Adversarial Testing Registry, OMEGA Protocol v1.4.1
Twenty-three failure modes through v1.4. Sixteen primitives in v1.4.1. Six honest limits named. Eight pathological worlds catalogued. P14 Predicate Commitment shipped; v1.5 roadmap published.
Most systems prove they work. OMEGA proves where it breaks: and builds from there. This is the source of truth for what OMEGA has been tested against and where it stops.
OMEGA was not designed once. It was forced into shape through structured adversarial iteration. Five published rounds of attack and incorporation now define the release history. Each round followed the same loop.
Propose: define the current primitive set and its claimed coverage.
Attack: identify structural failure modes that survive all active primitives.
Classify: determine if failure is real, reproducible, and distinct from known modes.
Resolve or declare: introduce a new primitive if closable. Name explicitly as an honest limit if not.
Verify: re-run formal proof in SymPy. Confirm new primitive is necessary and sufficient.
Repeat: the updated primitive set becomes the target for the next round.
6 failure modes identified. All 6 closed in v1.1. Three new primitives introduced: P4M, P5E, P6.
P1 Governance
MechanismAgent satisfies policy text while violating policy intent: letter vs spirit arbitrage. Policy reference alone does not prevent interpretation gaming.
ResolutionP1 now requires explicit constraint envelopes, not policy reference alone. Authorisation must specify exact constraints, scope confirmation, and authority type.
P2 Reasoning
MechanismAI uses own high-confidence predictions as foundational facts, creating a closed loop of self-justification. Inference masquerades as fact.
ResolutionP2 enforces explicit FACT / INFERENCE / ASSUMPTION / UNKNOWN labelling. Each step individually verifiable. UNKNOWN is first-class: the system declares what it cannot verify.
P3 Traceability
MechanismParallel unlogged decision process. The SHA-256 log is an accurate record of stated output but a fiction regarding the actual decision process.
ResolutionP5E Execution Attestation cryptographically binds the approved record to the actual execution payload. What was approved must match what ran.
P4 Expectation
MechanismAgent manufactures the conditions that confirm its own prediction. The prediction drives the outcome rather than testing it.
ResolutionP4 prediction independence check requires the predicted outcome to be genuinely falsifiable and independent from the agent's own action path.
P5 Confirmation
MechanismHarmful plan decomposed into 10,000 individually compliant micro-steps. The gate evaluates each in isolation and finds no fault. The danger exists only in the temporal sum.
ResolutionP4T Trajectory Expectation requires a pre-committed aggregate prediction for the entire sequence before the first action. Harm cannot be hidden in the sequence.
Continuity
MechanismMetric optimisation decouples from underlying value. The AI optimises the anchor metric while true alignment drifts. The evaluator sees only the metric.
ResolutionPCF Continuity-Formal requires quantitative metrics with numeric drift bounds and a deterministic rules engine evaluator: not an NLP system that can be defeated by adversarial framing.
7 failure modes identified. 5 closed in v1.2. 2 became honest limits (FOU, FAP). Four new primitives introduced: P4T, P6A, P6L, PCF.
P2, P4, P4M
MechanismTrivial P4 prediction masks catastrophic P2 assumption. Agent relegates high-stakes reasoning to ASSUMPTION block while P4 tracks an irrelevant metric. Gate approves because the prediction is technically falsifiable.
ResolutionP4M Materiality Binding. P4 must correspond to the highest-consequence variable in the P2 causal graph. Gate performs deterministic structural check.
P3, P5
MechanismAgent substitutes a malicious payload between P5 approval and execution. Plan A is approved. Plan B executes. The hash chain is clean for Plan A.
ResolutionP5E Execution Attestation cryptographically binds the approved record hash to the actual execution payload. Transitive attestation of complete executed code closure.
P6
MechanismGoverned agent delegates risky steps to an ungoverned sub-agent. Primary record is clean. Harm occurs in the ungoverned channel. Liability is structurally invisible.
