/**
 * Gate judgment (plan B2a/B2b, items 8 and 10, with the B-core amendments and
 * next-wave B1/B2/B5): findings carry `changes`; a user challenge both voices
 * raised on a confirmed finding with the same `changes` recommends `b` only
 * with one shared proposal (the parent's override, or the same remedy from
 * both), rendering both remedies verbatim and the basis; anything weaker keeps
 * `a` with its basis. APPLY keys on the chosen option's `changes_plan`;
 * accepted changes are pending amendments (status amend_pending, nothing
 * reopens at answer) that `next` refuses past (PLAN_AMEND_PENDING) until
 * `revise --incorporates` binds them to a changed plan or `--withdraw` drops
 * them. `as-is` keeps every direction; `rec` (alias `all`) takes every
 * recommendation. Partial replies resolve against persisted decisions. On
 * reruns a challenge without `changes` is an agent decision that reopens
 * nothing, and rerun prompts carry the decided items.
