Frontend Layer: React SPA at `app.integratewise.ai`\n\n### 1.1 Authentication Flow (AppShell.tsx)\n\n**File**: `/Users/nirmal/Github/integratewise-live/apps/web/src/AppShell.tsx`\n\n```typescript\n// Provider Stack (outermost → innermost):\nErrorBoundary → AuthProvider → SpineProvider → GoalProvider →\nHydrationFabric → WorkspaceShellNew\n\n// Stage Flow:\nlogin → signup → provisioning → onboarding (L0) → loading → workspace (L1)\n```\n\n**Auth Implementation**:\n\n- **Spine DB PKCE** with Google SSO, GitHub SSO, email/password\n- **Session Restore**: Auto-detects returning users via `user_metadata.onboarding_complete`\n- **Tenant Provisioning**: Refreshes session until `app_metadata.tenant_id` appears (DB trigger writes it)\n- **Onboarding Gate**: New users go through 6-step OnboardingFlow before workspace access\n\n**API Client Initialization** (`api-client.ts`):\n\n```typescript\ninitApiClient({\n  getAccessToken: () => authRef.current.accessToken,\n  getTenantId: () => user?.user_metadata?.tenant_id || user?.app_metadata?.tenant_id,\n  getUserId: () => authRef.current.user?.id,\n  getViewContext: () => resolveViewContext(domain, department),\n});\n```\n\n**Headers Injected on Every Request**:\n\n- `Authorization: Bearer <JWT>` — Spine DB session token\n- `x-tenant-id` — Tenant isolation\n- `x-user-id` — OAuth state binding + connector callback\n- `x-view-context` — Active workspace domain (CTX_CS, CTX_SALES, etc.)\n- `x-idempotency-key` — Write operation deduplication\n- `x-approval-token` — Act operation authorization\n\n---\n\n### 1.2 Workspace Architecture (workspace-shell-new.tsx)\n\n**File**: `/Users/nirmal/Github/integratewise-live/apps/web/src/components/l1/workspace/workspace-shell-new.tsx`\n\n**Layout Structure**:\n\n```\n┌─────────────────────────────────────────────────────────────┐\n│ Sidebar (260px)                                             │\n│  -

Gateway is the ONLY Entry Point**\n\n- ✅ All frontend requests go through `gateway.integratewise.ai`\n- ✅ No service can be reached directly (service bindings are internal)\n- ✅ JWT validation + tenant injection happens at Gateway only\n\n**2. Pipeline is the ONLY Spine Writer (Fortress Pattern)**\n\n- ✅ Pipeline service has exclusive Spine DB credentials\n- ✅ All other services read via Pipeline HTTP API\n- ✅ No service bypasses the 8-stage normalizer\n\n**3. Schema Drives Extraction (No Placeholders)**\n\n- ✅ Loader reads `tenant_spine_config` before extraction\n- ✅ Only schema-defined entity types are extracted\n- ✅ S3 Filter stage drops entities not in schema\n- ✅ S5 Extract stage prunes fields not in schema\n- ✅ No fake/placeholder records generated\n\n**4. HITL Gates High-Risk Actions (No Auto-Merge)**\n\n- ✅ S7.5 Identity Resolution creates `merge_candidate` records\n- ✅ Merge candidates require HITL approval via `/api/v1/cognitive/hitl/queue`\n- ✅ No automatic merging of cross-source duplicates\n- ✅ Act operations require approval token\n\n**5. Sanity Checks Enforce Quality (Score ≥70 Required)**\n\n- ✅ S7 Sanity stage runs rule-based + AI-powered checks\n- ✅ Records with score <70 are quarantined (not written to Spine)\n- ✅ Quarantine records written to `pipeline_quarantine` table\n- ✅ DLQ captures failed records for manual review\n\n**6. Projection-Based Entitlement**\n\n- ✅ ContentRouter checks `projectedModules` before rendering\n- ✅ Navigation built from projection service (entitlement-driven)\n- ✅ Fallback to product-based nav if projection unavailable\n\n**7. Density Gating (Data-Driven Rendering)**\n\n- ✅ `shouldRenderModule(dataContext, domain, \"default\")` checks data availability\n- ✅ Shows `<EmptyState>` if insufficient data\n- ✅ Prevents rendering empty modules\n\n---\n\n## 8.

