@zilto I am not 100% sure at the moment why the ty-checks have started to fail suddenly at the moment and it's a bit too late for me to figure it out if you get a chance to look at it check it out else I will get to it later in the day tomorrow after class

@zilto all yours for now, two important things that we need to tackle

• wait for devel to release this week and freeze the dlt version moved it to devel for now
• at the moment i add uv run ty check --exclude tests --output-format concise . because I tackling them is taking a lot of time and I would prefer tackling them later in another PR.
