B5 switched heal enumeration to list_object_versions, which only reflects the read-quorum metadata view: a version present on fewer than read-quorum disks was never enumerated, so it was never healed. Add a per-erasure-set disk-walk UNION enumerator (mirrors MinIO global-heal.go objQuorum=1 listPathRaw + mergeXLV2Versions) that surfaces every (object, version) present on ANY disk and feeds each to the existing per-version heal_object. - filemeta: MetaCacheEntries::resolve_union (dir_quorum=1/obj_quorum=1) yields the cross-disk version union at one tested seam. - ecstore: SetDisks::heal_walk_versions_page (list_path_raw fan-out, min_disks=1, dual object/version page bound, inclusive-forward de-overlap) + ECStore delegator + HealWalkVersion. - ecstore data-safety guard: before dangling-delete, try_regenerate_recoverable_meta physically probes part files via check_parts; when >= data_blocks data shards survive (meta lost but data recoverable) it regenerates xl.meta from a surviving FileInfo with the correct per-disk shard index instead of dangling-deleting. Genuine torn writes (< data_blocks) keep the current behavior — no resurrection. - heal: dw1: forward-marker cursor codec (reuses ResumeState.resume_cursor, idempotent restart on foreign tokens); list_versions_for_heal_page_disk_walk trait method (default falls back to the B5 read-quorum path); heal_bucket_with_resume selects the disk-walk enumerator when scan_mode==Deep || source==AutoHeal, else the unchanged B5 path; anti-loop guard aborts on (empty && truncated). Closes rustfs/backlog#920
