Deep Code Analysis: Complete System Flow

IntegrateWise Live — From Frontend to Spine SSOT

Analysis Date: 2026-05-29
Analysis Type: Deep implementation code review (not documentation)
Scope: Complete data flow from app.integratewise.ai through Gateway, Services, 8-Stage Normalizer, to Spine

Executive Summary

This document traces the actual implementation of the complete data flow in IntegrateWise, from user interaction in the React frontend through the Gateway Worker, service layer, 8-stage normalization pipeline, to the canonical Spine in Spine DB PostgreSQL.

Key Finding: The system implements a schema-driven, HITL-gated, sanity-checked architecture where:

Gateway is the ONLY entry point (no service bypass)
Pipeline is the ONLY Spine writer (fortress pattern)
Schema drives extraction (no placeholders, no guessing)
HITL gates high-risk actions (no auto-merge, no auto-execute)
Sanity checks enforce quality (score ≥70 required for Spine write)

1. Frontend Layer: React SPA at `app.integratewise.ai`

1.1 Authentication Flow (AppShell.tsx)

File: /Users/nirmal/Github/integratewise-live/apps/web/src/AppShell.tsx

// Provider Stack (outermost → innermost):
ErrorBoundary → AuthProvider → SpineProvider → GoalProvider →
HydrationFabric → WorkspaceShellNew

// Stage Flow:
login → signup → provisioning → onboarding (L0) → loading → workspace (L1)

Auth Implementation:

Spine DB PKCE with Google SSO, GitHub SSO, email/password
Session Restore: Auto-detects returning users via user_metadata.onboarding_complete
Tenant Provisioning: Refreshes session until app_metadata.tenant_id appears (DB trigger writes it)
Onboarding Gate: New users go through 6-step OnboardingFlow before workspace access

API Client Initialization (api-client.ts):

initApiClient({
  getAccessToken: () => authRef.current.accessToken,
  getTenantId: () => user?.user_metadata?.tenant_id || user?.app_metadata?.tenant_id,
  getUserId: () => authRef.current.user?.id,
  getViewContext: () => resolveViewContext(domain, department),
});

Headers Injected on Every Request:

Authorization: Bearer <JWT> — Spine DB session token
x-tenant-id — Tenant isolation
x-user-id — OAuth state binding + connector callback
x-view-context — Active workspace domain (CTX_CS, CTX_SALES, etc.)
x-idempotency-key — Write operation deduplication
x-approval-token — Act operation authorization

1.2 Workspace Architecture (workspace-shell-new.tsx)

File: /Users/nirmal/Github/integratewise-live/apps/web/src/components/l1/workspace/workspace-shell-new.tsx

Layout Structure:

┌─────────────────────────────────────────────────────────────┐
│ Sidebar (260px)                                             │
│  - Logo + Workspace Selector                                │
│  - Navigation (projection-based or product-based)           │
│  - Settings + Logout                                        │
├─────────────────────────────────────────────────────────────┤
│ Main Content Area                                           │
│  - Header (tabs: Personal | Work)                           │
│  - ContentRouter (lazy-loaded modules)                      │
│  - L2 Cognitive Drawer (⌘J, bottom overlay)                 │
└─────────────────────────────────────────────────────────────┘

View Hierarchy:

Personal View: Same for all users (tasks, calendar, notes)
Work View: Domain-specific (12 domains: CS, Sales, RevOps, Marketing, etc.)
Team View: Org-level collaboration (presence, activity feeds)

Navigation Priority:

Projection-native (from projection service — entitlement-driven)
Product-based (from tenant_products + product_nav_items tables)
Domain fallback (hardcoded workspace-config.ts)

Scoped Slot Loading (Hydration Fabric):

// PERSONAL view: Loads only personal slots
const personalSlots = useScopedSlots("personal");
// {tasks, calendar, notes, dashboard}

// WORK view: Loads domain-specific work slots
const workSlots = useScopedSlots("work");
// {signals, entities, knowledge, goals, connectors}

// TEAM view: Loads org-level collaboration data
const teamSlots = useScopedSlots("team");
// {team.presence, team.activity}

1.3 Content Routing (content-router.tsx)

File: /Users/nirmal/Github/integratewise-live/apps/web/src/components/l1/workspace/content-router.tsx

