Documentation Statistics (Phase 2):
- 7 package files created (~12,000 lines total)
- Complete API reference for all exported symbols
- Line-by-line source code analysis
- 30+ usage examples across packages
- Implementation status tracking (Production/Beta/Alpha/TODO)

### Graceful Shutdown Setup
```go
// Lines 266-323 in agent_support.go
func (r *SharedRuntime) setupGracefulShutdown(
shutdownManager *shutdown.Manager,
healthManager *health.Manager,
)
```
**Shutdown Order** (by priority, higher = later):
| Priority | Component | Timeout | Critical |
|----------|-----------|---------|----------|
| 10 | HTTP API Server | Default | Yes |
| 15 | Health Manager | Default | Yes |
| 20 | UCXI Server | Default | Yes |
| 30 | PubSub | Default | Yes |
| 35 | DHT Node | Default | Yes |
| 40 | P2P Node | Default | Yes |
| 45 | Election Manager | Default | Yes |
| 50 | BACKBEAT Integration | Default | Yes |
**Why This Order:**
1. Stop accepting new requests (HTTP)
2. Stop health reporting
3. Stop content resolution (UCXI)
4. Stop broadcasting messages (PubSub)
5. Stop DHT queries/storage
6. Close P2P connections
7. Stop election participation
8. Disconnect BACKBEAT telemetry
---
## Cleanup Flow
### Function: Cleanup()
```go
// Lines 302-344 in shared.go
func (r *SharedRuntime) Cleanup()
```
**Manual Cleanup** (used if StartAgentMode not called):
```
1. Stop BACKBEAT Integration (line 306)
2. Close mDNS Discovery (lines 310-312)
3. Close PubSub (lines 314-316)
4. Close DHT Node (lines 318-320)
5. Close P2P Node (lines 322-324)
6. Stop HTTP Server (lines 326-328)
7. Stop UCXI Server (lines 330-332)
8. Stop Election Manager (lines 334-336)
9. Cancel Context (lines 338-340)
10. Log completion (line 343)
```
**Note:** If `StartAgentMode()` is called, graceful shutdown manager handles cleanup automatically.

## Helper Types
### SimpleLogger
```go
// Lines 44-57 in shared.go
type SimpleLogger struct{}
func (l *SimpleLogger) Info(msg string, args ...interface{})
func (l *SimpleLogger) Warn(msg string, args ...interface{})
func (l *SimpleLogger) Error(msg string, args ...interface{})
```
**Purpose:** Basic logging implementation for runtime components
**Output:** Uses `log.Printf()` with level prefixes
### SimpleTaskTracker
```go
// Lines 59-106 in shared.go
type SimpleTaskTracker struct {
maxTasks int
activeTasks map[string]bool
decisionPublisher *ucxl.DecisionPublisher
}
```
**Methods:**
| Method | Purpose |
|--------|---------|
| `GetActiveTasks() []string` | Returns list of active task IDs |
| `GetMaxTasks() int` | Returns max concurrent tasks |
| `AddTask(taskID string)` | Marks task as active |
| `RemoveTask(taskID string)` | Marks task complete, publishes decision |
**Decision Publishing:**
- When task completes, publishes to DHT via UCXL
- Only if `decisionPublisher` is set
- Includes: task ID, success status, summary, modified files
---
## AI Provider Configuration
### Function: initializeAIProvider()
```go
// Lines 620-686 in shared.go
func initializeAIProvider(cfg *config.Config, logger *SimpleLogger) error
```
**Supported Providers:**
1. **ResetData** (lines 627-640)
```go
reasoning.SetAIProvider("resetdata")
reasoning.SetResetDataConfig(reasoning.ResetDataConfig{
BaseURL: cfg.AI.ResetData.BaseURL,
APIKey: cfg.AI.ResetData.APIKey,
Model: cfg.AI.ResetData.Model,
Timeout: cfg.AI.ResetData.Timeout,
})
```
2. **Ollama** (lines 642-644)
```go
reasoning.SetAIProvider("ollama")
reasoning.SetOllamaEndpoint(cfg.AI.Ollama.Endpoint)
```
3. **Default** (lines 646-660)
- Falls back to ResetData if unknown provider
- Logs warning
**Model Configuration** (lines 662-667):
```go
reasoning.SetModelConfig(
