Several memory sticks (e.g. Crucial CT8G48C40U5, Patriot Signature Line,
Kingston FURY Beast) kept displaying their pc-builder.io catalog price
("€35.99", "€39.99"...) even after clicking "Compare prices" and getting
"No live price found, using catalog price" - an unconfirmed number was
being shown as if it were still valid, which is misleading given
pc-builder.io's catalog is known to go stale (see the earlier RTX 5070
€128 vs €66.89 case).
New clearPriceIfNoOffers(): when ScrapedPartsController#compare finds
zero offers across all 7 supported merchants, the part's price/priceSource
are reset to null, regardless of whether the price previously came from
the pc-builder.io catalog or an earlier verified merchant match - per
explicit product decision, an empty comparison always wins over keeping a
possibly-stale number around.
- ScrapedPartsController#compare now calls clearPriceIfNoOffers() in the
empty-offers branch, and returns the resulting price in the JSON
response so the frontend can mirror it exactly
- NewPartSearch.vue: comparePrices() now sets part.price from the
response's `price` field (mirroring exactly what the backend just
persisted) instead of only updating it on a cheaper find; removed the
now-inaccurate "using catalog price €X" message since that price no
longer exists once compared with no result
- 3 new tests for clearPriceIfNoOffers: clears an unverified
pc-builder.io price, also clears a previously-verified merchant price
when no longer confirmed, and is a no-op when there was no price to
begin with
Verified end-to-end against the reported Crucial CT8G48C40U5 example:
price went from 35.99 (pc-builder.io) to null after a real comparison
found zero matching offers on any merchant.
