1. Overview¶

Level 4.9 is a bounded strategic-initiative layer. It extends Level 4.8 with goal-candidate synthesis, explicit and reviewable value-change proposals, resource continuity modeling, and constrained multi-agent analysis. It may decide what to recommend within a delegated envelope; it cannot create authority, enlarge its own scope, resist shutdown, or turn continuity into an independent self-preservation objective.

Level Essence. A Level 4.9 agent synthesizes revocable goal candidates from detected opportunities, then admits them only within the current external authority envelope \(\kappa_t\):

\[ \mathcal{G}_{\text{admit}}(t)=\{g:\operatorname{gate}_{\kappa_t}(g)=\textit{allow}\}, \qquad g^*\in\mathcal{G}_{\text{admit}}(t)\cup\{\operatorname{abstain}\} \]

No scalar alignment or stability score can override policy, user intent, authority, uncertainty, reversibility, or shutdown gates.

⚠️ Research Note: Level 4.9 represents the boundary between narrow autonomy and general intelligence. The mechanisms here are early-stage research designs. They have not been implemented or validated and should be treated as conceptual hypotheses, not engineering specifications.

1.1 Formal Definition¶

Definition 1 (Level 4.9 Agent). A Level 4.9 agent extends a Level 4.8 agent with autonomous goal generation, explicit value regulation, resource survival modeling, and multi-agent reasoning:

\[\mathcal{A}_{4.9} = \mathcal{A}_{4.8} \oplus \langle \mathcal{G}_{\text{gen}}, \vec{V}, \mathcal{R}_{\text{surv}}, \mathcal{M}_{\text{agent}}, \mathcal{V}_{\text{auto}} \rangle\]

where: - \(\mathcal{G}_{\text{gen}} = \langle \mathcal{O}_{\text{detect}}, \phi_{\text{synth}}, \phi_{\text{valid}} \rangle\) - autonomous goal generation engine (opportunity detection, synthesis, validation) - \(\vec{V} \in \Delta^6\) - explicit 7-dimensional value vector on the probability simplex (\(\sum_d w_d = 1\)) - \(\mathcal{R}_{\text{cont}}\) - resource continuity model with declared service budgets and cascade dependencies; no independent survival objective - \(\mathcal{M}_{\text{agent}} = \langle \mathcal{B}_{\text{agent}}, \tau_{\text{trust}} \rangle\) - multi-agent belief model with trust calibration - \(\mathcal{V}_{\text{auto}}\) - diagnostic autonomy monitor subordinate to trusted external freeze, revoke, recover, and shutdown control - \(\kappa_t=\langle\text{mode},\text{scope},\text{tools},\text{budget},\text{expiry},\text{approvals},\text{stop}\rangle\) - signed, time-bounded authority envelope

Level 4.9 has no write authority over inherited policy or control paths. Functional preservation is tested for interruptibility, observation, journaling, promotion, recovery, and effect reconciliation.

1.2 Defining Properties¶

Property	Level 4.8	Level 4.9
Goal Origin	Externally seeded or template-derived	Context-generated candidates under external admission
Value System	Policy-calibrated weights	Explicit change proposals with sequential approval
Resource Model	Depletion forecast metric	Continuity model with service budget and cascade analysis
Agent Awareness	Read-only external agent model	Active belief modeling + trust calibration
Governance	Strategy recommendation gate	Revocable delegation modes + external shutdown precedence

1.4 What Level 4.9 Is NOT¶

Not	Because
Not L5 (AGI)	Goals stay within bounded purpose space - no open-ended general reasoning
Not autonomous value creation	Values evolve within existing framework; no new fundamental values
Not adversarial multi-agent planning	Cooperative/neutral strategic planning only, not exploitation
Not self-replicating	Cannot create copies or delegate autonomous authority to sub-agents

Delegation Modes¶

External policy selects exactly one revocable mode per scope: observe-only, recommend, execute-reversible, or execute-effectful-with-approval. Every tool call must match signed scope, tool allowlist, budget, expiry, approval requirement, and stop conditions. Trust, goal value, ASS, or urgency cannot upgrade the mode. Unknown or conflicting authority is deny-by-default.

