When to use

Before betting the repo, a project, or a client on a tool, method, or principle.

What it does

1. 30 days: rank by observed engagement — releases, stars, pushes, dated announcements. Freshest verified signal wins; reputation counts for nothing.
2. 30 years: rank by survival — still-used + built-upon + hype-survived (the 3-probe test). Tier 🏛/🌳/🌱; under-10-years can never outrank a survivor.
3. 300 years: rank by endurance with a Whig-history guard — keep the surviving kernel, flag the superseded dogma (Modulor's ruler, not his city).
4. Synthesize the Lindy read: bet interfaces on survivors, hot-swap the young layer, and record the anti-portfolio (who was louder and died).
