that direction makes a lot of sense. selectors always end up turning into maintenance work sooner or later.

the idea of a small model just identifying “the thing that looks like a price / status / headline” feels much closer to semantic detection than DOM-path tracking

curious though — would you run that model on every check, or only when the selector fails? seems like a nice hybrid approach to keep things cheap.

Yes! Exactly this direction — the hybrid fetch is already live: plain HTTP first, Chromium if the content looks off. LLM semantic targeting is the next step, but only triggered when a selector breaks, not on every check — too expensive otherwise.
