How a seller honors a given action on a media buy. Buyers branch on this to decide whether to expect a synchronous response, an automatic-with-fallback flow, or an asynchronous human approval. The mode is declared on each entry of allowed_actions[] (product, as modes[] array) or available_actions[] (buy, as singular mode). Requotes that fall outside the current buy envelope are not an action mode in 3.1; sellers return REQUOTE_REQUIRED from update_media_buy instead. Buyer SDKs MUST tolerate unknown future values by treating the affected action as unavailable until they re-fetch the product or buy and inspect the current available_actions[] / allowed_actions[] metadata.
