kept data: the choice at reinstall, the list, the read-only view, the load (09 decision 36); R-690 fixed

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.

+### Kept data — the choice at reinstall, the list, the read-only view (`09` §3 decision 36)
+
+An app removed with „keep my data" leaves its private drive folder (`<drive>/appdata/<app>`). Since this release
+that folder is never a dead end, and an install never runs into it silently (R-657).
+
+- **At install.** When the app's `${HDD_PATH}/appdata/…` bind already holds something, `POST /api/stacks/<n>/deploy`
+  answers **409** with `data.code = "kept_data_choice"` and the sentences (title, body, the two choices, „Erről nem
+  készül mentés." / "This is not backed up.") in the request's language; nothing is written. The page asks, and
+  sends again with `kept_data`:
+  - `use` — **„A megőrzött adataimat használom" / "Use my kept data"**: a LOAD from the newest copy that holds the
+    app's data and was taken of THIS drive (the app's own unit, Tier 1, or a second-drive mirror, Tier 2 —
+    `backup.KeptDBCopy`), through the one unit-restore body (`RestoreFromRecoveryUnitAt`); then the template's
+    `after_load:` once. Refused 409 with the `use_off` sentence when no such copy exists.
+  - `fresh` — **„Tiszta lappal kezdem" / "Start fresh"**: the old folder is MOVED (a rename on the same drive;
+    EXDEV or any failure puts back what moved and refuses) to `<drive>/kept/<app>/<YYYY-MM-DD_hhmmss>/` with a
+    `.felhom-kept.json` marker; the removed app's own unit moves in with it (`kept/.../unit`) so the files keep
+    their database copy; then the normal install.
+  - no choice → `DeployStack` refuses too (`ErrKeptDataChoice`), before any write.
+- **„Megőrzött adatok" / "Kept data"** — `GET /kept-data` (linked from Tárhely → Meghajtók): every dated kept
+  folder and every non-empty `appdata/<x>` no installed app binds, on every connected local drive — app, date,
+  size, which copy can bring it back (or none). **Load** (`POST /kept-data/load`, only with a copy; puts a dated
+  item's files back first, refuses over an occupied folder), **Look** (the file browser), **Delete**
+  (`POST /kept-data/delete`, the app's name typed to confirm — the ONLY deletion of kept data; the box never
+  deletes one by itself, D3 is open).
+- **Read-only view.** FileBrowser gets a source „Megőrzött adatok" / "Kept data" (box language) at
+  `/srv/megorzott/`, one `:ro` bind per listed item, present only when something is kept; the list page re-syncs
+  it (no recreate when nothing changed). Known limit: an app folder owned by another user with mode 0770
+  (nextcloud's `www-data`) shows as a folder FileBrowser cannot open.
+- **Where it lives.** `<drive>/kept/` is beside `appdata/` and `userdata/`, inside neither: no app bind, FileBrowser
+  userdata source, Samba share or backup leg reads it. It is in `ProtectedHDDPaths`.
+- **The drive-full warning** ends with the kept folders on that drive and their sizes (`fillwatch.SetExtra`).
+- **R-690 (fixed here).** The removed-app restore (R-487) never found a unit on a DATA drive — it asked
+  `GetStackComposePath`, true for every catalog app — and restored with no env. It now asks `isStackDeployed`.
+- `.felhom.yml` **`after_load: {service, user, command: [...]}`** — one command run with `docker compose exec -T`
+  after a load; nextcloud declares `php occ files:scan --all`.

+// ── Kept data (`09` §3 decision 36, operator ruling 2026-09-25 evening) ────────────────────────────
+//
+// WHAT IT REPLACES. „Remove the app, keep my data" left the app's private drive folder
+// (`<drive>/appdata/<app>`) behind, and a later install of the same app ran straight into it (R-657):
+// measured 2026-09-23 as an install loop, and 2026-09-25 as a clean install whose database simply knows
+// nothing of the old files. Nothing listed the folder, nothing opened it, nothing deleted it.
+//
+// THE RULING. A reinstall over kept data asks: "use my kept data" (the database from a backup, with the
+// kept files) or "start fresh" (the kept files MOVE to a dated folder; nothing is deleted). And kept data
+// is never a dead end: the household can see it (read only), load it later, and delete it.
+//
+// FOUR RULES, each a guard with a test:
+//
+//  1. ONLY `<drive>/appdata/<…>` IS "OLD DATA". An app's bind under userdata/ or media/ is the household's
+//     own shared files (a music library, a photo folder) — never moved, never listed here. Pinned by
+//     TestKept_OnlyAppdataBindsAreOldData.
+//  2. "START FRESH" IS A RENAME ON THE SAME DRIVE — never a copy, never across drives. A rename that
+//     fails with EXDEV (or anything else) puts back what it already moved and refuses. Pinned by
+//     TestKept_KeepAsideIsARenameAndRollsBack.
+//  3. THE KEPT FOLDER IS `<drive>/kept/<app>/<date>/` — beside appdata/ and userdata/, inside neither:
+//     no app bind reaches it, FileBrowser and Samba serve only userdata/, and no backup leg reads it (the
+//     Tier-2 and off-site legs read userdata/ and the declared binds of DEPLOYED apps). It is in
+//     ProtectedHDDPaths. The page says it is not backed up.
+//  4. THE BOX NEVER DELETES KEPT DATA BY ITSELF (D3 is open). DeleteKept is reachable only from the
+//     household's typed confirmation, and refuses any path that is not a listed kept item. Pinned by
+//     TestKept_DeleteRefusesAnythingNotListed.
+
