fix: P2P connectivity regression + dynamic versioning system

## 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.

-# CHORUS - Container-First P2P Task Coordination System
+# CHORUS – Container-First Context Platform (Alpha)
 
-CHORUS is a next-generation P2P task coordination and collaborative AI system designed from the ground up for containerized deployments. It takes the best lessons learned from CHORUS and reimagines them for Docker Swarm, Kubernetes, and modern container orchestration platforms.
+CHORUS is the runtime that ties the CHORUS ecosystem together: libp2p mesh, DHT-backed storage, council/task coordination, and (eventually) SLURP contextual intelligence. The repository you are looking at is the in-progress container-first refactor. Several core systems boot today, but higher-level services (SLURP, SHHH, full HMMM routing) are still landing.
 
-## Vision
+## Current Status
 
-CHORUS enables distributed AI agents to coordinate, collaborate, and execute tasks across container clusters, supporting deployments from single containers to hundreds of instances in enterprise environments.
+| Area | Status | Notes |
+| --- | --- | --- |
+| libp2p node + PubSub | ✅ Running | `internal/runtime/shared.go` spins up the mesh, hypercore logging, availability broadcasts. |
+| DHT + DecisionPublisher | ✅ Running | Encrypted storage wired through `pkg/dht`; decisions written via `ucxl.DecisionPublisher`. |
+| **Leader Election System** | ✅ **FULLY FUNCTIONAL** | **🎉 MILESTONE: Complete admin election with consensus, discovery protocol, heartbeats, and SLURP activation!** |
+| SLURP (context intelligence) | 🚧 Stubbed | `pkg/slurp/slurp.go` contains TODOs for resolver, temporal graphs, intelligence. Leader integration scaffolding exists but uses placeholder IDs/request forwarding. |
+| SHHH (secrets sentinel) | 🚧 Sentinel live | `pkg/shhh` redacts hypercore + PubSub payloads with audit + metrics hooks (policy replay TBD). |
+| HMMM routing | 🚧 Partial | PubSub topics join, but capability/role announcements and HMMM router wiring are placeholders (`internal/runtime/agent_support.go`). |
 
-## Key Design Principles
+See `docs/progress/CHORUS-WHOOSH-development-plan.md` for the detailed build plan and `docs/progress/CHORUS-WHOOSH-roadmap.md` for sequencing.
 
-- **Container-First**: Designed specifically for Docker/Kubernetes deployments
-- **License-Controlled**: Simple environment variable-based licensing
-- **Cloud-Native Logging**: Structured logging to stdout/stderr for container runtime collection
-- **Swarm-Ready P2P**: P2P protocols optimized for container networking
-- **Scalable Agent IDs**: Agent identification system that works across distributed deployments
-- **Zero-Config**: Minimal configuration requirements via environment variables
+## Quick Start (Alpha)
 
-## Architecture
+The container-first workflows are still evolving; expect frequent changes.
 
-CHORUS follows a microservices architecture where each container runs a single agent instance:
-
-```
-┌─────────────────┐  ┌─────────────────┐  ┌─────────────────┐
-│   CHORUS Agent  │  │   CHORUS Agent  │  │   CHORUS Agent  │
-│   Container 1   │◄─┤   Container 2   │─►│   Container N   │
-└─────────────────┘  └─────────────────┘  └─────────────────┘
-         │                      │                      │
-         └──────────────────────┼──────────────────────┘
-                                │
-                    ┌─────────────────┐
-                    │  Container      │
-                    │  Network        │
-                    │  (P2P Mesh)     │
-                    └─────────────────┘
-```
-
-## Quick Start
-
-### Prerequisites
-
-- Docker & Docker Compose
-- Valid CHORUS license key
-- Access to Ollama endpoints for AI functionality
-
-### Basic Deployment
-
-1. Clone and configure:
 ```bash
 git clone https://gitea.chorus.services/tony/CHORUS.git
 cd CHORUS
 cp docker/chorus.env.example docker/chorus.env
-# Edit docker/chorus.env with your license key and configuration
+# adjust env vars (KACHING license, bootstrap peers, etc.)
+docker compose -f docker/docker-compose.yml up --build
 ```
 
