Level 4 and 5 autonomy is continuing work inside a written mandate, for boards and operators who delegate, so that a separate runtime checks every action before it happens.
Agents complete more tasks, yet repeated runs still fail and people tend to follow a confident suggestion. That is why a board's mandate, checked by a runtime the model cannot talk past, decides each action, and people keep the decisions they reserved.
A continuing operation cannot depend on a single conversation.
A worker stops after a request may already have reached another system. Its successor must retain what was authorized, what happened and what is still uncertain. Naevum gives continuing work an explicit structure around those facts.
Declare a continuing purpose
Manna represents an organism through a genome and specialized cells. Each pipeline has an intent, resource/capability envelope, flow and heartbeat.
Starts with
An objective and the owner’s permitted domain.
Produces
Supervised units of work with named contracts.
Admit the effect at runtime
Pure transformations and actuation are different operations. An action crosses a gate that checks liveness, laws, policy, provenance, approval tier and capability bounds.
Starts with
A proposed effect and its current operating state.
Produces
An admitted action or recorded refusal.
Condition
Model output supplies no independent actuation authority.
Continue from the causal record
Journals preserve state transitions, effects and unresolved obligations. Recovery examines the existing identity rather than treating lost acknowledgment as permission to repeat.
Starts with
The verified record and current observations.
Produces
A continuation or an explicit recovery decision.
Level 4 defines a domain. Level 5 defines a wider research horizon.
The levels borrow the structure of SAE J3016, the automated-driving scale: Level 4 operates inside a declared domain, Level 5 beyond it. They describe the scope of responsibility the architecture is built for, not a certification.
Level 4: a declared operating domain
The mandate defines tools, conditions, budgets, permitted effects and intervention points. Continuing operation is qualified within that domain.
Context
A known environment and bounded responsibility.
Experience
Persistent work with a specified exception and recovery path.
Level 5: broader adaptation
The research program studies how a system can respond across a wider set of conditions while preserving purpose, evidence and authority.
Context
Changed conditions beyond a fixed task script.
Experience
Candidate adaptation with separate acceptance.
Scope
A broader architecture is not a claim of unrestricted deployed autonomy.
Who allowed that action?
The board sets the domain and reserves decisions; a separate runtime checks every proposal against it. Illustrative.
1 of 4The board approves a mandate for Plant 2: tools, budgets, conditions and which effects need a named person.Decision: The board sets the operating domain.
2 of 4The model proposes a schedule change; the proposal carries no authority of its own.
3 of 4A separate runtime checks the proposal against the mandate, lets it run and records who allowed it and why.
4 of 4Later, a board member asks who allowed the change, and the record names the mandate clause and the check.

1 of 4A supplier asks for a price change outside the mandate's limits.
2 of 4The model proposes accepting it, and the trace leaves the allowed band.
3 of 4The runtime refuses to run it and routes the request to the approver the mandate names.
4 of 4The approver decides, and the refusal and the decision both enter the record.Decision: The named approver accepts or declines the price change.

2 of 4In Naevum's research, the system proposes an adaptation together with the evidence for it.
3 of 4Acceptance stays separate: the runtime holds the adaptation for people to review.
4 of 4The board decides whether to widen the mandate, and until it does, the old limits apply.Decision: The board decides whether to widen the domain.

Where it changes the work.
Illustrative situations, connected to the mechanisms that make them possible.
A project that continues tomorrow
Personal edition
A person has a continuing objective spread across sessions, files and decisions.
How it works
A genome retains the objective and envelope; heartbeats and memory resume work with its earlier context.
What changes
The next session can begin with the objective, prior decisions and outstanding approvals already connected.
Operate an automated multi-market fund
Naevum’s own fund
Market conditions keep changing after any one decision is made.
How it works
A continuing mandate connects observation, constrained action and subsequent evidence.
What changes
The operating system can be examined across a sequence of decisions rather than a single recommendation.
Continue after a worker disappears
Engineering teams
A development attempt ends before the work is resolved.
How it works
The source-bound handover retains objective, checks, findings and the next decision.
What changes
Another attempt can continue from the durable record rather than relying on a departed session.

