Startup trusts offsets without reading record boundaries. Rebuild the index only from validated records.
Estimated field mix
Put returns success before the log flush completes. Define durable acknowledgement using the filesystem adapter.
Estimated field mix
A crash leaves a partial final record and startup refuses every key. Recover the valid prefix conservatively.
Estimated field mix
Rebuilding the index resurrects deleted keys because deletion only changed memory. Append durable tombstones.
Estimated field mix
A multi-key update survives restart with only half its changes. Add one bounded batch commit marker protocol.
Estimated field mix
Repeated updates grow the log. Write a compacted generation from one consistent logical view.
Estimated field mix
Crashing during compacted-file replacement leaves no selected log. Add a recoverable generation manifest.
Estimated field mix
Support has no way to identify damaged record offsets safely. Add a read-only inspection command.
Estimated field mix
Backup folders contain unnamed files with no declared schema. Add a bounded manifest describing required objects.
Estimated field mix
A backup includes partial uploads and later calls them missing documents. Inventory only committed archive references.
Estimated field mix
Copy completion alone marks backup success. Stream verification of every required object before success.
Estimated field mix
A document changes while backup runs and the manifest references an uncopied blob. Define one consistent capture boundary.
