+ * Unix-style dotfile hide convention.

+ * A file / folder is considered "hidden" when its display name starts
+ * with a `.`. This matches the convention used by every Unix shell,
+ * macOS Finder (with Cmd+Shift+.), and every cloud-share product that
+ * offers a hide toggle (Nextcloud, ownCloud, Seafile).
+ *
+ * Windows-style HIDDEN attribute is not honoured — the attribute isn't
+ * preserved across upload / dedup, and OxiCloud stores content-
+ * addressable blobs without any filesystem metadata carrier. Matches
+ * Nextcloud desktop client behaviour, which also strips HIDDEN on
+ * upload.
+ *
+ * Scope: this helper is UI cosmetics ONLY. A direct URL to a hidden
+ * file (`/files/<uuid>`) still resolves; batch operations only touch
+ * what the UI actually rendered; WebDAV / NC / CalDAV surfaces are
+ * unaffected because they consume the raw API responses. The whole
+ * filter lives at the render layer, keyed on
+ * `preferences.hideDotfiles`.

+-- Add opaque UI preferences bag to auth.users.
+--
+-- Purpose. Cross-device persistence of pure UI toggles (hide dotfiles,
+-- view mode, group-by choice, sidebar collapse, …). The server NEVER
+-- inspects the contents — this column exists solely so that the SPA can
+-- fetch its own settings from `GET /api/auth/me` on a fresh browser and
+-- write them back via `PATCH /api/auth/me/profile`.
+--
+-- Design rule. Preferences that ONLY affect the UI live here.
+-- Preferences the SERVER reads (locale for magic-link templates,
+-- notify_on_share for the notification pipeline, role for authz) stay as
+-- typed columns. When a UI-only preference graduates to server-relevant,
+-- promote it to a column and drop the JSON key in a follow-up migration.
+--
+-- Merge semantics. `PATCH /api/auth/me/profile` performs a SHALLOW
+-- merge via `ui_preferences || $1::jsonb` in `pg_user_repository.rs`,
+-- optionally stripping nulls (frontend convention: sending `{key: null}`
+-- clears the key). Full replacement isn't offered — every operation is
+-- additive so a partial write from Device A doesn't wipe prefs set on
+-- Device B.
+--
+-- Size cap. Enforced via CHECK constraint: 16 KiB compressed JSONB is
+-- generous for realistic UI prefs and prevents the endpoint from being
+-- used as a scratch key-value store. `pg_column_size(ui_preferences)`
+-- returns the on-disk byte size which is what actually consumes rows.
+ALTER TABLE auth.users
+    ADD COLUMN ui_preferences JSONB NOT NULL DEFAULT '{}'::jsonb;

+-- Object shape only — arrays / scalars / null are rejected. The merge
+-- semantics assume an object; a scalar in this column would break the
+-- shallow-merge SQL. Cheap check (single jsonb_typeof call).
+ALTER TABLE auth.users
+    ADD CONSTRAINT users_ui_preferences_is_object
+        CHECK (jsonb_typeof(ui_preferences) = 'object');

+# =============================================================
+# OxiCloud — auth.users.ui_preferences round-trip
+# =============================================================
+# The `ui_preferences` JSONB column is the SPA's cross-device
+# backing store for pure UI toggles (hide dotfiles, view mode,
+# sidebar collapse, …). The server treats the contents as
+# opaque; this suite pins the semantics of the PATCH surface
+# so a future refactor can't silently break cross-device sync:
+#
+#   1. Fresh user starts with an empty object bag (`{}`), not
+#      `null` and not missing from the response body.
+#   2. PATCH does a SHALLOW merge — a partial write only
+#      touches the keys it mentions; siblings survive. Load-
+#      bearing invariant: without it, Device A's write would
+#      silently wipe preferences Device B just set.
+#   3. Sending `{key: null}` in the patch REMOVES that key
+#      server-side (jsonb_strip_nulls after the merge). This
+#      is the documented delete-a-key path.
+#   4. Non-object patch shape is rejected with 400. Prevents
+#      the endpoint from being a scratch scalar store and
+#      catches malformed clients early.
+#
+# Not covered here (intentional):
+#   • 16 KiB size cap — the CHECK is at the schema layer and
+#     is exercised by unit tests without needing an integration
+#     round-trip; constructing a 16 KiB JSON body in Hurl adds
+#     line noise without meaningful signal.
+#   • Concurrency safety of the shallow merge under two
+#     simultaneous PATCHes — postgres' `||` operator is atomic
+#     per row, so this is a DB-guarantee test rather than an
+#     API test.
