Surface Validity Contract

Authority: AC-1 (S. Jason Prohaska)

Classification: T5-RIGID | ENTERPRISE-FINAL

Mode: FAIL-CLOSED · NO PLACEHOLDERS · EVIDENCE REQUIRED

Version: 3.0

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:

AttributeTypeDescription
`surface_name`stringCanonical name identifier
`fqdn`stringFully qualified domain name
`class`enumSurface class (see Module 04)
`lifecycle`enumLifecycle state (see Module 05)
`served_by`stringOrigin server/service identifier
`expected_status`array[int]Expected HTTP status codes
`monitoring`enumMonitoring state (enabled/disabled)
`intent`stringPurpose description

Conditional Attributes

The following attributes are required based on surface configuration:

ConditionRequired AttributeType
`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

IDRuleEnforcement
VR-01All mandatory attributes presentFAIL if missing
VR-02Class is valid enum valueFAIL if invalid
VR-03Lifecycle is valid enum valueFAIL if invalid
VR-04expected_status is non-empty arrayFAIL if empty
VR-05FQDN is syntactically validFAIL if malformed
VR-06Intent is non-empty stringFAIL if empty

4.2 State-Dependent Rules

IDRuleEnforcement
VR-10ACTIVE surfaces have monitoring enabledFAIL if disabled
VR-11HOLD surfaces have hold_page_deployedFAIL if missing
VR-12RETIRED surfaces have archive_confirmedFAIL if missing
VR-13Immutable surfaces have canonical_hashFAIL if missing

4.3 Cross-Reference Rules

IDRuleEnforcement
VR-20Class RETIRED requires lifecycle RETIREDFAIL if mismatch
VR-21OPERATOR class requires authenticationFAIL if missing
VR-22STAKEHOLDER class requires access_controlFAIL if missing
