Summary

PlugCore gains HostSettings / SavedSlot (Codable) and SettingsStore, which writes JSON to ~/Library/Application Support/Plug/settings.json. EffectID and InputSource become Codable.
AudioEngine.savedState(for:) / restoreState(_:for:) save and restore each Audio Unit's fullState, so effect parameters come back too.
The app restores input, output (matched by device UID) and effects on launch, but never starts playing by itself. It saves after each change and on quit, since parameter edits in plugin windows aren't observed. States for units still loading are kept and saved unchanged, so a quick quit can't lose them.

Tested

Mac mini M4, macOS 15: in the bundled app, input, output, effects and an effect's slider all came back after quitting and reopening, as reported by the owner.
Linux, Swift 6.0.3: 17 tests pass, including new settings round-trip, missing-file and corrupt-file tests.
Not yet confirmed on the Mac: swift test, including the new engine test that an AUDelay parameter survives save and restore.

## Summary - `PlugCore` gains `HostSettings` / `SavedSlot` (Codable) and `SettingsStore`, which writes JSON to `~/Library/Application Support/Plug/settings.json`. `EffectID` and `InputSource` become Codable. - `AudioEngine.savedState(for:)` / `restoreState(_:for:)` save and restore each Audio Unit's `fullState`, so effect parameters come back too. - The app restores input, output (matched by device UID) and effects on launch, but **never starts playing by itself**. It saves after each change and on quit, since parameter edits in plugin windows aren't observed. States for units still loading are kept and saved unchanged, so a quick quit can't lose them. ## Tested - Mac mini M4, macOS 15: in the bundled app, input, output, effects and an effect's slider all came back after quitting and reopening, as reported by the owner. - Linux, Swift 6.0.3: 17 tests pass, including new settings round-trip, missing-file and corrupt-file tests. - Not yet confirmed on the Mac: `swift test`, including the new engine test that an AUDelay parameter survives save and restore. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_011C96TJ2L7nzVMFTH7raNu5
