 ## Risky Or Sensitive Areas
 
 - ERP write boundaries and reconciliation after uncertain responses.
+- Multi-parent shared-child enumeration and sequential write-stop boundaries.
+- External Webhook secrecy, one-attempt delivery uncertainty, and privacy projection.
 - Attachment encryption, OSS network validation, and passenger workbook normalization.
 - Cross-file release version and hash synchronization.
 - Concurrent worktree ownership and canonical document integration.
