Struct SrvSpawnResult 

pub struct SrvSpawnResult {
    pub pid: u32,
    pub ws_endpoint: String,
    pub web_endpoint: String,
    pub instance_id: String,
    pub auth_key: String,
    pub host_reg_secret: String,
    pub pending_migrations: usize,
    pub started_at: String,
}

What the launcher learns about srv after it signals ready. Held by the launcher and used to populate env vars the host reads.

Fields

pid: u32

ws_endpoint: String

web_endpoint: String

instance_id: String

auth_key: String

host_reg_secret: String

Shared secret proving to srv that a host_ipc.Register call really comes from the paired host, not an agent process (agents share auth_key too — see crates/srv/src/server/service/host_ipc.rs). Minted once per spawn_srv call (same lifetime as auth_key) and given to both host and srv’s spawn env — see host_spawn.rs’s AGENTMUX_HOST_REG_SECRET env line and this file’s own AGENTMUX_HOST_REG_SECRET env line below. Survives every host-only crash-restart automatically, exactly like auth_key does (this struct is held in the launcher’s own stack frame across restarts — see SrvSpawnResult’s own doc comment above).

pending_migrations: usize

Number of data migrations still pending after the in-process startup run. Counted by srv at ESTART time (count_pending_migrations). Since SPEC_MIGRATION_SYSTEM_HARDENING Phase 1 a migration failure never reaches ESTART at all (srv exits 1 with MigrationFailed), so a non-zero value here means the count and the run disagree — e.g. the fresh-install ordering case runner.rs documents — and the status-bar shows its retry message for that.

started_at: String

RFC3339 timestamp captured when ESTART arrived. Carried on the result for --diag / debug observability; not currently propagated into env. F.7 cleanup audit: keep with allow + this note rather than delete — a future --diag srv printer is the natural reader.