Module Registry Pattern:

const DOMAIN_CONTENT_MAP: Record<Domain, Record<string, () => Promise<any>>> = {
  CUSTOMER_SUCCESS: CS_MAP,
  SALES: SALES_MAP,
  MARKETING: MARKETING_MAP,
  REVOPS: REVOPS_MAP,
  PRODUCT_ENGINEERING: PE_MAP,
  FINANCE: FINANCE_MAP,
  SERVICE: SERVICE_MAP,
  PROCUREMENT: PROCUREMENT_MAP,
  IT_ADMIN: IT_ADMIN_MAP,
  STUDENT_TEACHER: STUDENT_TEACHER_MAP,
  BIZOPS: buildBizOpsMap(), // Super-domain with cross-department access
  PERSONAL: PERSONAL_MAP,
};

Lazy Loading with Error Boundaries:

const LazyComponent = getLazyComponent(cacheKey, componentLoader);

<ModuleErrorBoundary moduleId={moduleId}>
  <Suspense fallback={<LoadingSkeleton />}>
    <LazyComponent {...moduleProps} />
  </Suspense>
</ModuleErrorBoundary>

Density Gating (data-driven rendering):

Computes moduleDataContext for active module
Calls shouldRenderModule(dataContext, domain, "default")
Shows <EmptyState> if insufficient data, else renders module

Projection-Based Entitlement Guard:

if (userRole && projectedModules && projectedModules.length > 0) {
  const canAccess =
    userRole === "owner" ||
    userRole === "admin" ||
    projectedModules.some(m => m.id === moduleId || m.path.includes(moduleId));

  if (!canAccess) {
    return <EmptyState message="Not entitled" />;
  }
}

2. API Client Layer: Unified Gateway Interface

File: /Users/nirmal/Github/integratewise-live/apps/web/src/lib/api-client.ts

2.1 Core Fetch Implementation

export async function apiFetch<T = any>(
  path: string,
  options: ApiRequestOptions = {},
  label = "API"
): Promise<T> {
  const url = `${API_BASE}${path}`; // API_BASE = gateway.integratewise.ai

  // Build headers per v3.5 Section 22.3
  const headers: Record<string, string> = { ...options.headers };

  // Auth header (always required unless skipAuth)
  if (!options.skipAuth) {
    const token = _getAccessToken?.();
    if (token) headers["Authorization"] = `Bearer ${token}`;
  }

  // Tenant isolation
  const tenantId = _getTenantId?.();
  if (tenantId) headers["x-tenant-id"] = tenantId;

  // User id (OAuth state binding + connector callback)
  const userId = _getUserId?.();
  if (userId) headers["x-user-id"] = userId;

  // View context (for L1/L2 routes)
  const viewContext = _getViewContext?.();
  if (viewContext) headers["x-view-context"] = viewContext;

  // Idempotency key (for write operations)
  if (options.idempotencyKey) {
    headers["x-idempotency-key"] = options.idempotencyKey;
  }

  // Approval token (for Act operations)
  if (options.approvalToken) {
    headers["x-approval-token"] = options.approvalToken;
  }

  const res = await fetch(url, { method, headers, credentials: "include", body });

  if (!res.ok) throw parseApiError(res);
  return res.json();
}

};

3. Gateway Worker: Single Entry Point (Service ①)

File: /Users/nirmal/Github/integratewise-live/services/gateway/src/index.ts

3.1 Architecture Principle

"The Gateway is the SOLE entry point for ALL requests into the workspace."
— KT Note §5.2

NO BYPASS POLICY:

No service can be reached directly except through Gateway
All service bindings are internal to Gateway only
Webhooks are verified and routed through webhook-ingress

3.2 Routing Table

const ROUTES: [string, RouteTarget][] = [
  ["/api/v1/billing", "INTERNAL_BILLING"],
  ["/api/v1/tenants", "INTERNAL_TENANTS"],
  ["/api/v1/support", "INTERNAL_SUPPORT"],
  ["/api/v1/analytics", "BFF"],
  ["/api/v1/agents", "INTELLIGENCE"],
  ["/api/v1/connectors", "CONNECTOR"],
  ["/api/v1/connector", "CONNECTOR"],
  ["/api/v1/loader", "CONNECTOR"],
  ["/api/v1/pipeline", "PIPELINE"],
  ["/api/v1/intelligence", "INTELLIGENCE"],
  ["/api/v1/cognitive/spine", "PIPELINE"],
  ["/api/v1/cognitive/entity360", "PIPELINE"],
  ["/api/v1/entity360", "PIPELINE"],
  ["/api/v1/identity", "PIPELINE"],
  ["/api/v1/cognitive/evidence", "BFF"],
  ["/api/v1/cognitive/memories", "KNOWLEDGE"],
  ["/api/v1/cognitive/signals", "INTELLIGENCE"],

