My reply in 4 parts:

1. You don't work "under a senior dev" or "architect". You should just remove that junior label now. And you are a senior as well. In fact, every developer should also be an architect.
2. Then you are 100% right, OpenAPI or something similar is the way to go. I hope you have more developers in your team you can talk to about this solution direction and WoW.
3. That whole composer story is definitely a clear situation you are the senior.

So that being said. I think something else is also going on, communication and relationship. I bet he is actually a bit afraid of you doing (too) good and being successful at your job. So then this "senior guy" might think it he doesn't come across well.

My advice here is to try to first repair the relationship with him, talk with him at the coffee about other stuff. Maybe you have hobbies in common?

Then next you really want to involve more people at this stage, ideally 4 or 5 team members should be on-board in order to brainstorm together.

Most importantly, try to not push your changes, this person seems a bit unable to cope with change (I hope he is not too old :P?). Another approach is "pull management"; try to make him curious about the topics, be positive and praise others where applicable, focus on the strengths of the developers, support each other.

@Crunkle_Foreskin yea I know this behavior very well. It's not pleasant. In fact, its very frustrating.

Maybe he is very busy, and doing all kind of stuff as the same time. Causing to lose focus and patience.

Some chit-chat might work.. You also can just ask him DIRECTLY: Do you want to share something with me? (maybe there are other things going on? Maybe even not work related).. Or: Why don't you think my concerns are invalid? And/or: Should I change my communication with you?..

@Crunkle_Foreskin I first thought US actually, since they also have a cultural hierarchy. I never worked in the UK, but maybe this same kind of hierarchy exists in UK workforce as well?

Anyway, I'm from The Netherlands. And often the Dutch are very direct. Ask direct questions. Speak-up. Etc. Of course it also depends on the person, people who are very shy remain silent.

I understand you are also afraid to lose your job if you are still in your probation period.
