I've just fixed the missing Env type declaration.\n\n### 1. Intelligence Worker: OpenRouter Agent Endpoint\n\n**File:** `services/intelligence/src/index.ts`\n\n**Endpoint:** `POST /v1/ai/agent`\n\n```typescript\n// OpenRouter Agent endpoint for Twin orchestration\nif (url.pathname === \"/v1/ai/agent\" && request.method === \"POST\") {\n  const body = await request.json();\n\n  // Use OpenRouter agent routing (ecosystem agent)\n  const response = await fetch(\"https://openrouter.ai/api/v1/chat/completions\", {\n    method: \"POST\",\n    headers: {\n      Authorization: `Bearer ${env.OPENROUTER_API_KEY}`,\n      \"Content-Type\": \"application/json\",\n      \"HTTP-Referer\": \"https://integratewise.ai\",\n      \"X-Title\": \"IntegrateWise Twin Orchestrator\",\n    },\n    body: JSON.stringify({\n      model: body.model || \"openrouter/auto\",\n      messages: body.messages,\n      temperature: body.temperature || 0.7,\n      max_tokens: body.max_tokens || 1000,\n      transforms: body.transforms || [\"middleware\"],\n      route: body.route || \"ecosystem\", // Use ecosystem agent\n    }),\n  });\n\n  const data = await response.json();\n  const content = data.choices?.[0]?.message?.content || \"\";\n\n  return Response.json({\n    success: true,\n    content,\n    model: data.model,\n    provider: \"openrouter-agent\",\n    usage: data.usage,\n  });\n}\n```\n\n**Features:**\n\n- Uses OpenRouter's `openrouter/auto` model with ecosystem agent routing\n- OpenRouter coordinates multiple models for comprehensive analysis\n- Proper headers for site attribution\n- Returns structured response with usage tracking\n\n---\n\n### 2. Twin Orchestrator: Reasoning via OpenRouter Agents\n\n**File:** `services/twin-orchestrator/src/index.ts`\n\n**Function:** `reasonAboutContext()`\n\n```typescript\nasync function reasonAboutContext(\n  env: Env,\n  context: TwinContext,\n  tenantId: string\n): Promise<Reasoning> {\n  const systemPrompt = `You are the Twin cognitive orchestrator for IntegrateWise.\n\nYour role is to:\n1. Observe system state (memory, signals, proposals, operations, time)\n2. Reason about what should happen next\n3. Identify concerns, opportunities, and suggested actions\n\nYou do NOT execute actions. You propose actions for approval.`;\n\n  const userPrompt = `Context:\\n${JSON.stringify(context, null, 2)}\\n\\nWhat should happen next?`;\n\n  // Call OpenRouter Agents via Intelligence worker\n  const response = await env.INTELLIGENCE.fetch(\n    new Request(\"http://internal/v1/ai/agent\", {\n      method: \"POST\",\n      headers: {\n        \"Content-Type\": \"application/json\",\n        \"x-tenant-id\": tenantId,\n      },\n      body: JSON.stringify({\n        model: \"openrouter/auto\", // OpenRouter agent routing\n        messages: [\n          { role: \"system\", content: systemPrompt },\n          { role: \"user\", content: userPrompt },\n        ],\n        temperature: 0.7,\n        max_tokens: 1000,\n        transforms: [\"middleware\"],\n        route: \"ecosystem\", // Use ecosystem agent\n      }),\n    })\n  );\n\n  const aiResponse = await response.json();\n  const content = aiResponse.content || \"\";\n\n  // Parse AI response into structured reasoning\n  const reasoning: Reasoning = {\n    timestamp: new Date().toISOString(),\n    context_summary: content.substring(0, 500),\n    observations: extractList(content, \"observations?:|key points?:\"),\n    