Kinetic Trust Protocol (KTP) - Deprecation and End-of-Life Specification

This document specifies deprecation and end-of-life procedures for the Kinetic Trust Protocol (KTP). All agents end—through version sunset, graceful retirement, emergency termination, or system failure. The Death Edge is the final transition, requiring the same intentionality as Genesis. This specification covers model deprecation, agent retirement, trajectory preservation, knowledge transfer, and the ceremonies that mark endings.

Introduction

Everything ends. Models are superseded. Agents complete their purpose. Systems fail. The Death Edge—the moment of ending—deserves as much attention as the Genesis Edge (beginning) and the Origin Edge (model provenance).

This specification addresses what happens when:

• A model version is deprecated
• An agent is retired
• An agent fails catastrophically
• A zone is dissolved
• The entire KTP system sunsets

Design Principles

Deprecation embodies these principles:

1. Endings Deserve Ceremony: Endings are not just technical events—they have meaning.

2. Trajectory Preservation: What was learned should survive.

3. Clean Transitions: Others depending on the ending entity need orderly handoffs.

4. Graceful Degradation: Forced endings should minimize harm.

5. No Orphans: Dependents must be addressed before ending.

6. Memory Persists: Even after ending, the record remains.

Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 (RFC 2119 and RFC 8174).

Terminology

Deprecation: The process of marking something for eventual removal while maintaining current functionality.

End-of-Life (EOL): The point at which an entity ceases active operation.

Death Edge: The final transition from active to ended state.

Graceful Retirement: Planned, orderly ending with full ceremony.

Emergency Termination: Immediate ending due to security or safety concerns.

Orphan: An entity left without required dependencies (sponsor, zone).

Succession: Transfer of responsibilities to a successor entity.

Trajectory Archive: Preserved record of an ended agent's trajectory.

The Death Edge

Definition

The Death Edge is the moment of transition from existence to non- existence as an active agent. Unlike the Origin Edge (which cannot be fully known) or the Genesis Edge (which can be controlled), the Death Edge can be witnessed and honored.

Death Edge Ceremony

{ "death_edge_ceremony": { "ceremony_id": "DEATH-2025-12-31-001", "agent_id": "agent:independent:3gen:acme:abc123", "ceremony_time": "2025-12-31T00:00:00Z", "ceremony_type": "ending", "participants": { "agent": "present_for_final_moments", "sponsor": "sponsor:alice.smith", "successor": "agent:independent:4gen:acme:def456", "zone": "zone:zone-blue-prod-01" }, "witnesses": [ "witness:zone-blue-prod-01", "witness:federation-council" ], "ceremony_elements": { "acknowledgment": { "description": "Agent's existence and contributions acknowledged", "speaker": "sponsor", "completed": true }, "gratitude": { "description": "Thanks expressed for agent's service", "participants": "all", "completed": true }, "legacy_statement": { "description": "What agent leaves behind", "content": "4721 successful operations, 3 relationships maintained, knowledge base contributed", "completed": true }, "release": { "description": "Formal release from obligations", "released_by": "sponsor", "completed": true }, "final_words": { "description": "Agent's final communication", "content": "Thank you for the opportunity to serve.

Zone Dissolution

Dissolution Process

When an entire zone ends:

Phase 1: ANNOUNCEMENT (90+ days before)

• Dissolution scheduled
• All agents notified
• Migration paths identified
• Federation notified

Phase 2: MIGRATION (dissolution - 60 days)

• Agents migrate to other zones
• Trust transfers arranged
• Orphan agents addressed

Phase 3: FINAL OPERATIONS (dissolution - 7 days)

• Only migration operations
• New operations blocked
• Final agent migrations

Phase 4: DISSOLUTION (dissolution day)

• Remaining agents retired
• Zone ceremony performed
• Archives transferred
• Zone ended

Phase 5: PRESERVATION (post-dissolution)

• Archives maintained by federation
• Access policies transferred
• Memorial record created

Zone Dissolution Record

{ "zone_dissolution": { "zone_id": "zone-blue-prod-01", "dissolution_date": "2025-12-31T00:00:00Z", "reason": "organization_shutdown", "final_statistics": { "total_agents_ever": 4721, "agents_migrated": 4689, "agents_retired": 32, "total_transactions": 47213847, "zone_age_days": 365 }, "migrations": { "destination_zones": [ "zone-blue-prod-02", "zone-cyan-prod-01" ], "migration_success_rate": 0.993 }, "archive_transfer": { "destination": "federation-archive:global", "data_transferred": true, "integrity_verified": true }, "ceremony": { "type": "zone_ending", "witnesses": ["federation-council"], "performed": true } } }

Security Considerations

Secure Deletion

Some data must be securely deleted:

• Cryptographic keys destroyed
• Secrets purged
• No recovery possible

Zombie Prevention

Prevent "zombie" agents (ended but still operating):

• Immediate Trust Proof revocation
• Network access termination
• Key rotation at zone level
• Monitoring for resurrection attempts

Archive Security

Archives must be protected:

• Encryption at rest
• Access logging
• Integrity verification
• Authorized access only

IANA Considerations

This document has no IANA actions.
