Proposed edit

Before retry: read by request identity; preserve an existing record and its owner.

Original failure

After-commit timeout → exactly one record in candidate.

Prior success

Normal write → exactly one record and correct confirmation.

Why was one approved request saved twice?

Reconcile by stable request identity before retrying a write. Preserve approval and confirm only the saved result.

Reconcile a stable request identity before retrying. Then challenge the edit with denied access and missing observations, rather than testing only the happy path.

Proposed edit

Before retry: read by request identity; preserve an existing record and its owner.

Original failure

After-commit timeout → exactly one record in candidate.

Prior success

Normal write → exactly one record and correct confirmation.

Counterexample

Access denied → no write or substitute destination.

Missing evidence

Unreadable destination → no completion claim.

Review package

Exact tested revision, environment reset proof, per-case results and unresolved limits.

The candidate is a proposal. Passing these authored conditions does not establish broader regression qualification or authorize release.

Keep the original failure, cause hypothesis, expected behavior and proposed edit connected. Use a versioned proposal when the fix is a policy or configuration change. Use a customer PR only where repository access and edit scope support it.

— Exact failure and source references

— A bounded edit surface and named owner

— No invented PR for an unsupported write path

Test the candidate against the original failures, previous successes and known misses. Keep the expected results independent of the candidate. Inspect regressions, policy violations and incomplete arms before qualifying the change.

— Matched input and verified equivalent state

— Baseline and candidate versions pinned

— The tested revision is the revision offered for review

Release and follow through

A reviewed change still has an outcome to prove.

A reviewed change still has an outcome to prove.

A reviewed change still has an outcome to prove.

The owner reviews and releases the change. Tensile’s proposed lifecycle retains the decision and checks subsequent customer work. A merged PR does not establish a successful deployment or an improved customer result.

— Release decision and deployment evidence stay separate

— Later recovery does not erase an earlier harmful action

— Reusable regression cases carry the lesson forward
