Boundary-Triggered Halt Control Systems:

This document is structurally aligned with and superseded in canonical form by: https://doi.org/10.6084/m9.figshare.31937418⁠�Navigation and document structure are defined in the Master Index: https://doi.org/10.6084/m9.figshare.31919058⁠�This document defines control systems that enforce halt when boundary conditions are reached.This document discloses boundary-triggered halt architectures for computational and cyber-physical systems operating under recoverability constraints.The system model assumes execution continues only while at least one recoverability-preserving action exists. When all admissible actions reduce recoverability, the system transitions to a halt state and produces a null output.This publication describes control architectures that implement boundary-triggered halt behavior, including state-space interpretation, detection-to-actuation pathways, and enforcement mechanisms across computational and physical systems.Representative architectures include:computational boundary detection systemsrecoverability-gated actuation interlockspre-irreversible commitment boundary controllersThe purpose of this publication is to place boundary-triggered halt control architectures into the public technical domain and establish prior art for recoverability-constrained control systems.Open use declarationThis work is made publicly available for use, implementation, and modification without restriction. No royalties or permission are required. No endorsement is implied.Condition of use:The system must not be used to:make decisions on behalf of humansprovide recommendations or advisory outputsact as a governance or authority mechanismThe system is limited to detection of boundary conditions and enforcement of non-execution. All responsibility remains with human operators.This work operates within a recoverability-constrained system framework and does not modify the admissibility conditions defined in the core.Core reference: https://doi.org/10.6084/m9.figshare.31937418⁠Framework index: https://doi.org/10.6084/m9.figshare.31919058⁠
