What the storage layer actually holds versus what the database believes.

Read-only. missing_blobs is an INCIDENT, not a metric: each entry is a case that will 404 when a physician opens its image, or ship to a buyer as a reference resolving to nothing. orphan_blobs is disk cost only — reported, never deleted, because a wrongly-deleted blob is unrecoverable once the partner bundle behind it has aged out of its retention window.

Also returns the live durability verdict for all three stores, so the operator can see why blobs went missing rather than only that they did.
