What
Directory sync sends your local file changes to a remote session in rounds. Each round now records two more values, heldOpen and heldOnly. A round that was sent can also be marked basisLink, which is logged as basis_link in usage reports.
Why
This is internal record-keeping with no visible change on its own.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what `heldOpen`, `heldOnly` or `basisLink` mean.
