Tell me what you observe and when it began. If a decisive detail is missing, I will ask one short question.
Aquarium assessment · private by design
Your aquarium has a history.A useful decision begins by ordering what changed.
MACI Guardian Free separates facts, hypotheses and next steps with a deterministic rules engine. It is not a chatbot and does not send your question to any server.
Local public engine
A structured assessment that stays in your browser.
Describe the system and its evolution. The engine identifies known signals, limits immediate action, and clearly separates MACI principles from general technical knowledge.
