"""Solomon: a document plus structured questions in, one probability per decision out.

    from solomon import service, api
    layer = service.service(store, engine, selection='serving/selection.json')
    server = api.serve(layer)

Reading order. `service` is the serving contract and the layer that reads the model's own letter logits.
`binding` is the identity check that refuses to serve a stack that is not the one that was measured, and
`calibration` the one positive scalar per answer type it carries. `semantics` and `reliability` are what a
probability means here; `readout` turns letter logits into one. `engine` is the served engine, built on
`engine_numerics` over `engine_cuda`; `heads` are the trained answer heads it reads through.
`engine_contract` and `engine_reference` hold the prompt blocks every answer type is asked with. The
`service_*` modules are the pinned chain the layer wraps, innermost first: `service_states`,
`service_checked`, `service_answers`, `service_heads`, `service_evidence`, `service_packages`, `serving`.

Every answer type is answered. There is no abstention on this path; see `service.ORDERING_DISCLOSURE`.
