The Change policy asks for a tag carrying the package name, and one now
exists for this version, so the pin moves off the authoring branch onto
`polyfill/v1.0.0-dev.15`.
That version answers standing requests of its own: a read of a document
named in `graphs` now reaches it before the query opens, a shape query
hands back the shape's objects rather than property bags, and the leaf
gained an "Asked for, not decided" list where an application's request
leaves a trace instead of living in a message.
