What is published here: original architecture notes, reference models, and decision records drawn from real enterprise, cloud, and solution-architecture work — frameworks (TOGAF, ArchiMate), capability and integration modelling, and the reasoning behind specific design calls. What is not: client names, commercially sensitive specifics, or vendor-proprietary material; examples are generalized to the pattern, not the engagement.
