Overlays

An overlay is how you say something about somebody else's API contract without editing it. API Evangelist is a second author on 2299 providers' documents, and this is where that stays legible.

Where the actions land

447 distinct JSONPath targets. $.info dominates, which is the right place for a second author to write — metadata beside the document's own metadata, rather than inside the operations a provider defined.

The vocabulary they inject

3051 distinct x- keys across the corpus — the largest coherent extension vocabulary in the catalog, and one that has never been documented in one place. That is an authoring backlog, and it is ours.
