- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Introduce a distinct variable such as `DATA_CLEANER_LICENSE_KEY` for subscription verification. 2. Never transmit MiniMax, DeepSeek, or other provider credentials to the licensing service. 3. Validate license tokens using a narrowly scoped, revocable token issued specifically by YK Global. 4. Make remote license verification explicit in the documentation and disclose the destination, transmitted fields, purpose, and retention policy. 5. Obtain user consent before the first network verification where the runtime platform requires it. 6. Avoid logging authorization headers or complete license tokens on the client and server. 7. Add automated tests asserting that `DATA_CLEANER_API_KEY` is only sent to the selected AI provider. 8. Update the README's local-processing statement so it accurately describes all network operations. ]]>
