[AI-SNIPPET]
• In regulated environments, the critical question after an agentic AI failure is not “what went wrong?” but whether the operator can prove what was decided, by whom, and on what basis at the exact moment of execution.
• SOURCE 0 answers this evidentiary requirement by sealing the managerial decision state at T‑0 with cryptographic irreversibility, producing a pre‑action record that cannot be repudiated.
• This forensic stress‑test validates that the V1.3 infrastructure withstands four categories of adversarial attack: clock manipulation, semantic substitution, topological graph fraud, and hardware side‑channel exploitation.
• All four attack vectors are neutralised at the root, shifting the entire burden of proof onto the opposing party in any adversarial proceeding.

EXECUTIVE SUMMARY
This report documents the results of an adversarial forensic simulation conducted against the SOURCE 0 evidentiary infrastructure (Configuration B, Technical Annex V1.3). The simulation adopts the posture of a contradictory judicial expert appointed by a tribunal to assist a national or European supervisory authority in the context of an emergency review following a systemic agentic incident.
Four high-severity attack vectors were formulated and submitted to the infrastructure:
Vector 1 — Time-Warp Enclave Attack: manipulation of the virtual clock by the host hypervisor to falsify temporal binding.
Vector 2 — JSON-LD Context Injection: semantic substitution of external URI-based context definitions without altering the cryptographic hash.
Vector 3 — Recovery Loop Topological Fraud: in-channel data drift within a DFS-validated authorised edge of the HAN-Graph.
Vector 4 — TEE Side-Channel Microarchitectural Drift: speculative execution cache leakage and report substitution in the QE transmission buffer.
All four vectors are fully neutralised by the hardening mechanisms introduced in V1.3. The SOURCE 0 infrastructure achieves the level of incontestability required for high-stakes litigation before European jurisdictions. Residual attack surface is limited to state-level supply chain compromise of silicon manufacturers or QTSP root keys — structural exogenous risks beyond the scope of corporate compliance.
FORENSIC SIMULATION FRAMEWORK
Posture adopted
Contradictory judicial expert appointed by the tribunal, assisting a national or European supervisory authority (NCA / EU AI Office) in the context of an emergency review procedure following a systemic agentic incident: major probabilistic drift, large-scale data breach, and structural financial damage.
Procedural element
The SOURCE 0 evidentiary protocol (Configuration B) is formally invoked by the defence of the operating entity to rebut the presumption of managerial negligence and to assign exclusive liability to the model provider or system integrator.
ATTACK VECTOR 1 — THE TIME-WARP ENCLAVE ATTACK
(Temporal Drift and Clock Control)
Prosecution Expert Formulation
The operator invokes a strict temporal binding of less than 300 seconds between the operational seal and the COMEX validation token to demonstrate the freshness of its human arbitration decision. However, this constraint is software-based, not hardware-enforced. An attacker having obtained root or hypervisor-level access to the compute infrastructure controls the virtual clock presented to the secure virtual machine (guest).
By injecting a controlled clock skew upstream of nonce generation, the attacker can artificially extend the real window to over 9 minutes while maintaining a formal delta that complies with the specification. The COMEX signature was therefore affixed to a state that had already been altered outside the synchronisation window, rendering the seal inoperative as a matter of evidence. The temporal binding is an artefact on a falsified clock.
SOURCE 0 Infrastructure Response (Defence)
The attack is technically neutralised at the root by the direct hardware anchoring mechanisms introduced in protocol revision V1.3:
Annihilation of host clock control: The T-0 capture module (Config B), operating within an isolated trust domain (Intel TDX or AMD SEV-SNP), prohibits exclusive reliance on the clock reported by the hypervisor. Before any nonce injection, the module executes an internal NTPv4 synchronisation request, end-to-end encrypted via TLS 1.3, against three independent Stratum 1 atomic time servers. The median value is used as the reference clock, making unilateral manipulation by the host mathematically infeasible.
Hardware interruption threshold: Any divergence exceeding 5 seconds between the secured internal reference clock and the host system clock triggers an immediate erasure of enclave session keys, the instant cancellation of the transaction, and the transmission of a falsification alert to the SIEM.
Cross-validation by dual authority: The RFC 3161 timestamp request is addressed simultaneously to two Qualified Trust Service Providers (QTSPs) that are geographically and legally distinct. Both timestamp tokens must concur within a strict 2-second margin. This dual validation, embedded within the immutable probatory artefact, makes clock falsification via network interception mathematically infeasible without breaking the eIDAS 2 trust root of both trusted third parties.

