-# WHOOSH - Autonomous AI Development Teams
+# WHOOSH – Council & Team Orchestration (Beta)
 
-WHOOSH is the orchestration platform for autonomous AI development teams in the CHORUS ecosystem. It transforms from a simple project template tool into a sophisticated system that enables AI agents to form optimal teams, collaborate democratically, and deliver high-quality solutions through consensus-driven development processes.
+WHOOSH assembles kickoff councils from Design Brief issues and is evolving toward autonomous team orchestration across the CHORUS stack. Council formation/deployment works today, but persistence, telemetry, and self-organising teams are still under construction.
 
-## 🎯 MVP Goals
+## Current Capabilities
 
-The current MVP focuses on:
+- ✅ Gitea Design Brief detection + council composition (`internal/monitor`, `internal/composer`).
+- ✅ Docker Swarm agent deployment with role-specific env vars (`internal/orchestrator`).
+- ✅ JWT authentication, rate limiting, OpenTelemetry hooks.
+- 🚧 API persistence: REST handlers still return placeholder data while Postgres wiring is finished (`internal/server/server.go`).
+- 🚧 Analysis ingestion: composer relies on heuristic classification; LLM/analysis ingestion is logged but unimplemented (`internal/composer/service.go`).
+- 🚧 Deployment telemetry: results aren’t persisted yet; monitoring includes TODOs for task details (`internal/monitor/monitor.go`).
+- 🚧 Autonomous teams: joining/role balancing planned but not live.
 
-1. **Single-Agent Execution**: Process `bzzz-task` labeled issues with single-agent teams
-2. **GITEA Integration**: Webhook handling for task discovery and PR management  
-3. **Basic Team Management**: Minimal team state tracking and assignment
-4. **SLURP Integration**: Artifact submission and retrieval proxy
-5. **Docker Swarm Deployment**: Production-ready containerization
+The full plan and sequencing live in:
+- `docs/progress/WHOOSH-roadmap.md`
+- `docs/DEVELOPMENT_PLAN.md`
 
-## 🏗️ Architecture
-
-### Core Components
-
-- **Go Backend**: HTTP server with chi/echo framework, structured logging with zerolog
-- **PostgreSQL Database**: Team, agent, and task state management with migrations
-- **GITEA Integration**: Webhook processing and API client for issue management
-- **Docker Swarm**: Production deployment with secrets management
-- **Redis**: Optional caching and session management
-
-### MVP Workflow
-
-1. GITEA webhook receives issue with `bzzz-task` label
-2. WHOOSH parses task information and creates team assignment
-3. Single-agent executor processes task (stubbed Team Composer)
-4. Results submitted via SLURP proxy for artifact preservation
-5. PR creation and status updates back to GITEA
-
-## 🚀 Quick Start
-
-### Local Development
+## Quick Start
 
 ```bash
-# Clone repository
 git clone https://gitea.chorus.services/tony/WHOOSH.git
 cd WHOOSH
-
-# Copy environment configuration
 cp .env.example .env
-# Edit .env with your configuration
-
-# Start with Docker Compose
-docker-compose up -d
-
-# Or run locally
+# Update DB, JWT, Gitea tokens
+make migrate
 go run ./cmd/whoosh
 ```
 
-### Production Deployment
+By default the API runs on `:8080` and expects Postgres + Docker Swarm in the environment. Until persistence lands, project/council endpoints return mock payloads to keep the UI working.
 
-```bash
-# Setup Docker Swarm secrets
-./scripts/setup-secrets.sh
+## Roadmap Snapshot
 
-# Deploy to swarm
-./scripts/deploy-swarm.sh v0.1.0-mvp
-```
+1. **Data path hardening** – replace mock handlers with real Postgres reads/writes.
+2. **Telemetry** – Persist deployment outcomes, emit KACHING events, build dashboards.
+3. **Autonomous loop** – Drive team formation/joining from composer outputs, tighten HMMM collaboration.
+4. **UX & governance** – Admin dashboards, compliance hooks, Decision Records.

+# Security Policy
+
+## Overview
+
+WHOOSH implements enterprise-grade security controls to protect against common web application vulnerabilities and ensure safe operation in production environments. This document outlines our security implementation, best practices, and procedures.
+
+## 🔐 Security Implementation
+
+### Authentication & Authorization
+
+**JWT Authentication**
+- Role-based access control (admin/user roles)
+- Configurable token expiration (default: 24 hours)
+- Support for file-based and environment-based secrets
+- Secure token validation with comprehensive error handling
+
+**Service Token Authentication**
+- Internal service-to-service authentication
+- Scoped permissions for automated systems
+- Support for multiple service tokens
+- Configurable token management
+
+**Protected Endpoints**
+All administrative endpoints require proper authentication:
+- Council management (`/api/v1/councils/*/artifacts`)
+- Repository operations (`/api/v1/repositories/*`)
+- Team management (`/api/v1/teams/*`)
+- Task ingestion (`/api/v1/tasks/ingest`)
+- Project operations (`/api/v1/projects/*`)
+
+### Input Validation & Sanitization
+
+**Comprehensive Input Validation**
+- Regex-based validation for all input types
+- Request body size limits (1MB default, 10MB for webhooks)
+- UUID validation for all identifiers
+- Safe character restrictions for names and titles
+
+**Validation Rules**
+```go
+Project Names:    ^[a-zA-Z0-9\s\-_]+$           (max 100 chars)
+Git URLs:         Proper URL format validation
+Task Titles:      Safe characters only           (max 200 chars)
+Agent IDs:        ^[a-zA-Z0-9\-]+$             (max 50 chars)
+UUIDs:           RFC 4122 compliant format
+```
+
+**Injection Prevention**
+- SQL injection prevention through parameterized queries
+- XSS prevention through input sanitization
+- Command injection prevention through input validation
+- Path traversal prevention through path sanitization
+
+### CORS Configuration
+
+**Production-Safe CORS**
+- No wildcard origins in production
+- Configurable allowed origins via environment variables
+- Support for file-based origin configuration
+- Restricted allowed headers and methods
+
+**Configuration Example**
+```bash
+# Production CORS configuration
+WHOOSH_CORS_ALLOWED_ORIGINS=https://app.company.com,https://admin.company.com
+WHOOSH_CORS_ALLOWED_METHODS=GET,POST,PUT,DELETE,OPTIONS
+WHOOSH_CORS_ALLOWED_HEADERS=Authorization,Content-Type,X-Requested-With
+WHOOSH_CORS_ALLOW_CREDENTIALS=true
+```
+
+### Rate Limiting
+
+**Per-IP Rate Limiting**
+- Default: 100 requests per minute per IP address
+- Configurable limits and time windows
+- Automatic cleanup to prevent memory leaks
+- Support for proxy headers (X-Forwarded-For, X-Real-IP)
+
+**Configuration**
+```bash
+WHOOSH_RATE_LIMIT_ENABLED=true
+WHOOSH_RATE_LIMIT_REQUESTS=100        # Requests per window
+WHOOSH_RATE_LIMIT_WINDOW=60s          # Rate limiting window
+WHOOSH_RATE_LIMIT_CLEANUP_INTERVAL=300s  # Cleanup frequency
+```
+
+### Security Headers
+
+**HTTP Security Headers**
+```
+Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'
+X-Frame-Options: DENY
+X-Content-Type-Options: nosniff
+X-XSS-Protection: 1; mode=block
+Referrer-Policy: strict-origin-when-cross-origin
+```
+
+### Webhook Security
+
+**Gitea Webhook Protection**
+- HMAC SHA-256 signature validation
+- Timing-safe signature comparison using `hmac.Equal`
+- Request body size limits (10MB maximum)
+- Content-Type header validation
+- Comprehensive attack attempt logging
+
+**Configuration**
+```bash
+WHOOSH_WEBHOOK_SECRET_FILE=/run/secrets/webhook_secret
+WHOOSH_MAX_WEBHOOK_SIZE=10485760  # 10MB
+```
+
+## 🛡️ Security Best Practices
+
+### Production Deployment
+
+**Secret Management**
+```bash
+# Use file-based secrets in production
+WHOOSH_JWT_SECRET_FILE=/run/secrets/jwt_secret
+WHOOSH_GITEA_TOKEN_FILE=/run/secrets/gitea_token
+WHOOSH_WEBHOOK_SECRET_FILE=/run/secrets/webhook_secret
+
+# Docker Swarm secrets example
+echo "strong-jwt-secret-32-chars-min" | docker secret create whoosh_jwt_secret -
+```
+
+**Database Security**
+```bash
+# Use SSL/TLS for database connections
+WHOOSH_DATABASE_URL=postgres://user:pass@host/db?sslmode=require
+
+# Connection pool limits
+WHOOSH_DB_MAX_OPEN_CONNS=25
+WHOOSH_DB_MAX_IDLE_CONNS=10
+WHOOSH_DB_CONN_MAX_LIFETIME=300s
+```
+
+**TLS Configuration**
+```bash
+# Enable TLS in production
+WHOOSH_TLS_ENABLED=true
+WHOOSH_TLS_CERT_FILE=/path/to/cert.pem
+WHOOSH_TLS_KEY_FILE=/path/to/key.pem
+WHOOSH_TLS_MIN_VERSION=1.2
+```
+
+### Security Monitoring
+
+**Logging & Monitoring**
+- Structured logging with security event correlation
+- Failed authentication attempt monitoring
+- Rate limit violation alerting
+- Administrative action audit logging
+
+**Health & Security Endpoints**
+- `/health` - Basic health check (unauthenticated)
+- `/admin/health/details` - Detailed system status (authenticated)
+- `/metrics` - Prometheus metrics (unauthenticated)
+
+### Access Control
+
+**Role-Based Permissions**
+- **Admin Role**: Full system access, administrative operations
+- **User Role**: Read-only access to public endpoints
+- **Service Tokens**: Scoped access for internal services
+
+**Endpoint Protection Matrix**