-2. Deploy:
+You’ll get a single agent container with:
+- libp2p networking (mDNS + configured bootstrap peers)
+- election heartbeat
+- DHT storage (AGE-encrypted)
+- HTTP API + health endpoints
+
+**Missing today:** SLURP context resolution, advanced SHHH policy replay, HMMM per-issue routing. Expect log warnings/TODOs for those paths.
+
+## 🎉 Leader Election System (NEW!)
+
+CHORUS now features a complete, production-ready leader election system:
+
+### Core Features
+- **Consensus-based election** with weighted scoring (uptime, capabilities, resources)
+- **Admin discovery protocol** for network-wide leader identification
+- **Heartbeat system** with automatic failover (15-second intervals)
+- **Concurrent election prevention** with randomized delays
+- **SLURP activation** on elected admin nodes
+
+### How It Works
+1. **Bootstrap**: Nodes start in idle state, no admin known
+2. **Discovery**: Nodes send discovery requests to find existing admin
+3. **Election trigger**: If no admin found after grace period, trigger election
+4. **Candidacy**: Eligible nodes announce themselves with capability scores
+5. **Consensus**: Network selects winner based on highest score
+6. **Leadership**: Winner starts heartbeats, activates SLURP functionality
+7. **Monitoring**: Nodes continuously verify admin health via heartbeats
+
+### Debugging
+Use these log patterns to monitor election health:
 ```bash
-docker-compose -f docker/docker-compose.yml up -d
+# Monitor WHOAMI messages and leader identification
+docker service logs CHORUS_chorus | grep "🤖 WHOAMI\|👑\|📡.*Discovered"
+
+# Track election cycles
+docker service logs CHORUS_chorus | grep "🗳️\|📢.*candidacy\|🏆.*winner"
+
+# Watch discovery protocol
+docker service logs CHORUS_chorus | grep "📩\|📤\|📥"
 ```
 
-3. Scale (Docker Swarm):
-```bash
-docker service scale chorus_agent=10
-```
+## Roadmap Highlights
 
-## Licensing
+1. **Security substrate** – land SHHH sentinel, finish SLURP leader-only operations, validate COOEE enrolment (see roadmap Phase 1).
+2. **Autonomous teams** – coordinate with WHOOSH for deployment telemetry + SLURP context export.
+3. **UCXL + KACHING** – hook runtime telemetry into KACHING and enforce UCXL validator.
 
-CHORUS requires a valid license key to operate. Set your license key in the environment:
+Track progress via the shared roadmap and weekly burndown dashboards.
 
-```env
-CHORUS_LICENSE_KEY=your-license-key-here
-CHORUS_LICENSE_EMAIL=your-email@example.com
-```
-
-**No license = No operation.** CHORUS will not start without valid licensing.
-
-## Differences from CHORUS
-
-| Aspect | CHORUS | CHORUS |
-|--------|------|--------|
-| Deployment | systemd service (1 per host) | Container (N per cluster) |
-| Configuration | Web UI setup | Environment variables |
-| Logging | Journal/files | stdout/stderr (structured) |
-| Licensing | Setup-time validation | Runtime environment variable |
-| Agent IDs | Host-based | Container/cluster-based |
-| P2P Discovery | mDNS local network | Container network + service discovery |
-
-## Development Status

