Surface Validity Contract
Authority: AC-1 (S. Jason Prohaska)
Classification: T5-RIGID | ENTERPRISE-FINAL
Mode: FAIL-CLOSED · NO PLACEHOLDERS · EVIDENCE REQUIRED
Version: 3.0
Canonical Timestamp: 2026-02-05T18:10:00+01:00
Purpose
This module defines the validity contract that all ETHRAEON surfaces must satisfy. A surface that does not meet these requirements is classified as INVALID and must be remediated.
Mandatory Surface Attributes
Every surface MUST declare the following attributes:
| Attribute | Type | Description |
| `surface_name` | string | Canonical name identifier |
| `fqdn` | string | Fully qualified domain name |
| `class` | enum | Surface class (see Module 04) |
| `lifecycle` | enum | Lifecycle state (see Module 05) |
| `served_by` | string | Origin server/service identifier |
| `expected_status` | array[int] | Expected HTTP status codes |
| `monitoring` | enum | Monitoring state (enabled/disabled) |
| `intent` | string | Purpose description |
Conditional Attributes
The following attributes are required based on surface configuration:
| Condition | Required Attribute | Type |
| `immutable = true` | `canonical_hash` | string (SHA-256) |
| `lifecycle = HOLD` | `hold_reason` | string |
| `lifecycle = HOLD` | `hold_page_deployed` | boolean |
| `lifecycle = RETIRED` | `retirement_date` | ISO-8601 |
| `lifecycle = RETIRED` | `archive_confirmed` | boolean |
| `class = STAKEHOLDER` | `access_control` | object |
| `class = OPERATOR` | `authentication` | object |
Validity Rules
4.1 Core Validity Rules
| ID | Rule | Enforcement |
| VR-01 | All mandatory attributes present | FAIL if missing |
| VR-02 | Class is valid enum value | FAIL if invalid |
| VR-03 | Lifecycle is valid enum value | FAIL if invalid |
| VR-04 | expected_status is non-empty array | FAIL if empty |
| VR-05 | FQDN is syntactically valid | FAIL if malformed |
| VR-06 | Intent is non-empty string | FAIL if empty |
4.2 State-Dependent Rules
| ID | Rule | Enforcement |
| VR-10 | ACTIVE surfaces have monitoring enabled | FAIL if disabled |
| VR-11 | HOLD surfaces have hold_page_deployed | FAIL if missing |
| VR-12 | RETIRED surfaces have archive_confirmed | FAIL if missing |
| VR-13 | Immutable surfaces have canonical_hash | FAIL if missing |
4.3 Cross-Reference Rules
| ID | Rule | Enforcement |
| VR-20 | Class RETIRED requires lifecycle RETIRED | FAIL if mismatch |
| VR-21 | OPERATOR class requires authentication | FAIL if missing |
| VR-22 | STAKEHOLDER class requires access_control | FAIL if missing |
