X_SCAFFOLD_OVERRIDES_EMPTY
Means
no @ultimat3/* workspace manifests were found, so the smoke app would install from the npm registry
Typical cause
scripts/scaffold-smoke-overrides.ts run outside the repo root, or against a tree with no packages/ — writing {} would silently test the published packages instead of the working tree, which is the one thing the scaffold smoke job exists to avoid
Fix
bun run scripts/scaffold-smoke-overrides.ts ./smoke-app --json from the repo root