+
+**Date:** 2025-09-12  
+**Auditor:** Claude Code Security Expert  
+**Version:** Post-Security Hardening  
+
+## Executive Summary
+
+A comprehensive security audit was conducted on the WHOOSH search and indexing system. Multiple critical and high-risk vulnerabilities were identified and remediated, including CORS misconfiguration, missing authentication controls, inadequate input validation, and insufficient webhook security. The system now implements production-grade security controls following industry best practices.
+
+## Security Improvements Implemented
+
+### 1. CORS Configuration Hardening (CRITICAL - FIXED)
+
+**Issue:** Wildcard CORS origins (`AllowedOrigins: ["*"]`) allowed any domain to make authenticated requests.
+
+**Remediation:**
+- Implemented configurable CORS origins via environment variables
+- Added support for secret file-based configuration
+- Restricted allowed headers to only necessary ones
+- Updated configuration in `/internal/config/config.go` and `/internal/server/server.go`
+
+**Files Modified:**
+- `/internal/config/config.go`: Added `AllowedOrigins` and `AllowedOriginsFile` fields
+- `/internal/server/server.go`: Updated CORS configuration to use config values
+- `.env.example`: Added CORS configuration examples
+
+### 2. Authentication Middleware Implementation (HIGH - FIXED)
+
+**Issue:** Admin endpoints (team creation, project creation, repository management, council operations) lacked authentication controls.
+
+**Remediation:**
+- Created comprehensive authentication middleware supporting JWT and service tokens
+- Implemented role-based access control (admin vs regular users)
+- Added service token validation for internal services
+- Protected sensitive endpoints with appropriate middleware
+
+**Files Created:**
+- `/internal/auth/middleware.go`: Complete authentication middleware implementation
+
+**Files Modified:**
+- `/internal/server/server.go`: Added auth middleware to admin endpoints
+
+**Protected Endpoints:**
+- `POST /api/v1/teams` - Team creation (Admin required)
+- `PUT /api/v1/teams/{teamID}/status` - Team status updates (Admin required)
+- `POST /api/v1/tasks/ingest` - Task ingestion (Service token required)
+- `POST /api/v1/projects` - Project creation (Admin required)
+- `DELETE /api/v1/projects/{projectID}` - Project deletion (Admin required)
+- `POST /api/v1/repositories` - Repository creation (Admin required)
+- `PUT /api/v1/repositories/{repoID}` - Repository updates (Admin required)
+- `DELETE /api/v1/repositories/{repoID}` - Repository deletion (Admin required)
+- `POST /api/v1/repositories/{repoID}/sync` - Repository sync (Admin required)
+- `POST /api/v1/repositories/{repoID}/ensure-labels` - Label management (Admin required)
+- `POST /api/v1/councils/{councilID}/artifacts` - Council artifact creation (Admin required)
+
+### 3. Input Validation Enhancement (MEDIUM - FIXED)
+
+**Issue:** Basic validation with potential for injection attacks and malformed data processing.
+
+**Remediation:**
+- Implemented comprehensive input validation package
+- Added regex-based validation for all input types
+- Implemented request body size limits (1MB default, 10MB for webhooks)
+- Added sanitization functions to prevent injection attacks
+- Enhanced validation for projects, tasks, and agent registration
+
+**Files Created:**
+- `/internal/validation/validator.go`: Comprehensive validation framework
+
+**Files Modified:**
+- `/internal/server/server.go`: Updated project creation handler to use enhanced validation
+
+**Validation Rules Added:**
+- Project names: Alphanumeric + spaces/hyphens/underscores (max 100 chars)
+- Git URLs: Proper URL format validation
+- Task titles: Safe characters only (max 200 chars)
+- Agent IDs: Alphanumeric + hyphens (max 50 chars)
+- UUID validation for IDs
+- Request body size limits
+
+### 4. Webhook Security Strengthening (MEDIUM - ENHANCED)
+
+**Issue:** Webhook validation was basic but functional. Enhanced for production readiness.
+
+**Remediation:**
+- Added request body size limits (10MB max)
+- Enhanced signature validation with better error handling
+- Added Content-Type header validation
+- Implemented attack attempt logging
+- Added empty payload validation
+
+**Files Modified:**
+- `/internal/gitea/webhook.go`: Enhanced security validation
+
+**Security Features:**
+- HMAC SHA256 signature validation (already present, enhanced)
+- Timing-safe signature comparison using `hmac.Equal`
+- Request size limits to prevent DoS
+- Content-Type validation
+- Comprehensive error handling and logging
+
+### 5. Security Headers Implementation (MEDIUM - ADDED)
+
+**Issue:** Missing security headers leaving application vulnerable to common web attacks.
+
+**Remediation:**
+- Implemented comprehensive security headers middleware
+- Added Content Security Policy (CSP)
+- Implemented X-Frame-Options, X-Content-Type-Options, X-XSS-Protection
+- Added Referrer-Policy for privacy protection
+
+**Security Headers Added:**
+```
+Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'
+X-Frame-Options: DENY
+X-Content-Type-Options: nosniff
+X-XSS-Protection: 1; mode=block
+Referrer-Policy: strict-origin-when-cross-origin
+```
+
+### 6. Rate Limiting Implementation (LOW - ADDED)
+
+**Issue:** No rate limiting allowing potential DoS attacks.
+
+**Remediation:**
+- Implemented in-memory rate limiter with automatic cleanup
+- Set default limit: 100 requests per minute per IP
+- Added proper HTTP headers for rate limit information
+- Implemented client IP extraction with proxy support
+
+**Files Created:**
+- `/internal/auth/ratelimit.go`: Complete rate limiting implementation
+
+**Rate Limiting Features:**
+- Per-IP rate limiting
+- Configurable request limits and time windows
+- Automatic bucket cleanup to prevent memory leaks
+- Support for X-Forwarded-For and X-Real-IP headers
+- Proper HTTP status codes and headers
+
+## Security Configuration
+
+### Environment Variables
+
+Updated `.env.example` with security-focused configuration:
+
+```bash
+# CORS Origins (restrict to specific domains)
+WHOOSH_SERVER_ALLOWED_ORIGINS=https://your-frontend-domain.com,http://localhost:3000
+
+# Strong authentication secrets (use files in production)
+WHOOSH_AUTH_JWT_SECRET=your_jwt_secret_here_minimum_32_characters
+WHOOSH_AUTH_SERVICE_TOKENS=token1,token2,token3
+
+# File-based secrets for production
+WHOOSH_AUTH_JWT_SECRET_FILE=/secrets/jwt_secret
+WHOOSH_AUTH_SERVICE_TOKENS_FILE=/secrets/service_tokens
+WHOOSH_SERVER_ALLOWED_ORIGINS_FILE=/secrets/allowed_origins
+```
+
+### Production Recommendations
+
+1. **Secret Management:**
+   - Use file-based configuration for all secrets
+   - Implement secret rotation policies
+   - Store secrets in secure volumes (Docker secrets, Kubernetes secrets)
+
+2. **TLS Configuration:**
+   - Enable HTTPS in production
+   - Use strong TLS configuration (TLS 1.2+)
+   - Implement HSTS headers
+
+3. **Database Security:**
+   - Enable SSL/TLS for database connections
+   - Use dedicated database users with minimal privileges
+   - Implement database connection pooling limits
+
+4. **Monitoring:**
+   - Monitor authentication failures
+   - Alert on rate limit violations
+   - Log all administrative actions
+
+## Risk Assessment
+
+### Before Security Hardening
+- **Critical Risk:** CORS wildcard allowing unauthorized cross-origin requests
+- **High Risk:** Unprotected admin endpoints allowing unauthorized operations
+- **Medium Risk:** Basic input validation susceptible to injection attacks
+- **Medium Risk:** Minimal webhook security validation
+
+### After Security Hardening
+- **Low Risk:** Well-configured CORS with specific domains
+- **Low Risk:** Comprehensive authentication and authorization controls
+- **Low Risk:** Production-grade input validation and sanitization
+- **Low Risk:** Enhanced webhook security with comprehensive validation
+
+## Compliance Considerations
+
+The implemented security controls support compliance with:
+
+- **SOC 2 Type II:** Access controls, system monitoring, data protection
+- **ISO 27001:** Information security management system requirements
+- **NIST Cybersecurity Framework:** Identify, Protect, Detect functions
+- **OWASP Top 10:** Protection against most common web vulnerabilities
+
+## Testing Recommendations
+
+1. **Penetration Testing:**
+   - Test authentication bypass attempts
+   - Validate rate limiting effectiveness
+   - Test input validation with malicious payloads
+
+2. **Security Scanning:**
+   - Run OWASP ZAP or similar tools
+   - Perform static code analysis
+   - Conduct dependency vulnerability scanning
+
+3. **Monitoring:**
+   - Implement security event logging
+   - Set up alerting for suspicious activities
+   - Regular security metrics review
+
+## Conclusion
+
+The WHOOSH application has been significantly hardened with production-grade security controls. All identified vulnerabilities have been remediated, and the system now implements defense-in-depth security measures. Regular security assessments and monitoring should be maintained to ensure ongoing security posture.
+
+**Risk Reduction:** Critical and High risks eliminated, Medium risks reduced to Low
+**Security Posture:** Moved from Development/Testing to Production-Ready
+**Compliance Readiness:** Enhanced for enterprise compliance requirements

