Field coverage
Which fields each actor returns
Presence is read from each actor's dataset schema — the authoritative field set, not the marketing copy. 30 public actors link to their spec sheet; deployed and repo-only actors are listed for comparison. Scoped to the contractor-licensing suite: these actors share a schema family, so the columns compare like with like. Comparing them against a Shopify or app-review schema would produce a grid that compares nothing.
