+# SLURP Temporal Decision Graph System
+
+The Temporal Decision Graph System implements decision-hop based temporal analysis, tracking how context and decisions evolve through decision relationships rather than chronological time.
+
+## Purpose
+
+This module provides:
+
+- **Decision-Based Temporal Analysis**: Track related decisions by decision distance, not time
+- **Context Evolution**: Monitor how understanding deepens over time
+- **Decision Influence Graphs**: Map how decisions affect other decisions
+- **Temporal Queries**: Query context "as it was" at any decision point
+- **Decision Genealogy**: Track the lineage and rationale of decisions
+
+## Key Innovation: Decision Hops vs Time
+
+Traditional temporal systems track changes chronologically. SLURP's temporal system tracks changes by **decision relationships**:
+
+- **Decision Hop 0**: Original context/decision
+- **Decision Hop 1**: Decisions directly influenced by the original
+- **Decision Hop 2**: Decisions influenced by hop-1 decisions
+- **Decision Hop N**: N-degrees of decision influence away
+
+This provides **conceptual relevance** similar to RAG systems - finding related decisions by influence rather than time proximity.
+
+## Architecture
+
+### Core Components
+
+#### TemporalContextNode
+```python
+@dataclass
+class TemporalContextNode:
+    ucxl_address: str          # What file/component this affects
+    timestamp: str             # When the decision occurred
+    version: int               # Monotonic version number
+    
+    # Context at this decision point
+    summary: str
+    purpose: str
+    technologies: List[str]
+    tags: List[str]
+    insights: List[str]
+    
+    # Decision metadata
+    change_reason: ContextChangeReason  # Why context changed
+    parent_version: Optional[int]       # Previous version
+    decision_metadata: DecisionMetadata # Who, why, how confident
+    
+    # Decision influence graph
+    influences: List[str]      # UCXL addresses this decision influences
+    influenced_by: List[str]   # UCXL addresses that influenced this
+```
+
+#### DecisionMetadata
+```python
+@dataclass
+class DecisionMetadata:
+    decision_maker: str         # Who made the decision
+    decision_id: Optional[str]  # Git commit, ticket ID, etc.
+    decision_rationale: str     # Why the decision was made
+    impact_scope: str          # local, module, project, system
+    confidence_level: float    # How confident in this decision
+    external_references: List[str]  # Links to PRs, issues, docs
+```
+
+### Decision Change Reasons
+
+The system tracks **why** context changes:
+
+- `INITIAL_CREATION`: First context creation
+- `CODE_CHANGE`: File/code modifications
+- `DESIGN_DECISION`: Architectural or design choices
+- `REFACTORING`: Code structure improvements
+- `ARCHITECTURE_CHANGE`: System-wide architectural changes
+- `REQUIREMENTS_CHANGE`: Changed requirements/specifications
+- `LEARNING_EVOLUTION`: Improved understanding over time
+- `RAG_ENHANCEMENT`: RAG system provided better insights
+- `TEAM_INPUT`: Human team member input/corrections
+- `BUG_DISCOVERY`: Found issues that change understanding
+- `PERFORMANCE_INSIGHT`: Performance analysis changed context
+- `SECURITY_REVIEW`: Security analysis added context
+
+## Key Features
+
+### Decision-Hop Analysis
+```python
+# Find all decisions within 3 hops of a component
+related_decisions = temporal_graph.find_related_decisions(
+    "ucxl://any:any@BZZZ:RUSTLE-testing/src/main.rs", 
+    max_hops=3
+)
+
+# Get decision timeline (by decision influence, not time)
+timeline = temporal_graph.get_decision_timeline(
+    ucxl_address, 
+    include_related=True, 
+    max_hops=2
+)
+```
+
+### Decision Path Discovery
+```python
+# Find shortest decision path between two components
+path = temporal_graph.find_decision_path(
+    from_address="ucxl://any:any@BZZZ:RUSTLE-testing/src/main.rs",
+    to_address="ucxl://any:any@BZZZ:RUSTLE-testing/src/api.rs"
+)
+```
+
+### Context Time Travel
+```python
+# Get context as it was at a specific decision point
+historical_context = temporal_graph.get_version_at_time(
+    ucxl_address, 
+    target_time=datetime(2024, 1, 15)
+)
+
+# Get complete evolution history
+evolution = temporal_graph.get_context_evolution(ucxl_address)
+```
+
+### Confidence Evolution Tracking
+The system tracks how confidence in context changes over time:
+
+```python
+confidence_adjustments = {
+    RAG_ENHANCEMENT: +0.1,      # RAG usually improves confidence
+    TEAM_INPUT: +0.15,          # Human input is valuable
+    LEARNING_EVOLUTION: +0.1,   # Learning improves understanding
+    BUG_DISCOVERY: -0.15,       # Bugs indicate misunderstanding
+    ARCHITECTURE_CHANGE: -0.05, # Major changes create uncertainty
+}
+```
+
+## Decision Influence Propagation
+
+When a decision changes context, it propagates influence to related components:
+
+1. **Direct Influence**: Components directly affected by the decision
