Activation geometry / training governance / alignment evaluation
Arca Futura develops systems for reading, evaluating, and governing model behavior at the structural level - from depthwise activation geometry to diagnostic alignment suites.
Training-governance research built on activation geometry and real-time instability signals.
A 77-model preprint study of recurring depthwise activation structure in decoder-only LLMs.
A diagnostic suite for strategic misalignment and instrumental convergence under pressure.

Earlier projects explored memory, tutoring, and adversarial evaluation. The current work is narrower and stronger: measuring the internal geometry of model training, turning those signals into governance tools, and publishing diagnostic benchmarks with careful evidence labels.
Current focus
AEGIS is a training-governance system that monitors internal activation geometry during model training. Instead of waiting for loss curves to expose failure, it tracks structural signals such as PCA movement, tension acceleration, and layer-ratio volatility.
The public claim is deliberately modest: AEGIS is an active research and infrastructure effort, grounded in the Hau Curve preprint and supported by controlled pilot runs. Production-scale validation remains the next frontier.
Depthwise activation structure documented across a 77-model cohort.
Controlled runs indicate internal geometry can move before obvious external failure.
Evidence is infrastructure-oriented and diagnostic, not a blanket claim about deployment safety.
Public research
The Hau Curve paper identifies a recurring tri-phasic activation geometry across decoder-only transformer models, with early-training convergence and stable depthwise landmarks. This work became the foundation for AEGIS.
StratEval is a diagnostic evaluation suite for instrumental convergence and strategic misalignment under structured pressure. It is meant to characterize elicited behavior under authored scenario frames, not rank models for deployment.
