 - Data grid cell focus ring redraws when the user toggles Light or Dark mode mid-session, picking up the system's appearance-aware focus indicator color
 - Data grid keeps sortedIDs and cachedRowCount paired by calling updateCache() immediately after the SwiftUI bridge writes new sortedIDs to the coordinator, removing a window where the cached count and the sort permutation could disagree
 - Display formats memoized per tab on MainContentCoordinator keyed by schema version, smart-detection setting, and format-overrides version, so ValueDisplayDetector.detect runs once per result schema instead of on every SwiftUI body evaluation
+- MCP HTTP router replaced with a route registry. `MCPRouter` now matches paths and methods against a list of `MCPRouteHandler` values; `/mcp` traffic and `/v1/integrations/exchange` traffic each live in their own handler file under `Core/MCP/Routes/`. OPTIONS preflight is handled once at the router level for every path
+- `MCPAuthGuard` and `MCPConnectionBridge` route concurrent dedup through a shared `OnceTask` actor (`Core/Concurrency/OnceTask.swift`). Cleanup of in-flight slots happens in `defer` inside the actor, so a cancelled or thrown caller no longer leaves a stale entry behind.
 
 ### Removed (BREAKING)

 - Persist group deletions before firing the sync notification, fixing a race that could re-upload deleted groups via iCloud.
 - Persist connection deletions before firing the sync notification, fixing the same race for deleted connections.
 - Refuse to generate SQL when the database dialect cannot be resolved, instead of silently emitting unquoted identifiers.
+- MCP `execute_query`: strip trailing semicolons before appending `LIMIT/OFFSET`, fixing `syntax error at or near LIMIT` for queries like `select * from t;`.