+2. **Indirect Influence**: Components affected by the directly influenced ones
+3. **Staleness Propagation**: Increases staleness indicator for affected contexts
+4. **Re-analysis Triggers**: May trigger automated re-analysis of stale contexts
+
+### Staleness Calculation
+```python
+def calculate_staleness_impact(reason, impact_scope):
+    base_staleness = {
+        "local": 0.1,
+        "module": 0.3, 
+        "project": 0.5,
+        "system": 0.8
+    }[impact_scope]
+    
+    reason_multipliers = {
+        ARCHITECTURE_CHANGE: 2.0,
+        REQUIREMENTS_CHANGE: 1.5,
+        REFACTORING: 1.2,
+        CODE_CHANGE: 1.0
+    }
+    
+    return base_staleness * reason_multipliers.get(reason, 1.0)
+```
+
+## Integration with BZZZ Leader System
+
+### Leader-Coordinated Temporal Updates
+- **Leader Authority**: Only Leader can create new temporal context versions
+- **Decision Validation**: Leader validates and approves decision metadata
+- **Consistency Guarantee**: Single source of truth for decision evolution
+- **Failover Handling**: Temporal graph transfers with leadership election
+
+### Role-Based Temporal Access
+- **Decision Visibility**: Agents see temporal context relevant to their role
+- **Encrypted Temporal Data**: Decision history encrypted per role
+- **Need-to-Know Temporal**: Only relevant decision paths visible
+- **Audit Trail**: Complete log of temporal context access
+
+## Query Patterns
+
+### Temporal Context Queries
+```python
+# What decisions led to this current state?
+decision_path = get_decision_ancestry(ucxl_address)
+
+# What would be affected if I change this component?
+impact_analysis = find_decision_influence_cone(ucxl_address, max_depth=5)
+
+# Show me all decisions made by this person/system
+maker_decisions = filter_decisions_by_maker("tony")
+
+# Find components that evolved similarly to this one
+similar_evolution = find_similar_decision_patterns(ucxl_address)
+```
+
+### Decision Pattern Analysis
+```python
+# Analyze decision-making patterns over time
+patterns = temporal_graph.analyze_decision_patterns()
+# Returns:
+# - decision_makers: Who makes what types of decisions
+# - change_reasons: Most common reasons for context changes  
+# - impact_scopes: Distribution of decision impact levels
+# - decision_frequency: Decision activity over time
+```
+
+## Performance Characteristics
+
+### Decision Graph Traversal
+- **Bounded Depth**: Configurable maximum decision hop depth
+- **Efficient Pathfinding**: Breadth-first search with early termination
+- **Cached Relationships**: In-memory caching of decision relationships
+- **Lazy Loading**: Load decision details only when needed
+
+### Storage Efficiency
+- **Differential Versioning**: Only store changes between versions
+- **Decision Deduplication**: Reuse common decision metadata
+- **Compressed History**: Compress old temporal data
+- **Index Optimization**: Efficient indexing for temporal queries
+
+## Use Cases
+
+### Architectural Decision Tracking
+- **Why was this design chosen?**: Trace back through decision genealogy
+- **What else was affected?**: Find all components influenced by a decision
+- **Who should review changes?**: Identify decision makers for related components
+- **Risk Assessment**: Understand decision confidence and validation history
+
+### Impact Analysis
+- **Change Impact**: What decisions would be affected by this change?
+- **Regression Risk**: Has similar context been changed before? What happened?
+- **Knowledge Transfer**: New team members can see decision rationale history
+- **Technical Debt**: Identify areas with low-confidence or outdated decisions
+
+### Learning and Optimization
+- **Decision Quality**: Track which types of decisions lead to better outcomes
+- **Team Patterns**: Understand how different team members make decisions
+- **Context Staleness**: Identify areas needing decision review/update
+- **Knowledge Evolution**: See how understanding improved over time
+
+## Future Enhancements
+
+- **ML-Based Decision Prediction**: Predict likely next decisions based on patterns
+- **Automated Staleness Detection**: ML models to identify potentially stale context
+- **Decision Recommendation**: Suggest reviewers based on decision history
+- **Cross-Project Decision Learning**: Learn from decisions across multiple projects
+- **Real-time Decision Streaming**: WebSocket-based decision update notifications

+Temporal Context Evolution System
+
+Implements a temporal graph network for tracking how context and decisions evolve over time.
+
+Key concepts:
+- Temporal Nodes: Context at specific points in time
+- Decision Points: When context changes due to decisions/events
+- Context Evolution: How understanding deepens over time
+- Temporal Queries: Query context "as it was" at any point in time
+- Decision Tracking: Why context changed (git commits, design decisions, etc.)
+
+This addresses your insight that decisions change over time and we need to track
+the evolution of understanding and context within the project.
