New multiplayer game mode where Dolphin players race along a track, collect crystals to charge explosions, and destroy dartboard structures. Winner is first to reach hostile volume destruction threshold. New scripts: - NeedleThreadController: multiplayer race controller with volume-based win - NeedleThreadScoreTracker: tracks elapsed time and volume destroyed - VolumeDestructionTurnMonitor: ends turn when volume threshold reached - NeedleThreadEndGameController: victory/defeat with time or echo hits left - NeedleThreadScoreboard: formats winner time and loser echo hits - NeedleThreadHUD/HUDView: live hostile volume destroyed display - NeedleThreadStatsReporter: UGS telemetry reporting Modified: - GameModes enum: added NeedleThread = 39 - CallToActionTargetType: added PlayGameNeedleThread = 435 - UGSStatsManager: added ReportNeedleThreadStats method - ArcadeGameNeedleThreader.asset: updated Mode, DisplayName, Description, SceneName, Vessels (Dolphin), and CTA target https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
GameDataSO lives in CosmicShore.Soap namespace. The stats reporter references it directly as a serialized field, unlike the controller and score tracker which inherit it from base classes. https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
- SkimmerImpactor.OwnDomain and isInitialized now null-check the skimmer reference before accessing Domain/IsInitialized, preventing NullRef when collisions happen before VesselController.Initialize() completes - Create DolphinVesselTelemetry with ExplosionsTriggered and VolumeDestroyed tracking (Dolphin previously fell through to DefaultVesselTelemetry) - Register DolphinVesselTelemetry in VesselTelemetryBootstrapper switch https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
The Dolphin's charge→explosion ability was completely broken: 1. VesselChangeResourceByPrismEffectSO: Script used old API (halved resource instead of adding charge). Now uses ResourceChangeSpec matching the asset's _change field (adds 0.5 to Energy per prism hit) 2. DolphinVesselChangeResourceByCrystalEffect: Wrong resource index (1=Boost instead of 0=Energy). Fixed to consume Energy when hitting crystal. 3. DolphinVesselExplosionByCrystalEffect: Wrong resource index (1=Boost instead of 0=Energy). Fixed so explosion scales off accumulated charge. 4. NeedleThread scene: Added DartBoard prefab to SegmentSpawner's guaranteedSpawnables so dartboard structures spawn alongside the track. https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
The DartBoard prefab had a stale 'trailBlock' field name that didn't match
the renamed 'greenPrism' (via FormerlySerializedAs("greenTrailBlock")),
causing both greenPrism and redPrism to be null at runtime. This produced
"The Object you want to instantiate is null" in SpawnLeafObjects.
Now correctly references GreenDartBlock and RedDartBlock prefabs.

- GreenDartBlock: fix null onPrismVolumeModified and onPrismStolen SO refs that caused NullReferenceException in PrismScaleAnimator.ExecuteOnScaleComplete - PrismScaleAnimator: add null-safety for onPrismVolumeModified.Raise() - SpawnableDartBoard: add hostileToAll flag (Domains.None) so all prisms are hostile to every player's explosions - DartBoard.prefab: enable hostileToAll by default - SegmentSpawner: add ConfigureGuaranteedDistribution() for distributing guaranteed shapes along the track at each segment position - NeedleThreadController: distribute DartBoards along track at 0.2x scale instead of one large cluster 420 units from origin https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
- NeedleThreadController: change dartBoardScaleFactor from 0.2 to 0.5 (half of original size, not 5x smaller which made them invisible) - PrismEffectHelper: silently skip damage when Player is null instead of spamming LogError — this happens when vessel collides with prisms before player assignment completes during game start https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
The previous approach called Spawn() repeatedly on the same prefab-based SpawnableBase reference, which caused cache/state issues resulting in only one DartBoard appearing. Now instantiates an independent copy of the SpawnableDartBoard for each segment position, calls Spawn() on the fresh instance, then destroys the temporary spawnable. Each Spawn() call has clean state and produces a fully initialized DartBoard. https://claude.ai/code/session_01DgiJuVhagfk4BufQqsrrB8
