Enum StateEvent 

pub enum StateEvent {
    FileVerdict {
        path: String,
        state: FileState,
    },
    BecameGreen {
        identity: BuildIdentity,
    },
    BecameRed,
}

The event stream emitted by the daemon’s green/red model. Every other subsystem subscribes to this; nothing calls the model directly.

Two flavours, deliberately distinct:

• FileVerdict — level: “this file is now X”. Idempotent; fine to re-emit the same state.
• BecameGreen / BecameRed — edges: the tree just crossed the green⇄red boundary. These are the latency-to-signal events the product is built around (“tells you the moment it doesn’t”): BecameRed is the instant the server must freeze on last-green; BecameGreen is the only thing that may trigger a build.

Variants

FileVerdict

A single file’s verdict (re)settled. Level-triggered.

Fields

path: String

state: FileState

BecameGreen

The tree transitioned red → green. Carries the identity of the now-green input set so the build can be triggered without a second round-trip to the model. Edge-triggered: emitted once per crossing.

Fields

identity: BuildIdentity

BecameRed

The tree transitioned green → red. The dev server must immediately stop advancing and keep serving the last green artifact. Edge-triggered.
