# 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
