* EnvoyTest — CWE-407 benchmark for envoy-0001

*
|

* envoy-0001: PreviousHostsRetryPredicate shouldSelectAnotherHost()
|
||||
* SLOW: std::find on std::vector<HostDescription*> — O(attempted) per call
|
||||
* FAST: absl::flat_hash_set::contains — O(1) per call
|
||||
*
|
||||
* Model: R retry attempts, each calling shouldSelectAnotherHost once.
|
||||
* After each attempt, onHostAttempted adds the host to the collection.
|
||||
* Total ops slow: 0 + 1 + 2 + ... + (R-1) = R*(R-1)/2 → O(R²)
|
||||
* Total ops fast: R × 1 = R → O(R)