+# Decision Record: Establish SHHH Sentinel Foundations
+
+- **Date:** 2025-02-16
+- **Status:** Accepted
+- **Context:** CHORUS roadmap Phase 1 requires a secrets sentinel (`pkg/shhh`) before we wire COOEE/WHOOSH telemetry and audit plumbing. The runtime previously emitted placeholder TODOs and logged sensitive payloads without guard rails.
+
+## Problem
+- We lacked a reusable component to detect and redact secrets prior to log/telemetry fan-out.
+- Without a dedicated sentinel we could not attach audit sinks or surface metrics for redaction events, blocking roadmap item `SEC-SHHH`.
+
+## Decision
+- Introduce `pkg/shhh` as the SHHH sentinel with:
+  - Curated default rules (API keys, bearer/OAuth tokens, private key PEM blocks, OpenAI secrets).
+  - Extensible configuration for custom regex rules and per-rule severity/tags.
+  - Optional audit sink and statistics collection for integration with COOEE/WHOOSH pipelines.
+  - Helpers to redact free-form text and `map[string]any` payloads used by our logging pipeline.
+
+## Rationale
+- Starting with a focused set of high-signal rules gives immediate coverage for the most damaging leak classes without delaying larger SLURP/SHHH workstreams.
+- The API mirrors other CHORUS subsystems (options, config structs, stats snapshots) so existing operators can plug metrics/audits without bespoke glue.
+- Providing deterministic findings/locations simplifies future enforcement (e.g., WHOOSH UI badges, COOEE replay) while keeping implementation lean.
+
+## Impact
+- Runtime components can now instantiate SHHH and guarantee `[REDACTED]` placeholders for sensitive fields.
+- Audit/event plumbing can be wired incrementally—hashes are emitted for replay without storing raw secrets.
+- Future roadmap tasks (policy driven rules, replay, UCXL evidence) can extend `pkg/shhh` rather than implementing ad-hoc redaction in each subsystem.
+
+## Related Work
+- Roadmap: `docs/progress/CHORUS-WHOOSH-roadmap.md` (Phase 1.2 `SEC-SHHH`).
+- README coverage gap noted in `README.md` table (SHHH not implemented).

