Read-only preferred no clones/sharing/instances/unrelated edits. Check owner UID latest version URL,pins names/types/count/distinct mapping,actual copper geometry axes/pitch/span/min gaps/no overlaps,topview marker,parametric assetless model node/body/fit limits. Nominal not maximum envelope renderer omission not absence. Compact pass/fail/unverified report. Only publish existing corrected new version for genuine repair.

Thought for 14 sec
I’ll verify the published pin mapping, copper geometry, and parametric model without changing the part.

jharwinbarrozo, UID c565ceb6-9832-48f3-806d-fa6a5eabb348, latest version e70f76e2-323c-4e10-8eed-af3cbf76d612; six distinct pads map correctly to 1 LX Passive, 2 GND Ground, 3 FB Input, 4 EN Input, 5 OUT Input (sense—not power output), 6 VCC Power In.PASS, geometry only: Rotated copper is 1.00 mm X × 0.70 mm Y, centers X = ±1.30 mm, Y = +0.95/0/−0.95 mm; pitch 0.95 mm, row-center span 2.60 mm, overall copper span 3.60 × 2.60 mm, minimum gap 0.25 mm, opposing-row gap 1.60 mm, no overlaps, and rendered top-view marker beside pin 1.
UNVERIFIED / not manufacturing-qualified: Recommended land-row endpoints remain unresolved; an active assetless parametric Model node exists with nominal body 1.60 × 2.92 × 1.175 mm, but maximum-envelope fit and detailed lead geometry are not qualified—renderer omission would not establish model absence; no edits or publication performed.
