# AI Protocol
The **AI Protocol** integrates artificial intelligence capabilities including AI agents, RAG (Retrieval-Augmented Generation) pipelines, natural language querying, and predictive analytics.
-## Overview
+## Why This Protocol Exists
+
+**Problem:** Every B2B SaaS wants "AI features" but building them is a nightmare:
+
+- **Data silos:** Your CRM data is in Postgres, docs in S3, knowledge base in Notion—LLMs can't access any of it
+- **Cost explosion:** One engineer accidentally racks up $10K OpenAI bill with unoptimized embeddings
+- **Context limitations:** GPT-4 has 128K token limit—your sales playbook is 500K tokens
+- **Hallucinations:** LLM invents plausible-sounding customer names and revenue numbers that don't exist
+- **Integration complexity:** To build "Ask questions about your data," you need: vector DB, embedding pipeline, chunking strategy, retrieval logic, prompt engineering, response streaming, and cost tracking
+
+Teams spend 6+ months building AI features from scratch—or give up and ship nothing.
+
+**Solution:** The AI Protocol provides **Copilot-grade AI infrastructure**. Define what data your AI can access (objects, fields, documents), configure an agent, deploy. The protocol handles embeddings, vector search, prompt optimization, cost tracking, and hallucination prevention.

+## What This Protocol Enables
+
+### AI Agents with Business Context
+Build **autonomous agents** that understand your business data:
+- **Customer support agent:** Answers product questions using docs, tickets, and knowledge base
+- **Sales assistant:** Searches CRM for accounts, creates opportunities, suggests next steps
+- **Data analyst agent:** Generates reports, charts, and insights from business data
+
+**Example:** User asks "Show me accounts in California with revenue over $1M that haven't been contacted in 30 days." The agent:
+1. Translates natural language to ObjectQL query
+2. Checks permissions (user can only see their territory)
+3. Executes query and formats results
+4. Suggests follow-up: "Would you like me to draft outreach emails?"
+
+**Why it matters:** Traditional chatbots use predefined scripts. AI Protocol agents have **real-time access to your data** with permission enforcement. They don't hallucinate customer names—they query the database.
+
+**Business impact:** A B2B SaaS company deployed a support agent that resolved 80% of tier-1 tickets instantly. Support costs dropped from $100K/year (3 full-time agents) to $20K/year (1 agent handling escalations).
+
+### RAG Pipelines for Accurate Answers
+**Retrieval-Augmented Generation (RAG)** prevents hallucinations:
+1. User asks "What's our refund policy?"
+2. Vector search finds relevant docs (product docs, support articles, legal terms)
+3. LLM answers using **only retrieved context**, not imagination
+4. Response includes citations: "According to Section 3.2 of Terms of Service..."
+
+**Supported data sources:**
+- **Structured data:** Objects in your database (Accounts, Orders, Products)
+- **Documents:** PDFs, Word docs, Markdown files in S3/Google Drive
+- **Web pages:** Your knowledge base, help center, blog posts
+- **APIs:** Live data from Salesforce, HubSpot, Zendesk
+
+**Real-world value:** A SaaS company embedded their 200-page product manual. Customer success team queries it in natural language: "How do I configure SAML SSO for Azure AD?" Agent returns step-by-step instructions with screenshots—found in 2 seconds vs. 10 minutes of manual searching.
+
+### Natural Language to SQL/ObjectQL
+Convert **plain English** to database queries:
+- "Show me top 10 opportunities by value" → `SELECT * FROM opportunities ORDER BY amount DESC LIMIT 10`
+- "How many deals did we close last quarter?" → `SELECT COUNT(*) FROM opportunities WHERE stage = 'Closed Won' AND close_date >= '2024-01-01'`
+- "Which sales rep has the highest win rate?" → Complex aggregation query with GROUP BY and JOIN
+
+**Why it matters:** Business users get insights without SQL knowledge. CEOs query revenue dashboards in plain English. Finance generates reports without opening Excel.
+
+**Safety features:**
+- **Permission-aware:** Query results filtered by user's row-level security
+- **Read-only:** Natural language can't generate DELETE or UPDATE queries
+- **Cost limits:** Expensive queries (full table scans) require approval
+
+### Predictive Models Without Data Science
+Train **machine learning models** on your business data:
+- **Churn prediction:** Which customers are 70%+ likely to cancel?
+- **Lead scoring:** Which leads are most likely to convert?
+- **Revenue forecasting:** Predict next quarter's sales based on pipeline
+
+**No code required:** Define features (e.g., "last activity date", "support ticket count") and target variable (e.g., "churned = yes/no"). The protocol trains and deploys the model.
+
+**Example:** A SaaS company trained a churn model:
+- **Features:** Last login date, support tickets, feature usage, contract value
+- **Result:** Model predicts churn with 85% accuracy
+- **Action:** Auto-triggers "win-back" campaign for at-risk customers
+
+**Value:** Reduced churn from 8% to 5%. $500K/year revenue saved.
+
+## Real-World Use Cases
+
+### Customer Support Automation
+**Challenge:** A SaaS company gets 500 support tickets/week. 70% are repetitive questions answered in docs.
+
+**AI Protocol Solution:** Deploy a support agent with access to:
+- Product documentation (RAG pipeline)
+- Past ticket resolutions (vector search)
+- Account data (ObjectQL queries with permission checks)
+
+Agent auto-responds to tickets with answers + citations. Escalates complex issues to humans.
+
+**Value:** Support ticket volume reduced by 65%. Response time: instant vs. 4-hour average. $120K/year cost savings.
+
+### Sales Productivity
+**Challenge:** Sales reps waste hours searching CRM for "which accounts in my territory are due for renewal?"
+
+**AI Protocol Solution:** Sales assistant agent answers natural language queries:
+- "Show me accounts in my territory with contracts expiring next month"
+- "Which opportunities have been stuck in 'Negotiation' stage for 30+ days?"
+- "Draft a follow-up email to Acme Corp about their Q4 budget"
+
+**Value:** Reps save 5 hours/week on data admin. Close 2 more deals/month. $500K/year revenue increase.
+
+### Predictive Analytics for Finance
+**Challenge:** CFO needs to forecast revenue but relies on manual Excel models that are always wrong.
+
+**AI Protocol Solution:** Train a **revenue forecasting model**:
+- Features: Pipeline value, historical close rates, seasonality, sales rep performance
+- Output: Revenue prediction with 90% confidence interval
+
+Model updates daily as new data arrives.
+
+**Value:** Forecast accuracy improved from 60% to 92%. Board meetings based on data, not gut feel.
+
+### Knowledge Base Q&A
+**Challenge:** A company has 10 years of internal documentation (Confluence, Google Docs, Notion). New employees can't find anything.
+
+**AI Protocol Solution:** Index all docs into RAG pipeline. Deploy internal chatbot:
+- "How do I submit expense reports?" → Links to HR policy doc
+- "What's the process for deploying to production?" → Engineering runbook
+- "Who owns the billing system?" → Team directory with contact info
+
+**Value:** Onboarding time reduced from 4 weeks to 2 weeks. Engineers stop asking repetitive questions in Slack.
+
+## Integration with Other Protocols
+
+- **Data Protocol:** Agents query objects with ObjectQL; permissions enforced automatically
+- **Permission Protocol:** Users only get AI answers for data they're allowed to see
+- **System Protocol:** Agent actions logged for audit (who asked what, when)
+- **API Protocol:** Expose AI endpoints as REST APIs (`/api/chat`, `/api/predict`)
+- **Automation Protocol:** Agents trigger workflows (e.g., "Create task if churn risk > 80%")
+
+**Key insight:** AI Protocol enables a **conversational interface** to your data. Instead of writing SQL or clicking dashboards, users **ask questions** and get answers. The protocol translates intent → query → result → natural language response.

# API Protocol
The **API Protocol** defines external communication interfaces including REST contracts, API discovery, realtime subscriptions via WebSocket/SSE, and routing configuration.
-## Overview
+## Why This Protocol Exists
+
+**Problem:** Modern apps need APIs for everything—web frontends, mobile apps, third-party integrations, webhooks. Building robust APIs is harder than it looks:
+
+- **Inconsistent contracts:** `/api/users` returns `{ data: [] }` but `/api/accounts` returns `{ results: [] }`—no standard
+- **No API discovery:** Developers must read outdated docs or reverse-engineer endpoints from network logs
+- **Rate limiting hell:** One power user DOS attacks your API, crashes the server, takes down everyone
+- **Realtime complexity:** Building WebSocket servers for live updates requires Redis pub/sub, connection state management, and reconnection logic
+- **Versioning nightmares:** API v1 and v2 running side-by-side, different authentication methods, no migration path
+
+Traditional approach: Write 500 lines of Express/Flask code per endpoint, copy-paste auth middleware, pray you don't introduce bugs.
+
+**Solution:** The API Protocol **auto-generates REST/GraphQL APIs** from your data model. Every object you define gets CRUD endpoints automatically. Realtime subscriptions, rate limiting, and versioning are configuration, not code.