Provisioning loop waits for tenant_id to appear in JWT\n```\n\n### 11.2 Tenant Isolation\n\n**Row-Level Security (RLS)** in Spine DB:\n\n```sql\n-- All Spine tables have RLS enabled\nCREATE POLICY \"tenant_isolation\" ON account_success.accounts\n  FOR ALL\n  USING (tenant_id = current_setting('request.jwt.claims')::json->>'tenant_id');\n\n-- Gateway injects x-tenant-id header\n-- Spine DB client uses it for RLS enforcement\nconst spineDb = createClient(env.SPINE_URL, env.SPINE_ANON_KEY, {\n  global: { headers: { \"x-tenant-id\": tenantId } },\n  db: { schema },\n});\n```\n\n**Service-Level Isolation**:\n\n```typescript\n// Every service binding call includes tenant context\nfunction routeRequest(request: Request, env: Env, target: RouteTarget): Promise<Response> {\n  const tenantId = getTenantId(request); // from x-tenant-id header\n  const fetcher = env[target] as Fetcher;\n  return resilientFetch(serviceName, fetcher, request, tenantId);\n}\n```\n\n### 11.3 Rate Limiting\n\n**IP-Based Edge Throttling**:\n\n```typescript\nconst ip = request.headers.get(\"cf-connecting-ip\") || \"unknown\";\nconst ipRateKey = `ip:${ip}:${Math.floor(Date.now() / 60000)}`;\nconst currentIpCount = parseInt((await env.RATE_LIMITS.get(ipRateKey)) || \"0\", 10);\nif (currentIpCount >= 100) {\n  return new Response(\"Rate limited\", { status: 429 });\n}\nawait env.RATE_LIMITS.put(ipRateKey, String(currentIpCount + 1), { expirationTtl: 120 });\n```\n\n**Per-Route Rate Limiting** (AI endpoints):\n\n```typescript\n// AI routes have stricter limits (e.g., 10 req/min per tenant)\nconst aiRateKey = `ai:${tenantId}:${Math.floor(Date.now() / 60000)}`;\nconst currentAiCount = parseInt((await env.RATE_LIMITS.get(aiRateKey)) || \"0\", 10);\nif (currentAiCount >= 10) {\n  return new Response(\"AI rate limit exceeded\", { status: 429 });\n}\nawait env.RATE_LIMITS.put(aiRateKey, String(currentAiCount + 1), { expirationTtl: 120 });\n```\n\n---\n\n## 12. Deployment Architecture\n\n### 12.1 Frontend Deployment (Cloudflare Pages)\n\n**Automated Deployments** (CI):\n\n```yaml\n# .github/workflows/deploy-frontend.yml\n- All automated deployments go to preview URLs only\n- Preview URLs: https://<hash>.integratewise.pages.dev\n- Production promotion: Manual by Nirmal via Cloudflare dashboard\n- Production URL: https://app.integratewise.ai\n```\n\n**Environment Variables**:\n\n```bash\nVITE_API_BASE_URL=https://gateway.integratewise.ai\nVITE_SPINE_URL=https://<project>.spineDb.co\nVITE_SPINE_ANON_KEY=<anon_key>\n```\n\n### 12.2 Worker Deployment (Cloudflare Workers)\n\n**Automated Deployments** (CI):\n\n```yaml\n# .github/workflows/deploy-workers.yml\n- Workers deploy to production via: wrangler deploy --env production\n- Allowed from CI only for services listed in deploy-workers.yml\n- Never deploy workers without explicit instruction from Nirmal\n- Always run: unset CLOUDFLARE_API_TOKEN before wrangler commands\n- OAuth session (connect@integratewise.ai) is the correct auth\n```\n\n**Service Bindings** (wrangler.toml):\n\n```toml\n[[services]]\nbinding = \"CONNECTOR\"\nservice = \"integratewise-connector\"\n\n[[services]]\nbinding = \"PIPELINE\"\nservice = \"integratewise-pipeline\"\n\n[[services]]\nbinding = \"INTELLIGENCE\"\nservice = \"integratewise-intelligence\"\n\n[[services]]\nbinding = \"KNOWLEDGE\"\nservice = \"integratewise-knowledge\"\n\n[[services]]\nbinding = \"BFF\"\nservice = \"integratewise-bff\"\n\n[[services]]\nbinding = \"L2\"\nservice = \"integratewise-l2\"\n```\n\n---\n\n## 13. Key Takeaways\n\n### 13.1 What Makes This Architecture Unique\n\n1. **Schema-Driven Extraction** — No placeholders, no guessing. Only entity types defined in `tenant_spine_config` are extracted.