Observation

This page is generated from the code and must not be edited by hand.

Something read from storage. Immutable, and never revised.

An observation’s only claim is that a named observer, at a named version, read this from this location at this time. A later scan produces a *new* observation and both are kept, because the difference between two readings is itself evidence.

Carries extraction_tier, which measures distance from the bytes. It never carries an inference tier: an observation is not a conclusion, and the two axes are kept apart by keeping the models apart.
