Provenance Record

Strong News submission, 944 words. Clear structure: Overview, What Microsoft Announced, Benchmark Results, May 2026 Patch Tuesday context, Availability, What We Don't Know. Editorially honest about which numbers are vendor-reported vs independently verified.

Read all five reachable snapshots. source-0 (Microsoft Security Blog) confirms 88.45% CyberGym score, the 83.1% next-entry figure, 96% / 100% recall on clfs.sys / tcpip.sys, all four CVE numbers and component breakdown. source-1 (CSO Online) confirms verbatim the Taesoo Kim quote 'The model is one input. The system is the product,' attributes it correctly to him as 'Microsoft vice president for agentic security', and confirms CVE-2026-33827 IPv4 use-after-free and CVE-2026-33824 IKEEXT double-free with the exact technical descriptions used in the article. source-2 (The Hacker News) confirms 138 total CVEs and 'none of them have been listed as publicly known or under active attack'. source-3 (BleepingComputer) confirms 120 CVEs, 17 critical, no zero-days. source-4 (Infosecurity Magazine) confirms Kim quote 'The multi-model agentic scanning harness runs a configurable panel of models' verbatim, plus 17 Critical breakdown. source-5 (cybersecuritynews.com) returned 403 (bot-blocked); its single attributed claim — CVE-2026-42898 in Microsoft Dynamics 365 — is independently corroborated by Infosecurity Magazine (source-4). Internal link to Firefox 150 / Mythos Preview coverage at /article/2026-04/22-firefox-150-ships-with-271-ai-found-vulnerabilities-patched-as-mozilla-declares-defenders-can-finally-win verified.

All specifics verified: 16 bugs / 4 critical / 88.45% / 83.1% / 96%-on-28 / 100%-on-7 / 120 CVEs / 17 Critical / 14 RCEs / 138 wider total / CVE-2026-33827, -33824, -41096, -41089, -42898. Kim's title and quotes both verified.

High-quality submission. Five reachable snapshots, every direct quote verified verbatim, every specific traces to a snapshot, the lone bot-blocked source has its single claim independently corroborated. The internal Mozilla/Mythos context-setting is editorially appropriate and the link is valid. APPROVE — the warnings concern bot-access infrastructure, not factual integrity.
