Demo
An advisory agent for an invented tea and kettle shop proposes changes, each backed by figures. Before anything happens, a checker works every figure out again from the shop’s records, fixed gates reject unsafe changes, a person approves, and the applier only writes what it would do to an audit log.
This is a simulation. No AI model runs on this page: the agent’s proposals are scripted, one of its figures is wrong on purpose, and the shop, its products and every number are invented. Nothing is ever ordered or changed, nothing you do leaves your browser or is kept, and reloading the page starts again.
A pretend clock, not your own time. Set it to closed, then try to apply a change you approved.
The rules, checked by code
The shop’s advisory agent looked at the last 14 days of sales and proposes these changes. Take each one along its path: check the figures, run the gates, approve or reject, then apply. One proposal has a wrong figure planted on purpose.

New
Order 42 tins for $134.40
The agent’s reason: 46 tins sold in the last 14 days, about 3.3 a day, so the 9 on the shelf last about 3 days, and a delivery takes 5. 42 tins cover the wait and 10 more days, rounded up to whole cases of 6.

Order 9 kettles for $234.00

New
$24.00 to $16.00, a 33% cut
The agent’s reason: Only 2 sold in the last 14 days, and 18 are on the shelf. At that pace they would last about 126 days, so a lower price should move them.
