"""Shared records must announce themselves.

A record another user owns is that person's suggestion, not the operator's
settled practice — and the two are indistinguishable unless every surface that
hands one over says whose it is. These tests hold that line at the labelling
helpers and at the process→skill manifest, which is the most consequential
passive surface Grimoire has (each entry becomes an auto-surfacing skill file).
