"""Central configuration overlay: the hive's config on top of the local one.

The hive (``hive/app.py``) stores one versioned document. An instance asks
for the layers that target it, merges them in order, and applies the result
over its own config — only the fields the hive names, everything else from
the local files. No document, or a document with no matching layer, means the
local config stands unchanged.

Reading order in ``navi.config``::

    navi.config.settings = bootstrap_settings(Settings)

which captures the local base, fetches (with the last-good cache as a
fallback), validates, and returns the overlaid settings object. The other
sections are picked up where they are built: ``apply_profiles_list`` in the
profile registry, ``overlay_llm_raw`` in the LLM registry,
``overlay_mcp_configs`` in the container.

A live push (``POST /config/notify`` from the hive) calls ``refresh``: hot
settings are rewritten in the live singleton, profiles are swapped in the
registry, and anything that needs a restart is reported as such instead of
being pretended into effect.
