Enum MemOrigin 

pub enum MemOrigin {
    ExplicitToml,
    RuntimeCreated {
        at: SystemTime,
        by_tool: &'static str,
    },
}

Provenance record attached to every writable-mem registration.

MEM_NAME_COLLISION reads the colliding registration’s MemOrigin and renders it into details.source so agents can distinguish “collision with an explicit workspace mem” from “collision with a previously-runtime-created mem” without a follow-up round trip. The enum is kept internal to memstead-git-branch with a render_source rendering helper that produces the agent-facing string — no public serde derivation yet; the render path is the only supported serialization surface until a caller needs structured consumption.

Variants

ExplicitToml

Loaded from the workspace’s .memstead/workspace.toml mems = [...] entry.

RuntimeCreated

Registered after Engine::init via Engine::register_mem_runtime — the path lifecycle tools take. at captures when the runtime registration happened (rendered as an RFC-3339 timestamp on the error surface); by_tool names the MCP tool that produced the registration (today always "memstead_mem_create", but kept extensible).

Fields

at: SystemTime

by_tool: &'static str

Implementations

impl MemOrigin

pub fn render_source(&self) -> String

Agent-facing string rendering consumed by MEM_NAME_COLLISION.details.source. The string is short, declarative, and identifies the registration site so agents can correlate the collision with something they can observe (.memstead/workspace.toml entry, timestamp).

The workspace config file lives at .memstead/workspace.toml. The error message points at the current path so an agent following the hint finds it.

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

Short discriminator consumed by memstead_health { include_config: true } to tag each writable-mem entry with an agent-readable origin string. Variants map to stable kebab-case tokens so downstream filters key on them.
