Agent's optimization in unique-contract principal-agent problem with adverse selection is recast as stochastic target problem, enabling principal's objective as stochastic optimal control with partial information and state constraints.

Proposes using timing synchronicity and statistical surprise to detect per-action price impact, assuming fast adverse events indicate causation.
Non-unique time arising from event-driven order flow points to a foundational market incompleteness beyond usual no-arbitrage assumptions.
Derives a generalized European option pricing PDE from an operational-time log-price lattice with state-dependent transitions that converges to the Black-Scholes-Merton PDE under risk-neutral drift and constant volatility.
A coupled reaction-diffusion model of order books yields the LMF trade-sign long memory and square-root meta-order impact, reinterpreted as event-time versus physical-time statements with subordination effects.

Non-unique time and market incompleteness
Non-unique time arising from event-driven order flow points to a foundational market incompleteness beyond usual no-arbitrage assumptions.