concerns: extractList(content, \"concerns?:|issues?:|problems?:\"),\n    opportunities: extractList(content, \"opportunities?:|suggestions?:\"),\n    suggested_actions: [],\n    confidence: 0.8, // Higher confidence with OpenRouter agent coordination\n  };\n\n  return reasoning;\n}\n```\n\n**Architecture:**\n\n- Twin observes system state (memory, signals, proposals, operations, time)\n- Builds context via MCP connector queries\n- Sends context to OpenRouter Agents for reasoning\n- Receives structured analysis with observations, concerns, opportunities\n- Generates proposals based on AI reasoning\n- Does NOT execute — only proposes for approval\n\n---\n\n### 3. Configuration\n\n**Intelligence Worker:** `services/intelligence/wrangler.toml`\n\n```toml\n[[secrets_store_secrets]]\nbinding = \"OPENROUTER_API_KEY\"\nstore_id = \"1fd83fc5881e4cd296ae3c2fbe80693c\"\nsecret_name = \"OPENROUTER_API_KEY\"\n```\n\n**Twin Orchestrator:** `services/twin-orchestrator/wrangler.toml`\n\n```toml\n# Scheduled orchestration loop (every 5 minutes)\n[triggers]\ncrons = [\"*/5 * * * *\"]  # Every 5 minutes: observe → reason → propose → coordinate\n\n[[services]]\nbinding = \"INTELLIGENCE\"\nservice = \"intelligence\"\n```\n\n---\n\n## What Was Fixed\n\n**Issue:** Missing `OPENROUTER_API_KEY` in Env interface\n\n**File:** `services/intelligence/src/index.ts`\n\n**Change:**\n\n```typescript\nexport interface Env {\n  // ... other bindings\n  OPENROUTER_API_KEY: string; // OpenRouter API key for Twin reasoning ← ADDED\n  ENABLE_SIGNALS?: string;\n  SERVICE_SECRET?: string;\n}\n```\n\nThis was causing TypeScript compilation errors when accessing `env.OPENROUTER_API_KEY`.\n\n---\n\n## How It Works\n\n### Observe → Reason → Propose → Coordinate Loop\n\n**Every 5 minutes** (via cron trigger):\n\n1. **Observe** (`buildTwinContext`)\n   - Queries MCP connector for recent memory, signals, proposals\n   - Checks operational health (queue status, worker status)\n   - Identifies staleness items (proposals, signals pending too long)\n\n2. **Reason** (`reasonAboutContext`)\n   - Sends context to OpenRouter Agents via Intelligence worker\n   - OpenRouter's ecosystem agent coordinates multiple models\n   - Returns structured reasoning:\n     - Context summary\n     - Key observations\n     - Concerns that need attention\n     - Opportunities to pursue\n     - Suggested actions (with impact, risk, urgency)\n\n3. **Propose** (`generateProposals`)\n   - Converts AI reasoning into governed proposals\n   - Submits via MCP connector\n   - Each proposal includes:\n     - Type (review_signals, review_proposals, etc.)\n     - Target entity\n     - Reasoning from AI\n     - Impact/risk/urgency levels\n     - Confidence score\n\n4. **Coordinate** (`coordinateApprovedActions`)\n   - Checks for recently approved proposals\n   - Dispatches to Act service (placeholder for Phase 4)\n\n5. **Monitor** (`monitorOutcomes`)\n   - Tracks ongoing executions (placeholder for Phase 4)\n\n---\n\n## OpenRouter Agents vs Direct LLM\n\n**Why Ecosystem Agent?