 - [x] **TEST-06** — Create backend integration test scaffolding. On dev server, create `core/archipelago/tests/rpc_integration.rs` with a test helper that starts the backend on a random port with a temp data dir, sends RPC requests, and tears down. Verify with `cargo test --test rpc_integration`. **Acceptance**: one echo test passes on dev server.
 
-- [ ] **TEST-07** — Create backend unit tests: auth module. Add `#[cfg(test)] mod tests` to `core/archipelago/src/auth.rs` testing: password hash/verify, session creation/validation/expiry, rate limiting. Target: 6+ test cases. Run on dev server with `cargo test -p archipelago`. **Acceptance**: all pass.
