A 7-day minimum-release-age window blocks nearly every recent npm and PyPI smash-and-grab compromise

Problem

Most recent npm/PyPI compromises were detected and yanked within hours: debug+chalk (~2h live, 2025-09), litellm (~40min, 2026-03), axios (~3h, 2026-04), lottie-player (~2h, 2024-10), ua-parser-js (~4h, 2021-10). A 7-day cooldown would have prevented every install. Worm-style attacks that spread fast across many maintainers (Shai-Hulud, TanStack) and long-dwell backdoors (xz, 5+ weeks) are explicit exceptions. Each ecosystem has its own knob: pnpm minimumReleaseAge, npm --min-release-age (11.10+), uv --exclude-newer, Renovate minimumReleaseAge, Dependabot cooldown.

Solution

Configure a minimum-release-age window (7-14 days) at both the package manager and the upgrade-bot. Verify the current syntax in each tool's docs, most of these knobs shipped in 2025-2026 and the exact key name has changed at least once per tool.
