Abstract:	This paper presents a socio-technical redesign of TAFNAVEGA to support its operation in thesis and dissertation repositories, guided by two principles: explainable information retrieval and lightweight vocabulary governance. The study adopts a qualitative, design-oriented approach structured in five phases: discovery and planning; terminological curation and modeling; operation of a lightweight Business Process Management approach (BPM-lite) workflow for indexing and controlled term inclusion; linking question to be answered (QR) to faceted combinations with core facet categories (CAFTE) to test explainability; and synthesis of the resulting artifacts. The results indicate reduced terminological ambiguity, improved retrieval explainability (i.e., "why an item was retrieved"), and the generation of minimal decision traces sufficient to support institutional curation without increasing bureaucratic overhead. The study demonstrates that repositories can function as knowledge organization ecosystems when they combine an operational faceted vocabulary, minimal curatorial roles, and a modular infrastructure.
