# BRAND_CONSTRAINT_WARNING

> BRAND_CONSTRAINT_WARNING is a lint warning: an explicitly requested inspect-only Brand constraint failed or could not be measured.

- **Tier:** lint
- **Severity:** warning

## What triggers it

A StyleSpec `contrast`, `accent-area`, or `mono-role` constraint with `action: "warn"` inspects final Scene paint. Transparent or unresolved compositing contexts report unmeasurable evidence without inventing a ratio.

## How to fix it

Inspect the structured measurement payload and adjust the role/slot paint or the constraint threshold. The renderer deliberately preserves the authored artifact and never repaints or relayouts it.

Run `am verify diagram.mmd --json`, inspect this code, and apply the smallest source or typed mutation that clears it. If it persists after two mechanical attempts, return the warning and ask for human review.
