HCD.13:5.2 - A failed source link changes the arrangement result

During an additional constructed source-dependent task, the required technical source is inaccessible. The earlier qualified contribution depended on using that source. The assessor can verify the access failure directly.

Return source access to the responsible provider and leave the dependent performance judgement incomplete. There is no reason to run a memory-loss diagnosis to explain a known missing input. If a later restored-access attempt is observed, report it under the restored condition without retroactively completing the interrupted attempt.
