: `/app/git/${tenant}/knowledge.git` (server‑side).
+- **Mirror remote**: `github.com/<owner>/<repo>.git` (private).
+
+```mermaid
+flowchart LR
+  A[/Users & Agents/] -->|writes/edits| B[/app/data/]
+  B -->|file events| C[Committer Service]
+  C -->|git commit| D[(Bare Repo)]
+  D -->|push| E[(GitHub Private Repo)]
+  E -->|webhook (push)| F[Puller Service]
+  F -->|git pull/merge| D
+  D -->|checkout/merge| B
+```
+
+### Services
+- **Committer Service** (daemon):
+  - Watches `/app/data/` for changes (inotify/poll)
+  - Batches changes (debounce e.g. 2–5s)
+  - Writes `.bmmeta` (if present) into commit message trailer (see Follow‑Ups)
+  - `git add -A && git commit -m "chore(sync): <summary>
+
+BM-Meta: <json>"`
+  - Periodic `git push` to GitHub mirror (configurable interval)
+- **Puller Service** (webhook target):
+  - Receives GitHub webhook (push) → `git fetch`
+  - **Fast‑forward** merges to `main` only; reject non‑FF unless policy allows
+  - Applies changes back to `/app/data/` via clean checkout
+  - Emits sync events for Basic Memory indexers
+
+### Auth & Security
+- **GitHub App** (recommended): minimal scopes: `contents:read/write`, `metadata:read`, webhook.
+- Tenant‑scoped installation; repo created in user account or tenant org.
+- Tokens stored in KMS/secret manager; rotated automatically.
+- Optional policy: allow only **FF merges** on `main`; non‑FF requires PR.
+
+### Repo Layout
+- **Monorepo** (default): one repo per tenant mirrors `/app/data/` with subfolders per project.
+- Optional multi‑repo mode (later): one repo per project.
+
+### File Handling
+- Honor `.gitignore` generated from `.bmignore.rclone` + BM defaults (cache, temp, state).
+- **Git LFS** for large binaries (images, media) — auto track by extension/size threshold.
+- Normalize newline + Unicode (aligns with Follow‑Ups).
+
+### Conflict Model
+- **Primary concurrency**: SPEC‑9 Follow‑Ups (`.bmmeta`, conflict copies) stays the first line of defense.
+- **Git merges** are a **secondary** mechanism:
+  - Server only auto‑merges **text** conflicts when trivial (FF or clean 3‑way).
+  - Otherwise, create `name (conflict from <branch>, <ts>).md` and surface via events.
+
+### Data Flow vs Bisync
+- Bisync (rclone) continues between local sync dir ↔ bucket.
+- Git sits **cloud‑side** between bucket and GitHub.
+- On **pull** from GitHub → files written to `/app/data/` → picked up by indexers & eventually by bisync back to users.
+
+## CLI & UX
+New commands (cloud mode):
+- `bm cloud git connect` — Launch GitHub App installation; create private repo; store installation id.
+- `bm cloud git status` — Show connected repo, last push time, last webhook delivery, pending commits.
+- `bm cloud git push` — Manual push (rarely needed).
+- `bm cloud git pull` — Manual pull/FF (admin only by default).
+- `bm cloud snapshot -m "message"` — Create a tagged point‑in‑time snapshot (git tag).
+- `bm restore <path> --to <commit|tag>` — Restore file/folder/project to prior version.
+
+Settings:
+- `bm config set git.autoPushInterval=5s`
+- `bm config set git.lfs.sizeThreshold=10MB`
+- `bm config set git.allowNonFF=false`
+
+## Migration & Backfill
+- On connect, if repo empty: initial commit of entire `/app/data/`.
+- If repo has content: require **one‑time import** path (clone to staging, reconcile, choose direction).
+
+## Edge Cases
+- Massive deletes: gated by SPEC‑9 `max_delete` **and** Git pre‑push hook checks.
+- Case changes and rename detection: rely on git rename heuristics + Follow‑Ups move hints.
+- Secrets: default ignore common secret patterns; allow custom deny list.
+
+## Telemetry & Observability
+- Emit `git_commit`, `git_push`, `git_pull`, `git_conflict` events with correlation IDs.
+- `bm sync --report` extended with Git stats (commit count, delta bytes, push latency).
+
+## Phased Plan
+### Phase 0 — Prototype (1 sprint)
+- Server: bare repo init + simple committer (batch every 10s) + manual GitHub token.
+- CLI: `bm cloud git connect --token <PAT>` (dev‑only)
+- Success: edits in `/app/data/` appear in GitHub within 30s.
+
+### Phase 1 — GitHub App & Webhooks (1–2 sprints)
+- Switch to GitHub App installs; create private repo; store installation id.
+- Committer hardened (debounce 2–5s, backoff, retries).
+- Puller service with webhook → FF merge → checkout to `/app/data/`.
+- LFS auto‑track + `.gitignore` generation.
+- CLI surfaces status + logs.
+
+### Phase 2 — Restore & Snapshots (1 sprint)
+- `bm restore` for file/folder/project with dry‑run.
+- `bm cloud snapshot` tags + list/inspect.
+- Policy: PR‑only non‑FF, admin override.
+
+### Phase 3 — Selective & Multi‑Repo (nice‑to‑have)
+- Include/exclude projects; optional per‑project repos.
+- Advanced policies (branch protections, required reviews).
+
+## Acceptance Criteria
+- Changes to `/app/data/` are committed and pushed automatically within configurable interval (default ≤5s).
+- GitHub webhook pull results in updated files in `/app/data/` (FF‑only by default).
+- LFS configured and functioning; large files don't bloat history.
+- `bm cloud git status` shows connected repo and last push/pull times.
+- `bm restore` restores a file/folder to a prior commit with a clear audit trail.
+- End‑to‑end works alongside SPEC‑9 bisync without loops or data loss.
+
+## Risks & Mitigations
+- **Loop risk (Git ↔ Bisync)**: Writes to `/app/data/` → bisync → local → user edits → back again. *Mitigation*: Debounce, commit squashing, idempotent `.bmmeta` versioning, and watch exclusion windows during pull.
+- **Repo bloat**: Lots of binary churn. *Mitigation*: default LFS, size threshold, optional media‑only repo later.
+- **Security**: Token leakage. *Mitigation*: GitHub App with short‑lived tokens, KMS storage, scoped permissions.
+- **Merge complexity**: Non‑trivial conflicts. *Mitigation*: prefer FF; otherwise conflict copies + events; require PR for non‑FF.
+
+## Open Questions
+- Do we default to **monorepo** per tenant, or offer project‑per‑repo at connect time?
+- Should `restore` write to a branch and open a PR, or directly modify `main`?
+- How do we expose Git history in UI (timeline view) without users dropping to CLI?

