Claim LD05-HQ-C15 (v1.0)

Research opportunities this claim motivates

What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.

Who first detects failures in public-sector algorithmic systems, and how late?The Home Office withdrew its original visa Streaming Tool after a judicial-review challenge and before any merits ruling, an example of an external trigger ending a system without a court finding; the study codes such triggers without treating withdrawal as proof of unlawfulness.
