State management in test scenario

[InvictusMB]

I haven't found any specific guidelines on managing state in test scenarios other than Delayed assertions section.

I want to create a Task to solve captcha for an integration test of the API. Captcha lives in JWT inside cookie which I can decrypt if I know a secret.
The task could be split into 3 smaller things:

• fetch captcha
• decrypt cookie
• send solved captcha

I need a way to pass data between those. My best guess is that I could use Ability to store the state and Question to pull it out for further interactions.

This is how I would approach the implementation:
I can imagine I will need CallAPIEnpoints ability in the first place. That ability should also be able to expose cookies of the latest request. I will then use that ability inside FetchCaptcha interaction.
I can use TakeNote interaction to save intermediate state but that needs a Question. So I will create a LastRequestCookie question.
Then I will need DecryptToken ability that will be used by DecryptCaptcha interaction. DecryptCaptcha interaction will also take Question as an argument.
That question will be something like NoteOnATopic. Which might be a good addition to Serenity core btw.
There will be LastDecryptedToken question to access the state of DecryptToken ability.
And finally a PostSolvedCaptcha interaction that takes a Question as an argument.

The pseudocode might look like this:

SolveCaptcha <--- Task
	FetchCaptcha <--- Interaction
		CallAPIEnpoints <--- Ability
	TakeNote.of(
		LastRequestCookie <--- Question
			CallAPIEnpoints <--- Ability
	).as('captchaToken')

	DecryptCaptcha.from(NoteOnATopic('captchaToken'))
		DecryptToken
	TakeNote.of(
		LastDecryptedToken <--- Question
			DecryptToken <--- Ability
	).as('captchaSolution')

	PostSolvedCaptcha(NoteOnATopic('captchaSolution'))
		CallAPIEnpoints

Does that make sense or I am making it too complex?
I believe I could get away without taking notes if those interactions would always come together in that sequence.

SolveCaptcha
	FetchCaptcha
		CallAPIEnpoints
	DecryptCaptcha.from(LastRequestCookie)
		DecryptToken
	PostSolvedCaptcha(LastDecryptedToken)
		CallAPIEnpoints

Are there other ways to pass data between interactions?
It looks a bit ugly to me because questions become tightly coupled with implementation details of an interaction but that coupling is implicit.
If FetchCaptcha implementation details change and it starts using different ability, LastRequestCookie question would know nothing about it and will just fail in run time.
