prediction models (GNN/XGBoost) and moderation routers (ToxMod, Perspective, Hive) should operate asynchronously, feeding signals back to live-ops dashboards without blocking gameplay.

// ops-router.ts
import { createClient } from '@supabase/supabase-js';

const supabase = createClient(process.env.SUPABASE_URL!, process.env.SUPABASE_KEY!);

interface PlayerEvent {
  playerId: string;
  eventType: 'chat_message' | 'economy_trade' | 'session_end';
  payload: Record<string, unknown>;
  timestamp: number;
}

export async function routePlayerEvent(event: PlayerEvent): Promise<void> {
  if (event.eventType === 'chat_message') {
    const moderationPayload = {
      text: String(event.payload.text),
      playerId: event.playerId,
      channel: event.payload.channel || 'global'
    };
    
    // Async moderation check; does not block gameplay
    supabase.functions.invoke('moderation-check', { body: moderationPayload })
      .catch(err => console.error('[Ops] Moderation service unavailable:', err.message));
  }
  
  if (event.eventType === 'session_end') {
    const churnSignal = {
      playerId: event.playerId,
      sessionDuration: Number(event.payload.duration),
      lastInteraction: new Date(event.timestamp).toISOString()
    };
    
    supabase.functions.invoke('churn-scorer', { body: churnSignal })
      .catch(err => console.error('[Ops] Churn scoring failed:', err.message));
  }
}

Rationale: Edge functions decouple heavy inference from the game client. Moderation and churn scoring run asynchronously, preserving frame time and network latency. Failures are logged but never crash the session. This matches production requirements for 99.9% uptime and sub-50ms event routing.

Step 4: Implement Constrained Ship-Time PCG

Procedural content in the shipped binary must be deterministic, seed-controlled, and human-reviewed at scale. Use AI to generate candidate pools, then apply rule-based filters before runtime injection.

// pcg-quest-engine.ts
interface QuestTemplate {
  id: string;
  objective: string;
  rewardCurrency: string;
  rewardAmount: number;
  difficulty: number;
}

export class QuestGenerator {
  private seed: number;
  
  constructor(initialSeed: number) {
    this.seed = initialSeed;
  }
  
  private hashSeed(input: string): number {
    let h = this.seed;
    for (let i = 0; i < input.length; i++) {
      h = Math.imul(h ^ input.charCodeAt(i), 2654435761);
    }
    return h >>> 0;
  }
  
  generateQuestPool(candidates: QuestTemplate[], count: number): QuestTemplate[] {
    const pool: QuestTemplate[] = [];
    const usedIds = new Set<string>();
    
    for (let i = 0; i < count; i++) {
      const idx = this.hashSeed(`quest_${i}_${Date.now()}`) % candidates.length;
      const candidate = candidates[idx];
      
      if (!usedIds.has(candidate.id)) {
        pool.push({ ...candidate, id: `${candidate.id}_v${i}` });
        usedIds.add(candidate.id);
      }
    }
    
    return pool;
  }
}

Rationale: Deterministic seeding ensures reproducible quest pools across client/server boundaries. The generator filters duplicates and applies version tags for rollback capability. AI provides the candidate pool; the engine enforces distribution rules. This prevents runtime hallucination and economy inflation.

Action Checklist

• Schema Validation: Implement runtime type checking for all AI-generated content before it enters the data pipeline.
• Compliance Ledger: Track model versions, generation timestamps, and human review status for every shipped asset.
• Style Guide Database: Centralize tone rules, vocabulary restrictions, and negative examples for narrative and UI text.
• Async Ops Routing: Decouple moderation, churn scoring, and support triage from the main game loop using edge functions.
• Deterministic PCG: Seed procedural systems, enforce distribution rules, and maintain rollback capability for runtime content.
• Human Checkpoint: Route all hero strings, UI layouts, and audio master files through mandatory editor review before promotion.
• Latency Budgeting: Set strict timeout limits for runtime AI calls and implement graceful fallback responses.

Quick Start Guide

1. Initialize Validation Layer: Install Zod or TypeBox. Define schemas for your core content types (items, quests, dialogue). Wire validation into your content import script to reject malformed payloads before they reach the game data store.
2. Wire Dev-Time Agents: Configure Cursor or Claude Code with project-specific context files. Set up CI hooks that run automated linting, format optimization, and schema validation on every PR. Route AI-generated assets to a staging directory, not directly to committed.
3. Deploy Async Ops Hooks: Create edge functions for moderation routing and churn scoring. Integrate them into your event dispatcher so player actions trigger background analysis without blocking the main thread. Set timeout limits and fallback queues.
4. Establish Compliance Tracking: Add a metadata field to your asset pipeline that records model version, generation timestamp, and review status. Export this ledger automatically during build steps to satisfy platform disclosure requirements.
5. Run Deterministic PCG Tests: Seed your procedural generators with server-controlled values. Implement deduplication and distribution rules. Validate outputs against balance constraints before runtime injection. Iterate pool sizes based on simulation results.
