01 / Development sequence
Six deterministic fixture selections prove the mechanism without pretending they are public content.

02 / Rules
Randomness is constrained by eligibility before selection.
Filter first
Kind, lifecycle, spatial class, Atlas availability, dossier availability, relationship category, explicit time-event type, and date precision can constrain candidates.
Publishability first
Public mode removes unpublished, private, and development fixtures before hashing the seed.
No coordinate payload
The discovery document and Surprise payload intentionally omit latitude and longitude entirely.
