//! M4 sync integration tests: every rule of SPEC §14.4.2 (pull) and §14.4.4 (push steps 1 to 12), each rejection
//! reason of §14.4.6, the §9.10 conflict cases, batch limits, `cursor_ahead`, the epoch, the 14-day offline scenario
//! (AC-15.6), the audit writer (§14.4.7), `rotate-epoch` (§10.4), the end-to-end path device A push → device B pull,
//! and the orchestrator-assigned `serve` fixes (ConnectInfo for the rate limiter, `/i/` HTML 404).
//!
//! Reuses M3's harness (`tests/core_api/common.rs`) with the real `SqlAuditWriter` swapped in (`m4.rs`).
