Summary

P2P Connectivity Restored: Fixed regression that broke P2P mesh networking in Task Execution Engine implementation
Dynamic Versioning: Replaced hardcoded "0.1.0-dev" with build-time injection showing commit hash and build date
Container Compatibility: Added Ubuntu-based Dockerfile for reliable glibc execution across Docker Swarm nodes

Root Cause Analysis

The P2P connectivity regression was caused by mDNS discovery being conditionally disabled during Task Execution Engine implementation. The working baseline (eb2e05f) always enabled mDNS discovery, but the new code made it conditional on cfg.V2.DHT.MDNSEnabled.

Key Technical Fixes

P2P Connectivity

  • File: internal/runtime/shared.go:251-256
  • Change: Removed conditional check, always enable mDNS discovery like baseline
  • Impact: Docker Swarm containers can now discover each other via mDNS

Dynamic Versioning

  • Files: cmd/agent/main.go, internal/runtime/shared.go, Makefile
  • Change: Implemented ldflags injection: -X main.version=$(VERSION)
  • Result: CHORUS-agent 0.5.5 (build: 9dbd361, 2025-09-26_05:55:55)

Container Base Image

  • File: Dockerfile.ubuntu (new)
  • Change: Ubuntu 22.04 base instead of Alpine for glibc compatibility
  • Benefit: Eliminates binary execution failures in containers

Verification Results

🎯 Deployed to Production: 9/9 Docker Swarm replicas running successfully

📊 P2P Metrics:

  • Peer discovery and mesh connectivity
  • Democratic leader election (<peer.ID 12*5hsnq6> elected)
  • BACKBEAT beat synchronization
  • Availability broadcasts between peers
  • Health checks passing (pubsub-enhanced, p2p-connectivity, task-manager)

📝 Logs Showing Success:

🐝 Bzzz [availability_broadcast] from <peer.ID 12*pirCrC>
📡 Admin confirmed: <peer.ID 12*5hsnq6> (reported by multiple peers)
[INFO] Health check passed: p2p-connectivity (latency: 13.2µs)
🎭 Starting CHORUS v0.5.5 (build: 9dbd361, 2025-09-26_05:55:55)

Task Execution Engine Preservation

All Phase 4 functionality preserved:

  • AI provider integration (ResetData, Ollama, OpenAI)
  • Docker sandbox execution environments
  • Task engine with priority scoring
  • Repository providers (GitHub, GitLab, Gitea)

Deployment Strategy

  • Image: anthonyrawlins/chorus:latest (Ubuntu-based)
  • Auto-Updates: Watchtower integration for continuous deployment
  • Backwards Compatible: All existing Task Execution Engine APIs maintained

Test Plan

  • 9/9 Docker Swarm replicas running
  • P2P mesh connectivity verified
  • Democratic leader election working
  • Dynamic version reporting functional
  • Task Execution Engine APIs operational
  • Container health checks passing
  • BACKBEAT synchronization active

This PR successfully fixes the P2P connectivity regression while preserving all Task Execution Engine functionality and implementing a robust dynamic versioning system for future debugging.

## Problem Analysis
- WHOOSH service was failing to start due to BACKBEAT NATS connectivity issues
- Containers were unable to resolve "backbeat-nats" hostname from DNS
- Service was stuck in deployment loops with all replicas failing
- Root cause: Missing WHOOSH_BACKBEAT_NATS_URL environment variable configuration

## Solution Implementation

### 1. BACKBEAT Configuration Fix
- **Added explicit WHOOSH BACKBEAT environment variables** to docker-compose.yml:
  - `WHOOSH_BACKBEAT_ENABLED: "false"` (temporarily disabled for stability)
  - `WHOOSH_BACKBEAT_CLUSTER_ID: "chorus-production"`
  - `WHOOSH_BACKBEAT_AGENT_ID: "whoosh"`
  - `WHOOSH_BACKBEAT_NATS_URL: "nats://backbeat-nats:4222"`

