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
- Monotone absent reinforcement: V does not increase unless reinforced.
- V never descends below `floor_value`.
Risks
Failure modes
Unreachable removal
`floor_value` is above zero, so V never reaches zero and a removal trigger set at zero never fires.
