Events
A log of everything that happened at a moment in time, from meals and trips to deploys and home alarms, fed by people, scripts and Home Assistant.
Where Knowledge holds what is true, Events holds what happened: a meal, a trip, a purchase, a deploy, the alarm going off. Events are append-mostly and kept forever.
Each event has a dotted kind (meal.eaten, travel.trip, dev.deploy), a time with a precision (exact, day, month or year), free-form data, and references to nodes in the vault. Spans like a trip can have children.
It's written to by me, by an assistant through MCP, by Home Assistant and by my deploy pipelines, and read back with "what did we do last July?"
