SLURP Core Context Implementation Summary

Overview

This document summarizes the implementation of the core SLURP contextual intelligence system for the BZZZ project. The implementation provides production-ready Go code that seamlessly integrates with existing BZZZ systems including UCXL addressing, role-based encryption, DHT distribution, and leader election.

Implemented Components

1. Core Context Types (pkg/slurp/context/types.go)

Key Types Implemented:

• ContextNode: Hierarchical context nodes with BZZZ integration
• RoleAccessLevel: Encryption levels matching BZZZ authority hierarchy
• EncryptedContext: Role-encrypted context data for DHT storage
• ResolvedContext: Final resolved context with resolution metadata
• ContextError: Structured error handling with BZZZ patterns

Integration Features:

• UCXL Address Integration: Direct integration with pkg/ucxl/address.go
• Role Authority Mapping: Maps config.AuthorityLevel to RoleAccessLevel
• Validation Functions: Comprehensive validation with meaningful error messages
• Clone Methods: Deep copying for safe concurrent access
• Access Control: Role-based access checking with authority levels

2. Context Resolver Interfaces (pkg/slurp/context/resolver.go)

Core Interfaces Implemented:

• ContextResolver: Main resolution interface with bounded hierarchy traversal
• HierarchyManager: Manages context hierarchy with depth limits
• GlobalContextManager: Handles system-wide contexts
• CacheManager: Performance caching for context resolution
• ContextMerger: Merges contexts using inheritance rules
• ContextValidator: Validates context quality and consistency

Helper Functions:

• Request Validation: Validates resolution requests with proper error handling
• Confidence Calculation: Weighted confidence scoring from multiple contexts
• Role Filtering: Filters contexts based on role access permissions
• Cache Key Generation: Consistent cache key generation
• String Merging: Deduplication utilities for merging context data

BZZZ System Integration

1. UCXL Address System Integration

// Direct integration with existing UCXL address parsing
type ContextNode struct {
    UCXLAddress ucxl.Address `json:"ucxl_address"`
    // ... other fields
}

// Validation uses existing UCXL validation
if err := cn.UCXLAddress.Validate(); err != nil {
    return NewContextError(ErrorTypeValidation, ErrorCodeInvalidAddress, 
        "invalid UCXL address").WithUnderlying(err).WithAddress(cn.UCXLAddress)
}

2. Role-Based Access Control Integration

// Maps BZZZ authority levels to context access levels
func AuthorityToAccessLevel(authority config.AuthorityLevel) RoleAccessLevel {
    switch authority {
    case config.AuthorityMaster:
        return AccessCritical
    case config.AuthorityDecision:
        return AccessHigh
    // ... etc
    }
}

// Role-based access checking
func (cn *ContextNode) CanAccess(role string, authority config.AuthorityLevel) bool {
    if authority == config.AuthorityMaster {
        return true // Master authority can access everything
    }
    // ... additional checks
}

3. Comprehensive Error Handling

// Structured errors with BZZZ patterns
type ContextError struct {
    Type        string            `json:"type"`
    Message     string            `json:"message"`
    Code        string            `json:"code"`
    Address     *ucxl.Address     `json:"address"`
    Context     map[string]string `json:"context"`
    Underlying  error             `json:"underlying"`
}

// Error creation with chaining
func NewContextError(errorType, code, message string) *ContextError
func (e *ContextError) WithAddress(address ucxl.Address) *ContextError
func (e *ContextError) WithContext(key, value string) *ContextError
func (e *ContextError) WithUnderlying(err error) *ContextError

Usage Examples

Basic Context Resolution

resolver := NewContextResolver(config, dht, crypto)
ctx := context.Background()
address, _ := ucxl.Parse("ucxl://agent:backend@project:task/*^/src/main.go")

resolved, err := resolver.Resolve(ctx, *address, "backend_developer")
if err != nil {
    // Handle context error with structured information
    if contextErr, ok := err.(*ContextError); ok {
        log.Printf("Context error [%s:%s]: %s", 
            contextErr.Type, contextErr.Code, contextErr.Message)
    }
}

Batch Resolution

request := &BatchResolutionRequest{
    Addresses: []ucxl.Address{addr1, addr2, addr3},
    Role:      "senior_software_architect", 
    MaxDepth:  10,
}

result, err := resolver.BatchResolve(ctx, request)
if err != nil {
    return err
}

for addrStr, resolved := range result.Results {
    // Process resolved context
}

Context Creation with Validation

contextNode := &ContextNode{
    Path:        "/path/to/file",
    UCXLAddress: *address,
    Summary:     "Component summary",
    Purpose:     "What this component does",
    Technologies: []string{"go", "docker"},
    Tags:        []string{"backend", "api"},
    AccessLevel: AccessHigh,
    EncryptedFor: []string{"backend_developer", "senior_software_architect"},
}

if err := contextNode.Validate(); err != nil {
    return fmt.Errorf("context validation failed: %w", err)
}
