Notes
- Active listings and historical observations are source-grounded. Dashed monthly values are provider-modeled estimates, not observed listings or transactions.
- Modeled estimates cover the current month and previous 12 months and require a grounded observation from the same provider.
- Prices are USD per single item and exclude shipping and tax.
- Broad mixed product family was represented using disclosed-quantity Apple extension-cable lots and a used MagSafe adapter-and-cord set; exact variants are preserved in titles and notes.
- No ask was below one-third or above three times the initial USD 22.99 median, so all three were retained for the anchor.
- openai validation accepted 16 of 16 raw points.
- Requested identity is a mixed bulk lot of used/untested Apple MacBook power adapters, extension cords, and cables with undisclosed unit count; lot-level and undisclosed-quantity prices are excluded, so the anchor represents one representative single used Apple MacBook power adapter, not the lot.
- Three current-listing queries were used (85W MagSafe 2, refurbished MacBook chargers, 60W MagSafe 2 A1435). Only one candidate met all qualification rules; the stopping target of three canonical item URLs across two domains was not reached.
- Excluded candidates: eBay aggregate/product-catalog and search pages (category/price-comparison, not direct item pages); ended listing 187251384766; sold listing 256786512807; item 403384729807 and 365302231533 (no grounded per-unit USD ask visible); Back Market and Amazon pages (no grounded per-unit USD price in results); multi-unit listings such as 2x A1424 bundles.
- The optional fourth query was left unused because no direct archive or price-history source with exact dated per-unit used asking prices was identified; a flat modeled fallback was applied accordingly.
- Low confidence: single comparable, and the accepted listing is a UK-located seller with a converted USD figure. The subject lot is used/untested mixed-generation stock, which typically trades well below tested-working single-adapter asks; per-unit value for untested stock should be treated as a ceiling, not an expected realization.
- anthropic validation accepted 14 of 14 raw points.
- Target query specified a bulk lot; per instructions, unquantified lots are excluded in favor of representative single genuine Apple MacBook power adapter units.
- gemini validation accepted 16 of 16 raw points.
