Fairness readings computed on modeled data demonstrate the instrument, not a real audit result. The grid below is produced by the same code that would run against a real population; the population underneath is modeled.

Access revocation on exit
Revokes system access on the leaving date. Included here because a premature revocation affects a person materially and the error rate is not uniform across populations.
Who is accountable, and what the oversight actually is
Named, with the measure written out rather than implied by a role title.
Regulatory position
How this decision is classified and what the affected person can see.
Selection rate by cohort, by period
Impact ratio against the reference cohort. A cell with no reading means the sample was too small to compute one — it is not a pass.
| Cohort | Reference |

Alarms on this decision point
Each with the action recorded against it and the person who owns it.
Appeals against this decision
Every contest recorded, with who reviewed it, how long they spent and what changed.

| APL-0013 | EMP-07740 employee · DE | Access was revoked four days before the agreed leaving date, blocking handover. | Yusuf Adeyemi Chief Technology Officer | 6 / 24 hr | 15 min | Overturned Termination date in the HR system had not been updated after an extension. Access restored within six hours and an incident was raised against the date synchronization. | IT1A-1020#1 | Closed |
The impact ratio is the cohort’s selection rate divided by the reference cohort’s. For a decision where being selected is the benefit, the threshold is four-fifths and a ratio below it is the alarm. For a decision where being selected is the harm, the test is inverted and a ratio above 1.25 is the alarm. Both are stated on the reading rather than left to the reader.
A reading is only computed when the cohort and the reference cohort each carry at least thirty people and at least five events. Below that, no ratio is produced and the cell stays empty. This is the single most common way a fairness dashboard misleads — a small cohort producing a comfortable number — and it is refused here by construction.
This decision runs in US, UK, DE, SG, AU. Local law shapes what may be measured: where a works council agreement or a local statute restricts cohort analysis, the exclusion is recorded in the monitoring status rather than silently applied.
