The compat-range floor was computed by finding the latest LTSC strictly less than host.Build. That works for an exact LTSC host but breaks for any host past the latest LTSC: a WS2025-generation build like 26200 picks 26100 as the floor, excluding WS2022 (20348) containers even though the stable ABI policy permits them. Find the largest LTSC <= host.Build and step one entry back for the floor (or stay put if it is already the first entry). This keeps the floor at the previous LTSC across an entire host generation.
