# Mutation Outcome Tracking
|
|||
|
|
|
|||
|
|
Context: a remote write can finish even when its response disappears. Problem:
|
|||
|
|
transport failure leaves acceptance uncertain. Recoverability competes with latency,
|
|||
|
|
retention cost and backend complexity.
|
|||
|
|
|
|||
|
|
Proposed solution: track each attempt as pending, accepted, explicitly rejected or
|
|||
|
|
unknown. Bind retry identity to the original payload and authority scope. Resolve
|
|||
|
|
unknown outcomes through a documented operation lookup or idempotent replay within
|
|||
|
|
its retention contract. Changed intent gets a new identity. Without such a contract,
|
|||
|
|
require reconciliation rather than claiming an automatic retry is safe.
|
|||
|
|
|
|||
|
|
Consequences: feedback can be honest about uncertainty; operation history consumes
|
|||
|
|
resources. Expired receipts and lost identity need an unresolved recovery path.
|
|||
|
|
Timeout, cancellation or a generic server error alone cannot prove rejection.
|
|||
|
|
Disabling a button limits interaction, not server execution or duplication.
|
|||
|
|
|
|||
|
|
Evidence: T03 documents Stripe's bounded idempotency mechanism; T04 demonstrates why
|
|||
|
|
browser cancellation is insufficient. Neither establishes this full frontend state
|
|||
|
|
model or a second independent known use. Recurrence: unknown. Hypothesis only.
|
|||
|
|
|
|||
|
|
Proposed connection: acceptance enables [Invalidate and Reproject](InvalidateAndReproject.md).
|
|||
|
|
Compare [Pending Synchronization](PendingSynchronization.md): local commit can already
|
|||
|
|
be valid there while remote propagation remains unacknowledged.

T01–T05 refer to [TransactionalEvidenceExpansion](../reviews/TransactionalEvidenceExpansion.md).

|
Connections are research proposals, not admitted graph edges.

Reasoning exercise: [VC-01](../walkthroughs/VC01-TransactionalAdministration.md).
