# Service Desk Architecture

The Service Desk pilot is a dependency-free Node domain module. `src/ticket.js`
contains the state transitions and SLA rule; `test/ticket.test.mjs` uses Node's
built-in test runner. CASAN governance is supplied only by
`packages/casan-harness`, selected through `CASAN_DOMAIN_ROOT`; no harness gate
is copied or modified for this project.
