As you can see, when I export, the adjustements are not exported...
Your Layers panel shows you have set the opacity of the Gaussian Blur to 0%. That needs to be 100%, as it is in the file I provided.

This one looks fantastic! thank you, but I still have the same problem. When I export it is exported without the filters
The image I posted alongside an Affinity document is a PNG export from that Affinity document, so I cannot understand why an export does not work correctly for you.

There is no value field to go along with the + sign, unless it is the field that follows it, which is in % not degrees.
It is that value in the field to the immediate right of the "+". That has tooltip "Set the angle of the partial turn of the spiral" and the value is in degrees in the macOS app.

I just noticed you have the type set to decay, this + does nothing there.
The partial turn angle is effective for all of the spiral styles, but minimum radius of the decaying style needs to be small enough to allow all turns and the partial turn to be drawn.

The Boolean geometry Subtract command still has no option to create open paths when punching a region out of an object. However, the Shape Builder tool of v2 may give you a slightly faster workflow than you had in v1. See attached video.

The firstdefence selection method gives a selection intensity of the maximum of R, G and B for each pixel. I wouldn't use that method because it can result in a perceptually dark colour being considered as having greater intensity than a perceptually bright colour.
The smadell selection method gives a selection intensity of the perceived brightness (maybe luminosity or maybe luminance or maybe luma or some such measure of "brightness") for each pixel.

Just wondering if it's possible if the pattern layer is already in place with some content in it?
Yes, position any object above the master tile of the Pattern and then use Merge Down command to incorporate into the Pattern.

The group transformation error has something to do with Artboard location in the document space.
If you first rearrange the Artboards so 'Task Details' has its origin at top left of all, then the subsequent grouping will be performed correctly.
That is proposed as a workaround to help get your project finished. There is a bug to be fixed by the developers.

Ok I duplicated your existing Spiral in Artboard1 in your sample file, and input the formula as specified (no quotes and 45 for the cos value) into the Decay% field and I get something very different (in green) and gives me a decay of 29.28% ...?
You've used the per-turn decay option. I told you to use the per-segment decay option and the "1 - cos(a)" expression.

Got it... and how did u figure out the "Decay Ratio" to be 93.75%?
93.75% is the decay of the radius for one turn of a 4-gon spiral only. It's different for each n-gon.
Instead of explaining how to calculate the per-turn decay for an n-gon spiral, it's easier to tell you to use the per-segment decay option and enter the expression "1-cos(a)", without quote marks and where a is the segment angle.

regarding the goal: To finally achieve any initial object type or to achieve a "Curve(s)" object?
Surely the most flexible and straightforward solution would be to simply recover the base object of the Shape Text. That could then be converted to curves if the user specifically wants a Curve/Curves object instead of a parametric shape.

since turning a shape to a text frame needs to convert it to curves.
No, the parametric shape remains as the basis of the Shape Text, and its controls are available with Node Tool as usual, so the developers could easily provide a means of getting the parametric shape object from a Shape Text without a conversion to Curves.

Can the tool can produce polygonal spirals based on a simple recursive / flip pattern....? Below is an example of these spirals using 3-9 sided polygons, recursively scaled and flipped, creating the spiral as the blue line advances across each consecutive polygon while rotating around the center...
It can, but you'll need to calculate the decay percentage for a given polygon: cusped decaying spirals.afdesign

[...] It should be vector so that I can use it in a variety of ways [...]
Note that the black lines in your document are stroked with Affinity so-called vector brushes which really stretch or repeat a raster image along a path, and so you won't get a purely vector export from it.

Thank you so much!
You're welcome!
Today I attached a new 'procedural gradient.afphoto' file to my earlier comment. Its Procedural Texture uses some vector functions that are provided by Affinity, which might help you with learning about the functions.

The problem with this method is that I can't control the opacity of the curve and the text independently.
Publisher has a Text Frame panel for controlling properties of the object that is providing the path for text or a frame for text.

Only the first two brushes in the basic Pen Category will expand the stroke.
I'm not sure why you are bothering to state that. The video shows the expansion is happening, but the result is too skinny because of the bug I wrote about earlier in this thread.

I was trying to create a Radial Gradient in 32bit to use in Substance Painter. The Gradient Tool unfortunately gets only exported as a dithered gradient..
A trick that suppresses dithering of a vector gradient when exporting to a raster format: give the gradient-filled object an FX Colour Overlay with zero opacity: gradient tool gradient.afphoto
An alternative way to avoid dithering is to use an FX Gradient Overlay on an object: gradient overlay gradient.afphoto

Is my memory playing tricks on me?
You may be thinking of a Compound (non-destructive Boolean geometry) rather than a Group or Layer, because colouring a Compound does not affect its contained objects.

The transformation matrix of an object is influencing how the brush texture is mapped onto the path(s) of an object.
If you select your two curves and do Merge Curves then they will be stroked in a matching way, and then you can do Separate Curves if you require them to be separate objects.
