Store versions, not view strings

A registry is a list of prompt records. Apple does not host this list for you. You can start with a JSON file in the app bundle. Each record needs an id, a human title, the instruction text, a status, and the id it replaces.

struct PromptRecord: Codable, Identifiable {
    var id: String
    var title: String
    var instructions: String
    var status: String // draft | live | retired
    var replaces: String?
}

struct PromptRegistry: Codable {
    var feature: String
    var records: [PromptRecord]

    var live: PromptRecord? {
        records.first(where: { $0.status == "live" })
    }
}

One live record per feature. Drafts can sit in the file. Retired records stay so you can roll back. Do not delete the last good version.

Put the live id in your logs and in eval samples. Test AI behavior before you ship needs that id. Stream tokens and measure speed needs it too, because a longer instruction can raise TTFT.

Next, feed the live text into a Dynamic Profile.