### 2. Service Deployment Improvements
- **Removed rosewood node constraints** across all services (gaming PC intermittency)
- **Simplified network configuration** by removing unused `whoosh-backend` network
- **Improved health check configuration** for postgres service
- **Streamlined service placement** for better distribution

### 3. Code Quality Improvements
- **Fixed code formatting** inconsistencies in HTTP server
- **Updated service comments** from "Bzzz" to "CHORUS" for clarity
- **Standardized import grouping** and spacing

## Results Achieved

###  WHOOSH Service Operational
- **Service successfully running** on walnut node (1/2 replicas healthy)
- **Health checks passing** - API accessible on port 8800
- **Database connectivity restored** - migrations completed successfully
- **Council formation working** - teams being created and tasks assigned

###  Core Functionality Verified
- **Agent discovery active** - CHORUS agents being detected and registered
- **Task processing operational** - autonomous team formation working
- **API endpoints responsive** - `/health` returning proper status
- **Service integration** - discovery of multiple CHORUS agent endpoints

## Technical Details

### Service Configuration

Current state: All 9 CHORUS containers show "📊 Status: 0 connected peers"
and " No winner found in election". P2P connectivity completely broken.

Issues:
- libp2p AutoRelay was attempted to be fixed but connectivity still failing
- Elections cannot receive candidacy or votes due to isolation
- Task Execution Engine (v0.5.0) implementation completed but P2P regressed

Status: Need to compare with pre-Task-Engine baseline to identify root cause
Next: Checkout working version before d1252ad to find what broke connectivity

ISSUE RESOLVED: All 9 CHORUS containers were showing "0 connected peers"
and elections were completely broken with " No winner found in election"

ROOT CAUSE: During Task Execution Engine implementation, ConnectionManager
and AutoRelay configuration was added to p2p/node.go, which broke P2P
connectivity in Docker Swarm overlay networks.

SOLUTION: Reverted to simple libp2p configuration from working baseline:
- Removed connmgr.NewConnManager() setup
- Removed libp2p.ConnectionManager(connManager)
- Removed libp2p.EnableAutoRelayWithStaticRelays()
- Kept only basic libp2p.EnableRelay()

VERIFICATION: All containers now show 3-4 connected peers and elections
are fully functional with candidacy announcements and voting.

PRESERVED: All Task Execution Engine functionality (v0.5.0) remains intact

## P2P Connectivity Fixes
- **Root Cause**: mDNS discovery was conditionally disabled in Task Execution Engine implementation
- **Solution**: Restored always-enabled mDNS discovery from working baseline (eb2e05f)
- **Result**: 9/9 Docker Swarm replicas with working P2P mesh, democratic elections, and leader consensus

## Dynamic Version System
- **Problem**: Hardcoded version "0.1.0-dev" in 1000+ builds made debugging impossible
- **Solution**: Implemented build-time version injection via ldflags
- **Features**: Shows commit hash, build date, and semantic version
- **Example**: `CHORUS-agent 0.5.5 (build: 9dbd361, 2025-09-26_05:55:55)`

## Container Compatibility
- **Issue**: Binary execution failed in Alpine due to glibc/musl incompatibility
- **Solution**: Added Ubuntu-based Dockerfile for proper glibc support
- **Benefit**: Reliable container execution across Docker Swarm nodes

## Key Changes
- `internal/runtime/shared.go`: Always enable mDNS discovery, dynamic version vars
- `cmd/agent/main.go`: Build-time version injection and display
- `p2p/node.go`: Restored working "🐝 Bzzz Node Status" logging format
- `Makefile`: Updated version to 0.5.5, proper ldflags configuration
- `Dockerfile.ubuntu`: New glibc-compatible container base
- `docker-compose.yml`: Updated to latest image tag for Watchtower auto-updates

## Verification
 P2P mesh connectivity: Peers exchanging availability broadcasts
 Democratic elections: Candidacy announcements and leader selection
 BACKBEAT integration: Beat synchronization and degraded mode handling
 Dynamic versioning: All containers show v0.5.5 with build metadata
 Task Execution Engine: All Phase 4 functionality preserved and working

Fixes P2P connectivity regression while preserving complete Task Execution Engine implementation.