+
+**Important:** No URL prefix stripping needed. The transport receives relative URLs like `/main/resource/notes/my-note` which are correctly routed to tenant APIs. The `/proxy` prefix only exists for web UI requests to the proxy router, not for MCP tools using the custom transport.

+# SPEC-4: Notes Web UI Component Architecture
+
+## Why
+
+The current Notes.vue component is a monolithic component that handles multiple responsibilities, making it difficult to maintain, test, and understand. This leads to:
+
+- Complex state management across multiple concerns
+- Difficult to isolate and test individual features
+- Hard to understand the full scope of functionality
+- Circular refactoring cycles when making changes
+- Poor separation of concerns between navigation, display, and interaction logic
+
+We need to decompose this into focused, single-responsibility components that are easier to develop, test, and maintain while preserving the existing functionality users expect.
+
+## What
+
+This spec defines the component architecture for decomposing the Notes web UI into focused components with clear responsibilities and interactions.
+
+**Affected Areas:**
+- `/apps/web/components/notes/Notes.vue` - Will be decomposed into smaller components
+- `/apps/web/components/notes/` - New component structure 
+- Existing composables: `useNotesNavigation`, `useNotesFiltering`, `useNotesLayout`
+- Mobile responsive behavior and layout management
+
+**Component Breakdown:**