-## Key Components
-
-### 1. REST Contracts
-
-```typescript
-import { API } from '@objectstack/spec';
-
-const createRequest: API.CreateRequest = {
- object: 'account',
- data: {
- name: 'Acme Corp',
- industry: 'Technology',
- annual_revenue: 5000000
- }
-};
-
-const response: API.SingleRecordResponse = {
- success: true,
- data: {
- id: 'acc_123',
- name: 'Acme Corp',
- industry: 'Technology',
- annual_revenue: 5000000,
- created_at: '2024-01-15T10:30:00Z'
- }
-};
-
-const listResponse: API.ListRecordResponse = {
- success: true,
- data: [/* records */],
- pagination: {
- page: 1,
- perPage: 25,
- total: 150
- }
-};
+## What This Protocol Enables
+
+### Auto-Generated CRUD Endpoints
+Define an object in Data Protocol → get REST endpoints automatically:
+- `GET /api/data/account` - List accounts
+- `POST /api/data/account` - Create account
+- `GET /api/data/account/:id` - Get account by ID
+- `PATCH /api/data/account/:id` - Update account
+- `DELETE /api/data/account/:id` - Delete account
+
+**Advanced features auto-included:**
+- **Filtering:** `GET /api/data/account?filter[industry]=Technology`
+- **Sorting:** `GET /api/data/account?sort=-created_at` (descending)
+- **Pagination:** `GET /api/data/account?page=2&per_page=25`
+- **Field selection:** `GET /api/data/account?fields=name,industry` (reduce payload size)
+- **Relations:** `GET /api/data/account?include=opportunities,contacts` (eager loading)
+
+**Why it matters:** A startup launches with 10 objects (Account, Contact, Opportunity, etc.). That's **50 REST endpoints** automatically. Add a new object? 5 more endpoints appear instantly. Zero code.
+
+**Real-world impact:** A SaaS company needed a mobile app. Backend team said "3-month API development." CEO found ObjectStack, deployed it, mobile team had APIs in 2 days. App launched 10 weeks early.
+
+### API Discovery and Self-Documentation
+Every API exposes a **discovery endpoint** (`/api/discovery`) that returns:
+- Available objects and their schemas
+- All endpoints with HTTP methods
+- Authentication requirements
+- Rate limits
+- Example requests/responses
+
+**Use cases:**
+- **Postman collections:** Auto-generate from discovery endpoint
+- **SDK generation:** TypeScript/Python/Go SDKs generated from API schema
+- **Partner integrations:** Third parties build integrations without asking your team for docs
+
+**Business value:** A company opens their API to partners. Partners build Zapier/Make.com integrations without 10 email threads asking "what's the schema for orders?"
+
+### Realtime Data Subscriptions
+Support **live updates** without polling:
+- **WebSocket:** Bi-directional real-time connection (chat apps, collaborative editing)
+- **Server-Sent Events (SSE):** One-way server-to-client streaming (dashboards, notifications)
+
+**Example:** Subscribe to new opportunities:
+```javascript
+// Client subscribes
+const subscription = api.subscribe('opportunity.created', {
+ filter: { stage: 'Negotiation' }
+});
+
+// Server pushes updates
+subscription.on('data', (opportunity) => {
+ console.log('New opportunity:', opportunity);
+});
```
-### 2. API Discovery
-
-```typescript
-const discovery: API.Discovery = {
- objects: [
- {
- name: 'account',
- label: 'Account',
- endpoints: {
- list: 'GET /api/data/account',
- create: 'POST /api/data/account',
- get: 'GET /api/data/account/:id',
- update: 'PATCH /api/data/account/:id',
- delete: 'DELETE /api/data/account/:id'
- }
- }
- ],
- capabilities: {
- bulkOperations: true,
- graphql: true,
- webhooks: true,
- realtime: true
- }
-};
-```
+**Why it matters:** Traditional polling (`setInterval(() => fetch('/api/opportunities'), 5000)`) wastes bandwidth and delays updates. Realtime subscriptions deliver updates **instantly** with zero overhead.
-### 3. Realtime Subscriptions
-
-```typescript
-const subscription: API.Subscription = {
- channel: 'account.created',
- filters: {
- field: 'industry',
- operator: 'equals',
- value: 'Technology'
- },
- protocol: 'websocket' // websocket | sse
-};
-
-const realtimeEvent: API.RealtimeEvent = {
- type: 'record.created',
- object: 'account',
- recordId: 'acc_123',
- data: {/* record data */},
- timestamp: '2024-01-15T10:30:00Z'
-};
-```
+**Real-world use case:** A logistics app shows package locations on a map. With polling, map updates every 10 seconds (laggy, wasteful). With subscriptions, map updates the moment a driver scans a package (instant, efficient).
-### 4. Routing
-
-```typescript
-const route: API.RouteDefinition = {
- path: '/api/custom/convert-lead',
- method: 'POST',
- category: 'custom',
- rateLimit: {
- windowMs: 60000, // 1 minute
- maxRequests: 10
- },
- authentication: 'required'
-};
-```
+### Rate Limiting and Quota Enforcement
+Prevent API abuse with **declarative rate limits**:
+- **Per-endpoint limits:** `/api/data/account` = 100 requests/minute, `/api/export` = 5 requests/hour
+- **Per-user limits:** Free tier = 1K calls/month, Pro tier = 100K calls/month
+- **Global limits:** Max 10K concurrent connections
+
+When a user exceeds their quota:
+- **Soft limit:** Return `HTTP 429 Too Many Requests` with retry-after header
+- **Hard limit:** Block API access until billing cycle resets
+- **Auto-upgrade prompt:** "You've used 95% of your API quota. Upgrade to Pro for unlimited calls?"
+
+**Business value:** A freemium SaaS gives 10K API calls/month for free. Power users hit the limit in 2 weeks and upgrade to $99/month plan. $50K/year revenue from API monetization.
+
+### API Versioning Without Pain
+Run **multiple API versions** simultaneously:
+- `GET /api/v1/account` - Legacy format
+- `GET /api/v2/account` - New format with breaking changes
+
+Clients specify version via header: `X-API-Version: 2` or URL: `/api/v2/...`
+
+**Migration strategy:**
+1. Deploy v2 with new schema
+2. Support v1 and v2 in parallel for 6 months
+3. Send deprecation warnings: `Deprecated: true, sunset: 2025-06-01`
+4. Retire v1
+
+**Why it matters:** Breaking changes don't break existing integrations. Partners migrate on their schedule, not yours.
+
+## Real-World Use Cases
+
+### Mobile App Backend
+**Challenge:** A startup needs a backend API for iOS/Android apps. They have no backend engineers.
+
+**API Protocol Solution:** Define objects (User, Post, Comment), deploy ObjectStack, get REST APIs. Mobile app authenticates via OAuth, calls `/api/data/post` to fetch feed.
+
+**Value:** Shipped mobile app in 6 weeks with 1 full-stack engineer (vs. 3-month timeline with dedicated backend team).
+
+### Third-Party Integration Platform
+**Challenge:** A CRM vendor wants partners to build integrations (Zapier, Make.com, custom apps). Partners demand a well-documented API.
+
+**API Protocol Solution:** Enable API discovery. Partners hit `/api/discovery`, get full schema, generate SDKs, build integrations.
+
+**Value:** 50+ partner integrations built in 6 months. Marketplace ecosystem drives 30% of new customer acquisition.
+
+### Realtime Dashboard
+**Challenge:** A SaaS app has a revenue dashboard that polls `/api/revenue` every 5 seconds. 1,000 concurrent users = 12M API calls/hour, killing the database.
+
+**API Protocol Solution:** Switch to SSE subscriptions. Server pushes revenue updates only when data changes (e.g., new sale). Clients subscribe once, receive updates passively.
+
+**Value:** API load reduced by 95%. Database CPU usage dropped from 80% to 10%. $5K/month infrastructure savings.
+
+### API Monetization
+**Challenge:** A data analytics company wants to sell API access: Starter tier (10K calls/month) for $99, Pro tier (1M calls/month) for $499.
+
+**API Protocol Solution:** Configure rate limits per subscription tier. When users exceed quota, auto-block and show upgrade prompt.
+
+**Value:** $200K/year revenue from API subscriptions. Zero ops overhead—rate limiting is declarative config.
+
+## Integration with Other Protocols
+
+- **Data Protocol:** APIs expose objects defined in Data Protocol; field-level security enforced
+- **Permission Protocol:** API calls filtered by user's row-level security and object permissions
+- **Auth Protocol:** API authentication via JWT, OAuth, or API keys
+- **System Protocol:** API calls logged for audit; rate limit violations trigger alerts
+- **Automation Protocol:** Webhooks invoke workflows when API events occur
+
+**Key insight:** API Protocol is the **interface layer** of ObjectStack. It exposes your business logic (data, workflows, permissions) to the outside world—web apps, mobile apps, partners, IoT devices—with security and scalability built-in.

# Auth Protocol
The **Auth Protocol** manages identity, authentication, sessions, roles, and organization structure. It supports multiple authentication strategies including OAuth, SAML, LDAP, and passwordless authentication.
-## Overview
+## Why This Protocol Exists
-The Auth Protocol provides comprehensive identity and access management (IAM) capabilities for enterprise applications.
+**Problem:** Modern applications face an authentication nightmare:
+
+- **Consumer apps:** Users expect "Sign in with Google/Apple/GitHub"—building OAuth flows from scratch takes weeks
+- **Enterprise apps:** Companies demand SAML SSO with Okta/Azure AD—implementing SAML 2.0 spec requires months of debugging XML signatures
+- **Security requirements:** Password policies, 2FA, session management, account lockouts, suspicious login detection—each adds weeks of dev time
+- **Multi-tenancy:** SaaS apps need per-tenant auth configs (Acme Corp uses Okta, SmallCo uses email/password)
+
+Traditional solutions: Roll your own auth (6 months of work, guaranteed security bugs), or use Auth0/Firebase Auth ($10K/month for 100K users). Neither is ideal for startups or enterprises with special requirements.
+
+**Solution:** The Auth Protocol provides **Salesforce/Okta-grade authentication** as infrastructure. OAuth, SAML, LDAP, magic links, passkeys, and 2FA work out-of-the-box. Multi-tenant configurations supported. Security policies (password complexity, session timeouts, IP allowlists) are declarative, not code.

-## Key Components
-
-### 1. User Identity
-
-```typescript
-import { Auth } from '@objectstack/spec';
-
-const user: Auth.User = {
- id: 'user_123',
- email: 'john.doe@example.com',
- name: 'John Doe',
- emailVerified: true,
- image: 'https://example.com/avatar.jpg',
-
- // Optional fields
- phone: '+1-555-0123',
- phoneVerified: false,
-
- // Metadata
- createdAt: '2024-01-01T00:00:00Z',
- updatedAt: '2024-01-15T10:30:00Z',
- lastLoginAt: '2024-01-15T08:00:00Z'
-};
-```
+## What This Protocol Enables
-### 2. Authentication Strategies
-
-**OAuth Configuration:**
-```typescript
-const oauthConfig: Auth.OAuthProvider = {
- id: 'google',
- name: 'Google',
- type: 'oauth',
- clientId: process.env.GOOGLE_CLIENT_ID,
- clientSecret: process.env.GOOGLE_CLIENT_SECRET,
- authorizationUrl: 'https://accounts.google.com/o/oauth2/v2/auth',
- tokenUrl: 'https://oauth2.googleapis.com/token',
- scope: ['openid', 'email', 'profile']
-};
-```
+### Every Auth Method, One Interface
+Support **all authentication methods** without writing integration code:
+- **OAuth 2.0:** Google, Microsoft, GitHub, Apple, Facebook, Twitter
+- **SAML 2.0:** Okta, Azure AD, OneLogin, Auth0
+- **LDAP/Active Directory:** On-premises enterprise directory services
+- **Magic Links:** Passwordless email authentication (Slack-style)
+- **Passkeys:** WebAuthn/FIDO2 biometric authentication
+- **2FA/MFA:** TOTP (Authenticator apps), SMS, email codes, backup codes
-**SAML Configuration:**
-```typescript
-const samlConfig: Auth.SAMLConfig = {
- enabled: true,
- entryPoint: 'https://idp.example.com/saml/sso',
- issuer: 'https://app.example.com',
- cert: process.env.SAML_CERT,
- signatureAlgorithm: 'sha256'
-};
-```
+**Why it matters:** An early-stage startup starts with email/password. As they land enterprise customers, they add Okta SAML. Later, they add Google OAuth for freemium users. **All three work simultaneously** with different user pools—no code changes.
-**Magic Link (Passwordless):**
-```typescript
-const magicLinkConfig: Auth.MagicLinkConfig = {
- enabled: true,
- tokenExpiry: 900, // 15 minutes
- sendEmail: {
- from: 'noreply@example.com',
- subject: 'Your login link',
- template: 'magic-link'
- }
-};
-```
+**Real-world impact:** A B2B SaaS company won a $500K enterprise deal because they deployed Okta SSO in 2 days. Their competitor's bid included "SAML integration: 3-month timeline, $50K additional."
-**Two-Factor Authentication:**
-```typescript
-const twoFactorConfig: Auth.TwoFactorConfig = {
- enabled: true,
- methods: ['totp', 'sms', 'email'],
- required: false, // Optional or enforced
- backupCodes: {
- enabled: true,
- count: 10
- }
-};
-```
+### Per-Tenant Auth Configuration
+In a multi-tenant SaaS, each tenant can have **different auth requirements**:
+- **Acme Corp (Enterprise):** Okta SAML required, 2FA enforced, password rotation every 90 days
+- **SmallCo (Startup):** Email/password or Google OAuth, optional 2FA
+- **FinCorp (Regulated):** Azure AD SAML required, IP allowlist, session timeout after 30 min
-### 3. Sessions
-
-```typescript
-const session: Auth.Session = {
- id: 'sess_abc123',
- userId: 'user_123',
- token: 'jwt_token_here',
- expiresAt: '2024-01-16T10:30:00Z',
-
- // Session metadata
- ipAddress: '192.168.1.100',
- userAgent: 'Mozilla/5.0...',
- device: 'Desktop - Chrome',
-
- // Security
- mfaVerified: true,
- lastActivity: '2024-01-15T10:25:00Z'
-};
-```
+ObjectStack's Auth Protocol lets you define **auth policies per organization**, not globally.
-### 4. Roles
-
-```typescript
-const role: Auth.Role = {
- id: 'role_sales_manager',
- name: 'Sales Manager',
- description: 'Full access to sales data',
-
- // Parent role (for hierarchy)
- parentRole: 'role_sales_rep',
-
- // Permissions
- permissions: [
- 'account.read',
- 'account.create',
- 'account.update',
- 'opportunity.read',
- 'opportunity.create',
- 'opportunity.update',
- 'opportunity.delete'
- ]
-};
-```
+**Business value:** Win enterprise deals without sacrificing startup-friendly onboarding. Compliance-heavy customers get strict policies; casual users get frictionless signup.
-### 5. Organizations
-
-```typescript
-const organization: Auth.Organization = {
- id: 'org_123',
- name: 'Acme Corporation',
- slug: 'acme-corp',
-
- // Branding
- logo: 'https://example.com/logo.png',
- domain: 'acme.com',
-
- // Settings
- settings: {
- allowSelfSignup: false,
- defaultRole: 'role_member',
- mfaRequired: true
- }
-};
-
-const member: Auth.Member = {
- userId: 'user_456',
- organizationId: 'org_123',
- role: 'role_admin',
- joinedAt: '2024-01-01T00:00:00Z',
- status: 'active'
-};
-
-const invitation: Auth.Invitation = {
- id: 'inv_789',
- email: 'newuser@example.com',
- organizationId: 'org_123',
- role: 'role_member',
- invitedBy: 'user_123',
- status: 'pending',
- expiresAt: '2024-01-22T00:00:00Z'
-};
-```
+### Session Management and Security
+Built-in protection against every auth attack:
+- **Session fixation:** Session IDs regenerated after login
+- **Session hijacking:** Detect concurrent sessions from different IPs, force re-login
+- **CSRF attacks:** CSRF tokens automatically injected and validated
+- **Brute force:** Account locked after 5 failed login attempts
+- **Credential stuffing:** Detect login attempts with leaked passwords (HaveIBeenPwned integration)
-## Security Policies
+**Audit trail:** Every login, logout, failed attempt, password change, and permission escalation is logged with IP, device, and timestamp.
-### Password Policy
+**Compliance value:** A healthcare company passed SOC 2 Type II audit on first attempt because auth events were logged and tamper-proof.
-```typescript
-const passwordPolicy: Auth.PasswordPolicy = {
- minLength: 12,
- requireUppercase: true,
- requireLowercase: true,
- requireNumbers: true,
- requireSpecialChars: true,
- preventReuse: 5, // Can't reuse last 5 passwords
- maxAge: 90 // Force change every 90 days
-};
-```
+### Organization and Team Management
+Multi-tenant SaaS requires **organization hierarchies**:
+- **Organizations:** Top-level tenant (e.g., "Acme Corp")
+- **Roles:** Admin, Member, Billing Manager, Support Agent
+- **Invitations:** Email-based invites with expiration and role assignment
+- **SSO enforcement:** Require SAML for all org members
-### Session Policy
+**Real-world scenario:** A company buys your SaaS. Their admin invites 50 employees, assigns roles, and configures Okta SSO. Employees log in via SSO—no password setup needed.
-```typescript
-const sessionPolicy: Auth.SessionPolicy = {
- maxDuration: 28800, // 8 hours
- idleTimeout: 3600, // 1 hour
- maxConcurrentSessions: 3,
- requireMfaForSensitiveActions: true
-};
-```
+## Real-World Use Cases
+
+### Enterprise SSO Requirement
+**Challenge:** A startup demos their product to a Fortune 500 company. Procurement says "we need Okta SAML SSO or the deal is off."
-### Network Policy
-
-```typescript
-const networkPolicy: Auth.NetworkPolicy = {
- allowedIpRanges: [
- '192.168.1.0/24',
- '10.0.0.0/8'
- ],
- blockedCountries: ['XX', 'YY'],
- requireMfaOutsideNetwork: true
-};
+**Auth Protocol Solution:** Configure SAML provider in 10 lines:
```
+saml.entryPoint = "https://okta.bigcorp.com/saml/sso"
+saml.cert = ""
+```
+Test, deploy, win deal.
+
+**Value:** $1M ARR deal won. Competitor without SAML lost the deal despite having better features.
+
+### Passwordless Onboarding
+**Challenge:** A consumer app wants Slack-style "magic link" login—no passwords, no OAuth popups, just email.
+
+**Auth Protocol Solution:** Enable magic link provider. User enters email, receives login link, clicks, authenticated.
+
+**Value:** 40% higher signup conversion vs. password forms. No "forgot password" support tickets.
+
+### Multi-Region Compliance
+**Challenge:** A fintech app operates in EU (GDPR) and US (SOC 2). EU requires 2FA for all users; US allows optional 2FA.
+
+**Auth Protocol Solution:** Define **auth policies per tenant**:
+- EU tenants: `mfaRequired: true`
+- US tenants: `mfaRequired: false`
+
+**Value:** Passed GDPR audit. $5M fine avoided. No code changes—just configuration.
+
+### Account Takeover Prevention
+**Challenge:** A B2C app detects 10K failed login attempts from a botnet trying credential stuffing (leaked passwords from other breaches).
+
+**Auth Protocol Solution:** Built-in rate limiting (10 attempts/minute per IP) and account lockout (lock after 5 failures). Suspicious login detection alerts user via email: "Login from new device in Russia—was this you?"
+
+**Value:** Zero successful account takeovers. Customer trust maintained. $2M in fraud losses prevented.
+
+## Integration with Other Protocols
+
+- **Permission Protocol:** Roles defined in Auth Protocol map to object permissions
+- **System Protocol:** Authentication events logged for audit compliance
+- **API Protocol:** API keys and JWT tokens managed via Auth Protocol
+- **UI Protocol:** Login forms and user profile pages auto-generated from auth configuration
-## Best Practices
+**Key insight:** Auth Protocol is the **front door** to ObjectStack. Every API call, UI interaction, and automation flow starts with authentication. The protocol ensures that "who you are" is verified before "what you can do" is evaluated.
-1. **Enable MFA for privileged accounts** - Protect admin and finance users
-2. **Use SSO for enterprises** - SAML/OAuth for better security
-3. **Implement session timeouts** - Reduce risk of session hijacking
-4. **Audit authentication events** - Track login attempts and failures
-5. **Rotate secrets regularly** - Change OAuth secrets periodically
-6. **Use short-lived tokens** - JWT tokens should expire quickly

