2//
3// Env vars must be set BEFORE any module that reads them is imported. auth.ts
4// calls getDb() at module evaluation, so we mutate process.env first and pull
5// every framework module in via dynamic import to keep the invariant when
6// this file is loaded alongside siblings that may have already cached
7// session.ts / cli-jwt.ts.
8//
9// The happy-path test mints a CLI bearer token in-process and hits the route
10// via Hono's request() helper — matching the pattern in
11// apps/api/src/middleware/session.test.ts. We accept either 200 (route ran
12// end-to-end including the audit insert) OR 500 (DB unreachable in test env)
13// since the test environment doesn't stand up postgres. The 401 path is
14// always clean because it short-circuits before any DB call.
