Auto-graded broader coverage — sourced by an automated screen and graded on default bands, not the sector-calibrated bands the curated screener uses. A "Mixed (early)" here is NOT the same bar as a curated grade; these are auto-screened candidates for your own research, shown as of their surface date (2026-07-25), not the curated Frontier signal.
