Design sensitivity
Where your reactor sits on its polarization curve, and which design knobs move the headline outcomes — using the mechanistic closure on the axes it was validated skillful on (power↔substrate/pH, current↔external resistance). Validated against the within-paper corpus trend; absolute values are model estimates.

Power (mW/m²) vs Substrate (mg/L)
Direction validated within-design (substrate→power, dirAcc ~63%).
Power (mW/m²) vs Anolyte pH
Direction validated within-design (pH→power, dirAcc ~62%).
Current (A/m²) vs External resistance (Ω)
Direction validated within-design (R_ext→current, dirAcc ~71-78%, load-line).
Not shown by design: power vs external resistance (the closure's matched-load peak is mislocated) and current vs substrate/pH (the closure predicts the wrong direction — current within a paper is load-dominated). Surfacing only validated axes keeps the tool honest. Seedocs/agent-team/sim-phase1a-loadline-results-2026-06-08.md.
