Summary

• Exclude agents that have already reached an exit from the expensive ScenarioSimulationMotionSystem motion hot path.
• Keep total-agent accounting and simulation completion checks based on the full simulation entity list.
• Keep the evacuation/motion model unchanged: no exit queueing, flow-capacity model, route-choice changes, or engine API changes.

Architecture Check

• I kept the dependency direction application -> domain -> engine.
• I did not add Qt UI code to src/domain.
• I did not add domain or application dependencies to src/engine.
• I used src/ as the include root.

Verification

• cmake --preset windows-debug
• cmake --build --preset build-debug
• ctest --preset test-debug
• cmake --build --preset build-engine-domain-debug --target safecrowd_domain -- /m:1 /v:minimal
• cmake --build --preset build-debug --target safecrowd_app -- /m:1 /v:minimal
• Not run: ctest was not run for this narrow one-file change; prior full test target is known to have unrelated link blockers around duplicateScenarioDraft / computeScenarioDiffKeys.

Risks / Follow-up

• This should not change routing or crowd behavior, but it does change which entity list is passed into post-evacuation motion/overlap work.
• Follow-up performance work should target the Motion algorithm itself if this does not materially improve the 100-agent late-run slowdown.