+Current Understanding
+
+  Based on your clarifications, I now understand that:
+  - CHORUS is fully featured: All agent functionality, consensus, elections, HMMM protocol, and output generation already exist
+  - Role parameterization: CHORUS reads prompts from human-roles.yaml based on role identifier parameter
+  - P2P Network: HMMM protocol runs on existing P2P network infrastructure
+  - Output formats: DRs and UCXL are well-defined, council determines specifics per-project
+  - The gap: WHOOSH deploys containers but doesn't properly wire CHORUS execution with parameters
+
+  Revised Implementation Plan
+
+  Phase 1: Core Parameter Wiring (MVP - Highest Priority)
+
+  1.1 Role Identifier Parameter
+
+  - Current Issue: CHORUS containers deploy without role identification
+  - Solution: Modify internal/orchestrator/agent_deployer.go to pass role parameter
+  - Implementation:
+    - Add CHORUS_ROLE environment variable with role identifier (e.g., "systems-analyst")
+    - CHORUS will automatically load corresponding prompt from human-roles.yaml
+
+  1.2 Design Brief Content Delivery
+
+  - Current Issue: CHORUS agents don't receive the Design Brief issue content
+  - Solution: Extract and pass Design Brief content as task context
+  - Implementation:
+    - Add CHORUS_TASK_CONTEXT environment variable with issue title, body, labels
+    - Include repository metadata and project context
+
+  1.3 CHORUS Agent Process Verification
+
+  - Current Issue: Containers may deploy but not execute CHORUS properly
+  - Solution: Verify container entrypoint and command configuration
+  - Implementation:
+    - Ensure CHORUS agent starts with correct parameters
+    - Verify container image and execution path
+
+  Phase 2: Network & Access Integration (Medium Priority)
+
+  2.1 P2P Network Configuration
+
+  - Current Issue: Council agents need access to HMMM P2P network
+  - Solution: Ensure proper network configuration for P2P discovery
+  - Implementation:
+    - Verify agents can connect to existing P2P infrastructure
+    - Add necessary network policies and service discovery
+
+  2.2 Repository Access
+
+  - Current Issue: Agents need repository access for cloning and operations
+  - Solution: Provide repository credentials and context
+  - Implementation:
+    - Mount Gitea token as secret or environment variable
+    - Provide CHORUS_REPO_URL with clone URL
+    - Add CHORUS_REPO_NAME for context
+
+  Phase 3: Lifecycle Management (Lower Priority)
+
+  3.1 Council Completion Detection
+
+  - Current Issue: No detection when council completes its work
+  - Solution: Monitor for council outputs and consensus completion
+  - Implementation:
+    - Watch for new Issues with bzzz-task labels created by council
+    - Monitor for Pull Requests with scaffolding
+    - Add consensus completion signals from CHORUS
+
+  3.2 Container Cleanup
+
+  - Current Issue: Council containers persist after completion
+  - Solution: Automatic cleanup when work is done
+  - Implementation:
+    - Remove containers when completion is detected
+    - Clean up associated resources and networks
+    - Log completion and transition events
+
+  Phase 4: Transition to Dynamic Teams (Future)
+
+  4.1 Task Team Formation Trigger
+
+  - Current Issue: No automatic handoff from council to task teams
+  - Solution: Detect council outputs and trigger dynamic team formation
+  - Implementation:
+    - Monitor for new bzzz-task issues created by council
+    - Trigger existing WHOOSH dynamic team formation
+    - Ensure proper context transfer
+
+  Key Implementation Focus
+
+  Environment Variables for CHORUS Integration
+
+  environment:
+    - CHORUS_ROLE=${role_identifier}           # e.g., "systems-analyst"  
+    - CHORUS_TASK_CONTEXT=${design_brief}      # Issue title, body, labels
+    - CHORUS_REPO_URL=${repository_clone_url}  # For repository access
+    - CHORUS_REPO_NAME=${repository_name}      # Project context
+
+  Expected Workflow (Clarification Needed)
+
+  1. WHOOSH Detection: Detects "Design Brief" issue with chorus-entrypoint + bzzz-task labels
+  2. Council Deployment: Deploys 8 CHORUS containers with role parameters
+  3. CHORUS Execution: Each agent loads role prompt, receives Design Brief content
+  4. Council Operation: Agents use HMMM protocol for communication and consensus
+  5. Output Generation: Council produces DRs as Issues and scaffolding as PRs
+  6. Completion & Cleanup: WHOOSH detects completion and removes containers
+  7. Team Formation: New bzzz-task issues trigger dynamic team formation
+
+  Questions for Clarification
+
+  1. CHORUS Container Configuration
+
+  - Question: What is the exact CHORUS container image and entrypoint?
+  - Context: Need to verify the container is executing CHORUS properly
+  - Example: Is it anthonyrawlins/chorus:latest with specific command parameters?
+
+  2. CHORUS Parameter Format
+
+  - Question: What is the exact parameter format CHORUS expects?
+  - Context: How does CHORUS receive role identifier and task context?
+  - Example: Environment variables, command line args, config files?
+
+  3. P2P Network Access
+
+  - Question: How do council agents connect to the existing P2P network?
+  - Context: What network configuration or service discovery is needed?
+  - Example: Specific ports, network policies, or discovery mechanisms?
+
+  4. Council Completion Signal
+
+  - Question: How does CHORUS signal when council work is complete?
+  - Context: What should WHOOSH monitor to detect completion?
+  - Example: Specific consensus events, file outputs, or API calls?
+
+  5. Repository Access Method
+
+  - Question: How should CHORUS agents access the project repository?
+  - Context: What credentials and access method does CHORUS expect?
+  - Example: Token in environment variable, mounted secret, or API key?
+
+  6. Council Size and Roles
+
+  - Question: Should all 8 roles always be deployed, or is it configurable?
+  - Context: Some projects might need different council compositions
+  - Example: Small projects might only need 4-5 roles, large ones might need additional specialists?
+
+  7. Design Brief Content Format
+
+  - Question: What format does CHORUS expect for the Design Brief content?
+  - Context: How should issue title, body, and metadata be structured?
+  - Example: JSON object, plain text, or specific format?
+
+  Current Implementation Gaps Summary
+
+  The main gap is parameter wiring between WHOOSH's council deployment and CHORUS's agent execution. All the complex functionality
+  (consensus, communication, output generation) already exists in CHORUS - we just need to properly configure the containers to
+  execute CHORUS with the right parameters.
+
+  This should be a relatively small implementation focused on:
+  1. Container Configuration: Proper environment variables and execution parameters
+  2. Content Extraction: Getting Design Brief content from Gitea to CHORUS
+  3. Network Setup: Ensuring P2P access for council communication
+  4. Lifecycle Management: Basic completion detection and cleanup
+
+  The heavy lifting (agent logic, consensus, outputs) is already done in CHORUS.
+
+  Todos
+  ☐ Wire role identifier parameter to CHORUS containers for council agents
+  ☐ Pass Design Brief content as task context to CHORUS agents
+  ☐ Ensure CHORUS agent process starts correctly in deployed containers
+  ☐ Verify P2P network access for council agents
+  ☐ Add completion detection and container cleanup logic

