- The watchdog now works by allowing all your user installed apps automatically.
If you want it to affect system apps too, you’ll need to add those manually to the blacklist.

Startup gating
Waits until Android finishes booting and SystemUI is alive.
Starts only after the system is fully usable.
Whitelist handling
Uses a persistent whitelist file.
Whitelisted packages are never touched.
Whitelist is the only protection for system apps.
Continuous scan loop (every 30 seconds)
Enumerates all currently running processes.
Skips:
itself,
empty or malformed entries,
whitelisted packages,
packages killed recently (cooldown enforced).
Decision model
System apps (UID < 10000):
Standby bucket is ignored.
If running and not whitelisted, they are eligible for termination.
Third-party apps (UID ≥ 10000):
Queries numeric standby bucket.
Only killed if bucket > 20 (FREQUENT, RARE, RESTRICTED).
ACTIVE (10) and WORKING_SET (20) are never touched.
Action
Eligible packages are terminated via cmd activity kill.
Kill time is recorded per package.
Fixed-string state updates prevent regex errors and corruption.
Stability controls
Cooldown prevents rapid re-kills and restart storms.
No thread counting, no heuristics, no guessing.
Deterministic decisions based on app state and policy.
Net effect
Aggressively cleans unused background apps.
Enforces strict control over non-essential system services.
Preserves foreground apps, recently used apps, and protected components.
Maintains long-term system responsiveness and resource headroom.

Startup gating
Waits for full system boot completion.
Waits until SystemUI is running to avoid early-boot interference.
Displays a toast to confirm the service is active.
API-aware compaction strategy
On Android 14+ (API ≥ 34):
Uses cmd activity compact system to trigger framework-managed system-wide memory compaction.
On older Android versions:
Enumerates all installed packages with UIDs.
Applies both some and full compaction per app to maximize reclaim.
This ensures compatibility and correct behavior across Android releases.
Initial compaction
Runs a full compaction cycle once after startup.
Allows the system to stabilize before entering the monitoring loop.
Screen-state monitoring loop
Polls screen state periodically using cmd deviceidle get screen.
Maintains counters to detect consecutive screen-off or screen-on states, avoiding false triggers.
Idle enforcement logic
If the screen is detected off twice consecutively:
Forces device idle using cmd deviceidle force-idle.
Marks idle as forced to prevent repeated calls.
Immediately runs a compaction cycle.
Sleeps for a long interval to avoid unnecessary churn.
If the screen is detected on twice consecutively:
Releases forced idle using cmd deviceidle unforce.
Returns control to normal Android power management.
Periodic maintenance
While the screen remains off:
Performs scheduled compaction at long intervals to reclaim memory steadily.
While the screen is on:
Sleeps lightly and avoids compaction to prevent foreground performance impact.
Stability guarantees
Idle forcing is stateful and reversible.
No compaction is spammed.
No interaction with foreground apps.
No dependency on heuristics like memory pressure or thread count.
Net effect
Reduces memory fragmentation over time.
Improves idle-time memory reclaim efficiency.
Preserves foreground responsiveness.
Works silently in the background with predictable, bounded behavior.
CoreShift Compaction acts as a low-frequency, idle-aware memory maintenance daemon, complementing Android’s own memory management without fighting it.
