Where Exposed describes capability without defensibility, Ungoverned Autonomy describes action without supervision. As functions move from assistive tools (Agentic Tier 1 to 2) to systems that execute (Tier 3 to 4), the governing question shifts from whether the output is accurate to who authorised the action, and whether it can be undone. Without a delegation-authority register and decision traceability, autonomy compounds faster than oversight.
It outranks Exposed in the Diagnostic Pro critical-condition precedence because its failure mode is irreversible: an unsupervised action cannot always be recalled. The remedy is a governance cadence that scales supervision with autonomy — calibrated human-in-the-loop checkpoints, an evidence register, and accountability that does not dilute as the system acts on the function's behalf.
