Unmanned aerial vehicle (UAV) command-and-control (C2) over MAVLink is safety-critical because protocol-valid attacks can disrupt vehicle movement, mission execution, and operator control even when the link remains operational. Existing UAV defenses often treat detection, blocking, and deception separately, leaving no integrated way to contain an untrusted MAVLink source while preserving trusted-operator control.
This paper presents CACD, a hybrid detection and enforcement architecture implemented as an in-path MAVLink/PX4 proxy for PX4 SIH/SITL simulation. CACD aggregates flow-scoped traffic into one-second windows for a Random Forest (RF) traffic-window classifier, complements RF inference with protocol-aware rate guards on untrusted HEARTBEAT, PING, and PARAM_REQUEST_LIST traffic, blocks unsafe or untrusted commands through runtime safety rules, and applies policy-driven session escalation and quarantine through a shared session-state manager. When deception is enabled, quarantined attacker flows receive bounded bursts of MAVLink-valid synthetic telemetry rather than a continuous fake stream; the trusted operator continues to receive real PX4 telemetry.
We evaluate CACD on a self-collected supervised MAVLink dataset of 9,645 one-second traffic windows across five attack scenarios and on live SIH/SITL tests covering the same categories. Offline group/log-split RF evaluation yields 99.38

AIEngOrchestrator-HITL: Human-in-the-Loop Process Intelligence for Resilient AI Systems
Razan Abualsaud
(Independent, Saudi Arabia)
Artificial Intelligence (AI) development processes remain limited in supporting lifecycle resilience under dynamic and context-dependent conditions. The separation of Machine Learning (ML) and non-ML processes weakens co-development and traceability, limiting sys- tematic reasoning about change across heterogeneous artifacts. Consequently, adaptation remains largely tool-driven rather than process-driven. We address this gap by introducing Human-in-the- Loop (HITL) process intelligence through AIEngOrchestrator-HITL, a conceptual extension of AIEngOrchestrator. While the baseline framework provides coordinated, executable AI development pro- cesses, its change reasoning remains primarily reactive and bounded by explicitly modeled dependencies. AIEngOrchestrator-HITL aug- ments this foundation with AI-assisted and human-guided reason- ing to infer missing dependencies, anticipate change impacts, and support proactive, context-aware process adaptation. We present the conceptual design and an evaluation plan for assessing its con- tribution toward process-level resilience under uncertainty.

A Resilience-Oriented Orchestration Framework for Mission Continuity in Multi-agent Autonomous Systems

Autonomous Multi-Agent Systems (MAS) operating in dynamic environments require resilient coordination mechanisms to maintain mission continuity despite operational disruptions. This paper presents a resilient orchestration framework that integrates runtime monitoring, interruption detection, recovery re-assessment, and re-orchestration within a unified lifecycle coordinated by a stateless Asynchronous Event Bus (AEB). By treating resilience as an intrinsic orchestration process, the framework enables recovery decision re-assessment and autonomous standby promotion without centralized replanning activities. Experimental evaluation in heterogeneous Search And Rescue (SAR) simulations demonstrates preservation of effective mission continuity and resilient recovery under varying failure conditions.

R²: Repairability-Preserving Recursive Repair for Multimodal Agentic Systems
Dominic Dabish
(San Diego State University, USA)
Current-incident success does not show whether a persistent repair preserves the evidence and rollback paths needed for the next failure. R² audits whether the repaired system can detect, localize, repair, and verify a different unseen fault within budget. It separates pre-authorization probes from sealed faults, confines proposals to registered actions, and assigns execution to deterministic code. In an authored study of four incident families, five policies, and 50 seeds (1,000 episodes), every policy fixed the visible incident. Across 400 sealed trials per policy, future-repair success was 4.0% for performance-only and regression-gated selection, 14.8% for static-quality and council selection, and 50.3% for R². False recovery was 33.8%, 18.5%, and 0%, respectively. The experiment replays four GPT-5.6 Thinking council records as fixed inputs and makes no live model calls. It validates the construct in a controlled simulator, not production prevalence or an agent-count effect.
