The signature question of dependency due diligence. Columns: npm downloads per month (attention). Line: merged pull requests per month (delivery). 12 full months.
Reading: npm downloads grew 3.5× over 24 months while delivery held at ~87 merged PRs/mo. Divergence risk — attention keeps climbing while shipping slows; hype is outpacing maintenance capacity.
Star-velocity anomalies cross-referenced with Hacker News, Reddit and release events.

verified via author historyVerdict: tough room for newcomers — only 48% of verified first-time PRs got a maintainer-class response and 0% merged (window 2026-03-24..2026-06-22). The core team ships fast, but drive-by PRs mostly sit open.

Verdict: moderate key-person risk. 61 human commit authors in 12 months; top author (Rich-Harris) holds 37.5%, top 3 hold 69.3%, 12 authors above 1% each.

sveltejs/svelte is upstream — no successor needed (project active). Top forks by stars are all stale (pushes >1y ago). Successor detection activates if the repo goes dormant.
If this repo goes dormant, this section becomes “Where did development continue?” — with evidence labels per fork.

svelte@5.57.1, 2 days ago. Median gap between stable releases is 1.7 days; 9 stable releases shipped in the last 90 days.
On the evidence: yes. 4.2M npm downloads/week, 903 dependents on the default version, 61 human authors, 0 advisories on the current default, no fork-succession pressure. Caveat for contributors: the newcomer funnel is weak (0% first-PR merge rate).