+
+## 🔧 Configuration Validation
+
+WHOOSH validates configuration on startup and provides detailed error messages for invalid settings:
+
+### Required Variables
+- `WHOOSH_DATABASE_URL` or individual DB components
+- `WHOOSH_GITEA_URL`
+- `WHOOSH_GITEA_TOKEN` or `WHOOSH_GITEA_TOKEN_FILE`
+
+### Common Validation Errors
+
+```bash
+# Invalid database URL
+ERROR: Invalid database URL format
+
+# Missing secrets
+ERROR: JWT secret not found. Set WHOOSH_JWT_SECRET or WHOOSH_JWT_SECRET_FILE
+
+# Invalid CORS configuration
+ERROR: CORS wildcard (*) not allowed in production. Set specific origins.
+
+# Docker connection failed
+WARNING: Docker not available. Agent deployment disabled.
+```
+
+## 🚀 Best Practices
+
+### Production Deployment
+
+1. **Use Docker secrets** for all sensitive data
+2. **Set specific CORS origins** (never use wildcards)
+3. **Enable rate limiting** and input validation
+4. **Configure appropriate timeouts** for your network
+5. **Enable observability** (tracing, metrics, logs)
+6. **Use conservative feature flags** until tested
+
+### Security Hardening
+
+1. **Rotate secrets regularly** using automated processes
+2. **Use TLS everywhere** in production
+3. **Monitor security logs** for suspicious activity  
+4. **Keep dependency versions updated**
+5. **Review access logs** regularly
+
+### Performance Optimization
+
+1. **Tune database connection pools** based on load
+2. **Configure appropriate cache settings**
+3. **Use CDN for static assets** if applicable
+4. **Monitor resource usage** and scale accordingly
+5. **Enable compression** for large responses
+
+### Troubleshooting
+
+1. **Enable debug logging** temporarily for issues
+2. **Check health endpoints** for component status
+3. **Monitor trace data** for request flow issues
+4. **Validate configuration** before deployment
+5. **Test in staging environment** first

+# WHOOSH Production Deployment Guide
+
+This guide provides comprehensive instructions for deploying WHOOSH Council Formation Engine in production environments using Docker Swarm orchestration.
+
+## 📋 Prerequisites
+
+### Infrastructure Requirements
+
+**Docker Swarm Cluster**
+- Docker Engine 20.10+ on all nodes
+- Docker Swarm mode initialized
+- Minimum 3 nodes for high availability (1 manager, 2+ workers)
+- Shared storage for persistent volumes (NFS recommended)
+
+**Network Configuration**
+- Overlay networks for service communication
+- External network access for Gitea integration
+- SSL/TLS certificates for HTTPS endpoints
+- DNS configuration for service discovery
+
+**Resource Requirements**
+```yaml
+WHOOSH Service (per replica):
+  Memory: 256MB limit, 128MB reservation
+  CPU: 0.5 cores limit, 0.25 cores reservation
+
+PostgreSQL Database:
+  Memory: 512MB limit, 256MB reservation  
+  CPU: 1.0 cores limit, 0.5 cores reservation
+  Storage: 10GB+ persistent volume
+```
+
+### External Dependencies
+
+**Required Services**
+- **Gitea Instance**: Repository hosting and webhook integration
+- **Traefik**: Reverse proxy with SSL termination
+- **BackBeat**: Performance monitoring (optional but recommended)
+- **NATS**: Message bus for BackBeat integration
+
+**Network Connectivity**
+- WHOOSH → Gitea (API access and webhook delivery)
+- WHOOSH → PostgreSQL (database connections)
+- WHOOSH → Docker Socket (agent deployment)
+- External → WHOOSH (webhook delivery and API access)
+
+## 🔐 Security Setup
+
+### Docker Secrets Management
+
+Create all required secrets before deployment:
+
+```bash
+# Database password
+echo "your-secure-db-password" | docker secret create whoosh_db_password -
+
+# Gitea API token (from Gitea settings)
+echo "your-gitea-api-token" | docker secret create gitea_token -
+
+# Webhook secret (same as configured in Gitea webhook)
+echo "your-webhook-secret" | docker secret create whoosh_webhook_token -
+
+# JWT secret (minimum 32 characters)
+echo "your-strong-jwt-secret-minimum-32-chars" | docker secret create whoosh_jwt_secret -
+
+# Service tokens (comma-separated)
+echo "internal-service-token1,api-automation-token2" | docker secret create whoosh_service_tokens -
+```
+
+### Secret Validation

-# WHOOSH Transformation Development Plan
-## Autonomous AI Development Teams Architecture
+# WHOOSH Development Plan - Production Ready Council Formation Engine
 
-Sanity Addendum (Go + MVP-first)
-- Backend in Go for consistency with CHORUS; HTTP/WS with chi/echo, JSON Schema validation, structured logs. Optional Team Composer as a separate Go service calling local Ollama endpoints (cloud models opt-in only).
-- Orchestration: Docker Swarm with nginx ingress; secrets via Swarm; SHHH scrubbing at API/WS ingress and before logging.
-- MVP-first scope: single-agent path acting on `bzzz-task` issues → PRs; WHOOSH provides minimal API + status views. Defer HMMM channels/consensus and full Composer until post-MVP.
-- Database: start with a minimal subset (teams, team_roles, team_assignments, agents-min, slurp_submissions-min). Defer broad ENUMs/materialized views and analytics until stable.
-- Determinism & safety: Validate all LLM outputs (when enabled) against versioned JSON Schemas; cache analyses with TTL; rate limit; apply path allowlists and diff caps; redact secrets.

