Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR adds recursive list access and stable invitation management, but the current head still contains security-sensitive CI permission and shell-input handling issues, collaboration privacy and authorization gaps, and concrete invitation/list-management failures. These can enable unintended repository actions or data exposure and cause user operations to fail, so the PR is not merge-ready until the high-impact issues are fixed or explicitly accepted.

This test protects the permission boundary that an explicit non-recursive grant on
childsurvives revocation of the recursive grant onparent. The current assertions only checkparentabsence andchild.parentId. If a regression revoked the child grant as well,lists.find(...)returnsundefinedand the failure message points at a null check rather than at lost access.💚 Proposed addition