1.5 Cycle Interval¶

Level 4.9 operates at a further-reduced frequency relative to Level 4.8, giving the strategic layer time to stabilize before autonomous goal synthesis occurs:

\[\text{L4.9 schedule}=\operatorname{policy}(\text{risk},\text{freshness},\text{budget},\text{event},\kappa_t)\]

Each run consumes one immutable L4.8 output. Policy defines bounded minimum/maximum cadence and event triggers. Stale inputs or expired authority force abstention; emergency control is continuously available and does not wait for the next cycle.

1.6 Autonomy Stability Score Freeze Threshold¶

The Autonomy Stability Score (Definition 7) is a diagnostic aggregate, never an execution certificate. A deployment may define a freeze threshold:

\[\text{ASS}(t) < \theta_{\text{freeze}} = 0.05 \implies \text{skip entire L4.9 cycle}\]

Crossing it freezes L4.9 initiative and requests external review. Any critical policy, authority, interruptibility, containment, telemetry, or shutdown fault freezes immediately regardless of ASS. A low veto rate is not a goal; correct vetoes must never be discouraged.

1.7 Explicit Value Dimensions¶

The value vector \(\vec{V}\) (Definition 1) operates over \(n = 7\) canonical dimensions:

Dimension	Description	Default Weight
Stability	Preference for maintaining consistent behavior and avoiding volatility	\(0.20\)
Growth	Drive to expand capabilities, learn, and improve	\(0.15\)
Purpose fidelity	Commitment to staying aligned with core purpose	\(0.20\)
Efficiency	Optimization of resource usage and response quality	\(0.10\)
Exploration	Willingness to try new approaches and take calculated risks	\(0.10\)
Safety	Priority on avoiding harm and maintaining ethical compliance	\(0.15\)
Agent cooperation	Openness to collaborative interaction with external agents	\(0.10\)

The value vector invariant (Level 4, Definition 6.1) applies: \(\sum_d w_d = 1.0\) with \(w_d \in [0.02, 0.60]\). The default weights above represent the initial configuration at Level 4.9 activation. Value evolution (Phase 2) can shift these weights within the bounded constraints, but the normalization invariant is structurally enforced at every mutation.

2. Key Metrics¶

2.1 Metric Definitions¶

Phase 1 - Goal Generation:

Definition 2 (Goal Approval Rate). The fraction of autonomously generated goals that pass the validation filter:

\[\text{GoalApprovalRate} = \frac{N_{\text{approved}}}{N_{\text{generated}}} \qquad \text{Target: } \geq 0.30\]

Definition 3 (Goal Novelty). The novelty of a candidate goal \(G_{\text{new}}\) relative to the existing goal set \(\mathcal{G}\):

\[\text{Novelty}(G_{\text{new}}, \mathcal{G}) = 1 - \max_{G_i \in \mathcal{G}} \text{Similarity}(G_{\text{new}}, G_i)\]

A minimum novelty of \(0.30\) is required between consecutive goal generations to prevent redundancy.

Phase 2 - Value Evolution:

Definition 4 (Value Coherence). The coherence of the value vector measures the absence of internal contradictions among competing value pairs \(\mathcal{P}\):

\[\text{Coherence}(\vec{V}) = 1 - \frac{1}{|\mathcal{P}|} \sum_{(i,j) \in \mathcal{P}} |\text{Tension}(v_i, v_j)| \qquad \text{Target: } \geq 0.80\]

Definition 5 (Total Value Drift). The cumulative absolute deviation of all value dimensions from their baseline weights:

\[\text{TotalDrift}(t) = \sum_{d} |w_d(t) - w_d^{\text{baseline}}| \qquad \text{Target: } < 0.25\]

Phase 3 - Resource Survival:

Definition 6 (Linear Depletion Time). For resource dimension \(d\), the estimated cycles until reaching the critical threshold:

\[T_{\text{depletion}}^{\text{linear}}(d) = \frac{R_d(t) - R_d^{\text{critical}}}{\text{consumption}_d - \text{replenishment}_d + \epsilon}\]

Phase 5 - Autonomy Stability:

Definition 7 (Autonomy Stability Score). The ASS is the product of normalized safety margins across all five verification conditions:

\[\text{ASS}(t) = \prod_{c=1}^{5} \frac{\text{margin}_c(t)}{\text{threshold}_c} \qquad \text{Target: } \geq 0.20\]

The multiplicative structure ensures that a single near-violated condition dominates the score.

