# Checklist

> Gate case resolution on a required list of investigation steps, configured per blueprint and tracked per case.

The checklist is a short, auto-numbered list of steps an officer must work through before a case can be resolved.

***

## Configuring a checklist

On a blueprint's **Case content** tab, enable **Checklist** and add items with **+ Add field**. Items are auto-numbered and can be reordered by drag and drop. Didit recommends 5-7 items, enough to standardize an investigation without turning it into busywork.

Toggle **Make checklist optional for case resolution** to let officers resolve a case with incomplete items. Leave it off to make every item mandatory.

Every new case created on the blueprint copies the current checklist items at creation time, later edits to the blueprint's checklist do not retroactively change checklists already running on existing cases.

## Working the checklist

The case page's persistent right rail shows the checklist as "**n / m completed**". Officers check items off as they complete each step; every completion is logged on the case timeline.

## Resolution gating

Attempting to resolve a case with incomplete, non-optional checklist items is blocked with a 400 listing the incomplete item labels, and the Resolve dialog surfaces them inline so the officer knows exactly what is left. Once the blueprint marks the checklist optional, resolution proceeds regardless of checklist state.

<Note>
  The optional flag lives on the blueprint, not per item. Earlier per-item mandatory flags have been replaced by this single blueprint-level toggle, keeping the gating rule unambiguous.
