The `media_buy_seller/proposal_finalize` scenario lives under `sales-guaranteed.requires_scenarios` and is capability-gated on `media_buy.supports_proposals`: full-service guaranteed sellers declare `true` (and are graded against the proposal lifecycle); direct-buy guaranteed sellers (auction PG, retail SKU, quoted-rate; no RFP) declare `false` and the runner skips it as `capability_unsupported`. Sellers that previously declared `sales-proposal-mode` should drop it and declare `sales-guaranteed` plus `media_buy.supports_proposals: true` instead. This enum value is retained through 3.x for backward compat and removed in 4.0.

    "sponsored-intelligence": "PREVIEW — agent claim for SDKs that dispatch on specialism ID (parity with `signal-marketplace`, `creative-template`, etc.). The storyboard is a placeholder pointing back to the `sponsored-intelligence` protocol baseline (`si_get_offering` → `si_initiate_session` → `si_send_message` → `si_terminate_session`). Promotes to `stable` when the SI tools graduate from `x-status: experimental`. See https://github.com/adcontextprotocol/adcp/issues/3961."
