The revised .ankra/ankra.yaml is committed to the setup branch and the stored parameters are reprojected from it; nothing is deployed. The revision is all-or-nothing: any refused member leaves the proposal exactly as it was. Every answered request is a 200 whose outcome the client must switch on - a refusal carries its reasons in refusals rather than as an empty changes list. ## OpenAPI ````yaml https://platform.ankra.app/openapi.json patch /org/applications/{application_id}/setup-contract openapi: 3.1.0 info: title: FastAPI version: 0.1.0 servers: - url: https://platform.ankra.app security: [] paths: /org/applications/{application_id}/setup-contract: patch: tags: - Applications API summary: Revise an application's proposed setup contract description: >- Change named defaults on the application's deploy option contract.

Clients switch on this: reading the changes list alone would render a refusal exactly like a request that needed no change. "applied" - the contract was rewritten, committed to the setup branch and reprojected onto the stored parameters. "already_matching" - every named default already held the requested value, so nothing was committed. "refused" - the proposal was left exactly as it was and refusals says why. "applied_contract_not_stored" - the revised descriptor was committed but the stored contract could not be reprojected from it, so the repository and the deploy form now describe different options. enum: - applied - already_matching - refused - applied_contract_not_stored title: Application Setup Revision Outcome type: string ApplicationSetupChange: description: >- One deploy-option default that moved. from is null when the option declared no default at all, which is a different fact from an empty one. properties: option: title: Option type: string from: anyOf: - type: string - type: 'null' title: From to: title: To type: string required: - option - from - to title: Application Setup Change type: object ApplicationSetupRefusal: description: >- One requested change that was not applied, and why. option is omitted when the whole request was refused rather than one member of it. properties: option: title: Option type: string reason: title: Reason type: string required: - reason title: Application Setup Refusal type: object ValidationError: properties: loc: items: anyOf: - type: string - type: integer title: Location type: array msg: title: Message type: string type: title: Error Type type: string required: - loc - msg - type title: ValidationError type: object ````