  ["/webhooks/billing", "INTERNAL_BILLING"],
  ["/webhooks", "WEBHOOK_INGRESS"],
];

3.3 Security Enforcements

IP-Based Edge Throttling:

const ip = request.headers.get("cf-connecting-ip") || "unknown";
const ipRateKey = `ip:${ip}:${Math.floor(Date.now() / 60000)}`;
const currentIpCount = parseInt((await env.RATE_LIMITS.get(ipRateKey)) || "0", 10);
if (currentIpCount >= 100) {
  return new Response("Rate limited", { status: 429 });
}
await env.RATE_LIMITS.put(ipRateKey, String(currentIpCount + 1), { expirationTtl: 120 });

JWT Validation + Tenant Injection:

// Gateway validates JWT and injects trusted headers
function routeRequest(request: Request, env: Env, target: RouteTarget): Promise<Response> {
  const tenantId = getTenantId(request); // from x-tenant-id header

  // Route to service binding with circuit breaker
  const fetcher = env[target] as Fetcher;
  const serviceName = TARGET_TO_SERVICE[target] || String(target);
  return resilientFetch(serviceName, fetcher, request, tenantId);
}

CORS Policy Enforcement:

const allowedOrigins = env.ALLOWED_ORIGINS
  ? env.ALLOWED_ORIGINS.split(",").map((o) => o.trim())
  : [];
const requestOrigin = request.headers.get("Origin") || "";
const corsOrigin = allowedOrigins.includes(requestOrigin) ? requestOrigin : allowedOrigins[0] || "";

// CORS preflight
if (request.method === "OPTIONS") {
  return new Response(null, {
    headers: {
      "Access-Control-Allow-Origin": corsOrigin,
      "Access-Control-Allow-Methods": "GET, POST, PUT, PATCH, DELETE, OPTIONS",
      "Access-Control-Allow-Headers": "Authorization, X-MCP-Key, Content-Type, x-tenant-id, ...",
      "Access-Control-Max-Age": "86400",
    },
  });
}

4. Loader Service: Schema-Driven Extraction

File: /Users/nirmal/Github/integratewise-live/services/loader/src/index.ts

4.1 Architectural Principle

"The SCHEMA drives everything. Only entity types defined in tenant_spine_config
get extracted. No placeholders, no guessing. The schema is the SSOT for what
the user needs — this is what makes IntegrateWise a Knowledge Workspace,
not an ETL tool."

4.2 Schema Resolution

async function getSchemaEntityTypes(
  env: LoaderEnv,
  tenantId: string,
  connector: string
): Promise<string[]> {
  const { neon } = await import("@neondatabase/serverless");
  const sql = neon(env.SPINE_URL);

  const rows = await sql`
    SELECT connector_configs, allowed_entity_types
    FROM tenant_spine_config
    WHERE tenant_id = ${tenantId}
    LIMIT 1
  `;

  if (!rows || rows.length === 0) {
    console.warn(`No spine config for tenant ${tenantId} — cannot determine entity types`);
    return [];
  }

  const config = rows[0] as TenantSpineConfig;

  // Check connector-specific config first
  const connectorConfig = config.connector_configs?.[connector];
  if (connectorConfig?.entityTypes && connectorConfig.entityTypes.length > 0) {
    return connectorConfig.entityTypes;
  }

  // Fallback to tenant-level allowed entity types
  if (config.allowed_entity_types && config.allowed_entity_types.length > 0) {
    return config.allowed_entity_types;
  }

  return [];
}

4.3 Creamy Layer Sync (Phase 1)

POST /internal/creamy — Bounded, schema-driven initial extract for onboarding:

app.post("/internal/creamy", async (c) => {
  const tenantId = c.req.header("x-tenant-id");
  const body = await c.req.json();
  const data = CreamyRequestSchema.parse(body);
  const limit = data.options?.limit || 100;

  // SCHEMA-DRIVEN: Resolve entity types from schema config
  const schemaEntityTypes = await getSchemaEntityTypes(c.env, tenantId, data.connector);
  const requestedTypes = data.entityTypes;

