Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
dependencies unvetted-dep:es6-object-assign AI (dependencies): es6-object-assign is a well-known, straightforward polyfill appropriate for a browser-targeting assert module. ai
maintainer-change maintainer-added AI (maintainer-change): Large maintainer list is consistent with browserify org's known practice of adding community maintainers. Legitimate org transfer. ai
maintainer-change maintainer-removed AI (maintainer-change): shtylman removal is part of the documented transfer to the browserify organization; not indicative of a hostile takeover. ai
source-diff source-size-tripled AI (source-diff): Size increase explained by addition of Babel build pipeline producing transpiled output in build/ directory. No obfuscation or injected payloads. ai
provenance publisher-changed AI (provenance): Legitimate transfer to browserify org; lukechilds is a trusted publisher with strong track record. Repository matches browserify/commonjs-assert. ai
dependencies unvetted-dep:object-is AI (dependencies): object-is is a well-known ljharb-maintained polyfill; appropriate dependency for a browser assert module. No malicious history. ai
provenance no-provenance AI (provenance): Lack of provenance is common for this package's age and ecosystem; publisher is highly trusted with long track record. ai
dependencies unvetted-dep:is-nan AI (dependencies): is-nan is a well-known ljharb-maintained polyfill; appropriate dependency for a browser assert module. No malicious history. ai
