Memento Native 2.2.0

Highlights

• Settings opens instantly: storage usage is computed in the background with a cache instead of blocking the window (10+ seconds on large archives)
• New storage controls: custom retention period (1-365 days), max storage size with automatic oldest-first cleanup, and Time Machine backup exclusion
• Clipboard capture never stores secrets copied from password managers (concealed-clipboard filtering)
• Storage maintenance now runs continuously (at launch and every 6 hours), not only at app start

Added

• Custom… option in Keep data with a 1-365 day field
• Max storage size (GB) setting: oldest recordings are deleted automatically when total usage exceeds the cap (0 = no limit, default)
• Exclude from Time Machine backups setting (default on)

Changed

• Storage usage in Settings and the Statistics dialog is computed off the main thread with a 5-minute cache
• Storage directory permissions tightened to owner-only (0700)
• Retention and the size cap run in one background maintenance pass every 6 hours with overlap protection

Fixed

• Settings window no longer freezes on open with large storage directories
• Clipboard capture skips content marked concealed/transient by password managers
• Database schema migrations no longer log errors on every launch
• Foreign key constraints are now enforced on write connections (strict referential integrity for newly created databases)

Verification

• swift test in MementoCapture: 30 tests, 0 failures (24 new tests in this release)
• swift build -c release clean for both MementoCapture and MementoTimeline
• Every change implemented test-first with independent spec- and code-quality review
