| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Safekeeping role | custody materials ask who controls or safeguards assets for a regulated adviser or fund context | identify custodian role and account relationship before making custody claims | private contractual terms and final adopted rule text |
| Recordkeeping role | transfer-agent materials focus on ownership records, forms and service-provider disclosures | separate record maintainer from wallet holder and trading venue | future amendments, final compliance dates and private issuer arrangements |
| Tokenization model | SEC tokenized-securities material distinguishes issuer-sponsored and third-party tokenization models | record whether the token maps to issuer records or a third-party promise | bankruptcy risk, contractual rights and offchain reconciliation details |
| Trading venue role | Innovation Exemption materials address a trading model rather than general custody or issuer rights | avoid treating venue relief as a universal asset-ownership claim | conditions of relief, eligible venue status and future Commission action |
| Stop condition | an RWA article is unsafe if custody, recordkeeping, trading and ownership rights are blurred | pause until the source, legal role, token model and user-facing rights document are separated | final rulemaking, product eligibility and private account terms |

控制说明
1. Safekeeping role
这一项要求读者把公开来源翻译成操作规则。这里的含义是：custody materials ask who controls or safeguards assets for a regulated adviser or fund context。可执行动作是：identify custodian role and account relationship before making custody claims。仍然未知的是：private contractual terms and final adopted rule text。因此本文不会把未知部分包装成收益承诺、牌照承诺、审批保证、安全保证、恢复保证、平台排名或价格暗示。
2. Recordkeeping role
这里的含义是：transfer-agent materials focus on ownership records, forms and service-provider disclosures。可执行动作是：separate record maintainer from wallet holder and trading venue。仍然未知的是：future amendments, final compliance dates and private issuer arrangements。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
3. Tokenization model
这里的含义是：SEC tokenized-securities material distinguishes issuer-sponsored and third-party tokenization models。可执行动作是：record whether the token maps to issuer records or a third-party promise。仍然未知的是：bankruptcy risk, contractual rights and offchain reconciliation details。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
4. Trading venue role
这里的含义是：Innovation Exemption materials address a trading model rather than general custody or issuer rights。可执行动作是：avoid treating venue relief as a universal asset-ownership claim。仍然未知的是：conditions of relief, eligible venue status and future Commission action。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
5. Stop condition
这里的含义是：an RWA article is unsafe if custody, recordkeeping, trading and ownership rights are blurred。可执行动作是：pause until the source, legal role, token model and user-facing rights document are separated。仍然未知的是：final rulemaking, product eligibility and private account terms。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
仍需明确的未知项
- private contractual terms and final adopted rule text
- future amendments, final compliance dates and private issuer arrangements
- bankruptcy risk, contractual rights and offchain reconciliation details
- conditions of relief, eligible venue status and future Commission action
- final rulemaking, product eligibility and private account terms
实用结论
SEC custody 与 transfer-agent 材料不能被压缩成同一条 tokenized-asset rule。SEC 有面向 advisers/funds 的 crypto custody proposal statement、Transfer Agent Rules proposal page，以及 staff tokenized-securities taxonomy material。实用边界是：区分谁保管资产、谁维护 ownership records、采用哪一种 tokenization model、收集哪些 investor data，以及哪一份 rulemaking 或 statement 对用户角色真正有约束力。 本文停在证据边界内，帮助读者决定下一步核验什么，而不是把公开文档改写成私人账户、钱包、API key、池子路径、稳定币余额、代币化资产或政策框架在任何未来条件下都能成功的承诺。
