The lower bound of every context. Structurally empty — the framework reserves
no keys; every property on ctx is a middleware contribution. (At runtime a
seeded context carries a symbol marker so the entry call can distinguish it
from a platform argument; the marker is invisible to Object.keys iteration
of string keys and to the type.)
