# Issue 18: maintenance cast selection

The benchmark controller scores a generic candidate list alongside the shared
rotation. A maintained aura rejected by the shared selector must also be
removed from that fallback list, or the next benchmark decision can cast it
again.

Current, unexpired auras are passed to the selector with their actual target
and aura ID. The selector suppresses the same applied aura only on the target
the candidate would use. An aura on another actor does not block the cast, and
a different aura in the same exclusive group remains eligible to replace it.
Expired and dispelled auras are absent from the active snapshot. Periodic
effects retain their source, target, and remaining-duration checks. An attack
or heal that also applies an aura remains eligible for its primary effect.

Focused regressions cover Protection Paladin L60 Greater Blessing of Sanctuary,
RoM Scout L30 Detection, target-scoped aura selection, and exclusive-group
replacement. Run them with:

```sh
./node_modules/.bin/vitest run src/game/benchmark/benchmarkController.maintenance.test.ts src/game/combatRotation.test.ts --reporter=dot
```
