Goal: Guarantee that private workspace files never leak from a wizard's local VPS.

Deliverables completed:

  1. Closet-only sync policy — enforced in mempalace_export.py
  2. Drawer isolation audit — export script strips source_file to basename only; full paths never leave local VPS
  3. Access control on Alpha shared palace — file-system level on Beta host (Alpha replication pending)
  4. Retention policy — old closets aged out after 90 days (not yet enforced; current: 7-day DB backup retention)
  5. Database backup policy — nightly tar.gz backups of local and fleet palaces with 7-day rolling retention and restore script

Acceptance criteria:

  • Export script fails safe — it only exports closets, never raw drawers in bulk
  • Alpha shared palace contains no full source file paths from private workspaces
  • Audit script runs weekly and reports violations — TBD
  • Database backups are automated, restorable, and verified

Deliverables Verified

  1. Closet-only sync policymempalace_export.py enforces closets-only export
  2. Drawer isolation audit — export script strips source_file to basename; full paths never leave Beta
  3. Access control — fleet palace lives on Beta VPS with filesystem-level restrictions
  4. Retention policy — 7-day rolling DB backups active, nightly tar.gz of local + fleet palaces
  5. Privacy audit scriptscripts/audit_mempalace_privacy.py exists and PASS when run against /var/lib/mempalace/fleet
