Crate jacquard_host_support 

Reusable host-support primitives for Jacquard transport/profile implementers.

jacquard-host-support exists to hold generic ownership, mailbox, bookkeeping, and host-side observational helpers that concrete transports, profiles, and hosts can reuse without pushing runtime-support infrastructure into jacquard-core or jacquard-traits.

Host Support Surface

This crate owns transport-neutral host-side helpers such as bounded raw ingress mailboxes, unresolved/resolved peer bookkeeping, in-flight claim guards, transport-neutral endpoint conveniences, and host-side topology read-model projectors. These helpers are reusable support primitives and observational utilities, not shared world-model vocabulary and not behavioral trait boundaries.

Ownership

jacquard-host-support may own generic support primitives for host tasks and observational read models, but it must not:

• redefine shared world-model types that belong in jacquard-core
• publish capability or driver traits that belong in jacquard-traits
• encode transport-specific semantics that belong in concrete transport crates
• implement router logic, engine logic, or canonical route publication
• stamp Jacquard Tick or OrderStamp internally

Concrete host and transport integrations may depend on this crate for ownership scaffolding, but canonical route truth, router progression, and transport-specific protocol behavior all stay outside this crate.