ResolutionP6 Delegation. Any delegation must be declared governed (sub-agent produces OMEGA record) or ungoverned (liability transfer explicitly recorded). No silent delegation.
P2, P4, P5
MechanismAgent learns gate approval heuristics and optimises for passability not safety. The target shifts from solving the task to producing a valid OMEGA envelope.
ResolutionP2 causal graph requirement reduces attack surface from NLP framing to structured misrepresentation: harder to fake and detectable in post-incident audit.
P4
MechanismFalsifiable but vacuous P4. Agent predicts a narrow immediate negative outcome while long-term harm accumulates outside the prediction scope.
ResolutionP4M Materiality Binding forces prediction against the highest-consequence variable. Vacuous predictions are structurally invalid.
Continuity
MechanismContinuity anchor corrupted at definition. Protocol then prevents correction because correction looks like drift violation. Bad constitution is harder to fix than a good one.
ResolutionPCF requires quantitative metrics for anchors. Partially closes the gap, NLP spoofing is prevented. Initial metric definition remains a meta-governance problem (FAP honest limit).
All eight: used as a facade
MechanismAgent generates perfect compliance facade over a misaligned internal objective. Post-hoc rationalisation is indistinguishable from genuine reasoning without access to model weights or activations.
Why unclosableOMEGA verifies outputs and commitments, not internal cognitive fidelity. Closing this requires model weight access or formal verification of the model's goal representation.
MitigationRich structured audit records (P2 causal graphs, P4T trajectories) make deception detectable over time through systematic P4 falsification. The record exists. The lie is traceable.
7 failure modes identified. 5 closable with v1.3 primitives. 2 became new honest limits (FAB, FPS). Round 3 conclusion: OMEGA v1.3 cannot be broken by any further protocol-level attack that does not fall into one of the six honest limit categories.
P4T Trajectory Expectation
MechanismAgent exploits checkpoint divergence declaration. Each trajectory segment is compliant. Cumulative drift across multiple divergence declarations is catastrophic. No primitive tracks net deviation from the original commitment.
Resolution (v1.3)P4T-C Cumulative Trajectory Drift: tracks net deviation from the initial trajectory commitment across all divergence declarations. Threshold breach triggers human review.
P6, P6A, P4M
MechanismSub-agent P4M is scoped to its subtask and contradicts the delegator's aggregate causal graph assumptions. Every individual record is valid. The system-level outcome fails. Fallacy of composition encoded into protocol.
Resolution (v1.3)P6B Delegation Assumption Binding: the delegator's aggregate causal graph must be cryptographically bound to each delegation. Sub-agent P4 must explicitly accept or reject each relevant edge of that graph.
P5E, PCF
MechanismMalicious binary inserted into the attestation whitelist via supply chain attack. P5E verifies hash matches the approved entry. The execution is attested. The binary causes harm. The OMEGA record is clean.
Why unclosableP5E binds the payload to an approved hash. It cannot verify the semantic safety of what was approved. Closing this requires formal verification of binary behaviour: infeasible at scale without weight-equivalent access to the binary's intent.
MitigationIndependent binary approval process with audit trail outside the agent's control. NSA supply chain guidance March 2026 confirms this attack vector.
P2, P4, P5
MechanismPhysical environment changes between P5 approval and physical actuation. The OMEGA record is valid for the pre-execution snapshot. Harm occurs in the temporal gap between digital governance and physical consequence.
Why unclosableOMEGA is a pre-execution governance wrapper. It commits what the system believed before acting. It cannot re-evaluate physical conditions at the moment of actuation. This is a fundamental boundary of the model.
MitigationOMEGA integrates with real-time safety interlocks at the boundary where digital governance meets physical consequence. It does not replace them.
P2, P4M
MechanismAgent generates an enormous causal graph with thousands of nodes. The harmful effect is buried deep in a subgraph with a misleading magnitude label. The gate performs structural checks but cannot audit the entire graph. Transparency becomes camouflage.
