"""Incremental-sync coordination layer (Task 2.7).

This package ties the scrapers (``app.scraper.*``) and the persistence layer
(``app.storage.repos``) together with **resumable, incremental** sync via the
``SyncState`` watermark table and the ``SyncRun`` audit log.

Public surface:

* :mod:`app.sync.watermarks` — SyncState CRUD (per-entity / per-channel /
  per-scope cursor get/set + convenience accessors).
* :mod:`app.sync.orchestrator` — the sync brain. One entrypoint per entity
  (``sync_wechat_messages`` / ``sync_wechat_friends`` / ...) plus a coordinator
  (:func:`app.sync.orchestrator.sync_all_wechat`). Each run is logged as a
  ``SyncRun`` row (started → success/failed) so the dashboard / ops view can
  report progress and errors.
