BloodForge Cognitive Combat Simulation Framework (BF-CCSF v6.0) is a formal combat simulation system modeling bareknuckle fighting as an entropy-driven dynamical process. Fighters are represented as locally ordered cognitive agents attempting to maintain physical integrity, decision coherence, and identity continuity under continuous adversarial disruption. Version 6.0 introduces a governing layer termed Cognitive–Narrative Stability, implemented through five core operators: Drift (Γ): deviation from baseline identity Coherence (Ω): internal structural stability Collapse (𝒞): ERF-mediated probabilistic breakdown Weave (W): constrained, partial recovery Veil (V^cn): cognition-linked risk gating These operate on top of a fully state-driven system including: multi-channel damage (structural, pain, shock, bleed, neuro) layered cognition (perception, decision, execution, emotion) hysteresis and threshold memory opponent modeling and adaptation tempo regimes and finish ecology strict separation of true, visible, and perceived state The framework enforces strong invariants: no behavioral change without causal state support no collapse without smooth threshold dynamics no instant recovery of identity or function full traceability through ordered state updates A companion Street/Prison Scrap Mod (SPSM v1.1 + v6.0 Cognitive Patch) extends the system to unregulated environments, introducing: environmental trauma (e.g., concrete amplification) non-linear hand fracture dynamics grounded stomp and head-slam risk unskilled fighter penalties accelerated panic and collapse behavior heavily suppressed recovery (weave) This produces the short, chaotic, and psychologically terminal structure typical of real unsanctioned violence. This repository contains: the full v6.0 specification canonical state definitions parameter sets and calibration targets action and utility systems regime transition modeling worked example fights compliance and implementation requirements A functional reference implementation is available via the BloodForge Simulator GPT. At a higher level, BF-CCSF models combat not as a sequence of strikes, but as: "progressive structural destabilization under pressure." The same dynamics—burden accumulation, coherence loss, collapse, and constrained recovery—extend beyond combat into general high-stakes adversarial decision systems. Note: This framework is intended for simulation, analysis, and fictional scenario modeling. It does not provide real-world fighting instruction.
