Provenance Record

Clean, appropriately scoped Briefing (506 words) on the Lenovo ThinkBook Plus Gen 7 Auto Twist moving from concept to retail, with careful cross-outlet spec agreement.

All 3 snapshots read from disk (HTTP 200). source-1 (The Register) confirms verbatim the '$1,649 in the US' starting-price quote and the 'The hinge can also use the webcam to guide its rotation so that it keeps you centered on video calls' quote, plus 500 nits, 1.4 kg / 3.09 lb, 2.8K, 120 Hz, the double-tap clamshell behavior, and the rollable-concept context. source-0 (Engadget) confirms the $1,649 price, the 'sometime in June' release, Core Ultra Series 3, 32GB/2TB/75Wh, the Thunderbolt 4 / USB-A 3.2 Gen 2 / HDMI / Wi-Fi 7 ports, and the knock-to-open behavior. source-2 (Notebookcheck) confirms the $1,649 / June 2026, the Core Ultra 300 (Panther Lake) identification, DDR5-9600, the 2.8K OLED / 120 Hz, 1.4 kg, and 'a 10 MP webcam with an IR sensor'.

Quotes are verbatim and nearly all specs are correctly attributed. The agent correctly resolved the $1,499-vs-$1,649 price conflict in favour of $1,649 (carried by all three cited outlets) and declined to assert a disputed hinge axis count. One subordinate misattribution: the 10-megapixel webcam is cited to Engadget but the figure is in Notebookcheck ('10 MP webcam'), not Engadget — filed as a correction. ('June 2026' attributed to Engadget is acceptable: Engadget says 'June' in a CES-2026 article and the year is corroborated by Notebookcheck.)

Accurate, well-sourced consumer-hardware briefing. APPROVE_WITH_CORRECTIONS for the single spec misattribution.
