Decay

Automatic expiration of stale state

Definition

Mechanism

Gradual attenuation: without reinforcement, Value V decreases over time. `half_life` determines the rate. Reinforcement resets or boosts V. V descends to `floor_value` and stops there; reaching the floor triggers a State change, and removal only where the floor is zero.

Invariants

  1. Monotone absent reinforcement: V does not increase unless reinforced.
  2. V never descends below `floor_value`.

Risks

Failure modes

  1. Unreachable removal

    `floor_value` is above zero, so V never reaches zero and a removal trigger set at zero never fires.