+# CHORUS Task Execution Engine Development Plan
+
+## Overview
+This plan outlines the development of a comprehensive task execution engine for CHORUS agents, replacing the current mock implementation with a fully functional system that can execute real work according to agent roles and specializations.
+
+## Current State Analysis
+
+### What's Implemented ✅
+- **Task Coordinator Framework** (`coordinator/task_coordinator.go`): Full task management lifecycle with role-based assignment, collaboration requests, and HMMM integration
+- **Agent Role System**: Role announcements, capability broadcasting, and expertise matching
+- **P2P Infrastructure**: Nodes can discover each other and communicate via pubsub
+- **Health Monitoring**: Comprehensive health checks and graceful shutdown
+
+### Critical Gaps Identified ❌
+- **Task Execution Engine**: `executeTask()` only has a 10-second sleep simulation - no actual work performed
+- **Repository Integration**: Mock providers only - no real GitHub/GitLab task pulling
+- **Agent-to-Task Binding**: Task discovery relies on WHOOSH but agents don't connect to real work
+- **Role-Based Execution**: Agents announce roles but don't execute tasks according to their specialization
+- **AI Integration**: No LLM/reasoning integration for task completion
+
+## Architecture Requirements
+
+### Model and Provider Abstraction
+The execution engine must support multiple AI model providers and execution environments:
+
+**Model Provider Types:**
+- **Local Ollama**: Default for most roles (llama3.1:8b, codellama, etc.)
+- **OpenAI API**: For specialized models (chatgpt-5, gpt-4o, etc.)
+- **ResetData API**: For testing and fallback (llama3.1:8b via LaaS)
+- **Custom Endpoints**: Support for other provider APIs
+
+**Role-Model Mapping:**
+- Each role has a default model configuration
+- Specialized roles may require specific models/providers
+- Model selection transparent to execution logic
+- Support for MCP calls and tool usage regardless of provider
+
+### Execution Environment Abstraction
+Tasks must execute in secure, isolated environments while maintaining transparency:
+
+**Sandbox Types:**
+- **Docker Containers**: Isolated execution environment per task
+- **Specialized VMs**: For tasks requiring full OS isolation
+- **Process Sandboxing**: Lightweight isolation for simple tasks
+
+**Transparency Requirements:**
+- Model perceives it's working on a local repository
+- Development tools available within sandbox
+- File system operations work normally from model's perspective
+- Network access controlled but transparent
+- Resource limits enforced but invisible
+
+## Development Plan
+
+### Phase 1: Model Provider Abstraction Layer
+
+#### 1.1 Create Provider Interface
+```go
+// pkg/ai/provider.go
+type ModelProvider interface {
+    ExecuteTask(ctx context.Context, request *TaskRequest) (*TaskResponse, error)
+    SupportsMCP() bool
+    SupportsTools() bool
+    GetCapabilities() []string
+}
+```
+
+#### 1.2 Implement Provider Types
+- **OllamaProvider**: Local model execution
+- **OpenAIProvider**: OpenAI API integration
+- **ResetDataProvider**: ResetData LaaS integration
+- **ProviderFactory**: Creates appropriate provider based on model config
+
+#### 1.3 Role-Model Configuration
+```yaml
+# Config structure for role-model mapping
+roles:
+  developer:
+    default_model: "codellama:13b"
+    provider: "ollama"
+    fallback_model: "llama3.1:8b"
+    fallback_provider: "resetdata"
+
+  architect:
+    default_model: "gpt-4o"
+    provider: "openai"
+    fallback_model: "llama3.1:8b"
+    fallback_provider: "ollama"
+```
+
+### Phase 2: Execution Environment Abstraction
+
+#### 2.1 Create Sandbox Interface
+```go
+// pkg/execution/sandbox.go
+type ExecutionSandbox interface {
+    Initialize(ctx context.Context, config *SandboxConfig) error
+    ExecuteCommand(ctx context.Context, cmd *Command) (*CommandResult, error)
+    CopyFiles(ctx context.Context, source, dest string) error
+    Cleanup() error
+}
+```
+
+#### 2.2 Implement Sandbox Types
+- **DockerSandbox**: Container-based isolation
+- **VMSandbox**: Full VM isolation for sensitive tasks
+- **ProcessSandbox**: Lightweight process-based isolation
+
+#### 2.3 Repository Mounting
+- Clone repository into sandbox environment
+- Mount as local filesystem from model's perspective
+- Implement secure file I/O operations
+- Handle git operations within sandbox
+
+### Phase 3: Core Task Execution Engine
+
+#### 3.1 Replace Mock Implementation
+Replace the current simulation in `coordinator/task_coordinator.go:314`:
+
+```go
+// Current mock implementation
+time.Sleep(10 * time.Second) // Simulate work
+
+// New implementation
+result, err := tc.executionEngine.ExecuteTask(ctx, &TaskExecutionRequest{
+    Task: activeTask.Task,
+    Agent: tc.agentInfo,
+    Sandbox: sandboxConfig,
+    ModelProvider: providerConfig,
+})
+```
+
+#### 3.2 Task Execution Strategies
+Create role-specific execution patterns:
+
+- **DeveloperStrategy**: Code implementation, bug fixes, feature development
+- **ReviewerStrategy**: Code review, quality analysis, test coverage assessment
+- **ArchitectStrategy**: System design, technical decision making
+- **TesterStrategy**: Test creation, validation, quality assurance
+
+#### 3.3 Execution Workflow
+1. **Task Analysis**: Parse task requirements and complexity
+2. **Environment Setup**: Initialize appropriate sandbox
+3. **Repository Preparation**: Clone and mount repository
+4. **Model Selection**: Choose appropriate model/provider
+5. **Task Execution**: Run role-specific execution strategy
+6. **Result Validation**: Verify output quality and completeness
+7. **Cleanup**: Teardown sandbox and collect artifacts
+
+### Phase 4: Repository Provider Implementation
+
+#### 4.1 Real Repository Integration
+Replace `MockTaskProvider` with actual implementations:
+- **GiteaProvider**: Integration with GITEA API
+- **GitHubProvider**: GitHub API integration
+- **GitLabProvider**: GitLab API integration
+
+#### 4.2 Task Lifecycle Management
+- Task claiming and status updates
+- Progress reporting back to repositories
+- Artifact attachment (patches, documentation, etc.)
+- Automated PR/MR creation for completed tasks
+
+### Phase 5: AI Integration and Tool Support
+
+#### 5.1 LLM Integration
+- Context-aware task analysis based on repository content
+- Code generation and problem-solving capabilities
+- Natural language processing for task descriptions
+- Multi-step reasoning for complex tasks
+
+#### 5.2 Tool Integration
+- MCP server connectivity within sandbox
+- Development tool access (compilers, linters, formatters)
+- Testing framework integration
+- Documentation generation tools
+
+#### 5.3 Quality Assurance
+- Automated testing of generated code
+- Code quality metrics and analysis
+- Security vulnerability scanning
+- Performance impact assessment
+
+### Phase 6: Testing and Validation
+
+#### 6.1 Unit Testing
+- Provider abstraction layer testing
+- Sandbox isolation verification
+- Task execution strategy validation
+- Error handling and recovery testing
+
+#### 6.2 Integration Testing
+- End-to-end task execution workflows
+- Agent-to-WHOOSH communication testing
+- Multi-provider failover scenarios
+- Concurrent task execution testing
+
+#### 6.3 Security Testing
+- Sandbox escape prevention
+- Resource limit enforcement
+- Network isolation validation
+- Secrets and credential protection
+
+### Phase 7: Production Deployment
+
+#### 7.1 Configuration Management
+- Environment-specific model configurations
+- Sandbox resource limit definitions
+- Provider API key management
+- Monitoring and logging setup
+
+#### 7.2 Monitoring and Observability
+- Task execution metrics and dashboards
+- Performance monitoring and alerting
+- Resource utilization tracking
+- Error rate and success metrics
+
+## Implementation Priorities
+
+### Critical Path (Week 1-2)

