Add comprehensive tests for PathConfidenceScorer, PathEnumerator, ShellSymbolicExecutor, and SymbolicState
- Implemented unit tests for PathConfidenceScorer to evaluate path scoring under various conditions, including empty constraints, known and unknown constraints, environmental dependencies, and custom weights. - Developed tests for PathEnumerator to ensure correct path enumeration from simple scripts, handling known environments, and respecting maximum paths and depth limits. - Created tests for ShellSymbolicExecutor to validate execution of shell scripts, including handling of commands, branching, and environment tracking. - Added tests for SymbolicState to verify state management, variable handling, constraint addition, and environment dependency collection.

|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
### Symbolic State Model
|
||||
|
||||
```csharp
|
||||
/// State during symbolic execution
|
||||
SymbolicState := {
|
||||
Variables: ImmutableDictionary<string, SymbolicValue>,
|
||||
CurrentPath: ExecutionPath,
|
||||
PathCondition: ImmutableArray<PathConstraint>,
|
||||
Depth: int,
|
||||
TerminalCommands: ImmutableArray<TerminalCommand>,
|
||||
}
|
||||
|
||||
/// Algebraic type for symbolic values
|
||||
SymbolicValue := Concrete(value)
|
||||
| Symbolic(name, constraints)
|
||||
| Unknown(reason)
|
||||
| Composite(parts)
|
||||
|
||||
/// Path constraint for satisfiability checking
|
||||
PathConstraint := {
|
||||
Expression: string,
|
||||
IsNegated: bool,
|
||||
Source: ShellSpan,
|
||||
DependsOnEnv: ImmutableArray<string>,
|
||||
}
|
||||
```
|
||||
|
||||
### Execution Tree Model
|
||||
|
||||
```csharp
|
||||
ExecutionTree := {
|
||||
Root: ExecutionNode,
|
||||
AllPaths: ImmutableArray<ExecutionPath>,
|
||||
BranchPoints: ImmutableArray<BranchPoint>,
|
||||
Coverage: BranchCoverage,
|
||||
}
|
||||
|
||||
ExecutionPath := {
|
||||
Id: string,
|
||||
PathId: string, // Deterministic hash
|
||||
Constraints: PathConstraint[],
|
||||
TerminalCommands: TerminalCommand[],
|
||||
ReachabilityConfidence: float,
|
||||
IsFeasible: bool, // False if constraints unsatisfiable
|
||||
}
|
||||
|
||||
BranchPoint := {
|
||||
Location: ShellSpan,
|
||||
BranchKind: BranchKind, // If, Elif, Else, Case
|
||||
Predicate: string,
|
||||
TakenPaths: int,
|
||||
TotalPaths: int,
|
||||
DependsOnEnv: string[],
|
||||
}
|
||||
|
||||
BranchCoverage := {
|
||||
TotalBranches: int,
|
||||
CoveredBranches: int,
|
||||
CoverageRatio: float,
|
||||
UnreachableBranches: int,
|
||||
EnvDependentBranches: int,
|
||||
}
|
||||
```
|
||||
|
||||
### Constraint Solving
|
||||
|
||||
```csharp
|
||||
/// Evaluates path feasibility
|
||||
IConstraintEvaluator {
|
||||
EvaluateAsync(constraints) -> ConstraintResult {Feasible, Infeasible, Unknown}
|
||||
SimplifyAsync(constraints) -> PathConstraint[]
|
||||
}
|
||||
|
||||
/// Built-in patterns for common shell conditionals:
|
||||
/// - [ -z "$VAR" ] -> Variable is empty
|
||||
/// - [ -n "$VAR" ] -> Variable is non-empty
|
||||
/// - [ "$VAR" = "value" ] -> Equality check
|
||||
/// - [ -f "$PATH" ] -> File exists
|
||||
/// - [ -d "$PATH" ] -> Directory exists
|
||||
/// - [ -x "$PATH" ] -> File is executable
|
||||
```
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- [ ] SymbolicState tracks variable bindings through execution
|
||||
- [ ] PathEnumerator explores all branches in if/elif/else and case/esac
|
||||
- [ ] ConstraintEvaluator detects infeasible paths (contradictory conditions)
|
||||
- [ ] BranchCoverage calculates coverage metrics accurately
|
||||
- [ ] Integration with existing ShellParser nodes works seamlessly
|
||||
- [ ] Unit test coverage ≥ 85%
|
||||
- [ ] All outputs deterministic (stable path IDs, ordering)
|
||||
|
||||
## Effort Estimate
|
||||
|
||||
**Size:** Large (L) - 5-7 days
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Use algebraic SymbolicValue type | Clean modeling of concrete, symbolic, and unknown values |
|
||||
| Pattern-based constraint evaluation | Cover 90% of shell conditionals with patterns; no SMT solver needed |
|
||||
| Depth-limited path enumeration | Prevent explosion; configurable limit with warning |
|
||||
| Integrate with ShellParser AST | Reuse existing parsing infrastructure |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Path explosion in complex scripts | Add depth limit; prune infeasible paths early |
|
||||
| Environment variable complexity | Mark env-dependent paths; don't guess values |
|
||||
| Command substitution side effects | Model as Unknown with reason; don't execute |
|
||||
| Incomplete constraint patterns | Start with common patterns; extensible design |
|
||||
|
||||

||||
|
||||
```csharp

## Effort Estimate
|
||||
|

**Size:** Large (L) - 5-7 days
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Use multi-algorithm fingerprinting | Different algorithms for different scenarios |
|
||||
| In-memory index first | Fast iteration; disk-backed index later |
|
||||
| Confidence-scored matches | Allow for partial/fuzzy matches |
|
||||
| PURL-based source tracking | Consistent with SBOM ecosystem |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Large fingerprint corpus | Lazy loading, tiered caching |
|
||||
| Fingerprint collisions | Multi-algorithm verification |
|
||||
| Stripped binary complexity | Pattern-based fallbacks |
|
||||
| Cross-architecture differences | Normalize before fingerprinting |
|
||||

|
||||
- Combine semantic intent, temporal drift, mesh exposure, speculative paths, and binary intelligence into unified risk metrics.
