Field reports built the same way each time: collect what practitioners published, read every post, pull the numbers out, then check each one against the source that first published it. What fails the check is listed, not quietly dropped.
What the 2025 season actually did, how the 2026 calendar and the AI discovery layer change the plan, the discount arithmetic, a week-by-week checklist, five workflows end to end — and the circulating numbers that do not survive a look at the source.
What agentic commerce actually asks of a merchant: the three trades the one phrase covers, what UCP, ACP and AP2 want you to publish, what each platform shipped and what it cost them, and what a seller should do about it now — including what to refuse.
AI stage by stage down the ecommerce funnel: discovery moving into the answer and then into the feed, what Shopify switched on for merchants, how operators actually run AI-UGC and CRO work, and the funnel claims where the evidence runs thin.
