ChronoQuit

Intelligent auto-quit for macOS.

Encodes running apps across CDE dimensions (session timeline, app state, user environment, policy) to decide log, prompt, or exit — without simple timeouts.

Background

CDE Implementation

Dimensions

• Session timeline: timestamped events (launch, quit, focus change, prompts).
• App state: foreground/background, window metrics, and process state.
• User environment: OS version, device model, hardware flags.
• Policy: rules for when to prompt, log, or exit.

Query Workload

ChronoQuit is optimized for:

• "Given a sequence of session events, decide whether to log, prompt, or exit."
• "Aggregate sessions by user or device for analytics and tuning."
• "Detect patterns of problematic usage that should trigger intervention."

Minimal Sufficient Statistic

For a quit-helper utility, behavior and analytics are fully determined by:

• Session events,
• App state,
• Environment, and
• Policy.

Any other details are derived from those, so this CDE is an MSS for ChronoQuit's operational and analytic workloads.
