# `Parlora.Backends.Legion`
[🔗](https://github.com/hfiguera/parlora/blob/v0.1.0/lib/parlora/backends/legion.ex#L1)

Optional Legion 0.6.0 execution in isolated Lua agents.

Supply `:execution`, a request factory returning `%{model: model_spec,
task: string, operations: %{name => zero_arity_function}, result: mapper}`.
Tools call only these operations; their native results, not model claims,
reach the mapper. All supplied operations must succeed before `Tool.complete()`.
The model spec supports ReqLLM's `{provider, model, options}` form, allowing
transport options and controlled model fixtures. The host configures ReqLLM's
provider credentials separately; api_key is not accepted in tuple defaults.

Persistence, recovery, delegation and conversation sharing are unsupported.
Cancellation stops local work and leaves external outcomes uncertain.
