Module workflow 

High-level workflow — PDD §5 (steps 1–12).

Each function borrows &mut dyn Transport and (for channel steps) a backend and an open crate::scp::ScpSession, performs the pre-flight checks of its §5 subsection, drives the §command builders through the §scp session, and returns Result<XReport, ScllError> (§7/§8). No success payload is reachable on the error path.

Channel steps are generic over B: KeyBackend + Scp02Backend + Scp03Backend (Fork F-A): the open session may be either variant, so wrap/unwrap needs both backend traits. Pre-auth steps (probe, discover_card) take no backend. All per-step inputs are borrowed *Args structs (Fork F-C/D); the shared transport/SCP plumbing lives in session (Fork F-B).
