I remember the direct quote where I think someone over heard a conversation between Alonso and Stroll. Alonso asked Lawrence if Newey was going to work on the 2025 car. Lawrence's response to Alonso was "Adrian's contract states that we can't tell him what to work on, he decides." Basically we need to ask Adrian. Think that article is trying to tell us what he will do on past experience of a car in AMR25 situation. The reality is it's just an attempt at a educated guess.
Imola is a long time to wait for an upgrade when you consider that testing ended on the 28th of February, Imola will be 14 weeks from the end of testing. What has the factory done since ? An F1 factory is setup to work on 2 cars at the same time(2 projects). I think the 2026 project is probably very advanced in that Bell had been working on it for over a year, all be it with small amount of staff. Newey knew the regs going in and since the AMR26 is basically a blank canvas, he could have come in with a plan for 2026.
My point is, they are either:
1 - Waiting for Newey
1a - When Newey arrived, he told them to give up on the year.
1b - Newey gave them direction
or
2 - They've given up on the year.