+
+
+### ProjectSwitcher Component
+- **Location**: Top-left dropdown
+- **Responsibility**: Allow users to switch between Basic Memory projects
+- **Behavior**: Selecting different project controls entire Notes page content
+- **State**: When switching projects, reset to "All notes" view
+
+### NotesNav Component  
+- **Views**: Three mutually exclusive options:
+  - **All notes**: Display all notes in project alphabetically
+  - **Recent**: Display all notes in project by updated time (desc)
+  - **Project**: Display notes in top-level directory of project
+- **Interaction**: Only one view can be active at a time
+- **Folder Integration**: All/Recent ignore folder selection; Project respects folder selection
+
+### FolderTree Component
+- **Display**: Nested list of all folders in project as tree view
+- **Interaction**: Selecting folder filters notes in NotesList using directoryList API
+- **Navigation Integration**: Selecting folder automatically switches NotesNav to "Project" view for clear UX
+- **API Integration**: Uses directoryList API call via useDirectoryListQuery for folder-specific note fetching
+- **State Coordination**: Folder selection coordinates with navigation state for intuitive user experience
+
+### NotesList Component
+- **Display**: Vertically scrolling cards showing note summaries
+- **Information per card**:
+  - Note title
+  - Modified time (relative, e.g., "7 minutes ago")  
+  - Short summary of note content (one line preview)
+- **Behavior**: Updates based on NotesNav selection and FolderTree filtering
+
+### NoteDetail Component
+- **Display**: Full content of selected note
+- **Sections**:
+  - Header: Displays frontmatter information
+  - Content: Note body content
+- **Editing**: Current textarea implementation (rich editor in future spec)
+- **Frontmatter**: Leave current implementation (enhancement in future spec)
+
+## How (High Level)
+
+### Component Architecture Approach
+1. **Single Responsibility**: Each component handles one primary concern
+2. **Clear Data Flow**: Props down, events up pattern for component communication
+3. **Composable Integration**: Use existing composables for state management
+4. **Progressive Decomposition**: Extract components incrementally to maintain functionality
+
+### Implementation Strategy
+1. **Extract ProjectSwitcher**: Move project switching logic to dedicated component
+2. **Extract NotesNav**: Isolate navigation state and view selection logic
+3. **Extract FolderTree**: Separate folder display and selection logic
+4. **Extract NotesList**: Isolate note listing and card display logic  
+5. **Extract NoteDetail**: Separate note content display and editing
+6. **Update Notes.vue**: Become orchestration component managing component interactions
+
+### State Management Integration
+- **useNotesNavigation**: Manages navigation state (All/Recent/Project)
+- **useNotesFiltering**: Handles filtering logic based on navigation and folder selection
+- **useNotesLayout**: Manages responsive layout and panel visibility
+- **Component State**: Each component manages its own internal UI state
+- **Shared State**: Project selection and note filtering coordinated through composables
+
+### Responsive Behavior
+
+Mobile:
+- Hide sidebar. pop out panel when selected 
+- show note list on small screens (existing behavior)
+- when note list item is clicked, display note detail on full page. Cancel or go back to return to list
+
+Desktop: 
+- Full three-column layout with all components visible
+
+- **Transitions**: Smooth navigation between mobile panels
+
+## How to Evaluate
+
+### Success Criteria
+- **Functional Parity**: All existing Notes page functionality preserved
+- **Component Isolation**: Each component can be developed/tested independently  
+- **Clear Responsibilities**: No overlapping concerns between components
+- **State Clarity**: Clean data flow and state management patterns
+- **Mobile Compatibility**: Responsive behavior maintains current UX
+- **Performance**: No degradation in rendering or interaction performance
+
+### Testing Procedure
+1. **Functionality Validation**:
+   - Project switching works correctly
+   - All three navigation views (All/Recent/Project) function properly
+   - Folder selection affects note display appropriately
+   - Note selection and detail display works
+   - Mobile responsive behavior preserved
+
+2. **Component Isolation Testing**:
+   - Each component can be imported and used independently
+   - Component props and events are clearly defined
+   - No tight coupling between components
+
+3. **Integration Testing**:
+   - Components communicate correctly through props/events
+   - State management composables integrate properly
+   - User workflows function end-to-end
+
+4. **Performance Validation**:
+   - Page load time unchanged or improved
+   - Interaction responsiveness maintained
+   - Memory usage stable or improved
+
+### Implementation Validation
+- **Code Review**: Clean component structure with single responsibilities
+- **Type Safety**: Full TypeScript coverage with proper component prop types
+- **Documentation**: Each component has clear interface documentation
+- **Tests**: Unit tests for individual components and integration tests for workflows
+
+## Observations
+
+- [problem] Monolithic Notes.vue component creates maintenance and testing challenges #component-architecture
+- [solution] Component decomposition improves separation of concerns and testability #refactoring
+- [pattern] Progressive extraction maintains functionality while improving structure #incremental-improvement
+- [interaction] NotesNav and FolderTree have conditional interaction based on selected view #state-management
+- [constraint] Mobile responsive behavior must be preserved during decomposition #responsive-design
+- [scope] Current editing and frontmatter capabilities remain unchanged #scope-limitation
+- [validation] Functional parity is critical success criteria for this refactoring #validation-strategy
+- [implementation] Folder selection now properly integrates with directoryList API for accurate filtering #api-integration
+- [fix] FolderTree selection functionality completed - works across all navigation views #feature-complete
+- [ux-improvement] FolderTree selection automatically switches NotesNav to Project view for clear user feedback #user-experience

