🚀 Enhancement: Adaptive Execution Modes for DynamicPool

[Synaptic724]

🧠 Summary

Refactor DynamicPool and SwitchLock to support adaptive execution behavior through configurable bias, backpressure, and priority-based modes. This will enable DynamicPool to operate not just as a standard thread pool but as a burst-oriented, agent-aware control unit.

---

❗ Problem

Current limitations in DynamicPool:

• Threads idle even as work queues up — dead task risk.
• No backpressure when saturation occurs.
• No priority override — all tasks treated equally.
• SwitchLock assumes static flow — no pressure awareness.

These weaknesses limit the system’s usability for high-throughput or agentic workloads.

---

🎯 Goals

• Add execution modes: standard, bias-controlled, and burst.
• Support backpressure behaviors:
  • wait
  • defer
  • reject
• Enable priority overrides that bypass normal scheduling.
• Introduce a new SwitchQueue object to internalize queue logic + control flow.

---

🛠️ Proposed Implementation

✅ Add Execution Modes

Example:

DynamicPool with configurable execution behavior:

• min_workers: 4
• max_workers: 12
• bias_enabled: True
• bias_pressure: 8
• backpressure_mode: wait (or reject, defer)
• allow_priority_override: True

---

✅ Core Additions

• SwitchQueue
  Combines:

  • Internal queue logic
  • SwitchLock integration
  • Pressure tracking
  • Override path

• Bias + Pressure Enforcement

  • Configurable pressure thresholds
  • Allows burst behavior with fallback to standard execution

• Thread-safe capacity awareness

  • Real-time tracking of idle threads
  • Dynamic wait/reject logic

• Graceful degradation + recovery

  • Pools adapt over time
  • Override/work re-queue path

---

🤖 Long-Term Vision

• DynamicPool becomes a burst-control node, not just executor.
• Threads become agentic, aware of pool pressure/state.
• Tasks negotiate for execution rights based on system conditions.
• Orchestrator can dynamically reconfigure pools at runtime.

---

🧪 Milestones

• Define SwitchQueue (queue + SwitchLock controller)
• Integrate SwitchQueue into DynamicPoolContainer
• Add config hooks for backpressure and priority
• Implement enforcement logic in SwitchQueue / DynamicPool
• Create edge-case test suite: idle drain, burst saturation, override behavior
• Document all execution modes

---

Let the pool evolve. Let threads choose. Let the system breathe.

⚠️ Extended Worker Starvation Scenario

Even when threads are present in the pool, we may experience worker starvation if:

Threads are blocked in long-running tasks.

Threads are waiting on SwitchLock bias to release.

Threads are not returning to the loop due to mismanaged lifecycle.

This creates the illusion of an idle system with tasks in queue but no progress, because all available workers are locked or waiting.
