An install over an app's kept drive folder (appdata/<app> non-empty) asks the household: "use my kept data" (a load from the newest copy of THIS drive's install, own unit or second-drive mirror, then the template's after_load) or "start fresh" (the folder is renamed into <drive>/kept/<app>/<date>/ with the removed app's unit; nothing deleted). The install API answers 409 kept_data_choice until one is chosen; DeployStack refuses too. New page Megorzott adatok / Kept data (/kept-data): Load / Look / Delete (typed confirmation, the only deletion of kept data). FileBrowser gets a read-only source. The drive-full warning names the kept folders. <drive>/kept is protected and outside every backup leg. R-690: the removed-app restore (R-487) never found a unit on a DATA drive — it asked GetStackComposePath (true for every catalog app) and restored nextcloud with no env. Now isStackDeployed; pinned with a production-shaped provider. Red-proofs: audits/night-2026-09-26/E/redproofs/.
