Category-theoretic graph structures in Rust — strict Fong & Spivak hypergraph categories (cospans, props, Frobenius), with applied, magnitude, physics, and DL extensions, plus a term-language frontend (print/parse/eval/typed builder)

Framework-free Rust replication of arXiv 2510.26745v2: Node2Vec spectral dynamics, TinyNN geometry vs. memorization, and the initializer that decides between them - with measured findings

Durable, at-least-once agent messaging on SurrealDB: graph-edge messages with a two-tier bus — LIVE wake-up + CHANGEFEED catch-up over a persisted versionstamp cursor — surviving disconnects and restarts. Library-first Coalition<T> with CancellationToken/TaskTracker lifecycle.

SurrealDB persistence layer for catgraph structures (reboot on the SurrealDB Rust SDK 3.2.x)

Agentic coalitions in Rust — event-sourced temporal hypergraph topology with time-travel queries, coalition value/partition algorithms, and pluggable decision policies (Active Inference vs categorical magnitude, with a pre-registered A/B evidence trail) on a tokio runtime

Active-inference engine (Rust) + reproduction of Waade et al., Entropy 2025 — individual and emergent group-level generative models
