This is a research-status note. No matching solution was found in the checked messages, so the root cause and solve method remain unverified.
Search coverage: server-wide exact-name searches for MCCRAB3 (6 results), MESHGATE (4 results), and LARPIN2 (6 results), plus the visible 2026 discussion in #web and #writeups. This does not prove that no solution exists in unindexed attachments, differently named messages, private threads, or elsewhere. Counts are a snapshot.
