Preset application does not change sync ownership toggles (SyncEnabled, LocalOnlyMode, AcceptHostSync).

Networking

• Sync is host-authoritative with strict host verification.
• Client handshake flow: Hello -> HelloAck -> StateRequest -> StateSnapshot.
• Validation includes nonce, host identity, session epoch, revision order, and state hash.
• No first-sender authority pinning.
• Client opt-out is supported via Allow Host Sync.

Compatibility

• Host->client sync requires both host and client to have ShaderPlayground installed.
• ob.otAPI is optional (soft dependency).

Default Input

• F10 toggles ShaderPlayground UI.

Release v0.5.2

• Added new preset: Pitch Black with tuned low-light settings from captured profile screenshots.
• Added strict host-verified ShaderPlayground sync handshake (host->client):
  • explicit client state machine (Disconnected, AwaitHelloAck, AwaitSnapshot, Synced, Stale)
  • v2 message flow (Hello, HelloAck, StateRequest, StateSnapshot)
  • nonce, session-epoch, revision, and state-hash validation
  • duplicate/stale/gap snapshot handling with automatic resync requests
• Removed dependence on first-sender authority pinning for shader sync acceptance.
• Added explicit host identity verification using lobby owner SteamID + player-panel sender mapping.
• Added host migration/session change detection and forced re-handshake behavior.
• Added built-in in-game handshake diagnostics in Tools tab:
  • live sync state + reason
  • expected host sender/steam IDs
  • active epoch + accepted revision/hash
  • rolling sync event log + clear/status actions
• Added sync logging config controls:
  • Debug.EnableBuiltInSyncLog
  • Debug.SyncLogToBepInEx
  • Debug.SyncLogIncludeKeepalive
• Updated automated tests for new sync policy behavior and cadence handling.
• Synced package metadata/version fields to 0.5.2.
