+# Phase 1 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | vitest (Vite-native, shared backend + frontend per CLAUDE.md) |
+| **Config file** | none — Wave 0 installs vitest + workspace config |
+| **Quick run command** | `pnpm vitest run --changed` |
+| **Full suite command** | `pnpm vitest run` |
+| **Estimated runtime** | ~30 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `pnpm vitest run --changed`
+- **After every plan wave:** Run `pnpm vitest run`
+- **Before `/gsd-verify-work`:** Full suite must be green
+- **Max feedback latency:** 60 seconds
+
+---
+
+## Per-Task Verification Map
+
+> Populated by the planner against the final task IDs. Each phase success criterion maps to at least one automated or manual verification below.
+
+| Success Criterion | Requirement | Verification approach | Test Type |
+|-------------------|-------------|-----------------------|-----------|
+| SC1 — OIDC login lands on home, no Fastmail creds | AUTH-01 | E2E: unauthenticated request to protected route 302→Authelia; authenticated session reaches home | manual (real Authelia) + integration (middleware mounted) |
+| SC2 — Sessions persist across browser restart | AUTH-02 | Integration: signed JWT session cookie issued; refresh-token interval configured; unit test cookie attrs (httpOnly, same-site, maxAge) | integration + manual |
+| SC3 — Stable distinct member color | AUTH-03 | Unit: color assignment is deterministic round-robin by join order, persisted on user row keyed by oidc_iss+oidc_sub, unchanged on re-login | unit |
+| SC4 — Broker fetches + caches ≥1 real event | CAL-01 | Integration: broker PROPFIND discovers collections, REPORT returns VEVENT, parsed + written to cache table (raw blob + dtstart_utc/date); all-day DATE handling unit-tested | integration + manual (real Fastmail) |
+| SC5 — CAL-08 go/no-go documented | CAL-08 | Manual: spike confirms app password reads shared + personal collections; decision recorded in a committed doc | manual (decision artifact) |
+
+*Status tracked per task by the planner. Status legend: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

+
+## Wave 0 Requirements
+
+- [ ] `vitest` + workspace test config installed (no framework exists — greenfield)
+- [ ] Shared test fixtures: in-memory/throwaway MariaDB or test schema for Drizzle integration tests
+- [ ] Fastmail CalDAV fixtures: captured raw VEVENT samples (timed + all-day) for offline parser unit tests
+- [ ] Crypto helper test vectors for AES-256-GCM encrypt/decrypt round-trip
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Authelia OIDC end-to-end login | AUTH-01 | Requires real Authelia + Pangolin topology; no mock substitutes for redirect/cookie behavior | Reach public URL → redirected to Authelia → authenticate → land on home with no Fastmail prompt |
+| Session persistence across restart | AUTH-02 | Browser-restart behavior not unit-testable | Log in, fully close browser, revisit URL → no re-login |
+| Real Fastmail event fetch + cache | CAL-01 | Requires real app password + live calendar | Run broker against Lucas's account → confirm ≥1 event row cached |
+| CAL-08 personal-calendar ACL spike | CAL-08 | Spike produces a human go/no-go judgement | Confirm app password reads shared + personal collections via PROPFIND/REPORT; record GO/NO-GO + fallback |
+| Pangolin SSE pass-through smoke test | (D-08, de-risks Phase 4) | Idle-timeout behavior only observable over real public URL | Open long-lived SSE endpoint over Pangolin URL ≥5 min → confirm stream not cut |
+
+---
+
+## Validation Sign-Off
+
+- [ ] All tasks have an automated verify or a Wave 0 dependency, or are listed under Manual-Only with justification
+- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
+- [ ] Wave 0 covers all MISSING references
+- [ ] No watch-mode flags
+- [ ] Feedback latency < 60s
+- [ ] `nyquist_compliant: true` set in frontmatter once planner maps task IDs

+**Approval:** pending