+## Implementation Progress
+
+### Components
+
+1. **ProjectSwitcher** (`~/components/notes/ProjectSwitcher.vue`)
+   - ✅ Top-left dropdown for project switching
+   - ✅ Integrates with Pinia project store
+   - ✅ Handles project switching with proper state reset
+   - ✅ Responsive collapsed/expanded states
+   - ✅ Expanded menu shows available projects and a Manage Projects option that navigates to the /settings/projects page
+   - ✅ Simplified component following SortingToggle pattern - clean Props/Emits interface, uses ProjectItem type directly 
+
+2. **NotesNav** (`~/components/notes/NotesNav.vue`)
+   - ✅ Three mutually exclusive views: All/Recent/Project
+   - ✅ Dynamic project title based on selected project
+   - ✅ Clean props down, events up pattern
+   - ✅ Responsive collapsed/expanded states with tooltips
+   - ✅ The label for the Project selection should be the folder name for the project, not the project name
+
+3. **FolderTree** (`~/components/notes/FolderTree.vue`)
+   - ✅ Nested folder tree view for filtering
+   - ✅ Uses `useFolderTree()` composable for data
+   - ✅ Emits `folder-selected` events properly
+   - ✅ Handles loading, error, and empty states
+   - ✅ Includes companion `FolderTreeNode.vue` component
+   - ✅ The current folder should be visibly selected in the tree

 ## Why
 
 Current basic-memory-cloud architecture uses Fly volumes for tenant file storage, which creates several limitations:
 
-1. **Storage Scalability**: Fly volumes require pre-provisioning and don't auto-scale with usage
-2. **Cost Model**: Volume pricing vs object storage pricing may be less favorable at scale
-3. **Local Development**: No way for users to mount their cloud tenant files locally for real-time editing
-4. **Multi-Region**: Volumes are region-locked, limiting global deployment flexibility
-5. **Backup/Disaster Recovery**: Object storage provides better durability and replication options
+We could enable a revolutionary user experience: **local editing (or at least view access) of cloud-stored files** while maintaining Basic Memory's existing filesystem assumptions.
 
-The core insight is that Basic Memory requires POSIX filesystem semantics but could benefit from object storage durability and accessibility. By combining:
-- **Tigris object storage** for file persistence (via rclone mount)
-- **Turso/libSQL** for SQLite indexing (replacing local .db files)

