promote-feature

Guides the staged promotion of a gated FeatureFlag variant to Dogfood, Preview, or Stable, and schedules the follow-up cleanup.

Overview

Feature flags have two interacting layers:

• Runtime (warp_core/src/features.rs): DOGFOOD_FLAGS, PREVIEW_FLAGS, RELEASE_FLAGS — enabled per-channel at startup.
• Compile-time (app/Cargo.toml + app/src/lib.rs): Cargo features in [features]. The default = [...] array enables a feature for all builds. enabled_features() in app/src/lib.rs bridges each Cargo feature to its FeatureFlag variant via #[cfg(feature = "...")].

Do not remove the flag immediately after promoting to Stable. Keep it for at least 1–2 release cycles so a rollback is a one-line PR (remove the entry from default). Use the remove-feature-flag skill for the cleanup step later.

Promote to Dogfood

Add the flag to DOGFOOD_FLAGS in warp_core/src/features.rs:

pub const DOGFOOD_FLAGS: &[FeatureFlag] = &[
    // ...
