# Elenchus Implementation Status
> Last Updated: 2024-01-17
> Status: In Progress
---
## 1. Completed Implementations
### 1.1 Issue Lifecycle Management
**Location**: `src/lifecycle/index.ts`, `src/types/index.ts`
```typescript
// New Issue Statuses
type IssueStatus = 'RAISED' | 'CHALLENGED' | 'RESOLVED' | 'UNRESOLVED'
| 'DISMISSED' | 'MERGED' | 'SPLIT';
// Transition Types
type IssueTransitionType = 'DISCOVERED' | 'ESCALATED' | 'DEMOTED'
| 'MERGED_INTO' | 'SPLIT_FROM' | 'INVALIDATED'
| 'VALIDATED' | 'REFINED';
```
**Functions**:
- `detectIssueTransitions()` - Detects transitions from round output
- `applyTransition()` - Records state transitions
- `mergeIssues()` - Merges duplicate issues
- `splitIssue()` - Splits complex issues
- `changeSeverity()` - Escalates/demotes severity
### 1.2 Exhaustive Verification System
**Location**: `src/roles/definitions.ts`
**New Verifier Validations**:
| ID | Description | Severity |
|----|-------------|----------|
| V005 | ALL 5 categories must be covered | ERROR |
| V006 | Negative assertions required | WARNING |
| V007 | Edge case analysis required | ERROR |
| V008 | Must address Critic FLAGs | ERROR |
**New Critic Validations**:
| ID | Description | Severity |
|----|-------------|----------|
| C002 | FLAG format allowed (not direct issues) | ERROR |
| C006 | Must verify category coverage | WARNING |
| C007 | Must challenge shallow verification | WARNING |
### 1.3 Enhanced Convergence Criteria
**Location**: `src/state/session.ts`
```typescript
const isConverged =
criticalUnresolved === 0 &&
highUnresolved === 0 &&
roundsWithoutNewIssues >= 2 &&
session.currentRound >= 3 &&
allCategoriesExamined &&
issuesStabilized &&
hasEdgeCaseCoverage && // NEW
hasNegativeAssertions; // NEW
```
### 1.4 Re-verification Phase
**Location**: `src/tools/index.ts`
**New Tool**: `elenchus_start_reverification`
- Links to previous verification session
- Focuses on resolved issues
- Generates focused requirements
### 1.5 Critic FLAG System
**Location**: `src/roles/definitions.ts`
Critic can now flag potential issues for Verifier:
```
"⚠️ FLAG FOR VERIFIER: [description]"
```
- Not treated as direct issue raising
- Verifier must address in next round

## 2. Pending Implementations
### 2.1 Programmer Perspective Edge Cases
**Status**: Research Required
Current edge cases are code-centric:
- null/undefined
- Empty arrays
- Boundary values
- Error paths
**Missing perspectives**:
- User behavior edge cases
- Business logic edge cases
- External dependency edge cases
- Data state edge cases
- Operational environment edge cases
- Scale edge cases
**Research Topics**:
1. Common failure patterns in production systems
2. OWASP testing guidelines for edge cases
3. Chaos engineering principles
4. Industry-standard verification checklists
5. Real-world incident post-mortems
### 2.2 Automatic Impact Analysis
**Status**: Design Required
**Current Problem**:
- `elenchus_ripple_effect` is passive (manual call)
- Mediator has dependency graph but doesn't proactively use it
- Token waste from redundant analysis
**Required Changes**:
1. Auto-attach impact analysis when issue is raised
2. Include in Issue object:
```typescript
interface Issue {
// ... existing fields
impactAnalysis?: {
callers: string[]; // Files that call this code
dependencies: string[]; // Files this code depends on
relatedTests: string[]; // Tests that cover this code
affectedFunctions: string[];
};
}
```
3. Convergence check: all impacted code reviewed
### 2.3 Proactive Mediator
**Status**: Design Required
**Current**: Mediator responds to requests
**Required**: Mediator proactively provides context
Changes needed:
1. On issue discovery → auto-provide impact analysis
2. On convergence check → validate impact coverage
3. On round start → provide relevant context summary

## 5. Research Tasks (TODO)
### 5.1 Edge Case Research
- [ ] Survey: Production incident patterns (Netflix, Google, Amazon post-mortems)
- [ ] OWASP Testing Guide - edge case categories
- [ ] IEEE/ACM papers on verification completeness
- [ ] Chaos engineering practices (Gremlin, Chaos Monkey)
- [ ] Security testing edge cases (SANS, NIST)
### 5.2 Impact Analysis Research
- [ ] Static analysis tools (how they track dependencies)
- [ ] IDE "Find Usages" implementation patterns
- [ ] Call graph analysis algorithms
- [ ] Test coverage mapping techniques
### 5.3 Verification Completeness Research
- [ ] Formal verification criteria
- [ ] Code review checklist standards
- [ ] Software quality metrics (cyclomatic complexity, etc.)

## 6. Key Decisions Made
1. **Issue Lifecycle**: Issues can transition through states (MERGED, SPLIT, DISMISSED) during debate
2. **Critic FLAG System**: Critic can flag potential issues without directly raising them, preserving role separation
3. **Exhaustive Coverage**: Verifier MUST cover all 5 categories with ERROR-level enforcement
4. **Edge Case Mandate**: Convergence requires documented edge case analysis
5. **Negative Assertions**: Must state what was verified as clean, not just what's broken
6. **Issue Stabilization**: Convergence requires no recent issue transitions
---
## 7. Next Steps
1. **Research Phase**:
- Edge case categorization from programmer perspective
- Side effect analysis best practices
- Industry verification standards
2. **Implementation Phase**:
- Proactive Mediator with auto-impact analysis
- Programmer-perspective edge case checklist
- Impact coverage in convergence
3. **Testing Phase**:
- Test with real codebase
- Validate convergence criteria
- Measure token efficiency