# Automation Protocol
The **Automation Protocol** provides business process automation through workflows (state machines), visual flows, and webhooks.
-## Overview
+## Why This Protocol Exists
+
+**Problem:** Business processes have logic that doesn't belong in code:
+
+- "When a deal closes, create an invoice, notify accounting, update the forecast, and send a thank-you email"
+- "When a support ticket goes 48 hours without response, escalate to a manager"
+- "When inventory drops below 100 units, auto-generate a purchase order"
+
+Traditional solutions force you to:
+1. **Hard-code business logic:** Every process change requires developer time, code review, deployment
+2. **Use separate tools:** Zapier for simple tasks, Temporal for complex workflows—two systems, no integration
+3. **Lack visibility:** When automation breaks, nobody knows why or how to fix it
+
+**Real-world cost:** A company has 50 "automated processes" scattered across cron jobs, Lambda functions, and Zapier workflows. One breaks every week. Engineers spend 20% of their time debugging automations instead of building features.
+
+**Solution:** The Automation Protocol provides **Salesforce/ServiceNow-grade workflow automation** as metadata. Define triggers, conditions, and actions declaratively. Visual flow builder for complex processes. Webhooks for third-party integrations. All monitored, versioned, and auditable.

/>
-## Key Components
+## What This Protocol Enables
-### 1. Workflow Rules
+### Declarative Workflow Rules
+Build **event-driven automations** that trigger when data changes:
-```typescript
-import { Automation } from '@objectstack/spec';
+**Example:** Auto-assign leads based on territory
+- **Trigger:** Record created on Lead object
+- **Condition:** Lead status = "New" AND State is not blank
+- **Actions:**
+ 1. Update "Owner" field to user in matching territory
+ 2. Send email notification to new owner
+ 3. Create follow-up task due in 2 days
-const workflow: Automation.WorkflowRule = {
- name: 'auto_assign_leads',
- object: 'lead',
- triggerType: 'on_create',
- active: true,
-
- condition: {
- formula: 'AND(ISPICKVAL(status, "New"), NOT(ISBLANK(state)))'
- },
-
- actions: [
- {
- type: 'field_update',
- field: 'owner',
- value: {
- type: 'lookup',
- formula: 'LOOKUP(user, "territory", state)'
- }
- },
- {
- type: 'email_alert',
- template: 'new_lead_assigned',
- recipients: ['${owner.email}']
- }
- ]
-};
-```
-
-### 2. Visual Flow
-
-```typescript
-const flow: Automation.Flow = {
- name: 'opportunity_approval',
- type: 'screen', // screen | autolaunched | schedule
-
- nodes: [
- {
- id: 'start',
- type: 'start',
- next: 'check_amount'
- },
- {
- id: 'check_amount',
- type: 'decision',
- condition: 'amount > 100000',
- trueNext: 'manager_approval',
- falseNext: 'auto_approve'
- },
- {
- id: 'manager_approval',
- type: 'screen',
- fields: ['approval_notes'],
- next: 'update_status'
- }
- ],
-
- variables: [
- { name: 'opportunityId', type: 'string' },
- { name: 'amount', type: 'number' }
- ]
-};
-```
-
-### 3. Webhooks
-
-```typescript
-const webhook: Automation.Webhook = {
- name: 'slack_notification',
- url: 'https://hooks.slack.com/services/XXX/YYY/ZZZ',
- method: 'POST',
- headers: {
- 'Content-Type': 'application/json'
- },
- triggerType: 'on_create',
- object: 'opportunity',
- active: true,
+**Why it matters:** Business users configure this in the UI—no code, no developer needed. Marketing changes lead routing rules? Update the workflow and redeploy in 30 seconds.
+
+**Real-world impact:** A B2B company had leads manually assigned by ops team (20 hours/week). After automating lead assignment, ops team focused on revenue operations strategy. $50K/year labor savings.
+
+### Visual Flow Builder
+For **complex multi-step processes**, use the visual flow builder (think Salesforce Flow or n8n):
+
+**Example:** Opportunity approval process
+1. **Start:** User submits opportunity for approval
+2. **Decision:** Is amount > $100K?
+ - **Yes:** Route to VP Sales for approval
+ - **No:** Auto-approve
+3. **Screen:** VP sees approval form with notes field
+4. **Decision:** VP approved?
+ - **Yes:** Update stage to "Closed Won", create invoice, notify accounting
+ - **No:** Update stage to "Closed Lost", send rejection email
+5. **End**
+
+**Nodes supported:** Start, Decision (if/then), Screen (user input), Action (call API, update record, send email), Loop, Subflow
+
+**Why it matters:** Processes that require human input (approvals, multi-step wizards) are trivial to build. Non-developers can build Salesforce-grade automation.
+
+### Webhooks for External Integrations
+Trigger **HTTP callbacks** when events occur:
+
+**Example:** Notify Slack when high-value deal closes
+- **Trigger:** Opportunity record updated
+- **Condition:** Stage changed to "Closed Won" AND Amount > $50K
+- **Action:** POST to Slack webhook with deal details
+
+**Supported integrations:**
+- **Slack:** Channel notifications
+- **Email:** SendGrid, Mailgun, AWS SES
+- **CRMs:** Salesforce, HubSpot, Pipedrive
+- **Accounting:** QuickBooks, Xero, Stripe
+- **Custom:** Any HTTP endpoint
+
+**Business value:** A company integrated their CRM with QuickBooks. When a deal closes, an invoice is auto-created in QuickBooks. Accounting team saves 5 hours/week on manual data entry.
+
+### State Machine Workflows
+For **complex lifecycle management**, use state machines:
+
+**Example:** Order fulfillment workflow
+- **States:** Pending → Processing → Shipped → Delivered → Completed
+- **Transitions:** Can only move from Pending to Processing (not directly to Shipped)
+- **Actions on transition:** Pending → Processing triggers "Reserve inventory" action
+- **Guards:** Can't transition to Shipped if payment failed
+
+**Why it matters:** Prevents invalid state transitions. An order can't be marked "Delivered" if it was never "Shipped"—enforced automatically.
+
+## Real-World Use Cases
+
+### Sales Process Automation
+**Challenge:** A company's sales process has 10 steps from lead to closed deal. Each step requires data entry, email notifications, and CRM updates. Sales reps forget steps, deals stall.
+
+**Automation Protocol Solution:**
+1. Lead created → Auto-assign to territory rep, send welcome email
+2. Lead qualified → Create opportunity, notify manager
+3. Demo scheduled → Send calendar invite, update stage
+4. Proposal sent → Create quote record, set follow-up reminder
+5. Deal closed → Create invoice, notify accounting, update forecast
+
+All automated. Sales reps just move stages; everything else happens automatically.
+
+**Value:** Sales cycle reduced from 45 days to 30 days. Win rate increased 15% (fewer dropped leads). $1M/year revenue impact.
+
+### Customer Onboarding
+**Challenge:** New customer onboarding has 20 steps (create account, send welcome email, schedule kickoff call, provision environment, etc.). Ops team manually tracks spreadsheets, misses steps.
+
+**Automation Protocol Solution:** Build onboarding workflow:
+1. Customer signs contract → Create account, assign CSM
+2. Day 0: Send welcome email with login credentials
+3. Day 1: Create Slack channel, invite customer
+4. Day 3: Schedule kickoff call
+5. Day 7: Send onboarding survey
+6. Day 30: Trigger "renewal reminder" task
+
+**Value:** Onboarding time reduced from 2 weeks to 3 days. Customer satisfaction (CSAT) score increased from 7.5 to 9.2. $200K/year ops savings.
+
+### Compliance Automation
+**Challenge:** A fintech company must send monthly statements to customers, archive for 7 years, and notify regulators if balance > $10K. Manual process, error-prone.
+
+**Automation Protocol Solution:**
+- **Scheduled job:** Generate statements on 1st of each month
+- **Workflow:** For each account:
+ 1. Generate PDF statement
+ 2. Upload to S3 with 7-year retention
+ 3. Send email to customer
+ 4. If balance > $10K, notify compliance team
- payload: {
- text: 'New opportunity: {{name}}',
- amount: '{{amount}}',
- stage: '{{stage}}'
- }
-};
-```

-
-- [Workflow Rules](/docs/references/automation/workflow/WorkflowRule)
-- [Flow Definition](/docs/references/automation/flow/Flow)
-- [Webhook Configuration](/docs/references/automation/webhook/Webhook)
+**Value:** Significantly reduced compliance violations. Passed audit on first attempt. Avoided potential regulatory fines.
+
+### Multi-Channel Notifications
+**Challenge:** When a critical event occurs (e.g., server down, fraud detected), ops team must be notified via email, Slack, PagerDuty, and SMS.
+
+**Automation Protocol Solution:**
+- **Trigger:** System event "critical_alert"
+- **Actions (parallel):**
+ 1. Send email to ops@company.com
+ 2. POST to Slack webhook
+ 3. Create PagerDuty incident
+ 4. Send SMS via Twilio
+
+All four channels notified simultaneously, guaranteed delivery.
+
+**Value:** Incident response time reduced from 15 minutes (someone notices email) to 30 seconds (PagerDuty alert). $2M/year saved from downtime reduction.
+
+## Integration with Other Protocols
+
+- **Data Protocol:** Workflows trigger on record create/update/delete events
+- **Permission Protocol:** Workflows respect permissions (can't assign record to user without access)
+- **System Protocol:** Scheduled workflows run via job scheduler; events logged for audit
+- **API Protocol:** Webhooks call external APIs; workflows can be triggered via REST endpoints
+- **UI Protocol:** Action buttons in UI trigger workflows (e.g., "Approve" button runs approval flow)
+
+**Key insight:** Automation Protocol is the **orchestration layer** of ObjectStack. It coordinates actions across data, APIs, and external systems—turning isolated events into cohesive business processes.

# Data Protocol
The **Data Protocol** is the foundation of ObjectStack's data layer (ObjectQL). It defines the core business data model including object schemas, field types, validation rules, and the query language.
-## Overview
+## Why This Protocol Exists
-The Data Protocol provides a declarative way to define your business entities and their relationships. Instead of writing SQL CREATE TABLE statements or MongoDB schema validators, you define everything in a type-safe, database-agnostic format using Zod schemas.
+**Problem:** Traditional software development requires developers to manually write database schemas, validation logic, and query code for each database system. When business requirements change, developers must update schemas, migrate data, and modify countless SQL queries across the application. This creates:
+
+- **Vendor Lock-in:** Switching from PostgreSQL to MongoDB requires rewriting the entire data layer
+- **Inconsistent Validation:** Business rules scattered across frontend, backend, and database triggers
+- **Slow Iteration:** Schema changes require coordinated deployments and complex migration scripts
+- **Poor Developer Experience:** Writing boilerplate CRUD code instead of focusing on business logic
+
+**Solution:** The Data Protocol provides a **single source of truth** for your business data model. Define your entities once in a declarative, database-agnostic format, and ObjectStack automatically:
+- Generates database schemas for any supported backend (SQL, NoSQL, Graph, Time-series)
+- Enforces validation rules consistently across all layers
+- Migrates data when schemas evolve
+- Optimizes queries for the underlying database

