- The dump inlined every linked sheet's rules as active CSS, so a print sheet's 12pt black text or an alternate theme produced tiny-text and palette findings the user never sees; disabled and alternate sheets are skipped and a media-scoped sheet is wrapped in its @media block. - The cross-run dump sweep is gone: two same-day reviews shared REPORT_DIR and one run's sweep deleted the other's dumps mid-audit. Dumps stay per run, owner-only, deleted after Phase 9 unless --keep-dom (now defined in the prose), and an interrupted run's dumps wait for the user. - Prose: design-system-* rows in DOM mode compare the page to THIS repo's DESIGN.md and apply only to the repo's own app; an empty scan JSON with exit 0 means the probe state changed since Setup (read stderr); the persist block names a missing dump instead of mislabeling it as a redaction block.
