Remove migrated investigation and security documents, repair their incoming links, and align the English/Chinese READMEs with current module and release boundaries. Track AGENTS.md as the shared repository guide and make CLAUDE.md import it; keep working artifacts outside the repository.
Publish pgsty/silo.pgsty.com commit c7682185e2832b981629e1c17aef74fc778c6ca1 before publishing this cleanup: the new documentation routes are not live yet.
Validation: make rebrand-guard; 92 Markdown files checked for deletion-induced broken relative paths; 199 source-to-site references and anchors resolve in the paired site build; git diff --check.