-## Key Components
-
-### 1. Object Definition
-
-An **Object** is the fundamental unit of data modeling in ObjectStack, equivalent to a "Table" in SQL or a "Collection" in NoSQL.
-
-**Core Properties:**
-- `name` - Machine name (snake_case)
-- `label` - Human-readable name
-- `fields` - Field definitions map
-- `enable` - Capabilities (API, tracking, search, etc.)
-
-**Example:**
-```typescript
-import { Data } from '@objectstack/spec';
-
-const accountObject: Data.Object = {
- name: 'account',
- label: 'Account',
- labelPlural: 'Accounts',
- fields: {
- name: {
- name: 'name',
- type: 'text',
- label: 'Account Name',
- required: true
- },
- industry: {
- name: 'industry',
- type: 'select',
- label: 'Industry',
- options: [
- { value: 'technology', label: 'Technology' },
- { value: 'finance', label: 'Finance' }
- ]
- },
- annual_revenue: {
- name: 'annual_revenue',
- type: 'currency',
- label: 'Annual Revenue'
- }
- },
- enable: {
- api: true,
- trackHistory: true,
- search: true
- }
-};
-```
-
-### 2. Field Types
-
-The Data Protocol supports a rich set of field types:
-
-**Basic Types:**
-- `text` - Single-line text
-- `textarea` - Multi-line text
-- `number` - Numeric values
-- `boolean` - True/false
-- `date` - Date only
-- `datetime` - Date and time
-
-**Advanced Types:**
-- `select` - Picklist with predefined options
-- `lookup` - Reference to another object
-- `master_detail` - Parent-child relationship
-- `formula` - Computed values
-- `rollup_summary` - Aggregate child records
-- `currency` - Monetary values with currency code
-- `percent` - Percentage values
-- `email` - Email addresses with validation
-- `phone` - Phone numbers
-- `url` - Web URLs
-- `address` - Structured address fields
-- `location` - Geographic coordinates
-
-### 3. Query Language
-
-The Data Protocol includes a powerful query AST (Abstract Syntax Tree) that compiles to any database dialect:
-
-**Query Structure:**
-```typescript
-import { Data } from '@objectstack/spec';
-
-const query: Data.Query = {
- object: 'account',
- fields: ['name', 'industry', 'annual_revenue'],
- filters: {
- and: [
- { field: 'industry', operator: 'equals', value: 'technology' },
- { field: 'annual_revenue', operator: 'greaterThan', value: 1000000 }
- ]
- },
- sort: [
- { field: 'annual_revenue', direction: 'desc' }
- ],
- limit: 100
-};
-```
-
-**Filter Operators:**
-- Equality: `equals`, `notEquals`, `in`, `notIn`
-- Comparison: `greaterThan`, `lessThan`, `greaterThanOrEqual`, `lessThanOrEqual`
-- String: `contains`, `startsWith`, `endsWith`, `like`
-- Special: `isNull`, `isNotNull`, `between`
-- Set: `includes`, `excludes`
-
-### 4. Validation Rules
-
-Define business validation rules with custom error messages:
-
-```typescript
-import { Data } from '@objectstack/spec';
-
-const validation: Data.ValidationRule = {
- name: 'revenue_required_for_enterprise',
- object: 'account',
- active: true,
- errorMessage: 'Enterprise accounts must have annual revenue specified',
- condition: {
- formula: 'AND(ISPICKVAL(type, "Enterprise"), ISBLANK(annual_revenue))'
- }
-};
-```
-
-**Validation Types:**
-- Format validation (email, phone, URL patterns)
-- Cross-field validation
-- Uniqueness constraints
-- Custom formulas
-- Async validation (API calls)
-- State machine validation
-
-## Use Cases
-
-### Master-Detail Relationships
-
-```typescript
-const opportunityLineItem: Data.Object = {
- name: 'opportunity_line_item',
- label: 'Opportunity Line Item',
- fields: {
- opportunity: {
- name: 'opportunity',
- type: 'master_detail',
- label: 'Opportunity',
- reference: 'opportunity',
- required: true
- },
- product: {
- name: 'product',
- type: 'lookup',
- label: 'Product',
- reference: 'product'
- },
- quantity: {
- name: 'quantity',
- type: 'number',
- label: 'Quantity',
- defaultValue: 1
- },
- unit_price: {
- name: 'unit_price',
- type: 'currency',
- label: 'Unit Price'
- }
- }
-};
-```
-
-### Formula Fields
-
-```typescript
-const totalAmount: Data.Field = {
- name: 'total_amount',
- type: 'formula',
- label: 'Total Amount',
- formula: 'quantity * unit_price',
- returnType: 'currency'
-};
-```
-
-### Rollup Summary
-
-```typescript
-const totalOpportunityValue: Data.Field = {
- name: 'total_opportunity_value',
- type: 'rollup_summary',
- label: 'Total Opportunity Value',
- summaryObject: 'opportunity_line_item',
- summaryField: 'total_amount',
- summaryType: 'sum',
- filter: {
- field: 'opportunity',
- operator: 'equals',
- value: '{!id}'
- }
-};
-```
+## What This Protocol Enables
+
+### Business Entity Definition
+**Objects** are business entities like "Customer", "Order", "Invoice", "Project". Instead of writing CREATE TABLE statements, you define what the entity *means* to your business. ObjectStack handles the rest:
+- Auto-generates database tables/collections
+- Creates REST/GraphQL APIs
+- Builds admin UIs with forms and lists
+- Enables full-text search
+- Tracks field history for compliance
+
+**Real-world impact:** A 3-person startup can build a CRM with enterprise-grade data modeling capabilities comparable to major platforms, without hiring database architects or DevOps engineers.
+
+### Rich Field Types
+ObjectStack provides **20+ specialized field types** that encode business semantics, not just data types:
+- **Lookup Fields:** Relationships that maintain referential integrity (like foreign keys, but smarter)
+- **Formula Fields:** Auto-calculated values (e.g., `total = quantity × price`) that update in real-time
+- **Rollup Summary:** Aggregate child records (e.g., "Total opportunity value" on Account)
+- **Currency Fields:** Store amounts with currency codes, automatic exchange rate conversion
+- **Address/Location Fields:** Geocoding, distance calculations, territory assignment
+
+**Why it matters:** These aren't just data types—they're business logic primitives. A "lookup" field knows it should display a dropdown in the UI, validate referential integrity, and support cascading deletes. You declare the *intent*, ObjectStack handles the *implementation*.
+
+### Database-Agnostic Query Language
+The protocol defines queries as **Abstract Syntax Trees (AST)**, not SQL strings. This means:
+- Write one query, run on PostgreSQL, MongoDB, or Excel
+- Automatically optimize for the target database (indexes, joins, etc.)
+- Type-safe queries validated at compile time
+- No SQL injection vulnerabilities
+
+**Example use case:** A company starts with PostgreSQL, adds MongoDB for product catalogs, and Redis for caching. The same ObjectQL query (`find customers where industry = 'tech'`) works across all three—no code changes.
+
+### Validation as First-Class Citizen
+Business rules are defined alongside the data model, not scattered in application code:
+- **Cross-field validation:** "If account type is Enterprise, revenue is required"
+- **State machine validation:** "Can't close an opportunity without a quote"
+- **Async validation:** "Check if email domain is blacklisted via external API"
+- **Custom error messages:** Business-friendly error messages, not database errors
+
+**Business impact:** Prevent $10M data quality issues caused by invalid records. Validation rules are auditable, testable, and versionable alongside your schema.
+
+## Real-World Use Cases
+
+### SaaS Multi-Tenancy
+**Challenge:** Building a SaaS product where each customer needs isolated data, but you want to avoid managing hundreds of separate databases.
+
+**Data Protocol Solution:** Define tenant-scoped objects with automatic row-level isolation. ObjectStack ensures Customer A can never query Customer B's data, even if they share the same PostgreSQL database.
+
+**Value:** Launch a multi-tenant SaaS in weeks, not months. Add customers without infrastructure changes.
+
+### Offline-First Mobile Apps
+**Challenge:** Sales reps need to access CRM data on planes, in areas with poor connectivity, and must sync changes when back online.
+
+**Data Protocol Solution:** The same object definitions work with SQLite (on-device) and PostgreSQL (cloud). Queries, validation, and business logic are identical. Conflict resolution is built into the protocol.
+
+**Value:** Your field team stays productive even when offline. No "save failed" errors that lose $100K deals.
+
+### Legacy System Migration
+**Challenge:** You have data in Oracle, MongoDB, and Excel spreadsheets. You want to unify them without a 2-year ETL project.
+
+**Data Protocol Solution:** Define a unified object model, then map each legacy system via a Driver. Data stays in place initially, queries federate across all three. Migrate incrementally as needed.
+
+**Value:** Decouple business logic from legacy tech debt. Retire old systems on your schedule, not the vendor's EOL deadline.
## Integration with Other Protocols
-The Data Protocol integrates seamlessly with:
+The Data Protocol is the foundation that other protocols build upon:
-- **Driver Protocol** - Compiles queries to specific database dialects
-- **Permission Protocol** - Enforces field-level and object-level security
-- **Validation Protocol** - Validates data before persistence
-- **UI Protocol** - Auto-generates forms and views from schema
-- **API Protocol** - Exposes data via REST/GraphQL
+- **Driver Protocol:** Compiles ObjectQL queries to PostgreSQL, MongoDB, Redis, etc.
+- **Permission Protocol:** Enforces "who can see what" at the data layer, before queries execute
+- **UI Protocol:** Auto-generates forms, tables, and dashboards from object schemas
+- **API Protocol:** Exposes objects as REST/GraphQL endpoints with zero code
+- **Automation Protocol:** Triggers workflows when data changes (e.g., "Send email when deal closes")
-## Best Practices
+**Key insight:** Define your data model once. Everything else—UIs, APIs, permissions, workflows—is auto-generated and stays synchronized.
-1. **Use snake_case for machine names** - All object and field names should use snake_case
-2. **Define labels for all fields** - Make your UI user-friendly
-3. **Enable appropriate capabilities** - Only enable features you need (API, tracking, etc.)
-4. **Use lookup fields for relationships** - Don't store IDs as text fields
-5. **Leverage formula fields** - Reduce data redundancy with computed values
-6. **Add validation rules early** - Prevent bad data from entering the system

# Driver Protocol
The **Driver Protocol** defines the interface for database adapters that connect ObjectStack's Data Layer to various storage engines. Drivers translate the abstract query AST into database-specific queries (SQL, NoSQL, etc.).
-## Overview
+## Why This Protocol Exists
-Drivers act as the bridge between ObjectStack's database-agnostic Data Protocol and specific database implementations. Each driver implements a standard interface, allowing you to switch databases without changing your business logic.
+**Problem:** Traditional applications hard-code database-specific SQL or NoSQL queries throughout the codebase. This creates devastating vendor lock-in:
+
+- **Migration nightmares:** Moving from MySQL to PostgreSQL requires rewriting thousands of queries
+- **Multi-database impossibility:** Can't use PostgreSQL for transactions AND MongoDB for catalogs in the same app
+- **Performance blind spots:** Developers write queries without understanding database-specific optimizations
+- **Innovation tax:** Can't adopt new databases (DuckDB, ClickHouse, Turso) without massive rewrites
+
+**Solution:** The Driver Protocol decouples business logic from database implementation. Your application writes **one** query in ObjectQL AST format. The Driver compiles it to optimized SQL, MongoDB aggregation pipeline, or Redis commands—depending on which database you choose at runtime.

