## Security analysis

### Published attack-surface review

- **Summary:** No attack surface was identified in the inspected package source. The flagged bundle patterns correspond to player analytics, language metadata and a global-object compatibility fallback.

- **Trigger:** The player loads analytics during normal browser use unless independent mode is disabled, and records reading events.

- **Impact:** No malicious effect was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T23:08:16.794Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Analytics use the Bloom Library endpoint; the inspected code shows no unrelated credential transfer or install-time behavior.

- **Rationale:** The manifest has no lifecycle hooks and points to the shared player library. The flagged bundle constructs and metadata are consistent with normal player behavior; no malicious behavior was identified.

- **Files touched:** package.json, lib/shared.es.js, dist/bloomPlayer.8sVNsg8A.js

- **Network endpoints:** bloomlibrary.org

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exports the shared library and contains no lifecycle script declarations., The shared library exports player functions for audio, narration, scrolling and activity cleanup., The bundle loads analytics from bloomlibrary.org and tracks player reading events., The flagged directional mark appears in a language-name entry., The flagged Function call is a fallback to obtain the global object.