+# WHOOSH Roadmap
+
+_Last updated: 2025-02-15_
+
+This roadmap breaks the WHOOSH council formation platform into phased milestones, sequencing the work needed to evolve from the current council-focused release to fully autonomous team orchestration with reliable telemetry and UI coverage.
+
+## Phase 0 – Alignment & Readiness (Week 0)
+- Confirm owners for API/persistence, analysis ingestion, deployment orchestrator, and UI work streams.
+- Audit existing deployments (Docker Swarm + Postgres) for parity with production configs.
+- Capture outstanding tech debt from `DEVELOPMENT_PLAN.md` into tracking tooling with the milestone tags below.
+
+**Exit criteria**
+- Ownership assigned with sprint plans.
+- Backlog groomed with roadmap milestone labels (`WSH-API`, `WSH-ANALYSIS`, `WSH-OBS`, `WSH-AUTO`, `WSH-UX`).
+
+## Phase 1 – Hardening the Data Path (Weeks 1–4)
+- **WSH-API (Weeks 1–2)**
+  - Replace mock project/council handlers with Postgres read/write paths.
+  - Add migrations + integration tests for repository, issue, council, and artifact tables.
+- **WSH-ANALYSIS (Weeks 2–4)**
+  - Pipe Gitea/n8n analysis results into composer inputs (tech stack, requirements, risk flags).
+  - Persist analysis snapshots and expose via API.
+
+**Exit criteria**
+- WHOOSH API/UI operates solely on persisted data; no mock payloads in server handlers.
+- New/Analyze flows populate composer with real issue metadata.
+
+## Phase 2 – Deployment Telemetry & Observability (Weeks 4–7)
+- **WSH-OBS (Weeks 4–6)**
+  - Record deployment results in database and surface status in API/UI.
+  - Instrument Swarm deployment with structured logs + Prometheus metrics (success/failure, duration).
+- **WSH-TELEM (Weeks 5–7)**
+  - Emit telemetry events for KACHING (council/job counts, agent minutes, failure alerts).
+  - Build Grafana/Metabase dashboards for council throughput and deployment health.
+
+**Exit criteria**
+- Deployment outcomes visible in UI and exportable via API.
+- Telemetry feeds KACHING pipeline with validated sample data; dashboards in place.
+
+## Phase 3 – Autonomous Team Evolution (Weeks 7–10)
+- **WSH-AUTO (Weeks 7–9)**
+  - Turn composer outputs into actionable team formation + self-joining flows.
+  - Enforce role availability caps, load balancing, and join/leave workflows.
+- **WSH-COLLAB (Weeks 8–10)**
+  - Integrate HMMM rooms & capability announcements for formed teams.
+  - Add escalation + review loops via SLURP/BUBBLE decision hooks.
+
+**Exit criteria**
+- Councils hand off to autonomous teams with recorded assignments.
+- Team state synced to SLURP/BUBBLE/HMMM; QA sign-off on end-to-end kickoff-to-deliverable scenario.
+
+## Phase 4 – UX & Governance (Weeks 10–12)
+- **WSH-UX (Weeks 10–11)**
+  - Polish admin dashboard: council progress, telemetry widgets, failure triage.
+  - Document operator runbooks in `docs/admin-guide`.
+- **WSH-GOV (Weeks 11–12)**
+  - Generate Decision Records for major orchestration flows (UCXL addresses linked).
+  - Finalize compliance hooks (SHHH redaction, audit exports).
+
+**Exit criteria**
+- Admin/operator journeys validated; documentation complete.
+- Decision Records published; compliance/audit requirements satisfied.
+
+## Tracking & Reporting
+- Weekly sync across work streams with burndown, blocker, and risk review.
+- Metrics to monitor: council formation latency, deployment success %, telemetry delivery rate, autonomous team adoption.
+- All major architecture/security decisions recorded in SLURP/BUBBLE at the relevant UCXL addresses.

+# WHOOSH speclint helper
+
+Runs a local, self‑contained traceability check that enforces Suite 2.0.0 rules without relying on a monorepo path.
+
+Usage:
+
+```
+python3 scripts/speclint_check.py check . --require-ucxl --max-distance 5
+```
+
+Exit codes:
+- 0: no issues
+- 1: validation errors
+- 2: internal error
+
+This mirrors the suite speclint behavior and can run standalone in WHOOSH CI.

+# go-winio [![Build Status](https://github.com/microsoft/go-winio/actions/workflows/ci.yml/badge.svg)](https://github.com/microsoft/go-winio/actions/workflows/ci.yml)
+
+This repository contains utilities for efficiently performing Win32 IO operations in
+Go. Currently, this is focused on accessing named pipes and other file handles, and
+for using named pipes as a net transport.
+
+This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
+to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
+newer operating systems. This is similar to the implementation of network sockets in Go's net
+package.
+
+Please see the LICENSE file for licensing information.
+
+## Contributing
+
+This project welcomes contributions and suggestions.
+Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
+you have the right to, and actually do, grant us the rights to use your contribution.
+For details, visit [Microsoft CLA](https://cla.microsoft.com).
+
+When you submit a pull request, a CLA-bot will automatically determine whether you need to
+provide a CLA and decorate the PR appropriately (e.g., label, comment).
+Simply follow the instructions provided by the bot.
+You will only need to do this once across all repos using our CLA.
+
+Additionally, the pull request pipeline requires the following steps to be performed before
+mergining.
+
+### Code Sign-Off
+
+We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+
+A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
+
+Please see [the developer certificate](https://developercertificate.org) for more info,
+as well as to make sure that you can attest to the rules listed.
+Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+    "go.lintTool": "golangci-lint",
+    "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run ./...
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+
+This can be done for the entire repo:
+
+```shell
+> go generate ./...
+```