+## Architectural Overview & Key Insights
+
+### TigrisFS
+
+Unlike standard S3 mounting approaches, **TigrisFS is a purpose-built FUSE filesystem** optimized for object storage with several critical advantages:
+
+1. **Eliminates Fly Volume Limitations**
+   - No single-machine attachment constraints
+   - No pre-provisioning of storage capacity
+   - Enables horizontal scaling and zero-downtime deployments
+   - Automatic global CDN caching at Fly.io edge locations
+
+2. **Intelligent Caching Architecture**
+   - 1-4GB+ configurable memory cache for read/write operations
+   - Write-back caching for improved performance
+   - Metadata cache to reduce API calls
+   - "Close to Redis speed" for small object retrieval
+
+3. **Cost-Effective Model**
+   - Pay only for storage used and transferred
+   - No wasted capacity from over-provisioning
+   - Automatic global replication included
+   - S3 durability with CDN performance
+
+### API-Driven Architecture Eliminates File Watching Concerns
+
+**Critical Insight**: All file access (reads/writes) in basic-memory-cloud go through the API layer:
+- **MCP Tools → API**: All Basic Memory operations use FastAPI endpoints
+- **Web App → API**: Frontend uses API for all data modifications
+- **File watching is NOT required** for cloud operations, unlike local BM which uses the WatchService to monitor file changes.
+
+This means:
+- **Cloud Operations**: Manual sync after API writes is sufficient
+- **Local Development**: File watching only matters for local editing experience
+- **Performance Risk**: Dramatically reduced since we're not dependent on inotify over network filesystems
+
+### Realistic Local Access Expectations
+
+**Baseline Functionality (Guaranteed):**
+- Read-only mounting for browsing cloud files
+- Easy download/upload of entire projects
+- File copying via standard filesystem operations
+
+**Stretch Goal (Test in POC):**
+- Live editing with eventual consistency (1-5 second delays acceptable)
+- Automatic sync for local changes
+- Not required for core functionality - pure upside if it works
+
+### Production Deployment Advantages
+
+1. **Multi-Region Deployment**: Tigris handles global replication automatically
+2. **Zero-Downtime Updates**: No volume detach/attach during deployments
+3. **Tenant Migrations**: Simply update credentials, no data movement
+4. **Disaster Recovery**: Built into S3 durability model (99.999999999% durability)
+5. **Auto-Scaling**: Storage scales with usage, no capacity planning needed
+
+
 ## How (High Level)
 
-### Phase 1: Local POC Validation
-- [ ] Set up Tigris bucket with test data
-- [ ] Configure rclone NFS mount locally
-- [ ] Test Basic Memory operations over mounted filesystem
-- [ ] Measure performance characteristics and identify issues
-- [ ] Validate file watching, sync operations, and concurrent access patterns
+### POC Approach: Server-First Validation
 
-### Phase 2: Database Migration
+**Rationale**: Start with server-side TigrisFS mounting because:
+- Local access is meaningless if cloud containers can't mount TigrisFS reliably
+- Container startup and API performance are critical path blockers
+- TigrisFS compatibility with Basic Memory operations must be proven first
+- Each phase gates the next - no point testing local access if server-side fails

 ### Testing Procedure
-1. **Local Filesystem Test**:
-   ```bash
-   # Mount Tigris bucket locally
-   rclone nfsmount tigris:test-bucket ~/tigris-test --vfs-cache-mode writes
 
-   # Run Basic Memory operations
-   cd ~/tigris-test && basic-memory sync --watch
-   # Test: create notes, search, file watching, bulk operations
+#### Phase 1: Server-Side Foundation Testing
+1. **Container TigrisFS Test**:
+   ```dockerfile
+   # Test container with TigrisFS mounting
+   FROM python:3.12
+   RUN apt-get update && apt-get install -y tigrisfs
+
+   # Test startup script
+   #!/bin/bash
+   tigrisfs --memory-limit 2048 $TIGRIS_BUCKET /app/data --daemon
+   cd /app/data && basic-memory sync
+   basic-memory-api --data-dir /app/data
    ```
 
-2. **Database Migration Test**:
+2. **API Operations Validation**:
    ```bash
-   # Configure Turso connection
+   # Test all MCP operations over TigrisFS
+   curl -X POST /api/write_note -d '{"title":"test","content":"content"}'
+   curl -X GET /api/read_note/test
+   curl -X GET /api/search_notes?q=content
+   # Measure: response times, error rates, data consistency
+   ```
+
+#### Phase 2: Database Integration Testing
+3. **Turso Integration Test**:
+   ```bash
+   # Configure Turso connection in container
    export DATABASE_URL="libsql://test-db.turso.io?authToken=..."
 
    # Test all MCP tools with remote database
    basic-memory tools # Test each tool functionality
+   # Test API write → manual sync workflow
    ```
 
-3. **Container Integration Test**:
-   ```dockerfile
-   # Test container with rclone mounting
-   FROM python:3.12
-   RUN apt-get update && apt-get install -y rclone nfs-common
-   # ... test startup and mounting process
+#### Phase 3: Production Readiness Testing
+4. **Performance Benchmarking**:
+   - Container startup time with TigrisFS mounting
+   - API operation response times (target: <500ms for typical operations)
+   - Search query performance with Turso (target: comparable to local SQLite)
+   - TigrisFS cache hit rates and memory usage
+   - Concurrent tenant isolation
+
+#### Phase 4: Local Access Testing (If Phase 1-3 Succeed)
+5. **Local Access Validation**:
+   ```bash
+   # Test read-only access
+   tigrisfs tenant-bucket ~/local-tenant
+   ls -la ~/local-tenant  # Browse files
+   cp ~/local-tenant/notes/* ~/backup/  # Copy files
+
+   # Test file watching (stretch goal)
+   echo "test" > ~/local-tenant/test.md
+   # Check if changes sync to cloud
    ```
 
