...while this is not the main objective of this test case,
and another test will focus on invocation with full-fledged
`TestFrame` buffers and hash computation...
...it is still a nice achievement to see that these simple
algebraic operations used for demonstration can actually be
invoked in the whole connected network :-)
Using a Node network with
* two source nodes
* one of them chained up linearly with a filter node
* then on top a mix node to combine both chains
Can now verify the generated port specs and verify proper connections
at node level and at port level
This was a lot of intricate technical work,
and is now verified in-depth, covering all possible cases.
__We can now__
* build Nodes
* verify in detail correct connectivity
* read Node-IDs and processing specifications
* maintain a symbolic spec for the arguments of a Port
(and beyond that, we can also **invoke nodes**, which remains to be formally verified)
* this changeset builds a complex processing network for the first time
* furthermore, some ideas towards verification are spelled out
''verification not implemented''
...which aims at building up increasingly more complex Node Graphs,
to validate that all clauses are defined and connected properly.
Reconsidering the testing plan: initially especially this test was aimed
primarily at driving me through the construction of the Node builder and
connection scheme. Surprisingly enough, already the first test case basically
forced the complete construction, by setting me on tangential routes,
notably the **parameter handling**.
Now I'm returning to this test plan with an already finished construction,
and thus it can be straightened just to give enough coverage to validate
the correctness of this construction...
The namespace `steam::engine::test::ont` will hold some typical definitions
for the fake „media processing library“ — to be used for validating aspects of mapping and binding.
After the complete makeover of the `FeedManifold` structure,
which among other entails a switch from ''buffer arrays'' to tuples
and the ''introduction of a parameter tuple'', this changeset now
switches the „downstream code“ of the builder and node invocation,
relying on an largely identical invocation API.
The partially finished NodeLink_test now **runs as before**
but on top of a drastically more flexible and open infrastructure.
Quite a feat.
This is an attempt to take aim at the next step,
which is to fill in the missing part for an actual node invocation...
''...still fighting to get ahead, due to complexity of involced concerns...''