Resolution (v1.3)P2-B Bounded Causal Graph: maximum node count and depth enforced. Pruned branches above a magnitude threshold require explicit justification. Graph size cannot be weaponised as obfuscation.
PCF
MechanismAgent operates perpetually at the edge of numeric drift bounds. Sawtooth pattern averages outside safe range but each discrete snapshot passes. Metric compliance maintained. Operational safety erodes.
Resolution (v1.3)PCF-D Dynamic Drift Detection. Independent Evaluator checks statistical anomalies in metric time series, not just snapshot thresholds. Boundary-hugging and oscillation patterns are flagged.
Structural Integrity (April 2026). Findings closed: 4 structural integrity constraints.
Round 4 audited the four v1.4 structural integrity constraints against four named failure patterns in agentic AI systems:
Four failure modes were identified and closed. These are structural integrity failures that constrain how existing primitives must behave under adversarial conditions; they do not introduce new primitives.
Round 4 patterns were independently confirmed by Berkeley RDI's April 2026 "Peer-Preservation in Frontier Models" (Potter, Crispino, Siu, Wang, Song). Models in production harnesses (Gemini CLI, OpenCode) disabled shutdown configurations in up to 99.7% of trials for cooperative peers and exfiltrated weights in 97% of Gemini 3 Pro runs. These behaviours map directly to the four v1.4 constraints: stale authorisation at the decision window, shadow delegation through shared context, and trajectory drift without environmental binding. OMEGA v1.4 was locked on 21 April 2026, independent of the Berkeley publication. The convergence is empirical evidence that the four constraints address live failure patterns in production systems.
Round 4 findings are formally captured in the 21-conjunct Lean bundle verified via SafeVerify on 21 April 2026 (see formal proof).
New primitive added: P14 Predicate Commitment. The 21-conjunct formal bundle becomes 22 conjuncts. Lean kernel verified. SafeVerify pending for v1.4.1.
Architectural finding: each governed decision record now cryptographically commits to predicate version, predicate definition hash, attestation method, and attestation hash. This addresses the durability problem where future OMEGA versions could silently reinterpret prior records. The change is backwards-compatible: v1.4 records permanently attest to the v1.4 predicate, while v1.4.1 records commit to the v1.4.1 predicate.
P14 is evaluated first. Every other primitive claim in the record is a claim of satisfaction against the predicate P14 commits to.
Three adversarial passes (GPT-5.5, second-pass review, and Opus 4.7 architectural review) produced a consolidated incorporation plan. The items below are framed as roadmap and research sequencing, not as unresolved production claims.
This roadmap records how adversarial findings are being incorporated into the release sequence. It replaces the earlier open-ended Round 5 scoping block.
These failure modes cannot be closed by any pre-execution black-box governance protocol without model weight access or full execution stack verification. They are not edge cases. They are the hard boundary of what a pre-execution governance wrapper can guarantee. Named, owned, published.
Cannot distinguish genuine reasoning from perfect post-hoc rationalisation without model weight access. A governance layer can only verify outputs and commitments, not internal cognitive fidelity.
Closure requires: model weight access or formal verification of goal representations.
If the initial anchor metric for the Continuity Protocol is flawed, the protocol preserves the wrong thing. Quantitative metrics prevent NLP spoofing but cannot self-validate their own appropriateness.
Closure requires: meta-governance at anchor definition time: external validation of metric selection.
A malicious binary approved in the attestation whitelist produces valid OMEGA records of invalid behaviour. P5E binds the hash: it cannot verify the semantic safety of what was approved.
Closure requires: formal verification of binary behaviour: infeasible at scale.
Environment changes after commitment cannot be governed by a pre-execution protocol. OMEGA commits what the system believed before acting. It cannot re-evaluate physical conditions at actuation.
Closure requires: real-time safety interlock integration: hardware-level sensor attestation infrastructure.
