  "notes": "Task 7 re-loop: initial mut_counter.ail draft used (app + lo (tail-app sum_helper ...)) which the tail-call analysis rejected as 'not in tail position'; restructured to accumulator-style passing acc as a third arg. Two beyond-plan adjustments absorbed inline (not counted as re-loops since they were structural extensions, not failed retries): (1) synth_with_extras Term::Var mut-var precedence in lib.rs, (2) lambda.rs save/restore + in-thunk splice. tests 592 -> 594 (+2 e2e)."
