+Live Attribute references use a stable Attribute ID and read the authoritative
+loadout total that the builder captures for the evaluation pass. Percentage
+Attributes retain their displayed units, so an expression that applies a
+coefficient to a percentage divides the Attribute value by 100. Evaluation
+fails when the loadout does not supply a referenced Attribute; the runtime does

+Continuous restoration resolves the outcome's total when the branch activates,

+Activations create independent streams, overlapping streams add, and restoration
+above the resource maximum is lost when it occurs. The runtime integrates
+delivery at event and expiry boundaries before processing the event at that
+timestamp, which keeps results independent of an arbitrary tick interval.

 Periodic behavior requires an interval in the reducer. The runtime does not
 infer a one-second cadence from missing data. A mechanic with an unknown cadence
