Traditional SLAs (uptime, p95 latency, error rate) are structurally insufficient for autonomous agentic-AI; the four metrics that actually work are action-bounded availability, MTTD-for-Agents, output-distribution drift, and per-class action error budget, and vendors that cannot expose the telemetry these require are not yet production-ready against the 2026 enterprise procurement bar.

60-day cadence covers the OpenTelemetry GenAI semantic-conventions stable-promotion follow-on plus the EU AI Act Article 9/Article 17 enforcement window opening 2 Aug 2026. Three review checks: a major-vendor SLA release that commits to action-correctness or output-distribution stability contractually (not just as telemetry); a standards-body publication defining agent SLA primitives explicitly; a regulator enforcement action where an inadequate agent-layer SLA was the in-scope finding.
