The validator unit tests now cover 0, 1, and NaN, but the higher-level CLI tests still only exercise -1, 2, and 1.3. Since this bug escaped through the real flag path in pkg/clusterautoscaler/flags.go, please add at least one command/e2e case that proves the CLI rejects 0 or 1 end-to-end.
There was a problem hiding this comment.
While looking at adding the boundary cases, I noticed that the utilization-threshold entries for "-1" and "2" in the validation maps produce identical fmt.Sprintf output (same error string). In Go map literals, wouldn't duplicate keys mean only the last entry survives? If so, only "2" would actually be tested and "-1" would be silently dropped — is that intentional, or is there something else I'm missing about how these maps are consumed?
If it is a duplicate key issue, swapping the existing values to "0" and "1" would cover the new boundary behavior — though it's worth noting that only one of the two would actually be exercised. A follow-up PR could restructure the maps (e.g., invert so the input is the key) to ensure all cases run.

These look like real e2e hardening issues, but they’re outside the changed hunk and not introduced by this utilization-threshold fix. I wouldn’t block this PR on them; they’re better handled in a focused follow-up against |

Summary
PercentageValidatorbounds to match the cluster-autoscaler-operator webhook and OCP documentationnumber < 0tonumber <= 0andnumber > 1tonumber >= 1— value must be strictly between 0 and 1Context
The ROSA CLI accepted
--scale-down-utilization-threshold 0, storing"0.000000"in OCM. The cluster-autoscaler-operator's validating admission webhook rejects this value, causing Hive to enter a permanent patch rejection loop and blocking cluster upgrades.The OCP 4.18 documentation states the value "must be a value greater than 0 but less than 1." Additionally, setting the threshold to 0 silently disables scale-down in the upstream Kubernetes autoscaler (kubernetes/autoscaler#2221).