Supervision keeps failure local and recovery explicit.
The runtime structure assigns failure, cancellation and compensation to the unit that owns the work.
Heartbeat supervision
A pipeline’s heartbeat bounds liveness. A canceled execution cannot acquire a new admitted effect merely because the underlying model is still producing text.
Evidence-bearing approvals
The gate distinguishes human approval, notification and bounded automatic action. Provenance, destination and the artifact under review belong to the decision.
Compensation and uncertainty
A partially completed workflow may require compensation. An external effect already sent cannot be undone by rewinding the local journal.
Outstanding obligations
A lost organ’s work remains named. A successor does not silently inherit an expanded mandate or erase an unresolved approval.
A successor must retain more than a copy of memory.
Manna’s opt-in continuity and lifecycle research implementations are not active by default. They examine causal ancestry, required carryover and policy behavior, and give organ growth a separate, constrained lifecycle.
Functional continuity
A valid causal chain and critical carryover are requirements, not qualities that a high score elsewhere can compensate for. Behavioral probes and capability self-description add separate checks.
Input
Predecessor record, restored components and fixed probes.
Output
A functional continuation judgment or a separately gated descendant.
This is an engineering convention for functional continuity, not a claim about conscious identity.
Finite organ growth
A new organ comes from a reviewed template. Grant reservation, persisted identity and activation are journalled separately so interrupted birth can be reconciled.
Input
Reviewed template digest and available resource ceiling.
Output
An identified allocation with a finite lifetime.
Verified restoration
A rollback certificate names the state that restoration must reproduce. The executor applies the inverse and checks the resulting state digest.
Input
A target state and permitted inverse operation.
Output
A verified restoration or an unresolved recovery requirement.
Irreversible external consequences require compensation, not fictional reversal.
A continuing system returns to what happened.
The assurance design keeps structural validity, policy, artifact checks and observed outcomes as four separate judgments.
A forecast names a target, horizon, population, calibration basis and expiry. An action names its grant and effect identity. Comparing the later outcome changes the evidence available for future work; it does not rewrite the authority that admitted the past action.
Manna supplies Personal and Industrial editions around different responsibilities. Naevum’s own Anemone fund supplies an owner-reported setting for continuing multi-market operation. Black Box applies the same responsibility question to software delivery. Their domains, activation profiles and acceptance evidence remain specific to the system.
Specifications and interfaces.
Inputs, retained state, outputs and limits of Naevum’s Autonomy levels 4 & 5 architecture.
Pipeline contract
Intent + envelope + flow + heartbeat define the supervised work unit. Cells retain specialized state; genome laws remain sealed outside model-generated proposals.
External values retain their untrusted origin. Transformation does not make them eligible to rewrite the intent, topology, envelope or gate conditions.
Effect identity and journal
An admitted effect and its observed result retain causal identity. Uncertainty remains explicit during interruption and recovery.
Four assurance dimensions
Structure, policy, artifact and outcome each carry PASS, FAIL or UNKNOWN with a reason and source. An unevaluated outcome does not inherit a structural pass.
Typed lookahead contract
The world-model research boundary separates SensorReading, BeliefState, Forecast, Grant, Proposal and OutcomeComparison. A forecast carries target, units, horizon, input cutoff and expiry.
Continuity criteria
Causal ancestry and critical carryover act as vetoes. Fixed behavioral probes and self-model fidelity test the successor separately; the scoring conventions require calibration.
Organ resource conservation
Reservation → persisted identity → activation. Retirement checks quiescence, protected templates, obligation transfer and unresolved effects.
Recovery certificate
A target state digest is separate from the action that restores it. Restoration is checked after execution; a ledger entry alone does not establish rollback.
Questions about Autonomy levels 4 & 5.
Can an autonomous system remain under human authority?
Yes. Continuing execution can operate inside a mandate while designated decisions, changes of scope and consequential actions remain with the responsible people.
Manna’s predictive research boundary separates observations, belief, forecast, grant, proposal and outcome comparison. A proposal must name the current objective revision, parent grant and effect identity.
Freshness, scope, endorsed observations and existing uncertainty are rechecked before admission. A forecast can motivate a bounded action; it cannot add capabilities or relabel its sources.
Functional continuity has its own convention
Causal ancestry and critical carryover are hard requirements. Fixed policy probes and accurate capability self-description add functional checks; no accepted scientific measure of conscious continuity is asserted.
The continuity, lifecycle and attention studies are opt-in reference implementations. Their integration, intervention path and recovery acceptance are named in the deployment profile.
