+**[@mention + assignment]** — [SIGKILL String.hashedSuffixRange (WKNavigationAction.isSameDocumentNavigation main-thread stall)](https://app.asana.com/0/0/1215403820548743) — Jacek at 17:54+06 (11:54 UTC)
+Context: Jacek assigned this Sentry crash task to you and asked: "I see your name being mentioned in blame around the code, could you please take a look at it and reassign if it's not yours?" The task has detailed RCA notes (main-thread stall on `hashedSuffixRange` / `StringExtension.swift:67` for large `data:` URLs). Due Jun 12. No response from you yet.
+Action: Reply to Jacek — confirm ownership or reassign. If keeping it, scope a fix (the task already has a fix sketch).
