Anything you would do differently or could have saved some work looking back?
I would have liked to have a real "compactor". But you can't have every piece of eqpt that you wish for just hanging around. DIY can take months.
Finding a trucker to bring me SAND for fill, that concern reduced somewhat. (Free sand !, a little bit moist. and LOTS of it !)
Wish I had a 3rd pic (of the geotex folded over ontop.)
Tracked vehicle doesn't compact much, but it's moist sand, and its heavy.
I suppose it's weight compacts all the lift layers below.
Those form boards are 4x12 held vertical with #5 rebar stakes into the geotex lift below.
I have laser elevations "before", and will be able to measure settling of the top surface as time passes.
What I most needed, and wasn't able to get, was confirmation that a stacked block wall leaning against a Geotex retaining wall was..... "no worries of soil pressure against the block wall".
(re: Civil Engineer member Sam Wise, see post
Who knows about stacked-block retaining walls?) who wrote that the stacked block wall was a decorative facing for the (geotextile) retaining wall.
If that's the case.....
and I tend to believe it

then there's almost no pressure on my stacked blocks.
Anyway, I had to press on, with advice from just one TBN engineer who told me what I wanted to hear and of course it was a sweet sound...
Any more civil engineers willing to opine......?
Is the block wall subject to soil pressure from the geotextile reinforced embankment?
The 5/8clean gravel and the topsoil heap doesn't look like 'much'.
The block mfr approves 42" max (without reinforcement).
