## Instructions
Read the sync capabilities in `src/index.ts` (and any imported modules). For each sync found, run through the checklist below. Report findings grouped by severity.
Before starting, read `.agents/skills/sync-guide/SKILL.md` for the full sync concepts reference.
### Critical Issues (will break the sync or cause data loss)
1. **No pagination termination**: Does `hasMore` eventually become `false`? Look for: infinite loops where `nextState` doesn't advance, missing base cases, conditions that can never be met.
2. **Cursor doesn't advance**: Does `nextState` change between iterations? If the cursor is the same as the previous state, the sync will loop forever. Check that each execute call makes progress.
3. **Missing first-run handling**: When `state` is `undefined` (first run), does the code handle it gracefully? Look for: `state.cursor` without `state?.cursor`, property access on potentially undefined state.
