Extracted 8 helper functions from the monolithic flushToJSONLWithState:
- recordFlushFailure/recordFlushSuccess: Failure tracking and counter management
- readExistingJSONL: Parse existing JSONL file for incremental merging
- fetchAndMergeIssues: Fetch dirty issues from DB and merge into map
- filterWisps: Remove ephemeral (wisp) issues from export
- filterByMultiRepoPrefix: Multi-repo prefix filtering for non-primary repos
- updateFlushExportMetadata: Store hashes and timestamps after export
- getIssuesToExport: Determine full vs incremental export issue list
Main function now reads as a clear pipeline:
1. Validate integrity -> 2. Get issues -> 3. Read existing JSONL
4. Merge from DB -> 5. Filter wisps -> 6. Filter by prefix
7. Write atomically -> 8. Update metadata
Benefits:
- Each helper is single-responsibility and testable
- Main function reduced from ~280 to ~94 lines
- Logic is clearly separated and documented
- Easier to understand and maintain
