11 — Achievements, Progression & Meta Systems (Systems 102-103)

Category Purpose: These 2 systems handle meta-progression — progress statistics tracking across sessions and the achievement/unlock system with platform integration.

#	System	Asset Type	Role
102	BPC_ProgressStatTracker	Component	Progress stats; total playtime, collectibles, achievements
103	SS_AchievementSystem	Subsystem	Achievement subsystem; unlock, notify, platform integration

102 BPC_ProgressStatTracker: Tracks cumulative stats across play sessions: total playtime, collectibles found, enemies killed, deaths, items crafted, documents read, endings seen. Persists via I_Persistable for long-term tracking.

103 SS_AchievementSystem: GameInstanceSubsystem that manages achievement unlocks. Listens to gameplay events (enemy killed, item found, chapter completed) and unlocks achievements when conditions met. Shows notification toast on unlock. Integrates with platform achievement APIs (Steam, PlayStation, Xbox).

12 — Settings, Accessibility, Haptics, Render Pipeline & Platform Systems (Systems 104-105, 148-149)

#	System	Asset Type	Role
104	BPC_AccessibilitySettings	Component	Accessibility; subtitles, colorblind, controller remap
105	SS_SettingsSystem	Subsystem	Settings subsystem; persistent settings, apply, reset
148	BPC_HapticsController	Component	Haptics controller; GameplayTag-driven force feedback, DualSense triggers, heartbeat pulse
149	BPC_RenderPipelineManager	Component	Render pipeline manager; quality presets, per-platform GI/shadows/upscaling, PlanarCapture aware

104 BPC_AccessibilitySettings: Manages accessibility features: subtitle toggle/size, colorblind mode selection (protanopia/deuteranopia/tritanopia), controller remapping, difficulty presets, hold-to-confirm toggle, camera shake reduction. Settings persisted via SS_SettingsSystem.

105 SS_SettingsSystem: GameInstanceSubsystem for all persistent settings. Loads defaults on init, saves on change, supports reset-to-default. Settings categories: Audio, Video, Controls, Gameplay, Accessibility. Coordinates with SS_AudioManager for volume, SS_EnhancedInputManager for key rebinding.

148 BPC_HapticsController: ActorComponent attached to the Player Controller. Central abstraction for all controller vibration and force feedback. Systems trigger haptics by GameplayTag (e.g., Haptic.Damage.Heavy) — never calling raw UE5 Play Force Feedback nodes. Handles platform detection (Xbox rumble, PS5 DualSense adaptive triggers, PC generic gamepad), respects accessibility toggle, manages effect priority/conflict resolution, and drives the continuous heartbeat pulse from BPC_StateManager.GetCurrentHeartRate(). Uses DA_HapticProfile Data Assets for all effect definitions.

149 BPC_RenderPipelineManager: ActorComponent attached to the Player Controller. Central authority for UE5 render pipeline configuration. Reads DA_RenderPipelineProfile Data Assets to determine the appropriate rendering method (Lumen vs Baked Lightmass), shadow system (VSM vs CSM), upscaler (DLSS/FSR/TSR/PSSR), and mesh strategy (Nanite vs LOD) for the current platform and quality preset. Applies settings via UE5 console variables, coordinates with BPC_PerformanceScaler for runtime quality tier adjustments, and broadcasts pipeline changes so the Planar Capture system can adjust its quality budget. Handles reload-required detection for destructive pipeline changes (GI method, shadow method, Nanite toggle).

108 BPC_ErrorHandler: Global error handling: catches blueprint errors, logs to file, displays error toast (dev builds only). Graceful recovery from non-fatal errors.

109 BPC_FPSCounter: Simple FPS display overlay with min/max/avg tracking. Toggle via debug menu or console command.

110 BPC_LoadingScreen: Loading screen widget with progress bar, gameplay tips, background art. Manages level streaming progress display.

111 BPC_TutorialSystem: Context-sensitive tutorial prompts. Triggered by gameplay events (first combat, first hide, first puzzle). Tracks which tutorials the player has seen. Supports dismiss/snooze.

112-114 Widgets: Credits screen with scroll and post-credit scene trigger. Debug menu for development. Splash screen with studio/engine logos.

14 — Data Assets (Systems 115-127, 129, 134-135)

Category Purpose: These 16 systems define all Data Asset types used across the framework. Data Assets are the primary configuration mechanism — all content, rules, and settings live in these assets, never hardcoded in Blueprints.