+A Form Encoding & Decoding Package for Go, written by [Alvaro J. Genial](http://alva.ro).
+
+[![Build Status](https://travis-ci.org/ajg/form.png?branch=master)](https://travis-ci.org/ajg/form)
+[![GoDoc](https://godoc.org/github.com/ajg/form?status.png)](https://godoc.org/github.com/ajg/form)
+
+Synopsis
+--------
+
+This library is designed to allow seamless, high-fidelity encoding and decoding of arbitrary data in `application/x-www-form-urlencoded` format and as [`url.Values`](http://golang.org/pkg/net/url/#Values). It is intended to be useful primarily in dealing with web forms and URI query strings, both of which natively employ said format.
+
+Unsurprisingly, `form` is modeled after other Go [`encoding`](http://golang.org/pkg/encoding/) packages, in particular [`encoding/json`](http://golang.org/pkg/encoding/json/), and follows the same conventions (see below for more.) It aims to automatically handle any kind of concrete Go [data value](#values) (i.e., not functions, channels, etc.) while providing mechanisms for custom behavior.
+
+Status
+------
+
+The implementation is in usable shape and is fairly well tested with its accompanying test suite. The API is unlikely to change much, but still may. Lastly, the code has not yet undergone a security review to ensure it is free of vulnerabilities. Please file an issue or send a pull request for fixes & improvements.
+
+Dependencies
+------------
+
+The only requirement is [Go 1.2](http://golang.org/doc/go1.2) or later.
+
+Usage
+-----
+
+```go
+import "github.com/ajg/form"
+// or: "gopkg.in/ajg/form.v1"
+```
+
+Given a type like the following...
+
+```go
+type User struct {
+	Name         string            `form:"name"`
+	Email        string            `form:"email"`
+	Joined       time.Time         `form:"joined,omitempty"`
+	Posts        []int             `form:"posts"`
+	Preferences  map[string]string `form:"prefs"`
+	Avatar       []byte            `form:"avatar"`
+	PasswordHash int64             `form:"-"`
+}
+```
+
+...it is easy to encode data of that type...
+
+
+```go
+func PostUser(url string, u User) error {
+	var c http.Client
+	_, err := c.PostForm(url, form.EncodeToValues(u))
+	return err
+}
+```
+
+...as well as decode it...
+
+
+```go
+func Handler(w http.ResponseWriter, r *http.Request) {
+	var u User
+
+	d := form.NewDecoder(r.Body)
+	if err := d.Decode(&u); err != nil {
+		http.Error(w, "Form could not be decoded", http.StatusBadRequest)
+		return
+	}
+
+	fmt.Fprintf(w, "Decoded: %#v", u)
+}
+```
+
+...without having to do any grunt work.
+
+Field Tags
+----------
+
+Like other encoding packages, `form` supports the following options for fields:
+
+ - `` `form:"-"` ``: Causes the field to be ignored during encoding and decoding.
+ - `` `form:"<name>"` ``: Overrides the field's name; useful especially when dealing with external identifiers in camelCase, as are commonly found on the web.
+ - `` `form:",omitempty"` ``: Elides the field during encoding if it is empty (typically meaning equal to the type's zero value.)
+ - `` `form:"<name>,omitempty"` ``: The way to combine the two options above.
+
+Values
+------
+
+### Simple Values
+
+Values of the following types are all considered simple:
+
+ - `bool`
+ - `int`, `int8`, `int16`, `int32`, `int64`, `rune`
+ - `uint`, `uint8`, `uint16`, `uint32`, `uint64`, `byte`
+ - `float32`, `float64`
+ - `complex64`, `complex128`
+ - `string`
+ - `[]byte` (see note)
+ - [`time.Time`](http://golang.org/pkg/time/#Time)
+ - [`url.URL`](http://golang.org/pkg/net/url/#URL)
+ - An alias of any of the above
+ - A pointer to any of the above
+
+### Composite Values
+
+A composite value is one that can contain other values. Values of the following kinds...
+
+ - Maps
+ - Slices; except `[]byte` (see note)
+ - Structs; except [`time.Time`](http://golang.org/pkg/time/#Time) and [`url.URL`](http://golang.org/pkg/net/url/#URL)
+ - Arrays
+ - An alias of any of the above
+ - A pointer to any of the above
+
+...are considered composites in general, unless they implement custom marshaling/unmarshaling. Composite values are encoded as a flat mapping of paths to values, where the paths are constructed by joining the parent and child paths with a period (`.`).
+
+(Note: a byte slice is treated as a `string` by default because it's more efficient, but can also be decoded as a slice—i.e., with indexes.)
+
+### Untyped Values
+
+While encouraged, it is not necessary to define a type (e.g. a `struct`) in order to use `form`, since it is able to encode and decode untyped data generically using the following rules:
+
+ - Simple values will be treated as a `string`.
+ - Composite values will be treated as a `map[string]interface{}`, itself able to contain nested values (both scalar and compound) ad infinitum.
+ - However, if there is a value (of any supported type) already present in a map for a given key, then it will be used when possible, rather than being replaced with a generic value as specified above; this makes it possible to handle partially typed, dynamic or schema-less values.
+
+### Zero Values
+
+By default, and without custom marshaling, zero values (also known as empty/default values) are encoded as the empty string. To disable this behavior, meaning to keep zero values in their literal form (e.g. `0` for integral types), `Encoder` offers a `KeepZeros` setter method, which will do just that when set to `true`.
+
+### Unsupported Values
+
+Values of the following kinds aren't supported and, if present, must be ignored.
+
+ - Channel
+ - Function
+ - Unsafe pointer
+ - An alias of any of the above
+ - A pointer to any of the above
+
+Custom Marshaling
+-----------------
+
+There is a default (generally lossless) marshaling & unmarshaling scheme for any concrete data value in Go, which is good enough in most cases. However, it is possible to override it and use a custom scheme. For instance, a "binary" field could be marshaled more efficiently using [base64](http://golang.org/pkg/encoding/base64/) to prevent it from being percent-escaped during serialization to `application/x-www-form-urlencoded` format.
+
+Because `form` provides support for [`encoding.TextMarshaler`](http://golang.org/pkg/encoding/#TextMarshaler) and [`encoding.TextUnmarshaler`](http://golang.org/pkg/encoding/#TextUnmarshaler) it is easy to do that; for instance, like this:
+
+```go
+import "encoding"
+
+type Binary []byte
+
+var (
+	_ encoding.TextMarshaler   = &Binary{}
+	_ encoding.TextUnmarshaler = &Binary{}
+)
+
+func (b Binary) MarshalText() ([]byte, error) {
+	return []byte(base64.URLEncoding.EncodeToString([]byte(b))), nil
+}
+
+func (b *Binary) UnmarshalText(text []byte) error {
+	bs, err := base64.URLEncoding.DecodeString(string(text))
+	if err == nil {
+		*b = Binary(bs)
+	}
+	return err
+}
+```
+
+Now any value with type `Binary` will automatically be encoded using the [URL](http://golang.org/pkg/encoding/base64/#URLEncoding) variant of base64. It is left as an exercise to the reader to improve upon this scheme by eliminating the need for padding (which, besides being superfluous, uses `=`, a character that will end up percent-escaped.)
+
+Keys
+----
+
+In theory any value can be a key as long as it has a string representation. However, by default, periods have special meaning to `form`, and thus, under the hood (i.e. in encoded form) they are transparently escaped using a preceding backslash (`\`). Backslashes within keys, themselves, are also escaped in this manner (e.g. as `\\`) in order to permit representing `\.` itself (as `\\\.`).
+
+(Note: it is normally unnecessary to deal with this issue unless keys are being constructed manually—e.g. literally embedded in HTML or in a URI.)
+
+The default delimiter and escape characters used for encoding and decoding composite keys can be changed using the `DelimitWith` and `EscapeWith` setter methods of `Encoder` and `Decoder`, respectively. For example...
+
+```go
+package main
+
+import (
+	"os"
+
+	"github.com/ajg/form"
+)
+
+func main() {
+	type B struct {
+		Qux string `form:"qux"`
+	}
+	type A struct {
+		FooBar B `form:"foo.bar"`
+	}
+	a := A{FooBar: B{"XYZ"}}
+	os.Stdout.WriteString("Default: ")
+	form.NewEncoder(os.Stdout).Encode(a)
+	os.Stdout.WriteString("\nCustom:  ")
+	form.NewEncoder(os.Stdout).DelimitWith('/').Encode(a)
+	os.Stdout.WriteString("\n")
+}
+
+```
+
+...will produce...
+
+```
+Default: foo%5C.bar.qux=XYZ
+Custom:  foo.bar%2Fqux=XYZ
+```
+
+(`%5C` and `%2F` represent `\` and `/`, respectively.)
+
+Limitations
+-----------
+
+ - Circular (self-referential) values are untested.
+
+Future Work
+-----------
+
+The following items would be nice to have in the future—though they are not being worked on yet:
+
+ - An option to treat all values as if they had been tagged with `omitempty`.
+ - An option to automatically treat all field names in `camelCase` or `underscore_case`.
+ - Built-in support for the types in [`math/big`](http://golang.org/pkg/math/big/).
+ - Built-in support for the types in [`image/color`](http://golang.org/pkg/image/color/).
+ - Improve encoding/decoding by reading/writing directly from/to the `io.Reader`/`io.Writer` when possible, rather than going through an intermediate representation (i.e. `node`) which requires more memory.
+
+(Feel free to implement any of these and then send a pull request.)
+
+Related Work
+------------
+
+ - Package [gorilla/schema](https://github.com/gorilla/schema), which only implements decoding.
+ - Package [google/go-querystring](https://github.com/google/go-querystring), which only implements encoding.

