Phase 12 — Validation Strategy

Per-phase validation contract for feedback sampling during execution.

---

Test Infrastructure

Property	Value
Framework	Bun test (built-in)
Config file	None — uses bun test directly
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
12-01-01	01	1	COMP-01	manual-only (UI/browser)	—	N/A	⬜ pending
12-01-02	01	1	COMP-02	unit (if delta util extracted)	bun test tests/lib/comparison-deltas.test.ts	❌ W0	⬜ pending
12-01-03	01	1	COMP-03	manual-only (CSS/browser)	—	N/A	⬜ pending
12-01-04	01	1	COMP-04	manual-only (UI state)	—	N/A	⬜ pending

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

---

Wave 0 Requirements

• tests/lib/comparison-deltas.test.ts — stubs for COMP-02 delta computation (optional; skip if deltas stay inlined in React component via useMemo)

Existing bun test infrastructure covers all backend services. This phase is pure frontend — no backend tests are broken.

---

Manual-Only Verifications

Behavior	Requirement	Why Manual	Test Instructions
Candidates display all fields in tabular columns	COMP-01	UI rendering — no backend logic	Open thread with 2+ candidates, toggle compare view, verify all fields visible
Table scrolls horizontally with sticky label column	COMP-03	CSS behavior — requires browser	Narrow viewport to <768px, verify horizontal scroll, verify label column stays fixed
Resolved thread shows read-only view with winner marked	COMP-04	UI state — requires resolved thread	Open resolved thread, toggle compare view, verify winner column highlighted, no interactive elements
Missing weight/price shows dash, not zero	COMP-04	UI rendering for null data	Add candidate with no weight, toggle compare, verify "—" not "0g"

---

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