\n\n2. **8-Stage Normalization** — Every record passes through the same pipeline, ensuring consistent quality and structure.\n\n3. **Fortress Pattern** — Pipeline is the ONLY service with Spine write credentials. No service bypasses the normalizer.\n\n4. **HITL Gating** — High-risk actions (merge, execute) require human approval. No auto-merge, no auto-execute.\n\n5. **Sanity Checks** — Records with score <70 are quarantined, not written to Spine. Quality enforcement at the data plane.\n\n6. **Identity Resolution** — Detects potential duplicates across sources, creates `merge_candidate` records for HITL review. Never auto-merges.\n\n7. **Projection-Based Entitlement** — Navigation and module access driven by projection service, not hardcoded roles.\n\n8. **Density Gating** — Modules only render when sufficient data is available. No empty states for missing data.\n\n9. **Gateway-Only Entry** — All requests go through Gateway. No service can be reached directly.\n\n10. **Circuit Breaker Pattern** — Resilient service-to-service communication with automatic fallback and recovery.\n\n### 13.2 Critical Implementation Details\n\n**Schema Resolution Happens at S1**:\n\n- Loader reads `tenant_spine_config` before extraction\n- S1 Analyze stage resolves both legacy adaptive schema and new schema-driven schema\n- Schema flows through all 8 stages as `_resolved_schema` and `_schema` in payload\n\n**No Auto-Merge Policy**:\n\n- S7.5 Identity Resolution creates `merge_candidate` records\n- Merge candidates require HITL approval via `/api/v1/cognitive/hitl/queue`\n- No automatic merging of cross-source duplicates\n\n**Sanity Score Threshold**:\n\n- S7 Sanity stage calculates score (0-100)\n- Records with score <70 are quarantined (not written to Spine)\n- High-value entities (>$100k) get AI-powered sanity check via OpenRouter\n\n**Quarantine Pattern**:\n\n- Failed records written to `pipeline_quarantine` table\n- Includes: stage, reason_code, reason_detail, payload, metadata\n- Non-blocking — quarantine write failure never blocks pipeline\n\n**Spine Target Resolution**:\n\n- `getSpineTarget(entityType)` returns `{ schema, table, pk }`\n- Example: `account` → `{ schema: \"account_success\", table: \"accounts\", pk: \"account_id\" }`\n- Fallback to `public.entities` if no domain-specific table exists\n\n**Downstream Enqueues**:\n\n- `KNOWLEDGE_QUEUE` — Unstructured content for embedding (Flow B)\n- `ACCELERATOR_QUEUE` — Pre-computed metrics and aggregations\n- `INTELLIGENCE_QUEUE` — Signal processing for Think service\n- `SIGNAL_QUEUE` — Real-time signal broadcast (optional)\n\n---\n\n## 14.

Conclusion\n\nThis deep code analysis confirms that IntegrateWise implements a **production-grade, schema-driven, HITL-gated, sanity-checked** data architecture. The system enforces strict quality controls at every layer:\n\n- **Gateway** validates JWT and injects tenant context\n- **Loader** extracts only schema-defined entity types\n- **Normalizer** enforces 8-stage quality pipeline\n- **Pipeline** is the ONLY Spine writer (fortress pattern)\n- **Spine** stores canonical truth in domain-specific schemas\n\nThe architecture is designed for **compounding value** — every record that passes through the normalizer becomes higher-quality canonical truth, enabling downstream AI/ML features (Think, Act, Govern, Twin) to operate on clean, structured data.\n\n**No shortcuts. No placeholders. No auto-merge. No bypass.**\n\nThis is the foundation for a Knowledge Workspace that compounds in value over time.\n\n---\n\n**Document Version**: 1.0  \n**Last Updated**: 2026-05-29  \n**Author**: Kiro (Deep Code Analysis)  \n**Review Status**: Ready for Nirmal Review\n"}
