Invalid PSBTs need to be re-created, so the next role is the
Creator (new PSBTRole). Additionally, we need to know what went
wrong so an error field was added to PSBTAnalysis.
A PSBTAnalysis indicating invalid will have empty everything,
next will be set to PSBTRole::CREATOR, and an error message.

src/node/
The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
The src/node/ directory is a new directory introduced in
#14978 and at the moment is
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
