Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection shows a browser-oriented Bloom player with audio/activity assets and bundled frontend libraries, with no install-time execution, shell/native loading, credential harvesting, or AI-agent control-surface mutation. Scanner hits map to benign bundled code, valid media assets, and package-aligned browser resource loading. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-07-09T23:25:46.054Z - **Finished:** 2026-07-09T23:27:01.206Z - **Download time:** 510 ms - **Static scan time:** 1569 ms - **AI review time:** 73072 ms - **Total time:** 75152 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was established. Runtime behavior is a browser Bloom book/player that loads book content, audio, fonts, and package-aligned analytics/resources when used. - **Trigger:** user imports library or opens dist/bloomplayer.htm in a browser/WebView - **Impact:** normal Bloom book rendering and audio/activity playback - **Evidence paths:** package.json, src/shared/narration.ts, src/shared/dragActivityRuntime.ts, lib/shared.es.js, dist/bloomPlayer.CzxSC7ao.js, dist/right\_answer-XEe3HakR.mp3, dist/wrong\_answer-BhCi5k6f.mp3 - **Review source:** ai\_review - **Reviewed:** 2026-07-09T23:27:01.206Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** browser DOM/audio player and bundled UI code - **Rationale:** Static inspection shows a browser-oriented Bloom player with audio/activity assets and bundled frontend libraries, with no install-time execution, shell/native loading, credential harvesting, or AI-agent control-surface mutation. Scanner hits map to benign bundled code, valid media assets, and package-aligned browser resource loading. - **Network endpoints:** https://bloomlibrary.org/analytics.dev.min.js, https://bloomlibrary.org/analytics.min.js, https://bloomlibrary.org/analytics.test.min.js, https://bloomlibrary.org/fonts/Andika%20New%20Basic/AndikaNewBasic-B.woff, https://bloomlibrary.org/fonts/Andika/Andika-Regular.woff, https://cdnjs.cloudflare.com/ajax/libs/slider-pro/1.3.0/css/images/openhand.cur ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json has no lifecycle scripts or bin; export is lib/shared.es.js., src/shared/narration.ts only creates/loads audio elements from urlPrefix()/audio/\.mp3 for Bloom playback., src/shared/dragActivityRuntime.ts uses bundled MP3 defaults and page attributes for activity sounds; no shell or filesystem APIs., Bidi/invisible Unicode scan over package source returned no matches despite scanner hint., MP3 files are valid MPEG audio assets, not executable payloads., Network URLs in dist are Bloom/player docs, fonts, analytics, and bundled library references; no credential harvesting or exfiltration code found. ## Affected versions and remediation This report applies to bloom-player@2.20.1. - Review the evidence and your use of bloom-player@2.20.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
