Add a second-level project management directory to match the requested navigation hierarchy. Preserve page permissions and legacy URLs, and migrate existing role grants to include the new ancestor. User will validate after integration.
Separate cross-team selection from attribution maintenance and apply the same scope to options, history filters and writes. Add an opt-in tenant permission without granting existing roles.
Protect authorization mutation paths against self-grants, validate tenant targets and links, and include menu ancestors atomically. Cover role union, revocation, mobile writes and administration boundaries with regression tests.
Add the Project navigation group alongside Market, Production and Quality. Preserve existing leaf IDs and role grants while migrating the menu hierarchy, keep legacy URLs redirecting, and align frontend/backend menus.
Add tenant-scoped teams and projects, order attribution across four businesses, conversion inheritance, scoped statistics and audited reassignment. Reuse existing Web and mobile UI patterns; team regions and hospitals remain informational.
Include incremental SQL and isolated regression coverage. Actual MySQL and browser/WebView integration validation remains pending; relates to issue #13.
