"Around 0" when activated is good. "1 at rest" is not. Do you have your meter on the correct (low-ohms) scale? At rest, the meter reading should be "open circuit", "infinite", or "out of range". "1 ohm" makes no sense, 1 megohm might.

The solenoid clicks once, but the power to it is constant as long as the gas pedal is pushed far enough to activate the switch.

Seems reasonable. Still not sure of your switch adjustment.

I wouldn't call it the "front receptacle". It's the vertical leg of the "T" made by the two blades on the trans connector.

The only time it ratchets is to set the adjustment. After that, no ratchet until you set initial position again.

The switch cannot be adjusted for part-throttle shifts. That is, you can set it most anywhere you want...but the first time you fully depress the throttle, it's going to ratchet into proper position where it kicks-down at "near" full-throttle.

The photo is not helping me visualize what's happening. Blurry, sideways, doesn't show the gas pedal rod vs. the post on the switch.

If the ratchet is worn-out, the switch will not hold adjustment. That's possible, but rare.

Leave the gas pedal in the idle position. Depress the lil' lock-tab on the switch plunger, and move the plunger OPPOSITE the direction that the gas pedal rod moves the post/switch plunger. I bet you'll hear and feel the ratchet.

When the post on the side of the plunger is closer to the gas pedal rod, cram the pedal to the carpet. You'll again hear the switch ratchet into position. The switch has self-adjusted to correct position.

Done.
[Edit] Found a photo of the pedal vs. switch; I was mistaken. The switch moves opposite the way I thought it did. The service manual illustration you posted is correct--but--are you depressing the lock-tab to move the plunger FULLY to the end of it's travel? Then mat the gas pedal, you should hear it ratchet.
