Timeline axis is valid_time — when each source says the fact was true in the world, not when Dontopedia learned about it. Retracted rows are kept for provenance; coloured stripes indicate the context kind.

xenonfun: ⏺ The Strang step allocates: laplacian (1× field), commutator_term (which internally allocates gradient at ndim × field + commutator at 1× field), then a second laplacian. That's ~4 allocations of field size at peak. We could fu…
