 - **"My** **`rk45`** **trajectory isn't evenly spaced."** - Expected behavior; `rk45` is adaptive. Pass `points` if you need a uniform grid.
 - **"My stiff system diverges with** **`rk4`****/****`euler`****/****`rk45`****."** - Switch to `implicit_euler` or `bdf2`.
 - **"My results look stable but seem slightly off compared to a reference."** - If you're using `implicit_euler`, try `bdf2` at the same step size - implicit Euler's stability doesn't guarantee tight accuracy.
-- **"I asked for** **`state`** **on** **`diffeqnPath`** **or** **`diffeqnPathHO`** **and got only `t,y[0]`."** - Check that the final `presentationStrategy` argument is exactly `state`. With `state`, path methods return `t` plus the complete internal state; with `trajectory`, they return only `t,y[0]`.
