## Domain analysis and decisions

### Purpose and critical data (`purpose`)

Identify consumers, critical elements, error consequences, and acceptable risk.

> Enter project evidence, conclusion, and owner.


### Dimensions and versioned rules (`rules`)

Fix population, denominator, exceptions, threshold, measurement point, approval, and effective date per rule.

> Enter project evidence, conclusion, and owner.


### Profiling and baseline (`baseline`)

Record sampling windows and defect rates for stock, flow, source, and consumption points.

> Enter project evidence, conclusion, and owner.


### Business impact and priority (`impact`)

Link defect samples to loss, decision risk, and remediation benefit.

> Enter project evidence, conclusion, and owner.


### Root cause and recurrence test (`root_cause`)

Test root-cause hypotheses with process, interface, or source evidence.

> Enter project evidence, conclusion, and owner.


### Prevention detection and correction (`prevention`)

Prevent at creation, detect in flow, and audit historical repair.

> Enter project evidence, conclusion, and owner.


### Issue closure and scorecard (`scorecard`)

Set SLA, trends, exception expiry, retesting, and business benefit.

> Enter project evidence, conclusion, and owner.


### Gates and acceptance (`acceptance_evidence`)

Verify root-cause control, recurrence trend, and residual exceptions with evidence.

> Enter project evidence, conclusion, and owner.


## Working registers

### Quality Rules (`rules`)

Maintain testable quality rules and approved thresholds.

| Rule (`rule`) | Definition (`definition`) | Denominator (`denominator`) | Threshold (`threshold`) | Owner (`owner`) | Version (`version`) | Evidence (`evidence`) |
| --- | --- | --- | --- | --- | --- | --- |
|   |   |   |   |   |   |   |

### Quality Issues (`issues`)

Track baselines, root causes, corrections, and closure evidence.

| Rule (`rule`) | Baseline (`baseline`) | Impact (`impact`) | Control (`control`) | Owner (`owner`) | Status (`status`) | Evidence (`evidence`) | Review date (`review_date`) |