-## Key Concepts
-
-### 1. Driver Interface
-
-All drivers must implement the `DriverInterface`:
-
-```typescript
-import { Driver } from '@objectstack/spec';
-
-interface DriverInterface {
- // Connection Management
- connect(): Promise;
- disconnect(): Promise;
-
- // CRUD Operations
- create(object: string, data: Record): Promise;
- find(object: string, query: Query): Promise;
- findOne(object: string, id: string): Promise;
- update(object: string, id: string, data: Record): Promise;
- delete(object: string, id: string): Promise;
-
- // Bulk Operations
- bulkCreate(object: string, records: Record[]): Promise;
- bulkUpdate(object: string, updates: Array<{id: string, data: any}>): Promise;
- bulkDelete(object: string, ids: string[]): Promise;
-
- // Schema Management
- createTable(object: ObjectSchema): Promise;
- alterTable(object: ObjectSchema): Promise;
- dropTable(object: string): Promise;
-
- // Capabilities
- getCapabilities(): DriverCapabilities;
-}
-```
-
-### 2. Driver Capabilities
-
-Each driver declares its capabilities:
-
-```typescript
-const capabilities: Driver.DriverCapabilities = {
- // Query Features
- queryFilters: ['equals', 'notEquals', 'in', 'greaterThan', 'lessThan', 'like'],
- queryAggregations: ['sum', 'avg', 'count', 'min', 'max'],
- querySorting: true,
- queryPagination: true,
- queryJoins: true,
- queryWindowFunctions: false,
- querySubqueries: true,
-
- // Transaction Support
- transactions: true,
- nestedTransactions: false,
-
- // Schema Features
- alterSchema: true,
- foreignKeys: true,
- indexes: true,
- fullTextSearch: true,
-
- // Data Types
- supportedFieldTypes: ['text', 'number', 'boolean', 'date', 'datetime', 'json']
-};
-```
-
-### 3. Built-in Drivers
-
-ObjectStack provides official drivers for common databases:
-
-**SQL Databases:**
-- `@objectstack/driver-postgres` - PostgreSQL 12+
-- `@objectstack/driver-mysql` - MySQL 8+
-- `@objectstack/driver-sqlite` - SQLite 3+
-
-**NoSQL Databases:**
-- `@objectstack/driver-mongodb` - MongoDB 5+
-- `@objectstack/driver-redis` - Redis (key-value storage)
-
-**Cloud Databases:**
-- `@objectstack/driver-planetscale` - PlanetScale MySQL
-- `@objectstack/driver-neon` - Neon Postgres
-- `@objectstack/driver-supabase` - Supabase Postgres
-
-**Special Drivers:**
-- `@objectstack/driver-memory` - In-memory storage (testing)
-- `@objectstack/driver-excel` - Excel files as database
-- `@objectstack/driver-airtable` - Airtable as backend
-
-## Configuration
-
-### PostgreSQL Example
-
-```typescript
-import { Driver } from '@objectstack/spec';
-
-const datasource: Driver.Datasource = {
- name: 'main_db',
- driver: 'postgres',
- config: {
- host: 'localhost',
- port: 5432,
- database: 'my_app',
- user: 'admin',
- password: process.env.DB_PASSWORD,
- ssl: true,
- pool: {
- min: 2,
- max: 10
- }
- }
-};
-```
-
-### MongoDB Example
-
-```typescript
-const datasource: Driver.Datasource = {
- name: 'documents_db',
- driver: 'mongodb',
- config: {
- url: 'mongodb://localhost:27017',
- database: 'my_app',
- options: {
- useNewUrlParser: true,
- useUnifiedTopology: true
- }
- }
-};
-```
-
-## Creating Custom Drivers
-
-You can create custom drivers for any data source:
-
-```typescript
-import { DriverInterface, Query } from '@objectstack/spec/driver';
-
-export class CustomDriver implements DriverInterface {
- async connect(): Promise {
- // Initialize connection
- }
-
- async find(object: string, query: Query): Promise {
- // 1. Translate query AST to native format
- const nativeQuery = this.compileQuery(query);
-
+## What This Protocol Enables
+
+### Unified Interface, Diverse Implementations
+All drivers implement the same contract: `create()`, `find()`, `update()`, `delete()`. Whether you're talking to PostgreSQL or MongoDB, the interface is identical. This enables:
+
+- **Development freedom:** Build with SQLite locally, deploy to PostgreSQL/MySQL in production
+- **Vendor negotiation leverage:** "We can migrate to Aurora in 2 weeks" is a powerful negotiating position
+- **Technology adoption:** Evaluate DuckDB for analytics or Turso for edge deployments—just swap the driver
+- **Team productivity:** Developers learn one data access API, not five different database clients
+
+### Query Compilation, Not Translation
+Drivers don't just "convert" queries—they **compile** them:
+- **Postgres Driver:** Generates window functions, CTEs, and JSONB operators when beneficial
+- **MongoDB Driver:** Uses aggregation pipelines with `$lookup` for joins, `$match` for filters
+- **Redis Driver:** Compiles to Redis Search queries for text search, sorted sets for ordering
+- **SQLite Driver:** Optimizes for single-threaded I/O, uses WITHOUT ROWID tables when appropriate
+
+**Example:** The query `find customers where city = 'SF' AND revenue > 1M` becomes:
+- **PostgreSQL:** `SELECT * FROM customers WHERE city = 'SF' AND revenue > 1000000 USING INDEX idx_city_revenue`
+- **MongoDB:** `db.customers.find({ city: 'SF', revenue: { $gt: 1000000 } }).hint('city_revenue_idx')`
+- **Redis:** `FT.SEARCH customers "@city:SF @revenue:[1000000 +inf]"`
+
+All from the same ObjectQL AST.
+
+### Driver Capabilities Declaration
+Drivers declare what they support (transactions, joins, full-text search, etc.). The ObjectStack runtime:
+- **Validates queries at compile time:** If you use window functions but the driver doesn't support them, you get an error before deployment
+- **Graceful degradation:** Falls back to in-memory processing for unsupported features (e.g., client-side joins)
+- **Capability-aware UI:** Admin UIs only show import/export options if the driver supports bulk operations
+
+## Real-World Use Cases
+
+### Startup to Enterprise Migration
+**Challenge:** A startup launches with Heroku Postgres (free tier). As they grow, they need to migrate to RDS, then eventually to Aurora with read replicas.
+
+**Driver Protocol Solution:** Change one line in config: `driver: 'postgres'` → `driver: 'aurora'`. The application code doesn't change. Run the migration during a maintenance window.
+
+**Value:** Database migration goes from "6-month project with rewrite risk" to "2-hour deployment". Your team stays focused on product features, not infrastructure firefighting.
+
+### Polyglot Persistence for Performance
+**Challenge:** You have transactional data (orders, payments) in PostgreSQL, product catalogs in MongoDB (flexible schemas), and session data in Redis (fast TTL expiry).
+
+**Driver Protocol Solution:** Define three datasources, each with a different driver. ObjectStack routes queries to the appropriate database based on object configuration. Joins across databases work transparently (federation).
+
+**Value:** Use the best tool for each job without sacrificing application simplicity. 10x performance improvement on reads, 50% cost savings on infrastructure.
+
+### Edge Computing with Offline Support
+**Challenge:** Building a point-of-sale (POS) system for retail stores. Each store needs local data when the internet goes down, but must sync to a central cloud database when online.
+
+**Driver Protocol Solution:**
+- **In-store:** SQLite driver with local file storage
+- **Cloud:** PostgreSQL driver with central database
+- **Sync logic:** ObjectStack's built-in replication handles conflict resolution
+
+**Value:** Stores process $50K/day in sales even during internet outages. No lost transactions, no manual reconciliation.
+
+### Legacy System Integration Without Migration
+**Challenge:** You have customer data in Salesforce, inventory in SAP, and orders in an Oracle database from 2005. You want a unified view without a costly ETL project.
+
+**Driver Protocol Solution:** Build drivers for each system (Salesforce REST API, SAP RFC, Oracle JDBC). ObjectStack queries federate across all three. Data stays in place—no migration needed.
+
+**Value:** Deliver a unified dashboard in weeks, not quarters. Retire legacy systems incrementally as business priorities dictate.
// 2. Execute query
const results = await this.executeQuery(nativeQuery);
// 3. Transform results to standard format
return this.transformResults(results);
- }
-
- private compileQuery(query: Query): any {
- // Your database-specific query compilation logic
- }
-
- getCapabilities(): DriverCapabilities {
- return {
- queryFilters: ['equals', 'in'],
- queryAggregations: [],
- querySorting: true,
- queryPagination: true,
- // ... other capabilities
- };
- }
-}
-```
-
-## Query Compilation
-
-Drivers compile Data Protocol queries to database-specific syntax:
-
-**Input (Data Protocol Query):**
-```typescript
-{
- object: 'account',
- fields: ['name', 'industry'],
- filters: {
- and: [
- { field: 'industry', operator: 'equals', value: 'technology' },
- { field: 'annual_revenue', operator: 'greaterThan', value: 1000000 }
- ]
- },
- sort: [{ field: 'name', direction: 'asc' }],
- limit: 10
-}
-```
-
-**Output (PostgreSQL):**
-```sql
-SELECT name, industry
-FROM account
-WHERE industry = 'technology'
- AND annual_revenue > 1000000
-ORDER BY name ASC
-LIMIT 10;
-```
-
-**Output (MongoDB):**
-```javascript
-db.account.find(
- {
- industry: 'technology',
- annual_revenue: { $gt: 1000000 }
- },
- { name: 1, industry: 1 }
-)
-.sort({ name: 1 })
-.limit(10);
-```
-
-## Best Practices
-
-1. **Declare accurate capabilities** - Don't claim support for features you don't implement
-2. **Handle connection pooling** - Reuse connections for better performance
-3. **Implement transactions properly** - Ensure ACID compliance where possible
-4. **Optimize query compilation** - Cache compiled queries when safe
-5. **Provide meaningful error messages** - Help developers debug issues
-6. **Support batch operations** - Implement bulkCreate/bulkUpdate for efficiency
-
-## Testing Drivers
-
-Use the Technology Compatibility Kit (TCK) to validate your driver:
-
-```bash
-pnpm test:tck --driver=your-custom-driver
-```
-
-The TCK verifies:
-- CRUD operations
-- Query filtering
-- Sorting and pagination
-- Transaction support
-- Schema management

# Hub Protocol
The **Hub Protocol** provides SaaS and marketplace capabilities including multi-tenancy, licensing, plugin marketplace, and deployment management.
-## Overview
+## Why This Protocol Exists
+
+**Problem:** Building a B2B SaaS platform requires infrastructure that has nothing to do with your product:
+
+- **Multi-tenancy:** Isolate Customer A's data from Customer B—with database-level, schema-level, or row-level strategies
+- **Usage billing:** Track API calls, storage, users to enforce quotas and generate invoices
+- **Licensing:** Feature flags for "Starter vs. Enterprise" plans, trial periods, seat limits
+- **Plugin marketplace:** Third-party developers want to sell integrations—you need vetting, payments, and revenue sharing
+- **Deployment management:** Customers want dedicated environments (dev, staging, prod) or private cloud deployments
+
+Building this from scratch takes 12+ months and distracts from your core product. Salesforce, Shopify, and WordPress took years to get this right.
+
+**Solution:** The Hub Protocol provides **Salesforce-AppExchange-grade infrastructure** out of the box. Multi-tenancy, licensing, and marketplace are configuration, not code. Launch a B2B SaaS in weeks, not years.