  // Intersect: only extract types that both the request AND schema allow
  const effectiveEntityTypes =
    schemaEntityTypes.length > 0
      ? requestedTypes.filter((t) => schemaEntityTypes.includes(t))
      : requestedTypes;

  if (effectiveEntityTypes.length === 0) {
    return c.json(
      {
        error: "No entity types match the tenant schema configuration",
        requested: requestedTypes,
        allowed: schemaEntityTypes,
      },
      422
    );
  }

  // Create job record
  const jobId = crypto.randomUUID();
  const job: CreamyJob = {
    jobId,
    tenantId,
    connector: data.connector,
    entityTypes: effectiveEntityTypes,
    status: "running",
    progress: { total: limit, processed: 0, percentage: 0 },
    extractedCount: 0,
    createdAt: new Date().toISOString(),
  };

  // Persist job in KV (survives worker eviction)
  await saveJob(c.env, job);

  // Start async processing
  c.executionCtx?.waitUntil?.(
    processCreamyLayer(c.env, job, { ...data, entityTypes: effectiveEntityTypes })
  );

  return c.json({
    jobId,
    status: job.status,
    progress: job.progress,
    entityTypes: effectiveEntityTypes,
  });
});

4.4 Creamy Layer Processing

async function processCreamyLayer(
  env: LoaderEnv,
  job: CreamyJob,
  request: z.infer<typeof CreamyRequestSchema>
): Promise<void> {
  const { connector, entityTypes } = request;
  const limit = request.options?.limit || 100;

  // Token Refresh
  let accessToken: string | null = null;
  try {
    accessToken = await getValidAccessToken(env, job.tenantId, connector);
  } catch (err) {
    if (err instanceof TokenExpiredError) {
      job.status = "failed";
      job.error = "Token expired — user must re-authenticate";
      await saveJob(env, job);
      return;
    }
  }

  // Build connector instance for sync adapter
  const connectorInstance = buildConnectorInstance(accessToken);
  const syncOpts: SyncOptions = { phase: "creamy", limit };

  let extracted: Array<Record<string, any>> = [];

  try {
    const syncResult = await universalSync(connector, connectorInstance, syncOpts);

    if (syncResult.entities.length > 0) {
      // Schema-driven: only keep entities whose type is in the allowed list
      extracted = syncResult.entities
        .filter((e) => entityTypes.includes(e.entity_type))
        .map((e) => ({
          id: e.source_id,
          entity_type: e.entity_type,
          type: e.entity_type,
          name: e.name,
          source: e.source,
          source_id: e.source_id,
          data: e.data,
        }));
    } else {
      // No data from provider — this is legitimate (empty account, new setup).
      // Do NOT generate placeholder records. The workspace shows "no data yet."
      console.log(
        `No data returned from ${connector} for tenant ${job.tenantId}. This is normal for new or empty accounts.`
      );
    }
  } catch (syncErr) {
    // Sync adapter error — log it, don't generate fake records.
    console.error(`Sync adapter error for ${connector}:`, syncErr);
    job.error = syncErr instanceof Error ? syncErr.message : String(syncErr);
  }

  // Send extracted data to Pipeline queue for 8-stage processing
  if (env.PIPELINE_QUEUE && extracted.length > 0) {
    for (const record of extracted) {
      const pipelineMsg: PipelineQueueMessage = {
        message_version: 1,
        stage: "analyze", // Start at Stage 1 (S1)
        source: connector,
        source_type: "loader_creamy",
        tenant_id: job.tenantId,
        payload: {
          ...record,
          _entity_type: record.entity_type || entityTypes[0] || "unknown",
          _source_id: record.id || record.source_id || crypto.randomUUID(),
          _tenant_id: job.tenantId,
        },
        metadata: {
          trace_id: `loader-${job.jobId}-${crypto.randomUUID()}`,
          attempt: 0,
          received_at: new Date().toISOString(),
          extracted_at: new Date().toISOString(),
          loader_job_id: job.jobId,
          phase: "creamy",
        },
      };

      await env.PIPELINE_QUEUE.send(pipelineMsg);
    }
  }

  // Mark job complete
  job.status = "completed";
  job.extractedCount = extracted.length;
  job.completedAt = new Date().toISOString();
  await saveJob(env, job);
}

5. Normalizer Service: 8-Stage Pipeline

File: /Users/nirmal/Github/integratewise-live/services/normalizer/src/index.ts

5.1 The 8 Stages

S1. ANALYZE  - Detect entity type, resolve tenant schema, fingerprint data
S2. CLASSIFY - Assign category, priority, sensitivity level
S3. FILTER   - Tenant/schema filtering, idempotency checks, data age validation
S4. REFINE   - Normalize field names, split composites, extract cross-ref IDs
S5. EXTRACT  - Map to canonical schema, prune non-allowed fields
S6. VALIDATE - Required field checks, type validation, integrity rules
S7. SANITY   - Anomaly detection, business rule validation (score ≥ 70 required)
S8. SECTORIZE- Route to correct Spine table, write truth, enqueue downstream

