Struct LayeredGraphProvider 

pub struct LayeredGraphProvider<P, F>
where
    P: GraphConfigSource,
    F: GraphConfigSource,
{ /* private fields */ }

Tries the primary GraphConfigSource, falling back to the secondary when the primary reports the graph missing or has an infrastructure failure. A Misconfigured error is propagated, never masked by the fallback — matching greentic_aw_runtime::LayeredConfigProvider’s semantics exactly.

Fallback triggers:

• ConfigError::AgentNotFound — graph absent from the primary (HTTP registry doesn’t know it yet; local pack may have it).
• ConfigError::Internal — transient infrastructure failure (network timeout, 5xx) — local pack can serve as a degraded fallback.

Non-fallback (surfaces immediately):

• ConfigError::Misconfigured — corrupt document or bad auth token; the operator must fix the document — silently serving stale local data would mask the problem.
