+
+## v1.0 MVP (Shipped: 2026-03-27)
+
+**Phases completed:** 4 phases, 18 plans
+**Timeline:** 2026-03-26 → 2026-03-27 (2 days)
+**Stats:** ~2,746 LOC TypeScript/TSX, 101 files, 73 commits
+
+**Key accomplishments:**
+1. Vite 6 + React 18 + TypeScript scaffold with Tailwind v4, Vitest, and zero-error dev server
+2. Backend Schema Registry as single source of truth — drives form rendering, Zod validation, and config generation for Azure Blob, S3, S3-compatible
+3. 4 pure generator functions (rclone.conf, Intune install/detection, RMM script) — 61 tests, UTF-8 no-BOM, SYSTEM-context safe
+4. Multi-step wizard (backend selection → config → deployment options) with full back-navigation and no data loss — 87 tests GREEN
+5. Review + download + security layer — live preview, security gate, individual downloads, ZIP bundle, clipboard copy — 98 tests GREEN
+6. Pure client-side: no backend, no localStorage writes, credentials never leave the browser
+
+**Tech debt deferred to v1.1:**
+- `scriptTargets` collected in DeploymentStep but ignored by ReviewStep (all output blocks render unconditionally)
+- ReviewStep missing explicit Back button (UX inconsistency)
+- Backend list hardcoded in BackendSelectionStep, not driven by BACKEND_REGISTRY keys
+- `BackendFormValues<T>` dead export in src/schemas/index.ts
+- `act()` warnings in BackendSelectionStep tests
