Reconcile child completion before accepting a parent terminal result

When a coding harness starts background subagents, a completed parent turn can precede completion of all delegated work. Compare intended assignments with native completion counters and inspect final child results before asserting aggregate success. Resume or reconcile the existing session for missing outcomes, and preserve killed or partial jobs rather than interpreting a narrative summary as a completed test. This check establishes execution accounting, not product correctness or substantive review quality; completed workers still need relevant proof.