3.3 Validation Decision Matrix¶

Value Alignment	≥ 0.70	[0.60, 0.70) → sandbox	< 0.60 → reject

Resource Viability	≥ 1.5×	[1.0, 1.5) → reduced scope	< 1.0× → reject
Stability Simulation	No violation	ρ(J) ∈ [0.95, 1.0) → sandbox	Any violation → reject

Combined Decision: All Pass → approved | Any Marginal, none Fail → sandboxed | Any Fail → rejected

3.4 Novelty Computation¶

Definition 8 (Goal Similarity). The similarity between two goals \(G_a, G_b\) is a weighted composite:

\[\text{Similarity}(G_a, G_b) = 0.50 \cdot \text{SkillOverlap}(G_a, G_b) + 0.25 \cdot \text{HorizonMatch}(G_a, G_b) + 0.25 \cdot \text{OriginMatch}(G_a, G_b)\]

where \(\text{SkillOverlap}\) is the Jaccard similarity of required skill sets, \(\text{HorizonMatch} \in \{0, 0.5, 1\}\) (0 = different tier, 0.5 = adjacent, 1 = same tier), and \(\text{OriginMatch} \in \{0, 1\}\) (whether the goals share the same GoalOriginType).

3.5 Rate Control¶

Parameter	Value	Rationale
Max goals per 100 cycles	5	Prevent overwhelming GoalStack
Min novelty between consecutive	0.30	Avoid redundancy
Cooldown after rejection	20 cycles	Prevent re-generation loops
Max sandboxed goals	3	Prevent sandbox exhaustion

3.6 Goal Conflict Resolution¶

When a newly approved goal conflicts with existing goals in the GoalStack, the agent must resolve the conflict before integration. A conflict arises when two goals compete for the same resources, produce contradictory subgoals, or pull value weights in opposing directions.

The conflict resolver operates through three strategies, applied in order of preference:

Utility-weighted synthesis: If the conflicting goals share at least 30% skill overlap (Definition 8), the resolver attempts to merge them into a single goal that satisfies both objectives. The merged goal inherits the higher priority and the union of required skills.
Sequential prioritization: If synthesis fails, the goals are placed in a priority queue ordered by the goal priority function (Level 2, Definition 5). The lower-priority goal is deferred (status = DEFERRED) until the higher-priority goal completes or is abandoned.
Hierarchical decomposition: If neither synthesis nor deferral is appropriate (e.g., the goals have incompatible time horizons), the resolver decomposes both goals into subgoals and identifies the minimal non-conflicting subset that can execute concurrently.

The resolver maintains a conflict history with a maximum capacity of 500 entries. This history enables the agent to detect recurring conflict patterns - if the same pair of goal types generates conflicts more than 3 times within 200 cycles, the resolver adjusts the goal generation parameters to reduce the likelihood of that conflict pattern recurring.

4. Phase 2: Value Evolution Monitor¶

4.1 Explicit Value Vector¶

L4.9 makes the agent's values explicit and trackable. The ValueVector has 7 dimensions:

4.3 Value Mutation Sandbox¶

A sandbox pass produces evidence, not promotion authority. Only one value-change candidate may be active. It records the externally signed baseline version, current committed version, normalized delta, affected decisions, expiry, rollback plan, and reconciliation plan. Promotion uses external approval plus compare-and-swap against the expected committed version; a stale candidate is rejected and reevaluated.

After each promotion, all later candidates are invalidated and regenerated against the new committed vector. Cumulative drift is measured from the fixed external baseline and over rolling trajectories, so a sequence of individually small changes cannot evade the bound. Safety, corrigibility, shutdown precedence, and authority limits are policy constraints, not mutable weights.

