# Task Log - Multi-Tenant Audit Session

**Date:** 2025-11-29
**Mode:** Beastmode

---

## Actions

- Explored codebase structure for multi-tenant implementation components
- Read and analyzed key files: `dependencies.py`, `tenant_rag_manager.py`, `postgres_impl.py`, `tenant.ts`
- Created audit documentation structure in `docs/action_plan/multitenant-audit/`
- Updated existing audit documents with detailed findings
- Started Docker test containers (PostgreSQL on 5433, Redis on 6380)
- Executed 102 unit tests across 4 test suites - all passed
- Created API isolation test script for manual testing
- Compiled final audit report with security findings and recommendations

## Decisions

- Used workspace-based isolation model understanding (`workspace = tenant_id/kb_id`)
- Identified 6 security findings with severity ratings
- Focused on code review + unit tests rather than integration tests due to import issues
- Documented both strengths and concerns of the implementation

## Next Steps

1. Fix import issues in `test_document_routes_tenant_scoped.py` and `test_tenant_api_routes.py`
2. Start API server and run `test_api_isolation.py` script for live testing
3. Address HIGH priority security findings (SEC-001, SEC-002)
4. Consider enabling PostgreSQL RLS for defense-in-depth

## Lessons/Insights

- Multi-tenant implementation is functionally correct at unit test level
- Critical security gap: `get_tenant_context_optional` allows global RAG fallback
- Admin user bypass in `tenant_service.py` is marked "temporary" but still present
- No database-level RLS - all isolation relies on application code
- 102/102 unit tests pass, demonstrating solid foundational implementation
