hostbat

Generic deterministic module host for the BatPak family: mount content-identified modules over a syncbat Core and drive them with a deterministic startup/shutdown hook schedule.

hostbat adds what a raw syncbat::Core has no concept of — content identity (H_module per module + a HostFingerprint), modules that bundle operations + guard + hooks + jobs as one mountable unit, a generic Supervisor, and the host-control effect axis. It does not reimplement dispatch, receipts, or admission — those stay in syncbat; it lowers mounted modules into one syncbat::CoreBuilder and delegates invocation to the composed Core.

use hostbat::{HostBuilder, HostModule};

let module = HostModule::builder("my.module", 1)
    .operation(descriptor, handler)?
    .build()?;
let mut host = HostBuilder::new().mount(module)?.build()?;
let out = host.invoke("my.op", input)?;
