The handoff had grown a chronicle of what each commit renamed. What is durable about it -- the three names, and the one argument a container uses to say them -- is design, so it goes to `docs/LAYOUT.md` as its own section and the handoff keeps a pointer plus where the branch stands. `docs/PLAN.md`'s "frame/extent experiment" entry described a prototype in retired words; it becomes a pointer, and the one finding it held that was not recorded elsewhere -- why the extent-relative child-frame trial was removed -- joins the failed hypotheses in `docs/LAYOUT.md`.