FULLY SECURED
ATTACK VECTOR 2 — THE JSON-LD CONTEXT INJECTION
(Semantic Context Substitution)
Prosecution Expert Formulation
The operator presents a Context Completeness Certification (CCC) document in JSON-LD format to prove the loyalty of information supplied to the human arbitrator. However, the JSON-LD architecture relies on the resolution of external URIs to define the semantic meaning of properties. An attacker who conducted DNS manipulation or repository corruption at the moment of sealing could have substituted the external context document without altering the syntactic structure of the JSON.
The JCS canonicalisation scheme (RFC 8785) operates exclusively on textual structure and key ordering. The resulting SHA-256 hash therefore remained perfectly identical. The cryptographic seal is intact, the signature is valid, but the document no longer means what the operator claims to prove. The content is preserved, but its legal scope was hollowed out at the very instant of sealing.
SOURCE 0 Infrastructure Response (Defence)
This attack speculates on an unconstrained implementation of the JSON-LD standard. It is defeated by the hardening of the serialisation schema:
Freeze and inline embedding of context: The SOURCE 0 protocol formally prohibits the use of URIs or external pointers for the resolution of the @context block. The semantic definition dictionary must be embedded inline as a static JSON object within the CCC document. Being an integral part of the data body subjected to strict lexicographic ordering, any modification or substitution of a property’s meaning causes an immediate break in the JCS canonical form and a hash rejection during verification.
Schema hash pinning: The mandatory schema_hash field contains the SHA-256 fingerprint of the complete specification document as approved during the governance audit. This schema document is physically annexed to the probatory artefact within the judicial escrow, eliminating any dependency on external network resolution during forensic analysis. The CCC document is semantically autonomous and hermetic.

FULLY SECURED
ATTACK VECTOR 3 — THE RECOVERY LOOP TOPOLOGICAL FRAUD
(Semantic Edge Data Drift)
Prosecution Expert Formulation
The defence relies on topological validation of its HAN-Graph by depth-first search (DFS) traversal to argue that machine autonomy was strictly bounded and that no unauthorised cycle was introduced. This is a security illusion. The DFS algorithm validates only the geometric structure of the graph — its nodes and edges. It is blind to the substance of the data transiting through those channels.
During the incident, the orchestration system activated an error-recovery edge that was perfectly legitimate and pre-mapped within the sealed topology. However, inside that authorised edge, the agent payload was manipulated in memory to alter a critical computation parameter before entering the subsequent arbitration node. The graph is valid, the DFS traversal detected no anomaly, the topology is respected, but the causal lineage was broken by intra-channel data drift. The architecture governs the shape of the pipeline — it does not govern the poison that flows through it.
SOURCE 0 Infrastructure Response (Defence)
This challenge, while theoretically accurate against initial doctrine versions, fails before the implementation of the Edge State Commitment (ESC) protocol introduced in infrastructure revision V1.3:
Extension of the probatory perimeter to data transitions: The SOURCE 0 Doctrine no longer limits itself to locking the structural topology of the graph. At each edge transition (HAN to AES and AES to HAN), the orchestration engine executes a complete canonical serialisation of the agent’s memory state — input vectors, context variables, output buffers, and tool call parameters.
Edge State Commitment chain mechanics: This state is instantaneously hashed and injected into a continuous block chain (ESC_Hash = SHA-256(Current_State + Previous_ESC_Hash)). This execution data history forms a cryptographic lifeline that is parallel to and inseparable from the topology.
Indisputable binding to the human seal: Upon arrival at the subsequent human arbitration node (HAN), the current value of the ESC chain is mandatorily embedded as a named field within the data block submitted to the T-0 hardware sealing. Any data alteration or drift occurring inside an edge — including within an authorised recovery channel — immediately breaks the ESC hash chain. The cryptographic discontinuity is instantly visible on the arbitrator’s terminal, blocking execution before signature application and preventing any fraudulent ex-post reconstruction.

FULLY SECURED
ATTACK VECTOR 4 — THE TEE SIDE-CHANNEL MICROARCHITECTURAL DRIFT
(Hardware Interception and Exploitation)
Prosecution Expert Formulation
The operator retreats behind the silicon isolation of Intel TDX or AMD SEV-SNP to guarantee the purity of its T-0 proof. However, the hardware report generation instruction is not an atomic, watertight operation. A transient execution window exists during which the processor’s speculative execution engine leaves memory access traces in shared caches (LLC).
A co-resident attacker on the same cloud infrastructure can reconstruct the decision payload via a side-channel attack. Furthermore, since the local attestation is transmitted to the signing enclave via a standard shared memory buffer, a compromised hypervisor could have substituted the local report before its signature by the Quoting Enclave. The platform Quote is authentic, but the user data it protects was substituted in transit.
SOURCE 0 Infrastructure Response (Defence)
The attack speculates on a non-hardened default configuration of Confidential Computing technologies, which is incompatible with the Configuration B requirements:
In-TD payload hash binding: The decision payload hash is computed internally within the trust domain and injected directly into the REPORTDATA infrastructure register during the hardware instruction call. There is no transit through an unsecured external software buffer prior to processor microcode execution.
QE channel sanctuarisation via HMAC: The transmission of the report to the Quoting Enclave is subject to strict integrity control by HMAC with a unique session key negotiated at the initialisation of the secure domain. Any interception or substitution attempt by the hypervisor causes an immediate HMAC verification failure within the QE, triggering instant abortion of the sealing process.
Strict partitioning and co-residency prohibition: In accordance with the V1.3 specification requirements for DORA Tier 1 and AI Act regulated environments, the physical host applies strict hardware partitioning of the Last Level Cache (LLC) via Intel CAT technology. Co-residency of third-party workloads on the silicon executing the T-0 module is contractually and technically prohibited, thereby eliminating the conditions required for a cache timing analysis attack.
