# Phase 2 — Validation Strategy

> Per-phase validation contract for feedback sampling during execution.
> Populated by the planner during plan generation. Each plan's tasks declare automated verification commands or a Wave-0 dependency.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.x (sim + unit + integration) + Playwright 1.x (e2e smoke, PIPE-07) |
| **Config files** | `vitest.config.ts`, `playwright.config.ts` (Phase 1 already shipped both) |
| **Quick run command** | `npm test` (Vitest only — happy-dom env; ~2–4s on warm cache as Phase-2 surface grows) |
| **Full suite command** | `npm run ci` (lint + Vitest + validate:assets + build + check:bundle-split) |
| **Playwright command** | `npm run test:e2e` (= `npx playwright test`; Phase 2 ships the first real e2e) |
| **Estimated runtime** | Vitest ≤8s · Playwright ≤30s · `npm run ci` ≤90s |

---

## Sampling Rate

- **After every task commit:** Run `npm test` (Vitest)
- **After every plan wave:** Run `npm run ci` (full)
- **Before `/gsd-verify-work`:** `npm run ci` AND `npx playwright test` must be green
- **Max feedback latency:** ≤8 seconds for Vitest; ≤30s for Playwright

## Per-Task Verification Map

> Every PLAN task's automated verification command, mapped to a phase REQ-ID and any threat-model entry.

## Wave 0 Requirements

Wave 0 (Plan 02-01) lands BigQty, the Zustand 5 store, the tick scheduler, and the Phase-2 V1Payload schema extension before any vertical slice can run. Until Wave 0 lands, every Wave-1+ task carries a Wave-0 dependency.

- [ ] `src/sim/numbers/big-qty.ts` + `big-qty.test.ts` — BigQty wrapper unit tests
- [ ] `src/sim/numbers/format.ts` + `format.test.ts` — UX-11 thresholds
- [ ] `src/sim/scheduler/clock.ts` + `clock.test.ts` — FakeClock fixture; Date.now() owner
- [ ] `src/sim/scheduler/tick.ts` + `tick.test.ts` — drainTicks, accumulator, CORE-02
- [ ] `src/sim/scheduler/catchup.ts` + `catchup.test.ts` — 24h clamp + negative refusal (CORE-03 + CORE-11)
- [ ] `src/store/store.ts` + `store.test.ts` — Zustand 5 vanilla createStore + 4 slices
- [ ] `src/store/sim-adapter.ts` — slim sim → store adapter (sim never imports the store directly)
- [ ] `src/save/migrations.ts` — extended V1Payload with unlockedPlantTypes / luraBeatProgress / offlineEvents / settings.persistenceToastShown (Phase-2 schema EXTENSION, not v1→v2)
- [ ] `src/save/lifecycle.ts` + `lifecycle.test.ts` — UX-10 hooks (visibilitychange + beforeunload + saveOnSeasonTransition)
- [ ] `src/game/event-bus.ts` — Phaser.Events.EventEmitter singleton (per Phaser 4 React-template pattern)
- [ ] `eslint.config.js` — additional sim-purity rule banning `Date.now`/`setInterval` in `src/sim/**` (defended option; Plan 02-01 Task 3 ships)

*Filled in by Plan 02-01. Plans 02-02..02-05 declare a Wave-0 dependency in frontmatter (`depends_on: [02-01, ...]`).*

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| AudioContext.resume() actually unlocks audio across Chrome / Firefox / Safari / Edge | AEST-07 | Browser autoplay policies vary; Vitest happy-dom does not exercise real audio context. | After Plan 02-02 lands, manually load the dev build in Chrome / Firefox / Safari (last 2 stable). Click Begin. Confirm a console-logged `audioContext.state === 'running'`. |
| Letter prose reads in voice (not as a stat dump) | UX-02 | Tonal verification is a human review; CONTEXT D-17 explicitly calls this out. | Author reviews `/content/dialogue/season1/letter-from-the-garden.ink` against the bible voice; reviewer signs off in Plan 02-05 SUMMARY. |
| Cozy 2–5min growth feels right at playtest | CONTEXT D-08 / D-09 | Subjective pacing — only verifiable by playing. | Solo playtest after Plan 02-05 lands. Adjust per-plant durations if either pace is off; record final values in SUMMARY. |
| Lura's three beats read in voice + warmth-anchor tone | STRY-01 + CLAUDE.md Tone | Tonal verification. | After Plan 02-04 lands, user reads compiled Lura beats in dev build during a real harvest cadence. Sign-off in Plan 02-04 SUMMARY. |
| Tile→DOM coord mapping under Phaser.Scale.FIT | RESEARCH Assumption A5 (MEDIUM) | Layout depends on actual canvas DOMRect; test in non-fullscreen window. | Plan 02-02 Task 2 manual smoke: dev build → click empty tile → seed picker positioned visually over the tile in non-fullscreen + fullscreen. |
| inklecate compiles cleanly on Windows + macOS + Linux | RESEARCH Assumption A6 (MEDIUM) | First real inklecate invocation in the project. | Plan 02-04 Task 1 first run on the dev machine; cross-platform verified post-merge via CI run. |

## Validation Sign-Off

- [x] All tasks have `<automated>` verify or Wave 0 dependencies
- [x] Sampling continuity: no 3 consecutive tasks without automated verify (every task above has a non-empty `Automated Command`)
- [x] Wave 0 covers all MISSING references (Plan 02-01 Tasks 1+2 land all foundations Plans 02-02..02-05 depend on)
- [x] No watch-mode flags (`vitest run`, not `vitest`)
- [x] Feedback latency < 8s for Vitest, < 30s for Playwright
- [x] `nyquist_compliant: true` set in frontmatter (set by the planner after the per-task map filled)

**Approval:** approved (planner)
