What should an event record remember?

A small schema experiment

Sample draft content. This illustrative note is not a production architecture or a published account of Peter’s implementation.

An extracted value is easier to evaluate when its source travels with it. A record might separate the event identity from observations about it.

type Observation = {
  sourceUrl: string;
  observedAt: string;
  field: string;
  value: string;
};

Questions left open

How should conflicting observations be represented? When does a newer observation supersede an older one? What evidence should a person see before deciding to trust the result?

These questions matter more than committing to the example shape above.
