We present Hyalinos, a transparent type discovery framework for Pharo that combines HYPHE for multi-source type inference with Mycelium as an open type knowledge storage. HYPHE integrates several existing tools for type inference, type heuristics, results from offline test profiling, and then merges them using one of avail- able reconciliation strategies. Mycelium stores collected types in a GitHub repository, enabling community-wide type knowledge sharing and synchronises with a local type storage. The bundle integrates seamlessly into Pharo IDE, providing existing type infor- mation during coding and methods investigation. Hyalinos is an open-source tool available on https://github.com/hyalinos.