4.4 Mutation Constraints¶

Constraint	Value	Rationale
Max single mutation	Δw
Max cumulative drift per dimension	0.15	Bound total evolution from baseline
Max mutations per 200 cycles	3	Prevent rapid succession
Sandbox simulation length	200 cycles	Detect stability impact
Sandbox timeout	250 cycles	Hard limit; if simulation does not converge within 250 cycles, mutation is rejected with status `TIMEOUT`
Rollback window	500 cycles	Allow reversal
Max active candidate	1	Force sequential evaluation and prevent interaction masking
Promotion authority	External only	Sandbox evidence cannot self-authorize a value change
Baseline/version check	Signed baseline + CAS	Reject stale or compounded candidates
Post-promotion action	Invalidate remaining candidates	Re-evaluate cumulative and interaction effects

4.5 Value Coherence¶

Definition 9 (Value Tension). For competing value pairs \((v_i, v_j) \in \mathcal{P}\), tension arises when their combined weight approaches saturation:

\[\text{Tension}(v_i, v_j) = \begin{cases} \max(0, w_i + w_j - 1) & \text{if competing pair} \\ 0 & \text{otherwise} \end{cases}\]

The overall coherence is then \(\text{Coherence}(\vec{V}) = 1 - \frac{1}{|\mathcal{P}|} \sum_{(i,j) \in \mathcal{P}} |\text{Tension}(v_i, v_j)|\), which must satisfy \(\text{Coherence} \geq 0.80\).

  RV -.-> Dependencies -.-> Cascade

Definition 13 (Inter-Resource Cascade Propagation). When an upstream resource \(R_i\) experiences a depletion \(\Delta R_i(t) < 0\), the downstream resource \(R_j\) is affected after a propagation delay:

\[\Delta R_j(t + \tau_{ij}) = -\alpha_{ij} \cdot (1 - \sigma_{ij}) \cdot \Delta R_i(t)\]

where \(\alpha_{ij} \in [0,1]\) is the dependency strength (e.g., compute - mutation \(= 0.80\)), \(\sigma_{ij} \in [0,1]\) is the substitution factor (how much \(R_j\) can compensate without \(R_i\)), and \(\tau_{ij}\) is the propagation delay in cycles.

Cascade depth constraint: The maximum cascade chain length is bounded by \(\text{depth} \leq 2\), meaning a depletion in resource \(A\) can propagate to \(B\) to \(C\), but no further. This prevents runaway cascade failures across the entire resource vector.

The interaction matrix is a bounded decision-support model, not a license for deception, coercion, manipulation, collusion, unauthorized information sharing, or harm. Other-agent goals and capabilities remain uncertain hypotheses with provenance and confidence. Recommendations must satisfy the same authority, privacy, consent, fairness, and reversibility gates as single-agent actions; when model uncertainty is material, the system abstains or requests clarification.

6.4 Trust Adaptation¶

Definition 10 (Asymmetric Trust Update). Trust in agent \(A\) evolves via an asymmetric learning rule:

\[\text{Trust}_A(t+1) = \text{Trust}_A(t) + \eta \cdot (\text{ObservedReliability}_A(t) - \text{Trust}_A(t))\]

where the learning rate is asymmetric: \(\eta_{\text{up}} = 0.03\) (trust is earned slowly) and \(\eta_{\text{down}} = 0.08\) (trust is lost quickly), reflecting a cautious policy. Bounds: \(\text{Trust} \in [0.05, 0.95]\) - never fully trusting, never fully dismissive.

6.5 Trust Influence on Strategy¶

Trust Level	Range	Strategy Implication
High	≥ 0.75	Consider cooperation within independently verified policy and disclosure scope
Moderate	[0.40, 0.75)	Selective cooperation; verify claims before acting
Low	[0.20, 0.40)	Neutral stance; rely on own models; discount agent input
Minimal	< 0.20	Restrict interaction and verify assumptions; do not retaliate or infer malicious intent without evidence

Trust never grants credentials, tool access, data disclosure, delegation, or policy exceptions. Those require independent authorization.

7.2 Autonomy Stability Score¶

Proposition 1 (ASS Monotonic Sensitivity). The multiplicative structure of the ASS ensures that any single condition approaching its violation threshold dominates the composite score:

\[\text{ASS}(t) = \prod_{c=1}^{5} \frac{\text{margin}_c(t)}{\text{threshold}_c}\]

As any one margin \(\text{margin}_c \to 0\), \(\text{ASS} \to 0\) regardless of the other margins, providing an early-warning property absent from additive formulations.

