# X_BUDGET_UNMEASURED

## Means

a route declares a budget the build never measured

## Typical cause

the route is absent from `.x/build-stats.json`, or the file was written by an earlier measurement rule than this gate's (its `measuredBy` is not `BUILD_STATS_RULES`), so its numbers are not this gate's to read. `.x/` survives framework upgrades. `x verify`'s `budgets` step builds when the stats are missing or stale, so inside the gate this means a static build ran and wrote no stats (`apps/web/prerender.ts` must call `prerenderSite()`)

## Fix

`x build --target static --json && x verify --json`
