STATEREPOSITORY_E_CONCURRENCY_LOCKING_FAILURE

STATEREPOSITORY_E_CONCURRENCY_LOCKING_FAILURE belongs to Windows StateRepository. It marks an optimistic update lost because the stored row changed after it was read. The useful starting point is the exact API, object and state transition that returned 0x80670001, because a shell or application message can hide that boundary.

First rejecting layer

Optimistic concurrency compares the caller’s read version with current repository state. The failure protects a newer write from being overwritten and should lead to reread-and-reconcile logic, not a database lock reset.

Smallest faithful test

First: Reread the entity in a new transaction.
Next: Reapply only changes that remain valid.
Then: Detect and surface true field conflicts.
Finally: Retry with a bounded conflict policy.

Diagnostic matrix

Entity key and original version token. This places the event on the lifecycle or transaction timeline within the Windows StateRepository boundary.
Current stored version. This separates caller input from environment and service state within the Windows StateRepository boundary.
Competing writer and transaction. This creates a stable comparison across retries or another machine within the Windows StateRepository boundary.
Fields changed by each writer. This pins the event to an object or resource generation within the Windows StateRepository boundary.

What each result would imply

Isolated connection against a repository copy: a changed result separates retained object, connection, path, host, or device state from the original input. Hold constant: preserve schema, data generation, and transaction sequence.
Reduced failing operation: If this result follows the reduced step, the rejecting transition is localized. Hold constant: retain entity key and original version token and remove only unrelated work.
Targeted corrective control: Use this as a diagnostic branch rather than a blanket workaround: reread the entity in a new transaction. Hold constant: keep the original sample available for the final regression test.

Limits of the HRESULT

BUSY and LOCKED codes concern inability to acquire database resources; optimistic failure occurs after a logical version comparison.

Do not overwrite the newer row or delete repository files to make the retry succeed.

Prove the repair

Treat it as corrected only when concurrent writers preserve both intended changes or report a deterministic conflict without lost updates; retain the original negative case so fallback cannot be mistaken for repair.
