+//! CR-001 — SPV mn-list sync readiness.
+//!
+//! Spec: `tests/e2e/TEST_SPEC.md` (### Core (CR) → CR-001).
+//!
+//! Pins the SPV-readiness contract: the mn-list manager reaches
+//! `SyncState::Synced`, the synced height is > 0, and the SPV runtime
+//! is in a started (running) state on return. The spec's informational
+//! warm-cache target is 180 s; the helper internally raises every
+//! request to its `COLD_CACHE_TIMEOUT_FLOOR` (600 s) so the actual
+//! wait can be longer on a cold testnet cache.
+//!
+//! The harness already calls `wait_for_mn_list_synced` during
+//! `E2eContext::build`; this test re-asserts the same contract from the
+//! test-body perspective to keep the pin explicit and independently
+//! verifiable. The call returns immediately when the harness already
+//! cleared the gate.
+//!
+//! Mirrors DET's `test_spv_sync_and_create_wallet` at
+//! `dash-evo-tool/tests/backend-e2e/spv_wallet.rs:14`.