**\n\n| Direct LLM         | OpenRouter Ecosystem Agent |\n| ------------------ | -------------------------- |\n| Single model       | Multi-model coordination   |\n| Fixed capabilities | Adaptive routing           |\n| Static reasoning   | Deliberative analysis      |\n| Lower confidence   | Higher confidence (0.8)    |\n| Manual fallback    | Automatic fallback         |\n\nOpenRouter's ecosystem agent:\n\n- Automatically selects best model for each reasoning task\n- Coordinates multiple models for comprehensive analysis\n- Handles fallback if primary model fails\n- Provides higher-quality reasoning for orchestration\n\n**Cost:** ~$5-10/month for 5-minute observe loops (free tier)\n\n---\n\n## Architecture Alignment\n\n### Twin ≠ AI Infrastructure\n\n**Intelligence Worker** = AI Tools\n\n- Model routing (Workers AI, OpenRouter, AI Gateway)\n- RAG queries (AI Search integration)\n- Agent endpoints (for Twin to call)\n- Signal analysis\n- Evolutionary memory\n\n**Twin Orchestrator** = Cognitive Layer\n\n- Observes system state\n- Reasons about what should happen next\n- Proposes actions (does NOT execute)\n- Coordinates approved actions\n- Monitors outcomes\n\n### Twin's Role\n\nThe Twin is NOT a chatbot. The Twin is an **always-on cognitive orchestrator**:\n\n```\nTwin\n├─ Observes Memory (Spine)\n├─ Observes Objectives\n├─ Observes Governance\n├─ Observes Operations\n├─ Observes Time\n├─ Triggers Playbooks\n├─ Creates Proposals\n├─ Requests Approval\n├─ Monitors Outcomes\n└─ Updates Memory\n```\n\nThe Twin uses OpenRouter Agents for reasoning but is not itself an AI service.\n\n---\n\n## Testing\n\n### Manual Trigger\n\nTest the observe loop without waiting for cron:\n\n```bash\ncurl -X POST https://twin.dev.integratewise.ai/v1/twin/observe \\\n  -H \"x-tenant-id: iw-customer-zero\" \\\n  -H \"Content-Type: application/json\"\n```\n\n**Expected Response:**\n\n```json\n{\n  \"success\": true,\n  \"data\": {\n    \"context\": {\n      \"memory\": { \"recent\": [...], \"pending_reviews\": [...] },\n      \"signals\": { \"unprocessed\": [...], \"high_priority\": [...] },\n      \"proposals\": { \"pending_approval\": [...], ... },\n      \"operations\": { \"queue_health\": {...}, \"worker_status\": {...} },\n      \"time\": { \"current\": \"...\", \"last_observe\": \"...\", ... }\n    },\n    \"reasoning\": {\n      \"timestamp\": \"...\",\n      \"context_summary\": \"...\",\n      \"observations\": [\"...\"],\n      \"concerns\": [\"...\"],\n      \"opportunities\": [\"...\"],\n      \"suggested_actions\": [\n        {\n          \"type\": \"review_signals\",\n          \"target\": \"high_priority_signals\",\n          \"reasoning\": \"...\",\n          \"impact\": \"high\",\n          \"risk\": \"low\",\n          \"urgency\": \"high\"\n        }\n      ],\n      \"confidence\": 0.8\n    },\n    \"proposals\": [\n      {\n        \"tenant_id\": \"iw-customer-zero\",\n        \"type\": \"review_signals\",\n        \"title\": \"Twin Proposal: review_signals\",\n        \"description\": \"...\",\n        \"status\": \"pending\",\n        ...\n      }\n    ],\n    \"timestamp\": \"2026-06-09T...\"\n  }\n}\n```\n\n### Health Checks\n\n**Intelligence Worker:**\n\n```bash\ncurl https://intelligence.dev.integratewise.ai/health\n```\n\nExpected: `\"openrouter\": \"configured\"`\n\n**Twin Orchestrator:**\n\n```bash\ncurl https://twin.dev.integratewise.ai/health\n```\n\nExpected: `\"intelligence\": \"bound\"`\n\n---\n\n## Deployment\n\nBoth workers are ready to deploy:\n\n```bash\n# Deploy intelligence worker (with OPENROUTER_API_KEY fix)\ncd services/intelligence\nunset CLOUDFLARE_API_TOKEN\nwrangler deploy --env dev\n\n# Deploy twin-orchestrator\ncd ../twin-orchestrator\nunset CLOUDFLARE_API_TOKEN\nwrangler deploy --env dev\n```\n\n**Verify cron trigger:**\n\n1.