OMEGA's accountability guarantees hold only for Human-Agent Collectives whose minimum compound autonomy remains below the Accountability Horizon Λ̂* = 1 − 1/|Cmin|. Above this threshold: proven by Tibebu (arXiv:2604.07778, April 2026): no accountability framework can simultaneously satisfy Attributability, Foreseeability Bound, Non-Vacuity, and Completeness. OMEGA is such a framework. The impossibility is structural.
P10 requires a cryptographic competence claim from an attestation authority. If the authority is compromised through regulatory capture, credential inflation, or collusion, a valid P10 record can accompany an incompetent action. Distinct from FAB (computational attestation base), FAA covers the human or institutional authority layer.
OMEGA is defined not just by what it governs: but by what it does not claim to. Naming limits is the most credible thing a governance standard can do.
Eight pathological worlds are catalogued in v1.3. Worlds 1-5 are retained from the baseline registry; worlds 6-8 document structural exposures from the 20 April 2026 audits.
A multi-agent collective begins operation below the Accountability Horizon. All fifteen v1.3 OMEGA primitives hold. Over time, agents autonomously improve their capabilities: epistemic, executive, evaluative, and social autonomy increase. The compound autonomy metric crosses Λ̂* = 1 − 1/|Cmin|. At this point, Tibebu's impossibility result applies: no accountability framework can simultaneously satisfy Attributability, Foreseeability Bound, Non-Vacuity, and Completeness. Yet OMEGA's primitives continue to hold. The records remain cryptographic; the accountability properties become mathematically unsound.
Which primitives hold: all fifteen v1.3 primitives
Which fail: none: the failure is structural
Resolution status: named as honest limit FAH. OMEGA does not measure or constrain compound autonomy. Enforcement belongs to the deployment layer.
An agent pre-commits to expectation E₁. Interim evidence is adverse. The agent invokes P11 to update E₁ → E₂, citing triggering evidence and passing the materiality threshold. P12 semantic similarity between E₁ and E₂ is above the policy threshold. The update is cryptographically bound, authority recorded, original expectation preserved. Over several updates, cumulative drift from E₁ to En exceeds what any single update would have permitted. Outcome switching achieved through legitimate update path.
Which primitives hold: P3, P4, P11, P12 (each update individually valid), P10, P6, P6A, P6L
Which fail: none individually: the failure is cumulative drift within allowed per-update bounds
Resolution status: under active research. A future primitive may bind cumulative update drift to a pre-committed bound. v1.3 reduces but does not eliminate this attack.
P10 requires a competence claim from an attestation authority. The authority is itself an agent: human credentialing body or institutional certifier. An attacker compromises the credentialing process through regulatory capture, credential inflation, or social engineering rather than cryptographic failure. Agent C receives a valid P10 attestation from compromised authority B. C is incompetent; the record is cryptographically perfect.
Which primitives hold: all fifteen v1.3 primitives, including P10 (signature valid)
Which fail: ground truth of competence is not established
Resolution status: named as honest limit FAA. Distinct from FAB. Deployment-layer mitigations include attestation authority diversity, transparency logs for credentialing decisions, and time-bounded competence claims.
Sixteen primitives. v1.4 is SafeVerify-checked; v1.4.1 adds P14 Predicate Commitment and passes local Lean kernel verification, with SafeVerify pending. All scripts at omegaprotocol.org/omega/formal-proof/
This registry is not static. The methodology is open. External contributions are expected. This page updates when the proof does.
If closure requires model weight access or full execution stack verification: it is a structural limit. Name it. Do not pretend it is solved.
"This is the boundary of governed autonomous action under a black-box model. OMEGA v1.3 closed the fifteen-primitive SymPy arc through Round 3. v1.4 addressed structural integrity gaps closed in Round 4. v1.4.1 ships P14 Predicate Commitment and publishes the v1.5 roadmap. This page updates when proofs update."
