Chrome Tamer: Equilibrium-Driven Resource Allocation [v2.2]

"Resource sparsity is corrected not by deletion, but by intelligent mechanism design."

Chrome Tamer is a high-performance system-wide browser optimizer. It treats browser tabs as autonomous players in a Non-Cooperative Resource Game, enforcing a Nash Equilibrium where tab residence is strictly gated by its marginal utility relative to system-wide opportunity cost.

The Equilibrium Engine (v2.4)

Chrome Tamer replaces crude LRU heuristics with a dynamic Pruning Engine that monitors system memory pressure in real-time.

1. Memory-Pressure Awareness: Integrates chrome.system.memory to gate all pruning actions.
2. Social Cost Pricing: As RAM usage increases, the "tax" (cost) of keeping a tab open escalates dynamically.
3. Redundancy Penalty: Domain-level externalities are penalized non-linearly to prevent "Tab Swarming".
4. Transparent Scoring: The Live Debugger exposes the internal utility calculations for every tab.

The Scoring Formula (Mechanism Design)

The system calculates a Utility Score (U) for each tab:

U(t) = B(t) - [C_base(P) + C_redundancy(D, P) + C_pressure(P)]

Where:

• B(t): Individual Benefit. Decays via BenefitDecay / (IdleTime + 1).
• C_base(P): Dynamic Base Cost. Scaled by system pressure P to simulate higher scarcity.
• C_redundancy(D, P): Redundancy Externality. Non-linear penalty for multiple tabs from the same domain D, sharpened when pressure P is high.
• C_pressure(P): System Pressure Gate. Direct quadratic penalty based on current RAM headroom.

If U(t) < 0, the tab is considered a Dominated Strategy and is deallocated via chrome.tabs.discard().
