Coverage Summary for Class: SyncMeta (com.georgeci.moneysurfer.sync.repository)

 package com.georgeci.moneysurfer.sync.repository
 
 import kotlinx.coroutines.flow.Flow
 import kotlin.time.Instant
 
 /**
  * Per-(scopeKey, collection) sync metadata.
  *
  * - [cursor] — `lastPulledAt` value used as `WHERE updatedAt > cursor` filter
  *   in the next pull. Updated only when remote rows are successfully written
  *   to local Room within the same transaction.
  * - [lastSyncSuccessAt] / [lastSyncAttemptAt] — timestamps for the UI badge.
  *
  * [scopeKey] is typically a workspace id string. [collection] is an opaque
  * Firestore collection name string (e.g. "accounts", "transactions").
  *
  * Lives in `sync:api` rather than next to its Room-backed implementation because
  * the Settings → Sync screen reads the cursors: "a cursor newer than the remote
  * change" is the answer to "why did the pull bring nothing", and a feature module
  * must not depend on `sync:default` to ask it.
  *
  * See SyncCoordinatorFAQ.md №14, sync.md §4.3.
