+## 17. Approved feature-branch redesign delivery
+
+The user approved `docs/ZARINPAL-REDESIGN-AMENDMENT.md` on 2026-08-20 and required the work to remain on `feature/zarinpal-dashboard-redesign` until a separately running preview is reviewed.
+
+Build order:
+
+1. Extend the backend contract for four latest complete period windows, terminal-scoped runs, payment history, and routed transaction evidence.
+2. Generate the TypeScript contract and add shadcn-svelte/Lucide foundations.
+3. Replace the single-page dashboard with the shared routed shell and URL-backed controls.
+4. Deliver overview, transaction, performance, fee, peer, methodology, and detail routes as thin vertical slices.
+5. Verify the isolated feature instance on alternate ports, then wait for explicit merge approval.
+
+The current instance remains untouched while the feature preview uses API port `8081` and frontend port `5174`.
