Approving a rule change

Ce contenu n’est pas encore disponible dans votre langue.

In short

Every rule change is made by one person and accepted by another: this is called maker–checker, or the four-eyes principle. A rule author tunes the rule; you, the approver, check the change and approve or reject it. Approving doesn’t make it run. You then decide when it goes live: straight away with Make live, or after a Shadow test that shows what it would flag without raising alerts.

Who can do it: you need rules.approve. In the built-in roles that is the Rule approver and the MLRO / Compliance officer. You can never approve a version you wrote yourself.

How to find changes waiting for you

On the Rules screen, select the Needs attention tab. It lists every rule with a version awaiting approval or a shadow test running. Rows with a change waiting show N awaiting approval in gold.
Open the rule. In the Versions panel on the right, a version waiting for you is marked Awaiting approval and is already expanded so you can read it.

The Versions list

Every version of the rule is listed, newest first. Each row shows:

Item	Meaning
v1, v2, …	The version number
State	Draft (saved, not sent for approval), Awaiting approval, Approved or Rejected
live (green)	This version is the one running and raising alerts
shadow (gold flask)	This version is being shadow-tested
Author and date	Who wrote it, and when. Versions installed with a pack show Pack
approved by / rejected by	Who decided it
The line underneath	The author’s change note. Select it, or the version number, to expand the full definition: parameters, logic, aggregates and the analyst explanation

What to check before approving

You are the control. Read the change as an examiner would:

The change note. Does it say what changed and why, with evidence: a review of recent alerts, a typology bulletin, a ticket number? “Adjusted threshold” is not enough.
The difference. Expand the new version and the live version and compare the parameters, severity and score box by box. Is the change what the note says, and nothing more?
The direction. A change that reduces alerts (a higher threshold, fewer channels, a lower severity) can be right, or can hide a problem. It needs the strongest evidence. See Rules and versions.
The effect on the queue. Will this create far more alerts than your analysts can work? If you’re unsure, approve it and shadow test it before making it live.
The author. It must be someone else. On a version you wrote yourself, Approve is greyed out, with the tooltip You wrote this version; someone else must approve it. Ask another approver.

How to approve a version

Open the rule and find the version marked Awaiting approval in Versions.
Select Approve. A panel titled Approve version opens, showing the author’s change note.
Under Approval note (optional), add anything worth recording, for example Agreed. Review again after month-end volumes.
Select Approve.

The version is now Approved, and its logic is frozen: its expression, aggregates, parameters, severity, score and action can never change again. It is not running yet.

If the version is yours, approving is refused with a version must be approved by someone other than its author. The database enforces this too, so no one can get around it.

How to reject a version

Select Reject on the version. A panel titled Reject version opens.
Under Why reject, tell the author what is missing or wrong. This is required (at least 3 characters). For example: Threshold too high for agent accounts; check last quarter’s cash-in STRs first.
Select Reject.

The version is marked Rejected and stays on record. It can’t be resubmitted: the author tunes the rule again, which creates a new version.

How to make an approved version live

Approved versions that aren’t live show two buttons:

Shadow test: run it on live traffic next to the live version, recording hits but raising no alerts. Use this when you’re not sure of the effect. See Shadow mode.
Make live: it replaces the live version straight away. Its hits raise alerts from now on.

Select Make live. The version is marked live, and the running system picks it up within about 15 seconds. The previous live version stays Approved on record, so every alert it raised can still be explained and you can return to it.

How to roll back

If a change causes problems, open the rule, find the previous version in Versions (it is still Approved) and select Make live. No new approval is needed, because it was already approved. The change is recorded in the audit log like any other deployment.

Everything is audited

Each decision is written to the audit log with your name, the time, where you were connected from and your note: rule_version.approve or rule_version.reject, and rule.deploy for Shadow test and Make live, with what was in each slot before.

Using the API instead

The same steps are POST /api/v1/rule-versions/{id}/approve or /reject, and POST /api/v1/rules/{id}/deploy with slot set to shadow or active (live). See the Rules API.
