Line 310 `ring` — "No goals to be solved": the `field_simp [hx0]` at 309 already closed the goal! (field_simp can close field identities on its own.) Fix: remove the trailing `ring`. Or replace `field_simp [hx0]; ring` with just `field_simp [hx0]` — but if field_simp reduces to a non-closed form, need ring. The safe pattern: `field_simp [hx0]` then try ring only if needed — but "No goals" means field_simp closed it. Remove line 310's `ring`.
`field_simp` closed the goal itself — removing the trailing `ring`.
