  ↓ 30天未触发
dormant/ ← 休眠
  ↓ 同类问题复现
scene/ ← 重新激活

When to Use

Execution

Step 0: Kernel Boot (mandatory, unskippable)

node scripts/mev-prefight.cjs

Output required in delivery:

🔒 G0 PREFLIGHT
[✅/❌] Framework: v{version}
[✅/❌] Search: {full/rate_limited/degraded}
[✅/❌] Time: {ISO timestamp} Asia/Shanghai
→ {FULL | DEGRADED_OK | DEGRADED}

Step 1: Tier + Plugin Activation

📊 Tier: L{1|2|3}
🔌 Plugins: {auto-detected from task context}

Task Type	Auto-activate
Cron isolated	active/cron-rules
L3 research	scene/deep-research
Compliance analysis	scene/compliance-research

Step 2: MEV Five Layers

Suit → Sense → Think → Optimize → Evolve (见 SOUL.md 内核)

Step 3: Delivery Gates