-4. **Performance Benchmarking**:
-   - File creation/read/write operations (target: <2x local latency)
-   - Search query performance (target: comparable to local SQLite)
-   - File watching responsiveness (target: events within 1-2 seconds)
-   - Concurrent operation handling
+### Go/No-Go Criteria by Phase
+- **Phase 1**: Container must start successfully and serve API requests over TigrisFS
+- **Phase 2**: All MCP tools must work with Turso with <2x latency increase
+- **Phase 3**: Performance must be within 50% of current Fly volume setup
+- **Phase 4**: Local mounting must work reliably for read-only access
 
 ### Risk Assessment
-**High Risk Items**:
-- [ ] NFS-over-S3 performance may be insufficient for real-time operations
-- [ ] File watching (`inotify`) over NFS may be unreliable
-- [ ] Network interruptions could cause filesystem errors
-- [ ] Concurrent access patterns might hit S3 rate limits
+**Moderate Risk Items (Mitigated by API-First Architecture)**:
+- [ ] TigrisFS performance for local access may have higher latency than local filesystem
+- [ ] File watching (`inotify`) over FUSE may be unreliable for local development
+- [ ] Network interruptions could cause filesystem errors during local editing
+- [ ] Write-back caching could cause data loss if container crashes during flush
+
+**Low Risk Items (API-First Eliminates)**:
+- [ ] ~~Real-time file watching~~ - Not required for cloud operations
+- [ ] ~~Concurrent write consistency~~ - Single-tenant model with API coordination
+- [ ] ~~S3 rate limits~~ - TigrisFS intelligent caching handles this
 
 **Mitigation Strategies**:
-- Comprehensive performance testing before committing to architecture
-- Fallback plan to S3-native storage backend if filesystem approach fails
-- Extensive error handling and retry logic for network issues
+- **Performance**: Comprehensive benchmarking with realistic workloads
+- **Reliability**: Graceful degradation to read-only local access if live editing fails
+- **Data Safety**: Regular sync intervals and write-through mode for critical operations
+- **Fallback**: Keep Fly volumes as backup deployment option
 
 ### Metrics to Track
-- **Latency**: File operation response times (read/write/watch)
-- **Reliability**: Success rate of file operations over time
-- **Throughput**: Concurrent file operations and search queries
-- **User Experience**: Perceived performance for local mounting use case
+- **API Latency**: Response times for MCP tools and web operations
+- **Cache Effectiveness**: TigrisFS cache hit rates and memory usage
+- **Local Access Performance**: File browsing and copying speeds
+- **Reliability**: Success rate of mount operations and data consistency
+- **Cost**: Storage usage, API calls, and network transfer costs vs current volumes
 
 ## Notes
 
 ### Key Architectural Decisions
 - **Single tenant per bucket/database**: Simplifies isolation and credential management
 - **Maintain POSIX compatibility**: Preserve Basic Memory's existing filesystem assumptions
-- **NFS over FUSE**: Better compatibility and performance characteristics
+- **TigrisFS over rclone**: Purpose-built for object storage with intelligent caching
 - **Turso for SQLite**: Leverages specialized remote SQLite expertise
+- **API-first approach**: Eliminates file watching dependency for cloud operations
 
 ### Alternative Approaches Considered
 - **S3-native storage backend**: Would require Basic Memory architecture changes
 - **Hybrid approach**: Local files + cloud sync (adds complexity)
-- **FUSE mounting**: More platform dependencies and kernel requirements
+- **Standard rclone mounting**: Less optimized than TigrisFS for object storage workloads
+- **Keep Fly volumes**: Maintains current limitations but proven reliability
 
 ### Integration Points
 - [ ] Fly.io Tigris integration for bucket provisioning
 - [ ] Turso account setup and database provisioning
-- [ ] Container image modifications for rclone support
+- [ ] Container image modifications for TigrisFS support
 - [ ] Credential management for tenant isolation
+- [ ] API modification for manual sync triggers
+- [ ] Local client setup documentation for TigrisFS mounting
 
