Every entry carries provenance, an install-risk model and an evidence-based trust score. Top packages are deep-scanned against the 29 Sentinel security rules — we publish the raw findings. That is the difference vs popularity-scored directories.
10 documented checks per entry: unique id/slug, resolvable provenance, consistent install-risk model (npx/uvx = red, source/remote = yellow, verified chain = green) and scoring bounds. Live report: /api/certification.
The shipped registry tarball (shasum-verified) is scanned with the 29 MarketNow rules in tarball mode — including dist/, the code that actually runs. Raw findings published: certification-scans.json.
Tiers: core = evidence-gated (adoption, verification or age) · community = indexed with weak signal (trust capped at 55) · tracker = inventory of the wider ecosystem (no trust claims — names observed in public directories, deduplicated against our certified core).