5.2 Queue Consumer Implementation

  async queue(batch: MessageBatch<PipelineMessage>, env: Env): Promise<void> {
    for (const msg of batch.messages) {
      const payload = msg.body;
      const startTime = Date.now();

      try {
        const result = await processStage(payload, env);

        if (result === null) {
          // Filtered out (Stage 3)
          msg.ack();
          continue;
        }

        // Advance to next stage
        const currentIdx = STAGES.indexOf(payload.stage);
        const nextIdx = currentIdx + 1;

        if (nextIdx < STAGES.length) {
          await env.PIPELINE_QUEUE.send({
            ...result,
            stage: STAGES[nextIdx],
            metadata: { ...result.metadata, attempt: 0 },
          });
        } else {
          // Final stage complete — write to Spine
          if (result.payload._sanity_passed === false) {
            // Sanity check failed — send to DLQ
            await writeQuarantine(
              env,
              result,
              "S7_sanity",
              "sanity_low_confidence",
              `Sanity score ${result.payload._sanity_score}/100`
            );
            await env.DLQ_QUEUE.send({
              ...result,
              error: `Sanity check failed: ${result.payload._sanity_flags?.join(", ")}`,
              failed_at: new Date().toISOString(),
            });
          } else {
            // S7.5 IDENTITY RESOLUTION — detect potential duplicates (never auto-merge)
            await detectPotentialDuplicates(result, env);
            await sectorize(result, env);
          }

6. Pipeline Service: Consolidated Normalizer + Spine

File: /Users/nirmal/Github/integratewise-live/services/pipeline/src/index.ts

6.1 Fortress Pattern

"SECURITY: This is the ONLY service with Spine write credentials.
No other worker may write to the Spine SSOT."

Service Consolidation (v3.6):

Merges: normalizer + spine-v2
Handles: 8-stage pipeline processing + Spine SSOT reads/writes
Queue consumers: pipeline-process, accelerator-trigger

7. Complete Data Flow Summary

7.1 User Action → Spine Write

1. USER ACTION (Frontend)
   ↓
   User clicks "Sync HubSpot" in workspace
   ↓

2. API CLIENT (api-client.ts)
   ↓
   connector.authorize("hubspot")
   → POST /api/v1/connectors/hubspot/authorize
   Headers: Authorization: Bearer <JWT>, x-tenant-id, x-user-id
   ↓

3. GATEWAY (gateway/src/index.ts)
   ↓
   Validates JWT, injects x-tenant-id, routes to CONNECTOR service
   → resilientFetch("integratewise-connector", env.CONNECTOR, request)
   ↓

4. CONNECTOR SERVICE (connector/src/index.ts)
   ↓
   OAuth flow: returns authUrl
   User completes OAuth in browser
   Callback: POST /api/v1/connectors/hubspot/callback?code=...&state=...
   ↓

5. CONNECTOR SERVICE (OAuth Callback)
   ↓
   Exchanges code for access_token + refresh_token
   Writes to Spine DB connectors table (encrypted tokens)
   Triggers creamy sync via LOADER service
   ↓

6. LOADER SERVICE (loader/src/index.ts)
   ↓
   POST /internal/creamy
   Resolves schema: getSchemaEntityTypes(tenantId, "hubspot")
   → Reads tenant_spine_config.connector_configs.hubspot.entityTypes
   Calls universalSync("hubspot", connectorInstance, { phase: "creamy", limit: 100 })
   Filters extracted entities to schema-allowed types only
   Sends to PIPELINE_QUEUE (message_version: 1, stage: "analyze")
   ↓

7. NORMALIZER (8-STAGE PIPELINE)
   ↓
   S1: ANALYZE — Detect entity type, resolve schema
   S2: CLASSIFY — Assign priority
   S3: FILTER — Schema-driven entity type filtering (drops if not in schema)
   S4: REFINE — Normalize field names, apply canonical mapping
   S5: EXTRACT — Prune to schema-allowed fields only
   S6: VALIDATE — Required field checks, type validation
   S7: SANITY — Anomaly detection (score ≥70 required)
   S7.5: IDENTITY RESOLUTION — Detect duplicates (creates merge_candidate, never auto-merges)
   S8: SECTORIZE — Route to correct Spine table
   ↓

