Expense Claims (Auto-Evaluation) — Basic Spec

Stack: C# + Sekiban (reuse Weather sample structure), Blazor (1 page), Sekiban Documents via MCP. Assumption: Single user context (e.g., demo-user).

Goal

Let one user run multiple parallel expense stories. Small claims auto-approve; big ones get flagged; a monthly cap blocks excess. Show intent via commands + timeline.

HTTPSClient with Zewo 0.5 bad connection.

I am testing my Zewo 0.3 Project with Zewo 0.5

OSX El Capitan. Using bash, each snapshot installed

Using 0.3 with DEVELOPMENT-SNAPSHOT-2016-02-08-a

Using 0.5 with DEVELOPMENT-SNAPSHOT-2016-04-12-a

Both make it build and run
