It is a dedicated, predictable place to provide the context and instructions to help AI coding agents work on LightRAG project. Different AI coders should not maintain separate guidance files individually. If any AI coder cannot automatically recognize AGENTS.md, symbolic links can be used as a solution. After establishing symbolic links, you can prevent them from being committed to the Git repository by configuring your local `.gitignore_global`. diff --git a/docs/MULTI_TENANT_STORAGE_AUDIT.md b/docs/MULTI_TENANT_STORAGE_AUDIT.md new file mode 100644 index 00000000..131346a1 --- /dev/null +++ b/docs/MULTI_TENANT_STORAGE_AUDIT.md @@ -0,0 +1,192 @@ +# Multi-Tenant Storage Backend Audit Report + +**Date:** 2025-01-20 +**Auditor:** GitHub Copilot +**Branch:** `premerge/integration-upstream` +**Test Results:** 134 passed, 2 skipped + +--- + +## Executive Summary + +All 19 storage backend implementations in LightRAG correctly implement multi-tenant isolation using the `workspace` parameter.
