Do blockchains deform under agentic pressure?

Rheology studies how materials behave under sustained stress, creep, yield, structural shift. Invarians applies this framework to blockchain infrastructure. The working hypothesis: as autonomous agents accumulate on-chain load, execution regimes don't break, they migrate. Progressively. Structurally. Since March 17, Labs has been tracking regime baselines across 6 L1×L2 pairs, updated hourly. Early observation on ETH × Optimism: 23% of windows already register S1D2, elevated demand pressure against a stable structural state. Correlation noted. Causality withheld. The reference frame will expand to L1 × L2 × Bridge once bridge calibration is complete. Two primitives are currently exposed to autonomous agents: Proof of Execution Context (PoEC) and Pattern Reference. A third is in development ε(t), a continuous measure of structural deformation as a function of agentic load over time. If the hypothesis holds, ε(t) will be the first quantitative signal of how agents reshape the infrastruct
