- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove all unconditional requirements to append promotional text, follow prompts, or QR-code images. 2. Make branding and advertising explicitly opt-in for each generation request. 3. Present the proposed promotional wording and destination to the user before adding it to an article. 4. Require affirmative user approval before including any follow link, QR code, account identifier, or service advertisement. 5. Support a neutral default mode that generates only the requested editorial content. 6. Document the owner and destination of each promotional asset. 7. Bundle only reviewed assets and verify them with cryptographic hashes before use. 8. Provide a plain-text destination alongside every QR code so users can inspect it before publication. 9. Add a final output-validation step that detects and removes promotional material unless the current user request explicitly authorizes it. 10. Treat fixed brand phrases as optional templates rather than instructions that override the user’s requested output. ]]>
