…riodic sync - snapshot Arrow files across existing processing directories at startup - group files by event minute and output partition prefix - process conversion groups sequentially from oldest to newest - start periodic sync after snapshotting instead of waiting for recovery - leave recovered root Arrow files for periodic sync - prevent periodic sync from reusing startup-owned processing directories - remove all empty processing directories contributing to a completed group - retain the per-Parquet Arrow file limit to bound memory usage

WalkthroughStartup synchronization captures processing-file snapshots before periodic synchronization starts. Staging groups use deterministic ordering, sequential conversion, continued processing after errors, and cleanup across contributing directories. ChangesSynchronization ordering
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to Startup Arrow-file processing now snapshots and sequentially converts staged groups before periodic synchronization begins. No concrete merge-blocking risk remains identified. Sequence Diagram(s)sequenceDiagram

- Around line 1050-1061: Update the staging-files loop around
convert_arrow_group so an error in one group is recorded rather than propagated
immediately, allowing all later groups to be processed. After the loop
completes, report or return the accumulated failure while preserving successful
schema collection and existing Arrow-specific handling.

In `@src/parseable/streams.rs`:
- Around line 1056-1062: Update the startup group conversion flow around the
non-Arrow error branch and StartupSyncPlan::execute to retain or return failed
groups after continuing with later groups, so the startup coordinator can retry
or surface them instead of silently succeeding. Preserve processing of
subsequent groups, and update conversion_continues_after_group_error to verify
the failed group is retried or reported.
