JavaScript analysis reported javascript.xray.shady-link
Expected behavior · high confidence
The automated scanner mistook a safety check for a suspicious link. The extension checks whether a saved avatar was stored as an embedded image reference, which can happen as a leftover from an older version of the extension, and if so swaps it for the app's standard local avatar URL. Nothing is downloaded from or sent to any website because of this code; it is documented cleanup logic for the avatar feature.
Technical evidence
Scanner reason: JavaScript analysis matched static JavaScript security signal javascript.xray.shady-link. The match applies to this repository.
Contextual assessment: The static analyzer's link heuristic matched data-URI-scheme string literals; the cited line is a prefix membership test on a saved avatar reference, not a fetched or constructed link. The surrounding routine detects inline data-URI avatar values that a previous build of this extension wrote into chat message records, resolves the owning persona through an index built solely from the extension's own stored uploads, and rewrites the reference to the host application's canonical same-origin thumbnail URL, blanking values it cannot resolve. The second occurrence of the same signal is the analogous guard in the avatar load-failure repair hook, which skips repair handling for inline references. These checks initiate no network activity: an inline data-URI in an image source cannot produce a request, and the only URLs written back are host-local thumbnail paths derived from the extension's own configuration. The behavior matches the extension's documented self-healing and embedded-storage fallback features, involves no credentials, remote destinations, obfuscation, or undeclared persistence, and stays proportionate to the stated purpose of managing and displaying persona avatars.
