Rewrites the opening as state rather than a chronicle of the last few
commits, and gives the parked rule its own section: what the owner asked
for in her words, the half that is written and works with the code in
it, the four ways of asking that were measured and what each did, the
seed that shows it most clearly, and the design question underneath --
which is the same one holding OrthoSize. Also folds the declared-length
rule into the invariants, brings the vocabulary to leftover, says the
suite is eight seconds and must stay that way, and writes out the image
replay rather than pointing at a file in /tmp.
