Module property_names 

Property-key constants shared by producers and the ingestion stack.

Kept apart from the property module, which is gated behind the server feature because its Property type carries sqlx impls: client crates need these names to honor the reserved namespace before they send anything, and must not pull a database driver in to do it.

Constants

RESERVED_PROPERTY_PREFIX

Reserved, server-written property namespace. A client-supplied property whose key starts with this prefix is dropped at ingestion.
