Classification: T5-RIGID | ENTERPRISE-FINAL

Purpose
This module defines the incident classification taxonomy for the ETHRAEON system. All incidents must be categorized according to this taxonomy for consistent tracking, response, and analysis.
Incident Types
2.1 Canonical Incident Types
| Type | Code | Description |
| Availability | `availability` | Service or surface unavailable |
| Integrity | `integrity` | Data or content integrity violation |
| Auth Expected | `auth_expected` | Authentication/authorization failure |
| Configuration | `configuration` | Configuration error or inconsistency |
| Edge Cache | `edge_cache` | CDN/edge cache mismatch or failure |
2.2 Type Definitions
#### Availability Incidents
Triggered when:
- Surface returns non-expected HTTP status
- Service health check fails
- Response timeout exceeded
- DNS resolution failure
#### Integrity Incidents
Triggered when:
- Hash mismatch detected
- Immutability violation
- Unauthorized content modification
- Data corruption detected
#### Auth Expected Incidents
Triggered when:
- Valid credentials rejected
- Session unexpectedly terminated
- Permission denied incorrectly
- Authentication service failure
#### Configuration Incidents
Triggered when:
- Invalid configuration detected
- Configuration drift from canon
- Missing required configuration
- Conflicting configuration values
#### Edge Cache Incidents
Triggered when:
- Edge/origin content mismatch
- Cache purge failure
- Unexpected cache behavior
- SSL/TLS certificate mismatch
Severity Levels
3.1 Severity Definitions
| Level | Code | Response Time | Description |
| Critical | `CRITICAL` | Immediate | System-wide impact, data at risk |
| High | `HIGH` | < 1 hour | Major feature impacted |
| Medium | `MEDIUM` | < 4 hours | Limited impact, workaround available |
| Low | `LOW` | < 24 hours | Minor impact, no urgency |
3.2 Severity Matrix
| Incident Type | Production Impact | Data Risk | Severity |
| Availability | PRIMARY surface | Any | CRITICAL |
| Availability | OPERATOR surface | Any | HIGH |
| Availability | Other surfaces | Any | MEDIUM |
| Integrity | Any | Yes | CRITICAL |
| Integrity | Any | No | HIGH |
| Auth Expected | Production | Any | HIGH |
| Auth Expected | Non-production | Any | MEDIUM |
| Configuration | Production | Any | HIGH |
| Configuration | Non-production | Any | LOW |
| Edge Cache | Persistent mismatch | Any | CRITICAL |
| Edge Cache | Transient mismatch | Any | MEDIUM |