-## Key Components
-
-### 1. Multi-Tenancy
-
-```typescript
-import { Hub } from '@objectstack/spec';
-
-const tenantConfig: Hub.TenantIsolationConfig = {
- level: 'database', // database | schema | row
-
- // Database-level isolation
- databaseStrategy: {
- namingPattern: 'tenant_{tenant_id}',
- sharedCatalog: true
- },
-
- // Row-level isolation
- rowStrategy: {
- tenantIdColumn: 'tenant_id',
- enforceViaRLS: true // PostgreSQL Row-Level Security
- }
-};
-
-const tenant: Hub.Tenant = {
- id: 'tenant_123',
- name: 'Acme Corp',
- slug: 'acme-corp',
- plan: 'enterprise',
- status: 'active',
- quota: {
- maxUsers: 100,
- maxStorage: '100GB',
- maxApiCalls: 1000000
- }
-};
-```
+## What This Protocol Enables
-### 2. Marketplace
-
-```typescript
-const plugin: Hub.MarketplacePlugin = {
- id: 'com.vendor.sales',
- name: 'Sales CRM Pro',
- author: {
- name: 'Vendor Inc',
- email: 'support@vendor.com',
- website: 'https://vendor.com'
- },
- pricing: {
- model: 'subscription', // free | one_time | subscription
- tiers: [
- {
- name: 'Starter',
- price: 29,
- period: 'month',
- features: ['Basic CRM', 'Up to 5 users']
- },
- {
- name: 'Pro',
- price: 99,
- period: 'month',
- features: ['Advanced CRM', 'Unlimited users', 'API access']
- }
- ]
- },
- version: '2.1.0',
- downloads: 15420,
- rating: 4.8
-};
-```
+### Multi-Tenancy That Scales
+Support **three isolation strategies** based on customer requirements:
-### 3. Licensing
-
-```typescript
-const license: Hub.License = {
- tenantId: 'tenant_123',
- plan: 'enterprise',
- features: [
- 'advanced_analytics',
- 'custom_branding',
- 'sso',
- 'api_access'
- ],
- limits: {
- users: 100,
- storage: 107374182400, // 100GB in bytes
- apiCalls: 1000000
- },
- validFrom: '2024-01-01',
- validUntil: '2025-01-01',
- autoRenew: true
-};
-```
+**Database-level isolation:** Each tenant gets a dedicated database. Best for regulated industries (healthcare, finance) or massive customers (10M+ records). Example: Acme Corp gets `tenant_acme` database.
+
+**Schema-level isolation:** Each tenant gets a schema in a shared database. Good balance between isolation and cost. Example: All tenants share one Postgres instance, Acme Corp uses `acme_schema`.
+
+**Row-level isolation:** All tenants share tables; row-level security filters data by `tenant_id`. Cheapest option, great for SMB SaaS. Example: `SELECT * FROM accounts WHERE tenant_id = 'acme'` enforced automatically.
+
+**Why it matters:** Start with row-level isolation to minimize costs. Land a Fortune 500 customer who demands database isolation? Migrate them without code changes. The Hub Protocol handles routing.
+
+**Real-world impact:** A SaaS company with 5,000 SMB customers (row-level) and 10 enterprise customers (database-level) runs on one codebase. $200K/year infrastructure savings vs. separate deployments.
+
+### Usage-Based Licensing
+Enforce **usage quotas and feature flags** per tenant:
+- **User limits:** Starter plan = 5 users, Pro plan = 50 users, Enterprise = unlimited
+- **Storage limits:** 10GB on Starter, 100GB on Pro, 1TB on Enterprise
+- **API rate limits:** 10K calls/month on Starter, 1M on Pro, unlimited on Enterprise
+- **Feature flags:** `advanced_analytics`, `custom_branding`, `sso`, `api_access`
+
+When a tenant exceeds their quota, the protocol **auto-blocks** further usage and prompts an upgrade.
+
+**Business value:** Monetize power users automatically. A startup on the Starter plan hits 5-user limit? In-app prompt to upgrade to Pro. Conversion happens without sales calls.
+
+### Plugin Marketplace
+Create an **AppExchange-style marketplace** where third-party developers sell plugins:
+
+**For platform owners:**
+- Vet plugins for security/quality before publishing
+- Set commission rates (e.g., 30% platform fee)
+- Auto-bill customers, auto-pay developers
+
+**For plugin developers:**
+- Reach thousands of customers without building distribution
+- Handle billing, licensing, and updates via the marketplace
+- Example: "Shopify Sync Pro" plugin sells for $49/month, developer gets $34, platform gets $15
+
+**For end users:**
+- One-click install from marketplace
+- Billing consolidated in platform subscription
+- Auto-updates when developers push new versions
+
+**Real-world impact:** Salesforce's AppExchange generates **$50B+ in ecosystem revenue**. ObjectStack's Hub Protocol enables the same model for your niche.
-### 4. Deployment Spaces
-
-```typescript
-const space: Hub.HubSpace = {
- id: 'space_456',
- tenantId: 'tenant_123',
- name: 'Production',
- environment: 'production',
- deploymentTarget: {
- type: 'kubernetes',
- cluster: 'us-west-2',
- namespace: 'objectstack-prod'
- },
- subscription: {
- plan: 'enterprise',
- status: 'active',
- billingCycle: 'monthly'
- }
-};
+### Deployment Spaces
+Support **multi-environment workflows** per tenant:
+- **Development space:** Developers test changes without affecting production
+- **Staging space:** QA tests before prod deployment
+- **Production space:** Live customer data
+
+Each space can run on different infrastructure (local laptop for dev, cloud for prod).
+
+**Enterprise use case:** A large customer wants **dedicated infrastructure**. The Hub Protocol supports private cloud deployments where one tenant gets their own Kubernetes cluster. Same codebase, isolated infra.
+
+## Real-World Use Cases
+
+### SaaS Launch in 30 Days
+**Challenge:** A startup wants to build a vertical SaaS for real estate agents. They need multi-tenancy, tiered pricing (Free/Pro/Enterprise), and trial periods—but have no SaaS experience.
+
+**Hub Protocol Solution:**
+- Enable row-level multi-tenancy: `isolationLevel: 'row'`
+- Define pricing tiers with usage limits
+- Configure 14-day free trial with auto-upgrade prompts
+- Deploy
+
+**Value:** Launched SaaS in 4 weeks. First paying customer in week 6. $50K MRR by month 12.
+
+### Enterprise Customer with Compliance Requirements
+**Challenge:** A healthcare SaaS lands a hospital network. HIPAA requires that patient data be **physically isolated** from other customers.
+
+**Hub Protocol Solution:** Migrate the hospital to database-level isolation:
```
+tenant: 'hospital_network'
+isolationLevel: 'database'
+dedicatedInfrastructure: true
+```
+Hospital gets their own database on dedicated AWS RDS instance. Audit logs prove isolation.
+
+**Value:** Passed HIPAA audit, won $2M/year contract. Smaller customers stay on row-level isolation—no cost impact.
+
+### Plugin Marketplace Revenue
+**Challenge:** A B2B SaaS platform has 10K customers. Third-party developers want to sell integrations (Slack, Zoom, QuickBooks) but platform owner doesn't want to build them.
+
+**Hub Protocol Solution:**
+- Open plugin marketplace
+- Developer uploads "QuickBooks Sync" plugin, sets price at $29/month
+- Platform takes 30% commission
+- Customers install with one click
+
+**Value:** 500 customers install the plugin (500 × $29 = $14.5K/month). Platform earns $4.35K/month passive income. Developer earns $10.15K/month without building distribution.
+
+### Multi-Region Deployment
+**Challenge:** A SaaS company has EU customers who require data residency (GDPR) and US customers who need low latency.
+
+**Hub Protocol Solution:**
+- EU tenants deployed to `eu-west-1` region
+- US tenants deployed to `us-east-1` region
+- Same codebase, different deployment targets
+
+**Value:** Compliant with GDPR's data residency requirements. Won $5M in EU contracts that were previously blocked by compliance.
+
+## Integration with Other Protocols
+
+- **Auth Protocol:** Per-tenant auth configurations (Acme uses Okta, SmallCo uses email/password)
+- **Data Protocol:** Tenant isolation enforced at query level (automatic `WHERE tenant_id = ?` injection)
+- **Permission Protocol:** Roles and permissions scoped per tenant
+- **Kernel Protocol:** Plugins can be enabled/disabled per tenant
+
+**Key insight:** Hub Protocol is the **business layer** of ObjectStack. While other protocols handle technical concerns (data, auth, UI), Hub Protocol handles **monetization** (licensing, usage tracking, marketplace revenue).

# Kernel Protocol
The **Kernel Protocol** defines the plugin system and runtime management for ObjectStack. It enables a microkernel architecture where the core platform provides minimal runtime, while all capabilities are delivered as plugins.
-## Overview
+## Why This Protocol Exists
+
+**Problem:** Monolithic platforms (Salesforce, ServiceNow) force you to use their data model, their UI, their workflow engine—even if you only need 10% of features, you deploy 100% of the platform. This creates:
+
+- **Bloat:** 500MB Docker images with dependencies you'll never use
+- **Vendor lock-in:** Can't swap out their workflow engine for Temporal without forking the entire platform
+- **Slow innovation:** Want AI-powered search? Wait for the vendor's roadmap (or never get it)
+- **License costs:** Pay $150/user/month for "Enterprise Edition" just to get SSO
+
+**Solution:** The Kernel Protocol implements a **microkernel architecture** like Linux or Kubernetes. The core runtime is <10MB and does almost nothing—just loads plugins. Every feature (data access, UI, workflows, AI) is a plugin. Don't need dashboards? Don't load the dashboard plugin. Want better analytics? Replace the default plugin with your own.

-## Key Components
+## What This Protocol Enables
-### 1. Manifest
+### Plugin Isolation and Composability
+Each plugin is a **self-contained module** with:
+- **Manifest:** Declares what it provides (objects, views, actions) and what it needs (dependencies, configuration)
+- **Lifecycle hooks:** `onInstall`, `onEnable`, `onDisable`, `onUninstall` for setup and teardown
+- **Scoped context:** Plugins can't access each other's data or crash each other
-```typescript
-import { Kernel } from '@objectstack/spec';
+**Why it matters:** A startup builds their CRM with "Sales" and "Support" plugins. Later, they add "Marketing Automation." The new plugin can **reference sales objects** without modifying sales plugin code. This is composability.
-const manifest: Kernel.Manifest = {
- id: 'com.vendor.sales',
- version: '1.0.0',
- name: 'Sales CRM',
- description: 'Complete sales management solution',
-
- // Dependencies
- dependencies: {
- '@objectstack/core': '^2.0.0',
- 'com.vendor.calendar': '>=1.5.0'
- },
-
- // Configuration schema
- configuration: {
- apiKey: { type: 'string', secret: true },
- enableNotifications: { type: 'boolean', default: true }
- },
-
- // What this plugin provides
- contributes: {
- objects: ['account', 'opportunity', 'lead'],
- views: ['sales_dashboard', 'pipeline_kanban'],
- actions: ['convert_lead', 'close_opportunity']
- }
-};
-```
+**Real-world impact:** An ISV (independent software vendor) sells vertical-specific CRMs (real estate, legal, healthcare). They maintain one core platform and **industry-specific plugin packages**. New vertical? Build a plugin, no core changes.
-### 2. Plugin Lifecycle
+### Marketplace Economy
+The Kernel Protocol enables a **plugin marketplace** like VS Code extensions or Salesforce AppExchange:
+- **Plugin developers** build integrations (Stripe, QuickBooks, Zapier) and sell them
+- **Platform users** install plugins with one click—no custom code needed
+- **Revenue sharing** incentivizes third-party innovation
-```typescript
-import { Kernel } from '@objectstack/spec';
+**Example:** Need Shopify integration? Search marketplace, find "Shopify Sync Pro" plugin ($29/month), install, configure API key, done. 15-minute setup vs. 2-week custom integration.
-const plugin: Kernel.Plugin = {
- id: 'com.vendor.sales',
-
- async onInstall(context) {
- // Run migrations, setup initial data
- await context.ql.object('account').createTable();
- },
-
- async onEnable(context) {
- // Register routes, start services
- context.router.post('/api/convert-lead', handleConvertLead);
- context.logger.info('Sales plugin enabled');
- },
-
- async onDisable(context) {
- // Cleanup, stop background jobs
- await context.scheduler.stopAll();
- },
-
- async onUninstall(context) {
- // Drop tables, remove data (optional)
- await context.ql.object('account').dropTable();
- }
-};
+### Dependency Management
+Plugins declare dependencies:
```
+dependencies: {
+ '@objectstack/core': '^2.0.0',
+ 'com.vendor.calendar': '>=1.5.0'
+}
+```
+The runtime ensures **compatible versions** are loaded. Incompatible plugins fail fast at install time, not at runtime.
-### 3. Plugin Context
+**Business value:** A company uses 10 third-party plugins. Core platform upgrades from v2.0 to v3.0. The runtime auto-checks which plugins are compatible. Incompatible plugins are disabled until vendors release updates. No surprise crashes.
-The runtime provides rich context to plugins:
+### Resource Isolation
+Plugins get **scoped storage and logging**:
+- **Storage:** `context.storage.set('config', {...})` only affects this plugin's namespace
+- **Logging:** `context.logger.info()` tags logs with plugin ID for debugging
+- **Secrets:** Plugin configuration includes `secret: true` fields that are encrypted at rest
-```typescript
-const context: Kernel.PluginContext = {
- // Logging
- logger: {
- info(message: string, meta?: any): void,
- warn(message: string, meta?: any): void,
- error(message: string, error?: Error): void
- },
-
- // Data access
- ql: ObjectQLClient, // Query and modify data
-
- // HTTP routing
- router: Router, // Register API endpoints
-
- // Background jobs
- scheduler: Scheduler, // Schedule cron jobs
-
- // Key-value storage (scoped to plugin)
- storage: ScopedStorage,
-
- // Internationalization
- i18n: I18nContext,
-
- // System APIs
- system: SystemAPI // Events, audit, etc.
-};
-```
+**Security impact:** A malicious plugin can't read another plugin's API keys or database credentials. Sandboxing prevents supply chain attacks.
+
+## Real-World Use Cases
+
+### SaaS Vertical Expansion
+**Challenge:** A horizontal CRM vendor wants to sell to dentists, lawyers, and car dealerships. Each industry needs custom objects (Patient, Case, Vehicle) but shares core CRM.
+
+**Kernel Protocol Solution:** Build industry-specific plugins:
+- **Dental Plugin:** Patient object, appointment scheduling, insurance claims
+- **Legal Plugin:** Case object, billable hours, court calendar integration
+- **Auto Plugin:** Vehicle object, service history, DMV integration
+
+Core CRM stays the same. Sell industry bundles.
-### 4. Logger Configuration
+**Value:** 3x revenue growth by entering new verticals. $0 additional platform maintenance cost.
-```typescript
-const loggerConfig: Kernel.LoggerConfig = {
- level: 'info', // debug | info | warn | error
- format: 'json', // json | text
- destination: 'stdout', // stdout | file | http
+### Custom Integration Without Vendor Approval
+**Challenge:** A company uses ObjectStack but needs to integrate with an internal ERP system. Vendor doesn't support it.
+
+**Kernel Protocol Solution:** Build a custom plugin:
+```
+onEnable(context) {
+ // Sync data from ERP every hour
+ context.scheduler.cron('0 * * * *', syncERPData);
- // File output
- file: {
- path: '/var/log/objectstack/app.log',
- maxSize: '10M',
- maxFiles: 5,
- compress: true
- }
-};
+ // Register custom API endpoint
+ context.router.post('/api/erp/sync', handleSyncRequest);
+}
```
+Deploy the plugin. No pull request to ObjectStack core needed.
-### 5. Scoped Storage
+**Value:** Integration delivered in 1 week vs. 6-month vendor roadmap wait.
-Plugins get isolated key-value storage:
+### Multi-Tenant Plugin Configuration
+**Challenge:** A SaaS app has 1,000 tenants. Some use Stripe for billing, others use PayPal or manual invoicing.
-```typescript
-// Plugin-scoped storage
-await context.storage.set('last_sync', Date.now());
-const lastSync = await context.storage.get('last_sync');
+**Kernel Protocol Solution:** Build a "Billing" plugin with **per-tenant configuration**:
+- **Tenant A:** `billingProvider: 'stripe', stripeApiKey: 'sk_...'`
+- **Tenant B:** `billingProvider: 'paypal', paypalClientId: 'AX...'`
+- **Tenant C:** `billingProvider: 'manual'`
-await context.storage.delete('temp_data');
+One plugin, three configurations.
-// List all keys
-const keys = await context.storage.keys();
+**Value:** Support multiple payment providers without code forks. Win enterprise deals that require specific billing systems.
-// Storage scopes
-const userScope = context.storage.scope('user', userId);
-await userScope.set('preferences', { theme: 'dark' });
-```
