Move timer and appearance preferences between Macs through a versioned JSON file in General settings. Import shows current and proposed values and requires Apply preferences; Cancel makes no change. Export uses built-in icons and private file permissions.

The transfer schema carries only portable preferences. Safety policy, startup choices, triggers, hotkeys, permissions, local assets, history, current holds and durable Stop state stay on the destination Mac. Import reads at most 64 KB from a regular file and rejects unsupported versions, invalid choices and inconsistent duration presets. Failed persistence leaves the current preferences intact.

Validation passed: 682 direct Swift tests, 633 MAS Swift tests, 105 release tests, 16 MAS bundle checks, 43 website tests, strict formatting and local Qlty. Tests cover malformed and oversized files, foreign policy keys, export permissions, persistence failure, Stop/hold preservation and mounted Apply/Cancel controls. The rendered preview was inspected. Native file panels remain unverified because desktop access returns cgWindowNotFound.

The manual-fixture isolation commit is reused from #101.

Summary by CodeRabbit

• New Features
  • Export and import preference files from General settings. Imports show a preview of changes before applying, and can be canceled without changing preferences.
  • Preference files include timer and appearance choices. Safety settings, automation behavior, local assets, and active stop or pause states remain unchanged.
• Documentation
  • Added guidance on preference file export, import, and validation limits.

Integration verification against the reviewed dev/m2 throughput change passed 700 direct and 651 MAS Swift tests, plus release/bundle/web checks. The combined source tree was captured before restoring this unchanged reviewed PR head.

Walkthrough

The change adds JSON export and import for portable settings. Imported profiles are validated and previewed before application. Local settings and files remain outside the profile. Tests cover profile validation, file operations, application, and preview actions.

Changes: Settings profile transfer

Layer / File(s)	Summary
Profile data, validation, and file operations Sources/DilatedUI/Settings/SettingsProfile.swift	SettingsProfile captures portable preferences, validates profile data, reads and writes bounded JSON files, applies profile values, and describes settings differences.
Transfer and apply flow Sources/DilatedUI/Settings/SettingsTransfer.swift, Sources/DilatedUI/AppModel.swift, Sources/DilatedUI/Settings/SettingsWindow.swift	The General settings page adds Export and Import controls. Import opens a preview. Applying a profile uses AppModel.applySettingsProfile(_:).
Transfer tests and documentation Tests/DilatedUITests/SettingsProfileTests.swift, Tests/DilatedUITests/MountedSettingsTests.swift, docs/AUTOMATION.md	Tests cover profile validation, file operations, application, and preview actions. Documentation describes transferred and local settings and import limits.

DriveAlive test setup

Explicit mount-watch test configuration Tests/DilatedUITests/DriveAliveTests.swift	Five controller constructions now explicitly pass watchMounts: false.

Merge Risk: Minimal · up to 0be7a

Adds export and import of portable preferences with a preview step and explicit Apply. Safety policy, hotkeys, triggers, and local assets are left untouched. No actionable merge-blocking risk was found. The native file panels have not been exercised on a desktop, so a quick manual check is worthwhile.

@coderabbitai review

Threat model: a single-user local macOS app importing a user-selected JSON preferences file. Review bounded file handling, schema validation, preview/apply/cancel behavior, persistence failures, and preservation of safety policy, Stop state, active holds and local assets. Hostile local users racing their own filesystem are outside scope.

Reviewed current head 0be7a18. The transfer schema contains portable preferences, file reads are bounded and restricted to regular files, and apply persists before updating preferences. Safety policy, local assets, Stop state and active holds are preserved. Automated failure cases and mounted Apply/Cancel controls passed, along with 682 direct and 633 MAS Swift tests, release/bundle/web checks and local Qlty. Both current verify jobs and Codecov are green. Native file panels remain unverified. The first actual CodeRabbit review is still required before merge; this approval does not replace it.
