Function known_project_refusal 

pub(crate) fn known_project_refusal(known: &str, own: &str) -> String

The refusal for a spawn whose tree resolves to a project forge.toml declares (D3). One source: the facade refuses with it before it ensures anything, and the handler refuses with it as the shared core both dispatch sources pass through.

The sentence interpolates a project NAME, which is whatever a project is called - “worktree” included - and the classifier scans this text for exactly that word. What keeps it a dispatch failure is the classifier’s own guard on the phrase “which forge.toml declares”, which sits ahead of the name in both arms.