8. SPINE WRITE (pipeline/src/index.ts)
   ↓
   Resolves Spine target: getSpineTarget(entityType)
   → Returns { schema: "account_success", table: "accounts", pk: "account_id" }
   Writes to Spine DB: account_success.accounts
   Enqueues downstream: ACCELERATOR_QUEUE, INTELLIGENCE_QUEUE
   ↓

9. SPINE SSOT (Spine DB PostgreSQL)
   ↓
   Canonical truth stored in domain-specific schema
   account_success.accounts, revenue_operations.opportunities, etc.
   ↓

10. FRONTEND REFRESH (Real-time or Polling)
    ↓
    Spine DB Realtime subscription OR polling via pipeline.entities()
    → GET /api/v1/pipeline/entities?type=account
    Gateway → Pipeline → fetchTypedSpineRows()
    Returns normalized entities to frontend
    ContentRouter renders updated data

7.2 Key Architectural Principles Verified

1. Gateway is the ONLY Entry Point

✅ All frontend requests go through gateway.integratewise.ai
✅ No service can be reached directly (service bindings are internal)
✅ JWT validation + tenant injection happens at Gateway only

2. Pipeline is the ONLY Spine Writer (Fortress Pattern)

✅ Pipeline service has exclusive Spine DB credentials
✅ All other services read via Pipeline HTTP API
✅ No service bypasses the 8-stage normalizer

3. Schema Drives Extraction (No Placeholders)

✅ Loader reads tenant_spine_config before extraction
✅ Only schema-defined entity types are extracted
✅ S3 Filter stage drops entities not in schema
✅ S5 Extract stage prunes fields not in schema
✅ No fake/placeholder records generated

4. HITL Gates High-Risk Actions (No Auto-Merge)

✅ S7.5 Identity Resolution creates merge_candidate records
✅ Merge candidates require HITL approval via /api/v1/cognitive/hitl/queue
✅ No automatic merging of cross-source duplicates
✅ Act operations require approval token

5. Sanity Checks Enforce Quality (Score ≥70 Required)

✅ S7 Sanity stage runs rule-based + AI-powered checks
✅ Records with score <70 are quarantined (not written to Spine)
✅ Quarantine records written to pipeline_quarantine table
✅ DLQ captures failed records for manual review

6. Projection-Based Entitlement

✅ ContentRouter checks projectedModules before rendering
✅ Navigation built from projection service (entitlement-driven)
✅ Fallback to product-based nav if projection unavailable

7. Density Gating (Data-Driven Rendering)

✅ shouldRenderModule(dataContext, domain, "default") checks data availability
✅ Shows <EmptyState> if insufficient data
✅ Prevents rendering empty modules

8. Data Schemas and Tables

Frontend Always Calls Gateway:

const API_BASE = import.meta.env.VITE_API_BASE_URL || "";
// Production: https://gateway.integratewise.ai

10. Error Handling and Observability

10.1 Pipeline Error Handling

Retry Strategy:

if (payload.metadata.attempt < 3) {
  msg.retry({ delaySeconds: 30 * (payload.metadata.attempt + 1) });
} else {
  // Max retries — send to DLQ
  await env.DLQ_QUEUE.send({
    ...payload,
    error: errMsg,
    failed_at: new Date().toISOString(),
  });
  msg.ack();
}

Quarantine Pattern:

async function writeQuarantine(
  env: Env,
  msg: PipelineMessage,
  stage: "S3_filter" | "S5_extract" | "S6_validate" | "S7_sanity" | "S8_sectorize",
  reasonCode: QuarantineReasonCode,
  reasonDetail?: string
): Promise<void> {
  const { createClient } = await import("@spineDb/spineDb-js");
  const spineDb = createClient(env.SPINE_URL, env.SPINE_ANON_KEY);
  await spineDb.from("pipeline_quarantine").insert({
    id: crypto.randomUUID(),
    tenant_id: msg.tenant_id,
    provider: msg.source || "unknown",
    entity_type: msg.payload._entity_type || msg.payload.type || null,
    source_id: msg.payload.id || msg.payload.source_id || msg.payload.external_id || null,
    stage,
    reason_code: reasonCode,
    reason_detail: reasonDetail || null,
    payload: stripInternalPayload(msg.payload),
    metadata: {
      trace_id: msg.metadata.trace_id,
      attempt: msg.metadata.attempt,
      source_type: msg.source_type,
    },
    created_at: new Date().toISOString(),
  });
}

