CI's file-size check (which diffs against origin/main, not per-commit like the local lefthook gate) flagged useDomEditCommits.ts at 602 lines. Extracted the standalone atomic-patch-batch helpers (formatUnsafeFieldList, getErrorDetail, readErrorResponseBody, formatPatchRejectionMessage, patchElementBatches, batchesAreInlineStyleOnly, AtomicElementPatchConvergenceError) into useDomEditCommitsHelpers.ts — none of them close over hook state, so this is a pure move. useDomEditCommits.ts is now 451 lines. Typecheck/oxlint/oxfmt clean; useDomEditCommits.test.tsx (28 tests) and the full studio suite unaffected.
