+# Phase 14 — Validation Strategy
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | Go `testing` (stdlib) |
+| **Config file** | `backend/go.mod` |
+| **Quick run command** | `cd backend && go test ./templates/... -count=1` |
+| **Full suite command** | `cd backend && go test ./... -count=1` |
+| **Estimated runtime** | ~5 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** `cd backend && go test ./templates/... -count=1`
+- **After every plan wave:** `cd backend && go test ./... -count=1`
+- **Before `/gsd-verify-work`:** Full suite must be green

+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Animated background renders with 35 floating logo icons visible in browser | AUTH-UI-01/02 | CSS animation + visual rendering cannot be asserted in Go template tests | `cd backend && just run` → visit http://localhost:8080/login → confirm floating logos animate across gradient background |
+| Google button renders with Roboto Medium font and correct pill shape | AUTH-UI-03 | Font loading (Google Fonts CDN) cannot be tested in-process | Visit http://localhost:8080/login → inspect gsi-material-button renders with Roboto font and 20px border-radius pill shape |
+| HTMX swap on login/signup form submission (inline error, no full reload) | AUTH-UI-01/02 | Requires browser + HTMX JS execution | Submit invalid credentials on /login → error appears inline within card without full page reload |
+
+---
+
+## Sign-Off
+
+- **Automated:** 14/14 tests green (`cd backend && go test ./... -count=1`)
+- **Manual:** 3 items verified at human-verify checkpoint (2026-05-16, approved)
+- **Nyquist compliant:** Yes — all requirements have automated coverage; manual items are visual/browser-only behaviors that cannot be machine-tested
