+## Current Milestone: v1.1 Hardening & Validation
+
+**Goal:** Close every open concern from v1.0 — real-world runtime validation, UX tech debt, and Nyquist-compliant validation track — to ship a confidence release.
+
+**Target features:**
+- Real-world Intune tenant runtime validation (.intunewin byte-level + `pnputil` under SYSTEM context)
+- Live browser verification of PRNT-03 Alpine.js IP→port auto-derivation
+- Driver dropdown refresh after new driver upload (no manual page reload)
+- UI links to individual script downloads on printer detail page
+- Nyquist-compliant VALIDATION.md retro-fitted across all 7 v1.0 phases
+- First real-world deployment + structured user feedback capture
+
 ## Current Focus
 
-v1.0 shipped. Next up: v1.1 planning — focus on real-world runtime validation (Intune tenant, SYSTEM-context `pnputil`) and fixing carryover tech debt (driver dropdown refresh, script download UI, Nyquist validation).
+v1.1 — Hardening & Validation. No new features; pure quality, validation, and rollout milestone.
