Ibraheem Ahmed 1d6ae8596a [ty] Prefer exact matches when solving constrained type variables (#21165) ... ## Summary The solver is currently order-dependent, and will choose a supertype over the exact type if it appears earlier in the list of constraints. We could be smarter and try to choose the most precise subtype, but I imagine this is something the new constraint solver will fix anyways, and this fixes the issue showing up on https://github.com/astral-sh/ruff/pull/21070.		2025-10-31 10:58:09 -04:00
