The Refine seam asks four things of a backend, and the ActivityPods README
answers two: how its providers are configured, and that a declared shape tree
gets its own Data Registration and container on the Pod. It is silent on the
record shape and on whether update replaces or patches — the two the seam
cannot default, and the two that fail silently when wrong.
So the declaration is written before adoption instead of after: the surface is
marked as declared rather than measured, the domain conditions are stated at
full strength, and the two unknowns sit in Needs as requests addressed to the
provider. Reading their source to settle them is the one thing this project
does not do.
This branch had no contract manifest at all, so it gets one. It carries no
consume entry, because neither targeted backend publishes an engagement to
pull; the declaration anchors on the README's commit identity, resolved with
ls-remote, which names a state without fetching any content.
