D010 - Logging levels are defined once, in the shared conventions

Status: decided Date: 2026-08-29

What belongs at each level is defined in OOPS conventions §6, not in oops-log or any project.

Why: oops-log sets logging up; if each project defined levels, warn would mean different things in different tools.

Rejected:

• Level guidance in this crate's docs: consumers read the conventions, not this crate.