 ## Observations
 
 - [architecture] Tigris/Turso split cleanly separates file storage from indexing concerns #storage-separation
+- [breakthrough] API-first architecture eliminates file watching dependency for cloud operations #api-first-advantage
 - [user-experience] Local mounting of cloud files could be revolutionary for knowledge management #local-cloud-hybrid
 - [compatibility] Maintaining POSIX filesystem assumptions preserves Basic Memory's local/cloud compatibility #architecture-preservation
 - [simplification] Single tenant per bucket eliminates complex multi-tenancy in storage layer #tenant-isolation
-- [risk] NFS-over-S3 performance characteristics are unproven for real-time operations #performance-risk
+- [performance] TigrisFS intelligent caching could provide near-local performance for common operations #tigrisfs-advantage
+- [deployment] Zero-downtime updates become trivial without volume constraints #deployment-simplification
 - [benefit] Object storage pricing model could be more favorable than volume pricing #cost-optimization
-- [innovation] Real-time local editing of cloud-stored files addresses major SaaS limitation #competitive-advantage
+- [innovation] Read-only local access alone would address major SaaS limitation #competitive-advantage
+- [risk-mitigation] API-driven sync reduces performance requirements vs real-time file watching #risk-reduction

+
+# SPEC-9: Signed Header Tenant Information
+
+## Why
+
+WorkOS JWT templates don't work with MCP's dynamic client registration requirement, preventing us from getting tenant information directly in JWT tokens. We need an alternative secure method to pass tenant context from the Cloud Proxy Service to tenant instances.
+
+**Problem Context:**
+- MCP spec requires dynamic client registration
+- WorkOS JWT templates only apply to statically configured clients
+- Without tenant information, we can't properly route requests or isolate tenant data
+- Current JWT tokens only contain standard OIDC claims (sub, email, etc.)
+
+**Affected Areas:**
+- Cloud Proxy Service (`apps/cloud`) - request forwarding
+- Tenant API instances (`apps/api`) - tenant context validation
+- MCP Gateway (`apps/mcp`) - authentication flow
+- Overall tenant isolation security model
+
+## What
+
+Implement HMAC-signed headers that the Cloud Proxy Service adds when forwarding requests to tenant instances. This provides secure, tamper-proof tenant information without relying on JWT custom claims.
+
+**Components:**
+- Header signing utility in Cloud Proxy Service
+- Header validation middleware in Tenant API instances
+- Shared secret configuration across services
+- Fallback mechanisms for development and error cases
+
+## How (High Level)
+
+### 1. Header Format
+Add these signed headers to all proxied requests:
+```
+X-BM-Tenant-ID: {tenant_id}
+X-BM-Timestamp: {unix_timestamp}
+X-BM-Signature: {hmac_sha256_signature}
+```
+
+### 2. Signature Algorithm
+```python
+# Canonical message format
+message = f"{tenant_id}:{timestamp}"
+
+# HMAC-SHA256 signature
+signature = hmac.new(
+    key=shared_secret.encode('utf-8'),
+    msg=message.encode('utf-8'),
+    digestmod=hashlib.sha256
+).hexdigest()
+```
+
+### 3. Implementation Flow
+
+#### Cloud Proxy Service (`apps/cloud`)
+1. Extract `tenant_id` from authenticated user profile
+2. Generate timestamp and canonical message
+3. Sign message with shared secret
+4. Add headers to request before forwarding to tenant instance
+
+#### Tenant API Instances (`apps/api`)
+1. Middleware validates headers on all incoming requests
+2. Extract tenant_id, timestamp from headers
+3. Verify timestamp is within acceptable window (5 minutes)
+4. Recompute signature and compare in constant time
+5. If valid, make tenant context available to Basic Memory tools
+
+### 4. Security Properties
+- **Authenticity**: Only services with shared secret can create valid signatures
+- **Integrity**: Header tampering invalidates signature
+- **Replay Protection**: Timestamp prevents reuse of old signatures
+- **Non-repudiation**: Each request is cryptographically tied to specific tenant
+
+### 5. Configuration
+```bash
+# Shared across Cloud Proxy and Tenant instances