+2. Basic Docker Sandbox Implementation
+3. Replace Mock Task Execution
+4. Role-Based Execution Strategies
+
+### High Priority (Week 3-4)
+5. Real Repository Provider Implementation
+6. AI Integration with Ollama/OpenAI
+7. MCP Tool Integration
+8. Basic Testing Framework
+
+### Medium Priority (Week 5-6)

+
+## Success Metrics
+
+- **Task Completion Rate**: >90% of assigned tasks successfully completed
+- **Code Quality**: Generated code passes all existing tests and linting
+- **Security**: Zero sandbox escapes or security violations
+- **Performance**: Task execution time within acceptable bounds
+- **Reliability**: <5% execution failure rate due to engine issues
+
+## Risk Mitigation
+
+### Security Risks
+- Sandbox escape → Multiple isolation layers, security audits
+- Credential exposure → Secure credential management, rotation
+- Resource exhaustion → Resource limits, monitoring, auto-scaling
+
+### Technical Risks
+- Model provider outages → Multi-provider failover, local fallbacks

+- Performance bottlenecks → Profiling, optimization, horizontal scaling
+
+### Integration Risks
+- WHOOSH compatibility → Extensive integration testing, versioning
+- Repository provider changes → Provider abstraction, API versioning
+- Model compatibility → Provider abstraction, capability detection
+
+This comprehensive plan addresses the core limitation that CHORUS agents currently lack real task execution capabilities while building a robust, secure, and scalable execution engine suitable for production deployment.
+

