<Title — what changes, in one line>

Why

<The problem or need. Why this belongs in shared Core, not just one product.>

Current state

<How the affected surface behaves today in the origin repo. A small table of surface / pattern / consequence works well. Point at concrete files by sync key.>

Proposed change

<The change to make. Concrete: interfaces, method shapes, EF config, registration. Include short code snippets where they remove ambiguity. State decisions, not options.>

Affected shared surface

<List every Core file to touch, by sync key. Flag anything that may collide with a local #region project-specific fence in a receiving fork.>

Verification

<How the receiving repo confirms the change is correct: build command, the specific tests to run/add, and any manual check.>
