Phase 7 — Validation Strategy

Per-phase validation contract for feedback sampling during execution.

Test Infrastructure

Property	Value
Framework	Bun test runner (built-in)
Config file	None (uses bun defaults)
Quick run command	bun test
Full suite command	bun test
Estimated runtime	~5 seconds

---

Sampling Rate

• After every task commit: Run bun test
• After every plan wave: Run bun test
• Before /gsd:verify-work: Full suite must be green
• Max feedback latency: 5 seconds

Per-Task Verification Map

Task ID	Plan	Wave	Requirement	Test Type	Automated Command	File Exists	Status
07-01-01	01	1	UNIT-01	unit	bun test tests/routes/settings.test.ts	No — Wave 0	⬜ pending
07-01-02	01	1	UNIT-02	unit	bun test tests/lib/formatters.test.ts	No — Wave 0	⬜ pending
07-01-03	01	1	UNIT-03	unit	bun test tests/routes/settings.test.ts	No — Wave 0	⬜ pending

Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky

---

Wave 0 Requirements

• tests/lib/formatters.test.ts — formatWeight with all 4 units, null handling, precision
• tests/routes/settings.test.ts — settings API for weightUnit key (GET/PUT)

Existing test infrastructure (bun test, helpers/db.ts) covers framework setup.

Manual-Only Verifications

Behavior	Requirement	Why Manual	Test Instructions
Unit toggle renders in TotalsBar	UNIT-01	UI component rendering	Open app, verify g/oz/lb/kg toggle visible in TotalsBar
All weight displays update on unit change	UNIT-02	Visual verification across 8 components	Switch unit, check ItemCard, CandidateCard, CategoryHeader, SetupCard, setup detail, collection route
Setting persists across browser refresh	UNIT-03	Browser session state	Select "oz", refresh page, verify still shows "oz"

---

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 < 5s
• nyquist_compliant: true set in frontmatter

Approval: pending