+# CHORUS / WHOOSH Roadmap
+
+_Last updated: 2025-02-15_
+
+This roadmap translates the development plan into phased milestones with suggested sequencing and exit criteria. Durations are approximate and assume parallel work streams where practical.
+
+## Phase 0 – Kick-off & Scoping (Week 0)
+- Confirm owners and staffing for SLURP, SHHH, COOEE, WHOOSH, UCXL, and KACHING work streams.
+- Finalize engineering briefs for each deliverable; align with plan in `CHORUS-WHOOSH-development-plan.md`.
+- Stand up tracking board (Kanban/Sprint) with milestone tags introduced below.
+
+**Exit Criteria**
+- Owners assigned and briefs approved.
+- Roadmap milestones added to tracking tooling.
+
+## Phase 1 – Security Substrate Foundations (Weeks 1–4)
+- **1.1 SLURP Core (Weeks 1–3)**
+  - Implement storage/resolver/temporal components and leader integration (ticket group `SEC-SLURP`).
+  - Ship integration tests covering admin-only operations and failover.
+- **1.2 SHHH Sentinel (Weeks 2–4)**
+  - Build `pkg/shhh`, integrate with COOEE/WHOOSH logging, add audit metrics (`SEC-SHHH`).
+- **1.3 COOEE Mesh Monitoring (Weeks 3–4)**
+  - Validate enrolment payloads, instrument mesh health, document ops runbook (`SEC-COOEE`).
+
+**Exit Criteria**
+- SLURP passes integration suite with real context resolution.
+- SHHH redaction events visible in metrics/logs; regression tests in place.
+- COOEE dashboards/reporting operational; runbook published.
+
+## Phase 2 – WHOOSH Data Path & Telemetry (Weeks 4–8)
+- **2.1 Persistence & API Hardening (Weeks 4–6)**
+  - Replace mock handlers with Postgres-backed endpoints (`WHOOSH-API`).
+- **2.2 Analysis Ingestion (Weeks 5–7)**
+  - Pipeline real Gitea/n8n analysis into composer/monitor (`WHOOSH-ANALYSIS`).
+- **2.3 Deployment Telemetry (Weeks 6–8)**
+  - Persist deployment results, emit telemetry, surface status in UI (`WHOOSH-OBS`).
+- **2.4 Composer Enhancements (Weeks 7–8)**
+  - Add LLM skill analysis with fallback heuristics; evaluation harness (`WHOOSH-COMP`).
+
+**Exit Criteria**
+- WHOOSH API/UI reflects live database state.
+- Analysis-derived data present in team formation/deployment flows.
+- Telemetry events available for KACHING integration.
+
+## Phase 3 – Cross-Cutting Governance & Tooling (Weeks 8–12)
+- **3.1 UCXL Spec & Validator (Weeks 8–10)**
+  - Publish Spec 1.0, ship validator CLI with CI coverage (`UCXL-SPEC`).
+- **3.2 KACHING Telemetry (Weeks 9–11)**
+  - Instrument CHORUS runtime & WHOOSH orchestrator, deploy ingestion/aggregation jobs (`KACHING-TELEM`).
+- **3.3 Governance Tooling (Weeks 10–12)**
+  - Deliver DR templates, signed assertions workflow, scope-aware RUSTLE views (`GOV-TOOLS`).
+
+**Exit Criteria**
+- UCXL validator integrated into CI for CHORUS/WHOOSH/RUSTLE.
+- KACHING receives events and triggers quota/budget alerts.
+- Governance docs/tooling published; RUSTLE displays redacted context correctly.
+
+## Phase 4 – Stabilization & Launch Readiness (Weeks 12–14)
+- Regression testing across CHORUS/WHOOSH/UCXL/KACHING.
+- Security & compliance review for SHHH and telemetry pipelines.
+- Rollout plan: staged deployment, rollback procedures, support playbooks.
+
+**Exit Criteria**
+- All milestone tickets closed with QA sign-off.
+- Production readiness review approved; launch window scheduled.
+
+## Tracking & Reporting
+- Weekly status sync covering milestone burndown, risks, and cross-team blockers.
+- Metrics dashboard to include: SLURP leader uptime, SHHH redaction counts, COOEE peer health, WHOOSH deployment success rate, UCXL validation pass rate, KACHING alert volume.
+- Maintain Decision Records for key architecture/security choices at relevant UCXL addresses.

+// redaction rules, emitting audit events, and tracking operational metrics.
+//
+// The initial implementation focuses on high-signal secrets (API keys,

+# 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 ./...
+```

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
