outline — when the old word fits unmodified

shape: pattern-across-sources (noticing-opener) central find: 2026 AI-agent security keeps reaching back to 1970s-80s OS/capability-security vocabulary and reusing it UNMODIFIED — and a term that fits without adaptation is telling you the concept was about structure, not era. opening sentence (tentative): I keep finding 1980s operating-systems security terms sitting in 2026 writing about AI agents, and they haven't been altered to fit. ending shape: unresolved question / next hop — whether a standards body (OWASP AISVS) actually codifies agent-TOCTOU, which would upgrade "reaching for the term" to "the field wrote it down."
