HLZD Trade Compliance

5 道检查 (4 buyer-side + 1 product-side) + 三态路由，挡住 V0.1 已知的常见制裁实体 / 禁运国家 / 双用途品类。

When to use

调用本 Skill 当用户：

• 每次收海外询盘 —— 一票询盘进来，先跑 compliance，再决定报价 / 屏蔽
• 任何"B 类"以上客户的新询盘 —— 不让 Hezbollah 命中 → 你填了 DHL 单子被海关扣货
• 任何产品涉及 ECCN（加密 / 高端材料 / 化学武器前体）
• 内部合规审计：每月底跑一次全量 buyer/country 抽查

不要调用本 Skill 当：

• 询盘评级 D（已经在 hlzd-inquiry-qualify 拦截）
• 卖家是您的复购客户（已知合规过）
• 法规授权：通过商务部 / 银行 / 律所做正式验证（v0.1 是粗筛，绝对不是法律意见）

How this skill is invoked

# 1. 准备 transaction JSON
cat << 'EOF' > tx.json
{
  "buyer_name": "Aramco Trading Co.",
  "buyer_country": "Saudi Arabia",
  "product": "OCTG casing",
  "hs_code": "730429",
  "end_use_country": "Saudi Arabia",
  "incoterm": "CIF",
  "value_usd": 850000
}
EOF

# 2. 跑合规检查
py scripts/cli.py --input tx.json --pretty

# 3. 生成 Markdown 报告
py scripts/render_report.py < report.json > report.md

输出结构：

{
  "clearance": "CLEARED" | "PENDING_REVIEW" | "BLOCKED",
  "final_action": "Proceed with documentation; periodic re-check required.",
  "rationale": "...",
  "check_results": [...],
  "audit_trail": [...],
  "data_versions": {...},
  "data_source_attribution": [...]
}

cli.py 的 exit code 也作为机器可读的信号：0 = CLEARED / 1 = PENDING_REVIEW / 2 = BLOCKED，方便 CI 拦截。

5 道检查

#	Check	Source	What it does	Default severity
1	ofac_sdn_name_match	data/ofac_sdn.csv (33 entries)	OFAC Specially Designated Nationals 实体的模糊匹配	BLOCK
2	eu_consolidated_name_match	data/eu_consolidated.csv (17 entries)	EU Council Consolidated List (CFSP Decisions)	BLOCK
3	bis_entity_name_match	data/bis_entity.csv (15 entries)	BIS Entity List / Denied Persons List	REVIEW
4	country_embargo_match	lib.COUNTRY_EMBARGOES (12 countries)	Country-Based Sanctions (Iran / NK / Syria / Cuba / Crimea / Donetsk / Luhansk / Venezuela / Belarus / Russia / Myanmar / Zimbabwe)	BLOCK or REVIEW
5	eccn_dual_use_keyword	lib.DUAL_USE_KEYWORDS (15 keywords) + eccn_map (HS→ECCN)	双用途商品粗筛 (加密 / 高端材料 / UAV / 化学武器前体)	REVIEW

每条 check 都生成一条 audit_trail entry（timestamp + version + matched + flags_count），便于合规审计。

v0.1 vs production

v0.1 (现在)	v0.2 (target)
33 OFAC SDN 静态子集	完整 SDN_ENHANCED (1.5 万行) via Treasury API
17 EU Consolidated 静态子集	完整 EU FSF via CFSP RSS feed
15 BIS Entity List 静态子集	完整 BIS via commerce.gov CSV
12 Country Embargo 综合 OFAC + EU	接 OFAC + EU 双独立 feed
15 dual-use 关键词	接 BIS Commerce Control List ECCN 编码库

Clearance 三态路由

                        all_flags 有一 BLOCK?
                       /               \
                yes /                 \ no
                   /                   \
              BLOCKED                  all_flags 有一 REVIEW?
       "DO NOT ship,                  /               \
        escalate to officer"     yes /                 \ no
                                      /                   \
                                PENDING_REVIEW           CLEARED
                          "HOLD + legal review"   "Proceed with documentation"

代码：scripts/check.py:run_compliance_check 内 if any(f.severity == "BLOCK") ... elif REVIEW ... else CLEARED。

    }
  ],
  "metadata": { "rows_loaded": 33, "matches": [...] }

Fuzzy matching algorithm

O(n) 简单匹配 — 每个候选 CSV 行做 4 级：

1. Exact normalized (normalize_name 后完整相等)
2. Bidirectional substring (任一方含另一方 ≥ 6 chars)
3. Token-level share (共享 token 中有 ≥ 1 个 ≥ 6 chars, e.g. "Huawei")
4. Stopword-filtered (去除 industrial / group / company 等泛词避免误命中)

例：

• "Hezbollah Procurement" 匹配 OFAC SDN → "Hezbollah"（exact）→ BLOCK
• "Wagner Military Group" 匹配 OFAC SDN → "Wagner Group"（substring）→ BLOCK
• "Huawei Procurement LLC" 匹配 OFAC + EU + BIS → "Huawei Technologies"（token）→ BLOCK
• "ACME Industrial Imports" 不应命中 "Iran Aircraft Manufacturing Industrial Co"（industrial 被 stopword 过滤）→ clean

Sample integration

嵌入 hlzd-inquiry-qualify (从 5 维评分升级)

把 inquiry-qualify 的合规粗筛替换/补充为正式 hlzd-trade-compliance：

# 在 inquiry-qualify 的 evaluation step 加
import trade_compliance

tx = {"buyer_name": parsed_customer.company_name,
       "buyer_country": parsed_customer.country,
       "product": parsed_product.name,
       "hs_code": parsed_product.hs_code,
       "incoterm": parsed_inquiry.incoterm}

compliance_report = trade_compliance.run_compliance_check(tx)
if compliance_report.clearance == "BLOCKED":
    return "halt_to_compliance_officer"
elif compliance_report.clearance == "PENDING_REVIEW":
    return "review_required"

嵌入 hlzd-customer-due-diligence (替换 OFAC 静态子集)

diligence 当前的 OFAC 用 20 条静态，应替换为合规 Skill：

# diligence 的 evaluate_buyer 加：合规检查
from hlzd_trade_compliance import run_compliance_check

tx = {"buyer_name": buyer["importer_name"], ...}
cr = run_compliance_check(tx)
if cr.clearance == "BLOCKED":
    return halt_result  # 比 5 维评分更暴力

（v0.1 已留接口，v0.2 替换。）

Anti-pattern / Limitations

限制	处置
静态 CSV 仅 80 行	v0.2 接 OFAC/EU/BIS 实时 API
Fuzzy match 可能误判 (e.g. shared "Industrial" 单词)	已用 stopword 过滤；建议复核 BLOCKED 后再用人工致电 buyer
v0.1 不审计 OFAC 50% Rule	提醒客户 ship to 3rd country 时 50% 规则可能触发
没有「de minimis exception」检查	比特币 / 灰关品类需手工
不报 EAR99 vs ECCN 分类本身	ECCN 分类是律师工作
