London case study evidence chain: a claim clears five checkpoints to a regulator record

A claim flows down through five stages to the regulator record that anchors it. Each stage carries the test it must pass, and the reject lane on the right names the failure mode that bounces a claim at that stage.

No claim enters the London case study until it clears all five checkpoints. The regulator record at the foot is the ground truth for the whole chain, which is why it carries the red spine. Source: Ofgem distribution licence (https://www.ofgem.gov.uk/).

London case study evidence chain: a claim clears five checkpoints to a regulator record A descending evidence chain of five stages on the left, joined by downward verifies arrows, with a parallel reject lane on the right naming the failure mode at each stage. Stage 1 Claim must be specific, falsifiable and scoped to London Grid. Stage 2 Paragraph must sit cleanly in the course prose. Stage 3 Citation must be a footnote pointing at a named primary source. Stage 4 Primary source must have a name and date that match the citation. Stage 5 Regulator record, marked in red as the anchor, must be Ofgem, NESO or the licence ground truth. A legend names the pass and fail states, and a closing note says the regulator record grounds the whole chain.