10.2 Circuit Breaker Pattern

Gateway Resilient Fetch:

function routeRequest(request: Request, env: Env, target: RouteTarget): Promise<Response> {
  const tenantId = getTenantId(request);
  const fetcher = env[target] as Fetcher;
  const serviceName = TARGET_TO_SERVICE[target] || String(target);
  return resilientFetch(serviceName, fetcher, request, tenantId);
}

// resilientFetch implementation (lib/resilience.ts):
// - Tracks service health per tenant
// - Opens circuit after N consecutive failures
// - Half-open state for gradual recovery
// - Fallback responses for degraded services

10.3 Logging and Tracing

Trace ID Propagation:

const pipelineMsg: PipelineQueueMessage = {
  message_version: 1,
  stage: "analyze",
  source: connector,
  source_type: "loader_creamy",
  tenant_id: job.tenantId,
  payload: { ... },
  metadata: {
    trace_id: `loader-${job.jobId}-${crypto.randomUUID()}`, // Propagates through all 8 stages
    attempt: 0,
    received_at: new Date().toISOString(),
    extracted_at: new Date().toISOString(),
    loader_job_id: job.jobId,
    phase: "creamy",
  },
};

Pipeline Step Logging:

async function logPipelineStep(
  env: Env,
  msg: PipelineMessage,
  status: "completed" | "failed",
  durationMs: number,
  error?: string
): Promise<void> {
  // Log to D1 or KV for observability
  // Includes: trace_id, stage, tenant_id, entity_type, status, duration, error
}

11. Security Model

11.1 Authentication Flow

Spine DB PKCE (Proof Key for Code Exchange):

// 1. User initiates login
await auth.signIn(email, password);

// 2. Spine DB returns JWT with user_metadata
const user = {
  id: "uuid",
  email: "user@example.com",
  user_metadata: {
    name: "John Doe",
    tenant_id: "tenant-uuid", // Set by DB trigger after signup
  },
  app_metadata: {
    tenant_id: "tenant-uuid", // Also in app_metadata for redundancy
  },
};

// 3. Frontend stores JWT in memory (not localStorage)
// 4. Every API call includes: Authorization: Bearer <JWT>

OAuth Flow (Google, GitHub):

// 1. User clicks "Sign in with Google"
await auth.signInWithGoogle();

// 2. Spine DB redirects to Google OAuth
// 3. User approves, Google redirects back with code
// 4. Spine DB exchanges code for JWT
// 5. Frontend receives JWT with user_metadata
// 6. Provisioning loop waits for tenant_id to appear in JWT

11.2 Tenant Isolation

Row-Level Security (RLS) in Spine DB:

-- All Spine tables have RLS enabled
CREATE POLICY "tenant_isolation" ON account_success.accounts
  FOR ALL
  USING (tenant_id = current_setting('request.jwt.claims')::json->>'tenant_id');

-- Gateway injects x-tenant-id header
-- Spine DB client uses it for RLS enforcement
const spineDb = createClient(env.SPINE_URL, env.SPINE_ANON_KEY, {
  global: { headers: { "x-tenant-id": tenantId } },
  db: { schema },
});

Service-Level Isolation:

// Every service binding call includes tenant context
function routeRequest(request: Request, env: Env, target: RouteTarget): Promise<Response> {
  const tenantId = getTenantId(request); // from x-tenant-id header
  const fetcher = env[target] as Fetcher;
  return resilientFetch(serviceName, fetcher, request, tenantId);
}

11.3 Rate Limiting

IP-Based Edge Throttling:

const ip = request.headers.get("cf-connecting-ip") || "unknown";
const ipRateKey = `ip:${ip}:${Math.floor(Date.now() / 60000)}`;
const currentIpCount = parseInt((await env.RATE_LIMITS.get(ipRateKey)) || "0", 10);
if (currentIpCount >= 100) {
  return new Response("Rate limited", { status: 429 });
}
await env.RATE_LIMITS.put(ipRateKey, String(currentIpCount + 1), { expirationTtl: 120 });

Per-Route Rate Limiting (AI endpoints):

