+# 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
+```go
+// 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
+```go
+// 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
+```go
+// 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
+```go

+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
+```go
+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
+```go
+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)
+}
+```
