We published a four-level data classification scheme on the wiki. Why does nobody apply it, and what would fix that?

Labels without consequences die quietly. Attach classification to enforced defaults in Terraform modules, propagate tags to every copy of the data, and give engineers twenty worked examples instead of a taxonomy lecture.

Grounded in researched DevOps, SRE and platform engineering interview loops, written to a senior-engineer editorial bar, and never padded to hit a word count.