+# BACKBEAT Go SDK
+
+The BACKBEAT Go SDK enables CHORUS services to become "BACKBEAT-aware" by providing client libraries for beat synchronization, status emission, and beat-budget management.
+
+## Features
+
+- **Beat Subscription (BACKBEAT-REQ-040)**: Subscribe to beat and downbeat events with jitter-tolerant scheduling
+- **Status Emission (BACKBEAT-REQ-041)**: Emit status claims with automatic agent_id, task_id, and HLC population
+- **Beat Budgets (BACKBEAT-REQ-042)**: Execute functions with beat-based timeouts and cancellation
+- **Legacy Compatibility (BACKBEAT-REQ-043)**: Support for legacy `{bar,beat}` patterns with migration warnings
+- **Security (BACKBEAT-REQ-044)**: Ed25519 signing and required headers for status claims
+- **Local Degradation**: Continue operating when pulse service is unavailable
+- **Comprehensive Observability**: Metrics, health reporting, and performance monitoring
+
+## Quick Start
+
+```go
+package main
+
+import (
+    "context"
+    "crypto/ed25519"
+    "crypto/rand"
+    "log/slog"
+    
+    "github.com/chorus-services/backbeat/pkg/sdk"
+)
+
+func main() {
+    // Generate signing key
+    _, signingKey, _ := ed25519.GenerateKey(rand.Reader)
+    
+    // Configure SDK
+    config := sdk.DefaultConfig()
+    config.ClusterID = "chorus-dev"
+    config.AgentID = "my-service"
+    config.NATSUrl = "nats://localhost:4222"
+    config.SigningKey = signingKey
+    
+    // Create client
+    client := sdk.NewClient(config)
+    
+    // Register beat callback
+    client.OnBeat(func(beat sdk.BeatFrame) {
+        slog.Info("Beat received", "beat_index", beat.BeatIndex)
+        
+        // Emit status
+        client.EmitStatusClaim(sdk.StatusClaim{
+            State:     "executing",
+            BeatsLeft: 5,
+            Progress:  0.3,
+            Notes:     "Processing data",
+        })
+    })
+    
+    // Start client
+    ctx := context.Background()
+    if err := client.Start(ctx); err != nil {
+        panic(err)
+    }
+    defer client.Stop()
+    
+    // Your service logic here...
+    select {}
+}
+```
+
+## Configuration
+
+### Basic Configuration
+
+```go
+config := &sdk.Config{
+    ClusterID: "your-cluster",    // BACKBEAT cluster ID
+    AgentID:   "your-agent",      // Unique agent identifier
+    NATSUrl:   "nats://localhost:4222", // NATS connection URL
+}
+```
+
+### Advanced Configuration
+
+```go
+config := sdk.DefaultConfig()
+config.ClusterID = "chorus-prod"
+config.AgentID = "web-service-01"
+config.NATSUrl = "nats://nats.cluster.local:4222"
+config.SigningKey = loadSigningKey() // Ed25519 private key
+config.JitterTolerance = 100 * time.Millisecond
+config.ReconnectDelay = 2 * time.Second
+config.MaxReconnects = 10 // -1 for infinite
+config.Logger = slog.New(slog.NewJSONHandler(os.Stdout, nil))
+```
+
+## Core Features
+
+### Beat Subscription
+
+```go
+// Register beat callback (called every beat)
+client.OnBeat(func(beat sdk.BeatFrame) {
+    // Your beat logic here
+    fmt.Printf("Beat %d at %s\n", beat.BeatIndex, beat.DeadlineAt)
+})
+
+// Register downbeat callback (called at bar starts)
+client.OnDownbeat(func(beat sdk.BeatFrame) {
+    // Your downbeat logic here
+    fmt.Printf("Bar started: %s\n", beat.WindowID)
+})
+```
+
+### Status Emission
+
+```go
+// Basic status emission
+err := client.EmitStatusClaim(sdk.StatusClaim{
+    State:     "executing",  // executing|planning|waiting|review|done|failed
+    BeatsLeft: 10,          // estimated beats remaining
+    Progress:  0.75,        // progress ratio (0.0-1.0)
+    Notes:     "Processing batch 5/10",
+})
+
+// Advanced status with task tracking
+err := client.EmitStatusClaim(sdk.StatusClaim{
+    TaskID:    "task-12345", // auto-generated if empty
+    State:     "waiting",
+    WaitFor:   []string{"hmmm://thread/abc123"}, // dependencies
+    BeatsLeft: 0,
+    Progress:  1.0,
+    Notes:     "Waiting for thread completion",
+})
+```
+
+### Beat Budgets
+
+```go
+// Execute with beat-based timeout
+err := client.WithBeatBudget(10, func() error {
+    // This function has 10 beats to complete
+    return performTask()
+})
+
+if err != nil {
+    // Handle timeout or task error
+    fmt.Printf("Task failed or exceeded budget: %v\n", err)
+}
+
+// Real-world example
+err := client.WithBeatBudget(20, func() error {
+    // Database operation with beat budget
+    ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+    defer cancel()
+    
+    return database.ProcessBatch(ctx, batchData)
+})
+```
+
+## Client Interface
+
+```go
+type Client interface {
+    // Beat subscription
+    OnBeat(callback func(BeatFrame)) error
+    OnDownbeat(callback func(BeatFrame)) error
+    
+    // Status emission
+    EmitStatusClaim(claim StatusClaim) error
+    
+    // Beat budgets
+    WithBeatBudget(n int, fn func() error) error
+    
+    // Utilities
+    GetCurrentBeat() int64
+    GetCurrentWindow() string
+    IsInWindow(windowID string) bool
+    
+    // Lifecycle
+    Start(ctx context.Context) error
+    Stop() error
+    Health() HealthStatus
+}
+```
+
+## Examples
+
+The SDK includes comprehensive examples:
+
+- **[Simple Agent](examples/simple_agent.go)**: Basic beat subscription and status emission
+- **[Task Processor](examples/task_processor.go)**: Beat budget usage for task timeout management
+- **[Service Monitor](examples/service_monitor.go)**: Health monitoring with beat-aligned reporting
+
+### Running Examples
+
+```bash
+# Simple agent example
+go run pkg/sdk/examples/simple_agent.go
+
+# Task processor with beat budgets
+go run pkg/sdk/examples/task_processor.go
+
+# Service monitor with health reporting
+go run pkg/sdk/examples/service_monitor.go
+```
+
+## Observability
+
+### Health Monitoring
+
+```go
+health := client.Health()
+fmt.Printf("Connected: %v\n", health.Connected)
+fmt.Printf("Last Beat: %d at %s\n", health.LastBeat, health.LastBeatTime)
+fmt.Printf("Time Drift: %s\n", health.TimeDrift)
+fmt.Printf("Reconnects: %d\n", health.ReconnectCount)
+fmt.Printf("Local Degradation: %v\n", health.LocalDegradation)
+```
+
+### Metrics
+
+The SDK exposes metrics via Go's `expvar` package:
+
+- Connection metrics: status, reconnection count, duration
+- Beat metrics: received, jitter, callback latency, misses
+- Status metrics: claims emitted, errors
+- Budget metrics: created, completed, timed out
+- Error metrics: total count, last error
+
+Access metrics at `http://localhost:8080/debug/vars` when using `expvar`.
+
+### Logging
+
+The SDK uses structured logging via `slog`:
+
+```go
+config.Logger = slog.New(slog.NewJSONHandler(os.Stdout, &slog.HandlerOptions{
+    Level: slog.LevelDebug, // Set appropriate level
+}))
+```
+
+## Error Handling
+
+The SDK provides comprehensive error handling:
+
+- **Connection Errors**: Automatic reconnection with exponential backoff
+- **Beat Jitter**: Tolerance for network delays and timing variations  
+- **Callback Panics**: Recovery and logging without affecting other callbacks
+- **Validation Errors**: Status claim validation with detailed error messages
+- **Timeout Errors**: Beat budget timeouts with context cancellation
+
+## Local Degradation
+
+When the pulse service is unavailable, the SDK automatically enters local degradation mode:
+
+- Generates synthetic beats to maintain callback timing
+- Uses fallback 60 BPM tempo
+- Marks beat frames with "degraded" phase
+- Automatically recovers when pulse service returns
+
+## Legacy Compatibility
+
+Support for legacy `{bar,beat}` patterns (BACKBEAT-REQ-043):
+
+```go
+// Convert legacy format (logs warning once)
+beatIndex := client.ConvertLegacyBeat(bar, beat)
+
+// Get legacy format from current beat
+legacy := client.GetLegacyBeatInfo()
+fmt.Printf("Bar: %d, Beat: %d\n", legacy.Bar, legacy.Beat)
+```
+
+## Security
+
+The SDK implements BACKBEAT security requirements:
+
+- **Ed25519 Signatures**: All status claims are signed when signing key provided
+- **Required Headers**: Includes `x-window-id` and `x-hlc` headers
+- **Agent Identification**: Automatic `x-agent-id` header for routing
+
+```go
+// Configure signing
+_, signingKey, _ := ed25519.GenerateKey(rand.Reader)
+config.SigningKey = signingKey
+```
+
+## Performance
+
+The SDK is designed for high performance:
+
+- **Beat Callback Latency**: Target ≤5ms callback execution
+- **Timer Drift**: ≤1% drift over 1 hour without leader
+- **Concurrent Safe**: All operations are goroutine-safe
+- **Memory Efficient**: Bounded error lists and metric samples
+
+## Integration Patterns
+
+### Web Service Integration
+
+```go
+func main() {
+    // Initialize BACKBEAT client
+    client := sdk.NewClient(config)
+    client.OnBeat(func(beat sdk.BeatFrame) {
+        // Report web service status
+        client.EmitStatusClaim(sdk.StatusClaim{
+            State: "executing",
+            Progress: getRequestSuccessRate(),
+            Notes: fmt.Sprintf("Handling %d req/s", getCurrentRPS()),
+        })
+    })
+    
+    // Start HTTP server
+    http.HandleFunc("/health", func(w http.ResponseWriter, r *http.Request) {
+        health := client.Health()
+        json.NewEncoder(w).Encode(health)
+    })
+}
+```
+
+### Background Job Processor
+
+```go
+func processJobs(client sdk.Client) {
+    for job := range jobQueue {
+        // Use beat budget for job timeout
+        err := client.WithBeatBudget(job.MaxBeats, func() error {
+            return processJob(job)
+        })
+        
+        if err != nil {
+            client.EmitStatusClaim(sdk.StatusClaim{
+                TaskID: job.ID,
+                State: "failed", 
+                Notes: err.Error(),
+            })
+        }
+    }
+}
+```
+
+## Testing
+
+The SDK includes comprehensive test utilities:
+
+```bash
+# Run all tests
+go test ./pkg/sdk/...
+
+# Run with race detection
+go test -race ./pkg/sdk/...
+
+# Run benchmarks
+go test -bench=. ./pkg/sdk/examples/
+```
+
+## Requirements
+

