Layer 1: Past (The Foundation & Baseline)

• Core Focus: Proven capabilities, completed milestones, and historical velocity.
• Primary Metric: Achieved Accomplishment
• Role in the Architecture:
  • Serves as the single source of truth for completed deliverables.
  • Provides baseline data (cycle time, past blocker resolution rates, velocity) required to calculate accurate future estimations.
  • Establishes reference points for quality, compliance, and auditing.

Layer 2: Present (The Execution Context)

• Core Focus: Active operational throughput, active state tracking, and resource allocation.
• Primary Metric: Work in Progress (WIP)
• Role in the Architecture:
  • Tracks tasks currently undergoing execution.
  • Measures operational capacity and constraints (limiting WIP to prevent bottlenecks).
  • Continuously logs live execution metrics against the Past baseline to detect potential deviations early.

Layer 3: Future (The Predictive Risk & Resolution Window)

• Core Focus: Risk modeling, predictive scheduling, and contingency response planning.
• Primary Metrics:
  • Estimated Time of Obstacle ARRIVAL (ETOA): The calculated point in time or milestone when a predictable risk, dependency failure, resource constraint, or technical debt will intersect and block active progress.
  • Estimated Time of Obstacle-Respond DEPARTURE (ETOD): The target time or duration required to execute a mitigation strategy, clear the blocker, and resume normal operational flow.
• Role in the Architecture:
  • Establishes a Risk Window (\text{ETOD} - \text{ETOA}) that quantifies expected downtime or overhead.
  • Triggers automated or preemptive mitigations before the obstacle impacts Layer 2 (Present WIP).
  • Uses feed-forward loops to adjust operational expectations based on historical resolution capability (Layer 1).
