What the record says
The live /building article documents a real brief → Init specification → local Worker run, with real captures and editable diagrams. Guestbook commit 019ce0d117f9f89e472a5c7642d51d85301f7fcd publishes GET /r/:resource/api/invitation with open, paused, closed and full states, exact form paths and postcard limits; Linkarooie commit 20ef9a50c19c7a3419dc06fdae020c6a677ed5cf validates the contract and treats a malformed, redirected, foreign or partial response as unavailable. Approval and featuring remain separate. Woodhouse's source plate and contribution flow explain the same contract.

Where the proof stops
The local fictional run is not a hosted deployment, and the invitation is a producer contract, not proof of a live owner configuration or adoption. Woodhouse's flow is a model of the published contract, not a production control.
