scripts/review-package generates the reviewer's input deterministically:
commit list, stat summary, and net diff with -U10 context, written to a
file from an explicit BASE. Live runs showed controllers improvising
'git diff HEAD~1..HEAD', which silently truncates multi-commit tasks,
and svelte's five fix dispatches shipped without re-running any tests —
fix dispatches now explicitly carry the implementer's
re-run-and-report contract.
