Crate layover_core 

Domain types for Layover.

This crate holds the parts of the design that can be reasoned about and tested without spawning anything. It reads configuration and prompt files from disk; it does not run processes, serve HTTP or call an LLM.

• agent — who an agent is: name, description, purpose, access
• route — edges in the route map
• pipeline — named entry points, their triggers and their flags
• prompt — composing an agent’s instructions from files, conditional on flags
• config — parsing a factory definition from layover.toml
• graph — the route map as a directed graph
• validate — load-time checks that fail before a human stops watching
• flight — the message envelope
• cost — the ledger, rate cards and the factory-wide Fuel Reserve
• itinerary — Hops, Fuel and the deterministic run cap
• barrier — rendezvous joins, including reset and reachability-based abandonment

See docs/architecture.md and docs/routing.md in the repository for the design these types implement.

Modules

agent

Agent identity and configuration.

autostart

Starting Layover when the computer starts.

barrier

Rendezvous joins.

brief

The block of text a run is given beyond its own instructions.

config

Parsing of the single layover.toml factory definition.

cost

What a run actually cost, and where that figure came from.

diagram

Drawing a factory.

flight

The Flight envelope, and the identifiers that track work through the Tower.

graph

The route map as a directed graph.

handover

Starting a run that carries what an earlier one knew.

help

Agents asking for help.

itinerary

Hops, Fuel and the deterministic run cap.

layover

A Layover: work set down now and picked up later.

learning

Agents proposing how to do better next time.

mcp

MCP servers an agent may reach.

payload

What a run is told, and in what order.

pipeline

Pipelines: named, triggerable entry points that carry flags.

prompt

Dynamic prompt composition.

queue

Work that has been asked for and not yet dispatched.

report

What an agent writes about its own run.

route

Edges in the route map.

run

What a run was, once it is over.

slots

Slots: how many runs may be in the air at once.

stall

A chain that stopped and will not start again on its own.

tools

The tools an agent may call, named once.

validate

Load-time validation of a factory definition.
