Three store-level pinning tests for PLAN-2392's DR-15 — no behavior changes, locking down assumptions the copy / move / bundle paths rely on silently: - Clone independence: a cross-workspace copy mints a fresh, live attachment row that shares only the bytes (content hash), and soft-deleting the clone or the source never cascades to the other (both directions pinned; there is no store-level attachment restore, so delete stands in for the row-separation invariant a restore would ride). - A move charges both workspaces: ArchiveSource soft-deletes only the source ITEM; the source attachment rows (the original attached via item_id) stay live and their bytes are counted in both workspaces' storage usage. The clones land live on the copied item with the variant reparented to the new original. - Bundle round-trip orphan: WorkspaceAttachmentsForExport includes a live attachment whose parent item is soft-deleted, while ExportWorkspace's item list excludes that item — the divergence that leaves import unable to remap ItemID (handlers_import_bundle.go:479-510), landing the row as an orphan. Pinned as known behavior, not fixed. Dual-dialect (store helpers only; passes under make test-pg). Each pin was mutation-verified to fail when its behavior regresses (content-hash delete cascade, archive→attachment cascade by item_id, and an export that stops excluding soft-deleted items), and reviewed to a fresh-angle CLEAN.