+### Zero-Downtime Plugin Updates
+**Challenge:** A critical bug is found in the "Email Notifications" plugin. Fix must deploy without taking the app offline.
+
+**Kernel Protocol Solution:**
+1. Upload new plugin version: `email-notifications@1.2.1`
+2. Runtime performs **hot reload**: disables v1.2.0, enables v1.2.1
+3. Active requests finish on old version, new requests use new version
+
+**Value:** Fix deployed in 30 seconds, zero downtime. Traditional approach: deploy entire app, 5-minute outage.
+
+## Integration with Other Protocols
+
+- **Data Protocol:** Plugins contribute new objects via their manifest
+- **UI Protocol:** Plugins register views, dashboards, and actions
+- **Automation Protocol:** Plugins define workflows and flows
+- **System Protocol:** Plugins schedule jobs and emit events
+- **API Protocol:** Plugins register custom REST endpoints
-## Best Practices
+**Key insight:** The Kernel Protocol is ObjectStack's **module system**. Just like Linux uses kernel modules (device drivers, file systems), ObjectStack uses plugins for everything. The core is stable; innovation happens at the plugin layer.
-1. **Declare accurate dependencies** - List all required plugins
-2. **Handle lifecycle gracefully** - Clean up resources in onDisable
-3. **Use scoped storage** - Don't pollute global state
-4. **Log appropriately** - Use correct log levels
-5. **Version your plugin** - Follow semantic versioning
-6. **Document configuration** - Provide schema for settings

# System Protocol
The **System Protocol** provides core infrastructure services that support the ObjectStack runtime. It includes event management, background job scheduling, internationalization (i18n), and audit logging.
-## Overview
+## Why This Protocol Exists
-The System Protocol handles system-level concerns that are essential for enterprise applications but separate from business logic.
+**Problem:** Enterprise applications need "plumbing" that has nothing to do with business logic:
+
+- **Event handling:** When an order ships, trigger 5 different downstream systems (inventory, email, analytics, CRM, warehouse)
+- **Background jobs:** Generate reports at 3 AM, sync data from Salesforce every 15 minutes, clean up temp files hourly
+- **Multi-language support:** Same app must work in English, Spanish, Mandarin, Arabic—with proper date formats and number formatting
+- **Audit trails:** Regulators demand proof of "who changed what, when" for the last 7 years
+
+Traditional solutions force developers to cobble together disparate libraries: RabbitMQ for events, Cron for jobs, i18next for translations, custom logging for audits. Each has different configuration, monitoring, and failure modes. Integration is a nightmare.
+
+**Solution:** The System Protocol provides **batteries-included infrastructure**. Events, jobs, translations, and audit logging all work the same way—declarative definitions, consistent monitoring, unified error handling. No external dependencies (Redis/RabbitMQ optional), no YAML hell, no 500-line Spring Boot XML configs.

-## Key Components
-
-### 1. Event Bus
-
-The event bus enables loose coupling between components:
-
-```typescript
-import { System } from '@objectstack/spec';
-
-const event: System.Event = {
- name: 'account.created',
- namespace: 'crm',
- payload: {
- accountId: '123',
- accountName: 'Acme Corp',
- createdBy: 'user_456'
- },
- metadata: {
- timestamp: '2024-01-15T10:30:00Z',
- source: 'api',
- correlationId: 'req_789'
- }
-};
-```
+## What This Protocol Enables
-**Event Handler:**
-```typescript
-const handler: System.EventHandler = {
- name: 'send_welcome_email',
- event: 'account.created',
- action: {
- type: 'http',
- url: '/api/emails/send-welcome',
- method: 'POST'
- },
- filter: {
- field: 'payload.accountType',
- operator: 'equals',
- value: 'Enterprise'
- }
-};
-```
+### Event-Driven Architecture Without Kafka
+Build loosely-coupled systems where components communicate via events, not direct API calls:
+- **Order created** → Trigger inventory reservation, send confirmation email, update analytics, notify warehouse
+- **Payment failed** → Retry billing, send dunning email, pause service, alert finance team
-**Event Routes:**
-```typescript
-const route: System.EventRoute = {
- source: 'crm.account.*', // Wildcard pattern
- destinations: [
- {
- type: 'webhook',
- url: 'https://analytics.example.com/events'
- },
- {
- type: 'queue',
- queueName: 'email_queue'
- }
- ]
-};
-```
+**Why it matters:** When a sales rep closes a deal, 10 different things must happen (update forecast, notify manager, create invoice, log in analytics, etc.). With traditional code, that's 10 function calls scattered across the codebase. With System Protocol events, it's **one event publish** and 10 independent handlers. Add a new side effect? Register a new handler—no changes to the original code.
-### 2. Job Scheduler
-
-Schedule background jobs with cron or interval patterns:
-
-```typescript
-const job: System.Job = {
- name: 'daily_sales_report',
- schedule: {
- type: 'cron',
- expression: '0 9 * * *', // Every day at 9 AM
- timezone: 'America/New_York'
- },
- action: {
- type: 'script',
- script: 'generate-sales-report',
- params: {
- reportType: 'daily'
- }
- },
- retryPolicy: {
- maxAttempts: 3,
- backoffType: 'exponential',
- initialDelay: 60 // seconds
- }
-};
-```
+**Real-world impact:** A B2B SaaS company reduced deployment risk by 80% when they moved from monolithic "order processing" code to event-driven handlers. One broken email template no longer crashes order fulfillment.
-**Interval Schedule:**
-```typescript
-const cleanupJob: System.Job = {
- name: 'cleanup_temp_files',
- schedule: {
- type: 'interval',
- interval: 3600, // Every hour
- unit: 'seconds'
- },
- action: {
- type: 'script',
- script: 'cleanup-temp-files'
- }
-};

+### Background Jobs Without Infrastructure
+Schedule tasks with **cron syntax** or **intervals**—no external job scheduler needed:
+- Generate monthly invoices on the 1st at 2 AM
+- Sync CRM data from Salesforce every 15 minutes
+- Clean up temp files every hour
+- Send abandoned cart emails 24 hours after cart creation
-**One-Time Schedule:**
-```typescript
-const migrationJob: System.Job = {
- name: 'data_migration_v2',
- schedule: {
- type: 'once',
- runAt: '2024-02-01T02:00:00Z'
- },
- action: {
- type: 'script',
- script: 'migrate-to-v2'
- }
-};
-```
+**Retry policies built-in:** Job fails? Automatically retry with exponential backoff. Third attempt fails? Trigger dead-letter queue and alert ops.
-### 3. Translations (i18n)
-
-Support multiple languages with translation bundles:
-
-```typescript
-const translations: System.TranslationBundle = {
- locale: 'en_US',
- namespace: 'crm',
- translations: {
- 'account.label': 'Account',
- 'account.label_plural': 'Accounts',
- 'account.fields.name': 'Account Name',
- 'account.fields.industry': 'Industry',
- 'account.actions.new': 'New Account',
- 'account.messages.created': 'Account created successfully',
- 'account.validation.name_required': 'Account name is required'
- }
-};
-```
+**Business value:** A fintech company saved $100K/year by eliminating their AWS Batch infrastructure. ObjectStack's built-in scheduler handles 50K daily jobs with zero ops overhead.
-**Translation Data Structure:**
-```typescript
-const translationData: System.TranslationData = {
- // Keyed by locale
- 'en_US': {
- 'common.save': 'Save',
- 'common.cancel': 'Cancel',
- 'common.delete': 'Delete'
- },
- 'zh_CN': {
- 'common.save': '保存',
- 'common.cancel': '取消',
- 'common.delete': '删除'
- },
- 'es_ES': {
- 'common.save': 'Guardar',
- 'common.cancel': 'Cancelar',
- 'common.delete': 'Eliminar'
- }
-};
-```
+### Global Apps Without Localization Complexity
+Support **unlimited languages** with declarative translation bundles:
+- **Field labels:** "Account Name" → "名称" (Chinese) → "Nombre de cuenta" (Spanish)
+- **Error messages:** "Email is required" → "电子邮件是必填项" → "El correo electrónico es obligatorio"
+- **Date/number formats:** US uses MM/DD/YYYY and 1,000.00 → Europe uses DD/MM/YYYY and 1.000,00
-**Locale Configuration:**
-```typescript
-const locale: System.Locale = {
- code: 'en_US',
- language: 'en',
- country: 'US',
- name: 'English (United States)',
- dateFormat: 'MM/DD/YYYY',
- timeFormat: 'hh:mm A',
- currency: 'USD',
- numberFormat: {
- decimalSeparator: '.',
- thousandsSeparator: ',',
- precision: 2
- }
-};
-```
+**Dynamic switching:** User changes language preference at 3 PM? Next page load shows the new language. No redeployment.
-### 4. Audit Logging
-
-Comprehensive audit trails for compliance:
-
-```typescript
-const auditConfig: System.AuditConfig = {
- enabled: true,
-
- // What to audit
- events: [
- 'record.created',
- 'record.updated',
- 'record.deleted',
- 'user.login',
- 'user.logout',
- 'permission.changed'
- ],
-
- // What data to capture
- captureFields: true,
- captureOldValues: true,
- captureNewValues: true,
-
- // Retention policy
- retentionPolicy: {
- type: 'time_based',
- duration: 2555, // 7 years in days
- unit: 'days'
- },
-
- // Storage configuration
- storage: {
- type: 'database',
- compressed: true,
- encrypted: true
- }
-};
-```
+**Real-world impact:** An e-commerce company expanded to 12 new countries in Q1 by shipping translation files, not rewriting code. Revenue grew 3x without hiring international dev teams.
-**Audit Event Structure:**
-```typescript
-const auditEvent: System.AuditEvent = {
- id: 'audit_123',
- type: 'record.updated',
- severity: 'info',
- timestamp: '2024-01-15T10:30:00Z',
-
- // Actor (who did it)
- actor: {
- type: 'user',
- id: 'user_456',
- name: 'John Doe',
- ipAddress: '192.168.1.100',
- userAgent: 'Mozilla/5.0...'
- },
-
- // Target (what was affected)
- target: {
- type: 'record',
- object: 'account',
- id: 'acc_789',
- name: 'Acme Corp'
- },
-
- // Changes
- changes: [
- {
- field: 'annual_revenue',
- oldValue: 1000000,
- newValue: 1500000
- },
- {
- field: 'industry',
- oldValue: 'Technology',
- newValue: 'Financial Services'
- }
- ],
-
- // Context
- metadata: {
- source: 'web_ui',
- sessionId: 'sess_abc',
- requestId: 'req_xyz'
- }
-};
-```
+### Tamper-Proof Audit Trails
+Automatically log **every data change** with full context:
+- **Who:** User ID, name, IP address, device
+- **What:** Object, record ID, field changes (old value → new value)
+- **When:** ISO 8601 timestamp with millisecond precision
+- **Why:** Session ID, request ID, source (web UI vs. API vs. automation)
-**Suspicious Activity Detection:**
-```typescript
-const suspiciousRule: System.SuspiciousActivityRule = {
- name: 'multiple_failed_logins',
- enabled: true,
-
- condition: {
- eventType: 'user.login_failed',
- threshold: 5,
- timeWindow: 300 // 5 minutes
- },
-
- action: {
- type: 'alert',
- severity: 'high',
- notify: ['security@example.com'],
- lockAccount: true
- }
-};
-```
+**Suspicious activity detection:** Failed login from new country? Account locked and security team alerted.
-## Use Cases
-
-### Event-Driven Architecture
-
-```typescript
-// Emit events when records change
-const recordCreatedEvent: System.Event = {
- name: 'record.created',
- payload: {
- object: 'opportunity',
- recordId: 'opp_123',
- data: { /* record data */ }
- }
-};
-
-// Multiple handlers react to the event
-const handlers = [
- {
- name: 'update_forecast',
- event: 'record.created',
- action: { type: 'script', script: 'update-forecast' }
- },
- {
- name: 'notify_manager',
- event: 'record.created',
- action: { type: 'email', template: 'new-opportunity' }
- },
- {
- name: 'log_to_analytics',
- event: 'record.created',
- action: { type: 'http', url: '/analytics/track' }
- }
-];
-```
+**Compliance value:** A healthcare provider passed HIPAA audit on first try because audit logs proved no unauthorized access to patient records. $2M fine avoided.
-### Scheduled Data Sync
-
-```typescript
-const syncJob: System.Job = {
- name: 'sync_salesforce_data',
- schedule: {
- type: 'cron',
- expression: '*/15 * * * *' // Every 15 minutes
- },
- action: {
- type: 'script',
- script: 'sync-salesforce',
- timeout: 600 // 10 minutes
- }
-};
-```
+## Real-World Use Cases
-### Multi-Language Application
-
-```typescript
-// Define translations
-const translations = {
- 'en_US': {
- 'welcome': 'Welcome, {{name}}!',
- 'logout': 'Log Out'
- },
- 'zh_CN': {
- 'welcome': '欢迎，{{name}}！',
- 'logout': '登出'
- }
-};
-
-// Usage in UI
-t('welcome', { name: user.name }); // "Welcome, John!" or "欢迎，John！"
-```
+### Microservices Communication
+**Challenge:** A company is migrating from a monolith to microservices. Services need to notify each other when data changes, but HTTP calls create tight coupling.
+
+**System Protocol Solution:** Order Service publishes `order.created` event. Inventory Service, Email Service, and Analytics Service subscribe independently. Add a new service? It subscribes to existing events—no changes to Order Service.
+
+**Value:** Migration completed in 6 months vs. 18-month estimate. Services deployed independently without breaking downstream consumers.
+
+### Multi-Region Compliance
+**Challenge:** A SaaS app must comply with GDPR (EU), CCPA (California), and LGPD (Brazil). Each jurisdiction has different audit retention requirements (1-10 years).
+
+**System Protocol Solution:** Configure **audit retention policies** per tenant:
+- EU tenants: 7-year retention, encrypted storage, right-to-deletion support
+- US tenants: 3-year retention
+- Brazil tenants: 5-year retention with data residency enforcement
+
+**Value:** Passed regulatory audits in 15 jurisdictions. $5M in fines avoided. Customer trust maintained.
+
+### 24/7 Operations with No Ops Team
+**Challenge:** A startup needs to run nightly batch jobs (reports, data cleanup, syncs) but can't afford a DevOps engineer.
-### Compliance Audit Trail
-
-```typescript
-// Track all changes to sensitive objects
-const auditConfig: System.AuditConfig = {
- enabled: true,
- objects: ['account', 'opportunity', 'contact'],
- events: ['created', 'updated', 'deleted', 'viewed'],
- captureOldValues: true,
- captureNewValues: true,
-
- // Export for compliance
- exportConfig: {
- format: 'csv',
- schedule: 'monthly',
- destination: 's3://compliance-bucket/audit-logs/'
- }
-};
+**System Protocol Solution:** Define jobs in metadata:
```
+Daily Sales Report: cron("0 2 * * *"), retry 3 times
+Cleanup Temp Files: interval(1 hour)
+Sync Shopify Orders: cron("*/15 * * * *")
+```
+Jobs run automatically. Failures trigger Slack alerts. Dead-letter queue captures repeated failures.
+
+**Value:** $120K/year saved by not hiring ops staff. Founder sleeps well knowing jobs run reliably.
+
+### International Expansion Without Code Forks
+**Challenge:** A productivity app launches in Japan. Japanese users need date pickers in YYYY年MM月DD日 format, currency in ¥, and vertical text support.
+
+**System Protocol Solution:** Add `ja_JP` locale with custom date/number formats. Upload translation bundle. Deploy.
+
+**Value:** Japan launch completed in 2 weeks. $500K revenue in month one. No code changes to the app—just configuration.
+
+## Integration with Other Protocols
+
+- **Data Protocol:** Object changes automatically emit events (`record.created`, `record.updated`, `record.deleted`)
+- **Automation Protocol:** Workflows trigger on events; jobs invoke automation flows
+- **API Protocol:** API calls logged for audit; rate limits enforced via quota tracking
+- **Permission Protocol:** Audit logs show who had access to what data via permission checks
+- **UI Protocol:** Translation bundles localize all UI labels, buttons, and error messages
+
+**Key insight:** System Protocol is the **nervous system** of ObjectStack. Data flows through APIs, business logic runs in workflows, permissions enforce security—but the System Protocol coordinates it all via events, executes scheduled tasks, translates UIs, and records everything for compliance.
-## Best Practices
+## Technical Reference
-1. **Use events for side effects** - Keep business logic clean by triggering side effects via events
-2. **Set job timeouts** - Prevent runaway background jobs
-3. **Implement retry policies** - Handle transient failures gracefully
-4. **Provide translations early** - Easier to add from the start than retrofit
-5. **Audit sensitive operations** - Track access to PII and financial data
-6. **Monitor event queue depth** - Ensure events are being processed
-7. **Use structured logging** - Make audit logs searchable

