One missing badge image broke typecheck. A story about type erasure, optional properties, and parametrized contract tests guarding per-locale JSON content.

My content security gate auto-rolled back the very article announcing it. False positive, cheap fix, and the best proof the fail-closed design works.

We deleted the daily 6+6 article cap and went event-driven: per-entry cursor, cycle budgets, and a local bge-m3 embedding dedup.
