Here is the representation change, regression evidence and migration boundary in a merged AI-Infra-Guard contribution.https://leon-ai-workflows.pages.dev/engineering/mcp-empty-discoveryhttps://leon-ai-workflows.pages.dev/engineering/mcp-empty-discoveryAn empty OAuth discovery result should not erase a saved catalog. This merged contribution preserves entries and checks retained aliases within their actual visibility scope.https://leon-ai-workflows.pages.dev/engineering/git-scan-inventoryhttps://leon-ai-workflows.pages.dev/engineering/git-scan-inventoryNested repositories, linked worktrees and scopes inside .git need explicit inventory boundaries. A merged contribution and the regressions behind it.