|
||||
- Enable queries like "Show me the 10 images with highest risk of exploitation this week."
|
||||
- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.EntryTrace/Risk/`

|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
### Risk Score Model
|
||||
|
||||
```csharp
|
||||
/// Multi-dimensional risk score
|
||||
RiskScore := {
|
||||
OverallScore: float, // Normalized 0.0-1.0
|
||||
Category: RiskCategory, // Primary risk category
|
||||
Confidence: float, // Confidence in assessment
|
||||
ComputedAt: DateTimeOffset, // When score was computed
|
||||
}
|
||||
|
||||
/// Risk categories for classification
|
||||
RiskCategory := {
|
||||
Exploitability, // Known CVE with exploit available
|
||||
Exposure, // Internet-facing, publicly reachable
|
||||
Privilege, // Runs as root, elevated capabilities
|
||||
DataSensitivity, // Accesses sensitive data
|
||||
BlastRadius, // Can affect many other services
|
||||
DriftVelocity, // Rapid changes indicate instability
|
||||
Unknown, // Insufficient data
|
||||
}
|
||||
|
||||
/// Individual contributing factor to risk
|
||||
RiskFactor := {
|
||||
Name: string, // Factor identifier
|
||||
Category: RiskCategory, // Risk category
|
||||
Contribution: float, // Weight in overall score
|
||||
Evidence: string, // Human-readable evidence
|
||||
SourceId: string?, // Link to source data (CVE, drift, etc.)
|
||||
}
|
||||
```
|
||||
|
||||
### Risk Assessment Aggregate
|
||||
|
||||
```csharp
|
||||
/// Complete risk assessment for an image/container
|
||||
RiskAssessment := {
|
||||
SubjectId: string, // Image digest or container ID
|
||||
SubjectType: SubjectType, // Image, Container, Service
|
||||
OverallScore: RiskScore, // Synthesized risk
|
||||
Factors: RiskFactor[], // All contributing factors
|
||||
BusinessContext: BusinessContext?,
|
||||
TopRecommendations: string[], // Actionable recommendations
|
||||
AssessedAt: DateTimeOffset,
|
||||
}
|
||||
|
||||
/// Business context for risk weighting
|
||||
BusinessContext := {
|
||||
Environment: string, // production, staging, dev
|
||||
IsInternetFacing: bool, // Exposed to internet
|
||||
DataClassification: string, // public, internal, confidential, restricted
|
||||
CriticalityTier: int, // 1=mission-critical, 3=best-effort
|
||||
ComplianceRegimes: string[], // PCI-DSS, HIPAA, SOC2, etc.
|
||||
}
|
||||
```
|
||||
|
||||
## Size Estimate
|
||||
**Size:** Medium (M) - 3-5 days
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Multi-dimensional scoring | Single scores lose nuance; categories enable targeted action |
|
||||
| Business context weighting | Same technical risk differs by business impact |
|
||||
| Factor-based decomposition | Explainable AI requirement; auditable scores |
|
||||
| Confidence tracking | Scores are less useful without uncertainty bounds |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Score gaming | Track score computation provenance; detect anomalies |
|
||||
| Stale risk data | Short TTLs; refresh on new intelligence |
|
||||
| False sense of security | Always show confidence intervals; highlight unknowns |
|
||||
| Incomplete context | Degrade gracefully with partial data |
|
||||
|
||||
## Execution Log
|
||||
|
||||
| Date (UTC) | Update | Owner |
|
||||

|
||||
| 2025-12-20 | DOC-001 DONE: Updated AGENTS.md with full Risk module contracts. Sprint 0415 core implementation complete; tests TODO. | Agent |
