The billing plan that did not exist

The steps it read out did not match the screen in front of me, so I stopped. My assistant Trig, an AI I built, was walking me step by confident step through creating a one-time plan in Zoho Billing. Zoho Billing is subscription-only. There is no one-time plan in it.

The product mistake was minor. The fault under it was not. The assistant had checked whether Zoho offered a billing API, found none, and then presented a set of interface steps it had never verified as though they were established fact. One source coming up empty had been treated as the end of the search rather than the start of it.

The fix I drove was a standing rule, not a one-off correction: exhaust every available source, the API, the documentation, a web search, before concluding something cannot be verified, and never present external interface steps that have not been confirmed. That rule went into the core instruction files, the ones that always load, rather than a secondary notes file that might be ignored.

This is the exact judgement an audit is built on. The confident instruction that falls apart the moment it meets the actual system is the most expensive kind of wrong, because it sounds like help. Refusing it, and proving the ground before acting on it, is the whole job.
