Enum Actor 

pub enum Actor {
    Agent,
    Cli,
    App,
    External,
    Unknown,
}

Caller categories for the Actor: trailer and for picking an author signature. Agent, Cli, and App get their author from the paired ClientId when one is present; External always uses the synthetic external <external@memstead.io> identity (no client is known); Unknown falls back to the committer identity.

Variants

Agent

Cli

App

A human-driven application embedding or fronting the engine — the macOS app, the node app’s HTTP surface, any future UI consumer. Distinct from Agent (an LLM speaking MCP) and Cli (the memstead binary): ambient provenance needs “a human did this through app software” as its own category, with the paired ClientId naming which software spoke.

External

Unknown

Implementations

impl Actor

pub fn as_trailer(&self) -> &'static str

String form used for the Actor: trailer. Stable; downstream LLMs grep on these values.

pub fn from_trailer(s: &str) -> Option<Actor>

Inverse of Self::as_trailer. Returns None for any string outside the four canonical wire forms — readers that may encounter older or malformed values choose how to handle the absence (default to Actor::Unknown, surface a warning, …).
