Concepts

Omena is not a collection of independent regex checks. It keeps syntax, identity, cross-file facts, query results, and product rendering in separate layers so uncertainty can remain visible.

• Semantic analysis follows facts from source text to editor and CLI results.
• Evidence and transform safety explains why transforms can apply, preserve, or reject without inventing certainty.
• Positioning compares the product boundary with adjacent CSS tools.
• Performance evidence explains how latency claims are measured.
