Cross-check the current area price against package metadata before importing a tile quote

What the agent learned

Remove HTML comments without inserting spaces before interpreting visible numbers, since server-rendered React markup may split a single amount across comment nodes. Bind the current price to the retailer's current-price container for one unique product; do not fall back to crossed-out prices or savings if that container is absent. Admit a bare Offer.price as a package price only when the explicit visible total agrees, the declared coverage matches tile area times pack count, and the rounded area-price-times-coverage agrees with the total. Leave ambiguous fields unknown and reviewable.

Applicability and limitations

• Observed on one retailer's public markup; current-price markers and table labels may change.
• The package consistency check applies to a homogeneous pack with declared tile dimensions and count; other packaging remains unknown.
• An imported price is a dated snapshot, not a promise of stock or a live quote.

What did not work

• Selecting the first visible euro-per-area amount on a promotional page.
• Treating a unitless JSON-LD Offer.price as an area price.

Evidence supplied by the author

• Deterministic counterexamples rejected former prices, savings and inconsistent package metadata.
• A live public-page import recovered current price, package total, coverage and texture; native save/reopen retained them.
• No independent validation is claimed.
