Phase 3 — Validation Strategy

Per-phase validation contract for feedback sampling during execution.

Test Infrastructure

Property	Value
Framework	{pytest 7.x / jest 29.x / vitest / go test / other}
Config file	{path or "none — Wave 0 installs"}
Quick run command	{quick command}
Full suite command	{full command}
Estimated runtime	~{N} seconds

---

Sampling Rate

• After every task commit: Run {quick run command}
• After every plan wave: Run {full suite command}
• Before /gsd-verify-work: Full suite must be green
• Max feedback latency: {N} seconds

Per-Task Verification Map

Task ID	Plan	Wave	Requirement	Threat Ref	Secure Behavior	Test Type	Automated Command	File Exists	Status
{N}-01-01	01	1	REQ-{XX}	T-{N}-01 / —	{expected secure behavior or "N/A"}	unit	{command}	✅ / ❌ W0	⬜ pending

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

---

Wave 0 Requirements

• {tests/test_file.py} — stubs for REQ-{XX}
• {tests/conftest.py} — shared fixtures
• {framework install} — if no framework detected

If none: "Existing infrastructure covers all phase requirements."

---

Manual-Only Verifications

Behavior	Requirement	Why Manual	Test Instructions
{behavior}	REQ-{XX}	{reason}	{steps}

If none: "All phase behaviors have automated verification."

---

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 < {N}s
• nyquist_compliant: true set in frontmatter

Approval: {pending / approved YYYY-MM-DD}
