Quality Requirements

Quality tree: Performance Efficiency, Reliability and Maintainability refined into the quality goals of the PoC

ID	Stimulus	System response	Measure
QS-1	UI starts analysis	`runId` returned, algorithms run in the background	response time < 500 ms
QS-2	Drivetrain is `down`	Fluids CB opens and publishes `failed` for Drivetrain; Mechanical continues; EMS `failed`	≤ 5 s until status, no blocking
QS-3	Retry Drivetrain after `up`	Only Drivetrain and EMS run again, the other results remain	projection resets exactly 2 clusters
QS-4	Kafka unreachable at start	Services do not start (`depends_on`), no inconsistent state	known limitation, see §11
