KS4 has no standalone published National Curriculum document. At KS4, what counts as the curriculum is essentially the awarding-body specs in aggregate. Rather than authoring a synthetic KS4 NC from scratch, the vault treats canonical KS4 nodes as frames defined by the union of overlays that point at them.

A canonical KS4 English Reading node, for example, names the broad area of learning in plain English (“comprehension of unseen non-fiction texts, including 19th–21st century literary prose”) and surfaces the overlay outcomes that test it — Edexcel IGCSE 4EA1 AO1, AQA GCSE English Language AO1, Pearson Edexcel FS English L2 R1 — with wikilink annotations showing which overlay tests what.

The result is navigable two ways: top-down (here’s an area of KS4 English; here’s how each overlay approaches it) and bottom-up (here’s an Edexcel spec point; here’s the canonical area; here are the AQA and FS equivalents). What learning is at KS4 becomes the consensus across overlays, made visible.
