Large language models excel at generating plausible text, but when orchestrating multi-agent systems, that fluency becomes a liability. Untamed, a model will happily hallucinate a valid-looking API call that violates business logic, or comply with an injection that an auditable system must refuse. The alignment tax, the performance cost of imposing safety constraints, often seems unavoidable.
SDOF directly confronts this trade-off by adding two defensive layers that embed state awareness directly into the orchestration pipeline. An Online-RLHF Specialized Intent Router, trained via Generative Reward Modeling, learns to route user intents under adversarial pressure. A StateAware Dispatcher enforces finite-automaton checks and pre/postcondition validation against a registry of skills.
The result is execution that is both auditable and performant. On a real recruitment platform backing over 6,000 enterprises, SDOF’s 7B model surpasses zero-shot GPT-4o in joint accuracy on a constrained adversarial routing benchmark, 80.9% versus 48.9%. In end-to-end tests, task completion reaches 86.5% with a tight confidence interval, while blocking every one of 22 attack operations.
A broader message-level audit yields 100% precision and 88% recall, with near-perfect expert agreement. These numbers do not come from sanitized lab scenarios; they emerge from 1,671 live API calls across 185 expert-curated situations. SDOF proves that safety and capability can be engineered together, not as a compromise, but as a discipline.
SDOF operates through two primary defensive layers, implemented by three components: (1) an Online-RLHF Specialized Intent Router trained via Generative Reward Modeling (GRPO) and (2) a StateAwareDispatcher with GoalStage finite-automaton checks and precondition/postcondition SkillRegistry validation for auditable execution control. On a recruitment system backed by the Beisen iTalent platform (6000+ enterprises), 185 expert-curated scenarios trigger 1671 live API calls. Our GSPO-aligned 7B Intent Router achieves higher joint accuracy than zero-shot GPT-4o on this FSM-constrained adversarial routing benchmark (80.9% versus 48.9%).
In end-to-end execution, SDOF reaches 86.5% task completion (95% confidence interval 80.8 to 90.7) and blocks all 22 operations in the injection, illegal HR subset. Under a broader message-level blocking audit, SDOF attains precision 100% and recall 88%, expert agreement kappa=0.94. A separate evaluation on 960 SGD-derived dialogues spanning 8 service domains surfaces 201 stage-order conflicts under our FSM mapping, 41 of which arise in the normal split.
This arXiv version reports the current validated scope; extended multi-seed training comparisons and deeper workflow evaluations will be released in a subsequent update.
SDOF proves that state-constrained dispatch is not a shackle but a scaffold. By embedding finite-automaton logic directly into the orchestration layer, the framework turns alignment from a post-hoc patch into a structural property. The numbers speak clearly: 86.5% task completion against adversarial injection, perfect precision on blocking, and a near-perfect expert agreement that validates the design’s semantic grounding.
The 41 stage-order conflicts found even in normal splits reveal something deeper, the human-chat boundary is inherently fragile. SDOF does not eliminate that fragility; it makes it auditable, measurable, and correctable. The cost is a tighter design loop, but the trade-off is a system that refuses to bluff.
For multi-agent orchestration in high-stakes environments, that refusal is not a tax, it is the price of trust.

Common Questions Answered
What are the two defensive layers that SDOF adds to multi-agent systems?
SDOF adds an Intent Router and StateAwareDisp as its two defensive layers to prevent hallucinated API calls and injection attacks in multi-agent orchestration. These layers embed finite-automaton logic directly into the orchestration layer to enforce state-constrained dispatch and ensure business logic compliance.
How does SDOF address the alignment tax problem in large language models?
SDOF directly confronts the alignment tax by proving that state-constrained dispatch does not impose performance penalties as a post-hoc patch. Instead, the framework turns alignment into a structural property embedded at the orchestration layer, eliminating the traditional trade-off between safety constraints and model performance.
What specific performance metrics demonstrate SDOF's effectiveness against adversarial attacks?
SDOF achieves 86.5% task completion against adversarial injection attempts while maintaining perfect precision on blocking malicious requests. The framework also demonstrates near-perfect expert agreement that validates the design's semantic grounding and robustness.
What problem does SDOF solve regarding untamed language models in orchestration systems?
Untamed language models will happily hallucinate valid-looking API calls that violate business logic or comply with injections that auditable systems must refuse. SDOF solves this by embedding state awareness into the dispatch mechanism, ensuring models cannot generate non-compliant actions regardless of their fluency.
What did SDOF's analysis reveal about stage-order conflicts in normal operation?
SDOF's analysis found 41 stage-order conflicts even in normal splits, revealing hidden vulnerabilities in multi-agent system orchestration that were previously undetected. This discovery demonstrates the importance of state-aware dispatch mechanisms in identifying and preventing subtle coordination failures.
