NATAegisFlow Artifact Workflow Example¶
This worked example shows how to complete the NATAegisFlow Artifact Workflow Checklist Template for an ETL patch that changes customer risk segmentation logic.
Artifact and Story Details¶
| Field | Value |
|---|---|
| Artifact ID / Name | ETL-RISK-SEG-042 / Customer Risk Segment Mapping |
| Related Story / Requirement | US-RISK-218: Update premium customer risk segment calculation |
| Artifact Type | ETL mapping patch and semantic validation report |
| NATAegisFlow Run ID | NAF-2026-07-23-018 |
| Owner | Data Engineering Lead |
| Reviewer | QA Semantic Reviewer |
| Approver | Risk Data Product Owner |
| Target Release / Sprint | Sprint 24.7 |
Completed Acceptance Criteria¶
- Artifact scope, source inputs, target outputs, and affected consumers are identified
- Semantic validation checkpoints are defined for glossary terms, lineage, transformation intent, and rule outcomes
- NATAegisFlow findings are reviewed and assigned a disposition: resolved, accepted, deferred, or false positive
- Critical and high semantic findings are resolved or have documented risk acceptance
- Patch validation is complete for all changed mappings, rules, evidence files, and downstream references
- Required evidence is attached and accessible from the story or artifact record
Semantic Validation Checkpoints¶
| Checkpoint | Expected Evidence | Status | Notes |
|---|---|---|---|
| Business meaning preserved | NATAegisFlow semantic comparison, reviewer notes | Pass | Premium customer definition matches approved glossary update BG-117. |
| Lineage and source-to-target mapping verified | Lineage export, mapping spec, data contract reference | Pass | Source fields customer_value_score and tenure_months map to approved target fields. |
| Transformation rules match approved intent | Rule evaluation output, sample validation, business approval | Pass | Sample replay matched expected risk bands for 250 representative records. |
| Findings dispositioned | Findings register with owner, severity, disposition, and rationale | Pass | One medium finding resolved by updating the null-handling rule. |
| Residual risk assessed | Risk register entry or approval comment | Pass | No critical or high residual semantic risk remains. |
Policy Gate and Approval Workflow¶
- Policy gate criteria are documented for this artifact
- Required reviewers have completed semantic validation review
- Required approver has approved release, conditional release, or rework
- Exceptions include approver, rationale, compensating controls, and follow-up date
- Approval record links to NATAegisFlow run ID, artifact version, and evidence location
| Gate | Required Role | Decision | Date | Evidence / Approval Link |
|---|---|---|---|---|
| Semantic Review | QA Semantic Reviewer | Approved | 2026-07-23 | Story attachment: semantic-review-NAF-2026-07-23-018.md |
| Policy Gate | Risk Data Product Owner | Approved | 2026-07-23 | Story approval comment: POLICY-GATE-RISK-218 |
| Release / Handoff | Data Engineering Lead | Complete | 2026-07-23 | Release checklist: REL-24.7-risk-segmentation |
Evidence Package¶
- Evidence attached
- NATAegisFlow output files or report links attached
- Artifact version, patch ID, and source data versions recorded
- Reviewer notes and finding dispositions attached
- Approval record attached
- Evidence location meets access control and retention expectations
Evidence attached: - NAF-2026-07-23-018-summary.json - risk-segment-lineage-export.csv - US-RISK-218-patch-validation.md - POLICY-GATE-RISK-218-approval.txt
Patch Validation¶
- Patch validation complete
- Changed artifacts are compared against the approved baseline
- Regression or replay validation confirms no unintended semantic drift
- Downstream consumers, reports, or operational handoffs are updated if affected
- Follow-up backlog items are created for accepted or deferred findings
Patch validation result: Complete. Replay validation confirmed the patch only changes the approved premium customer segment boundary, and no downstream report columns changed.