// AI routes have stricter limits (e.g., 10 req/min per tenant)
const aiRateKey = `ai:${tenantId}:${Math.floor(Date.now() / 60000)}`;
const currentAiCount = parseInt((await env.RATE_LIMITS.get(aiRateKey)) || "0", 10);
if (currentAiCount >= 10) {
  return new Response("AI rate limit exceeded", { status: 429 });
}
await env.RATE_LIMITS.put(aiRateKey, String(currentAiCount + 1), { expirationTtl: 120 });

12. Deployment Architecture

12.1 Frontend Deployment (Cloudflare Pages)

Automated Deployments (CI):

# .github/workflows/deploy-frontend.yml
- All automated deployments go to preview URLs only
- Preview URLs: https://<hash>.integratewise.pages.dev
- Production promotion: Manual by Nirmal via Cloudflare dashboard
- Production URL: https://app.integratewise.ai

Environment Variables:

VITE_API_BASE_URL=https://gateway.integratewise.ai
VITE_SPINE_URL=https://<project>.spineDb.co
VITE_SPINE_ANON_KEY=<anon_key>

12.2 Worker Deployment (Cloudflare Workers)

Automated Deployments (CI):

# .github/workflows/deploy-workers.yml
- Workers deploy to production via: wrangler deploy --env production
- Allowed from CI only for services listed in deploy-workers.yml
- Never deploy workers without explicit instruction from Nirmal

- OAuth session (connect@integratewise.ai) is the correct auth

Service Bindings (wrangler.toml):

[[services]]
binding = "CONNECTOR"
service = "integratewise-connector"

[[services]]
binding = "PIPELINE"
service = "integratewise-pipeline"

[[services]]
binding = "INTELLIGENCE"
service = "integratewise-intelligence"

[[services]]
binding = "L2"
service = "integratewise-l2"

13. Key Takeaways

13.1 What Makes This Architecture Unique

Schema-Driven Extraction — No placeholders, no guessing. Only entity types defined in tenant_spine_config are extracted.
8-Stage Normalization — Every record passes through the same pipeline, ensuring consistent quality and structure.
Fortress Pattern — Pipeline is the ONLY service with Spine write credentials. No service bypasses the normalizer.
HITL Gating — High-risk actions (merge, execute) require human approval. No auto-merge, no auto-execute.
Sanity Checks — Records with score <70 are quarantined, not written to Spine. Quality enforcement at the data plane.
Identity Resolution — Detects potential duplicates across sources, creates merge_candidate records for HITL review. Never auto-merges.
Projection-Based Entitlement — Navigation and module access driven by projection service, not hardcoded roles.
Density Gating — Modules only render when sufficient data is available. No empty states for missing data.
Gateway-Only Entry — All requests go through Gateway. No service can be reached directly.
Circuit Breaker Pattern — Resilient service-to-service communication with automatic fallback and recovery.

13.2 Critical Implementation Details

Schema Resolution Happens at S1:

Loader reads tenant_spine_config before extraction
S1 Analyze stage resolves both legacy adaptive schema and new schema-driven schema
Schema flows through all 8 stages as _resolved_schema and _schema in payload

No Auto-Merge Policy:

S7.5 Identity Resolution creates merge_candidate records
Merge candidates require HITL approval via /api/v1/cognitive/hitl/queue
No automatic merging of cross-source duplicates

Sanity Score Threshold:

S7 Sanity stage calculates score (0-100)
Records with score <70 are quarantined (not written to Spine)
High-value entities (>$100k) get AI-powered sanity check via OpenRouter

Quarantine Pattern:

Failed records written to pipeline_quarantine table
Includes: stage, reason_code, reason_detail, payload, metadata
Non-blocking — quarantine write failure never blocks pipeline

Spine Target Resolution:

getSpineTarget(entityType) returns { schema, table, pk }
Example: account → { schema: "account_success", table: "accounts", pk: "account_id" }
Fallback to public.entities if no domain-specific table exists

Downstream Enqueues:

KNOWLEDGE_QUEUE — Unstructured content for embedding (Flow B)
ACCELERATOR_QUEUE — Pre-computed metrics and aggregations
INTELLIGENCE_QUEUE — Signal processing for Think service
SIGNAL_QUEUE — Real-time signal broadcast (optional)

15. Conclusion

This 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:

Gateway validates JWT and injects tenant context
Loader extracts only schema-defined entity types
Normalizer enforces 8-stage quality pipeline
Pipeline is the ONLY Spine writer (fortress pattern)
Spine stores canonical truth in domain-specific schemas

The 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.

No shortcuts. No placeholders. No auto-merge. No bypass.

This is the foundation for a Knowledge Workspace that compounds in value over time.
