Give ADR 0313 a home in design 47, the delivery budget it extends

The knowledge base's whole-set cited rule (to-be 55, ADR 0313's own review)
refuses to accept a record nothing cites. Design 47 already builds on
ADR 0282's delivery budget, which ADR 0313 extends with the operator's
wider fix-time target, so it is the record's home.

+*A wider measure, around the delivery budget (2026-10-12, ADR 0313, extending ADR 0282).* The delivery budget
+above runs from the merge; the operator's own target is wider, the **fix time**, which runs from an issue's
+first move to `fixing` to the moment its last fix is delivered. Each issue's class carries a **fix budget** too
+(five minutes leaf, ten core, the delivery budget's own figures), and the tracker splits a fix time into four
+phases — implementing, review, checks, and merge to running (the delivery time above) — so a fix over its
+budget is said loud, naming its longest phase, and clears at the next fix of its class delivered within budget.
+The delivery budget stays as written: a measure inside the fix budget, not replaced by it.

 **What changes in the walk.**
 
 - **A lone merge is cut at once**: no batch assembling, and no member of its delivery group still unmerged.