#	Data Asset	Configures
115	DA_AdaptationRule	Difficulty adaptation rules (metric thresholds, responses)
116	DA_AtmosphereProfile	Atmosphere: audio ambience, lighting, fog, post-process per mood
117	DA_BehaviourVariant	AI behavior variant: attack patterns, patrol style, aggression
118	DA_DataAssetArchitecture	Overview document of all Data Asset types
119	DA_EncounterData	Encounter definitions: enemy groups, spawn rules, difficulty tier
120	DA_EquipmentConfig	Equipment/weapon stats: damage, fire rate, magazine, recoil
121	DA_HapticProfile	Haptic/force feedback patterns for controller
122	DA_InteractionData	Interaction definitions: prompt text, duration, icon, conditions
123	DA_ObjectiveData	Objective/quest: description, prerequisites, rewards, branching
124	DA_PuzzleData	Puzzle definitions: solution, steps, hints, rewards
125	DA_RareEvent	Rare event: weight, conditions, effects, cooldown
126	DA_RoomMutation	Room mutation: layout change, object swap, lighting change
127	DA_ScareEvent	Scare event: type, anticipation duration, payoff, recovery
129	DA_InputMappingProfile	Input mappings per platform (PC, Xbox, PS5)
134	DA_AudioSettings	Audio bus configs, volume defaults, ducking, pool limits
135	DA_RoomAcousticPreset	Room acoustics: 7 presets (Outdoor, SmallRoom, Cave, etc.)

Pattern: All Data Assets derive from UPrimaryDataAsset. They are pure data containers — no runtime logic. Designers edit these in the Content Browser; systems read them at runtime. This is the "No Hardcoded Names" principle in practice.

15 — Enhanced Input System (System 128)

#	System	Asset Type	Role
128	SS_EnhancedInputManager	Subsystem	Input manager; context switching, rebinding, platform profiles

128 SS_EnhancedInputManager: The sole authority for all input management. Handles Input Mapping Context push/pop with priority-based context switching. Coordinates input mode (game-only vs UI-only) with SS_UIManager. Manages key rebinding via DA_InputMappingProfile. Platform-specific bindings (PC keyboard/mouse, Xbox controller, PS5 controller). Gameplay systems query input state through this subsystem — never through raw Enhanced Input calls.

Context Priority Ladder: Default(0) < Hiding(5) < WristwatchUI(10) < Inspection(20) < UI(100). Higher priority contexts override lower ones — UI blocks gameplay input.

---

16 — State Management (Systems 130-131)

#	System	Asset Type	Role
130	BPC_StateManager	Component	Central state authority; action gating, overlay, vital signs
131	DA_StateGatingTable	Data Asset	All state gating rules (37 action rules); designer-editable

130 BPC_StateManager: The single source of truth for player capability. Manages 42 exclusive action states and 18 overlay states. All systems query IsActionPermitted(Tag) instead of checking each other's states directly. This is the central decoupling mechanism — the StateManager knows what's allowed; no individual system needs to know about others.

131 DA_StateGatingTable: A Data Asset containing all gating rules. Designers modify which actions are blocked during which states without touching Blueprints. For example: "Reloading blocks Sprint" or "Hiding blocks Interaction."

Multiplayer Networking

Category 11-12: Meta & Settings

System	Authority
BPC_ProgressStatTracker	Server accumulates; snapshot replicates for scoreboard
SS_AchievementSystem	Server validates unlocks; client receives unlock notifications
BPC_AccessibilitySettings	Local per-client — each player's accessibility preferences
SS_SettingsSystem	Settings save per-client; key bindings are local
BPC_HapticsController	Local client only — haptics are cosmetic, never replicated. No HasAuthority() needed.
BPC_RenderPipelineManager	Local client only — render pipeline is per-client hardware. No replication.

Category 13: Polish

System	Authority
BPC_AnalyticsTracker	Local only — per-client telemetry
BPC_DevCheatManager	Local only — but cheats that affect world must be server-validated
BPC_ErrorHandler	Local only — per-client error handling
BPC_FPSCounter	Local only — per-client performance
BPC_LoadingScreen	Local only — but sync'd via GamePhase
BPC_TutorialSystem	Local per-client — tutorial progression is per-player
WBP_CreditsScreen, WBP_DebugMenu, WBP_SplashScreen	Local only

Category 14: Data Assets

All DA_* Data Assets are read-only configuration — loaded identically on all clients. No replication needed.

Category 15: Input

System	Authority
SS_EnhancedInputManager	Local per-client. Input mapping contexts, key rebinding, and input mode are per-player. Context priority stack is per-client.

Category 16: State Management

System	Authority
BPC_StateManager	Server-authoritative. All state change requests go through server. IsActionPermitted() is read-only — safe for client prediction. RequestStateChange() must be server-validated.
DA_StateGatingTable	Read-only Data Asset — identical on all clients. Server uses it for validation; clients use it for prediction of gating results.