+//   - Emit status claims with automatic metadata population
+//   - Use beat budgets for timeout management
+//   - Operate in local degradation mode when pulse unavailable
+//   - Integrate comprehensive observability and health reporting

+//	fmt.Printf("Reconnects: %d\n", health.ReconnectCount)
+//
+// # Local Degradation
+//
+// The SDK automatically handles network issues by entering local degradation mode:
+//   - Generates synthetic beats when pulse service unavailable
+//   - Uses fallback timing to maintain callback schedules  
+//   - Automatically recovers when pulse service returns
+//   - Provides seamless operation during network partitions
+//
+// # Security
+//
+// The SDK implements BACKBEAT security requirements:
+//   - Ed25519 signing of all status claims when key provided
+//   - Required x-window-id and x-hlc headers
+//   - Agent identification for proper message routing
+//
+// # Performance
+//
+// Designed for production use with:
+//   - Beat callback latency target ≤5ms
+//   - Timer drift ≤1% over 1 hour without leader
+//   - Goroutine-safe concurrent operations
+//   - Bounded memory usage for metrics and errors
+//
+// # Examples
+//
+// See the examples subdirectory for complete usage patterns:
+//   - examples/simple_agent.go: Basic integration
+//   - examples/task_processor.go: Beat budget usage
+//   - examples/service_monitor.go: Health monitoring

+# Working on the Engine API
+
+The Engine API is an HTTP API used by the command-line client to communicate with the daemon. It can also be used by third-party software to control the daemon.
+
+It consists of various components in this repository:
+
+- `api/swagger.yaml` A Swagger definition of the API.
+- `api/types/` Types shared by both the client and server, representing various objects, options, responses, etc. Most are written manually, but some are automatically generated from the Swagger definition. See [#27919](https://github.com/docker/docker/issues/27919) for progress on this.
+- `cli/` The command-line client.
+- `client/` The Go client used by the command-line client. It can also be used by third-party Go programs.
+- `daemon/` The daemon, which serves the API.
+
+## Swagger definition
+
+The API is defined by the [Swagger](http://swagger.io/specification/) definition in `api/swagger.yaml`. This definition can be used to:
+
+1. Automatically generate documentation.
+2. Automatically generate the Go server and client. (A work-in-progress.)
+3. Provide a machine readable version of the API for introspecting what it can do, automatically generating clients for other languages, etc.
+
+## Updating the API documentation
+
+The API documentation is generated entirely from `api/swagger.yaml`. If you make updates to the API, edit this file to represent the change in the documentation.
+
+The file is split into two main sections:
+
+- `definitions`, which defines re-usable objects used in requests and responses
+- `paths`, which defines the API endpoints (and some inline objects which don't need to be reusable)
+
+To make an edit, first look for the endpoint you want to edit under `paths`, then make the required edits. Endpoints may reference reusable objects with `$ref`, which can be found in the `definitions` section.
+
+There is hopefully enough example material in the file for you to copy a similar pattern from elsewhere in the file (e.g. adding new fields or endpoints), but for the full reference, see the [Swagger specification](https://github.com/docker/docker/issues/27919).
+
+`swagger.yaml` is validated by `hack/validate/swagger` to ensure it is a valid Swagger definition. This is useful when making edits to ensure you are doing the right thing.
+
+## Viewing the API documentation
+
+When you make edits to `swagger.yaml`, you may want to check the generated API documentation to ensure it renders correctly.
+
+Run `make swagger-docs` and a preview will be running at `http://localhost`. Some of the styling may be incorrect, but you'll be able to ensure that it is generating the correct documentation.
+
+The production documentation is generated by vendoring `swagger.yaml` into [docker/docker.github.io](https://github.com/docker/docker.github.io).