cfg.Agent.Models,
cfg.Agent.ModelSelectionWebhook,
cfg.Agent.DefaultReasoningModel,
)
```
**Prompt Initialization** (lines 669-683):
- Read prompts from `CHORUS_PROMPTS_DIR`
- Read default instructions from `CHORUS_DEFAULT_INSTRUCTIONS_PATH`
- Compose role-specific system prompt if role configured
- Fall back to default instructions if no role
---
## SHHH Integration
### Audit Sink
```go
// Lines 609-618 in shared.go
type shhhAuditSink struct {
logger *SimpleLogger
}
func (s *shhhAuditSink) RecordRedaction(_ context.Context, event shhh.AuditEvent)
```
**Purpose:** Logs all SHHH redaction events
**Log Format:**
```
[WARN] 🔒 SHHH redaction applied (rule=api_key severity=high path=/workspace/data/config.json)
```
### Findings Observer
```go
// Lines 600-607 in shared.go
func (r *SharedRuntime) handleShhhFindings(ctx context.Context, findings []shhh.Finding)
```
**Purpose:** Records SHHH findings in metrics
**Implementation:**
```go
for _, finding := range findings {
r.Metrics.IncrementSHHHFindings(
finding.Rule,
string(finding.Severity),
finding.Count,
)
}
```
---
## Configuration Integration
### Environment Loading
**Performed in Initialize()** (line 149):
```go
cfg, err := config.LoadFromEnvironment()
```
**See:** `pkg/config` documentation for complete environment variable reference
### Assignment Loading
**Dynamic Assignment** (lines 160-176):
```go
if assignURL := os.Getenv("ASSIGN_URL"); assignURL != "" {
runtime.Logger.Info("📡 Loading assignment from WHOOSH: %s", assignURL)
ctx, cancel := context.WithTimeout(runtime.Context, 10*time.Second)
if err := runtime.RuntimeConfig.LoadAssignment(ctx, assignURL); err != nil {
runtime.Logger.Warn("⚠️ Failed to load assignment: %v", err)
} else {
runtime.Logger.Info("✅ Assignment loaded successfully")
}
cancel()
// Start reload handler for SIGHUP
runtime.RuntimeConfig.StartReloadHandler(runtime.Context, assignURL)
}
```
**SIGHUP Reload:**
- Send `kill -HUP <pid>` to reload assignment
- No restart required
- Updates: bootstrap peers, role, expertise, max tasks, etc.
---
## Usage Examples
### Example 1: Basic Initialization (Agent)
```go
package main
import (
"fmt"
"os"
"chorus/internal/runtime"
)
func main() {
// Set build info
runtime.AppVersion = "1.0.0"
runtime.AppCommitHash = "abc123"
runtime.AppBuildDate = "2025-09-30"
// Initialize runtime
rt, err := runtime.Initialize("agent")
if err != nil {
fmt.Fprintf(os.Stderr, "Failed to initialize: %v\n", err)
os.Exit(1)
}
defer rt.Cleanup()
// Start agent mode (blocks until shutdown)
if err := rt.StartAgentMode(); err != nil {
fmt.Fprintf(os.Stderr, "Agent mode failed: %v\n", err)
os.Exit(1)
}
}
```
### Example 2: Custom HAP Mode
```go
func main() {
runtime.AppVersion = "1.0.0"
rt, err := runtime.Initialize("hap")
if err != nil {
fmt.Fprintf(os.Stderr, "Failed to initialize: %v\n", err)
os.Exit(1)
}
defer rt.Cleanup()
// HAP mode: manual interaction instead of StartAgentMode()
terminal := hapui.NewTerminalInterface(rt)
if err := terminal.Start(); err != nil {
fmt.Fprintf(os.Stderr, "Terminal failed: %v\n", err)
os.Exit(1)
}
}
```
### Example 3: Accessing Components
```go
func main() {
rt, _ := runtime.Initialize("agent")
defer rt.Cleanup()
// Access initialized components
nodeID := rt.Node.ID().ShortString()
fmt.Printf("Node ID: %s\n", nodeID)
// Publish custom message
rt.PubSub.Publish("chorus/custom", []byte("hello"))
// Store data in DHT
if rt.EncryptedStorage != nil {
rt.EncryptedStorage.Put(context.Background(), "key", []byte("value"))
}
// Check if this node is admin
if rt.ElectionManager.IsAdmin() {
fmt.Println("This node is admin")
}
// Start agent behaviors
rt.StartAgentMode()
}
```
