Core fixtures for the v0.9 graph model release in January 2026 are nearly finished. I’d hoped to wrap this up before the holidays, but I’m stopping at the 90% mark. I’d rather re-evaluate with fresh eyes in January than rush the final validation now.

Done for the year.

RDF reification for complex image semantics often leads to structural bloat.

We use the Property Graph to keep Modifiers and Events as first-class citizens. No "triple-spaghetti," just maintainable logic and performance.

Logic first, serialization second.

Wrestling with mapping free-text coin descriptions to our graph. The NLP/RE pipeline is almost ready, but semantic ambiguity is a beast. Human language nuances strike back every time.

Definitely not a bash script job for the lunch break.
