Written and reviewed by Seller Profit Guard Editorial Team.

Record source pointer, export type, period, canonical grain, fingerprint recipe and version, threshold version, expected and observed groups, split exceptions, candidate dispositions, retained references, reviewer, reason, downstream reconciliation, privacy classification, backup, stop rule, restoration test, and dated changes.

Duplicate Review Audit Template: grain and provenance integrity control

Partition every packet by source type, canonical event grain, currency, period, and version before grouping. Control 1 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

Mixed populations block. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: fingerprint and candidate evidence control

Version the fingerprint recipe and distinguish exact tokens, probable business keys, repeated identifiers, and legitimate exceptions. Control 2 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

A candidate is not identity proof. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: threshold and expectation control control

Declare timestamp, amount, expected-group, and unexpected-group rules before running fixtures. Control 3 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

Changes require retesting. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: dated confirmation contract control

Require real source-review and policy-effective dates, keep policy no later than source review, affirm all nine controls, and reject copied duplicate-import and split-shipment packets. Control 4 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

Missing or duplicated evidence blocks. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: bounded public packet control

Limit each scenario to 2–100 synthetic rows and 50,000 evidence characters, strictly parse thresholds, and mask every derived group under Block. Control 5 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

A public worksheet is not a production deduplication engine. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: privacy and output minimization control

Use invented public descriptors, report counts only, and keep protected rows in authorized storage. Control 6 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

Never echo private values. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: human disposition authority control

Require a named reviewer, retained reference, reason, reconciliation, and approval before excluding anything. Control 7 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

Ready cannot delete. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Duplicate Review Audit Template: monitoring and restoration control

Preserve source, prior rules, dispositions, derived totals, stop triggers, and a tested restore path. Control 8 defines a pass condition, evidence owner, independent reviewer, correction deadline, counterexample, monitoring signal, stop condition, and restoration trigger for reviewable change history.

Rollback evidence is mandatory. Apply it while keeping structural validation, canonical mapping, candidate grouping, protected disposition, downstream reconciliation, and destructive authority separate.

Evidence boundary for reviewable change history

The duplicate-import packet contains two invented order rows sharing one fingerprint plus one unrelated row. The split-shipment packet repeats an ORD-SYN key across distinct shipment roles, values, timestamps, and fingerprints.

The packet demonstrates entered candidate-group logic only. It cannot prove production identity, deletion safety, source completeness, platform error, fraud, accounting accuracy, privacy compliance, payout reconciliation, tax treatment, or the correct retained record.

Release, monitor, and restore the duplicate-review audit packet

Block shape, pattern, timestamp, numeric, source, fingerprint, role, context, threshold, privacy, evidence, scope, or conflict failures. Review probable or unexpected groups. Ready clears only fixtures that match declared expectations.

Before indexing or operational use, preserve evidence and rollback artifacts; run typecheck, unit, integration, build, content, similarity, SEO, image, link, privacy, mobile, strict-route, deployment, and live checks; then monitor drift without claiming causality.
