All 36 KB of code was read in full and contains no outbound network sink of any kind — no fetch to an external origin, no XHR, sendBeacon, WebSocket, or hardcoded remote URL — and no dynamic code execution (no eval, Function(), atob, or script injection). The sole fetch monkeypatch (:344-457) intercepts only GET responses to ChatGPT's / and Claude's /, trims the message tree locally via trim() (), and hands the shortened body back to the page — exactly the advertised 'trim rendered messages' behaviour, with zero copy of conversation content leaving the tab. The permhash cluster (6% flagged across 23,621 generic storage+activeTab peers) and the chrome-stats score are weak base-rate signals that corroborate nothing at the code level, while publisher reputation ( malicious, valid domain email) and CWS-disclosed collection of 'none' match the code. The [IoC] MalExt Sentry note from 2026-03-09 (added ~12 days after listing creation, consistent with an automated new-listing sweep) is directly contradicted by this version's source. The bundled manifest adds [domain withheld] over the published summary, but that is a scope *increase toward* the stated product (the name, description, and trimClaude code path all cover Claude) rather than a covert delayed expansion — the live listing has fewer hosts, not more — so it is noted here rather than logged as a finding.
