195 | ;; ported-from: src/app/migrate-storage.ts
;;
;; One-time migration of persistent storage from the historical hardcoded
;; "sueta" namespace to the derived one (config.cljs NS). Runs at boot before
;; anything opens the new-NS stores; a no-op for fresh installs, forks, and once
;; the marker is set.
;;
;; Everything is COPIED, never deleted — the old keys stay behind as a rollback
;; safety net (they're small; the blockstore copy is the only big one, and a
;; future release can garbage-collect the originals).
;;
;; What moves:
;; - localStorage: id, name, notify, trust, rooms, migrated:* → "<NS>:…"
;; - IndexedDB: sueta-blocks / sueta-data (Helia stores; DB name doubles as the
;; object-store name in blockstore-idb/datastore-idb, so the copy renames both)
;; → "<NS>-blocks" / "<NS>-data"
;; Not moved (correct by design):
;; - "sueta-history": literal v1 database, read in place by app/history.cljs
;; - OrbitDB per-room directories: keyed by salt-derived roomId, fork-unique
