The expired-job retention loop re-scanned the same oldest rows on every batch. When the oldest completed jobs are undeletable (children of a still-active root flow), the ORDER BY completed_at ASC scan walked that protected prefix on each of the up-to-20 batches, doing a v2_job PK lookup per row — quadratic in prefix size (measured ~9s/batch, ~180s/cleanup-cycle on a 1.5M-row prefix). Carry a completed_at watermark (max deleted) across batches and re-apply it as completed_at >= floor so each batch resumes past the already-processed prefix. Also skip the v2_job join entirely when no old root flow is active (the common case), since nothing is protected then. Measured: subsequent batches 9000ms -> 159ms; empty-set path 154 -> 36ms. The watermark only ever skips rows the current run already deleted, was protecting, or skip-locked — all deferred to the next run, identical to the unbounded scan's row set (verified: union of batched deletes == single delete, 0 diff).
