+A coffee sample can be delegated to a laboratory. The delegation creates and

+
+<ul style="margin:0.65rem 0 1rem 1.1rem; padding-left:1rem; list-style-type:disc;">

+</li>
+<li style="margin:0.38rem 0;">compliance check against the target purchase/sale line thresholds.

+<li style="margin:0.38rem 0;">the target line quality thresholds;

+<li style="margin:0.38rem 0;">cupping session decisions, including <code>re-cup</code> and <code>rejected</code>.
+</li>
+</ul>
+
+The sample exposes a quality status (`pending`, `pass`, `warning`, `fail`) and
+a recommended decision (`approve`, `re-cup`, `reject`). The `Evaluate quality`
+button applies the recommendation: approval, rejection or review when the
+sample must be cupped again.
+
+These features remain under `Active coffee compatibility` and do not add a
+cross-flow blocking rule for non-coffee flows.
