AI agent retirement and evidence preservation

A bilingual protocol that separates shutdown, evidence preservation, data disposition, dependency handoff and closure review. The goal is not to make a system disappear, but to show that acting authority is closed, required records remain inspectable and residual duties have named owners.

Core principle

Stopping service is not completed retirement.

A defensible retirement must answer whether the system can still act, which dependencies are affected, what evidence must be preserved, what data should be disposed of, what a successor inherited and who owns each residual.

Applicability boundaryThis is a public engineering and review method—not legal advice, a records-retention schedule, litigation-hold instruction, privacy determination, digital-forensics procedure, media-sanitisation implementation standard, audit or certification. Real disposition requires an organisation to select the applicable process for its assets, jurisdictions, contracts, incidents and safety duties.

Separate four responsibilities

Revocation, preservation, disposition and closure review must remain mutually inspectable.

01
retirement owner
Own scope, sequence, exceptions and the final closure decision.
02
system custodian
Revoke authority, map dependencies and verify that the acting system cannot return silently.
03
evidence and data custodian
Separate justified preservation from disposal, record access and protect provenance.
04
independent closer
Challenge completeness, successor claims, residual access and closure evidence.

Eight retirement gates

Each gate requires a question, an evidence set and an explicit blocking condition.

Freeze the retirement object and reason

Core question: Which exact agent, model, tools, memory, release, environment and authority are being retired—and why now?
Evidence to preserve: Stable system identity, decision owner, reason, effective window, affected cohorts, exclusions and linked incident or change records.
Blocking condition: Do not retire an ambiguous product label while versions or delegated agents remain unidentified.

Map dependencies, obligations and successor paths

Core question: Who and what still depends on this system, its outputs, identifiers, interfaces, schedules or records?
Evidence to preserve: Dependency graph, owners, downstream uses, automated jobs, service commitments, unresolved appeals and successor mapping.
Blocking condition: Block shutdown when consequential users have no safe fallback or an unowned dependency can still act.

Revoke authority and stop new work

Core question: Can credentials, tools, queues, triggers, network routes, write paths and delegated authority be disabled in a tested order?
Evidence to preserve: Revocation plan, denied-action tests, credential inventory, scheduler state, human takeover, rollback and emergency exception log.
Blocking condition: Retirement is not complete while the system can accept work, recover credentials or trigger external action.

Separate evidence preservation from data disposal

Core question: Which records must remain inspectable, which data should be returned or deleted, and what purpose and boundary support each choice?
Evidence to preserve: Record classes, purpose, owner, access, retention horizon, legal or contractual escalation flag, redaction, deletion hold and known gaps.
Blocking condition: Do not erase review evidence or retain unrelated sensitive data merely because the system is closing.

Dispose of models, data, secrets and media by class

Core question: What action—archive, return, revoke, clear, purge, destroy or preserve—applies to each asset and storage location?
Evidence to preserve: Asset and location inventory, sensitivity class, selected method, authority, execution evidence, exceptions and validation result.
Blocking condition: Do not treat file deletion, account closure or a provider promise as verified sanitisation.

Transfer only bounded continuity

Core question: Which tasks, records and responsibilities move to a successor, and which capabilities must not be inherited?
Evidence to preserve: Successor identity, accepted scope, provenance links, migration tests, rejected items, user communication, rollback and acceptance owner.
Blocking condition: A successor must not inherit old authority, memory or unresolved risk by default.

Verify absence, preservation and residual exposure

Core question: Can an independent reviewer show that action paths are closed, required evidence remains readable and residual copies or dependencies are known?
Evidence to preserve: Negative action tests, access-denial evidence, archive restore test, sanitisation validation, residual inventory, exceptions and reviewer dissent.
Blocking condition: Do not close when authority can reappear, required records cannot be restored or material residuals are unowned.

Issue an expiring closure decision

Core question: What is closed, what remains, who owns residual duties, when is the next review and what reopens the record?
Evidence to preserve: Closure state, evidence index, residuals, owners, exceptions, successor limits, review date, expiry and reopen triggers.
Blocking condition: An ownerless, evidence-free or exception-blind closure is an unverified claim, not a completed retirement.

Closure states

Replace “switched off” with a verifiable, expiring state.

These are states in FUURAA’s public method, not international retirement levels. A state must bind the exact system, evidence index, residual duties, owner and review date.

State	Minimum meaning
retirement planned	Scope is frozen, but authority or dependencies remain active.
authority closed, evidence open	No new action is allowed; preservation, disposal or review remains incomplete.
closed with residual duties	Action paths are closed; named owners retain bounded archives, exceptions or successor duties.
closure expired or reopened	A residual, access path, new claim or missed review invalidates reliance on closure.

Fifteen fields make a closure reconstructable and reopenable.

03dependency and affected-party map
Record an inspectable identifier, scope, evidence path, execution result, owner or explicit unknown.
04authority-revocation evidence
Record an inspectable identifier, scope, evidence path, execution result, owner or explicit unknown.
05preservation classes and purposes

09migration and negative-action tests
Record an inspectable identifier, scope, evidence path, execution result, owner or explicit unknown.
10archive readability test

14closure state and rationale
Record an inspectable identifier, scope, evidence path, execution result, owner or explicit unknown.
15expiry, next review and reopen triggers
Record an inspectable identifier, scope, evidence path, execution result, owner or explicit unknown.

FUURAA analysisRetiring an AI agent is more than closing an interface: acting capability can persist in tokens, scheduled jobs, delegated agents, caches, memory, downstream copies and successor systems. High-quality closure therefore proves two apparently opposing conditions together—the authority and data that should not persist are no longer usable, while the evidence that must persist remains readable, locatable and purpose-bound. Failure on either side means retirement should not be declared complete.