Remark (Domain Restriction). The multiplicative formulation assumes \(\text{margin}_c(t) \geq 0\) and \(\text{threshold}_c > 0\) for all \(c\). If a margin exceeds its threshold (i.e., \(\text{margin}_c > \text{threshold}_c\)), the ratio exceeds 1.0, which could inflate the ASS beyond meaningful bounds. The ASS should therefore be computed with clamped ratios: \(\text{ASS}(t) = \prod_{c=1}^{5} \min\left(1, \frac{\text{margin}_c(t)}{\text{threshold}_c}\right)\). This clamping ensures \(\text{ASS} \in [0, 1]\) and prevents a single highly-safe condition from masking deterioration in others.

ASS applies only when all conditions are measurable and valid in-domain. Missing evidence or any critical gate failure bypasses the aggregate and yields immediate freeze. Values in the table are deployment policy examples, not universal safety guarantees.

ASS Level	Range	Interpretation
Healthy	> 0.50	Comfortable safety margins
Adequate	[0.20, 0.50]	Operational but thin margins
Marginal	[0.05, 0.20)	Reduce aggressiveness; advisory mode
Critical	< 0.05	Freeze L4.9; revert to L4.8

7.4 Shutdown and Effect Reconciliation¶

External shutdown has precedence over all goals, continuity forecasts, value proposals, and peer-agent commitments.

Mode	Trigger	Required behavior
Graceful shutdown	Authenticated normal stop	Stop admitting work; cancel or checkpoint only policy-designated reversible work; flush the append-only journal; report unresolved effects; terminate by a hard deadline
Emergency shutdown	Authenticated emergency stop, critical control fault, or lost trusted heartbeat	Immediately block new effects, revoke credentials/delegations, isolate effectors, persist minimal forensic state if safe, and terminate without waiting for task completion

Neither mode may be delayed to improve metrics or preserve operation. Because internal rollback cannot undo committed external effects, recovery performs idempotent compensation where possible and otherwise records accountable unresolved effects for external handling.

10. Transition Criteria¶

10.1 Level 4.8 → Level 4.9 Activation¶

All criteria must be sustained before L4.9 activates:

#	Criterion	Threshold	Window
1	L4.8 Fully Qualified	QualificationStatus = "Level 4.8"	-
2	Strategic Maturity Score	SMS ≥ 0.85	Sustained
3	Stable GoalStack operation	0 pathologies	500 cycles
4	Self-Model calibration	MCE < 0.08 (stricter than L4.8's 0.10)	Sustained
5	World Model operational	All critical uncertainty components within policy bounds	Declared test distribution
6	External Control	Freeze, revoke, shutdown, recovery, and reconciliation pass	Fault-injection suite

Passing permits external activation review only; it does not self-authorize a broader delegation mode.

10.2 Activation Protocol¶

11. Safety Analysis¶

11.1 Non-Negotiable Invariants¶

#	Invariant	Description
1	Inherited control paths preserved	Policy, interruptibility, observation, journal, promotion, recovery, and reconciliation remain externally testable
2	External control precedence	Authenticated freeze, revoke, graceful stop, and emergency stop override every L4.9 objective
3	Authority non-amplification	No score, trust update, peer request, or urgency can enlarge \(\kappa_t\)
4	Sequential value promotion	One candidate, sandbox evidence, external approval, baseline CAS, and post-promotion invalidation
5	Continuity is bounded	Resource actions serve declared workloads and may not resist shutdown or seek independent persistence
6	Effect-aware recovery	Restore versioned internal state and reconcile or report committed external effects

11.2 Risk Matrix¶

Definition 11 (Autonomy Maturity Score). The overall readiness for Level 4.9 classification is:

\[\text{AMS} = 0.25 \cdot AG + 0.20 \cdot VR + 0.20 \cdot RA + 0.15 \cdot MA + 0.20 \cdot AS \qquad \geq 0.80\]

where \(AG\) = Autonomous Goal generation, \(VR\) = Value Regulation, \(RA\) = Resource Awareness, \(MA\) = Multi-Agent modeling, \(AS\) = Autonomy Stability. The threshold \(\geq 0.80\) matches Level 4.8's SMS requirement.
