+## 3.9 主機 Evidence Intake Preflight
+
+S2.18 將主機 evidence 進人工 review 前的預檢條件顯示成只讀規則。這一層只回答「未來 evidence 送進來前要先擋什麼」，不接收 payload、不驗收 evidence、不推進 counters。
+
+| 順序 | 預檢項目 | 拒收 / 隔離條件 | 目前狀態 |
+|------|----------|------------------|----------|
+| 1 | Metadata pointer only | 缺 redacted metadata pointer | `preflight_ready_not_executed`；received=0、accepted=0 |
+| 2 | Collection order match | 跳過 S2.17 前置依賴 | `dependency_check_waiting_evidence`；received=0、accepted=0 |
+| 3 | Scope before scan | scan evidence 沒有 scope boundary | `waiting_scope_evidence`；received=0、accepted=0 |
+| 4 | Owner before host change | SSH / update / tuning / blocking evidence 缺 owner decision pointer | `waiting_owner_decision_pointer`；received=0、accepted=0 |
+| 5 | Credential plaintext blocked | 出現帳密、token、private key、session 或憑證明文 | `plaintext_credential_collection_forbidden`；received=0、accepted=0 |
+| 6 | Raw payload blocked | 出現完整掃描 raw output、未脫敏 finding、host dump 或 log bundle | `raw_payload_collection_forbidden`；received=0、accepted=0 |
+| 7 | Frontend counters frozen | 前端嘗試推進 received / accepted | `frontend_counter_transition_forbidden`；received=0、accepted=0 |
+
+每個 check 都固定 `display_mode=intake_preflight_only`、`raw_payload_allowed=false`、`secret_value_collection_allowed=false`、`runtime_execution_authorized=false`、`action_buttons_allowed=false`、`not_authorization=true`。
+
+這個 preflight board 不代表已收到任何主機 evidence，也不代表已進人工 review。真正收件仍需要脫敏 evidence pointer、owner decision 與後續人工驗收。
