Yehiel Amor claims his released provenance-gate gateway stopped 99.3% of 609 hijacked AgentDojo attacks — unmoved by backwards/base64/Unicode-tag/German obfuscation because it never reads injected text, only tracks where each tool-call control value came from — where three open prompt-injection classifiers caught far less while flagging up to 72% of legitimate tasks, and independent adoption or replication would establish deterministic provenance gating as a workable replacement for injection classifiers, bounded by his own reported 28.9% legitimate-task approval friction and 53–66% stop rate under a poisoned counterparty graph.

Independent testing will determine whether Vercel Labs' Deepsec can reliably detect prompt injection and unsafe tool calls in autonomous coding-agent workflows without excessive false positives.

ApolloRaines claims jBlaze weight surgery bakes a permanent EchoLeak (CVE-2025-32711-class) prompt-injection defense into released Llama-3.1-8B weights — 100/100 canary defense at F16, 42% leak reduction on the harder role-based benchmark, with reasoning and calibration unchanged — and independent red-teaming of the published weights would establish weights-level immunization as a practical injection defense.
