A tablet retries saved edits with new request IDs, so the server creates duplicate inspection findings.
Estimated field mix
A contractor loses project access while offline, then reconnects with a batch of previously authorized edits.
Estimated field mix
The sync service treats every concurrent change as either a blanket overwrite or a blanket conflict.
Estimated field mix
The server applies a change, loses the response, then reapplies it after the tablet reconnects.
Estimated field mix
Two inspectors change a safety finding from different base revisions and last-write-wins hides one observation.
Estimated field mix
A reviewer resolves a conflict while a third offline proposal arrives, silently discarding the new observation.
Estimated field mix
A tablet that missed a deletion resubmits its old finding and recreates content the team intentionally removed.
Estimated field mix
An inspection references a photo before its interrupted upload completes, producing broken evidence links in the field report.
Estimated field mix
The tablet stores a local cursor before receiving server confirmation and skips updates after a crash.
Estimated field mix
A tablet says all synced even though uploaded changes contain unresolved conflicts and a pending attachment.
Estimated field mix
A configuration change adds a checker while a run is in progress, so the completion predicate changes halfway through.
Estimated field mix
A timed-out policy checker returns an empty findings list, which the aggregator interprets as passed.