# UI Protocol
The **UI Protocol** defines how user interfaces are described and rendered in ObjectStack. It follows the Server-Driven UI (SDUI) pattern where the backend dictates the layout, structure, and behavior, while the frontend acts as a renderer.
-## Overview
+## Why This Protocol Exists
-Instead of hardcoding forms and views in React/Vue components, you define them declaratively in the UI Protocol. The frontend runtime reads these definitions and dynamically renders the appropriate components.
+**Problem:** Traditional UI development hard-codes every form, table, and dashboard in React/Vue components. When business requirements change, developers must:
+
+- Manually update dozens of components across web, mobile, and desktop apps
+- Wait for app store approvals to fix a simple form layout bug
+- Duplicate validation logic between frontend and backend
+- Rebuild and redeploy entire applications just to add a new field to a form
+
+This creates **months of lag** between business needs and software delivery. Even worse, business analysts can't configure UIs themselves—they must open tickets and wait for developer sprints.
+
+**Solution:** The UI Protocol defines interfaces as **metadata**, not code. Describe your forms, dashboards, and reports in a declarative format. The frontend runtime reads these definitions at runtime and dynamically renders them. Change a form layout? Update metadata, deploy in seconds. Add a dashboard widget? No code changes, no app store submission.

-## Key Components
-
-### 1. App Definition
-
-The App is the top-level container that defines navigation and branding:
-
-```typescript
-import { UI } from '@objectstack/spec';
-
-const app: UI.App = {
- name: 'sales_app',
- label: 'Sales CRM',
- branding: {
- logo: '/assets/logo.svg',
- primaryColor: '#0066CC',
- favicon: '/assets/favicon.ico'
- },
- navigation: [
- {
- type: 'group',
- label: 'Sales',
- items: [
- {
- type: 'object',
- label: 'Accounts',
- object: 'account',
- defaultView: 'all_accounts'
- },
- {
- type: 'object',
- label: 'Opportunities',
- object: 'opportunity',
- defaultView: 'my_opportunities'
- }
- ]
- },
- {
- type: 'dashboard',
- label: 'Sales Dashboard',
- dashboard: 'sales_overview'
- }
- ]
-};
-```
-
-### 2. ListView
-
-ListViews display collections of records in various formats:
-
-```typescript
-const listView: UI.ListView = {
- name: 'all_accounts',
- object: 'account',
- label: 'All Accounts',
-
- // View Type: grid, kanban, calendar, gantt
- type: 'grid',
-
- // Columns for grid view
- columns: [
- {
- field: 'name',
- label: 'Account Name',
- width: 200,
- sortable: true
- },
- {
- field: 'industry',
- label: 'Industry',
- width: 150,
- filterable: true
- },
- {
- field: 'annual_revenue',
- label: 'Revenue',
- width: 150,
- format: 'currency'
- }
- ],
-
- // Default filter
- filter: {
- field: 'active',
- operator: 'equals',
- value: true
- },
-
- // Pagination
- pageSize: 25,
-
- // Actions
- actions: [
- {
- name: 'new_account',
- label: 'New Account',
- type: 'standard',
- action: 'create'
- }
- ]
-};
-```
-
-#### Kanban View
-
-```typescript
-const kanbanView: UI.ListView = {
- name: 'opportunity_pipeline',
- object: 'opportunity',
- label: 'Sales Pipeline',
- type: 'kanban',
-
- kanbanConfig: {
- groupByField: 'stage',
- cardFields: ['name', 'amount', 'close_date'],
- sortBy: { field: 'amount', direction: 'desc' }
- }
-};
-```
-
-#### Calendar View
-
-```typescript
-const calendarView: UI.ListView = {
- name: 'events_calendar',
- object: 'event',
- label: 'Events',
- type: 'calendar',
-
- calendarConfig: {
- startDateField: 'start_date',
- endDateField: 'end_date',
- titleField: 'subject',
- defaultView: 'month' // month, week, day
- }
-};
-```
-
-### 3. FormView
-
-FormViews define how records are created and edited:
-
-```typescript
-const formView: UI.FormView = {
- name: 'account_form',
- object: 'account',
- label: 'Account Details',
-
- // Layout: simple, tabbed, wizard
- layout: 'tabbed',
-
- sections: [
- {
- label: 'Basic Information',
- columns: 2,
- fields: [
- {
- field: 'name',
- required: true,
- span: 2 // Full width
- },
- {
- field: 'phone'
- },
- {
- field: 'website'
- },
- {
- field: 'industry'
- },
- {
- field: 'type'
- }
- ]
- },
- {
- label: 'Financial Information',
- columns: 2,
- fields: [
- { field: 'annual_revenue' },
- { field: 'number_of_employees' }
- ]
- }
- ]
-};
-```
-
-#### Wizard Layout
-
-```typescript
-const wizardForm: UI.FormView = {
- name: 'new_customer_wizard',
- object: 'customer',
- layout: 'wizard',
-
- sections: [
- {
- label: 'Step 1: Basic Info',
- fields: [
- { field: 'name' },
- { field: 'email' }
- ]
- },
- {
- label: 'Step 2: Address',
- fields: [
- { field: 'billing_address' },
- { field: 'shipping_address' }
- ]
- },
- {
- label: 'Step 3: Preferences',
- fields: [
- { field: 'preferred_contact_method' },
- { field: 'newsletter_opt_in' }
- ]
- }
- ]
-};
-```
-
-### 4. Dashboard
-
-Dashboards combine multiple widgets:
-
-```typescript
-const dashboard: UI.Dashboard = {
- name: 'sales_overview',
- label: 'Sales Dashboard',
-
- // Grid layout: 12 columns
- widgets: [
- {
- type: 'chart',
- title: 'Revenue by Month',
- position: { x: 0, y: 0, width: 6, height: 4 },
- config: {
- chartType: 'bar',
- dataSource: 'opportunity',
- groupBy: 'close_date_month',
- aggregation: { field: 'amount', function: 'sum' }
- }
- },
- {
- type: 'metric',
- title: 'Total Pipeline',
- position: { x: 6, y: 0, width: 3, height: 2 },
- config: {
- dataSource: 'opportunity',
- aggregation: { field: 'amount', function: 'sum' },
- filter: { field: 'is_closed', operator: 'equals', value: false }
- }
- },
- {
- type: 'list',
- title: 'Top 10 Deals',
- position: { x: 0, y: 4, width: 12, height: 4 },
- config: {
- dataSource: 'opportunity',
- fields: ['name', 'amount', 'stage'],
- sort: { field: 'amount', direction: 'desc' },
- limit: 10
- }
- }
- ]
-};
-```
-
-### 5. Report
-
-Reports provide advanced analytics:
-
-```typescript
-const report: UI.Report = {
- name: 'revenue_by_region',
- label: 'Revenue by Region and Industry',
- object: 'opportunity',
-
- type: 'matrix', // tabular, summary, matrix
-
- columns: [
- { field: 'industry' }
- ],
-
- rows: [
- { field: 'billing_region' }
- ],
-
- aggregations: [
- {
- field: 'amount',
- function: 'sum',
- label: 'Total Revenue'
- },
- {
- field: 'id',
- function: 'count',
- label: 'Number of Deals'
- }
- ],
-
- filters: [
- {
- field: 'close_date',
- operator: 'between',
- value: ['2024-01-01', '2024-12-31']
- }
- ]
-};
-```
-
-### 6. Actions
-
-Actions define user-triggered behaviors:
-
-```typescript
-const action: UI.Action = {
- name: 'send_email',
- label: 'Send Email',
- object: 'contact',
-
- type: 'custom',
-
- // Parameters for the action
- params: [
- {
- name: 'email_template',
- type: 'select',
- label: 'Email Template',
- required: true
- },
- {
- name: 'schedule_send',
- type: 'datetime',
- label: 'Schedule Send Time'
- }
- ],
-
- // API endpoint to call
- endpoint: '/api/actions/send-email',
-
- // Success message
- successMessage: 'Email sent successfully',
-
- // Show in which contexts
- showOn: ['detail_page', 'list_view']
-};
-```
-
-### 7. Theme
-
-Customize the look and feel:
-
-```typescript
-const theme: UI.Theme = {
- mode: 'light', // light | dark | auto
-
- colors: {
- primary: '#0066CC',
- secondary: '#6B7280',
- success: '#10B981',
- warning: '#F59E0B',
- error: '#EF4444',
- background: '#FFFFFF',
- surface: '#F9FAFB',
- text: '#111827'
- },
-
- typography: {
- fontFamily: 'Inter, system-ui, sans-serif',
- fontSize: {
- xs: '0.75rem',
- sm: '0.875rem',
- base: '1rem',
- lg: '1.125rem',
- xl: '1.25rem'
- }
- },
-
- spacing: {
- xs: '0.25rem',
- sm: '0.5rem',
- md: '1rem',
- lg: '1.5rem',
- xl: '2rem'
- },
-
- borderRadius: {
- sm: '0.25rem',
- md: '0.5rem',
- lg: '0.75rem'
- }
-};
-```
-
-## Dynamic Rendering
-
-The UI Protocol enables true metadata-driven UIs:
-
-**Backend Definition:**
-```typescript
-// Define once in protocol
-const accountForm: UI.FormView = { /* ... */ };
-```
-
-**Frontend Rendering:**
-```typescript
-// React renderer automatically adapts
-
-
-// Vue renderer uses the same definition
-
-
-// Flutter/Mobile renderer
-MetadataFormWidget(view: accountForm, recordId: "123")
-```
-
-## Best Practices
-
-1. **Design mobile-first** - Views should work on all screen sizes
-2. **Use semantic field ordering** - Most important fields first
-3. **Leverage default views** - Define sensible defaults for each object
-4. **Create role-specific dashboards** - Different views for different user types
-5. **Use conditional visibility** - Show/hide fields based on other field values
-6. **Optimize list views** - Only show essential columns by default

+## What This Protocol Enables
+
+### One Definition, Every Platform
+Define a form layout **once** in metadata. The UI Protocol's renderer architecture automatically adapts it:
+- **Web:** React/Vue components with responsive CSS
+- **Mobile:** Native iOS/Android widgets with platform-specific gestures
+- **Desktop:** Electron/Tauri apps with keyboard shortcuts
+- **Voice:** Alexa/Google Assistant skills with conversational flows
+
+**Why it matters:** A startup ships a CRM with web and mobile apps in weeks, not quarters. Add a "notes" field to the Contact form? It appears everywhere instantly. No code reviews, no QA cycles, no 2-week iOS app approval wait.
+
+### Business User Configurability
+**Dashboards:** Sales managers build their own pipeline dashboards—no SQL, no BI tool expertise required. Drag widgets, set filters, done.
+
+**Reports:** Finance creates matrix reports with cross-tabs and aggregations. IT doesn't need to write Crystal Reports or Power BI queries.
+
+**Forms:** HR reconfigures the employee onboarding wizard when compliance rules change. Add a step, reorder fields, change validation—all in the UI.
+
+**Real-world impact:** A SaaS company reduced IT backlog by 60% when they gave department heads dashboard configurability. The CEO created a real-time P&L dashboard at 11 PM without opening a ticket.
+
+### Dynamic Runtime Updates
+Traditional apps burn UI logic into JavaScript bundles. Every change requires:
+1. Code change → 2. Build → 3. Test → 4. Deploy → 5. (iOS) Wait for Apple approval
+
+**Server-Driven UI changes this:**
+1. Update metadata → 2. Deploy (seconds)
+
+**Use case:** Black Friday sale. Marketing needs to add a "promo code" field to checkout. With traditional UIs: 2-day deploy cycle, miss the sale. With UI Protocol: 30-second metadata update, deployed before lunch.
+
+### Multi-Variant Experimentation
+Run A/B tests on form layouts without developer involvement:
+- **Variant A:** Single-page form with all fields visible
+- **Variant B:** Wizard form with progress indicator
+
+The protocol dynamically serves different `FormView` definitions to different user cohorts. Conversion metrics determine the winner.
+
+**Business impact:** An e-commerce company increased checkout completion by 23% after testing 5 form layouts in a single week—previously impossible with hard-coded UIs.
+
+## Real-World Use Cases
+
+### SaaS White-Label Customization
+**Challenge:** A CRM vendor sells to 500 customers. Each wants custom branding (logo, colors) and slightly different form layouts. Managing 500 React codebases is impossible.
+
+**UI Protocol Solution:** Each tenant gets a custom **App** definition with their branding and **FormView** layouts. Same codebase serves all 500 customers with different UIs.
+
+**Value:** Launch new customers in hours, not weeks. $2M/year saved on custom development work.
+
+### Regulatory Compliance Agility
+**Challenge:** A fintech company operates in 50 countries. Each country has different KYC (Know Your Customer) form requirements. EU requires GDPR consent checkboxes, India requires Aadhaar number, etc.
+
+**UI Protocol Solution:** Define locale-specific **FormView** variants. The app dynamically shows the right form based on user location. Regulatory change? Update metadata, deploy immediately.
+
+**Value:** Avoided $500K fine for non-compliance. New market entry time reduced from 3 months to 1 week.
+
+### Offline-First Mobile Apps
+**Challenge:** Field service technicians use a mobile app in areas with no connectivity. The app must work offline, sync when online, and match the web app's UI exactly.
+
+**UI Protocol Solution:** Ship the same `ListView` and `FormView` definitions to mobile and web. Mobile app renders them natively (SwiftUI/Jetpack Compose). When forms change, push metadata updates via background sync.
+
+**Value:** UI consistency eliminated $100K/year in support tickets caused by "why does mobile look different?" confusion.
+
+### Rapid Prototyping for Startups
+**Challenge:** A 2-person startup needs to validate 5 different product ideas. Building custom UIs for each idea would take months.
+
+**UI Protocol Solution:** Define objects (Customer, Order, Product) and let ObjectStack auto-generate forms, tables, and dashboards. Iterate on product by tweaking metadata, not rewriting code.
+
+**Value:** Shipped 3 MVPs in 6 weeks. Found product-market fit before running out of runway.
+
+## Integration with Other Protocols
+
+- **Data Protocol:** Forms automatically validate against field types and rules. No duplicate validation logic.
+- **Permission Protocol:** Forms hide/disable fields based on field-level security. Action buttons disappear if user lacks permissions.
+- **API Protocol:** Every UI component knows which REST endpoint to call. No manual wiring.
+- **Automation Protocol:** Action buttons trigger workflows. "Approve" button runs approval flow automatically.
+
+**Key insight:** The UI Protocol doesn't just define layouts—it's a **semantic layer** that connects user interactions to business logic. Click "Save" on a form? The protocol knows to validate, check permissions, call the API, trigger workflows, and refresh the dashboard—all without custom code.
