//! DSH registry maps format versions to implementations or fallback.

//! See architecture.md#adapter-layout / #unknown-version, V30.

//!

//! Native rc.2 format 4 has nonempty real samples; retain the separate legacy session-log-doc-1 ID.

//! KnownVersion identifies a file format, not all client versions or inherited history.

//! select retains the shared fallback interface; detection rejects unknown explicit format versions.

/// This constant selects the latest built-in implementation without network access.

/// Legacy format ID based on README 46a7f68 event/replacement rules, not a product version.

/// Native format-4 samples do not verify this separate legacy format.

/// Registered format IDs mapped to implementations.

/// No per-product version mappings; keep native format 4 and the legacy ID separate.

/// Version selection result.

/// Detection and scanning share this V30 format-selection function.

// Detection rejects unknown explicit formats; retain the shared selection interface.

// Detection requires a native header or legacy shape; None preserves the common interface.

// Test fallback branches directly; successful detection supplies a supported native or legacy format.

// Preserve the same LatestFallback result shape as other registries for V30 checks.
