SynchronizationProvider.rs

1//! # SynchronizationProvider (Environment)
2//!
3//! Implements [`SynchronizationProvider`] for [`MountainEnvironment`],
4//! providing two-way synchronisation of user data across devices.
5//!
6//! **Current status: stub.** Both methods log a warning and return
7//! successfully without contacting any backend. Production work will
8//! integrate with a cloud sync service (Firebase, Supabase, or custom).
9//!
10//! ## Operations
11//!
12//! - `PushUserData` - upload local settings/keybindings/extensions/snippets
13//!   snapshot to remote; detect conflicts via version vectors; queue when
14//!   offline.
15//! - `PullUserData` - download latest remote snapshot; apply changes or surface
16//!   conflict UI in Sky via notifications.
17//!
18//! ## Conflict resolution strategies (planned)
19//!
20//! Latest Wins · Local Wins · Remote Wins · Manual · Three-way Merge
