U P D A T E : Problem solved. Turned out simple.
Was working on the extractor drawings in detail, calculating the claw dimensions, when it occurred to me: "Maybe the claw, the 'fang,' is simply too long. What if I just file down the 'fang' a touch and make it shorter? Then the extractor hump won't be pushed up as high and grind and bind against the extension teeth."
Took out the ol' Makita angle grinder with a metal grinding wheel, gripped an extractor in some pliers, and kinda touched the bottom of the extractor claw to it. Some tiny sparks flew. Soon the bottom of the extractor claw was a shiny silver — a little chewed up like a tiny chihuahua got after it — but it was, indeed, shorter.
Reassembled the bolt, installed it in a gun with my dummy firing pin, and hand-cycled a magazine: Slick, smooth action and a beautiful pile of cartridges. Hallelujah!
Now, how to "fix" 100 extractors on an industrial scale with perfect mechanical precision? Ain't gonna Billy-Bob angle grind 100 extractors. So that's the next problem....
