What a seller will guess or drop

56 in all: 5 stop the brief constructing, 1 are read here and travel in neither payload, 50 leave a field empty for the seller to fill however it likes.

Blocks — nothing ships

• blocks Advertiser identifier — Advertiser identifier is one of AAMP CampaignBrief's required values and no value reached the payload. The AAMP brief will not construct, so nothing downstream of the buyer agent runs.
• blocks Campaign name — Campaign name is one of AAMP CampaignBrief's required values and no value reached the payload. The AAMP brief will not construct, and on the AdCP side the campaign has no human-readable handle in any artefact the seller sees.
• blocks Campaign objective — Campaign objective is one of AAMP CampaignBrief's required values and no value reached the payload. The AAMP brief will not construct, and no downstream allocation logic knows whether to optimise for reach or for conversion.
• blocks Budget currency — Budget currency is one of AAMP CampaignBrief's required values and no value reached the payload. AAMP rejects the brief, and AdCP rejects `budget_range` entirely — `currency` is its only required key.
• blocks Budget split by channel — Budget split by channel is one of AAMP CampaignBrief's required values and no value reached the payload. The AAMP brief will not construct: `budget_pct` is required on every channel allocation, must be `0 < pct <= 100`, and the values must sum to 100.

Drops — read here, carried in neither payload

• drops Primary audience — Primary audience is stated in this brief and reaches neither payload. Documented as one of AAMP's nine required fields; in code `target_audience` is `AudiencePlan | None = Field(default=None)`, so the model constructs without it — required by docs, optional by code. On the AdCP side the value is a SignalRef, not a taxonomy ID, and it must be buyer-selectable on the product: `included_signals` and bundled provider signals explicitly do not satisfy `signal_targeting`. AAMP validates contextual refs against IAB Content Taxonomy 3.x and rejects pre-3.x IDs. The buy runs untargeted: AdCP returns run-of-network products, and AAMP treats a null plan as "no audience targeting".
