 Goal:
 
 Prepare the current SQLite implementation for persistent history and a later PostgreSQL adapter without changing user-facing behavior.
@@ -358,6 +360,8 @@ Implemented foundation:
 - all general application repositories require an explicit database context;
   server composition owns their runtime instances and controllers contain no
   direct global SQLite access
+- TypeScript maintenance and upgrade scripts have a dedicated no-emit

 - the legacy consumer UI and application read/write endpoints are removed after verified data cutover
 - retained legacy rows are accessible only through explicit database upgrade tooling
 - project devices no longer persist duplicate legacy power, phase, cosPhi or remark fields
