1. Extend Integration Composition

• 1.1 Identify the shared integration/composition entry points that currently construct networking services with a single transport.
• 1.2 Update the relevant constructors or factory methods to accept an optional sync transport alongside the primary reliable transport.
• 1.3 Preserve backward-compatible call paths so existing single-transport composition still builds and defaults correctly.

2. Wire Dual Transports Through Session Services

• 2.1 Update session-scoped networking services to retain both transport references provided by the integration layer.
• 2.2 Route sync-designated traffic to the sync transport when present and fall back to the reliable transport otherwise.
• 2.3 Ensure the shared wiring keeps host-specific transport policy out of Unity-only or integration call sites.

3. Verify Regression Coverage

• 3.1 Add or update edit-mode tests for client single-session composition with both reliable and sync transports.
• 3.2 Add or update edit-mode tests for server multi-session composition when no dedicated sync transport is provided.
• 3.3 Run dotnet build Network.EditMode.Tests.csproj -v minimal and dotnet test Network.EditMode.Tests.csproj --no-build -v minimal after implementation.
