List Instagram ad identities

Discovers identities through connected_instagram_accounts, Page linkage and Page-backed identities, with a best-effort business fallback. Business permission errors do not fail discovery. The resolved object uses the same profile-scoped resolver as ad creation; null means no identity was resolved. Format-specific observed-actor fallbacks at creative creation are not predicted.

A/B tests and lift studies

Lists the ad account's A/B tests and lift studies (Meta's `/act_X/ad_studies`), rows returned verbatim. The default projection covers id, name, type, timing and cells with split percentages; `fields` is a raw-passthrough override.

List advertisable apps

Lists applications available to a Meta ad account, their supported platforms and unmodified object store URLs. A listed app still needs a configured mobile platform and store URL to run install promotion.
