+# Phase 19 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+

+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | vitest (existing) |
+| **Config file** | teressa-copeland-homes/vitest.config.ts (or package.json scripts) |
+| **Quick run command** | `cd teressa-copeland-homes && npm run type-check` |
+| **Full suite command** | `cd teressa-copeland-homes && npm run build` |
+| **Estimated runtime** | ~30 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `npm run type-check`
+- **After every plan wave:** Run `npm run build`
+- **Before `/gsd:verify-work`:** Full build must succeed with no type errors
+- **Max feedback latency:** 30 seconds
+
+---

+## Wave 0 Requirements
+
+- [ ] `teressa-copeland-homes/src/app/portal/(protected)/templates/page.tsx` — stub (list page)
+- [ ] `teressa-copeland-homes/src/app/portal/(protected)/templates/[id]/page.tsx` — stub (editor server component)
+- [ ] `teressa-copeland-homes/src/app/portal/(protected)/templates/[id]/_components/TemplatePageClient.tsx` — stub
+- [ ] `teressa-copeland-homes/src/app/portal/(protected)/templates/[id]/_components/TemplatePanel.tsx` — stub
+- [ ] `teressa-copeland-homes/src/app/api/templates/[id]/ai-prepare/route.ts` — stub
+- [ ] `teressa-copeland-homes/src/app/api/templates/[id]/fields/route.ts` — stub
+- [ ] `teressa-copeland-homes/src/app/api/templates/[id]/file/route.ts` — stub
+
+*Existing infrastructure (vitest, next build) covers the test framework — Wave 0 only needs file stubs.*
+

+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| FieldPlacer drag-drop works in template mode | TMPL-05 | Browser interaction | Open `/portal/templates/[id]`, drag a field onto the PDF, verify it snaps to position |
+| AI Auto-place triggers and places fields | TMPL-06 | HTTP + browser | Click "AI Auto-place Fields", wait for spinner, verify fields appear on PDF |
+| Role labels accepted (no email validation) | TMPL-07 | Browser interaction | Type "Lender" as a role label, verify no error toast |
+| Text hint persists across reload | TMPL-08 | Browser + reload | Set hint on text field, save, reload, verify hint displays as placeholder |
+| Save persists to DB and survives reload | TMPL-09 | Browser + reload | Save template, reload page, verify all fields and roles are restored |
+
+---
+
+## Validation Sign-Off
+
+- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
+- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
+- [ ] Wave 0 covers all MISSING references
+- [ ] No watch-mode flags
+- [ ] Feedback latency < 30s
+- [ ] `nyquist_compliant: true` set in frontmatter

+**Approval:** pending
