 ### Reuse Notes
-Scenarios are fully data-driven via `DA_ScenarioData`. Designers configure spawn tags, objective tags, time limits, and cleanup actions without blueprint modifications. Supports mixed scenarios: combat + investigation, timed + untimed, survival + objective.

+## Manual Implementation Guide
+
+### Class Setup
+1. Create Blueprint Class: Parent = `ActorComponent`, Name = `BPC_TrialScenarioSystem`
+2. Add to Player Character or GameMode
+
+### Variable Init (BeginPlay)
+```
+Event BeginPlay
+  ├─ Set ScenarioState = Inactive
+  └─ Cache: BPC_NarrativeStateSystem, BPC_ObjectiveSystem
+```
+
+### Function Node-by-Node
+
+#### `StartScenario(ScenarioData: DA_ScenarioData)` → `void`
+```
+Step 1: If ScenarioState != Inactive → Return (already running)
+Step 2: Set ActiveScenario = ScenarioData, ScenarioState = SetupRunning
+Step 3: Create checkpoint via SS_SaveManager (auto-save before trial)
+Step 4: Spawn enemies: ForEach ScenarioData.SpawnTags → Spawn Actor from Class at SpawnPoints
+Step 5: Lock doors/block exits: ForEach ScenarioData.BlockActor → Set enabled=false
+Step 6: If ScenarioData.bShowObjective: ActivateObjective(ScenarioData.ObjectiveTag)
+Step 7: Set ScenarioStartTime = Get Game Time
+Step 8: ScenarioState = ActiveRunning
+Step 9: Fire OnScenarioStarted
+```
+
+#### `EvaluateScenario()` → `void` *(Called on Tick or timer)*
+```
+Step 1: If ScenarioState != ActiveRunning → Return
+Step 2: Check success conditions:
+  If ScenarioData.SuccessFlags: HasAllFlags? → Call OnScenarioSuccess()
+  If ScenarioData.SuccessKillCount: enemies killed >= count? → Success
+Step 3: Check failure conditions:
+  If ScenarioData.TimeLimit > 0 AND (Now - StartTime) >= TimeLimit → OnScenarioFailure("Time expired")
+  If player death detected → OnScenarioFailure("Player died")
+```
+
+#### `OnScenarioSuccess()` → `void`
+```
+Step 1: ScenarioState = Success
+Step 2: ForEach ScenarioData.SuccessFlags → BPC_NarrativeStateSystem.SetFlag(flag, true)
+Step 3: If Objective active: CompleteObjective(ObjectiveTag)
+Step 4: Fire OnScenarioCompleted(true)
+Step 5: Call CleanupScenario()
+```
+
+### Build Checklist
+- [ ] Create component with DA_ScenarioData reference
+- [ ] Implement StartScenario: setup → spawn → lock → objective → active
+- [ ] Implement EvaluateScenario: check win/loss conditions per tick
+- [ ] Implement OnScenarioSuccess/Failure with flag setting
+- [ ] Implement CleanupScenario: despawn enemies, unlock doors
