The passage around this formula

Let developer capability evolve as ht+1=ht+ℓt−dth_{t+1}=h_t+\ell_t-d_t. where ℓt\ell_t is learning from agent-assisted work and dtd_t is depreciation of skills no longer exercised. Both depend on workflow. Requiring developers to predict behavior, inspect evidence, and explain accepted changes can raise ℓt\ell_t . Delegating opaque work and reviewing only summaries can raise dtd_t .
