Every network sink in the three JavaScript files provided is first-party: six ` /*` and ` /*` endpoints on [domain withheld] (:9818, 9842, 9867, 9935, 10016, 10069), one Google OAuth token-revoke call (:9893), and one `get-transaction` call in price.:1969 — nothing else, confirmed by enumerating all 11 `fetch(` sites. The media-download core in only ranged-GETs same-origin `[domain withheld] URLs it builds from Telegram's own `window.rootScope.managers.appMessagesManager` document locations (lines ~330-360) and saves them through a blob anchor (line ~520) — media bytes never leave the browser, so the ML `critical` score and the 6%-flagged permhash cluster are not corroborated by any code here. On the mandatory manifest cross-check: the bundled 2.0.10 manifest is a superset of the published summary (`identity`, `activeTab`, `[domain withheld], `[domain withheld]), which is exactly the delayed-malicious shape given the one recorded hand-off — but each addition maps to visible, benign code (`identity` → `launchWebAuthFlow` with scope `openid email` at:9801-9815; `[domain withheld]` → the revoke fetch at 9893; `[domain withheld]` → the licensing API and the ` ` web-accessible resource), and the bundled manifest actually *narrows* the published `<all_urls>` / `"*"` web-accessible-resource grant to two specific origins, so I read this as listing-snapshot lag on an extension updated 3 days ago rather than escalation. Confidence is capped at medium because three declared files are absent from the bundle — ` ` (the only privileged code that actually runs on [domain withheld]), ` `, and ` ` — against ML metadata citing 86 files and 5.9 MB of JS, so a backdoor in the content script cannot be ruled out. Two hygiene notes that are not findings: module `9b11` grants 24 hours of unlimited downloads in exchange for a store rating (incentivized reviews), so the,833-review score and chrome-stats' `good-user-rating` are weak corroboration; and `resolveAndDownload` will fetch a non-Telegram URL handed to it via the page-world `video_download` CustomEvent if DOM resolution fails, which is sloppy but only reaches page-origin fetch plus a user-visible download.