+BM_TENANT_HEADER_SECRET=randomly-generated-256-bit-secret
+
+# Tenant API configuration
+BM_TENANT_HEADER_VALIDATION=true  # true (production) | false (dev only)
+```
+
+## How to Evaluate
+
+### Unit Tests
+- [ ] Header signing utility generates correct signatures
+- [ ] Header validation correctly accepts/rejects signatures
+- [ ] Timestamp validation within acceptable windows
+- [ ] Constant-time signature comparison prevents timing attacks
+
+### Integration Tests
+- [ ] End-to-end request flow from MCP client → proxy → tenant
+- [ ] Tenant isolation verified with signed headers
+- [ ] Error handling for missing/invalid headers
+- [ ] Disabled validation in development environment
+
+### Security Validation
+- [ ] Shared secret rotation procedure
+- [ ] Header tampering detection
+- [ ] Clock skew tolerance testing
+- [ ] Performance impact measurement
+
+### Production Readiness
+- [ ] Logging and monitoring of header validation
+- [ ] Graceful degradation for header validation failures
+- [ ] Documentation for secret management
+- [ ] Deployment configuration templates
+
+## Implementation Notes
+
+### Shared Secret Management
+- Generate cryptographically secure 256-bit secret
+- Same secret deployed to Cloud Proxy and all Tenant instances
+- Consider secret rotation strategy for production
+
+### Error Handling
+```python
+# Strict mode (production)
+if not validate_headers(request):
+    raise HTTPException(status_code=401, detail="Invalid tenant headers")
+
+# Fallback mode (development)
+if not validate_headers(request):
+    logger.warning("Invalid headers, falling back to default tenant")
+    tenant_id = "default"
+```
+
+### Performance Considerations
+- HMAC-SHA256 computation is fast (~microseconds)
+- Headers add ~200 bytes to each request
+- Validation happens once per request in middleware
+
+## Benefits
+
+✅ **Works with MCP dynamic client registration** - No dependency on JWT custom claims
+✅ **Simple and reliable** - Standard HMAC signature approach
+✅ **Secure by design** - Cryptographic authenticity and integrity
+✅ **Infrastructure controlled** - No external service dependencies
+✅ **Easy to implement** - Clear signature algorithm and validation
+
+## Trade-offs
+
+⚠️ **Shared secret management** - Need secure distribution and rotation
+⚠️ **Clock synchronization** - Timestamp validation requires reasonably synced clocks
+⚠️ **Header visibility** - Headers visible in logs (tenant_id not sensitive)
+⚠️ **Additional complexity** - More moving parts in proxy forwarding
+
+## Implementation Tasks
+
+### Cloud Service (Header Signing)
+- [ ] Create `utils/header_signing.py` with HMAC-SHA256 signing function
+- [ ] Add `bm_tenant_header_secret` to Cloud service configuration
+- [ ] Update `ProxyService.forward_request()` to call signing utility
+- [ ] Add signed headers (X-BM-Tenant-ID, X-BM-Timestamp, X-BM-Signature)
+
+### Tenant API (Header Validation)
+- [ ] Create `utils/header_validation.py` with signature verification
+- [ ] Add `bm_tenant_header_secret` to API service configuration
+- [ ] Create `TenantHeaderValidationMiddleware` class
+- [ ] Add middleware to FastAPI app (before other middleware)
+- [ ] Skip validation for `/health` endpoint
+- [ ] Store validated tenant_id in request.state
+
+### Testing
+- [ ] Unit test for header signing utility
+- [ ] Unit test for header validation utility
+- [ ] Integration test for proxy → tenant flow
+- [ ] Test invalid/missing header handling
+- [ ] Test timestamp window validation
+- [ ] Test signature tampering detection
+
+### Configuration & Deployment
+- [ ] Update `.env.example` with BM_TENANT_HEADER_SECRET
+- [ ] Generate secure 256-bit secret for production
+- [ ] Update Fly.io secrets for both services
+- [ ] Document secret rotation procedure
+
+## Status
+
+- [x] **Specification Complete** - Design finalized and documented
+- [ ] **Implementation Started** - Header signing utility development
+- [ ] **Cloud Proxy Updated** - ProxyService adds signed headers
+- [ ] **Tenant Validation Added** - Middleware validates headers
+- [ ] **Testing Complete** - All validation criteria met
+- [ ] **Production Deployed** - Live with tenant isolation via headers
